Zakażenie wirusem brodawczaka ludzkiego (hpv)
Epidemiologia

Wirus brodawczaka ludzkiego (HPV) jest najczęstszą infekcją przenoszoną drogą płciową, z około 80% aktywnych seksualnie osób zakażonych przynajmniej raz w życiu. Prewalencja HPV w populacji USA wynosi 40,0% (41,8% u mężczyzn, 38,4% u kobiet), a typy wysokiego ryzyka, takie jak HPV16 (3,2%) i HPV18 (1,4%), odpowiadają za większość nowotworów związanych z HPV, w tym 70% przypadków raka szyjki macicy. Zakażenia są szczególnie częste u kobiet poniżej 25 roku życia (24%) oraz w regionach takich jak Afryka Subsaharyjska (24%) i Ameryka Łacińska (16%). Czynniki ryzyka obejmują płeć, wiek, liczbę partnerów seksualnych oraz stan immunologiczny, z wyższą częstością zakażeń u osób z immunosupresją i HIV. U mężczyzn, zwłaszcza MSM, obserwuje się wyższą prewalencję zakażeń HPV, a obrzezanie wiąże się z mniejszym ryzykiem zakażenia. Przetrwałe zakażenie HPV wysokiego ryzyka jest głównym czynnikiem etiologicznym raka szyjki macicy oraz innych nowotworów anogenitalnych i gardła.

Epidemiologia i występowanie zakażenia HPV

Wirus brodawczaka ludzkiego (HPV) jest najczęstszą infekcją przenoszoną drogą płciową na świecie. 12 Szacuje się, że około 80% aktywnych seksualnie kobiet i mężczyzn zostanie zainfekowanych wirusem HPV przynajmniej raz w ciągu swojego życia. 34 Każdego roku diagnozuje się około 6,2 miliona nowych zakażeń HPV w Stanach Zjednoczonych, a obecnie zakażonych jest około 20 milionów osób. 5 Na całym świecie w 2019 roku HPV spowodował szacunkowo 620 000 przypadków nowotworów u kobiet i 70 000 przypadków nowotworów u mężczyzn. 67

Rozpowszechnienie infekcji HPV na świecie

Globalne dane pokazują, że 12% kobiet jest HPV DNA-pozytywnych, przy czym wskaźniki różnią się w zależności od wieku i kraju. 8 Najwyższe wskaźniki zakażeń HPV występują u młodszych kobiet, z odsetkiem 24% u kobiet poniżej 25 roku życia. 9 Najwyższa częstość występowania HPV u kobiet jest obserwowana w Afryce Subsaharyjskiej (24%), następnie w Ameryce Łacińskiej i na Karaibach (16%), wschodniej Europie (14%) i Azji Południowo-Wschodniej (14%). 10

W grupie wiekowej 15-59 lat w Stanach Zjednoczonych w latach 2013-2016 prewalencja jakiegokolwiek zakażenia HPV wynosiła 40,0% ogółem, 41,8% wśród mężczyzn i 38,4% wśród kobiet. 11 Prewalencja infekcji HPV związanej z chorobami wynosiła 22,0% ogółem, 24,2% u mężczyzn i 19,9% u kobiet. 12

Najczęstsze typy HPV na świecie to HPV16 (3,2%), HPV18 (1,4%), HPV52 (0,9%), HPV31 (0,8%) i HPV58 (0,7%). 13 Typy wysokiego ryzyka HPV są również nierównomiernie rozmieszczone, przy czym HPV16 ma wskaźnik około 13% w Afryce i 30% w Azji Zachodniej i Środkowej. 14

Czynniki ryzyka zakażenia HPV

Największe czynniki ryzyka zakażenia to płeć, wiek i aktywność seksualna, przy czym najwyższe wskaźniki są konsekwentnie obserwowane u aktywnych seksualnie kobiet poniżej 25 roku życia. 15 Ryzyko zakażenia HPV jest głównie związane z zachowaniami seksualnymi, w tym z większą liczbą partnerów seksualnych w ciągu życia i w ostatnim czasie. 1617

U mężczyzn, liczba partnerów seksualnych w ciągu życia była najważniejszym czynnikiem ryzyka nabycia zakażenia HPV, a obrzezanie zostało powiązane ze zmniejszonym wykrywaniem zakażenia HPV. 18 Zmiany w układzie odpornościowym również odgrywają rolę – osoby z immunosupresją oraz żyjące z HIV są szczególnie narażone na zakażenie HPV i choroby związane z HPV. 1920

Różnice epidemiologiczne między płciami

Epidemiologia HPV jest heterogenna między płciami, z wyższą częstością występowania zakażeń w okolicach analno-genitalnych wśród mężczyzn, co jest jeszcze wyższe w niektórych podgrupach. 2122 Badania wykazały, że zakażenia HPV mogą być mniej skłonne do utrzymywania się u mężczyzn niż u kobiet. U mężczyzn mediana czasu do eliminacji jakiegokolwiek zakażenia HPV wynosiła 5,9 miesiąca, przy czym 75% zakażeń ustępowało w ciągu 12 miesięcy. 23

Szczególnie wysokie wskaźniki zakażeń HPV obserwuje się wśród mężczyzn mających kontakty seksualne z mężczyznami (MSM). W jednym z badań przeprowadzonych w Portoryko, zarażenie jakimkolwiek typem HPV, HPV wysokiego ryzyka i wieloma typami HPV było znacznie wyższe u MSM (p-wartość≤0,05). 2425 Wielowariantowa analiza regresji logistycznej wykazała, że bycie MSM było związane z jakimkolwiek (OR=4,5; [95%CI: 1,9-10,7]), HPV wysokiego ryzyka (OR=3,4; [95%CI: 1,1-10,3) i wielokrotnym zakażeniem analnym HPV (OR=3,6; [95%CI: 1,5-9,1). 26

Zakażenie HPV a nowotwory

HPV jest odpowiedzialny za prawie wszystkie przypadki raka szyjki macicy, 90% raków odbytu, 60-73% raków gardła (ustno-gardłowych), 40-50% raków prącia oraz 40% raków pochwy i sromu. 27 Typy HPV 16 i 18 powodują około 70% przypadków raka szyjki macicy na całym świecie. 28 HPV-16 sam w sobie jest związany z ponad 50% wszystkich przypadków raka szyjki macicy. 29

Globalnie, 4,5% wszystkich nowotworów można przypisać infekcjom HPV, które są odpowiedzialne za 8,6% przypadków nowotworów u kobiet (trzecia najczęstsza przyczyna, o wysokiej śmiertelności) i 0,8% u mężczyzn. 30 Rak szyjki macicy był czwartą najczęstszą przyczyną nowotworów i zgonów z powodu nowotworów u kobiet w 2022 roku, z około 660 000 nowych przypadków i około 350 000 zgonów na całym świecie. 31

Różnice geograficzne w występowaniu nowotworu szyjki macicy

Najwyższe wskaźniki zachorowalności i umieralności na raka szyjki macicy występują w krajach o niskim i średnim dochodzie. 32 Odzwierciedla to poważne nierówności wynikające z braku dostępu do krajowych programów szczepień przeciwko HPV, badań przesiewowych w kierunku raka szyjki macicy i usług leczniczych, a także uwarunkowań społecznych i ekonomicznych. 33

Rak szyjki macicy stanowi jedynie 2% wszystkich nowotworów w krajach rozwiniętych, ale wynosi 7% w krajach rozwijających się. 34 W wielu krajach mniej rozwiniętych rak szyjki macicy jest najczęstszym nowotworem wśród kobiet z powodu braku skutecznych programów przesiewowych monitorujących cytologię szyjki macicy za pomocą badania Pap. 35

Zmiana trendów w nowotworach związanych z HPV

W ostatnich dziesięcioleciach nowotwory gardła spowodowane przez HPV wzrosły w Kanadzie i na całym świecie. Rak gardła (nowotwór ustno-gardłowy) jest obecnie najczęstszym typem nowotworu związanego z HPV w Kanadzie. 36 W Stanach Zjednoczonych odnotowano 28% wzrost wszystkich przypadków raka ustno-gardłowego (OPSCC), 225% wzrost HPV+ OPSCC i 50% spadek HPV- OPSSC. Obecnie jest to najczęstszy nowotwór związany z HPV w USA, przewyższający raka szyjki macicy. 37

W Stanach Zjednoczonych zwiększone wykorzystanie badań przesiewowych Pap i leczenia stanów przedrakowych przed ich progresją do raka w ciągu ostatnich dziesięcioleci zmniejszyło zachorowalność i śmiertelność z powodu raka szyjki macicy. 38 W latach 2012-2016 zachorowalność na inwazyjnego raka szyjki macicy w Stanach Zjednoczonych wynosiła 7,2 na 100 000 kobiet, przy ponad 12 000 nowych przypadków zgłaszanych rocznie. 39

Typy HPV i ich rozkład

Wirus brodawczaka ludzkiego (HPV) to nazwa grupy 200 znanych wirusów. 40 Obecnie zidentyfikowano około 218 typów HPV jako powodujących zakażenia u ludzi. 41 HPV jest grupą ponad 200 typów powiązanych wirusów, z których około 40 zakaża okolice narządów płciowych, jamy ustnej i gardła. 42

Klasyfikacja typów HPV

Typy HPV są klasyfikowane do dwóch głównych grup: wysokiego ryzyka i niskiego ryzyka. 43 Typy HPV wysokiego ryzyka mogą powodować raka szyjki macicy, pochwy, sromu, prącia, odbytu i gardła. Typy HPV niskiego ryzyka mogą powodować brodawki narządów płciowych i odbytu. 44

Około 40 typów HPV regularnie lub sporadycznie zakaża anogenitalny nabłonek płaski mężczyzn i kobiet. 45 Wirusy HPV wysokiego ryzyka narządów płciowych są prawdziwymi ludzkimi wirusami nowotworowymi lub onkogennymi i powodują raka szyjki macicy oraz część innych nowotworów anogenitalnych. 46

Około 15 typów onkogennych HPV jest związanych z rakiem szyjki macicy, przy czym HPV 16 i HPV 18 są najważniejsze. 47 Sekwencje DNA onkogennego HPV są wykrywane w około 50% raków prącia, sromu i pochwy. 48 Rak odbytu i zmiany prekursorowe, analna neoplazja śródnabłonkowa, w ponad 90% przypadków są związane z zakażeniem HPV. 49

Rozkład typów HPV w różnych regionach i populacjach

W Chinach całkowity skorygowany wskaźnik zakażeń HPV w populacji ogólnej waha się od około 13,1% do 18,8%, ze skorygowanym wskaźnikiem zakażeń 12,95-17,1% dla HPV wysokiego ryzyka i 3,28% dla HPV niskiego ryzyka. 50 Częstość występowania zakażeń HPV różni się w zależności od regionu i grupy populacyjnej, z zakresem około 14,9-16,0% na obszarach miejskich i około 13,7-16,3% na obszarach wiejskich. 51

W Ukrainie odsetek kobiet zakażonych HPV wynosił 34%, z czego większość (65%) była zakażona genotypami HPV wysokiego ryzyka, a w 90% przypadków było to zakażenie mieszane. 52 W strukturze wykrywania różnych genotypów HPV wysokiego ryzyka w Ukrainie: genotyp 16 – 23%, genotyp 53 – 16%, genotyp 31 – 14%, genotyp 33 – 11%, genotyp 66 – 11%, genotyp 68 – 11%. 53

Region Wskaźnik zakażenia HPV u kobiet (%) Najczęstsze typy HPV
Afryka Subsaharyjska 24% HPV16 (13%)
Ameryka Łacińska i Karaiby 16% HPV16, HPV18, HPV31
Europa Wschodnia 14% HPV16, HPV18, HPV31
Azja Południowo-Wschodnia 14% HPV16, HPV18, HPV58
Ameryka Północna 5% HPV16, HPV18, HPV31
Azja Zachodnia 2% HPV16 (30%)
Chiny 13.1-18.8% HPV52, HPV58, HPV16, HPV39, HPV51
Ukraina 34% HPV16 (23%), HPV53 (16%), HPV31 (14%)

Wpływ szczepień przeciwko HPV na epidemiologię

Od 2006 roku ponad 110 krajów wdrożyło kampanie szczepień przeciwko HPV, ale tylko około 40 krajów wprowadziło programy, które są neutralne pod względem płci. 54 Australia jako pierwszy kraj wdrożyła w pełni finansowany krajowy populacyjny program szczepień przeciwko wirusowi brodawczaka ludzkiego (HPV), którego celem jest zapobieganie zakażeniom HPV i chorobom związanym z HPV. 55

Programy szczepień i ich efektywność

Obecnie dostępne są trzy rodzaje szczepionek (dwuwalentna, czterowalentna i dziewięciowalentna), a wszystkie one są skierowane przeciwko dwóm najbardziej onkogennym genotypom wirusa (HPV 16 i 18). 56 Wszystkie licencjonowane szczepionki zawierają antygeny, które zapewniają ochronę przed stanami spowodowanymi przez typy HPV 16 i 18 i wykazano, że zapobiegają ponad 90% zmian przedrakowych związanych z tymi 2 typami wirusów. 57

W ostatnich latach omawiano potrzebę wdrożenia programów szczepień obejmujących wszystkie płcie w celu osiągnięcia odporności stadnej przeciwko HPV. 58 Pierwotna profilaktyka przeciwko HPV jest dostępna dzięki obecności szczepionek skierowanych przeciwko genotypom wysokiego ryzyka. 59

Dotychczas jedynym sposobem na przerwanie łańcucha transmisji są szczepienia, ale programy szczepień przeciwko HPV, szczególnie neutralne pod względem płci, są nadal w początkowej fazie w wielu krajach, zwłaszcza w krajach słabo rozwiniętych. 60 Osiągnięcie odporności stadnej jest niemożliwe, jeśli mężczyźni nie są włączeni do programów szczepień. 61

Szczepienia a przyszłe trendy epidemiologiczne

Coraz więcej dowodów wskazuje, że tylko neutralne płciowo szczepienia doprowadzą do znaczącej kontroli chorób związanych z HPV zarówno u kobiet, jak i mężczyzn oraz zmaksymalizują zapobieganie rakowi szyjki macicy, szczególnie jeśli zasięg szczepień dla dziewcząt w określonym regionie nie jest wysoki. 62

Profilaktyczne szczepionki przeciwko HPV, które zapewniają ochronę zarówno przed typami HPV wysokiego, jak i niskiego ryzyka, mają znacząco zmniejszyć obciążenie związane z chorobami związanymi z HPV. 63 Szczepienie jest jedną z najbardziej skutecznych strategii na całym świecie w celu zmniejszenia liczby nowotworów i zakażeń związanych z HPV. 64

Australia dostosowała swój cel eliminacji raka szyjki macicy jako problemu zdrowia publicznego do celów Światowej Organizacji Zdrowia (WHO) na rok 2030. 65 Do 2035 roku Australia zamierza osiągnąć cele wykraczające poza cele WHO: rozszerzenie 90% celu szczepienia przeciwko HPV, aby objąć zarówno mężczyzn, jak i kobiety. 66

Nadzór i monitorowanie zakażeń HPV

Zakażenia HPV i stany związane z HPV nie podlegają obowiązkowi zgłaszania w wielu krajach. 6768 Jednak inwazyjne nowotwory i nowotwory in situ (w tym nowotwory i stany przedrakowe spowodowane przez HPV) są zgłaszane do centralnych rejestrów nowotworowych. 69

Systemy nadzoru nad HPV

Dane dotyczące nadzoru nad nowotworami związanymi z HPV, w tym rakiem szyjki macicy, są zbierane w 2 populacyjnych centralnych rejestrach nowotworów NPCR i SEER, które razem zbierają dane o nowotworach zdiagnozowanych u 100% populacji USA. 70

Projekt monitorowania wpływu wirusa brodawczaka ludzkiego (HPV-IMPACT) to komponent Programów Pojawiających się Zakażeń (EIP) Centrów Kontroli i Zapobiegania Chorobom (CDC) w Stanach Zjednoczonych, będący współpracą między CDC, stanowymi departamentami zdrowia i uniwersytetami. 71 HPV-IMPACT to populacyjny system nadzoru, który ocenia wpływ i skuteczność programu szczepień przeciwko HPV, monitorując trendy w stanach przedrakowych szyjki macicy i rakach szyjki macicy. 72

W Norwegii od 2017 roku w ramach krajowego systemu nadzoru nad programem szczepień przeciwko HPV monitorowana jest częstość występowania genotypów HPV w raku szyjki macicy i prekursorach raka szyjki macicy. 73

Cele i metody nadzoru nad HPV

Główne cele systemów nadzoru nad HPV obejmują:

  • Monitorowanie trendów w ogólnej zapadalności na CIN2+ (w tym stany przedrakowe i inwazyjny rak) w czasie w określonych populacjach 74
  • Monitorowanie częstości występowania i rozkładu genotypów HPV w przypadkach przedraka CIN2+ u osób w wieku 18-39 lat i w przypadkach raka u osób w wieku powyżej 18 lat 75
  • Szacowanie i monitorowanie trendów w wykorzystaniu badań przesiewowych w kierunku raka szyjki macicy wśród mieszkańców obszarów objętych badaniem 76
  • Szacowanie odsetka pacjentów z CIN2+, którzy otrzymali szczepionkę przeciwko HPV i szacowanie skuteczności szczepionki 77

Specjalne badania mające na celu monitorowanie zakażeń HPV i chorób związanych z HPV mogą pomóc określić wpływ szczepionek przeciwko HPV. 78 Celem testów jest ocena skuteczności szczepionki przeciwko HPV w zakresie zachorowalności na HPV i dystrybucji genotypów HPV. 79

Rozwój i naturalna historia zakażenia HPV

HPV jest przenoszony przez bezpośredni kontakt skóra-skóra podczas aktywności seksualnej z osobą zakażoną, nawet gdy nie występują żadne objawy. 80 Infekcja HPV występuje, gdy wirus wnika do organizmu, zwykle przez nacięcie lub inne uszkodzenie skóry. 81 Zakażenia narządów płciowych HPV są nabywane poprzez stosunek płciowy, seks analny i inny kontakt skóra-skóra narządów płciowych. Niektóre zakażenia HPV rozprzestrzeniają się poprzez seks oralny. 82

Naturalna historia infekcji HPV

Większość zakażeń HPV jest przejściowych i bezobjawowych. Ponad 90% nowych zakażeń HPV, w tym tych spowodowanych przez typy HPV wysokiego ryzyka, ustępuje lub staje się niewykrywalna w ciągu 2 lat. 83 W 90% przypadków organizm kontroluje zakażenie samodzielnie. 84

Infekcja HPV, w przeciwieństwie do wielu zakażeń układu moczowo-płciowego, zwykle nie jest związana z natychmiastowymi objawami, takimi jak swędzenie, pieczenie i wydzielina z pochwy. Większość zakażonych HPV nie rozwinie choroby klinicznej ani objawów, ponieważ układ odpornościowy gospodarza eliminuje większość zakażeń. 85

Zakażenie HPV jest uważane za możliwe do przeniesienia zarówno podczas ostrych, jak i przetrwałych zakażeń. Można przypuszczać, że możliwość przenoszenia jest wysoka z powodu dużej liczby nowych zakażeń, które według szacunków występują każdego roku. 86

Zakażenie HPV a zmiany chorobowe

Przetrwałe zakażenie typami HPV wysokiego ryzyka jest powszechnie uznawane za główny czynnik przyczynowy rozwoju raka szyjki macicy. 87 Około 10% kobiet z zakażeniem HPV rozwija przetrwałe zakażenie, które może potencjalnie prowadzić do powstania zmian śródnabłonkowych niskiego stopnia (LSIL lub CIN 1, śródnabłonkowa neoplazja szyjki macicy stopnia 1) lub zmian śródnabłonkowych wysokiego stopnia (HSIL lub śródnabłonkowa neoplazja szyjki macicy stopnia 2 i 3). 88

Badania w Chinach wykazały również, że u pacjentów z różnymi stopniami zmian szyjki macicy i różnymi stopniami raka szyjki macicy, częstość występowania zakażenia HPV stopniowo wzrasta wraz z nasileniem stopnia zmiany. 89 Częstość występowania infekcji wynosiła 37,1% u kobiet z atypowymi zmianami komórek nabłonka płaskiego (ASCUS), 90,9% u kobiet ze zmianami płaskonabłonkowymi śródnabłonkowymi niskiego stopnia (LSIL) i 93,06% u kobiet ze zmianami płaskonabłonkowymi śródnabłonkowymi wysokiego stopnia (HSIL). 90

Badania przesiewowe i szczepienia przeciwko HPV

Obecnie rak szyjki macicy jest jedynym nowotworem spowodowanym przez HPV, dla którego dostępne są testy przesiewowe. 91 W Stanach Zjednoczonych zwiększone wykorzystanie badań przesiewowych Pap i leczenia stanów przedrakowych przed ich progresją do raka w ciągu ostatnich dziesięcioleci zmniejszyło zachorowalność i śmiertelność z powodu raka szyjki macicy. 92

Metody badań przesiewowych

Badanie komórek z szyjki macicy kobiety pod kątem HPV jest wykorzystywane do badań przesiewowych kobiet w kierunku raka szyjki macicy. Kobiety powinny być badane co 5-10 lat, rozpoczynając od 30. roku życia. Kobiety żyjące z HIV powinny być badane co 3 lata, począwszy od 25. roku życia. 93

Większość kobiet jest diagnozowana z HPV na podstawie nieprawidłowych wyników testu Pap. Test Pap jest podstawowym narzędziem przesiewowym w kierunku raka szyjki macicy lub zmian przedrakowych w szyjce macicy, z których wiele jest związanych z HPV. 94

Amerykańska Agencja ds. Żywności i Leków zatwierdziła jeden test DNA HPV do stosowania jako badanie kontrolne po nieprawidłowych wynikach badania Pap. 95 Silna korelacja między zakażeniem typami HPV wysokiego ryzyka a LSIL, HSIL i rakiem szyjki macicy sugeruje, że badanie DNA HPV byłoby użytecznym narzędziem do postępowania z kobietami z nieprawidłowymi wynikami testu Pap, zwłaszcza w przypadku tych z niejednoznacznymi wynikami badań. 96

Efektywność i znaczenie szczepień przeciwko HPV

Szczepionki przeciwko HPV oferują ochronę przed większością nowotworów związanych z HPV i brodawkami anogenitalnymi. Rutynowe szczepienia przeciwko HPV są zalecane dla wszystkich dzieci w wieku 11 lub 12 lat i mogą być rozpoczęte już w wieku 9 lat. 97

Szczepionki przeciwko HPV powinny być podawane wszystkim dziewczętom w wieku 9-14 lat, zanim staną się aktywne seksualnie. 98 Zdrowe Osoby 2020 określiły cel, jakim jest 80% objęcie szczepieniami 3 dawkami szczepionki przeciwko HPV dla kobiet w wieku od 13 do 15 lat po wprowadzeniu na rynek czterowalentnej szczepionki przeciwko HPV w 2006 roku. 99

Gardasil 9 to szczepionka przeciwko HPV zatwierdzona przez amerykańską FDA, która może być stosowana u mężczyzn i kobiet w celu ochrony przed rakiem szyjki macicy i brodawkami narządów płciowych. 100 Chociaż szczepionka czterowalentna przeciwko HPV wykazała skuteczność i bezpieczeństwo u mężczyzn, niska świadomość HPV u mężczyzn może być barierą dla jej stosowania w celu zapobiegania zakażeniom HPV. 101

Najskuteczniejszą strategią ograniczenia zachorowalności i rozwoju raka szyjki macicy jest wdrożenie kompleksowych programów badań przesiewowych. 102 Rozwój profilaktycznych szczepionek przeciwko powszechnym onkogennym i łagodnym typom HPV zrewolucjonizował nasze perspektywy zapobiegania nowotworom związanym z typami HPV 16 i 18, a także przeciwko typom niskiego stopnia 6 i 11. 103

  • #1 Human Papillomavirus Epidemiology and Prevention: Is There Still a Gender Gap?
    https://pmc.ncbi.nlm.nih.gov/articles/PMC10303003/
    Human papillomavirus (HPV) is sexually transmitted, one of the three most common sexually transmitted infections (STIs) in both males and females, and the most common viral STI. A crucial public health strategy to protect people against HPV is vaccination, which has shown its effectiveness in preventing HPV-related diseases. Presently, three types of vaccines are available (bivalent, quadrivalent, and nonvalent), and they all target the two most oncogenic virus genotypes (HPV 16 and 18). In recent years, the need to implement vaccination programmes that include all genders has been discussed in order to achieve herd immunity against HPV. To date, only a few countries have included young males in their vaccination programmes. Thus, our objective with this review is to provide an overview of the epidemiology of HPV and HPV prevention strategies and report the latest findings from the scientific literature.
  • #2 Chapter 11: Human Papillomavirus | Pink Book | CDC
    https://www.cdc.gov/pinkbook/hcp/table-of-contents/chapter-11-human-papillomavirus.html
    This chapter discusses pathogenesis, clinical features, epidemiology, vaccination, and surveillance of human papillomavirus, or HPV. […] Human papillomavirus (HPV) is the most common sexually transmitted infection in the United States. […] Epidemiologic studies demonstrating a consistent association between HPV and cervical cancer were published in the 1990s; more recently, HPV has been identified as a cause of certain other mucosal cancers. […] HPV infection is extremely common throughout the world. Most sexually active adults will have an HPV infection at some point during their lives, although they may be unaware of their infection. […] Humans are the only natural reservoir for HPV. […] HPV is transmitted through intimate, skin-to-skin contact with an infected person. […] HPV is presumed to be communicable during both acute and persistent infections. Communicability can be presumed high because of the large number of new infections estimated to occur each year.
  • #3 Human Papillomavirus Epidemiology and Prevention: Is There Still a Gender Gap?
    https://pmc.ncbi.nlm.nih.gov/articles/PMC10303003/
    HPV infections and related diseases affect both women and men. In fact, it is estimated that about 80% of sexually active women and men will be infected with HPV at least once during their lifetime. HPV infection is the second most common cause of cancer after gastric cancer, which is caused by Helicobacter pylori. However, the epidemiology of HPV differs between male and female populations. […] The epidemiology of HPV is heterogeneous between the sexes, with a higher prevalence of infection in ano-genital areas among males, which is even higher in some subgroups. To date, the only way to block the chain of transmission is vaccination, but HPV vaccination programs, especially gender-neutral ones, are still in their infancy in many countries, particularly in less-developed countries. This makes it difficult to achieve herd immunity, especially in males who were only invited to get vaccinated years after the first vaccine was introduced. There is growing evidence that only gender-neutral vaccination will lead to substantial control of HPV-related diseases in both women and men and maximize cervical cancer prevention, especially if the vaccination coverage for girls in a particular region is not high.
  • #4 Human Papillomavirus Epidemiology and Prevention: Is There Still a Gender Gap?
    https://www.mdpi.com/2076-393X/11/6/1060
    Human papillomavirus (HPV) infections are the most common sexually transmitted infections worldwide. They are prevalent in young women, but infections may also occur in sexually active adults. […] Globally, 4.5% of all cancers are attributable to HPVs, which are responsible for 8.6% of cancer cases in women (the third most prevalent cause, with a high mortality) and 0.8% in men. […] HPV infections and related diseases affect both women and men. In fact, it is estimated that about 80% of sexually active women and men will be infected with HPV at least once during their lifetime. HPV infection is the second most common cause of cancer after gastric cancer, which is caused by Helicobacter pylori. […] HPV-16 and 18 cause 90% of HPV-related cancers, although cases linked to HPV 45, 33, and 35 have been increasing.
  • #5 Epidemiology and Natural History of Human Papillomavirus Infections in the Female Genital Tract
    https://pmc.ncbi.nlm.nih.gov/articles/PMC1581465/
    Human papillomavirus (HPV) is the most common newly diagnosed sexually transmitted infection in the United States. Although the majority of sexually active adults will be infected with HPV at least once in their lives, it is sexually active women less than 25 years of age who consistently have the highest rates of infection. […] Approximately 6.2 million new HPV infections occur every year in the United States, and approximately 20 million individuals are currently infected. HPV is spread by skin-to-skin sexual contact and is prevalent in all sexually active populations. The Centers for Disease Control estimates that at least half of all sexually active individuals will acquire HPV at some point in their lives, whereas at least 80% of women will acquire an HPV infection by age 50. […] The greatest risk factors for infection are gender, youth, and sexual activity, with the highest rates being consistently found in sexually active women less than 25 years of age.

    Human papillomavirus (HPV) is the name of a group of 200 known viruses. They do not cause concerns in most people, but infection with some high-risk types is common and can cause genital warts or cancer. […] In 90% of people the body controls the infection by itself. Persistent HPV infection with high-risk HPV types is the cause of cervical cancer and is associated with cancers of the vulva, vagina, mouth/throat, penis and anus (1). […] In 2019, HPV caused an estimated 620 000 cancer cases in women and 70 000 cancer cases in men (1). […] Cervical cancer is the most common type of cancer caused by HPV, other less common cancers affecting men and women, including anal, vulvar, vaginal, mouth/throat and penile cancers. […] The highest prevalence of cervical HPV among women is in sub-Saharan Africa (24%), followed by Latin America and the Caribbean (16%), eastern Europe (14%), and South-East Asia (14%) (2).

    Globally, it is estimated that 620 000 new cancer cases in women and 70 000 new cancer cases in men were caused by HPV in 2019 (1). Cervical cancer was the fourth leading cause of cancer and cancer deaths in women in 2022, with some 660 000 new cases and around 350 000 deaths worldwide (3). Cervical cancers account for over 90% of HPV-related cancers in women (1). […] The highest rates of cervical cancer incidence and mortality are in low- and middle-income countries. This reflects major inequities driven by lack of access to national HPV vaccination, cervical screening and treatment services, and social and economic determinants. […] HPV vaccines should be given to all girls aged 9-14 years, before they become sexually active. […] Testing cells from a woman’s cervix for HPV is used to screen women for cervical cancer. Women should be screened every 5-10 years starting at age 30. Women living with HIV should be screened every 3 years starting at age 25.

Although the majority of sexually active adults will be infected with HPV at least once in their lives, it is sexually active women less than 25 years of age who consistently have the highest rates of infection. […] Approximately 6.2 million new HPV infections occur every year in the United States, and approximately 20 million individuals are currently infected. HPV is spread by skin-to-skin sexual contact and is prevalent in all sexually active populations. The Centers for Disease Control estimates that at least half of all sexually active individuals will acquire HPV at some point in their lives, whereas at least 80% of women will acquire an HPV infection by age 50.

The frequency of genital infections is associated with the number of sexual partners and the age of sexual debut. Patients receiving immunosuppressive drugs and those with defects in cell-mediated immunity, including those infected with HIV, are especially susceptible to developing HPV infections. […] The population-based incidence of genital warts was estimated at 106 cases per 100,000 population in Rochester, Minnesota (1975-1978) and at 160 cases per 100,000 population in Manitoba, Canada (1992), with the highest incidence rate among residents aged 20-24 years.

    It is currently recognized that besides the significant impact of human papillomavirus (HPV) infection in females, HPV causes substantial disease in men as well. Genital warts are a common manifestation of male infection with HPV. Genital warts are highly infectious and approximately 65% of people who have sex with an infected partner will develop warts themselves. More than 90% of genital warts are caused by non-oncogenic HPV types 6 and 11. […] Several cancers of the anogenital tract and upper aero-digestive tract, and their precursor lesions in men are now understood to be caused by infection with sexually transmitted HPV. For example, there is increasing incidence of anal cancer in western countries; however, there are limited data on its primary cause, anal canal HPV infection. Genital HPV infection is very common in men with an ongoing international study estimating a prevalence of 65.2% in asymptomatic males aged 18-70 years. Lifetime number of sexual partners was the most significant risk factor for the acquisition of HPV infection (P0.05), and circumcision has been associated with reduced detection of HPV infection in men. HPV infections may be less likely to persist in men than in women. In men, the median time to clearance of any HPV infection was 5.9 months, with 75% of infections clearing within 12 months. More data are needed to better understand the natural history of HPV infection. Although the quadrivalent HPV vaccine has been shown to be effective and safe in men, low awareness of HPV in males may be a barrier to its use for the prevention of HPV infection.

In fact, it is estimated that about 80% of sexually active women and men will be infected with HPV at least once during their lifetime. HPV infection is the second most common cause of cancer after gastric cancer, which is caused by Helicobacter pylori. However, the epidemiology of HPV differs between male and female populations. […] The epidemiology of HPV is heterogeneous between the sexes, with a higher prevalence of infection in ano-genital areas among males, which is even higher in some subgroups. To date, the only way to block the chain of transmission is vaccination, but HPV vaccination programs, especially gender-neutral ones, are still in their infancy in many countries, particularly in less-developed countries. This makes it difficult to achieve herd immunity, especially in males who were only invited to get vaccinated years after the first vaccine was introduced. There is growing evidence that only gender-neutral vaccination will lead to substantial control of HPV-related diseases in both women and men and maximize cervical cancer prevention, especially if the vaccination coverage for girls in a particular region is not high.

    Margaret Stanley describes what human papillomavirus is and how it causes disease. […] About 30-40 HPVs regularly or sporadically infect the anogenital squamous epithelium of men and women. […] The high-risk genital HPVs viruses are true human cancer or oncogenic viruses and cause cancer of the cervix and a proportion of other anogenital cancers. […] The majority of CIN1 infections will be cleared by immune responses. […] About 15 oncogenic HPV types are associated with cervical cancer, HPV 16 and HPV 18 being the most important. […] Oncogenic HPV DNA sequences are detected in about 50% of carcinomas of the penis, vulva and vagina. […] Carcinoma of the anus and the precursor lesion, anal intraepithelial neoplasia, is associated in more than 90% of cases with HPV infection. […] Cervical cancer contributes only 2% of all cancers in developed countries but to 7% in developing countries.

    The percentages of other cancers caused by oncogenic HPV are as follows: Anal cancer: 90%; Vulvar cancer: 40%; Vaginal cancer: 40%; Oropharyngeal cancer: 12%; Oral cancer: 3%. […] Globally, HPV infection is the most common STD. Genital warts have affected as many as 30 million individuals worldwide. […] In many less-developed countries, cervical cancer is the most common cancer among women due to the lack of effective screening programs that monitor cervical cytology by Pap smear. […] The prevalence of high-risk HPV in women with normal cervical cytology varies among different regions of the world. Although the global HPV prevalence is estimated to be approximately 12%, higher prevalences are noted in sub-Saharan Africa (24%), eastern Europe (21.4%), and Latin America (16.1%). […] In many developing nations, cervical cancer is the leading cause of cancer mortality among women. Worldwide, it is the second most common cause of cancer mortality among women. The World Health Organization (WHO) estimates that 570,000 new cases of cervical cancer occurred globally in 2018, and approximately 311,000 women died of cervical cancer during the same year.

    HPV is a group of over 200 types of related viruses. Around 40 of them infect the genital area, mouth and throat. […] HPV infections can cause: cancers and pre-cancerous lesions, anogenital warts (relating to the anus and genitals). […] The HPV types that are more likely to cause cancer are classified as high risk. […] HPV is responsible for nearly: 100% of cervical cancers, 90% of anal cancers, 60% to 73% of throat (oropharyngeal) cancers, 40% to 50% of penile cancers, 40% of vaginal and vulva cancers. […] Over the past few decades, cancers of the throat caused by HPV have been rising in Canada and worldwide. Throat (oropharyngeal) cancer is now the most common type of HPV-related cancer in Canada. […] For cervical cancer screening, your health care provider can give you a Pap test to detect abnormal cells in the cervix caused by HPV. […] There’s no routine screening available to detect precancerous cells for other HPV-related cancers. […] Most HPV infections go away without treatment within a couple of years. […] Treatments are available for anogenital warts or pre-cancerous and cancerous lesions.

    An important paper published in 2011 in the Journal of Clinical Oncology found there was a 28% increase in all OPSCC, a 225% increase in HPV+ OPSCC, and a 50% decrease in HPV- OPSSC. It is now the most common HPV-associated malignancy in the U.S., surpassing cervical cancer. […] Rates continue to increase and will likely increase by even more over the next 20 years until vaccination, Dr. Zevallos said. This is a clear and present problem that were facing on a daily basis in our clinics and across the country. […] OPSCC is primarily a problem in developed nations like the U.S. and Europe, though it is beginning in underdeveloped nations. Rural areas are just not as tested. […] About 85% of people will get an HPV infection in their lifetime. Vaccinating all 11-12 year-olds can protect them long before they are ever exposed. The CDC recommends two doses of HPV vaccine for all adolescents at age 11 or 12 years. […] HPV+ OPSCC has dramatically altered the epidemiology, demographics, and outcomes in HNC.

    HPV is the most common sexually transmitted infection (STI) in the United States. In 2018, there were about 43 million HPV infections in the US, many among people in their late teens and early 20s. HPV is transmitted through skin-to-skin contact, during vaginal, anal, or oral sex. Most people who become infected with HPV will not have any symptoms and will clear the infection on their own. Yet, when HPV infections persist, they might lead to abnormal Pap tests, genital warts, or cancer. […] There are many different strains of HPV, which are classified into two main groups: high risk and low risk. High-risk HPV can cause cancer of the cervix, vagina, vulva, penis, anus, and throat. Low-risk HPV can cause genital and anal warts. […] The HPV vaccine offers protection against most HPV related cancers and anogenital warts. Routine HPV vaccination is recommended for all children at age 11 or 12, and can begin as early as age 9. Catch up vaccination is available until age 26.

    The epidemiology of HPV infection in China has both similarities and differences compared to the global data. The total corrected HPV infection rate in the general population ranges from about 13.1-18.8%, with a corrected infection rate of 12.95-17.1% for high-risk HPV and 3.28% for low-risk HPV. The prevalence of HPV infection varies according to the region and the population group, with a range of about 14.9%-16.0% in urban areas and about 13.7%-16.3% in rural areas. The highest infection rates of total HPV, high-risk and low-risk types among women population were in East China, with 17.54%, 14.17% and 3.75%, respectively. The total HPV infection rate, high-risk and low-risk HPV type infection rates were higher in South China than in the North. HPV infection rates also vary by age groups. A multicenter cross-sectional survey study indicated that the rate of high-risk HPV infection in China showed a double-peak in puberty and perimenopause. Higher infection rates were observed in those younger than 25 and those between the ages of 41-45. The second peak of infection may be related to the increase in exposure to HPV, and the changes in the internal environment of the female organism and the immune system.

A crucial public health strategy to protect people against HPV is vaccination, which has shown its effectiveness in preventing HPV-related diseases. Presently, three types of vaccines are available (bivalent, quadrivalent, and nonvalent), and they all target the two most oncogenic virus genotypes (HPV 16 and 18). In recent years, the need to implement vaccination programmes that include all genders has been discussed in order to achieve herd immunity against HPV.

    Cervical cancer is the second most common cancer after breast cancer to affect women aged 1544 years in the European Union. The primary cause of cervical cancer is a persistent infection of the genital tract by some specific types of human papillomavirus (HPV). HPV is present in most cases of cervical lesions, which can further develop into cancer. At least 14 HPV types classified as high risk can cause cervical cancer in women, and are associated with other anogenital cancers and head and neck cancers in both men and women. HPV 16 and HPV 18 are the most common high-risk types, causing about 70 %of all cases of cervical cancer. […] All of the licensed vaccines contain antigens that provide protection against conditions caused by HPV types 16 and 18 and are shown to prevent more than 90% of precancerous lesions associated with these 2 types of viruses. […] The nine-valent vaccine additionally prevents more than 90% of precancerous lesions associated with HPV 31, 33, 45, 52 and 58 types. […] HPV vaccines are given in a two dose regimen over a six-month period for 9 to15 years old and in three doses to individuals aged 16 years or older.

    The purpose of this overview is to summarize recent studies in order to highlight how epidemiology and prevention strategies have developed in recent years. […] To date, vaccines provide the best and most cost-effective option for prevention. […] Primary prevention against HPV is available due to the presence of vaccines targeting high-risk genotypes; in fact, since 2006, more than 110 countries have implemented vaccination campaigns against HPV, but only about 40 countries have introduced programs that are gender-neutral. […] Herd immunity is impossible to achieve if males are not included in vaccination programs.

    HPV infections and related diseases affect both women and men. In fact, it is estimated that about 80% of sexually active women and men will be infected with HPV at least once during their lifetime. HPV infection is the second most common cause of cancer after gastric cancer, which is caused by Helicobacter pylori. However, the epidemiology of HPV differs between male and female populations. […] The epidemiology of HPV is heterogeneous between the sexes, with a higher prevalence of infection in ano-genital areas among males, which is even higher in some subgroups. To date, the only way to block the chain of transmission is vaccination, but HPV vaccination programs, especially gender-neutral ones, are still in their infancy in many countries, particularly in less-developed countries. This makes it difficult to achieve herd immunity, especially in males who were only invited to get vaccinated years after the first vaccine was introduced. There is growing evidence that only gender-neutral vaccination will lead to substantial control of HPV-related diseases in both women and men and maximize cervical cancer prevention, especially if the vaccination coverage for girls in a particular region is not high.

    A number of factors are associated with an increased risk of initial infection and/or clinical sequelae such as genital warts, CIN or invasive cancer. […] Immunosuppressed and HIV positive individuals are at a high risk of both HPV infection and HPV-associated disease. […] The strong correlation between infection with high-risk types of HPV and LSIL, HSIL, and cervical cancer suggests that HPV DNA testing would be a useful tool for the management of women with abnormal Pap test results, especially in the case of those with equivocal test results. […] HPV is one of the most common infections of the female genital tract, and it is also one of the most costly. HPV-associated health care costs include routine Pap tests, treatment of genital warts, follow-up of cytological abnormalities, and management of cervical malignancies. […] Prophylactic HPV vaccines that confer protection against both high- and low-risk HPV types are expected to substantially reduce the burden of HPV-associated disease.

    Vaccination is one of the most efficient strategies worldwide for reducing HPV-related cancers and infections. […] The implementation of vaccine campaigns has been an adequate strategy adopted by several countries attempting to reduce the incidence of HPV-related diseases. […] Cervarix®, Gardasil®, and Gardasil 9® are preventive vaccines directed to certain serotypes of HPV and they are designed as virus-like particles (VLP), meaning they resemble the external part of the HPV but do not have any infectious material in the inner side, making the vaccination safer. […] Even though the most popular types of vaccines are the prophylactic ones, used to prevent infection by HPVs, there are other kinds of vaccines called “therapeutic vaccines”, useful in treating patients who are already infected and present some symptoms caused by HPVs.

    HPV infection has been considered the most important worldwide, with about 570,000 new cases and over 300,000 attributable deaths in 2018. […] Persistent infection with high-risk HPV types is widely recognized as the primary causative factor for development of cervical cancer. […] Most HPV infections are transient and asymptomatic. More than 90% of new HPV infections, including those caused by high-risk HPV types, clear or become undetectable within 2 years. […] In the United States, increased use of Papanicolaou (Pap) screening and treatment of precancers before they progress to cancer during the past decades has reduced the incidence of and mortality from cervical cancers. […] In 2012-2016, invasive cervical cancer incidence in the United States was 7.2 per 100,000 women, with over 12,000 new cases reported annually.

    Globally, it is estimated that 620 000 new cancer cases in women and 70 000 new cancer cases in men were caused by HPV in 2019 (1). Cervical cancer was the fourth leading cause of cancer and cancer deaths in women in 2022, with some 660 000 new cases and around 350 000 deaths worldwide (3). Cervical cancers account for over 90% of HPV-related cancers in women (1). […] The highest rates of cervical cancer incidence and mortality are in low- and middle-income countries. This reflects major inequities driven by lack of access to national HPV vaccination, cervical screening and treatment services, and social and economic determinants. […] HPV vaccines should be given to all girls aged 9-14 years, before they become sexually active. […] Testing cells from a woman’s cervix for HPV is used to screen women for cervical cancer. Women should be screened every 5-10 years starting at age 30. Women living with HIV should be screened every 3 years starting at age 25.

    Most women are diagnosed with HPV on the basis of abnormal Pap tests. A Pap test is the primary cancer-screening tool for cervical cancer or pre-cancerous changes in the cervix, many of which are related to HPV. […] There is no cure for HPV infection, although in most women the infection goes away on its own. […] Cervical cancer is most treatable when it is diagnosed and treated early. […] The HPV vaccine is safe and effective in preventing the common infection and is recommended for teenagers and adults who were not vaccinated as children. […] Approximately 10 of the 30 identified genital HPV types can lead, in rare cases, to development of cervical cancer. […] Regular Pap testing and careful medical follow-up, with treatment if necessary, can help ensure that pre-cancerous changes in the cervix caused by HPV infection do not develop into life threatening cervical cancer.

    In the United States, Vietnamese women have the highest incidence of invasive cervical cancer (43 per 100,000); this probably reflects the lack of prior screening with a Pap smear, which can detect cervical cancer at an early treatable phase. […] There is no effective way to prevent HPV infection. […] According to Penny Hitchcock, chief of the Sexually Transmitted Diseases Branch of the U.S. governments National Division of Microbiology and Infectious Diseases, further research on topical microbicides and effective vaccines is critical. […] The U.S. Food and Drug Administration have approved one HPV DNA test for use as a follow-up to irregular Pap smears. […] A new vaccine against the most common strains of HPV may also be able to protect against 80 percent of cervical cancers.

    A number of factors are associated with an increased risk of initial infection and/or clinical sequelae such as genital warts, CIN or invasive cancer. […] Immunosuppressed and HIV positive individuals are at a high risk of both HPV infection and HPV-associated disease. […] The strong correlation between infection with high-risk types of HPV and LSIL, HSIL, and cervical cancer suggests that HPV DNA testing would be a useful tool for the management of women with abnormal Pap test results, especially in the case of those with equivocal test results. […] HPV is one of the most common infections of the female genital tract, and it is also one of the most costly. HPV-associated health care costs include routine Pap tests, treatment of genital warts, follow-up of cytological abnormalities, and management of cervical malignancies. […] Prophylactic HPV vaccines that confer protection against both high- and low-risk HPV types are expected to substantially reduce the burden of HPV-associated disease.

    HPV is the most common sexually transmitted infection (STI) in the United States. In 2018, there were about 43 million HPV infections in the US, many among people in their late teens and early 20s. HPV is transmitted through skin-to-skin contact, during vaginal, anal, or oral sex. Most people who become infected with HPV will not have any symptoms and will clear the infection on their own. Yet, when HPV infections persist, they might lead to abnormal Pap tests, genital warts, or cancer. […] There are many different strains of HPV, which are classified into two main groups: high risk and low risk. High-risk HPV can cause cancer of the cervix, vagina, vulva, penis, anus, and throat. Low-risk HPV can cause genital and anal warts. […] The HPV vaccine offers protection against most HPV related cancers and anogenital warts. Routine HPV vaccination is recommended for all children at age 11 or 12, and can begin as early as age 9. Catch up vaccination is available until age 26. Some adults ages 27-45 may decide to get the HPV vaccine based on discussion with their clinician, if they were not vaccinated when they were younger.

    HPV infection occurs when the virus enters the body, usually through a cut or other damage to skin. The virus spreads mainly by skin-to-skin contact. […] Genital HPV infections are contracted through having sex, anal sex and other skin-to-skin contact of the genitals. Some HPV infections spread through oral sex. […] HPV infections are common. Risk factors for HPV infection include: The more sex partners, the higher the risk of getting a genital HPV infection. Having sex with a partner who has had multiple sex partners also increases the risk. […] Certain strains of HPV can cause cervical cancer. These strains also might play a part in cancers of the genitals, anus, mouth and upper respiratory tract. […] Gardasil 9 is an HPV vaccine approved by the U.S. Food and Drug Administration and can be used for males and females to protect against cervical cancer and genital warts.

    It is currently recognized that besides the significant impact of human papillomavirus (HPV) infection in females, HPV causes substantial disease in men as well. Genital warts are a common manifestation of male infection with HPV. Genital warts are highly infectious and approximately 65% of people who have sex with an infected partner will develop warts themselves. More than 90% of genital warts are caused by non-oncogenic HPV types 6 and 11. […] Several cancers of the anogenital tract and upper aero-digestive tract, and their precursor lesions in men are now understood to be caused by infection with sexually transmitted HPV. For example, there is increasing incidence of anal cancer in western countries; however, there are limited data on its primary cause, anal canal HPV infection. Genital HPV infection is very common in men with an ongoing international study estimating a prevalence of 65.2% in asymptomatic males aged 18-70 years. Lifetime number of sexual partners was the most significant risk factor for the acquisition of HPV infection (P0.05), and circumcision has been associated with reduced detection of HPV infection in men. HPV infections may be less likely to persist in men than in women. In men, the median time to clearance of any HPV infection was 5.9 months, with 75% of infections clearing within 12 months. More data are needed to better understand the natural history of HPV infection. Although the quadrivalent HPV vaccine has been shown to be effective and safe in men, low awareness of HPV in males may be a barrier to its use for the prevention of HPV infection.

    Overall, HPV contributes to about 4% of all cancers, making HPV, and particularly HPV 16, a major global carcinogen. […] The acquisition of genital HPV occurs soon after the onset of sexual activity. […] Eight out of 10 of all sexually active women (and presumably men) will acquire a genital HPV infection at some point. […] The HPV type that is acquired is important. […] This data and the prevalence of the most common HPV types in CIN2/3 show that HPV 16 and HPV 18 are indeed the most pathogenic, the most dangerous of the high-risk HPV types. […] The development of prophylactic vaccines against the common oncogenic and benign HPV types has revolutionised our prospects for the prevention of the cancers associated with HPV types 16 and 18 and also against the low-grade types 6 and 11. […] These vaccines offer the opportunity, if delivered with high coverage and to the appropriate population, of significantly reducing the incidence of cervical cancer.
