Złośliwy guz mózgu (rak mózgu)
Epidemiologia

Złośliwe guzy mózgu, stanowiące około 3% wszystkich nowotworów, charakteryzują się wysoką śmiertelnością i niską pięcioletnią przeżywalnością, która wynosi średnio 35,7%, a dla glejaka wielopostaciowego jedynie 6,9% z medianą przeżycia 8 miesięcy. Współczynnik zapadalności na złośliwe guzy mózgu i OUN wynosi około 6,89 na 100 000 osób rocznie, z wyższą częstością u mężczyzn (5,37/100 000) niż u kobiet (3,59/100 000), a szczyt zachorowań przypada na wiek 65-74 lata. Glejak wielopostaciowy stanowi około 47,7% wszystkich złośliwych guzów mózgu, a inne istotne typy to gwiaździaki, wyściółczaki, skąpodrzewiaki oraz pierwotne chłoniaki OUN. Epidemiologia wykazuje zróżnicowanie geograficzne i etniczne, z wyższą zapadalnością w krajach rozwiniętych i w populacji kaukaskiej. Nowotwory mózgu są drugą najczęstszą przyczyną zgonów nowotworowych u dzieci i młodzieży, a także znaczącym problemem zdrowotnym wśród osób starszych. Wskaźniki śmiertelności są podwyższone nie tylko z powodu samego nowotworu, ale także z powodu chorób serca (SMR=5,3), chorób naczyniowych mózgu (SMR=13,17) i innych przyczyn.

Epidemiologia złośliwego guza mózgu (raka mózgu)

Złośliwy guz mózgu (rak mózgu) stanowi istotny problem zdrowotny, mimo że należy do rzadziej występujących nowotworów. Nowotwory mózgu i ośrodkowego układu nerwowego (OUN) są ósmym najczęstszym nowotworem u dorosłych powyżej 40. roku życia i dziewiątym najczęstszym nowotworem ogółem, stanowiąc około 3% wszystkich nowo zdiagnozowanych przypadków nowotworów.12 Mimo postępów w leczeniu innych nowotworów, wskaźniki przeżywalności w przypadku złośliwych guzów mózgu pozostają na niezmienionym poziomie w ostatnich dziesięcioleciach.3

Częstotliwość występowania złośliwych guzów mózgu

Według danych z rejestrów nowotworowych, współczynnik zapadalności na złośliwe guzy mózgu i OUN wynosi około 6,89 na 100 000 osób rocznie, podczas gdy dla wszystkich guzów mózgu (złośliwych i niezłośliwych) wskaźnik ten wynosi 25,34 na 100 000 osób.4 W 2025 roku przewiduje się około 24 820 nowych przypadków nowotworów mózgu i układu nerwowego w Stanach Zjednoczonych, z czego około 18 330 osób umrze z powodu tej choroby.56 Złośliwe guzy mózgu stanowią około 30% wszystkich pierwotnych guzów mózgu i OUN.7

Częstość występowania złośliwych guzów mózgu różni się w zależności od regionu geograficznego. Zapadalność jest wyższa w krajach rozwiniętych, szczególnie w Stanach Zjednoczonych, Izraelu i krajach nordyckich, podczas gdy w Japonii i innych krajach azjatyckich wskaźniki są niższe.8 Światowy współczynnik zapadalności na pierwotne złośliwe guzy mózgu i OUN w 2022 roku, standaryzowany względem wieku według populacji światowej, wynosił 3,5 na 100 000 osób.9

Czynniki demograficzne

Złośliwe guzy mózgu występują częściej u mężczyzn niż u kobiet, z współczynnikiem zapadalności 5,37 na 100 000 dla mężczyzn i 3,59 na 100 000 dla kobiet.1011 Dysproporcja ta jest szczególnie widoczna w przypadku glejaka wielopostaciowego (glioblastoma), najczęstszego złośliwego guza mózgu, gdzie średni standaryzowany względem wieku współczynnik zachorowalności jest wyższy u mężczyzn (4,10) niż u kobiet (2,51).12

Wiek jest istotnym czynnikiem ryzyka. Wskaźniki zapadalności na złośliwe guzy mózgu rosną wraz z wiekiem, osiągając szczyt między 65 a 74 rokiem życia.13 Mediana wieku w momencie diagnozy dla glejaka wielopostaciowego wynosi 64 lata.14 Warto zauważyć, że nowotwory mózgu stanowią również znaczący problem zdrowotny wśród dzieci i młodzieży, będąc drugą najczęstszą przyczyną zgonów z powodu nowotworów w tej grupie wiekowej.15

Obserwuje się również różnice etniczne w zapadalności. Współczynniki zachorowalności na złośliwe guzy mózgu są wyższe wśród populacji kaukaskiej niż wśród Afroamerykanów (6,7 w porównaniu do 3,6 na 100 000).16 Jednakże wskaźniki śmiertelności są podobne wśród dzieci rasy białej i czarnej, co wskazuje na istotne dysproporcje w przeżywalności dzieci rasy czarnej.17

Wskaźniki przeżywalności

Pięcioletni względny wskaźnik przeżywalności po diagnozie pierwotnego złośliwego guza mózgu i OUN wynosi około 35,7%.1819 Wskaźnik ten znacząco różni się w zależności od typu histologicznego guza, jego lokalizacji, wieku pacjenta i czynników molekularnych. W przypadku glejaka wielopostaciowego, najczęstszego złośliwego guza mózgu u dorosłych, pięcioletni wskaźnik przeżywalności wynosi zaledwie 6,9%, a mediana przeżycia to tylko 8 miesięcy.2021

Istnieje wyraźna korelacja między wiekiem pacjenta a przeżywalnością. Pięcioletnie względne wskaźniki przeżywalności po diagnozie pierwotnego złośliwego guza mózgu i OUN według grup wiekowych wynoszą:22

  • 0-19 lat: 74,1%
  • 20-44 lat: 62,2%
  • 45-54 lat: 33,5%
  • 55-64 lat: 18,5%
  • 65-74 lat: 11,5%
  • 75 lat i więcej: 6,1%

22

Warto zauważyć, że nowotwory mózgu powodują najwyższą wśród wszystkich nowotworów utratę lat życia, zmniejszając średnią długość życia o około 27 lat.23

Trendy czasowe w epidemiologii złośliwych guzów mózgu

W ciągu ostatnich lat zaobserwowano zmiany w trendach zachorowalności na złośliwe guzy mózgu. Według niektórych badań, od 2004 do 2017 roku odnotowano istotny spadek w częstości występowania złośliwych guzów mózgu ogółem, przy jednoczesnym wzroście liczby diagnozowanych guzów niezłośliwych.24 Jednakże, w przypadku glejaka wielopostaciowego, najczęstszego i najbardziej agresywnego typu złośliwego guza mózgu, zaobserwowano wzrost współczynnika zapadalności o około 5,3% co trzy lata.25

Wzrost zachorowalności na glejaki wielopostaciowe może być częściowo związany z poprawą czułości i specyficzności metod diagnostycznych w ostatnich latach, co prowadzi do dokładniejszego rozpoznawania tego typu nowotworów.26 Ponadto, niektóre badania wskazują na wzrost zachorowalności na glejaki zlokalizowane w płatach czołowych i skroniowych mózgu, szczególnie wśród młodych dorosłych w wieku 20-29 lat.27

W Kanadzie odnotowano wzrost zarówno zapadalności, jak i chorobowości pierwotnych złośliwych guzów OUN o odpowiednio 37,5% i 40,5% w latach 1992-2017.28 Podobnie w Wielkiej Brytanii, standaryzowane względem wieku wskaźniki zachorowalności na guzy mózgu, OUN i guzy wewnątrzczaszkowe wzrosły o około 24% między latami 2000-2002 a 2017-2019.29

Czynniki ryzyka złośliwych guzów mózgu

Etiologia większości złośliwych guzów mózgu pozostaje nieznana. Jedynym dobrze udokumentowanym środowiskowym czynnikiem ryzyka jest ekspozycja na wysokie dawki promieniowania jonizującego, szczególnie w dzieciństwie.3031 Około 5-10% pacjentów ze złośliwymi guzami mózgu ma historię rodzinną nowotworów mózgu, co sugeruje potencjalny wpływ czynników genetycznych.32

Zwiększone ryzyko zachorowania na złośliwy guz mózgu zaobserwowano wśród osób z:

3334

Natomiast czynniki immunologiczne mogą zmniejszać ryzyko wystąpienia złośliwych guzów mózgu.35 Badania sugerują, że osoby z większą skłonnością do alergii mogą mieć mniejsze ryzyko zachorowania na glejaka wielopostaciowego.36

Najczęstsze typy histologiczne złośliwych guzów mózgu

Wśród złośliwych guzów mózgu, glejaki stanowią największą grupę, odpowiadając za około 78% wszystkich pierwotnych złośliwych guzów mózgu.37 Glejak wielopostaciowy (glioblastoma) jest najczęstszym i najbardziej agresywnym typem, stanowiącym około 47,7% wszystkich złośliwych guzów mózgu i OUN.38 Inne częste typy złośliwych guzów mózgu to:

  • Gwiaździaki (astrocytoma)
  • Wyściółczaki (ependymoma)
  • Skąpodrzewiaki (oligodendroglioma)
  • Pierwotne chłoniaki OUN
  • Rdzeniak (medulloblastoma) – najczęstszy złośliwy guz mózgu u dzieci

3940

Warto zauważyć, że rozkład typów histologicznych różni się znacząco między dziećmi a dorosłymi. U dzieci częściej występują guzy zarodkowe, rdzeniaki i gwiaździaki o niższym stopniu złośliwości, podczas gdy u dorosłych dominują glejaki wielopostaciowe i oponiaki.41

Nadzór i rejestr złośliwych guzów mózgu

Gromadzenie danych epidemiologicznych dotyczących złośliwych guzów mózgu ma kluczowe znaczenie dla zrozumienia tendencji zachorowalności, monitorowania skuteczności leczenia i identyfikacji potencjalnych czynników ryzyka.42

Systemy nadzoru i rejestry nowotworów

W Stanach Zjednoczonych głównym źródłem danych na temat epidemiologii guzów mózgu jest Centralny Rejestr Guzów Mózgu (Central Brain Tumor Registry of the United States, CBTRUS), który gromadzi informacje o pierwotnych złośliwych i niezłośliwych guzach mózgu, OUN oraz guzach przysadki i szyszynki.43 CBTRUS pobiera dane z dwóch głównych krajowych źródeł: Narodowego Programu Rejestrów Nowotworów Centrum Kontroli i Zapobiegania Chorobom (CDC’s National Program of Cancer Registries, NPCR) oraz Programu Nadzoru, Epidemiologii i Wyników Końcowych Narodowego Instytutu Raka (National Cancer Institute’s Surveillance, Epidemiology and End Results, SEER).44

W Europie i innych częściach świata istnieją podobne rejestry, choć ich zakres i kompletność mogą się różnić. Międzynarodowa Agencja Badań nad Rakiem (International Agency for Research on Cancer, IARC) gromadzi dane na temat złośliwych guzów mózgu na poziomie globalnym.45

Wyzwania w nadzorze epidemiologicznym

Nadzór nad złośliwymi guzami mózgu napotyka różne wyzwania, w tym:4647

  • Różnice w definicjach przypadków i klasyfikacji histologicznej guzów mózgu
  • Zmiany w metodach diagnostycznych i kryteriach klasyfikacji w czasie
  • Różnice w praktykach kodowania i raportowania między instytucjami
  • Niekompletne dane, szczególnie w krajach o ograniczonych zasobach
  • Trudności w identyfikacji i klasyfikacji guzów w specyficznych populacjach, np. u dzieci

Badanie przeprowadzone przez Armed Forces Health Surveillance Division (AFHSD) wykazało, że standardowa definicja przypadku stosowana do identyfikacji złośliwych guzów mózgu u personelu wojskowego miała niższą wartość predykcyjną przy zastosowaniu jej do populacji pediatrycznej. Wskazuje to na potrzebę opracowania specyficznych definicji przypadków dla różnych grup wiekowych.48

Znaczenie nadzoru epidemiologicznego

Dane z systemów nadzoru epidemiologicznego mają kluczowe znaczenie dla:

  • Identyfikacji trendów w zapadalności i śmiertelności z powodu złośliwych guzów mózgu
  • Określenia grup o podwyższonym ryzyku
  • Oceny skuteczności interwencji medycznych i zdrowia publicznego
  • Planowania zasobów opieki zdrowotnej
  • Wspierania badań nad etiologią i czynnikami ryzyka

49

Konsorcjum Epidemiologii Guzów Mózgu (Brain Tumor Epidemiology Consortium, BTEC) powstało w celu połączenia wysiłków badaczy w identyfikacji czynników ryzyka, wyników leczenia i profilaktyki guzów mózgu.50

Znaczenie zdrowotne i społeczne złośliwych guzów mózgu

Złośliwe guzy mózgu stanowią istotne wyzwanie dla zdrowia publicznego ze względu na ich wysoką śmiertelność i znaczący wpływ na jakość życia pacjentów.51

Obciążenie systemów opieki zdrowotnej

Mimo że złośliwe guzy mózgu stanowią relatywnie niewielki odsetek wszystkich nowotworów (około 2%), odpowiadają za nieproporcjonalnie duże obciążenie systemów opieki zdrowotnej.52 Związane jest to z:

  • Wysokimi kosztami diagnostyki i leczenia
  • Długotrwałą opieką rehabilitacyjną i paliatywną
  • Znacznym obciążeniem ekonomicznym pacjentów i ich rodzin
  • Utratą produktywności z powodu przedwczesnych zgonów i niepełnosprawności

53

Złośliwe guzy mózgu są dziesiątą wiodącą przyczyną zgonów z powodu nowotworów zarówno wśród mężczyzn, jak i kobiet we wszystkich grupach wiekowych w USA.54 Stanowią one również ósmą najczęstszą przyczynę zgonów z powodu nowotworów w Wielkiej Brytanii.55

Zwiększone ryzyko zgonów nienowotworowych

Pacjenci ze złośliwymi guzami mózgu mają zwiększone ryzyko zgonu nie tylko z powodu samego nowotworu, ale również z innych przyczyn. Badanie oparte na danych z programu SEER wykazało, że pacjenci ci mają statystycznie wyższe ryzyko zgonu z powodu chorób serca (SMR=5,3), chorób naczyniowych mózgu (SMR=13,17), wypadków (SMR=2,97) i posocznicy (SMR=13,39) w porównaniu do populacji ogólnej.56

Zgony nienowotworowe stanowią znaczącą część śmiertelności wśród pacjentów ze złośliwymi guzami mózgu (6,5% wszystkich zgonów), przy czym choroby serca są najczęstszą przyczyną zgonu nienowotworowego (1,57% wszystkich zgonów).57

Implikacje dla zdrowia publicznego

Biorąc pod uwagę znaczne obciążenie związane ze złośliwymi guzami mózgu, istnieje pilna potrzeba:

  • Zwiększenia świadomości na temat objawów i czynników ryzyka złośliwych guzów mózgu
  • Poprawy dostępu do wczesnej diagnostyki i specjalistycznego leczenia
  • Intensyfikacji badań nad nowymi metodami leczenia i identyfikacją modyfikowalnych czynników ryzyka
  • Rozwoju multidyscyplinarnego podejścia do opieki nad pacjentami
  • Wspierania pacjentów i ich rodzin w radzeniu sobie z fizycznymi, poznawczymi i psychologicznymi skutkami choroby

5859

Szczególnej uwagi wymagają grupy o podwyższonym ryzyku, takie jak osoby starsze, które nieproporcjonalnie często dotyka ta choroba, oraz pacjenci z grup etnicznych o gorszych wskaźnikach przeżywalności.60

Perspektywy na przyszłość

Analiza trendów epidemiologicznych złośliwych guzów mózgu pozwala przewidywać przyszłe wyzwania i kierunki badań w tej dziedzinie.61

Przewidywane trendy epidemiologiczne

Prognozy wskazują na:

  • Wzrost liczby przypadków złośliwych guzów mózgu w krajach o starzejącej się populacji
  • Przewidywany 1,5% wzrost częstości występowania złośliwych guzów mózgu do 2030 roku w USA, co oznacza wzrost liczby diagnozowanych przypadków do około 30 000 rocznie
  • Wzrost pięcioletnich przypadków chorobowych złośliwych guzów mózgu w ośmiu głównych rynkach (USA, Francja, Niemcy, Włochy, Hiszpania, Wielka Brytania, Japonia i miejska część Chin) z 243 850 w 2020 roku do 303 136 w 2030 roku, przy rocznym wskaźniku wzrostu 2,43%

6263

Zmiany demograficzne, w tym starzenie się populacji, będą prawdopodobnie miały istotny wpływ na epidemiologię złośliwych guzów mózgu, ponieważ wiek jest kluczowym czynnikiem ryzyka.64

Kierunki badań

Przyszłe badania nad epidemiologią złośliwych guzów mózgu powinny koncentrować się na:

  • Zastosowaniu wysokoprzepustowych technik omicznych do identyfikacji nowych czynników ryzyka
  • Poprawie metod wykrywania i pomiaru ekspozycji środowiskowych
  • Identyfikacji biomarkerów molekularnych związanych z rozwojem i progresją złośliwych guzów mózgu
  • Badaniu wzorców geograficznych i czasowych w celu wykrycia potencjalnych czynników etiologicznych
  • Analizie potencjalnego wpływu nowych technologii (np. telefonów komórkowych) na ryzyko rozwoju złośliwych guzów mózgu

6566

Szczególnie istotne jest prowadzenie badań dotyczących potencjalnego związku między zwiększoną ekspozycją na promieniowanie jonizujące a wzrostem częstości występowania glejaka wielopostaciowego.67

Wyzwania i potrzeby

Główne wyzwania i potrzeby w zakresie epidemiologii złośliwych guzów mózgu obejmują:

  • Ustandaryzowanie klasyfikacji i kodowania guzów mózgu między różnymi rejestrami i krajami
  • Poprawę kompletności danych, szczególnie w krajach o ograniczonych zasobach
  • Zwiększenie świadomości na temat objawów złośliwych guzów mózgu wśród lekarzy podstawowej opieki zdrowotnej
  • Rozwój bardziej efektywnych metod nadzoru epidemiologicznego, szczególnie dla specyficznych populacji, takich jak dzieci
  • Integrację danych epidemiologicznych z danymi klinicznymi i molekularnymi

6869

Lepsza współpraca międzynarodowa w zakresie gromadzenia i analizy danych epidemiologicznych jest niezbędna dla zrozumienia globalnych wzorców zachorowalności na złośliwe guzy mózgu i rozwoju skutecznych strategii interwencji.70

    A brain tumor is a growth of abnormal cells that have formed in the brain. Some brain tumors are malignant (cancerous), while others are not (non-malignant, non-cancerous or benign). A brain tumor can form in the brain or other parts of the central nervous system (CNS), such as the spine or cranial nerves. The brain plays a central role in the control of most bodily functions, including awareness, movements, sensations, thoughts, speech, and memory. A tumor can affect the brain’s ability to work properly and adequately perform such functions. […] Tumor grade has long been a way to define the aggressiveness of a tumor, particularly for malignant brain tumors such as glioma but also for non-malignant (benign) brain tumors including meningioma. […] Nearly one-third (27.9 percent) of brain and central nervous system (CNS) tumors are malignant.
  • #8 Brain tumor – Wikipedia
    https://en.wikipedia.org/wiki/Brain_tumor
    The incidence of brain tumors is higher in developed countries. […] The incidence of CNS tumors in the United States, Israel, and the Nordic countries is relatively high, while Japan and Asian countries have a lower incidence. […] In the United States in 2015, approximately 166,039 people were living with brain or other central nervous system tumors. Over 2018, it was projected that there would be 23,880 new cases of brain tumors and 16,830 deaths in 2018 as a result, accounting for 1.4 percent of all cancers and 2.8 percent of all cancer deaths. […] Brain, other CNS or intracranial tumors are the ninth most common cancer in the UK (around 10,600 people were diagnosed in 2013), and it is the eighth most common cause of cancer death (around 5,200 people died in 2012). […] In the United States more than 28,000 people under 20 are estimated to have a brain tumor. […] The average survival rate for all primary brain cancers in children is 74%. […] In children under 2, about 70% of brain tumors are medulloblastomas, ependymomas, and low-grade gliomas.

[…] In the period 1993-2017 examined here, GBs constituted 667/2102=31.7% of all malignant brain tumors in Genova (Tables 2 and 3), a fraction lower than the 48.6% reported in 2021 by Miller and colleagues in the US. […] The average AAR per 105 person-years for the GBs calculated over the eight three-year periods between 1993 and 2017 in both sexes was 3.22. […] The mean AAR for GB was higher in Genova males (4.10) than in females (2.51). […] GB AARs increased from 1993 to 2010 in Genova, both in males and females. […] The corresponding decrease recorded for NGB in 1993-2010 and NOS in 2004-2010 suggests that the increased temporal trend of GB AAR during 1993-2010 may have been at least partially linked to the significant advances in imaging and histopathology carried out in those years for the diagnosis of GB, to the detriment of diagnoses previously left unspecified (NOS) or incorrectly classified (NGB).

GBM accounts for 50.1 percent of all primary malignant brain tumors. It is estimated that more than 10,000 individuals in the United States will succumb to glioblastoma every year. The five-year survival rate for glioblastoma patients is only 6.9 percent, and the average length of survival for glioblastoma patients is estimated to be only 8 months. Survival rates and mortality statistics for GBM have been virtually unchanged for decades. Despite first being identified in the scientific literature in the 1920s, there have only been four drugs and one device ever approved by the FDA specifically for the treatment of glioblastoma. None of these treatments have succeeded in significantly extending patient lives beyond a few extra months. Glioblastoma is also one of the more expensive cancers to treat, often leaving patients and families with major financial hardship on top of the burdens of the disease.

But whether theyre cancerous or not, brain tumors can impact brain function and your health if they grow large enough to press on surrounding nerves, blood vessels and tissue. […] Approximately 78% of cancerous primary brain tumors are gliomas. […] Medulloblastoma is another type of cancerous brain tumor. These tumors are fast growing and form at the base of your skull. Theyre the most common cancerous brain tumor in children. […] The most serious type of brain tumor, glioblastoma, is becoming more common among people who are as the general population ages.

GBM accounts for 50.1 percent of all primary malignant brain tumors. It is estimated that more than 10,000 individuals in the United States will succumb to glioblastoma every year. The five-year survival rate for glioblastoma patients is only 6.9 percent, and the average length of survival for glioblastoma patients is estimated to be only 8 months. Survival rates and mortality statistics for GBM have been virtually unchanged for decades. Despite first being identified in the scientific literature in the 1920s, there have only been four drugs and one device ever approved by the FDA specifically for the treatment of glioblastoma. None of these treatments have succeeded in significantly extending patient lives beyond a few extra months. Glioblastoma is also one of the more expensive cancers to treat, often leaving patients and families with major financial hardship on top of the burdens of the disease.

    Research on mortality outcomes and non-cancer-related causes of death in patients with malignant brain tumors remains limited. This study aims to identify the prevalence of non-cancer-related causes of death after brain cancer (BC) diagnosis. […] Data of patients diagnosed with BC in the USA between 2000 and 2019 from the Surveillance, Epidemiology, and End Results (SEER) database were retrieved and analyzed. Standardized mortality ratios (SMRs) were calculated for all the reported causes of death. […] A total of 59,663 deaths were reported during the follow-up period.

[…] The average number of cases per year increased over time, from 1455 in 1992 to 2000 in 2017 (increase of 37.5%). […] The average disease duration during the study period was 19.7 months in children, 15.6 months in adults and 4.8 months in older adults. At 1 year after diagnosis, fewer males were alive than expected (observed: 765; expected: 819) (p = 0.048). Overall survival was shorter among males than among females. […] The incidence and prevalence of primary malignant CNS tumours increased steadily from 1992 to 2017. Males and older adults were disproportionately affected. Increased awareness and resources are needed to help address this disparity and provide support to these patient groups.

    Further research should be conducted, especially to assess risk factors such as radiation exposure and possible diagnosis of hereditary cancer syndromes. […] Clinicians in Lebanon should be highly suspicious in case of brain tumors due to the high malignancy rates. […] Our study revealed a very high percentage of malignant brain tumors; new policies should be implemented to improve research in this field and to ensure better screening and awareness. Further investigation is needed to evaluate the possible causes of the high incidence of pediatric glioblastomas and meningiomas in the Lebanese population.
