Leukoplakia
Etiologia i przyczyny

Leukoplakia to potencjalnie złośliwe zaburzenie błony śluzowej jamy ustnej, manifestujące się białymi, nieusuwalnymi plamami lub płytkami, których etiologia jest wieloczynnikowa i często idiopatyczna. Kluczowymi czynnikami ryzyka są palenie tytoniu (obecne u ponad 80% pacjentów, zwiększające ryzyko 6-krotnie), nadużywanie alkoholu (ryzyko 8-krotnie wyższe) oraz używanie tytoniu bezdymnego i orzechów areki. Przewlekłe podrażnienia mechaniczne, infekcje (Candida albicans, HPV, EBV) oraz stany związane z zanikiem nabłonka (niedobory żelaza, witamin A i B, kiła) również przyczyniają się do rozwoju leukoplakii. Patogeneza obejmuje liczne mutacje genetyczne (m.in. TP53, CDKN2A, NOTCH1) i zmiany histopatologiczne (hiperkeratoza, dysplazja), które mogą prowadzić do transformacji nowotworowej. Ryzyko złośliwienia jest zmienne, od 0,1% do 17,5%, z wyższym ryzykiem w przypadku leukoplakii niejednorodnej i proliferative verrucous leukoplakia (PVL), gdzie ponad 60% może przekształcić się w raka jamy ustnej.

Etiologia i przyczyny leukoplakii

Leukoplakia jest potencjalnie złośliwym zaburzeniem błony śluzowej jamy ustnej, charakteryzującym się występowaniem białych plam lub płytek, których nie można scharakteryzować klinicznie ani histologicznie jako żadną inną określoną chorobę12. Etiologia leukoplakii jest wieloczynnikowa, a wiele przypadków ma charakter idiopatyczny (przyczyna nie jest znana)34. Występowanie leukoplakii jest związane z mutacjami genetycznymi, które powodują szybsze namnażanie się komórek tkanek jamy ustnej, prowadząc do tworzenia charakterystycznych płytek5.

Czynniki związane z tytoniem

Palenie tytoniu jest najczęściej wymienianym czynnikiem ryzyka rozwoju leukoplakii67. Ponad 80% osób z leukoplakią ma dodatni wywiad palenia tytoniu8. Osoby palące są sześć razy bardziej narażone na rozwój leukoplakii niż osoby niepalące910. Również używanie tytoniu bezdymnego, takiego jak tytoń do żucia lub tabaka, znacznie zwiększa ryzyko rozwoju leukoplakii1112.

W niektórych kulturach praktykuje się tzw. „odwrotne palenie”, gdzie dym z płonącego końca papierosa lub podobnego urządzenia jest zatrzymywany w jamie ustnej, co może powodować szereg zmian błony śluzowej jamy ustnej, w tym leukoplakię. W tych populacjach takie zmiany mają 19-krotnie zwiększone ryzyko transformacji złośliwej w porównaniu z kulturami, gdzie tytoń jest używany w inny sposób13.

Alkohol i używki

Nadmierne spożycie alkoholu jest drugim najczęstszym czynnikiem ryzyka związanym z leukoplakią14. Osoby nadużywające alkoholu są osiem razy bardziej narażone na rozwój tego schorzenia w porównaniu z osobami niepijącymi15. Alkohol może działać jako czynnik drażniący błonę śluzową i potęgować rakotwórcze działanie tytoniu16. Szczególnie wysokie ryzyko występuje u osób jednocześnie palących tytoń i spożywających alkohol17.

Używanie orzechów areki (betel) w wielu częściach świata, szczególnie w południowej i południowo-wschodniej Azji, stanowi również istotne ryzyko rozwoju leukoplakii1819.

Czynniki mechaniczne i przewlekłe podrażnienia

Przewlekłe podrażnienie błony śluzowej jamy ustnej może przyczyniać się do rozwoju leukoplakii20. Do czynników mechanicznych zalicza się:

  • Nieprawidłowo dopasowane protezy, aparaty ortodontyczne, płytki zgryzowe lub uzupełnienia protetyczne2122
  • Uszkodzone, nierówne lub ostre zęby trące o język2324
  • Nawykowe przygryzanie policzka lub wargi2526
  • Używanie bardzo twardych szczoteczek do zębów27
  • Galwanizm jamy ustnej (prądy galwaniczne indukowane przez protezy zębowe wykonane z różnych metali)28

Czynniki infekcyjne

Różne czynniki infekcyjne mogą odgrywać rolę w rozwoju leukoplakii:

Czynniki niedoborowe

Leukoplakia jest bardziej prawdopodobna w obszarach zaniku nabłonka. Stany związane z zanikiem błony śluzowej obejmują35:

Czynniki genetyczne i molekularne

Patogeneza leukoplakii jest w dużej mierze nieznana, ale uważa się ją za pośredni etap w karcinogenezie jamy ustnej, napędzany przez liczne somatyczne mutacje genetyczne wpływające na wzrost keratynocytów, przeżycie i kontrolę cyklu komórkowego42. Zmiany te prowadzą do modyfikacji histopatologicznych (hiperkeratoza, hiperplazja, dysplazja) i klinicznych (zmiana koloru, grubości i tekstury)43.

Wśród zmian genetycznych obserwowanych w leukoplakii wymienia się:

  • Zmiany liczby kopii DNA (amplifikacje, delecje, insercje) dotyczące znanych onkogenów (np. CDKN2A, CCND1, EGFR i MYC)44
  • Nieprawidłowości ploidii DNA45
  • Dodatnią aktywność telomerazy46
  • Utratę heterozygotyczności (szczególnie na 3p, 4q, 9p i 17p)47
  • Mutacje genów, najczęściej dotyczące TP53, a następnie NOTCH1, FAT1, CDKN2A, KMT2C i PIK3CA48

Inne czynniki ryzyka

Inne czynniki związane z rozwojem leukoplakii obejmują:

Znaczenie kliniczne etiologii w kontekście potencjału złośliwego

Zrozumienie etiologii leukoplakii ma kluczowe znaczenie ze względu na jej potencjał złośliwy. Choć sama leukoplakia nie jest nowotworem złośliwym, jest uważana za potencjalnie złośliwe zaburzenie jamy ustnej53.

Ryzyko transformacji nowotworowej

Ryzyko transformacji nowotworowej różni się w zależności od typu leukoplakii i obecności czynników ryzyka:

  • Badania pokazują, że mniej niż 15% osób z leukoplakią rozwija raka jamy ustnej54
  • Leukoplakia niejednorodna (non-homogenous) ma siedem razy większe prawdopodobieństwo złośliwienia niż typ jednorodny (homogenous)5556
  • Leukoplakia brodawkowata rozrostowa (proliferative verrucous leukoplakia, PVL) jest szczególnie niebezpieczna – niektóre badania sugerują, że ponad 60% osób z PVL rozwija raka jamy ustnej57
  • Ogólna częstość transformacji złośliwej w różnych badaniach waha się od 0,1% do 17,5%5859
  • W 5-letnim badaniu kohortowym bezwzględne ryzyko transformacji w nowotwór złośliwy wynosiło 3,3%60

Czynniki zwiększające ryzyko transformacji złośliwej obejmują61:

Szczególny przypadek – leukoplakia włochata

Leukoplakia włochata (hairy leukoplakia) jest odmienną jednostką chorobową spowodowaną przez wirusa Epsteina-Barr66. W przeciwieństwie do klasycznej leukoplakii, leukoplakia włochata nie jest zmianą przednowotworową i nie ma potencjału złośliwego6768. Jest ona jednak ważnym wskaźnikiem osłabienia układu odpornościowego, szczególnie u osób z HIV/AIDS i może być jednym z pierwszych objawów zakażenia HIV6970.

Implikacje kliniczne znajomości etiologii

Zrozumienie przyczyn leukoplakii ma kluczowe znaczenie dla skutecznej profilaktyki, diagnostyki i leczenia71.

Profilaktyka oparta na etiologii

Znajomość czynników etiologicznych pozwala na podjęcie działań profilaktycznych72:

  • Zaprzestanie używania tytoniu w każdej postaci (palenie, żucie)73
  • Ograniczenie spożycia alkoholu, szczególnie w połączeniu z tytoniem74
  • Zapewnienie prawidłowego dopasowania protez i innych uzupełnień protetycznych75
  • Regularne wizyty u stomatologa w celu korygowania ostrych krawędzi zębów lub wypełnień76
  • Utrzymywanie odpowiedniej higieny jamy ustnej77
  • Zbilansowana dieta bogata w witaminy A i B78

Podejście do leczenia w oparciu o etiologię

Leczenie leukoplakii często rozpoczyna się od identyfikacji i eliminacji czynnika wywołującego7980:

  • Jeśli przyczyną jest uszkodzony lub ostry ząb, przeprowadza się jego wygładzenie81
  • W przypadku źle dopasowanych uzupełnień protetycznych, dokonuje się ich korekty lub wymiany82
  • Jeśli stan jest spowodowany paleniem tytoniu, zaleca się zaprzestanie palenia8384
  • W przypadku podejrzenia refluksu krtaniowo-gardłowego jako czynnika przyczyniającego się do leukoplakii głośni, często stosuje się modyfikacje diety i stylu życia oraz/lub leki na receptę85
  • W przypadku leukoplakii włochatej związanej z EBV, leczenie może być skierowane na podstawową przyczynę osłabienia układu odpornościowego86

W przypadkach leukoplakii z dysplazją lub wysokim ryzykiem transformacji złośliwej, podejście diagnostyczne i terapeutyczne jest bardziej agresywne i może obejmować8788:

  • Biopsję w celu wykluczenia lub potwierdzenia obecności komórek nowotworowych89
  • Chirurgiczne usunięcie zmiany (klasyczne wycięcie skalpelem, krioterapię lub terapię laserem CO₂)90
  • Regularne monitorowanie w celu wczesnego wykrycia ewentualnych zmian nowotworowych, nawet po usunięciu zmian leukoplakii9192

Znaczenie etiologii w kontekście zdrowia publicznego

Znajomość czynników etiologicznych leukoplakii ma istotne znaczenie dla zdrowia publicznego i edukacji pacjentów93.

Leukoplakia jako schorzenie potencjalnie złośliwe wymaga świadomości zarówno wśród lekarzy, jak i pacjentów. Ogólnoświatowa częstość występowania leukoplakii wynosi około 2% i zwiększa się z wiekiem94. Większość przypadków leukoplakii występuje u mężczyzn między 50. a 70. rokiem życia, a mniej niż 1% przypadków dotyczy osób poniżej 30. roku życia9596.

Działania w zakresie zdrowia publicznego powinny koncentrować się na:

  • Edukacji na temat szkodliwości używania tytoniu i nadmiernego spożycia alkoholu97
  • Promowaniu regularnych kontroli stomatologicznych, szczególnie u osób z czynnikami ryzyka98
  • Zwiększaniu świadomości na temat wczesnych objawów leukoplakii i znaczenia szybkiej konsultacji medycznej99
  • Badaniach przesiewowych w grupach wysokiego ryzyka100

Szczególną uwagę należy zwrócić na leukoplakię włochatą jako potencjalny wskaźnik zakażenia HIV lub innego stanu osłabienia układu odpornościowego, co ma istotne znaczenie dla wczesnej diagnostyki i leczenia tych schorzeń101102.

    Oral leukoplakia is a white patch or plaque that develops in the oral cavity. The condition is potentially malignant and is strongly associated with tobacco use. […] The etiology of oral leukoplakia is multifactorial, and many causes are idiopathic. The most commonly associated risk factor is the use of tobacco in either smoked or smokeless form. Additionally, the use of areca (betel) nut preparations in many parts of the world (south and southeast Asia) poses a significant risk, as does the use of snuff and other forms of smokeless tobacco. […] The role of chronic candidiasis has been linked to the development of leukoplakia, in particular, nonhomogeneous leukoplakia.

    https://emedicine.medscape.com/article/853864-overview
    Oral leukoplakia (OL) is a white patch or plaque that cannot be rubbed off, cannot be characterized clinically or histologically as any other condition, and is not associated with any physical or chemical causative agent except tobacco or areca nut. Therefore, a process of exclusion establishes the diagnosis of the disease. […] The etiology of most cases of OL is unknown (idiopathic). In other cases, the initiation of the condition may depend on extrinsic local factors and/or intrinsic predisposing factors. Factors most frequently blamed for the development of idiopathic leukoplakia include tobacco use, alcohol consumption, chronic irritation, candidiasis, vitamin deficiency, endocrine disturbances, and possibly a virus. […] A definitive diagnosis of oral leukoplakia is made when any etiologic cause other than tobacco/areca nut use has been excluded and histopathology has not confirmed any other specific disorder.

    Leukoplakia is a descriptive term used to describe white plaques of questionable risk having excluded (other) known diseases or disorders that carry no increased risk for cancer affecting the oral mucosa. […] As leukoplakia is a descriptive term rather than a microscopic tissue diagnosis; a biopsy is mandatory to establish the diagnosis. The tissue diagnosis may range from benign (eg hyperkeratosis) to pre-malignant (dysplasia) to malignant (SCC). A recent systematic review showed that there was a malignant transformation rate of 0.1334% reported for oral leukoplakic lesions across 24 studies. […] It is therefore imperative that any leukoplakic lesion is referred for assessment and biopsy. […] Oral dysplasia is a histopathological diagnosis rather than a clinical descriptive term.

Any lesions with biopsy-proven dysplasia should be referred to an oral and maxillofacial surgeon or oral medicine specialist for appropriate management, which may vary depending on the patient, lesion extent and risk factors.
