Rak oka
Epidemiologia

Rak oka, stanowiący mniej niż 1% wszystkich nowotworów złośliwych, wykazuje zróżnicowaną epidemiologię zależną od regionu, wieku, płci i typu histologicznego. W USA prognozuje się w 2025 roku około 3140 nowych przypadków (1620 mężczyzn, 1520 kobiet) i 490 zgonów (270 mężczyzn, 220 kobiet), z dominacją czerniaka błony naczyniowej u dorosłych (5-7,5/milion) oraz siatkówczaka u dzieci (około 300 przypadków rocznie). W Wielkiej Brytanii częstość wynosi około 14,7/milion z rosnącym trendem o 30% od lat 90., a w Chinach i Tajwanie obserwuje się stabilne wskaźniki zachorowań, choć z rosnącą częstością chłoniaka ocznego. Czynniki ryzyka obejmują starszy wiek, płeć męską, jasną karnację, jasny kolor oczu oraz mutacje genetyczne (BAP1, GNAQ, GNA11). Przeżywalność 5-letnia dla czerniaka oka w USA wynosi 85% w stadium lokalnym, 67% regionalnym i 16% przy przerzutach, a dla siatkówczaka ogólnie 95%, z lepszym rokowaniem przy wczesnej diagnozie.

Epidemiologia raka oka

Rak oka stanowi rzadką grupę nowotworów, odpowiadającą za mniej niż 1% wszystkich nowych przypadków nowotworów złośliwych na świecie. Mimo rzadkiego występowania, nowotwory te stanowią istotne zagrożenie zarówno dla widzenia, jak i życia pacjentów.12 Epidemiologia raka oka różni się znacząco w zależności od regionu geograficznego, wieku pacjenta, pochodzenia etnicznego oraz typu histologicznego nowotworu.3

Zachorowalność na raka oka na świecie

W Stanach Zjednoczonych szacuje się, że w 2025 roku zostanie zdiagnozowanych około 3140 nowych przypadków raka oka i oczodołu (głównie czerniaków), w tym 1620 u mężczyzn i 1520 u kobiet. Przewiduje się, że w tym samym roku nowotwory te będą przyczyną około 490 zgonów (270 u mężczyzn i 220 u kobiet).4 W Wielkiej Brytanii odnotowuje się około 880 nowych przypadków raka oka rocznie, co stanowi ponad 2 nowe zachorowania dziennie.5

Globalnie częstość występowania raka oka wykazuje znaczne różnice geograficzne i etniczne. W Chinach średnia roczna częstość występowania raka oka wynosi 4,04 na 1 000 000 mieszkańców, raka powiek 6,30, a chłoniaka ocznego 1,89.6 W Tajwanie średnia roczna standaryzowana względem wieku częstość występowania nowotworów oka wynosi 2,46 na milion mieszkańców (2,57 dla mężczyzn i 2,33 dla kobiet).7 W Australii rocznie diagnozuje się około 125-150 przypadków czerniaka błony naczyniowej (5-6 przypadków na milion mieszkańców).8

W badaniu przeprowadzonym w Stanach Zjednoczonych częstość występowania wszystkich nowotworów oka wyniosła 37,3 na milion mieszkańców, raka płaskonabłonkowego spojówki 8,4 na milion, a innych nowotworów oka 28,9 na milion.9 W Kolumbii średnia roczna częstość występowania nowotworów oka wynosi 7,8 na milion dla mężczyzn i 6,9 na milion dla kobiet.10

Najczęstsze typy raka oka

Czerniak naczyniówki (czerniak błony naczyniowej, uveal melanoma) jest najczęstszym pierwotnym nowotworem złośliwym oka u dorosłych.11 W Stanach Zjednoczonych i Europie częstość występowania tego nowotworu wynosi około 5-7,5 przypadku na milion osób rocznie. Dla osób powyżej 50. roku życia wskaźnik zapadalności wzrasta do około 21 przypadków na milion rocznie.12

Siatkówczak (retinoblastoma) jest najczęstszym nowotworem oka u dzieci. W Stanach Zjednoczonych rocznie diagnozuje się około 300 nowych przypadków siatkówczaka, co stanowi około 3% wszystkich nowotworów dziecięcych. Choroba występuje najczęściej u dzieci poniżej 4 roku życia, a średni wiek w momencie diagnozy wynosi 18 miesięcy.13

Chłoniak oczny (ophthalmic lymphoma) stanowi trzeci najczęstszy typ raka oka. W badaniu przeprowadzonym w Chinach zaobserwowano rosnący trend zachorowań na chłoniaka ocznego, z rocznym przyrostem procentowym wynoszącym 2%.14

W chińskiej populacji rozkład najczęstszych typów histologicznych raka oka wygląda następująco: najczęstszym typem histologicznym dla raka oka jest chłoniak, a dla raka powiek – rak podstawnokomórkowy. Najczęstszym podtypem histologicznym chłoniaka ocznego jest pozawęzłowy chłoniak strefy brzeżnej z komórek B.15 Natomiast w Tajwanie, trzy najczęstsze nowotwory złośliwe oka to siatkówczak (35,3%), czerniak (17,9%) i chłoniak (13,8%).16

Czynniki ryzyka i predyspozycje

Najważniejsze czynniki ryzyka rozwoju raka oka obejmują:

  • Starszy wiek – wskaźniki zachorowalności na raka oka w Wielkiej Brytanii są najwyższe u osób w wieku 85-89 lat17
  • Płeć męska – częstość występowania wszystkich nowotworów oka jest związana z płcią męską i starszym wiekiem18
  • Jasna karnacja i jasny kolor oczu – czerniak oka jest znacznie częstszy u osób rasy białej niż u osób rasy czarnej19
  • Predyspozycje genetyczne – w tym mutacje genu BAP1, GNAQ i GNA1120

W przypadku czerniaka błony naczyniowej, osoby pochodzenia kaukaskiego, starsze, o jasnej skórze, która łatwo się opala, lub o jasnym kolorze oczu, mają większe ryzyko zachorowania.21 Czerniak oka występuje częściej u osób rasy białej i rzadziej w innych grupach rasowych.22

Dla wtórnych nowotworów oka, które powstają w wyniku przerzutów z innych części ciała, główne czynniki ryzyka są związane z pierwotnym nowotworem, najczęściej rakiem piersi, płuc lub przewodu pokarmowego.23

Trendy czasowe i prognozy

W Wielkiej Brytanii od wczesnych lat 90. XX wieku wskaźniki zachorowalności na raka oka wzrosły o prawie jedną trzecią (30%). Wskaźniki u kobiet wzrosły o ponad jedną czwartą (29%), a wskaźniki u mężczyzn wzrosły o ponad jedną czwartą (27%). W ciągu ostatniej dekady wskaźniki zachorowalności na raka oka wzrosły o prawie dwie piąte (37%).24

Przewiduje się, że wskaźniki zachorowalności na raka oka wzrosną o 50% w Wielkiej Brytanii między latami 2023-2025 a 2038-2040. Do lat 2038-2040 może być w Wielkiej Brytanii około 2100 nowych przypadków raka oka rocznie.2526

W Chinach częstość występowania raka oka pozostaje stabilna, natomiast obserwuje się wzrost zachorowań na raka powiek i chłoniaka ocznego.27 W Tajwanie trend czasowy częstości występowania nowotworów oka był stosunkowo stabilny w 18-letnim okresie, mimo istnienia rocznych wahań.28

Różnice geograficzne i etniczne

Częstość występowania czerniaka błony naczyniowej różni się znacząco w zależności od grupy etnicznej. W Stanach Zjednoczonych choroba występuje najczęściej u osób rasy białej pochodzenia nie-hiszpańskiego (6,02%), następnie u Latynosów (1,67%), Azjatów (0,38%) i Afroamerykanów (0,31%).29

W badaniu przeprowadzonym w Arabii Saudyjskiej stwierdzono, że częstość występowania raka oka wśród populacji saudyjskiej wynosiła od 0,2 do 0,3 na 100 000 mieszkańców, z wyjątkiem 2018 roku, kiedy to częstość występowania u mężczyzn osiągnęła szczyt 2,2 na 100 000. Badanie wykazało zróżnicowaną liczbę przypadków raka oka w poszczególnych regionach, przy czym w Rijadzie odnotowano najwyższą liczbę przypadków (35,39%), a następnie w Mekce (17,03%).30

W Brazylii, badania dotyczące czerniaka błony naczyniowej wykazały wyższą częstość występowania w południowych stanach kraju, z tendencją do wzrostu zapadalności. Badania sugerują jednak, że potrzebnych jest więcej danych do opracowania strategii lepszego zarządzania zdrowiem publicznym i zrozumienia epidemiologii tej choroby.31

Region Częstość występowania (na milion) Najczęstszy typ Trendy
USA 5-7,5 Czerniak naczyniówki (dorośli)
Siatkówczak (dzieci)
Stabilny
Wielka Brytania ~14,7 Czerniak naczyniówki Wzrost o 30% od lat 90.

Siatkówczak (21%) Wzrost tylko u mężczyzn
Arabia Saudyjska 2-3 (na 100 000) Siatkówczak Zróżnicowany

Przeżywalność i śmiertelność

Wskaźniki przeżywalności dla raka oka różnią się w zależności od typu nowotworu, stadium zaawansowania w momencie diagnozy oraz dostępnych metod leczenia.32 W Wielkiej Brytanii 6 na 10 (60%) osób z rozpoznaniem raka oka przeżywa dziesięć lat lub więcej.33

W Stanach Zjednoczonych, według bazy danych SEER (Surveillance, Epidemiology, and End Results) 5-letnie względne wskaźniki przeżycia dla czerniaka oka w latach 2012-2018 przedstawiały się następująco:34

  • Lokalny (ograniczony do oka) – 85%
  • Regionalny (ograniczony do oka i otaczających tkanek) – 67%
  • Odległy (rozprzestrzeniony do innych tkanek) – 16%
  • Wszystkie stadia – 81%

W przypadku czerniaka błony naczyniowej, około 50% pacjentów rozwinie przerzuty w ciągu 10-15 lat od diagnozy. Choroba przerzutowa jest niemal zawsze śmiertelna. Ten 50% wskaźnik śmiertelności pozostaje niezmieniony pomimo postępów w leczeniu pierwotnego guza oka.35

Dla siatkówczaka, ogólny wskaźnik przeżycia dla dzieci wynosi 95%. Rokowanie jest najlepsze przy diagnozie przed 2 rokiem życia.36 Jednak u osób z dziedziczną postacią siatkówczaka występuje zwiększone ryzyko rozwoju wtórnych nowotworów w ciągu życia.37

W Kanadzie, według najnowszych statystyk śmiertelności z 2022 roku, 52 Kanadyjczyków zmarło z powodu raka oka, w tym 21 mężczyzn i 31 kobiet.38 W Brazylii w latach 2010-2019 odnotowano 1859 zgonów z powodu złośliwego nowotworu oka i przydatków oka, co dotyczyło 1062 (57,1%) mężczyzn.39

Nadzór i obserwacja raka oka

Nadzór nad rakiem oka obejmuje zarówno monitorowanie występowania nowych przypadków w populacji (nadzór epidemiologiczny), jak i obserwację pacjentów z już zdiagnozowanym nowotworem oka (aktywny nadzór medyczny).40

Nadzór epidemiologiczny

Systemy nadzoru epidemiologicznego dla raka oka obejmują rejestry nowotworów, które zbierają dane dotyczące częstości występowania, typów histologicznych, czynników ryzyka i wyników leczenia. Do najważniejszych systemów nadzoru należą:

  • Program SEER (Surveillance, Epidemiology, and End Results) Narodowego Instytutu Raka w USA, który jest jedynym kompleksowym źródłem informacji o nowotworach opartym na populacji w Stanach Zjednoczonych, które uwzględnia stadium nowotworu w momencie diagnozy i wskaźniki przeżycia w każdym stadium.41
  • Centrum Epidemiologii Oka UCLA (UCLA Center for Eye Epidemiology), które zostało założone w 1997 roku w celu promowania interdyscyplinarnych badań dotyczących chorób oczu o znaczeniu dla zdrowia publicznego.42
  • System danych MDCSS (Metropolitan Detroit Cancer Surveillance System), który zawiera informacje o wszystkich diagnozach nowotworów i przeżyciu dla obszaru metropolitalnego Detroit od 1973 roku.43

W kontekście rzadkich nowotworów, takich jak rak oka, systemy nadzoru epidemiologicznego napotykają na wyzwania związane z dokładnością zbierania danych. Na przykład, algorytm definicji przypadku raka publikowany przez Armed Forces Health Surveillance Branch miał wysoką wartość predykcyjną dodatnią (PPV) dla częstych nowotworów, ale niską do umiarkowanej PPV dla rzadszych nowotworów.4445

Aktywny nadzór medyczny

Aktywny nadzór, znany również jako uważna obserwacja, jest strategią postępowania medycznego polegającą na regularnym monitorowaniu pacjentów z rozpoznanym rakiem oka, którzy nie mają objawów, zamiast natychmiastowego wdrażania leczenia. Ta metoda pozwala uniknąć problemów lub skutków ubocznych, które mogą wystąpić przy leczeniu chirurgicznym lub radioterapii.46

Aktywna obserwacja może być zalecana w następujących przypadkach:47

  • Guz jest mały, nie powoduje żadnych objawów i nie rozprzestrzenił się poza oko
  • Guz rośnie bardzo powoli
  • Guz znajduje się w jedynym oku z użytecznym widzeniem
  • Pacjent jest starszy lub bardzo chory, co może utrudniać radzenie sobie z leczeniem

Dla pacjentów z czerniakiem błony naczyniowej istnieje konsensus wspierający koncepcję prowadzenia nadzoru ze szczególnym uwzględnieniem badań przesiewowych wątroby. Zaleca się, aby wszyscy pacjenci, niezależnie od ryzyka, mieli przeprowadzoną całościową ocenę w celu omówienia ryzyka, korzyści i konsekwencji włączenia do programu nadzoru.48

Szkocki konsensus dotyczący metastatycznego nadzoru czerniaka błony naczyniowej zaleca stratyfikowane podejście do nadzoru dla tych pacjentów, dzieląc ich na grupy niskiego do średniego ryzyka i wysokiego ryzyka, definiując tryb i czas trwania nadzoru dla każdej z nich.49

Trwający nadzór nad czerniakiem błony naczyniowej obejmuje harmonogram badań i skanów, badań oka i badań fizykalnych.50

Wyzwania w nadzorze raka oka

Nadzór nad rakiem oka stwarza specyficzne wyzwania ze względu na rzadkość występowania tej choroby oraz różnorodność typów histologicznych. Jednym z głównych wyzwań jest identyfikacja skupisk przypadków (klastrów) raka oka.51

Na przykład, w 2018 roku urzędnicy ds. zdrowia z Alabamy ogłosili, że badanie nie znalazło dowodów na istnienie skupiska czerniaka błony naczyniowej na Uniwersytecie Auburn, pomimo serii zgłoszonych przypadków tego rzadkiego i śmiertelnego nowotworu. Departament Zdrowia Publicznego Alabamy stwierdził, że badanie „oparte na najlepszych dostępnych informacjach” nie wykazało wyższych niż oczekiwane wskaźników czerniaka błony naczyniowej wśród byłych studentów i pracowników uniwersytetu.52

Innym wyzwaniem jest brak jednolitego podejścia do nadzoru na całym świecie. Nie ma konsensusu dotyczącego sposobu, częstotliwości, czasu trwania lub użyteczności regularnego nadzoru wątroby w kierunku przerzutów, a opublikowane protokoły nie istnieją.53

W przypadku siatkówczaka, nowoczesne badania wykazały, że skrócenie czasu od pierwszego pojawienia się objawów do diagnozy nie ma wpływu na przeżycie lub stadium choroby w jednostronnym siatkówczaku, najczęstszej postaci raka oka u dzieci. Badanie sugeruje, że badania przesiewowe dzieci w kierunku siatkówczaka mogą nie poprawiać wyników dla większości pacjentów, szczególnie dla częstszej postaci choroby dotyczącej jednego oka.54

Znaczenie badań epidemiologicznych dla nadzoru raka oka

Badania epidemiologiczne odgrywają kluczową rolę w identyfikacji czynników ryzyka i określeniu strategii zapobiegania rakowi oka. Jednym z obszarów badań jest związek między promieniowaniem UV a ryzykiem rozwoju nowotworów oka.55

W dużym badaniu rejestrów nowotworów w USA, analizującym dane z lat 2000-2019, stwierdzono, że promieniowanie UV nie było związane z całkowitym czerniakiem oka (N=18,089), ale w analizach ciągłego promieniowania UV ryzyko było zmniejszone dla całkowitego czerniaka oka. Jednak częstość występowania była zwiększona dla czerniaka ciała rzęskowego/tęczówki w najwyższym kwartylu promieniowania UV i pozostała zwiększona tylko u osób rasy białej pochodzenia nie-hiszpańskiego.56

Badanie to nie potwierdza promieniowania UV jako czynnika ryzyka całkowitego czerniaka oka. Według lokalizacji anatomicznej stwierdzono, że promieniowanie UV jest związane ze zwiększonym ryzykiem czerniaka ciała rzęskowego/tęczówki, ale ze zmniejszonym ryzykiem czerniaka naczyniówki.57

Inne badanie wykazało, że rak oka występuje częściej u mężczyzn, osób starszych i mieszkających na niższych szerokościach geograficznych lub na obszarach o wysokiej ekspozycji rumieniowej, co może być związane z ekspozycją na promieniowanie ultrafioletowe.58

Zrozumienie wzorców i częstości występowania raka oka w różnych regionach i grupach wiekowych może pomóc władzom opieki zdrowotnej i decydentom w opracowaniu ukierunkowanych strategii zapobiegania, wczesnego wykrywania i leczenia tego schorzenia.59

    Primary eye cancer is a very rare kind of cancer that starts somewhere in or on the eye or in the skin of cells around the eye. It most often starts inside the eyeball itself. This is called primary intraocular cancer. Because its so rare, its best to seek treatment from an eye cancer specialist. […] The risk factors for eye cancer include: White skin, Light-colored eyes, Older age, Being a man, Having many abnormal moles (dysplastic nevus syndrome), Abnormal brown spots on the uvea (oculodermal melanocytosis or nevus of Ota), BAP1 cancer syndrome. […] Theres no known way to prevent eye cancer. […] There are no regular screening tests for eye cancer in people at average risk. Screening is done to check for disease in people who dont have symptoms. […] Your eye care provider (ophthalmologist) should check for signs of cancer during regular eye exams.

    https://www.cancerresearchuk.org/health-professional/cancer-statistics/statistics-by-cancer-type/eye-cancer/incidence
    Eye cancer is not among the 20 most common cancers in the UK, accounting for less than 1% of all new cancer cases (2017-2019). […] For eye cancer, there are few established risk factors therefore differences between countries largely reflect differences in diagnosis and data recording. […] Eye cancer European age-standardised (AS) incidence rates for females and males combined increased by 30% in the UK between 1993-1995 and 2017-2019. […] For eye cancer there are few established risk factors, therefore increasing incidence in the 1980s and 1990s may largely reflect improvements in diagnosis and data recording. […] The number of new eye cancer cases on average each year in the UK is projected to rise from around 1,300 cases in 2023-2025 to around 2,100 cases in 2038-2040. […] Eye cancer incidence rates are projected to rise by 50% in the UK between 2023-2025 and 2038-2040, to 3 cases per 100,000 people on average each year by 2038-2040.

    https://www.cancer.org/cancer/types/eye-cancer/about/key-statistics.html
    The American Cancer Societys estimates for primary eye cancer (cancer that starts in the eye) in the United States for 2025 are: […] About 3,140 new cancers (mainly melanomas) of the eye and orbit (eye socket) (1,620 in males and 1,520 in females) […] About 490 deaths from cancers of the eye and orbit (270 in males and 220 in females) […] Primary eye cancers can occur at any age, but some types are more likely during childhood, while others are more common in adults. […] Retinoblastomas and medulloepitheliomas usually develop in young children, but the risk for most other types of eye cancer increases as people get older. […] Melanoma is the most common cancer of the eye and orbit in adults, but most melanomas (more than 9 out of 10) start in the skin. Melanoma of the eye is much more common in White people than in Black people. […] Secondary eye cancers (cancers that start in another part of the body and then spread to the eye) are actually more common than primary eye cancers.

    Purpose: To investigate the risk factors for squamous-cell carcinoma of the conjunctiva (SCCC) and other eye cancers in the NIH-AARP Diet and Health Study. […] The incidence was 37.3 per 106 for all eye cancers (N = 178), 8.4 per 106 for SCCC (N = 40) and 28.9 per 106 for other eye cancers (N = 138). […] The incidence of all eye cancers was associated with male sex and older age. The same patterns were observed for SCCC. […] To conclude, eye cancers including SCCC are rare with incidence associated with males, older age and residing at lower latitude or high erythemal exposures areas complementary to previous studies. These characteristics might be surrogates of exposure to ultraviolet radiation.
  • #10 Epidemiology of ocular cancer in Cali | Eye News
    https://www.eyenews.uk.com/reviews/journal-reviews/post/epidemiology-of-ocular-cancer-in-cali
    The aim of this study was to describe the population trends of incidence and survival rates of ocular cancer in Cali, Columbia. […] Between 1962 and 2019, 586 ocular tumours were registered in Cali, of which 81.7% were histologically confirmed which is comparable to studies based in Taiwan and New York. […] The average annual incidence rate was 7.8 per million for males and 6.9 per million for females. […] A significant increase in the incidence was only noted for men (annual percentage change (APC) 2.8, 95% CI=0.94.7). […] Age-standardised incidence increased over time for the whole population (APC 1.9, 95% CI=0.63.2, p0.05), possibly associated with the advent of new and improved technologies for diagnosis of ocular tumours. […] Retinoblastoma (21%) was the most common neoplasm, and remains a relevant public health issue, with an incidence twice that seen in the US. […] The survival rate was about 83.2% and mortality did not show a decreasing trend over time (p0.05).

    Epidemiological data is critical for planning early treatment strategies and allocating medical resources. This study intended to understand the characteristics of uveal melanoma in Brazil. […] Uveal melanoma is the most common primary intraocular malignancy and represents approximately 5% of all melanoma cases. […] A heterogeneous incidence of 4.3 to 10.6 cases of uveal melanoma per million of people is verified each year globally depending on the studied population, inclusion criteria and methodology used for the study. […] Epidemiological studies in the Brazilian population are mostly related with skin melanoma and mucosal melanoma and data for uveal melanomas are scarce and inconsistent. […] Higher incidence is observed in the southern states of Brazil and a trend for increased incidence is observed but studies suggest more data is necessary for tracing strategies for better public health management and understanding the epidemiology of the disease.
  • #12 OMF | Ocular Melanoma Foundation – disease
    https://ocularmelanoma.org/disease
    Ocular melanoma is the most common primary cancer of the eye in adults. It is diagnosed in about 2,500 adults every year in the United States and occurs most often in lightly pigmented individuals with a median age of 55 years. […] Ocular melanoma (OM for short) is a cancer of the eye diagnosed in approximately 2,000-2,500 adults annually in the United States. In both the U.S. and Europe, this equates to about 5 – 7.5 cases per million people per year and, for people over 50 years old, the incidence rate increases to around 21 per million per year. […] Approximately 2,500 adults are diagnosed with ocular melanoma every year. There is no known cause, though incidence is highest among people with lighter skin and blue eyes. […] Approximately 50% of patients with OM will develop metastases by 10 to 15 years after diagnosis (a small percentage of people will develop metastases even later i.e. 20-25 years after their initial diagnosis). Metastatic disease is universally fatal. This 50% mortality rate is unchanged despite treatment advances in treating the primary eye tumor. More research is needed urgently to improve patient outcomes.

    https://www.chop.edu/conditions-diseases/retinoblastoma
    Retinoblastoma is a rare eye cancer found in children. It originates in the part of the eye called the retina. About 300 children are diagnosed with retinoblastoma in the United States each year. The disease occurs most often in children younger than 4 years old, and accounts for about 3 percent of all cancers in children from birth to 14 years old. The average age of children diagnosed with retinoblastoma is 18 months old and boys and girls are affected equally. […] The diagnosis of retinoblastoma is made by examining the eyes. If your baby has a family history of retinoblastoma, your baby should be examined shortly after birth by an ophthalmologist (medical eye doctor) who specializes in cancers of the eye. […] After a retinoblastoma has been detected, the doctor will determine the extent of the disease in the eye and if the disease has spread (metastasized) outside the eye. This is called staging, and it helps doctors plan treatment.

For the year 2020, the estimated number of new cases in the United States were 3400 cases (males: 1890 cases; females: 1510 cases) and the estimated mortality was 390 deaths (males: 210 deaths; females: 180 deaths). Eye cancer was slightly more predominant in males (53%) when compared to the females (47%). Based on the anatomic site, retinoblastoma and uveal melanoma are the most frequent types of eye cancer. Retinoblastoma contributes to nearly 4% of all the pediatric cancers. Incidence rate in children was 1 in 15,000-18,000 per year worldwide. Global incidence of the retinoblastoma is 9000 new cases per year. Each year, about 300 new retinoblastoma cases are reported in the United States. The incidence of retinoblastoma is equal in boys and girls. The 5-year survival rate of retinoblastoma was 96% in children. For retinoblastoma, the median age of diagnosis was 15 and 24 months for hereditary and sporadic forms, respectively. The incidence rate was higher in the regions of Southeast Asia and South America. The other common type of intraocular cancer is Uveal melanoma (UM), which is usually seen in adults. Uveal melanoma occurs in the uveal tract accounting to 85% of all ocular melanomas. The incidence rate was 4.3% in the United States (male: 4.9%; female: 3.7%). The incidence rate differs for different ethnic groups, mostly occurring in non-Hispanic whites (6.02%) followed by Hispanics (1.67%), Asians (0.38%), and Afro-Americans (0.31%). The median age of Uveal melanoma (UM) diagnosis in the US and Europe is 59-62 years. The mean age-adjusted annual incidence of UM is 5.1 cases per million. UM has an annual incidence of 5 per million; 650 new cases of UM were diagnosed and treated every year.

    Ophthalmic treatments are successful in managing uveal melanomas achieving good local control. However, a large number still metastasise, primarily to the liver, resulting in mortality. There is no consensus across the world on the mode, frequency, duration or utility of regular liver surveillance for metastasis and there are no published protocols. […] The consensus statement recommends a risk-stratified approach to surveillance for these patients dividing them into low to medium-risk and high-risk groups defining the mode and duration of surveillance for each. It supplements the UK-wide Uveal Melanoma National Guidelines and allows a more uniform consensus-based approach to surveillance in Scotland.

    If you have eye cancer but dont have any symptoms, you may be offered active surveillance (watchful waiting). This means that your healthcare team watches your cancer closely rather than giving treatment right away. They will use tests and exams to check if the tumour starts to grow. Treatment is given when you develop symptoms or the cancer changes. […] This approach helps avoid problems or side effects that can happen with treatments such as surgery or radiation therapy. There is no evidence so far that people wont live as long when they get active surveillance compared to other treatments. And there is no evidence that active surveillance has other negative effects if or when you start treatment. […] You may be offered active surveillance if: the tumour is small, is not causing any symptoms and hasnt spread outside of the eye; the tumour is growing very slowly; the tumour is in the only eye with useful vision; you are older or very ill, which may make it hard to cope with treatment.

    Public health officials are investigating a medical mystery that has spanned nearly two decades in Auburn, Alabama and Huntersville, North Carolina. Over 50 people in the two cities have been diagnosed with ocular melanoma, a rare form of eye cancer, since 1999. Ocular melanoma ordinarily has an incidence of 6 cases per 1 million people, so the diagnosis of at least 50 cases in just two locations is exceedingly unusual. […] Researchers, including epidemiologists at the Alabama Department of Public Health, are trying to determine why so many people linked to Auburn and Huntersville have developed ocular melanoma. The group of cases is not yet being defined as a cancer cluster. […] A previous report, released in June 2015 from the North Carolina Department of Health and Human Services, details the results of one investigation into the potential cancer cluster in Huntersville. The researchers determined that ocular melanoma cases diagnosed between the years 2009 and 2014 did not constitute a significantly above-average caseload, but they did point to excessive exposure to UV radiation as a risk factor for many of the patients included in the study.

    MONTGOMERY Alabama health officials announced this week that a study did not find evidence of an eye cancer cluster at Auburn University, despite a rash of reported cases of the rare and deadly cancer that drew national attention earlier this year. […] The Alabama Department of Public Health said the study „based on the best available information” did not find higher than expected rates of uveal melanoma among former students and university employees. […] Justin T. George, director of cancer epidemiology, said the study looked at identified cases among people who attended or worked at Auburn since 1980. […] From 2006 through 2015, there were 316 cases of uveal melanoma among Alabama residents for an average of 31.6 new cases each year, the department said. […] A limitation of the Auburn study is that cancer registries across the country do not capture where a person attended college. […] George said researchers remain comfortable in the finding. He said the cancer would have to occur in substantially higher numbers to qualify as a cluster.

    Shortening the time from first appearance of symptoms to diagnosis has no bearing on survival or stage of disease in unilateral retinoblastoma, the most common form of childhood eye cancer, according to a new study. […] Our study suggests that screening children for retinoblastoma may not improve outcomes for the majority of patients, particularly for the more common form of the disease affecting one eye, said senior author Manuela A. Orjuela, MD, ScM, of Columbia University. […] The researchers found that for unilateral disease, the lag-time between when parents first noticed the disease and when the children were diagnosed had no bearing on disease stage or survival. […] There is also significant variation in how tumors respond to treatment, no matter how soon we initiate therapy, said first author Marco A. Ramrez-Ortiz, MD, chief of the department of Ophthalmology at the Hospital Infantil de Mxico. […] Intriguingly, the researchers found that stage and survival in both forms of retinoblastoma were predicted by the mothers education level. Mothers with less formal schooling had children with significantly higher stage disease and significantly worse survival.

It is the most common primary tumor of the eye in adults (Shields 1983). The incidence of IMM has been studied in descriptive studies of populations and in case reports of individuals and families. Because of the rarity of the disease, few analytic studies have been undertaken.

    https://www.nature.com/articles/s41433-024-02959-9
    Ocular melanoma is a rare, but deadly cancer. This large cancer registry study examines the associations between solar ultraviolet radiation (UVR) and incidence of different anatomical sites of ocular melanoma by sex, age, laterality, and race and ethnicity. […] Incidence data were derived from 21 cancer registries in the US for the years 20002019. […] UVR was not associated with total ocular melanoma (N=18,089) comparing Q4 versus Q1 (IRR=0.98; 95%CI:0.94,1.03; p-trend=0.07) or conjunctival melanoma (IRR=0.99; 95%CI:0.82,1.19; p-trend=0.81). However, in analyses of continuous UVR (per 10mW/m2), risks were reduced for total ocular melanoma (IRR=0.97; 95% CI: 0.96, 0.99). […] Incidence was increased for ciliary body/iris melanoma in the highest UVR quartile (IRR=1.63; 95%CI:1.43,1.87; p-trend0.0001) and remained increased in non-Hispanic White individuals only.

    Our results support and expand previous findings of associations of UVR using various surrogates on ocular melanoma risk and serve as a starting point for understanding the differences in the relationship between UVR and specific anatomical sites. […] Ocular melanoma is diagnosed in about 2000 new patients in the United States each year. […] Possible risk factors of ocular melanoma (mainly focused on uveal melanoma) include male sex, older age, light eye colour, sun-sensitive skin, higher numbers of cutaneous melanocytic nevi, ocular melanocytosis, ubiquitin carboxyl-terminal hydrolase BAP1 germline mutations, and exposure to ultraviolet radiation (UVR). […] Epidemiological studies on the relationship between solar UVR and risk of ocular melanoma have been inconsistent. […] Our study may strengthen an etiological role of UVR in ciliary body/iris melanoma. However, this harmful association was not consistent with Vajdic et al. that found no association between several surrogates (e.g., latitude, occupational and recreational sun exposures, lifetime modelled ambient UVR, and eye protection) of UVR and risks of iris melanoma. […] In summary, this U.S. cancer registry study does not support UVR as a risk factor of total ocular melanoma. By anatomical sites, we found UVR to be associated with an increased risk of ciliary body/iris melanoma, but a reduced risk of choroidal melanoma.

    Purpose: To investigate the risk factors for squamous-cell carcinoma of the conjunctiva (SCCC) and other eye cancers in the NIH-AARP Diet and Health Study. […] The incidence was 37.3 per 106 for all eye cancers (N = 178), 8.4 per 106 for SCCC (N = 40) and 28.9 per 106 for other eye cancers (N = 138). […] The incidence of all eye cancers was associated with male sex and older age. The same patterns were observed for SCCC. […] To conclude, eye cancers including SCCC are rare with incidence associated with males, older age and residing at lower latitude or high erythemal exposures areas complementary to previous studies. These characteristics might be surrogates of exposure to ultraviolet radiation.

    The predominance of squamous cell carcinoma in the other studies could be attributed to the overexposure to excessive sunlight in Africa. This is not the cases among Saudi, due to cultural and religious issue females cover their body and face reducing the body area exposed to the sun. […] Ocular cancer incidences in Saudi Arabia have drastically varied throughout the countrys various regions and age categories from 1998 to 2018, according to data on the disease. The highest incidence is observed in Riyadh, followed by Makkah, while certain regions have lower rates. Additionally, the incidence of ocular cancer varies among different age groups, with the highest occurrence in the 0-4 age group. The study also highlights fluctuations in the annual number of reported cases, suggesting potential influences from various factors. Furthermore, there are variations in the gender and nationality distribution among reported cases over the years. Overall, the study emphasizes the need for continued monitoring, research, and analysis of potential factors influencing ocular cancer occurrence in Saudi Arabia. Understanding the patterns and prevalence of ocular cancer in different regions and age groups can help healthcare authorities and policymakers devise targeted strategies for prevention, early detection, and treatment of this condition.
