ABSTRACT

PURPOSE: Determine whether cytopathologic classification of melanocytic uveal tumors evaluated by fine-needle aspiration biopsy (FNAB) is a significant prognostic factor for death from metastasis. METHODS: Retrospective analysis of cases of clinically diagnosed uveal melanoma evaluated by fine-needle aspiration biopsy from 1980 to 2006. Main outcome evaluated was death from metastasis. Associations between baseline clinical variables and cytopathologic classification were evaluated using cross-tabulation. Prognostic significance of cytopathologic classification was evaluated by Kaplan-Meier and Cox proportional hazards analysis. RESULTS: Of 302 studied biopsies, 260 (86.1%) yielded sufficient cells for cytopathologic classification. Eighty of the 260 patients who had a sufficient specimen have already died (P=0.021), 69 from metastatic uveal melanoma. Cell type assigned by cytopathology was strongly associated with metastasis/metastatic death in this series (P=0.0048). Multivariate analysis showed cytopathologic classification to be an independently significant prognostic factor for metastatic death (P=0.0006). None of the 42 patients whose tumor yielded insufficient aspirates (sampled in at least two sites) have developed metastasis or died of metastasis thus far. CONCLUSION: In this series, cytopathology of fine-needle aspiration biopsy samples obtained from uveal melanomas was strongly prognostic of death from metastasis. Insufficiently aspirates (2 or more sites sampled) proved to be prognostic of a favorable outcome (i.e., not developing metastasis).


OBJETIVO: Determinar se a classificação citopatológica de tumores melanocíticos da úvea avaliados pela biópsia aspirativa com agulha fina (BAAF) é um fator prognóstico significativo para óbito por metástases. Métodos: Análise retrospectiva de casos diagnosticados clinicamente como melanoma uveal e avaliados pela biópsia aspirativa com agulha fina entre 1980 e 2006. O evento principal analisado foi óbito por metástase. Associações entre variáveis clínicas à apresentação e classificação citopatológica foram avaliadas usando tabulação cruzada. Significância prognóstica da classificação citopatológica foi avaliada por análise de riscos proporcionais de Cox e Kaplan-Meier. RESULTADOS: Das 302 biópsias estudadas, 260 (86,1%) renderam um número suficiente de células para classificação citopatológica. Oitenta dos 260 pacientes que obtiveram um espécime suficiente (adequado) foram a óbito (P=0,021), 69 destes por melanoma uveal metastático. O tipo celular designado pela citopatologia apresentou forte associação com metástase/óbito por metástase nessa série (P=0,0048). Análise multivariada mostrou que a classificação citopatológica foi um fator prognóstico independente significativo para o óbito por metástase (P=0,0006). Nenhum dos 42 pacientes cujos tumores renderam um aspirado insuficiente (quando foram amostrados pelo menos 2 sítios) desenvolveu metástase e foi a óbito por metástase até o presente momento. CONCLUSÃO: Nessa série, a citopatologia dos espécimes obtidos pela biópsia aspirativa com agulha fina de melanomas uveais foi fortemente prognóstica para óbito por metástase. Os aspirados insuficientes (se duas ou mais áreas foram amostradas) provou ser um resultado prognóstico favorável (i.e., de não desenvolvimento de metástases).

ABSTRACT

PURPOSE: To study the clinical and histopathological characteristics of uveal melanomas in Asian Indians and compare them with other ethnic groups. MATERIALS AND METHODS: One hundred and three enucleated eyes with clinical diagnosis of uveal melanoma were retrospectively studied (1987-2001) and the clinical and pathological features analysed. RESULTS: Uveal melanomas constituted 0.02% of outpatients in a referral eye hospital in India over a 12-year period. The patients were predominantly males. Uveal melanomas tended to occur in the younger age. The mean age was 45.7 +/- 14.2 years. Melanoma involved the choroid in 90 (87.37%) patients, and both choroid and ciliary body in 13 (12.62%) patients. Mean basal diameter of the tumour was 13.43 +/- 5.32 mm. Mixed cell type was more common. CONCLUSION: Uveal melanomas are rare in the Asian Indians compared to those in the West. They occur in younger persons, have a greater mean basal diameter than that of Caucasians and are predominantly of the mixed cell type.

ABSTRACT

Este estudio es un análisis de los factores de riesgo en la sobrevida de pacientes por melanoma uveal en Chile durante el período de 1979 a 1989. Se analizaron 74 pacientes enucleados por melanoma uveal identificados en el laboratorio ocular del Hospital Clínico de la Universidad de Chile. Para determinar su estado vital al momento del estudio de obtuvo información de las fichas del hospital, informes de los médicos tratantes e informe oficial del Registro Civil e Identificación según el RUT del paciente. Los factores de riesgo considerados fueron la edad del paciente, localización del borde anterior del tumor, tipo histológico, radioterapia previa, invasión escleral y altura del tumor. Para el análisis de los datos se trabajó con el programa Epi Info. Se determinaron dos grupos de riesgo: riesgo alto de mortalidad (60 años de edad o más, al borde anterior del tumor preecuatorial y tipo celular epiteloídeo) y bajo riesgo de mortalidad (menos de 60 años de edad, borde anterior del tumor postecuatorial y tipo celular no epiteloídeo)
