RESUMO

INTRODUCTION: Intra-arterial chemotherapy (IAC) is useful for eye preservation in advanced retinoblastoma (Rb). Intra-vitreal chemotherapy (IvitC) is the latest treatment for vitreous seeds. METHODS: The present study is a retrospective assessment of 100 eyes, treated with primary or secondary IAC alone or with IvitC. We evaluated demographic and clinical variables, eye salvage, associated adverse events, and patient survival. Data were analyzed using descriptive statistics. Kaplan-Meier survival curves and Cox hazard ratios were utilized to assess the effect of demographic and clinical variables over eye salvage. RESULTS: Bilateral Rb was observed in 61% of patients, and 57% of eyes received secondary treatment. Forty eyes needed intra-arterial plus IvitC and 62 presented advanced disease (group D and E). Three- and 5-year ocular survival probabilities were 75 and 68%. We found a higher risk in group D and E eyes and those requiring 2 or more routes for ophthalmic artery catheterization. Patients coming from other countries also showed increased risk. Using primary or secondary treatment, or IvitC, did not affect this risk. Overall rates of survival and eye salvages were 98.8 and 73%, and we had a 100% catheterization success and none ophthalmic arterial occlusions. CONCLUSIONS: In an upper middle-income country such as Colombia, a specialized institution counting with therapeutic alternatives and a multidisciplinary team can reach rates of patient survival and eye salvage similar to those of high-income countries.

RESUMO

Objetivo: Describir las características clinicopatológicas de los pacientes con diagnóstico de melanoma de la úvea. Métodos: Se realizó un estudio descriptivo y retrospectivo de serie de casos, en el Instituto Cubano de Oncología y Radiobiología de Cuba, desde enero del año 2011 hasta junio de 2016. El universo del estudio, en coincidencia con la muestra, estuvo constituido por 41 pacientes, el total de ellos diagnosticado y tratado en dicho período por melanoma uveal. Se estudiaron las variables edad, sexo, lateralidad, localización y tamaño tumoral, clasificación, tipo celular, grado de invasión y tratamiento. Resultados: El 56,1 por ciento de la muestra fue del sexo femenino. Los pacientes mayores de 50 años (75,6 por ciento) fueron los más afectados y el ojo izquierdo fue el más vulnerable (58,5 por ciento). La principal localización fue en la coroides (75,6 por ciento). Según el tamaño tumoral predominaron los tumores grandes (58,5 por ciento); histológicamente el tipo celular más frecuente fue el de células fusiformes (34,2 por ciento); según el grado de invasión, la más afectada fue la esclera (17,0 por ciento) y como único tratamiento practicado la enucleación (100 por ciento). Conclusiones: El melanoma de la úvea tiene su localización más frecuente en la coroides. Se presenta principalmente en pacientes mayores de 50 años y predominan los tumores grandes(AU)


Objective: To describe the clinical and pathological characteristics of patients diagnosed with uveal melanoma. Methods: A retrospective, descriptive and case series study was performed from January 2011 to June 2016 in the Institute of Oncology and Radiobiology of Cuba (INOR). The universe of study was the sample of 41 patients, all of them diagnosed with uveal melanoma and treated in this period of time. The study variables were age, sex, laterality, tumor location and tumor, classification, cell type, degree of invasion and treatment. Results: Females accounted for 56.1 percent of the sample. The patients aged 50 years or over (75.6 percent) were the most affected whereas left eye was the most vulnerable (58.5 percent). The main location were the choroids (75.6 percent) According to size, the large tumors predominated (58.5 percent); from the histological viewpoint, the most common cell-type was fusiform cell tumor (34.2 percent); according to the degree of invasion, the sclera was the most affected (17 percent) and the only treatment was enucleation. Conclusions: Uveal melanoma is more frequently located in the choroids. It mainly appears in patients aged over 50 years and most of tumors are large(AU)

RESUMO

El melanoma maligno de coroides es el tumor intraocular primario más frecuente en la edad adulta. Su evolución clínica es muy variable y constituye un peligro potencial para la vida de las personas afectadas. Se presenta el caso de un paciente de 42 años, caucásico, de procedencia urbana que acudió al Centro Oftalmológico de Holguín por disminución lenta y progresiva de la visión de aproximadamente hacía dos años de evolución que inicialmente comenzó como un defecto del campo visual periférico hasta afectar la visión central. La oftalmoscopía mostró lesión tumoral yuxtapapilar de coloración pardo-grisácea, elevada en forma de hongo, que produjo desprendimiento de retina secundario en tienda de campaña. Fue diagnosticado como portador de un melanoma maligno de coroides y remitido al Instituto Nacional de Oncología y Radiobiología donde se le realizó la enucleación del ojo derecho y se confirmó el diagnóstico por anatomía patológica. Se discutieron los principales factores de riesgo, la forma clínica de presentación, los hallazgos en las investigaciones clínicas realizadas para el diagnóstico, la modalidad de tratamiento aplicada, la evolución y el pronóstico, a partir de la información recogida de la revisión del expediente clínico del paciente.


Choroidal malignant melanoma is the most frequent intraocular tumor in adults. Its clinical evolution is very variable and it is a potential hazard for the life of the affected people. The case of a 42-year-old Caucasian urban male patient is reported. The patient presented to the Ophthalmological Center of Holguín complaining of slow and progressive loss of vision of about 2-years´ evolution that initially began as a peripheral visual field defect up to affect central vision. The ophthalmoscopy showed an elevated grayish-brown-colored mushroom-shaped tumoral lesion next to the papilla that produced a secondary tent-like retinal detachment. He was diagnosed as carrier of choroidal malignant melanoma and was referred to The National Institute of Oncology and Radiobiology where the enucleation of his righ eye ball was performed and the diagnosis was confirmed through pathological study. The main risk factors, clinical presentation, clinical research findings for diagnosis, treatment, evolution and prognosis were discussed from the information obtained from his clinical record.
