Metástasis intraoculares: comparación entre las formas de presentación clínica con tumor primario conocido y desconocido / Intraocular metastasis: comparison of clinical presentation with a known and unknown primary tumour

OBJETIVO: El objetivo del presente estudio es revisar la frecuencia de metástasis intraoculares como primera manifestación de enfermedad sistémica e identificar las características clínicas y tumorales. MÉTODOS: Estudio retrospectivo y consecutivo de casos diagnosticados como metástasis intraoculares en una unidad de referencia de tumores intraoculares entre 1993 y 2014. Se registraron las características generales, epidemiológicas y oftalmológicas. RESULTADOS: Entre 1993 y 2014, se diagnosticaron 21 pacientes con metástasis intraoculares. Edad media de 62,7 años (31-89). Se observó bilateralidad en 4 casos y localización coroidea en 20 casos. El tumor intraocular fue la primera manifestación de la enfermedad sistémica en 13 pacientes (61,9%). El tumor primario fue la mama en el 47,5% de los casos y el pulmón en el 23,8%. El diagnóstico del tumor primario se realizó mediante estudios sistémicos y solo un paciente requirió biopsia intraocular. Respecto al tratamiento, la mayoría de los casos se controlaron mediante terapia sistémica; 4 casos precisaron radioterapia externa adicional y solamente un caso, enucleación. No se encontraron diferencias clínicas entre los casos de cáncer sistémico conocido o desconocido, excepto respecto al desprendimiento de retina exudativo, más frecuente en el segundo grupo. CONCLUSIONES: Aunque las metástasis intraoculares son el tumor intraocular más frecuente, no son un motivo frecuente de consulta. En más de la mitad de los casos es la forma de presentación de una neoplasia sistémica desconocida como una masa intraocular solitaria no pigmentada. El diagnóstico precoz es crucial para establecer el tratamiento adecuado, preservar la función visual y mejorar el pronóstico vital del paciente

OBJECTIVE: The purpose of the present study is to review the frequency of intraocular metastases as first presentation of systemic disease, and to identify clinical and tumour characteristics. METHODS: Retrospective study of consecutive cases diagnosed of intraocular metástasis at a referral intraocular tumours unit between 1993 and 2014. General, epidemiological and ophthalmological characteristics were recorded. RESULTS: A total of 21 patients, with a mean age 62.7 years (31-89) were diagnosed with intraocular metástasis between 1993 and 2014. Both eyes were affected in 4 cases. Location was choroid in 20 cases. The intraocular tumour was the first manifestation of the systemic disease in 13 patients (61.9%). Primary tumour was breast in 47.6% and lung in 23.8%. Diagnosis of the primary tumour was performed by systemic studies, and only 1 patient required intraocular biopsy. Regarding the treatment, the majority of cases were controlled with systemic therapy, with 4 cases requiring additional external beam radiotherapy, and only one enucleation. No clinical differences were found between the cases with known and unknown systemic neoplasia, except in exudative retinal detachment, which was more frequent in the second group. CONCLUSIONS: Although intraocular metastases are the most frequent intraocular tumour, they are not a frequent cause of consultation. In more than half of the cases it is the first presentation of unknown systemic neoplasia as a solitary non-pigmented intraocular mass. Early diagnosis is crucial to establish the appropriate treatment, preserve visual function, and improve the prognosis of the patient
