Ocular Sebaceous Carcinoma

The study involves enrollment of patients with sebaceous carcinoma, Merkel's carcinoma, Porocarcinoma, Melanoma, and squamous cell Ca of the ocular surface and adnexa both primary and relapsed after surgical and/or radiation-chemotherapy treatment at the Fondazione Policlinico Universitario A. Gemelli, IRCCS. The study will last 9 years: 1 year will be devoted to the first phase of the study. Patient enrollment will continue for an additional 3 years, and 5 years will be devoted overall to patient follow-up so that survival outcomes at 1-3 and 5 years can be assessed in a congruent number of patients. A preliminary analysis of the data at 1 year (pilot phase), an analysis at 4 years to confirm the preliminary study data on a larger sample, and a final analysis to evaluate OS and PFS at the 3 time-points indicated are planned.
