Of 35 patients with metastatic ocular melanoma, 71.4% manifested liver involvement either initially (45.7%) or later in the course of the disease (25.7%). With liver involvement, the median survival was 2.2 months, whereas with pulmonary involvement it was 19.2 months after the first evidence of metastatic disease (P less than 0.01). Survival after recurrence varied also with age, those younger than 50 years having median survival of 14 months, with those 50 years or older having median survival 3.5 months (P less than 0.01). It also varied with the patient's sex, males having median survival 3 months after recurrence, and females 10.4 months (P less than 0.05). Younger patients and females had also longer disease-free intervals prior to recurrence. Surgical removal of metastases, when feasible, in combination with chemotherapy, seems to offer improved palliation, since a subsequent median survival thus of 18.4 months was observed with 3/15 patients alive disease-free 1 to 3 years later, while the median survival of 20 patients not treated with surgery was 2.5 months. Most of this difference in survival, however, is due to a difference in tumor load between the two groups, with patients subjected to surgery having lesser amounts of tumor and/or more favorable sites.
