Uveal melanoma metastatic at initial diagnosis: a case series

xlomafota13 shared this article with you from Inoreader Uveal melanoma metastatic at initial diagnosis: a case series Via Melanoma Research - Current Issue Detectable metastasis at the time of initial diagnosis of uveal melanoma (UM) is rare. The purpose of this investigation was to evaluate the characteristics and outcomes in patients with metastatic UM (MUM) at initial diagnosis. An institutional review board-approved retrospective case series analysis was performed in 21 patients that presented for management of MUM at initial diagnosis. Patient, tumor and treatment parameters were recorded, and ophthalmic symptoms, metastasis response and overall survival were assessed. Among 21 patients, median tumor diameter was 18 mm (range, 9.1–35 mm), with 76% classified as a Collaborative Ocular Melanoma Study (COMS) large size. Sites of metastasis included liver (95%), bone (29%) and lung (29%), among others, and were confirmed by biopsy in 95% of patients studied. Symptomatic primary tumors were present in 81%, causing pain (24%) or vision loss (57%). Primary tumor therapy (PTT) was provided upfront for 52% of patients with enucleation (24%) and brachytherapy (29%). Eye pain developed 3–6 months after diagnosis in four of 10 patients who did not receive upfront PTT, whereas it did not occur in any of the 11 patients who received upfront PTT (P = 0.04). PTT palliated pain in all cases. The median overall survival was 11.9 months (range, 2.5–21.1 months). Patients presenting with MUM at initial diagnosis have high-risk tumors and experience survival like patients who develop metastases metachronously. PTT is not associated with survival but may mitigate ophthalmic symptoms, especially in patients with large tumors at risk for causing symptoms. View on the web Inoreader.
