Abstract
BACKGROUND: Uveal melanoma often metastasizes to the liver, portending a poor prognosis. Melphalan/hepatic delivery system (HDS) via percutaneous hepatic perfusion (PHP) is a minimally invasive means of circulating high-dose chemotherapy through the affected liver. This study evaluated melphalan/HDS use as either first-line or second-line treatment to guide treatment sequencing.
PATIENTS AND METHODS: A retrospective review included patients with hepatic-dominant metastatic uveal melanoma who underwent melphalan/HDS treatment via PHP from 2008 to 2023.
RESULTS: A total of 30 patients were identified; 53.3% female, with a median age of 63.5 years (37-78 years). Median follow-up time was 14.5 months. First-line therapies included melphalan/HDS (n = 17), liver-directed (n = 7), and immunotherapy (n = 6). Second-line therapies included melphalan/HDS (n = 6), immunotherapy (n = 5), and liver-directed (n = 3). Median hepatic progression-free survival (hPFS) for first-line melphalan/HDS, immunotherapy, and liver-directed therapy was 17.6/8.8/9.2 months, respectively (P = 0.002). Median hPFS for second-line melphalan/HDS, immunotherapy, and liver-directed therapy was not reached/14.7/7.5 months, respectively (P < 0.001). Median overall PFS for first-line melphalan/HDS, immunotherapy, and liver-directed therapy was 15.4/8.8/9.2 months, respectively (P = 0.04). Median overall PFS for second-line melphalan/HDS, immunotherapy, and liver-directed therapy was 22.2/14.7/7.5 months, respectively (P = 0.001).
CONCLUSIONS: Melphalan/HDS via PHP for metastatic uveal melanoma to the liver was found to have significantly improved hPFS and overall PFS when used as first-line therapy compared with immunotherapy or liver-directed therapy. PHP continued to demonstrate improved hPFS and PFS when used as second-line therapy compared with second-line immunotherapy or liver-directed therapy.
