Independent Analysis of CHEMOSAT PHP in Liver-Dominant Metastatic Uveal Melanoma
Independent investigators from St Vincent's University Hospital in Dublin, Ireland published a retrospective analysis of patients with liver-dominant mUM who were referred to University Hospital Southampton for chemosaturation with percutaneous hepatic perfusion (CS-PHP) between 2019 and 2026. The abstract, "Outcomes and safety of chemosaturation with percutaneous hepatic perfusion (CS-PHP) in liver-dominant metastatic uveal melanoma: Impact of molecular profiling on survival" (Abstract 119P), appears in ESMO Open, Volume 11, Supplement 7 (September 2026), and is available here.
