A liver-targeted breast cancer procedure drew new data at ESMO
Delcath Systems announced new data from a retrospective analysis on percutaneous hepatic perfusion with melphalan (M-PHP) using the CHEMOSAT Hepatic Delivery System for liver-dominant metastatic breast cancer. The data, presented at the ESMO Breast Cancer Congress 2026, showed hepatic partial response in 60% of evaluable patients and highlighted safety considerations like blood transfusions and transient bone marrow suppression. This real-world evidence supports further evaluation of HEPZATO KIT and CHEMOSAT in this heavily pretreated patient population.
