NEW YORK, Feb. 21, 2017 (GLOBE NEWSWIRE) -- Delcath Systems, Inc. (NASDAQ:DCTH), an interventional oncology company focused on the treatment of primary and metastatic liver cancers, announced that a retrospective, multicenter study demonstrated that 45.7 percent of patients with ocular melanoma that metastasized to the liver who underwent percutaneous hepatic perfusion (PHP) using investigational Melphalan/HDS experienced a complete or partial response. The study further showed that among those who responded to treatment, overall survival was projected to be more than three years.

The findings were reported at the Regional Cancer Therapies 12th International Symposium in an oral presentation titled, "Percutaneous Hepatic Perfusion for Unresectable Metastatic Ocular Melanoma to the Liver: A Multi-Institutional Report of Outcomes." The analysis was conducted by teams from Moffitt Cancer Center in Tampa, Fla., and the University Hospital Southampton in the United Kingdom. The presentation was led by Dr. Alexandra Gangi of the Moffitt Cancer Center.

The analysis reviewed outcomes of 49 patients treated between 2008 and 2016 with Melphalan/HDS at either the Moffitt Cancer Center or the University Hospital Southampton. Patients underwent a total of 115 PHP treatments. The median number of treatments per patient was two, with patients receiving one-to-six treatments. PHP is a minimally invasive procedure that isolates the liver from the body
