Feasibility and safety of nivolumab in advanced hepatocellular carcinoma: real-life experience from three German centers

IntroductionNivolumab is the first checkpoint-inhibitor approved for the treatment of advanced HCC patients. Real-life experience data of nivolumab treatment in HCC patients, especially those with advanced liver disease, is scarce.Materials and methodsAll patients with confirmed advanced HCC and nivolumab treatment from three large German centers were retrospectively analyzed. Clinical parameters and outcome were assessed.ResultsA total of 34 patients were included. At the time of treatment initiation 5 patients (14.7%) were classified as stage BCLC B and 29 (85.3%) BCLC C, respectively. 25 (73.5) patients had received prior sorafenib treatment. All patients presented with cirrhosis, namely Child-Pugh stages A (56%) or B (41%), respectively. At time of patient's assessment, 20 out of 34 (58.8%) patients had died. Grade 3 toxicities occurred in two patients (5.9%). Best overall responses were partial response in four patients (11.8%) and stable disease in eight patients (23.5%). The median overall survival of the whole cohort was 7.5 weeks (range 0-46). Child-Pugh B stage disease at treatment start was significantly associated with poor outcome.DiscussionNivolumab treatment seems safe and clinical efficacious. Patients with advanced liver disease require further prospective evaluation due to probable limited efficacy of nivolumab.
