Systemic treatments with tyrosine kinase inhibitor and platinum-based chemotherapy in patients with unresectable or metastatic hepatocholangiocarcinoma

Backgrounds and aims: Even if no systemic treatment is currently validated for unresectable hepato-cholangiocarcinoma (cHCC-CCA), tyrosine kinase inhibitors (TKI), and platinum-based chemotherapy are frequently used in clinical practice. Our study aims to describe the effectiveness of first-line systemic treatments in patients with cHCC-CCA. Patients and Methods: Patients with histological diagnosis of unresectable or metastatic cHCC-CCA confirmed by a centralized review (WHO classification 2019) and who received systemic treatment from 2009 to 2020 were included retrospectively in 11 centers. The outcomes of patients with cHCC-CCA were compared with patients with hepatocellular carcinoma (HCC) treated by sorafenib (n=117) and with intrahepatic cholangiocarcinoma (iCCA, n=94) treated mainly by platinum-based chemotherapy using a frailty Cox model. The efficacy of tyrosine kinase inhibitors and platinum-based chemotherapies in patients with cHCC-CCA was assessed using a doubly robust estimator. Results: A total of 83 patients with cHCC-CCA were included and were predominantly male (72%) with underlying cirrhosis (55%). 67% of patients had extrahepatic metastases and 31% macrovascular tumor invasion. cHCC-CCAs were more often developed on cirrhosis (55.4%) than iCCA (26.6%) but less frequently than HCC (80.2%)(p
