Treatment Patterns and Survival in Patients with Intermediate, Advanced, or Terminal Stage of Hepatocellular Carcinoma in France over the Period 2015-2017: A Real-Life Study

Abstract

Background. The prognosis of patients with hepatocellular carcinoma (HCC) not eligible to curative treatment is poor. Little information is available on treatment modalities and outcomes of these patients in everyday practice. The aim of this analysis was to describe the characteristics of patients with a newly diagnosed intermediate, advanced, or terminal (IAT) stage of HCC (ICD-10: C220) between 2015 and 2017, either present at diagnosis of HCC or having occurred after disease progression; treatment patterns, HCC aetiologies, and the associated survival were determined using the nationwide claims database. Methods. Patients with HCC were identified using the ICD-10 code C220. IAT stages, defined according to the terminology used in the Barcelona Clinic Liver Cancer classification, were indirectly identified by the presence of at least one of the following treatments: transarterial chemoembolization (TACE), transarterial radioembolization (TARE), HCC systemic therapy, best supportive care (BSC), or an ICD-10 code of metastatic HCC. Treatment patterns were described with an algorithm based on a ranking of palliative treatments identified. Survival was analysed by using Kaplan-Meier curves. Results. 19,649 eligible patients were identified. Their mean age was 70.5 years (SD: 11.0), and 82.5% were males. For 68.8% of patients, the IAT stage was present at HCC diagnosis. On the whole population, 5,114 patients (26.0%) were treated initially with a TACE or TARE, and 4,681 (23.8%) received a targeted systemic therapy at any moment during follow-up with sorafenib in 99.5% of cases. About 7,628 patients (45.6%) received only BSC. Survival since the diagnosis of the AIT stage of HCC differed according to the type of the first received palliative treatment. Median overall survival was 23.8, 9.6, 7.4, and 1.0 months in patients initially receiving TACE, TARE, systemic therapy, and BSC only, respectively. Conclusion. Over the period 2015-2017, hepatocellular carcinoma was still often diagnosed in France at late-stage disease with a very poor prognosis.
