Cost-effectiveness analysis of durvalumab combined with tremelimumab versus sorafenib as first-line treatment for unresectable Hepatocellular carcinoma in China: a dual-model approach utilizing partitioned survival and markov models

Background

Hepatocellular carcinoma (HCC) is a major contributor to global cancer-related mortality, with the majority of patients diagnosed at unresectable stages. The STRIDE regimen (tremelimumab plus durvalumab) demonstrated superior survival benefits over sorafenib in the HIMALAYA trial. However, its cost-effectiveness within the Chinese healthcare system remains unverified.
