Cost-effectiveness analysis of pembrolizumab versus chemotherapy as first-line treatment for mismatch-repair-deficient (dMMR) or microsatellite-instability-high (MSI-H) advanced or metastatic colorectal cancer from the perspective of the Chinese health-care system.

ABSTRACT:

Background

Pembrolizumab is superior to chemotherapy as a first-line treatment for patients with mismatch-repair-deficient (dMMR) or microsatellite-instability-high (MSI-H) advanced or metastatic colorectal cancer (CRC), with a significant long-term survival benefit according to the KEYNOTE-177 trial. The current study aimed to determine whether pembrolizumab is a cost-effective treatment for patients with dMMR/MSI-H advanced or metastatic CRC in China.

Methods

A partitioned survival model (PSM) was developed to simulate patients with dMMR/MSI-H advanced or metastatic CRC based on progression-free survival (PFS), progressive disease (PD) and death. The model was designed using a lifetime horizon, a 6-week cycle, and a 5% discount rate. The patients in the model had metastati
