Abstract:
Objective:To explore the efficacy and safety of B-Raf proto-oncogene, serine/threonine kinase (BRAF) inhibitor and epidermal growth factor receptor (EGFR) inhibitor combined with immune checkpoint inhibitor in microsatellite stable (MSS) BRAF V600E metastatic colorectal cancer (mCRC) patients.Methods:The data and outcomes of mCRC patients with MSS BRAF V600E who received BRAF inhibitor, EGFR inhibitor combined with immune checkpoint inhibitor in Tianjin Medical University Cancer Hospital from May 2022 to April 2024 were retrospectively collected.Results:A total of 12 mCRC patients were included in this study, the objective response rate was 50.0%, the disease control rate was 66.7%, and the median disease control time of patients who achieved objective response was 8.0 months. The median progression-free survival was 6.8 months and the median overall survival was 8.4 months. Overall adverse reactions were controllable, the most common treatment-related adverse events were fatigue (8 cases), fever (5 cases), and rash (4 cases). There were no grade 4 adverse event, serious adverse event, and treatment-related death.Conclusion:BRAF inhibitor and EGFR inhibitor combined with immune checkpoint inhibitor show good efficacy and controllable safety in BRAF V600E mCRC patients.
