Real-World Effectiveness of Regorafenib in the Treatment of Patients with Metastatic Colorectal Cancer- A Retrospective, Observational Study
详细描述
To analyze the real-world usage pattern, effectiveness and factors associated with the effectiveness of regorafenib in the treatment of patients with metastatic colorectal cancer (mCRC). This retrospective, observational study included clinicopathological and follow-up data of patients with mCRC who were treated with regorafenib from June 2017 to September 2020. Patients with incomplete data were excluded. Overall survival (OS) stratified by combination therapy with programmed cell death ligand-1 (PD-L1) inhibitors, chemotherapy and regorafenib dose was calculated by Kaplan Meier method and log rank test. R software version 4.0 was used for the analysis.
