Real-World Effectiveness of Regorafenib in the Treatment of Patients With Metastatic Colorectal Cancer-A Retrospective Study

Real-World Effectiveness of Regorafenib in the Treatment of Patients with Metastatic Colorectal Cancer- A Retrospective, Observational Study

Study Overview

• Status: Recruiting
• Conditions: Metastatic Colorectal Cancer
• Intervention / Treatment: Other: nonintervention

Detailed Description

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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
The difference in overall survival between the two groups calculated by Kaplan-Meier	Survival differences between the monotherapy and combination groups	2021.7-2022.12
The difference of OS in patients receiving different doses of regorafenib	In the real world, regorafenib was used in different dosages: 40mg,80mg,120mg,160mg,respectively. The difference in overall survival time of patients with different dosage was compared.	2021.11-2022.12
Regorafenib in combination with other drugs	In the real world, regorafenib was used in combination with chemotherapy, immunotherapy or other drugs, and the frequency of occurrence of different conditions was analyzed.	2021.7-2022.10

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Survival differences among the patients with different clinical phenotypes and genotypes	To compare the survival of patients with mCRC by gender, age, tumor site and other genotypes	2021.7-2022.10
