About this study
Official title: 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
Read the 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 participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
noninterventionOther
| Study group | Role | What they receive |
|---|---|---|
| Regorafenib group | Patients were given only regorafenib orally Receives: Other: nonintervention | |
| Joint group | The patient was treated with regorafenib orally and in combination with other medications Receives: Other: nonintervention |
What is being measured
The primary outcome is the main question the study is designed to answer.
The difference in overall survival between the two groups calculated by Kaplan-Meier
Survival differences between the monotherapy and combination groups
Measured: 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.
Measured: 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.
Measured: 2021.7-2022.10
Secondary outcomes (1)
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
Measured: 2021.7-2022.10
