Clinical Trial Summary

This study is a retrospective study to compare the efficacy and safety between trifluridine/tipiracil (TAS-102) plus bevacizumab (BEV) with TAS-102 monotherapy in refractory metastatic colorectal cancer (mCRC) from November 2020 to October 2022 at the Hunan Cancer Hospital.

Description:

Our retrospective analysis was conducted to explore the efficacy and safety of patients treated with at least 1 cycle of TAS-102 with or without BEV in patients suffering refractory mCRC from November 2020 to October 2022 at the Hunan Cancer Hospital. Data from the electronic medical records were the sources. In TAS-102 monotherapy group, TAS-102 35 mg/m²orally twice a day on days 1-5 and 8-12, every 28 days were given to patients, while on days 1 and 15, every 28 days, patients received bevacizumab (5 mg /kg, intravenously) in TAS-102 plus BEV group. The median OS (mOS) was the primary end point.while mPFS, the ORR, the disease control rate(DCR) and the incidence of treatment-related adverse events (TRAEs) were the secondary end points.
