Abstract

Objective Trifluridine/tipiracil (FTD/TPI) is one of the options for late-line treatment of colorectal cancer (CRC). However, the specific patient populations that would particularly benefit from it remain unclear. This study attempted to identify predictive markers of chemotherapy efficacy with trifluridine/tipiracil (FTD/TPI), focusing on the RNA-editing enzyme adenosine deaminase acting on RNA 1 (ADAR1) expression and neutrophil–lymphocyte ratio (NLR).
