| 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). Methods To assess the effectiveness of FTD/TPI in CRC patients, we retrospectively analyzed 72 CRC patients at Okayama University Hospital from 2014 to 2022. Results Adding bevacizumab to FTD/TPI resulted in a more prolonged progression-free survival (PFS), consistent with the SUNLIGHT study findings (p = 0.0028). Among the participants, those with a high NLR had a shorter PFS (p = 0.0395). Moreover, high ADAR1 expression was associated with longer PFS (p = 0.0151). In multivariate analysis, low ADAR1 (HR = 3.43, p = 0.01) and absence of bevacizumab (HR = 4.25, p = 0.01) were identified as factors shortening PFS. The high ADAR1 group demonstrated fewer cases of progressive disease and a higher proportion of stable disease than the low ADAR1 group (p = 0.0288). Low NLR and high ADAR1 were predictive markers of prolonged PFS in the bevacizumab-treated group (p = 0.0036). Conclusion Low NLR and high ADAR1 were predictive markers for a positive response to the FTD/TPI plus bevacizumab regimen associated with prolonged PFS. The FTD/TPI plus bevacizumab regimen should be proactively implemented in the low NLR and high ADAR1 subgroups. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
