ABSTRACT
BACKGROUND:
Trifluridine/tipiracil (TAS-102) has achieved modest efficacy in the late-line treatment of metastatic colorectal cancer. The present study aimed to explore the clinical efficacy and drug toxicities of TAS-102 for patients with metastatic colorectal cancer in real-world clinical setting.METHODS:
From October 2020 to February 2022, patients with metastatic colorectal cancer who failed from 2 or more lines of prior therapy and treated with TAS-102 monotherapy, in combination with bevacizumab or immune checkpoint inhibitors (ICIs) were analyzed. The evaluation indicators were progression free survival (PFS), objective response rate , disease control rate (DCR), overall survival (OS) and drug toxicities.RESULTS:
A total of 70 patients were enrolled. The objective response rate and DCR were 1.4% and 68.6%. The median PFS and OS were 6.0 (95% CI 4.1-7.9) and 10.0 (95% CI 8.3-11.7) months. Compared with TAS-102 monotherapy and TAS-102 plus ICIs, TAS-102 plus bevacizumab obtained superior DCR (75.9% vs. 50% vs. 40%, P = .047), PFS (6.3m vs. 3.0 m vs. 3.0 m, P = .041) and OS (12.0 m vs. 6.5 m vs. 6.0m, P = .013). Patients without prior regorafenib or fruquintinib therapy obtained better median PFS (6.3 vs. 4.3 m, P = .031) and OS (NR vs. 9.0 m, P = .036). Other indicators, including age, tumor site, KRAS status and use of fluoropyrimidine as last regimen before TAS-102, did not affect the clinical efficacy of TAS-102. The most frequent adverse events were leukopenia, neutropenia, anemia, fatigue, nausea, and vomiting.CONCLUSION:
In real-world clinical setting, TAS-102 showed consistent clinical efficacy and manageable safety with previous prospective clinical studies. Compared with monotherapy and TAS-102 plus ICIs, TAS-102 plus bevacizumab demonstrated better clinical efficacy for metastatic colorectal cancer.Palavras-chave
