Background
Trifluridine/tipiracil plus VEGF inhibition with ramucirumab (RAM) for advanced gastric cancer (AGC) demonstrated clinical activity with an acceptable toxicity profile in previous phase II trial. However, little is known about its efficacy and safety in clinical practice in comparison with trifluridine/tipiracil monotherapy.
Methods
We retrospectively investigated efficacy and safety of trifluridine/tipiracil plus RAM and trifluridine/tipiracil monotherapy as third or later line treatment for AGC patients.
Results
Forty-one patients receiving trifluridine/tipiracil plus RAM and 60 patients receiving trifluridine/tipiracil monotherapy were analyzed. The objective response rate (ORR) and the disease control rate (DCR) were 13.5% and 64.9% in the trifluridine/tipiracil plus RAM group, and 3.8% and 42.3% in the trifluridine/tipiracil monotherapy group, respectively (ORR; P = 0.122, DCR; P = 0.052). The median progression-free survival (PFS) and the median overall survival (OS) were 3.0 months and 7.2 months in the trifluridine/tipiracil plus RAM group, and 1.8 months and 3.8 months in the trifluridine/tipiracil monotherapy group, respectively (HR for PFS = 0.66; P = 0.059, HR for OS = 0.50; P = 0.007). Multivariate analysis showed significantly longer PFS (HR = 0.52; P = 0.011) and OS (HR = 0.51; P = 0.031) in the trifluridine/tipiracil plus RAM group compared to the trifluridine/tipiracil monotherapy group. No unexpected adverse events were observed in both groups.
Conclusions
Trifluridine/tipiracil plus RAM might show favorable anti-tumor activity with an acceptable toxicity profile in comparison with trifluridine/tipiracil monotherapy, suggesting one treatment option for AGC patients in salvage line. The combination needs further evaluation in ongoing randomized trials.
