Abstract
- Background/aim: Although peripheral neuropathy (PN) is a common adverse event in patients treated with oxaliplatin as first-line chemotherapy (1st-OX) for advanced gastric cancer, the effect of PN on the efficacy of paclitaxel at second-line chemotherapy (2nd-PTX) remains unclear. We investigated the association between PN induced by 1st-OX and efficacy of 2nd-PTX in patients with advanced gastric cancer (AGC).<br />Patients and Methods: The study subjects were patients with AGC who received 1st-OX followed by 2nd-PTX at Gifu University Hospital between January 2015 and December 2019. Primary outcome was time to treatment failure (TTF) of 2nd-PTX. Secondary outcomes included overall survival (OS), response rate and adverse events during the period of 2nd-PTX. The association between incidence of grade ≥2 peripheral neuropathy (G2PN) and TTF or OS was also evaluated using Cox proportional hazards analysis.<br />Results: A total of 54 patients with AGC who received 1st-OX followed by 2nd-PTX were eligible. Incidence rates of G2PN at the start of 2nd-PTX was 20.3% (11/54). Median duration of TTF and OS were not significantly longer in patients with G2PN than in those without it (TTF: 4.7 months vs. 3.7 months, p=0.264, OS: 10.6 months vs. 8.5 months, p=0.706). Cox proportional hazards analysis indicated that there was no significant relationship between the incidence of G2PN and TTF, or between the incidence of G2PN and OS. However, development of grade ≥3 PN was significantly higher in patients with G2PN than in those without it (45.5% vs. 2.3%, p<0.001).<br />Conclusion: G2PN induced by 1st-OX may not affect efficacy of 2nd-PTX in patients with AGC but could be a risk for grade ≥3 PN of 2nd-PTX.<br /> (Copyright © 2022 International Institute of Anticancer Research (Dr. George J.
