Abstract:

Objective This study aims to investigate the correlations between SCN10A, glutathione S‑transferase P‑1 (GSTP1), and methylenetetrahydrofolate reductase (MTHFR) gene polymorphisms and oxaliplatin‑induced peripheral neurotoxicity (OIPN) among colorectal cancer patients treated with oxaliplatin‑based chemotherapy. Methods The clinical data of 160 patients with colorectal cancer who received oxaliplatin-based chemotherapy at Wuhan No.1 Hospital between January 2023 and January 2025 were retrospectively analyzed. Genotypes of the SCN10A (rs12632942), GSTP1 rs1695 (Ile105Val), and MTHFR rs1801133 (C677T) loci were detected via polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Associations between the genotypes of these loci, patients' clinicopathological characteristics, OIPN grading, and OIPN risk were further investigated. Results Among the 160 enrolled patients, the overall incidence of OIPN was 77.5% (124/160), and the incidence of severe neurotoxicity (grade ≥ 3) was 23.1% (37/160). Comparisons of pathophysiological characteristics across different genotype groups at the SCN10A rs12632942, GSTP1 rs1695, and MTHFR rs1801133 loci revealed no statistically significant between-group differences (all P > 0.05). At the SCN10A rs12632942 locus, patients with the CT or TT genotype had a significantly higher incidence of chronic OIPN than patients with the CC genotype (P < 0.05), and the CT or TT genotype was identified as an independent risk factor for chronic OIPN (P < 0.05). At the GSTP1 rs1695 locus, patients with the AG or GG genotype had a significantly higher incidence of acute OIPN than patients with the AA genotype (P < 0.05). Multivariate regression analysis confirmed that the AG or GG genotype is an independent risk factor for acute OIPN (P < 0.05). No statistically significant differences in the incidence of either acute or chronic OIPN were observed across different genotype groups at the MTHFR rs1801133 locus (all P > 0.05). Conclusions SCN10A rs12632942 and GSTP1 rs1695 polymorphisms are potential genetic risk factors for chronic and acute OIPN in patients with colorectal cancer, respectively. No significant correlation was observed between MTHFR rs1801133 and the occurrence of OIPN.
