A randomized trial evaluating the association between related gene polymorphism and nausea and vomiting induced by cisplatin multi-day chemotherapy

Abstract

Purpose We aim to investigate the correlation between gene polymorphisms and cisplatin chemotherapy-induced nausea and vomiting (CINV), which was prevented by olanzapine or aprepitant triple antiemetic regimen. Methods Before chemotherapy, the blood samples of 89 malignant tumor patients who received multi-day chemotherapy with cisplatin were collected for sequencing and typing. As there were duplicate patients enrolled in different chemotherapy cycles, there were a total of 190 cases. The patients were divided into two groups randomly, who received the triple antiemetic regimen of olanzapine or aprepitant combined with 5-HT3RA and dexamethasone. The main evaluation indicators were the total protection (TP) rate in the acute phase (0–24 h), the delayed phase (25–120 h) and the overall phase (0-120 h). Results Univariate analysis was performed on genetic loci that reached H-W balance with TP. In the olanzapine group, increased TP in the acute phase was associated with HTR3A rs1176719 non-GG (P < 0.05) genotype etc. Increased TP in the delayed phase was associated with HTR3A rs1176719 non-GG (P < 0.05) genotype etc. In the aprepitant group, increased TP in the acute phase was associated with the MTHFR rs1801131 TT (P < 0.05) genotype etc. Increased TP in the delayed phase was associated with HTR3A rs1062613 CC (P < 0.05) genetype ect. Multivariate Logistic regression analysis showed that HTR3B rs7943062GG (P < 0.05) genotype etc. were correlated with increased TP in the delayed phase. MTHFR rs1801131TT genotype was associated with increased TP in the acute phase (P < 0.05) and delayed phase (P < 0.05). Conclusion This study found that gene polymorphisms, including HTR3B (rs1062613, rs1176719, rs2276303), HTR3B (rs45460698, rs7943062), HTR3C (rs6766410), ERCC1 (rs3212986), ERCC4 (rs744154) and MTHFR(rs1801131), may be independent prognostic factors for CINV.

A prospective randomized controlled clinical trial investigating the efficacy of low-dose olanzapine in preventing nausea and vomiting associated with oxaliplatin-based and irinotecan-based chemotherapy

“…However, it is important to acknowledge the limitations of this study, including the relatively small sample size and the omission of potential risk factors for analysis, such as smoking history, history of motion sickness, and vomiting during pregnancy. Notably, emerging studies indicate potential associations between genetic polymorphisms and chemotherapy-induced nausea and vomiting (Jin et al 2023 ), implying that individual risk factors could influence the efficacy of CINV prevention. The absence of significant differences in CR rates observed in this study might be influenced by these individual risk factors.…”
