OBJECTIVE: Oxaliplatin-induced neuropathy is a significant complication of cancer therapy. We aimed at investigating the risk factors of oxaliplatin-induced neuropathy (OIPN) and providing evidence to enhance its prevention.

MATERIALS AND METHODS: PubMed, Medline, Web of Science, Embase, China Knowledge Resource Integrated Database, and the Wanfang Database were searched comprehensively for observational studies investigating the prevalence and risk factors of OIPN from inception to November 30, 2021. The Newcastle-Ottawa Scale was used by two independent reviewers to assess methodological quality. When applicable, we used meta-analysis to determine mean differences and odds ratios for continuous and nominal scaled data.

RESULTS: We included 20 studies involving 10,900 participants for analysis. Factors associated with OIPN risk identified by meta-analysis were age, gender, diabetes, anemia, hypomagnesaemia, alcohol consumption, body mass index, body surface area, cumulative oxaliplatin dose and the number of chemotherapy cycles. Factors not associated with OIPN risk included smoking history and chemotherapy regimen.

CONCLUSIONS: This meta-analysis identified multiple variables associated with OIPN. The recognition of modifiable risk factors is an urgent priority to improve prevention and treatment outcomes.
