Aim: We examined the utility of the rs924607 TT genotype of the centrosomal protein 72 (CEP72) as a potential biomarker for predilection toward vincristine-induced peripheral neuropathy in children treated for acute lymphoblastic leukemia.
Materials & methods: We conducted a random-effects meta-analysis of data from four studies comprising 817 patients. We tested for an association using a recessive model where a one-sided p-value < 0.05 was considered statistically significant.
Results & conclusion: We were unable to confirm the association between the rs924607 TT genotype and neurotoxicity (odds ratio: 1.99; p = 0.16; 95% CI: 0.76-5.25) in our global meta-analysis. Analysis of the continuation phase (following induction) studies showed significantly higher odds for neuropathy in CEP72 rs924607 TT homozygotes (odds ratio: 2.28; p = 0.02; 95% CI: 1.16-6.87).
