摘要: Purpose To identify genetic markers in the pharmacokinetic and pharmacodynamic pathways of sunitinib that predispose for development toxicities: thrombocytopenia, leukopenia, mucosal inflammation, hand-foot syndrome, any toxicity according to National Cancer Institute Common Toxicity Criteria higher than grade 2. Patients Methods A multicenter pharmacogenetic association study was performed 219 patients treated with single-agent sunitinib. total 31 single nucleotide polymorphisms 12 candidate genes, together several nongenetic variants, were analyzed a possible toxicity. In addition, haplotypes developed related Results The risk leukopenia increased when G allele CYP1A1 2455A/G (odds ratio [OR], 6.24; P = .029) or T FLT3 738T/C (OR, 2.8; .008) present CAG NR1I3 (5719C/T, 7738A/C, 7837T/G) haplotype 1.74; .041) absent. Any 2 prevalence inc...
