摘要: Genetic polymorphisms in drug metabolizing enzymes and transporters may affect irinotecan toxicity. Although genetic have been shown to influence the toxicity, data are limited Thai population. Thus, aim of this study was assess allele genotype frequencies relationship between CYP3A4/5, DPYD, UGT1A1, ABCB1, ABCC2 variations irinotecan-induced toxicity colorectal cancer patients. One hundred thirty-two patients were genotyped, effect on assessed 66 who received irinotecan-based chemotherapy. Allele ABCB1 c.1236C > T, c.3435C > T, c.3972C > T, ABCG2 c.421C > A, CYP3A4*1B, CYP3A4*18, CYP3A5*3, DPYD*5, UGT1A1*28, UGT1A1*6 0.67, 0.43, 0.23, 0.27, 0.01, 0.02, 0.64, 0.19, 0.16, 0.09, respectively. DPYD*2A DPYD c.1774C > T variants not detected our The c.3972C > T significantly associated with grade 1–4 neutropenia (P T might be an important predictor for severe neutropenia.
