Abstract:

Objective To assess the effect of CYP3A4 *1G polymorphism on the dose of fentanyl in patients undergoing laparoscopic radical resection of colorectal cancer. Methods Totally,101 patients receiving fentanyl anesthesia laparoscopic radical resection of colon tumors at Zhongshan Hospital of Fudan University between July 2018 and April 2020 were enrolled. CYP3A4 *1G genotype was determined,and the relation between CYP3A4 *1G polymorphism and the dose of fentanyl was evaluated by multiple linear regression analysis. Results The results of multiple linear regression analysis showed that age,intraoperative fentanyl dose and the polymorphisms of CYP3A4 *1G,CYP3A5 *3 and OPRM1 A118G were risk factors for the dose of fentanyl in post-anesthesia care unit (PACU)(P<0.05). After adjusting for age,sex,weight,height,intraoperative fentanyl dose,operation time and the polymorphisms of OPRM1 A118G,CYP3A5 *3 and COMT V158M,CYP3A4*1G wild type(*1*1) was found to be a risk factor for increased fentanyl dose in PACU [β=-13.99,95% confidence interval(CI) -26.78--1.20,P=0.035]. Compared to fentanyl dose in patients with CYP3A4 *1G mutant genotypes [*1*1G(heterozygous) and *1G*1G(homozygous)],the wild type ones were 13.99 μg higher. There was no correlation between CYP3A4 *1G polymorphism and fentanyl dose in 24 h patient-controlled intravenous analgesia (PCIA) after operation(β=-7.79,95% CI -33.70--18.11,P=0.557),as well as that in 48 h PCIA after operation(β=-10.28,95% CI -22.70-2.15,P=0.108). Compared with CYP3A4*1G wild type (*1*1) patients,the PACU and fentanyl dose in 24 h PCIA after operation of patients with CYP3A4*1G mutant genotypes [*1*1G (heterozygous) and *1G*1G (homozygous)] were decreased (P<0.05). Conclusions CYP3A4 *1G polymorphism is an independent factor for fentanyl dose. Compared with mutated type,the anesthetic effect may be similar to wild type subjects by consuming less fentanyl.
