    Abstract:
    OBJECTIVE: To study the effects of single-nucleotide polymorphisms of the OPRM1 and ABCB1 genes on the analgesic effect and consumption of sufentanil after thoracoscopic-assisted radical resection of lung cancer. METHODS: A total of 225 Chinese Han nationality patients undergoing thoracoscopic-assisted radical resection of lung cancer were enrolled in the present study. Among them, 132 were males (58.67%) and 93 (41.33%) were females having American Society of Anesthesiologists statuses classified as grades I or II. The rs1799971, rs563649 and rs1323040 genotypes of the OPRM1 gene and rs2032582, rs1045642 and rs1128503 genotypes of the ABCB1 gene were detected by Sanger sequencing. The state anxiety index and pressure pain threshold were assessed preoperatively. Sufentanil was administered intravenously to maintain anesthesia. The doses and side effects of sufentanil consumed 6 h (T1), 24 h (T2) and 48 h (T3) after surgery were recorded. RESULTS: The sufentanil doses at T1, T2 and T3 were significantly higher in radical-operation lung cancer patients with mutant homozygous rs1799971 and rs1323040 loci in the OPRM1 gene and rs2032582 and rs1128503 loci in the ABCB1 gene. The doses of sufentanil consumed by mutant heterozygous lung cancer patients at T1, T2 and T3 were significantly higher than those consumed by patients without mutations, and the differences were statistically significant (P<0.05). There was no significant difference in sufentanil doses consumed by lung cancer patients with mutant homozygous, mutant heterozygous and wild-type rs563649 locus of the OPRM1 gene and rs1045642 locus of the ABCB1 gene at T1, T2 and T3 (P>0.05). There was no significant difference in the visual analog scale scores at T1, T2 and T3 for different genotypes of OPRM1 and ABCB1 genes in lung cancer patients (P>0.05). No significant difference was found between the adverse reactions of OPRM1 and ABCB1 genotypes in patients undergoing radical resection of lung cancer (P>0.05). CONCLUSION: The rs1799971 and rs1323040 polymorphisms of the OPRM1 gene and rs2032582 and rs1128503 polymorphisms of the ABCB1 gene are related to the analgesic effect and consumed dose of sufentanil in Chinese Han patients undergoing radical operation of lung cancer.
