摘要
目的:探讨SCN9A基因多态性与肺癌病人疼痛发生之间的相关性,同时分析其与阿片类药物镇痛剂量间的关系。方法:采用聚合酶链反应-限制性片段长度多态性(PCR-RFLP)的方法检测246例肺癌病人和106例对照者的SCN9A-rs6746030位点基因分型。对影响肺癌疼痛发生的混杂因素进行单因素分析及多因素logistic回归分析。采用Mann-Whitney检验比较不同基因型间阿片类药物用量的差异。结果:(1)疼痛组、无痛组和对照组的rs6746030等位基因(G/A)频率分别为0.83/0.17、0.94/0.06和0.95/0.05,无痛组和对照组基因分型无统计学差异;(2)疼痛组与无痛组相比,基因型GA/AA为肺癌疼痛发生的独立危险因素(P <0.001, OR=3.695, 95%CI=1.883-7.253);Ⅲ-Ⅳ期肺癌病人的疼痛发生风险显著增高(P=0.009, OR=2.339, 95%CI=1.235-4.431);(3)中、重度疼痛组病人不同基因型间24 h阿片类药物用量无统计学差异。结论:尚不认为SCN9A-rs6746030多态性影响肺癌疼痛病人阿片类药物的镇痛剂量,但基因型GA/AA可能是影响肺癌病人疼痛发生的独立危险因素之一。
Objective: To investigate the association between SCN9 A gene polymorphism and pain susceptibility in patients with lung cancer, and to analyze the effect of the gene polymorphism on the analgesic dose of opioids. Methods: The genotypes of SCN9A-rs6746030 in 246 lung cancer patients and 106 healthy people were detected by the polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP). The mixed factors of pain susceptibility in patients with lung cancer were analyzed by univariate analysis and logistic regression model. The difference of opioids dosage between different genotypes was compared by the Mann-Whitney test. Results:(1) The frequencies of rs6746030 allele(G/A) in pain group, painless group and control group were 0.83/0.17, 0.94/0.06 and 0.95/0.05 respectively. There was no difference in genotypes between painless group and control group;(2) In the comparison between pain group and painless group, the logistic regression analysis showed that genotype GA/AA was an independent risk factor of pain susceptibility in lung cancer patients(P < 0.001, OR = 3.695, 95%CI = 1.883-7.253). The risk of cancer pain was significantly higher in the stage of Ⅲ-Ⅳ(P = 0.009, OR = 2.339, 95%CI = 1.235-4.431);(3) There was no significant difference in the analgesic dose of opioids in different genotypes among patients with moderate and severe pain. Conclusions: The polymorphism of SCN9A-rs6746030 may not affect the analgesic dose of opioids in patients with lung cancer pain, but the genotype GA/AA may be one of the independent risk factors of pain susceptibility in lung cancer patients.
