摘要
背景：酶编码基因中的单核苷酸多态性（SNPs）在抗癌治疗的易感性中发挥作用：对51名接受氟嘧啶类化疗的结直肠癌患者的酶活性与治疗反应、药物毒性和超敏反应之间的关系进行了前瞻性研究。研究对 22 个酶编码基因中的 SNP 进行了分析，这些基因以前曾被描述过在疗效中的作用：结果：SLC6和MTHR酶活性与疾病进展率有关，GSTP1活性与抗EGFR抗体相关的皮肤毒性有关，CYP3A5和MTHR与化疗剂量减少有关，CYP2B6、IL10、MTHR和TYMS活性与药物超敏反应风险有关：药物遗传学是肿瘤学中与化疗反应、毒性和超敏反应相关的重要预测指标。
Single nucleotide polymorphisms: impact on susceptibility to chemotherapy in patients with colorectal cancer.
Background: Single-nucleotide polymorphisms (SNPs) in enzyme-coding genes play a role in susceptibility to anti-cancer therapy.
Materials & methods: A prospective study was performed of the relationship between enzyme activity and treatment response, drug toxicity and hypersensitivity reactions in 51 patients with colorectal cancer treated with fluoropyrimidine-based chemotherapy. SNP analysis was performed in 22 enzyme-coding genes with a previously described role in treatment efficacy.
Results: SLC6 and MTHR enzyme activity was related with rates of progressive disease, GSTP1 activity with anti-EGFR antibodies-related skin toxicity, CYP3A5 and MTHR with chemotherapy dose reduction, CYP2B6, IL10, MTHR and TYMS activity with the risk of drug hypersensitivity reactions.
Conclusion: Pharmacogenetics is a valuable predictive marker in oncology, related to chemotherapy treatment response, toxicity and hypersensitivity.
