TITLE:
摘要: 目的:系统评价骨肉瘤患者亚甲基四氢叶酸还原酶(MTHFR)、还原性叶酸载体1(RFC1)、多药耐药基因1(MDR1)基因多态性对大剂量甲氨蝶呤不良反应的影响,为大剂量甲氨蝶呤临床个体化用药提供循证参考。方法:计算机检索Medline、Embase、clinical trials.gov、中国知网、万方数据和中国生物医学文献数据库,收集MTHFR C677T/A1298C、RFC1 G80A、MDR1 C3435T不同基因多态性与大剂量甲氨蝶呤不良反应相关性的队列研究,对符合纳入标准的临床研究进行资料提取后,采用纽卡斯尔-渥太华量表进行质量评价后,采用Rev Man 5.3、Microsoft Excel 2016对大剂量甲氨蝶呤相关不良反应(血液毒性与骨髓抑制、肝毒性、肾毒性、口腔黏膜炎、消化道毒性、整体不良事件)发生率等结局指标进行Meta分析与描述性分析。结果:共纳入8项队列研究,合计608例患者。报告MTHFR C677T、MTHFR A1298C、RFC1 G80A、MDR1 C3435T多态性相关的结局指标分别有6、5、4、2项。Meta分析与描述性分析结果表明,MTHFR C677T多态性与G3-4肾毒性[TT/CT vs. CC:OR=12.35,95%CI(3.28,46.42),P<0.001]、G3-4口腔黏膜炎[T vs. C:OR=2.04,95%CI(1.06,3.93),P=0.03]、口腔黏膜炎[TT vs. CT/CC:OR=2.27, 95%CI(1.20,4.27),P=0.01]、肾毒性(P<0.05)的发生风险显著相关;MTHFR A1298C多态性与G3-4肝毒性、G3-4肾毒性、G3-4口腔黏膜炎有关,但均无显著相关性(P>0.05);RFC1 G80A多态性与血液毒性、肝毒性、肾毒性、消化道毒性均无显著相关性(P>0.05);MDR1 C3435T多态性与口腔黏膜炎有显著相关性(P<0.05),与血液毒性、肝毒性均无显著相关性(P>0.05)。结论:MTHFR C677T突变可能导致大剂量甲氨蝶呤不良反应发生风险增加,MTHFR A1298C多态性与大剂量甲氨蝶呤不良反应无显著相关性,RFC1 G80A或MDR1 C3435T多态性与大剂量甲氨蝶呤不良反应的研究较少,相关性尚不明确。
ABSTRACT: OBJECTIVE: To systematically evaluate the effects of MTHFR, RFC1 and MDR1 gene polymorphisms on high- dose methotrexate-induced ADR in osteosarcoma patients, and to provide evidence-based reference for individual medication of high-dose of methotrexate. METHODS: Retrieved from Medline, Embase, clinical trials.gov, CNKI, Wanfang database and CBM, cohort studies about the association of MTHFR C677T/A1298C, RFC1 G80A, MDR1 C3435T gene polymorphisms with high-dose methotrexate-induced ADR were collected. After data extraction of clinical studies met inclusion criteria, and quality evaluation with the Newcastle-Ottawa Scale, Meta-analysis and descriptive analysis were performed for outcome indexes as the incidence of high-dose methotrexate-induced ADR (hematotoxicity and myelosuppression, hepatotoxicity, nephrotoxicity, oral mucositis, digestive tract toxicity and overall adverse events) with Rev Man 5.3 and Microsoft Excel 2016 software. RESULTS: Totally 8 cohort studies involving 608 patients were included; 6, 5, 4 and 2 studies reported outcome indexes related to MTHFR C677T/A1298C, RFC1 G80A and MDR1 C3435T gene polymorphisms respectively. Meta-analysis and descriptive analysis showed that MTHFR C677T gene polymorphism was significantly associated with the risk of G3-4 renal toxicity [TT/CT vs. CC: OR=12.35, 95%CI=(3.28,46.42), P<0.001], G3-4 oral mucositis [T vs. C: OR=2.04, 95%CI=(1.06,3.93), P=0.03], oral mucositis [(TT vs. CT/CC: OR=2.27, 95%CI=(1.20,4.27), P=0.01] and renal toxicity (P<0.05); MTHFR A1298C gene polymorphism was associated with G3-4 hepatotoxicity, G3-4 nephrotoxicity and G3-4 oral mucositis, without statistical significance (P>0.05). There was no significant correlation between RFC1 G80A polymorphism and hemotoxicity, hepatotoxicity, nephrotoxicity and digestive tract toxicity (P>0.05). MDR1 C3435T polymorphism was significantly correlated with oral mucositis (P<0.05), but not with hematotoxicity and hepatotoxicity (P>0.05). CONCLUSIONS: MTHFR C677T mutation can increase the risk of high-dose methotrexate-induced ADR. There is no significant association between MTHFR A1298C polymorphism and high-dose methotrexate-induced ADR. There are few studies on RFC1 G80A or MDR1 C3435T polymorphism and high-dose methotrexate-induced ADR, and their association is unclear.
