OBJECTIVE: The aim of this study was to evaluate the relationship between single nucleotide polymorphism (SNP) (-135 T>C) of TNFRSF1 A and the frequency of occurrence and severity of oral mucositis (OM) in patients with head and neck cancer (HNC) treated with radiotherapy (RT). STUDY DESIGN: This retrospective, cohort study included 60 patients with HNC treated with intensity-modulated radiation therapy (IMRT). TNFRSF1 A SNP analysis (-135 T>C) was performed by using molecular probes (TaqMan, ThermoFisher Scientific, Waltham, MA) in DNA isolated from peripheral blood (QIAamp DNA MiniKit; Qiagen, Germantown, MD). RESULTS: CC genotype was related to 4.5-fold higher risk of grade 2 OM after the second week of RT. Similarly, CC carriers had a significantly higher risk of severe (grade 3) OM after the fourth (6-fold) and fifth (7.5-fold) weeks of RT. The CC genotype of the TNFRSF1 A gene was significantly correlated with a higher risk of shorter overall survival (OS) (> 37 months follow-up period; hazard ratio [HR] = 2.78). CONCLUSIONS: SNP (-135 T>C) of the TNFRSF1 A gene may act as a predictor of OM occurrence in patients with HNC treated with IMRT. The studied SNP may also serve as a prognostic factor in such cases.
目的:本研究旨在评估肿瘤坏死因子受体超家族成员 1A(TNFRSF1A)单核苷酸多态性(SNP)(-135 T>C)与接受放射治疗(RT)的头颈部癌症(HNC)患者口腔黏膜炎(OM)的发生频率和严重程度之间的关系。
研究设计:这是一项回顾性队列研究,纳入了 60 例接受调强放疗(IMRT)的 HNC 患者。通过使用来自外周血的 DNA (QIAamp DNA MiniKit;Qiagen,Germantown,MD)中的分子探针(TaqMan,ThermoFisher Scientific,Waltham,MA)对 TNFRSF1A SNP 分析(-135 T>C)。
结果:CC 基因型与 RT 后第二周 2 级 OM 的风险增加 4.5 倍相关。同样,CC 携带者在 RT 后第四(6 倍)和第五(7.5 倍)周发生严重(3 级)OM 的风险显著更高。TNFRSF1A 基因的 CC 基因型与较短的总生存(OS)风险增加显著相关(>37 个月随访期;风险比[HR] = 2.78)。
结论:TNFRSF1A 基因的 SNP(-135 T>C)可能是接受 IMRT 的 HNC 患者 OM 发生的预测因子。在这种情况下,研究中的 SNP 也可能作为预后因素。
