Abstract:鼻咽癌(NPC)是一种起源于鼻咽部的上皮性恶性肿瘤。鼻咽癌的发病具有独特的地域分布格局,中国患者约占所有患者的50%。鼻咽癌的主要治疗方法包括放疗、化疗和免疫治疗。其中,放射治疗具有重要作用。与鼻咽癌 (NPC) 放疗的急性副作用相关的遗传变异在很大程度上仍然未知。本研究进行了两阶段全基因组关联分析,包括总共 1084 名患者。发现5个 SNP(rs6711678、rs4848597、rs4848598、rs2091255 和 rs584547)在验证后显示出统计学意义。在所有5个 SNP 的突变次要等位基因携带者中,放射治疗毒性更为严重。分层分析进一步表明 rs6711678、rs4848597、rs4848598 和 rs2091255 与 EBV 阳性、晚期(III 和 IV)同时接受同步放化疗和诱导/辅助化疗的患者的皮肤毒性相关,OR 值范围为 1.92 至 2.66 。对于 rs584547,在发现(P = 1.27 × 10−6,OR = 1.55)和验证(P = 0.002,OR = 4.20)队列中,发现 A 等位基因携带者吞咽困难的发生率很高。此外,建立了综合遗传和临床因素对皮肤反应和吞咽困难的预测模型。受试者工作特征 (ROC) 曲线的曲线下面积 (AUC) 值为 0.657(皮肤反应)和 0.788(吞咽困难)。总之,该研究发现5个SNP(rs6711678、rs4848597、rs4848598、rs2091255 和 rs584547) 是接受放疗的 NPC 患者皮肤毒性和吞咽困难的新风险位点。
