Abstract:

为探讨乳头状甲状腺癌术后复发的影响因素,回顾分析自2011年1月1日至2013年3月30日就诊的符合纳入标准且临床资料完整的69例乳头状甲状腺癌术后患者,男18例,女51例,平均年龄为40.17±12.97岁。所有患者均行甲状腺彩超、甲状腺功能测定、甲状腺球蛋白及抗体测定,且于未停用左旋甲状腺素状态下,甲状腺功能测定检查3次或以上,利用SPSS17.0对患者性别、年龄、肿瘤大小、手术方式、术后未停服左旋甲状腺素时促甲状腺激素(TSH)抑制程度、术后是否清甲治疗行单因素分析,多因素分析采用二分类Logistic回归分析术后复发的影响因素,绘制受试者工作特征曲线(ROC)曲线,用约登指数法确定术后TSH值评价肿瘤复发的阈值。P<0.05为差异有统计学意义。单因素分析结果表明,乳头状甲状腺癌术后复发与年龄、手术方式无明显相关性(分别为P=0.373、P=0.226),而与性别、肿瘤大小、术后TSH抑制程度、术后是否清甲治疗相关(分别为P=0.031、P=0.004、P=0.00001、P=0.00005),男性、肿瘤越大、术后TSH值较高、术后未清甲治疗的复发率较高。Logistic回归分析表明,肿瘤大小、术后行TSH抑制治疗过程中TSH抑制程度及术后是否行清甲治疗是肿瘤复发的影响因素。用约登指数法,确定术后TSH抑制程度评价肿瘤复发的临界点为0.2253mU/L。肿瘤直径较大、术后TSH值较高、术后未行清甲治疗对肿瘤复发影响较大,为肿瘤复发的可能危险因素。
