Abstract
背景与目的肺癌的常用肿瘤标志物中,癌胚抗原(carcinoembryonic antigen, CEA)与糖类抗原125(carbohydrate antigen 125, CA125)、细胞角蛋白19片段(cytokeratin 19, CYFRA21-1)与鳞状细胞癌抗原(squamous carcinoma antigen, SCC)、神经元特异性烯醇化酶(neuron specific enolase, NSE)与胃泌素释放肽前体(pro-gastrin-releasing peptide, ProGRP)分别在肺腺癌、肺鳞状细胞癌和小细胞肺癌中有较高表达。本研究旨在通过对比多项肿瘤标志物异常(A组)和仅CEA和/或CA125异常(B组)的两组晚期肺腺癌患者,探讨多项肿瘤标志物异常在疗效评价和预测复发方面的价值。方法纳入中国医学科学院肿瘤医院的Ⅳ期肺腺癌初治病例,回顾性分析其临床数据,包括临床特征、治疗前的血清肿瘤标志物水平、疗效及无进展生存期。结果除CEA和CA125外,A组异常比率最高的肿瘤标志物是CYFRA21-1(93%),其次是NSE(36%)、SCC(13%)和ProGRP(12%)。多项肿瘤标志物异常的患者更易出现远处多部位转移(P < 0.001),治疗后的无进展生存期更短(中位时间5.3个月vs 7.3个月,P=0.016)。两组中进行维持治疗的患者均比未行维持治疗的患者复发风险低(P均 < 0.001)。结论多项肿瘤标志物异常患者复发风险高,维持治疗可降低复发风险。
