BACKGROUND/AIM: This study was designed to clarify the value of routine alpha-fetoprotein (AFP) testing for patients with gastric cancer (GC).
A total of 905 patients with newly diagnosed GC and available pretreatment carcinoembryonic antigen (CEA), cancer-related antigen 19-9 (CA19-9), and AFP data from 2010 to 2016 were collected for comparison of tumor stage and survival.
In total, 139 patients (15.4%), 155 patients (17.1%), and 27 patients (3.0%) had elevated CEA, CA19-9, and AFP levels, respectively. The c-index values of elevated AFP levels in predicting stage IV disease and the 1-year mortality rate were 0.564 (95%CI=0.520-0.608) and 0.594 (95%CI=0.553-0.635), respectively, which were significantly lower than those of CEA (0.673 and 0.665) and CA19-9 (0.619 and 0.618).
Elevated AFP is rare in patients with newly diagnosed GC. Routine AFP sampling would not provide a higher survival prediction in GC patients than CEA or CA19-9.
背景/目的：本研究旨在阐明常规甲胎蛋白（AFP）检测对胃癌（GC）患者的价值。
共收集了 905 例 2010 年至 2016 年间新诊断为 GC 且术前癌胚抗原（CEA）、癌相关抗原 19-9（CA19-9）和 AFP 数据可用的患者，用于比较肿瘤分期和生存情况。
共有 139 例（15.4%）、155 例（17.1%）和 27 例（3.0%）患者的 CEA、CA19-9 和 AFP 水平升高。升高的 AFP 水平预测 IV 期疾病和 1 年死亡率的 c 指数值分别为 0.564（95%CI=0.520-0.608）和 0.594（95%CI=0.553-0.635），明显低于 CEA（0.673 和 0.665）和 CA19-9（0.619 和 0.618）。
新诊断的 GC 患者 AFP 升高罕见。与 CEA 或 CA19-9 相比，常规 AFP 采样并不能为 GC 患者提供更高的生存预测。
