The purpose of this study was to identify clinicopathologic factors associated with overall survival (OS) in early T stage gastric cancer in a Western population.
Patients with stage T1 or T2 gastric or gastroesophageal adenocarcinoma who had undergone upfront gastrectomy from 1995 to 2013 were identified in an institutional database.
We identified 121 patients with pathologic stage T1 or T2 tumors (49 [41%] T1a; 49 [41%] T1b; and 23 [19%] T2) who underwent R0 resection without preoperative treatment. Of these, 53% were white, 9% African American, 17% Hispanic, and 22% Asian. The median follow-up was 5.7 years, and the 5-year OS rate was 89% (98%, 93%, and 66% for patients with T1a, T1b, and T2 tumors, respectively). Univariate analysis revealed a higher risk of death in patients with T2 tumors and those of African American race. On multivariate analysis, T2 stage was the only variable independently associated with OS (hazard ratio, 2.80; 95% confidence interval, 1.11-7.12; P = 0.03).
In this study of a Western population of patients with T1 or T2 gastric cancer, T2 stage was associated with diminished OS, whereas nodal status and race were not. J. Surg. Oncol. 2016;114:602-606. © 2016 Wiley Periodicals, Inc.
本研究旨在确定西方人群中早期T分期胃癌总生存(OS)相关的临床病理因素。
在一个机构数据库中识别出1995年至2013年间接受了初次胃切除术的T1或T2期胃或胃食管腺癌患者。
我们确定了121例病理分期为T1或T2期肿瘤的患者(49例[41%]为T1a;49例[41%]为T1b;23例[19%]为T2),他们接受了R0切除且未接受术前治疗。其中,53%为白人,9%为非裔美国人,17%为西班牙裔,22%为亚裔。中位随访时间为5.7年,5年总生存率为89%(T1a、T1b和T2期肿瘤患者的5年总生存率分别为98%、93%和66%)。单因素分析显示,T2期肿瘤患者和非裔美国人死亡风险更高。多因素分析显示,T2期是唯一与总生存独立相关的变量(风险比,2.80;95%置信区间,1.11 - 7.12;P = 0.03)。
在这项针对西方T1或T2期胃癌患者的研究中,T2期与总生存降低相关,而淋巴结状态和种族则不然。《外科肿瘤学杂志》2016年;114:602 - 606。© 2016威利期刊公司
