摘 要:目的通过整合源自中国国内三家大样本胃癌数据库的资料,了解我国胃癌诊治研究的现状。 方法收集中山大学肿瘤防治中心、中国医科大学附属第一医院和天津医科大学肿瘤医院自2000年1月至2012年12月期间行胃癌手术切除并具有完整随访信息的患者临床病理资料并进行回顾性分析。采用Kaplan-Meier法计算患者生存率,行单因素分析及Cox多因素风险回归模型分析患者预后。 结果本研究纳入病例8 338例,其中中山大学肿瘤防治中心2 977例(35.7%),中国医科大学附属第一医院3 043例(36.5%),天津医科大学肿瘤医院2 318例(27.8%)。男性5 852例,女性2 486例,男女比例2.4∶1.0。年龄15~89岁(中位年龄59岁)。全组早期胃癌(T1NanyM0)占11.5%(956/8 338)。肿瘤位于贲门胃底部2 226例(26.7%),胃体部1 637例(19.6%),胃窦部3 739例(44.9%),全胃癌736例(8.8%)。肿瘤最大径中位数为(4.5±2.8)cm。Lauren肠型3 448例(41.4%),弥漫型4 890例(58.6%)。全胃切除1 975例(23.7%),胃次全切除6 363例(76.3%)。7 707例(92.4%)行根治性切除术,631例(7.6%)行姑息切除术。按AJCC/UICC的第7版胃癌TNM分期,ⅠA期802例(9.6%),ⅠB期735例(8.8%),ⅡA期695例(8.3%),ⅡB期1 507例(18.1%),ⅢA期1 247例(15.0%),ⅢB期1 342例(16.1%),ⅢC期1 583例(19.0%),Ⅳ期427例(5.1%)。平均淋巴结送检数目(21.0±13.1)枚,其中淋巴结送检数目〉 15枚者5 761例(69.1%)。全组患者1、3、5、10年生存率分别为83.0%、56.8%、49.1%和43.0%;根治性切除患者1、3、5、10年生存率分别为84.9%、59.5%、51.7%和45.3%;不同病理分期患者的5年生存率分别为:Ⅰ A期93.8%,ⅠB期80.8%,ⅡA期70.8%,ⅡB期59.6%,ⅢA期44.4%,ⅢB期32.9%,ⅢC期18.9%,Ⅳ期10.2%。Cox多因素风险回归模型显示:年龄、肿瘤部位、肿瘤大小、LauObjectiveTo elucidate the current diagnosis and treatment status of gastric cancer in the Chinese population based on three high volume databases. MethodsClinical and pathological data of patients who underwent gastric cancer resection with complete follow-up information between January 2000 and December 2012 from Sun Yat-sen University Cancer Center, The First Affiliated Hospital of China Medical University and Tianjin Medical University Cancer Hospital were retrospectively analyzed. The overall survival rate was calculated by Kaplan-Meier method. The prognostic risk factors were analyzed by using Cox proportional hazards model. ResultsA total of 8 338 cases were enrolled into the study, including 2 977 cases (35.7%)from Sun Yat-sen University Cancer Center, 3 043 cases (36.5%)from The First Affiliated Hospital of China Medical University and 2 318 cases (27.8%)from Tianjin Medical University Cancer Hospital. There were 5 852 male cases and 2 486 female cases with a ratio of 2.4∶1.0. The age of patients was from 15 to 89 years old (median 59 years old). The ratio of early gastric cancer(T1NanyM0)was 11.5% (956/8 338). There were 2 226 gastric cancer cases (26.7%)originating from the fundus and cardiac region, 1 637 cases (19.6%)from the body, 3739 (44.9%)cases from the antrum, and 736 cases (8.8%)from the whole stomach. The median maximal tumor diameter was (4.5±2.8)cm. Based on the Lauren classification, 3 448 cases (41.4%)were intestinal type and 4 890 cases(58.6%)diffuse type. A total of 1 975 cases (23.7%)and 6 363 cases (76.3%)underwent complete and subtotal gastrectomy respectively. The majority of patients (7 707 cases, 92.4%)underwent radical gastric resection, while 631 cases (7.6%)palliative resection. According to AJCC/UICC seventh edition of gastric cancer TNM staging system, 802 patients (9.6%)were stage ⅠA, 735 patients (8.8%)stage ⅠB, 695 patients (8.3%)stage ⅡA, 1 507 patients (18.1%)stage ⅡB, 1 2
