摘要 目的基于中国胃肠肿瘤外科联盟(联盟)数据,探讨中国早期胃癌的流行病学特点和诊治现状。方法联盟采用调查问卷的形式,向各联盟成员单位发放收集胃癌及结直肠癌相关数据的幻灯片,各单位根据要求按照不同年度,将填写完毕后的幻灯片发送至联盟邮箱(gi_union@foxmail.com),由联盟数据汇总小组进行资料数据汇总分析。结果2014—2016年期间,联盟收集到来自全国85家中心的285份数据调查幻灯片,其中一线城市医院19家,肿瘤专科医院19家,年诊治胃癌患者超过800例的医院24家;共收集胃癌手术病例总量88 340例,其中早期胃癌17 187例(部分中心数据空项,后同)。2014年、2015年和2016年,早期胃癌患者占当年整体胃癌人群的比例分别为19.5%(5711/29 290)、19.0%(6081/32 050)和20.0%(5395/27 000),差异有统计学意义(χ2 = 9.553,P = 0.008)。以我国秦岭淮河为界,南方的早期胃癌患者占外科就诊胃癌患者的比例为20.9%(7618/36 518),北方为18.5%(9569/51 822),差异有统计学意义(χ2 = 78.468,P = 0.000)。肿瘤专科医院就诊的早期胃癌患者占外科就诊胃癌患者的比例为17.5%(5196/29 668),综合医院早期胃癌患者所占比例为20.4%(11 991/58 672),差异有统计学意义(χ2 = 107.473,P = 0.000)。73家上报胃癌数据的医疗中心中有19家(26.0%)常规将超声胃镜作为胃癌的常规分期诊断手段,其中综合医院有10家(17.5%,10/57),肿瘤专科医院有9家(56.2%,9/16),差异有统计学意义(χ2 = 9.721,P = 0.002)。早期胃癌患者17 187例中,接受内镜治疗的患者4555例,一线城市医院接受内镜治疗者占比为36.0%(2243/6233),非一线城市医院则为21.1%(2312/10 954),差异具有统计学意义(χ2 = 451.526,P = 0.000);在年诊治胃癌患者超过800例的医院中,接受内镜治疗者占比28.9%(3434/11 884),而年诊治胃癌患者不足800例的医院则占21.1%(1121/5303),差异也具有统计学意义(χ2 = 113.270,P = 0.000)。腹腔镜手术患者比例为37.1%(5270/14 186),在综合医院中,接受腹腔镜治疗者占比39.4%(3807/9651),在肿瘤专科医院中同期占比32.3%(1463/4535),差异具有统计学意义(χ2 = 68.244,P = 0.000);一线城市医院中,接受腹腔镜治疗者占比29.3%(1269/4328),非一线城市医院则为40.6%(4001/9858),差异具有统计学意义(χ2 = 163.480,P = 0.000);在年诊治胃癌患者超过800例的医院中,接受腹腔镜治疗者占比34.5%(3425/9929);而年诊治胃癌患者不足800例的医院则占43.3%(1845/4257),差异具有统计学意义(χ2 = 100.057,P = 0.000);在南方地区医院中,腹腔镜治疗比例为42.4%(2552/6016),而北方地区医院其比例为33.3%(2718/8170),差异具有统计学意义(χ2 = 124.296,P = 0.000)。早期胃癌的pT1a患者6975例(48.5%),pT1b患者7402例(51.5%);淋巴结转移率为12.7%(1825/14 377);其中pT1a患者的淋巴结转移率为5.7%(399/6975),pT1b患者淋巴结转移率19.3%(1426/7402);2014年、2015年和2016年各年度早期胃癌的淋巴结转移率分别为12.7%(510/4017)、12.2%(668/5494)和13.3%(647/4866)。结论中国胃肠肿瘤外科联盟的数据从一定程度上反映了我国早期胃癌的流行病学特点和诊治现状。 ObjectiveTo investigate the current status of diagnosis and treatment of early gastric cancer in China, based on the nationwide survey by China Gastrointestinal Cancer Surgery Union.MethodsThe union sent questionnaires on basic diagnosis and treatment data of gastric and colorectal cancer to all the centers of the union. Different centers collected and summarized their data by year and sent back the questionnaires to the e-mail of theunion (gi_union@foxmail.com) for summary.Results From 2014 to 2016, the union collected 285 questionnaires from 85 centers all over China. In these 3 years, a total of 88 340 cases of gastric cancer were summarized and there were 17 187 cases of early gastric cancer (part of the data was not available in some centers) . The proportion of early gastric cancer varied from 19.5% (5711/29 290) in 2014 to 19.0% (6081/32 050) in 2015 and 20.0% (5395/27 000) in 2016. Significant difference was found among them (χ2 = 9.553, P = 0.008) . Significant differences existed not only in the proportion of early gastric cancer between the south (20.9%, 7618/36 518) and the north (18.5%, 9569/51 822) of China (χ2 = 78.468, P = 0.000) , but also between the general (20.4%, 11 991/58 672) and the specialized (17.5%, 5196/29 668) hospitals (χ2 = 107.473, P = 0.000) . Ultrasonic endoscope was used as routine practice in 10 (17.5%, 10/57) general hospitals and 9 (56.2%, 9/16) specialized hospitals, and significant difference was found between them (χ2 = 9.721, P = 0.002) . A total of 4555 early gastric cancer patients received endoscopic therapy. The proportion of patients receiving endoscopic therapy was significantly different between the hospitals in the first-tier cities (36.0%, 2243/6233) and the other cities (21.1%, 2312/10 954) (χ2 = 451.526, P = 0.000) , and between the hospitals with more than 800 gastric cancer patients per year (28.9%, 3434/11 884) and those with less than 800 gastric cancer patients (21.1%, 1121/5303) (χ2 = 113.270, P = 0.000) . 37.1% (5270/14 186) of early gastric cancer patients received laparoscopic surgery. The proportion of patients receiving laparoscopic surgery was 39.4% (3807/9651) in general hospitals and 32.3% (1463/4535) in specialized hospitals, whose difference was significant (χ2 = 68.244, P = 0.000) . The proportion of patients receiving laparoscopic surgery was 29.3% (1269/4328) in the first-tier cities and 40.6% (4001/9858) in the other cities, whose difference was significant as well (χ2 = 163.480, P = 0.000) . The proportion of patients receiving laparoscopic surgery was significantly different between the hospitals with more than 800 gastric cancer patients per year (34.5%, 3425/9929) and those with less than 800 gastric cancer patients (43.3%, 1845/4257) (χ2 = 100.057, P = 0.000) , and between the hospitals in the south (42.4%, 2552/6016) and those in the north (33.3%, 2718/8170) of China (χ2 = 124.296, P = 0.000) . 48.5% (6975) of early gastric cancer patients staged pT1a and 51.5% (7402) staged pT1b. Lymph node metastasis was found in 12.7% (1825/14 377) of early gastric cancer. The lymph node metastasis rate of pT1a and pT1b was 5.7% (399/6975) and 19.3% (1426/7402) , respectively. The lymph node metastasis rate of early gastric cancer varied from 12.7% (510/4017) in 2014 to 12.2% (668/5494) in 2015 and 13.3% (647/4866) in 2016.ConclusionThe data report of China Gastrointestinal Cancer Surgery Union partly reflects the epidemiologic characteristics, current status of diagnosis and treatment of early gastric in China.
