ABSTRACT
<p><b>OBJECTIVE</b>To 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.</p><p><b>METHODS</b>The 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.</p><p><b>RESULTS</b>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%(5711/29290) in 2014 to 19.0%(6081/32050) in 2015 and 20.0%(5395/27000) in 2016. Significant difference was found among them (χ=9.553, P=0.008). Significant differences existed not only in the proportion of early gastric cancer between the south (20.9%, 7618/ 36518) and the north (18.5%, 9569/51822) of China (χ=78.468, P=0.000), but also between the general (20.4%, 11991/58672) and the specialized (17.5%, 5196/29668) hospitals(χ=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 (χ=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%, 2312/10954) (χ=451.526, P=0.000), and between the hospitals with more than 800 gastric cancer patients per year (28.9%, 3434/11884) and those with less than 800 gastric cancer patients (21.1%, 1121/5303)(χ=113.270, P=0.000). 37.1%(5270/14186) 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 (χ=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(χ=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) (χ=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 (χ=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%(1825/14377) 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.</p><p><b>CONCLUSION</b>The data report of China Gastrointestinal Cancer Surgery Union partly reflects the epidemiologic characteristics, current status of diagnosis and treatment of early gastric in China.</p>
