RESULTS: =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.
