Risk factors of cancer recurrence in stomach after non-curative endoscopic resection for early gastric cancer

Objective To analyze the risk factors of cancer recurrence in stomach after non-curative endoscopic resection for early gastric cancer (EGC). Methods Data of 59 patients with early gastric cancer, who underwent non-curative resection at endoscopy center of Shanghai Renji Hospital from October 2008 to June 2018, were analyzed with the univariate Logistic regression for the risk factors of cancer recurrence in the stomach. Results The follow-up period ranged from 4 to 77 months, with the median time of 40 months. There were 11 cases of cancer recurrence in the stomach. The univariate Logistic regression analysis showed lymphatic vessel invasion (OR=8.63, 95%CI: 1.24-60.04, P=0.030) and eCura high-risk grading (OR=7.31, 95%CI: 1.05-51.10, P=0.045) were risk factors for cancer recurrence in the stomach. Conclusion The routine eCura grading assessment can be considered after non-cure resection. Patients with lymphatic vessel invasion or high-risk eCura category are not recommended for follow-up; patients with low-risk eCura grading can be followed up by regular endoscopy and attention should be paid to whether there are abnormalities around the original lesion.
