Risk Factors Of Cancer Recurrence In Stomach After Non-curative ER For Early Gastric Cancer

Objective : To analyze the risk factors of cancer recurrence in stomach after non-curative resection of early gastric cancer(EGC).Methods:From October 2008 to June 2018,endoscopic treatment for early gastric cancer was performed in the Endoscopy Center of Shanghai Renji Hospital.A retrospective study is performed on the data of patients who selected to be followed up after non-curative resection and the univariate logistic regression was used to analysis of 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 12 cases of cancer recurrence in the stomach(11 patients in total).The univariate logistic regression analysis showed lymphatic vessel invasion(P=0.03,OR=8.63,95 %CI: 1.24-60.04)and eCura high-risk grading(p=0.045,OR=7.31,95% CI: 1.05-51.1)were risk factors for cancer recurrence in the stomach.Conclusion:The routine eCura grading assessment can be considered after non-cure resection.Patients with high risk of lymphatic vessel invasion or high-risk eCura category are not recommended for follow-up;patients in 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.
