ObjectiveTo investigate the influencing factors of short-term (1 year after operation) prognosis in elderly patients with primary gastric cancer after laparoscopic-assisted distal gastrectomy (LADG). MethodsA total of 60 elderly patients with primary gastric cancer receiving LADG were selected and divided into a survival group (49 cases) and a death group (11 cases) according to the results of 1-year postoperative follow-up. The basic data and surgical data of the two groups were compared, and the multivariate logistic regression model was used to analyze the factors influencing the short-term prognosis. ResultsPatients in the survival group had a lower complication incidence and a smaller tumor diameter than those in the death group. The proportions of patients with Borrmann type I/ II, highly differentiated histology, D2 lymph node dissection, no vascular invasion and postoperative adjuvant chemotherapy in the survival group were all higher than those in death group, with statistically significant differences (all P＜0.05). The result of multivariate logistic regression analysis showed that tumor diameter, Bommann type, histological type, as well as conditions of lymph node dissection, vascular invasion and postoperative adjuvant chemotherapy were independent influencing factors of the short-term prognosis in elderly patients with primary gastric cancer after LADG treatment (all P＜0.05). ConclusionTumor diameter, Bommann type, histological type, conditions of lymph node dissection and vascular invasion, and with or without postoperative adjuvant chemotherapy are all factors that affect the short-term prognosis of elderly patients with primary gastric cancer after LADG treatment.
