摘要: Abstract Aims According to the recent Japanese Gastric Cancer Association's gastric cancer treatment guidelines, bursectomy is recommended for tumors penetrating serosa of posterior wall. However, there still little data show whether improves patient survival. The aim this study evaluate efficacy subserosa or serosa-positive in terms overall Method From April 2001 December 2006, 470 patients underwent curative resection macroscopically cancer. These were grouped according was performed not (bursectomy+/bursectomy−). Clinicopathological characteristics and incidence complications compared between groups. survival rates analyzed using a Cox proportional hazards model. Results There no significant difference morbidity mortality bursectomy+ bursectomy− In multivariable analysis survival, independent factor ( p  = 0.978). subgroup clinical pathological stage III IV, wall, did have effect on as well  = 0.582, 0.453, 0.532, respectively). propensity score-matched patients, showed  = 0.804). Conclusions Bursectomy unlikely improve with
