| 1 | Prognostic factors and survival in patients with gastric stump cancer显示文摘AIM:To elucidate the clinicopathological characteristics and prognostic factors of gastric stump cancer(GSC).METHODS:The clinical data for 92 patients with GSC were collected at Fudan University Shanghai Cancer Center.The prognostic factors were analyzed with Cox proportional hazard models.RESULTS:GSC tended to occur within 25 years following the primary surgery,when the initial disease is benign,whereas it primarily occurred within the first15 years post-operation for gastric cancer.Patients with regular follow-up after primary surgery had a better survival rate.The multivariate Cox regression analysis revealed that Borrmann type?Ⅰ/Ⅱ(HR=3.165,95%CI:1.055-9.500,P=0.040)and radical resection(HR=1.780,95%CI:1.061-2.987,P=0.029)were independent prognostic factors for GSC.The overall 1-,3-,and 5-year survival rates of the 92 patients were78.3%,45.6%and 27.6%,respectively.The 1-,3-,and 5-year survival rates of those undergoing radical resection were 79.3%,52.2%,and 37.8%,respectively.The 5-year survival rates for stages?Ⅰ,Ⅱ,Ⅲ,andⅣwere 85.7%,47.4%,16.0%,and 13.3%,respectively(P=0.005).CONCLUSION:The appearance of GSC occurs sooner in patients with primary malignant cancer than in patients with a primary benign disease.Therefore,close follow-up is necessary.The overall survival of patients with GSC is poor,and curative resection can improve their prognosis. | Hua Huang Wei Wang Zhong Chen Jie-Jie Jin Zi-Wen Long Hong Cai Xiao-Wen Liu Ye Zhou Ya-Nong Wang | 2015 | World Journal of Gastroenterology2015，21，6： | 16 |
| 2 | Current status in remnant gastric cancer after distal gastrectomy显示文摘Remnant gastric cancer(RGC) and gastric stump cancer after distal gastrectomy(DG) are recognized as the same clinical entity. In this review, the current knowledges as well as the non-settled issues of RGC are presented. Duodenogastric reflux and denervation of the gastric mucosa are considered as the two main factors responsible for the development of RGC after benign disease. On the other hand, some precancerous circumstances which already have existed at the time of initial surgery, such as atrophic gastritis and intestinal metaplasia, are the main factors associated with RGC after gastric cancer. Although eradication of Helicobacter pylori(H. pylori) in remnant stomach is promising, it is still uncertain whether it can reduce the risk of carcinogenesis. Periodic endoscopic surveillance after DG was reported useful in detecting RGC at an early stage, which offers a chance to undergo minimally invasive endoscopic treatment or laparoscopic surgery and leads to an improved prognosis in RGC patients. Future challenges may be expected to elucidate the benefit of eradication of H. pylori in the remnant stomach if it could reduce the risk for RGC, to build an optimal endoscopic surveillance strategy after DG by stratifying the risk for development of RGC, and to develop a specific staging system for RGC for the standardization of the treatment by prospecting the prognosis. | Masaichi Ohira Takahiro Toyokawa Katsunobu Sakurai Naoshi Kubo Hiroaki Tanaka Kazuya Muguruma Masakazu Yashiro Naoyoshi Onoda Kosei Hirakawa | 2016 | World Journal of Gastroenterology2016，22，8： | 15 |
