Abstract:
Objective:To investigate the relationship between the distance from the upper and lower resection margin and the gastric cancer patients with R0 resection and no distant metastasis.Methods:Retrospective analysis of 281 patients with gastric cancer in our hospital,the relationship between the age,sex,tumor size,tumor size,vascular invasion,lymph node metastasis,TNM stage,type of gastric cancer,tumor location and operation mode was analyzed.To compare the survival time of patients with different upper and lower margins.Results:The increase of the distance from upper resection margin was significantly related to the tumor size＞5 cm,TNM stage,type of gastric cancer,tumor location,and the difference was statistically significant(P＜0.05);The distance of lower resection margin was significantly correlated with tumor size＞5cm,vascular invasion,lymph node metastasis and TNM stage,type of gastric cancer,and the difference was statistically significant (P＜0.05);Themedian survival timein patientsof upper resection marginr□3cm with 48 months of the 5-year follow-up period was significantly higher than that in patients of the resection margin＞3cmwith 46 months (P＜0.001).Themedian survival timein patientsof lower resection margin□3cm with 45 months of the 5-year follow-up period was significantly higher than that in patients of the resection margin＞3cm with 44 months (P＜0.001).Conclusion:Gastric cancer postoperative upper and lower resection margin was significantly related with tumor size,TNM staging factors,and the median survival time of upper and lower resection margin＞5 cm was significantly lower than that of the resection margin3 cm.
