Gastric remnant cancer patients had a better prognosis than upper-third gastric cancer patients in a case-control study after surgical treatment

Abstract

Background. The aim was to compare the clinicopathological features and prognostic outcomes of gastric remnant carcinoma patients with those of patients with upper-third gastric cancer.
Methods. Clinical data extracted from 112 gastric remnant carcinomas and 367 upper-third gastric cancer patients were analyzed to explore the clinicopathologic differences between two groups. After radical resection, prognostic difference between them was evaluated through a 1:2 matched case-control study.
Results. The pattern of gastric remnant carcinomas showed a male predominance. Undifferentiated type histology, depth at T4 stage and distant metastases were more frequent in gastric remnant carcinomas than in upper-third gastric cancers (P >0.05). The radical resectability of gastric remnant carcinomas was lower and the multi-visceral resectabilitiy was relatively higher than the other group (P = 0.00). Gastric remnant carcinomas trended to have a higher incidence of metastases to either mesojejunum or lower mediastinal lymph nodes than upper-third gastric cancers, but patient survival was not significantly different. In the case-control study, gastric remnant carcinomas had a better prognosis than upper-third gastric cancers after radical resection when the clinicopathologic features and surgical treatment were matched.
Conclusions. Although there was no significant prognostic distinction between gastric remnant carcinomas and upper-third gastric cancer, after radical surgical treatment, patients with the former had an even better prognosis.
