Abstract: To explore the prognostic factors of remnant gastric cancer (RGC) and prognostic difference compared RGC with proximal stomach cancer with consistent TNM stage and treatment. Methods: The clinical data of 83 patients with RGC who underwent radical resection at the Cancer Institute and Hospital of Tianjin Medical University between July 1991 and July 2008 were analyzed. A paired case control study compared RGC with 83 proximal stomach cancers. Results: Tumor diameter, TNM stage, depth of invasion, and lymph node metastasis were important prognostic factors of RGC ( P < 0.05 ), whereas TNM stage and depth of invasion were independent prognostic factors ( P < 0.05 ). In the case control study, combined organ resection of RGCs were more frequent than proximal stomach cancers ( P = 0.022 ). The survival rate and median survival for RGC were higher than those of proximal stomach cancer patients ( P = 0.042 ). Conclusion: RGCs have better prognosis than proximal stomach cancer after radical resection.
