OBJECTIVE: To explore the clinicopathological characteristics and prognostic factors of gastric stump cancer(GSC).METHODS: The clinical data of 138 patients with GSC treated from January 1992 to July 2008 were reviewed and analyzed. The patients included 122 males and 16 females with a mean age of 61.5 years, and the mean interval between the initial operation and second diagnosis was 21.9 years.RESULTS: The endoscopy and pathological examination showed Borrmann III/IV in 127 (92.7%) patients and undifferentiated carcinoma in 115 (83.3%) patients. The resectability and radical resectability rate were 72.4% and 59.4%. The 1-, 3- and 5-year survival rates was 59.2%, 30.1% and 14.2%, respectively. The median overall survival time was 19.4 months. Univariate Log-rank test indicated that Borrmann type, histological type, tumor diameter, TNM stage, depth of invasion, number of metastatic lymph node, distant metastasis and option of treatment were significant prognostic factors for GSC. While TNM stage, depth of invasion, distant metastasis and option of treatment were prognostic factors on multivariable analysis. The median survival time of patients underwent radical resection was significantly longer (36 months) than that of patients received palliative resection (8 months, P < 0.05) and chemotherapy only (5 months, P < 0.05). Among patients with a tumor of T4 stage, the median survival time was statistically prolonged by combined evisceration (18.6 months) when compared with the patients received palliative surgery.CONCLUSIONS: TNM stage, depth of invasion, distant metastasis and option of treatment are independent prognostic factors for GSC. Early diagnosis and radical resection may play an important role in improving the prognosis of GSC.
