Objective:
To investigate the independent prognostic factors of long-term survival for gastric stump cancer after radical resection.
Methods:
The clinicopathological and follow-up data of 63 patients with gastric stump cancer undergoing surgical treatment from January 1996 to December 2006 in our hospital were analyzed retrospectively, including age, gender, types of reconstruction, tumor location, histological types, TNM stages, surgical treatment, prognosis and etc. The survival was estimated using Kaplan-Meier method and compared using log-rank test. The effect of independent factors on prognosis was determined by Cox regression multivariate analysis.
Results:
Radical resection was performed in 35 patients, including combined multiple organ resection (n=16). Surgery was palliative in 28 patients. All the 63 patients were followed up. The median survival time of these 63 patients was 21 months, and the overall 1-, 3-, 5-year survival rates were 76.2%, 31.7% and 18.8%, respectively. Univariate and multivariate analysis showed that surgical procedure, clinical stage and histological type were independent prognostic factors of gastric stump cancer, while age, gender, type of reconstruction and tumor location were not significantly correlated with prognosis.
Conclusions:
Radical resection, clinical stage and histological type are main prognostic factors for gastric stump cancer. Radical resection is an effective way to prolong the postoperative survival time in patients with gastric stump cancer, especially in the early stage.
