    Abstract:
    OBJECTIVE: To explore the clinicopathological characteristics, efficacy, and prognostic factors for patients with duodenum gastrointestinal stromal tumor(GIST). METHODS: Clinicopathological and follow-up data of 80 patients with duodenum GIST in the Zhongshan Hospital from January 2000 to December 2013 were analyzed retrospectively. RESULTS: There were 38 male and 42 female patients with a median age of 54 years. The major symptoms were upper alimentary tract hemorrhage and abdominal pain. Thirty-nine patients received local tumor excision, 18 patients underwent segmental duodenectomy, 23 patients were subjected to pancreaticoduodenectomy, all these operations were R0 resection. Thirty patients received imatinib treatment after operation, and 11 among them had metastasis relapse. Recurrence-free survival rates of 1-, 3-, and 5-years were 96.2%, 90.6%and 78.6% retrospectively. Overall survival rates of 1-, 3-, and 5-years were 100%, 98.3% and 96.1%. Multivariate Cox analysis showed tumor size >5 cm, mitotic count >5 mitosis/50 HPF and intermediate/high NIH risk classification were associated with an increased risk of recurrence. The significant difference was not detected between the limited resection group and pancreaticoduodenectomy group in OS and RFS. CONCLUSIONS: Surgery is still the main treatment for duodenum GIST. The surgical program is mainly determined by the location and size of tumor. Imatinib therapy should be used if necessary.
