RESUMO
Objective To investigate the prognositic factors of small intestine stromal tumors after radical resection.Methods The clinicopathological data of 41 patients with small intestine stromal tumors admitted between January 2005 and December 2010 in Henan Tumor Hospital were analyzed restrospectively.Kaplan-Meier survival rate and COX regression were used to evaluate the prognostic factors.Results There were 22 males and 19 females.The age ranged from 22 to 78 years old (median,55years).Location of tumor included duodenum (n =12),jejunum and ileum (n =29).The 3-year survival rate was 22％ in those 16 cases who reported preoperative gastrointestinal bleeding and 65％ in those without GIT bleeding,the difference was statistically significant (P =0.0012).COX model showed that tumor size,the tumor location,recurrence and metastasis were independent risk factors associated with the prognosis in small intestine stromal patients (P ＜ 0.05).Conclusions The most common clinical presentation of these tumors was gastrointestinal bleeding.The tumor location,recurrence and metastasis and gastrointestinal bleeding was independent risk factors associated with the prognosis of small intestine stromal tumor patients.
