Abstract:
Objective To analyze the clinical characters,therapeutic effect of gastrointestinal stromal tumors (GIST),the effects of surgical approach and imatinib adjuvant therapy on it.Methods From January 2004 to April 2010,the clinical data of 214 patients with primary GIST were retrospectively analyzed.The effects of surgical approach and imatinib on the survival of the GIST patients were compared.Count data were analyzed by chi-square test,and the survival rates were analyzed with the life table method and Kaplan-Meier curve.Results A total of 214 GIST patients'survival rates of 1-year,3-year,5-year were 93.0％,87.0％ and 80.0％.According to the risk classification of National Institutes of Health,the differences of overall survival rates after surgery were statistically significant (x2 =22.058,P＜0.05).The differences of survival rate among different nuclear division number were statistically significant (x2=26.599,P＜0.05).The survival rate of pathological nuclear division number over 10/50 high power field (HPF) was the lowest.The overall survival rate of patients with gastrointestinal GIST was higher than patients with extragastrointestinal GIST,and the difference was statistically significant (x2 =68.139,P ＜ 0.05).After complete resection of the tumor,the survival rate of patients with local recurrence was higher than those with widely recurrence,and the difference was statistically significant (x2 =4.409,P＜ 0.05).After complete resection of the tumor,the survival rate of patients taking imatinib was higher than that of patients not taking imatinib.Conclusions The surgical treatment was the main therapy for GIST.Complete resection of the tumor and taking imatinib after surgery could improve the prognosis and the survival rate of the GIST patients.
