Methods The clinical data and the pathological findings, including immunohistochemical staining, of 17 patients with malignant colorectal mesenchymoma admitted from Jan 1990 to Mar 2005 were retrospectively analyeed. All the patients were followed up carefully. Results All the patients underwent operation, and all the tumors were proved malignant pathologically. In 6 cases left hemicolectomy was done, in 3 cases right hemicolectomy was done, in 2 cases the treatment was local resection from the rectum, and 6 patients received Mile's resection. The 1, 3 and 5-year overall survival rates for 17 patients with the total resection of tumor were 100%, 70.6% and 47.1%, respectively. The median survival time for 17 patients was 52 months. The final diagnosis of malignant GIST depended on the pathological examination, but the most worthwhile diagnostic criterion was the presence of CD117 and CD34 cells. Conclusion Since the prognosis is very poor, radical hemicolectomy is the principal treatment, and comprehensive treatment is necessary to improve clinical result.
