Abstract：
INTRODUCTION:Gastrointestinal stromal tumours (GIST) make up 2% of gastrointestinal tumours. Surgery is the only treatment method in localised cases. The laparoscopic approach has increased over the last few years. We present our experience in the treatment of GIST. MATERIAL AND METHODS:A total of 40 patients with 45 GIST had been subjected to surgical treatment between 1997 and 2010. Data was retrospectively collected on, demographic characteristics, location and tumour biology, diagnosis, type of surgery and the results of that surgery. RESULTS:A total of 24 males and 16 women, with a mean age of 66.7 years, were treated. The location was gastric in 24 cases (60%), small intestine in 13 (32.5%), colon in 2 (5%) and oesophagus in 1 case (2.5%). Laparotomy was performed in 27 cases, 12 by laparoscopy (1 thoracoscopy), and 1 endoscopic sigmoid tumour resection. Four cases (10%), all after laparotomy, had recurred after a median follow-up of 31 months (2-120), and 2 patients of the laparotomy group died due to their cancer. After a univariate analysis, the prognostic factors for a laparoscopic recurrence were: tumour size (P=.0001), mitosis number (P=.001), being a locally advanced tumour (P=.01) and a ruptured tumour (P=.002). Only size remained as a prognostic factor after the multivariate analysis (P=.029; RR 1.363; 95% CI; 1.033-1.799). The presence of a locally advanced tumour was shown to be significant in the univariate analysis, while there were no significant factors after the multivariate analysis. CONCLUSIONS:Correct preoperative staging is essential for deciding which surgical approach to employ.
