Risk Factors of Gastrointestinal Stromal Tumor Recurrence

Aim: Gastrointestinal stromal tumors (GIST) are the most common mesenchymal neoplasia of gastrointestinal system. Radical surgery with negative margin is important step for treatment GIST. The primary aim this study was to evaluate risk factors recurrence in patients who underwent diagnosis Secondary reveal that affect survival. Materials and Methods: data 28 GIST our clinic between January 2013 August 2019 were analyzed retrospectively. Patients preoperative radiological images, histopathological immunohistochemical findings noted. Results: Eighteen male, ten female. Median age 64.5 (range; 50-87). Twenty-six (92.2%) open 2 (7.1%) laparoscopic surgery. Fifteen (53.6%) located stomach, 10 (35.7%) small intestine, duodenum 1 (3.6%) multifocal. Mean tumor diameter 10.1 cm 0.5-21). number 5 (17.9%). Tumor necrosis, an organ other than high mitosis revealed a significant difference recurrence. In addition, large size statistical median follow-up period 26 (3-60) months. Necrosis type significantly shortened Conclusion: which we examined recurrence, it observed size, increased stomach mitoses found be It affecting survival times, secondary study, cell necrosis.
