Comparison of Tumor Efficacy Safety in Laparoscopic Resection of Gastrointestinal Stromal Tumors Between Favorable and Unfavorable Site

This study is comparing surgical outcomes between two groups of patients who have a type of stomach tumor called a gastrointestinal stromal tumor (GIST) removed using laparoscopic (keyhole) surgery — those whose tumor is in an easy-to-reach location versus those whose tumor is in a harder-to-reach location — to understand safety and effectiveness across both groups. **You may be eligible if...** - You are between 18 and 75 years old - You have been diagnosed with a primary GIST of the stomach, confirmed by biopsy or imaging - Your tumor is 10 cm or smaller - Your general health is suitable for surgery (ECOG 0–1, ASA class I–III) - Your surgeon expects to achieve complete tumor removal by laparoscopy **You may NOT be eligible if...** - You are pregnant or breastfeeding - You have a severe mental disorder - You have had prior upper abdominal surgery (other than gallbladder removal) or prior gastric (stomach) surgery - You had a heart attack or stroke in the past 6 months - You have another active cancer in the past 5 years - Your surgery is an emergency (due to bleeding, obstruction, or perforation) - Your lung function is significantly reduced Talk to your doctor to see if this trial is right for you.
