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

Condition(s) studied

Investigational drug(s) / intervention(s)

Laparoscopic resection: Laparoscopic surgery under general anesthesia

Study summary

Participants with gastrointestinal stromal tumors(GIST) were divided into favorable and unfavorable sites according to the anatomical site of the tumor, and this study aims to validate the overall postoperative morbidity and mortality rates between favorable site receiving laparoscopic resection of GIST and that of unfavorable site under the currently standard surgical therapy.

Eligibility

Primary outcome measure(s)

• 3-year disease free survival rate — 36 months
  Definition of recurrence and recurrence date The following situations are regarded as "recurrence" 1. Recurrence identified by any one image examination (X-ray, ultrasound, computed tomography, magnetic resonance imaging, etc.) and, if there are a variety of imaging examinations, results without contradiction determined "recurrence". The earliest date that the recurrence is found is defined as the "recurrence date". 2. For cases that lack the use of imaging or a pathological diagnosis, the date of diagnosing the occurrence of clinical recurrence based on clinical history and physical examination is defined as the "recurrence date". 3. For cases without imaging or clinical diagnosis but with a cytology or tissue biopsy pathological diagnosis of recurrence, the earliest date confirmed by cytology or biopsy pathology is considered the "recurrence date". 4. A rise in carcinoembryonic antigen or other associated tumor markers alone could not be diagnosed as a relapse.
