RCT of EFTR Versus STER for GIST Treatment
Recruiting now · Not applicable
Conditions studied: Small Size Gastrointestinal Stromal Tumors, GIST
In brief
Endoscopic resection has been increasing utilized as the treatment for small size gastrointestinal stromal tumors (GIST), of which the best resection method has not been identified. We aim to compare the outcomes of endoscopic full thickness resection (EFTR) versus submucosal tunnelling endoscopic resection (STER) for clinical small gastric GIST. We hypothesize that EFTR could achieve better complete margin negative resection than STER without increase in adverse event. This is an international multi-center double blinded randomized controlled trial involving four high volume centers from Hong Kong, mainland China, India and Japan. Adult patients with clinical 1.0-3.Scm gastric GIST undergoing endoscopic resection would be recruited. Patients would be randomized to undergo EFTR (intervention) or STER (Control) by expert endoscopists under general anaesthesia according to well published methods.

Who can join
Age: 18 and older, up to 75. Sex: any. Healthy volunteers: not accepted.
You may qualify if…
- Presence of gastric subepithelial tumor on diagnostic upper endoscopy, and
- Diagnostic EUS and CT scan with intravenous contrast suspicious of GIST arising from muscularis propria layer, size with maximum diameter >=1.0cm and <= 3.5cm, and
- Absence of high risk features, including irregular margins, invasion to surrounding organs, lesion hypervascularity, and
- Endoscopic morphology and location deemed feasible with both EFTR and STER by an expert endoscopist, or
- Histological confirmation of GIST through EUS guided fine needle biopsy (Optional, based on recommendation from guidelines)
You may not qualify if…
- Patients with tumors deemed not suitable for endoscopic resection (Either EFTR or STER), due to unfavourable location, high risk morphology, or any other reasons.
- Patients with multiple tumors.
- Patients unable or unwilling to provide consent.
- Previous esophageal or gastric surgery.
- Patients with significant cardiorespiratory comorbidities which may limit their ability to undertake general anesthesia for the procedure, including ASA grade III or above.
- Pregnant women or those planning pregnancy or breastfeeding women.
- Uncorrectable coagulopathy defined by international normalized ratio (INR) > 1.5 or platelet count < 50000/µl.
- Patients on double anti-platelet agents or anti-coagulation (Warfarin, heparin or other direct oral anticoagulants)
