Trial summary

Gastrointestinal stromal tumors (GISTs) are the most common submucosal tumors (SMTs) of the stomach. The 2022 European Society of Oncology ESMO Diagnosis and Treatment Guidelines recommend that GISTs undergo biopsy with a clear pathological diagnosis and should be removed unless there are significant complications.

About this study

Official title: Comparison of Endoscopic Mucosal Cutting Biopsy and Endoscopic Ultrasound-guided-fine Needle Aspiration for Preoperative Pathological Evaluation of Gastric Submucosal Tumors

Gastrointestinal stromal tumors (GISTs) are the most common submucosal tumors (SMTs) of the stomach. The 2022 European Society of Oncology ESMO Diagnosis and Treatment Guidelines recommend that GISTs undergo biopsy with a clear pathological diagnosis and should be removed unless there are significant complications. But currently, the diagnostic rate of EUS-FNA for upper gastrointestinal subcutaneous lesions is less than 60%. In recent years, mucosal cutting biopsy (MCB) has become an effective method for diagnosing SMTs. Regardless of whether the SMTs are large or small, the application of MCB technology can quickly obtain pathological tissue under direct visualization, and its immunohistochemical pathological diagnosis rate is relatively satisfactory. MCB technology has great potential in the biopsy of SMTs, but there is currently no comparison of results between two technologies in randomized controlled trials. The purpose of this study is to design a randomized controlled trial to compare the diagnostic rates of EUS-FNA and MCB techniques for tissue pathology (including immunohistochemistry) of SMTs, in order to improve the diagnostic accuracy of SMTs in our hospital and improve patient prognosis.

Being tested
mucosal cutting biopsy, endoscopic ultrasound-guided-fine needle aspiration

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • mucosal cutting biopsyProcedure or surgery

    Under intravenous anesthesia, the patient inserted a gastroscopy (Olympus GIF-260J) through the mouth and used a disposable high-frequency cutting knife to cut open the surface mucosa of the tumor. Biopsy forceps were used to extract tissue that could be fully evaluated for pathological examination. Use a disposable hemostatic clip to suture the mucosal incision, and after thorough observation of the hemostasis, withdraw from the endoscope.

    (

  • endoscopic ultrasound-guided-fine needle aspirationProcedure or surgery

    1. EUS-FNA group: Standard (Endoscopic Ultrasonography-Guided Fine-Needle Aspiration) EUS-FNA technology was used, and electronic linear array ultrasound endoscopy (GF-UCT-260, Olympus, Japan) was used to scan and locate the lesion. Puncture needle (Boston Scientific, USA) was used for aspiration biopsy. The thickness of the puncture needle depends on the size, hardness, and location of the tumor.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Pathological diagnosis and immunohistochemical diagnosis

    Comparison of diagnostic yield between Mucosal Cutting Biopsy (MCB) and Endoscopic Ultrasonography-Guided Fine-Needle Aspiration (EUS-FNA) The diagnostic yield was defined as the percentage of lesions confirmed by a pathologic diagnosis involving immunohistological analysis.

    Measured: Pathological evaluation should be conducted immediately after specimen isolation
