title: Clinical impact of EUS-guided Trucut biopsy results on decision making for patients with gastric subepithelial tumors ≥ 2 cm in diameter.
abstract: BACKGROUND
  Preoperative pathologic diagnosis of a gastric subepithelial tumor (SET) may improve clinical decision making. However, the clinical impact of EUS-guided Trucut biopsy (EUS-TCB) data on decision making in patients with a gastric SET has not been assessed.
  
  
  OBJECTIVE
  To evaluate the impact of EUS-TCB information on the clinical management of patients with a gastric SET.
  
  
  METHODS
  Retrospective review of prospectively collected data.
  
  
  METHODS
  Tertiary referral center.
  
  
  METHODS
  Sixty-five patients with gastric SETs 2 cm or larger in diameter.
  
  
  METHODS
  EUS-TCB.
  
  
  METHODS
  The number of patients for whom treatment plans were changed because of EUS-TCB results.
  
  
  RESULTS
  Nine SETs were not punctured by the TCB needle because of technical problems, and we were unable to obtain adequate subepithelial tissue from 19 SETs. Treatment plans were changed for 18 of 65 patients (27.7%). The changes were avoiding unnecessary resection (7 benign SETs ≥ 3 cm in diameter), scheduling for definitive treatment (6 GI stromal tumors and 1 carcinoid tumor), and modifying the surgical field (3 large GI stromal tumors and 1 carcinoma). When we assessed treatment plans relative to tumor location, we found that avoiding unnecessary resection was associated with the presence of cardiac SETs.
  
  
  CONCLUSIONS
  Retrospective study with a small number of patients.
  
  
  CONCLUSIONS
  EUS-TCB changed or influenced management decisions in 18 of 65 patients (27.7%) with gastric SETs. Patients could receive proper and tailored surgery, medical treatment, or surveillance according to size and location of SETs with EUS-TCB.
