Comparative analysis of the usefulness of endoscopic ultrasound guided fine needle aspiration (EUS-FNA) and mucosal incision assisted biopsy (MIAB) in the diagnosis of gastrointestinal stromal tumors (GIST) of the stomach.

Phase 1
Conditions
gastrointestinal stromal tumor
Registration Number
JPRN-UMIN000012169
Lead Sponsor
Department of Medicine and Bioregulatory Science, Graduate School of Medical Sciences, Kyushu University
Brief Summary

Results: A total of 47 patients were randomized to the MIAB group (n = 23) and EUS-FNA group (n = 24). There was no significant difference in the diagnostic yield of MIAB and EUSFNA (91.3% vs 70.8%, P = 0.0746). The complication rates of MIAB and EUS-FNA did not differ to a statistically significant extent. The mean procedure time in the MIAB group was significantly longer than that in the EUS-FNA group (34 vs 26 min, P = 0.0011).
