BACKGROUND AND AIMS: There is no evidence of postoperative metastasis of gastric @entity674 ( @entity674 ) smaller than 2 cm. The aim of this study was to evaluate the clinical usefulness of endoscopic ultrasound guided fine needle aspiration (EUS-FNA) for @entity1819 ( @entity75 ) smaller than 2 cm. @entity1 AND METHODS: Using a prospectively maintained EUS-FNA database, 90 consecutive EUS-FNAs of gastric hypoechoic solid @entity75 smaller than 2 cm diagnosed by EUS were evaluated retrospectively. The reference standards for the final diagnosis were surgery (n=44) and/or clinical follow-up (n=46) using esophagogastroduodenoscopy (EGD), CT, and/or ultrasonography (US). Additionally, immunophenotyping of specimens obtained by EUS-FNA and surgical resection specimens were compared. RESULTS: The diagnostic rate of EUS-FNA for gastric hypoechoic solid @entity75 smaller than 2 cm was 73% (66/90). Histological diagnosis of EUS-FNA showed 47 (52%) malignant @entity75 (44 @entity674 , 1 @entity5 , and 1 @entity706 ), 19 (21%) benign @entity75 (14 @entity2909 , 4 @entity788 ), and 24 (27%) indeterminate @entity75 . In 44 surgically resected cases, the diagnostic accuracy of EUS-FNA using immunohistochemical analysis was 98% (43/44). There were no complications. Appropriate management was performed in 65 out of 66 @entity75 (98%) diagnosed by definitive EUS-FNA. After surgery, there was no recurrence of malignant @entity75 . CONCLUSIONS: EUS-FNA is an accurate and safe method in the pre-therapeutic diagnosis of @entity1819 smaller than 2 cm. EUS-FNA for @entity1819 smaller than 2 cm is a promising way to permit early management of @entity1 with @entity1819 including GIST.
