Is it possible to differentiate gastric GISTs from gastric leiomyomas by EUS?

Table 3 Sensitivity, specificity and positive and negative predictive values of the EUS features that differentiate GISTs from leiomyomas in the stomach (%)

EUS features	Sensitivity	Specificity	Positive predictive value	Negative predictive value
Echogenicity in comparison with the surrounding muscle echo	58.7	100	100	26.9
Homogeneity	80.4	85.7	97.4	40.0
Echogenic foci	89.1	57.1	93.2	44.4
Marginal halo	78.3	85.7	97.3	37.5
Of the above 4 features
≥ 1	97.8	57.1	93.8	80.0
≥ 2	89.1	85.7	97.6	54.5
≥ 3	84.8	85.7	97.5	46.2
All	34.8	100	100	18.9
