A diagnostic model based on clinical and enhanced computed tomography features to identify gastric schwannoma and gastric stromal tumor of different sizes: a multi-institution retrospective study.

ABSTRACT:

Background

The preoperative diagnosis of gastric stromal tumor (GST) and gastric schwannoma (GS) is of great significance for the selection of surgical methods. However, their similar clinical and imaging findings make it challenging to distinguish between the two tumors, and thus misdiagnosis occurs frequently before surgery. This study aimed to investigate the value of clinical data and enhanced computed tomography (CT) features in the differential diagnosis of GST and GS by a multi-institution retrospective analysis, for large (≥5 cm) and small (<5 cm) tumors.

Methods

This study involved 493 patients with GST and 102 patients with GS. The enhanced CT imaging data and clinical characteristics of the participants were analyzed, including the complete clinical and imaging da
