ABSTRACT
ObjectiveTo explore the value of virtual touch tissue quantification (VTQ) in evaluating Lauren classification of advanced gastric carcinoma.MethodsForty-one patients with gastric cancer proved by endoscopic biopsy performed preoperative VTQ examination,and the findings were compared with postoperative pathologic results via hematoxylin -eosin and Alcian Blue-Periodic Acid Schiff (AB-PAS) staining.ResultsIn 41 patients,26 cases were diagnosed as diffuse type and 15 cases as intestinal type by pathology after operation.The shear wave velocity(SWV) of diffuse type was higher than that of intestinal type [(1.72± 0.83)m/s vs (1.05± 0.66)m/s,t =2.819,P=0.008] measured by virtual touch tissue quantification (VTQ).According to the area under the ROC curve,the cut- off value of SWV in gastric cancer tissues for assessing the diffuse type was 1.045 m/s with a sensitivity of 80.8% and specificity of 73.3 % respectively.ConclusionsVTQ could be considered as a promising method to distinguish the Lauren classification in patients with advanced gastric carcinoma.
