‘Retrospective Analysis of Various Ct Imaging Features of Gist and Their Correlation with Histopathology’

Abstract

Gastro-intestinal stromal tumors are the commonest mesenchymal tumors of the gastrointestinal tract with variable malignant potential. Its origin can be anywhere between esophagus and rectum along with a variety of growth patterns. Contrast enhanced CT study of the abdomen is the most common imaging modality used for GIST evaluation in tertiary care centers. Although histopathological examination of the tumour sample is the gold standard for differentiating benign GIST from malignant GIST, it is possible to arrive at a diagnosis with a reasonable accuracy using imaging features alone. We conducted a retrospective study in our tertiary care centre taking into consideration the statistically significant CT imaging features and we assessed if there were any positive or negative associations of those factors with the final HPE diagnoses of GIST benign or malignant.
