THE CAPABILITIES OF COMPUTED TOMOGRAPHY AND ULTRASOUND DIAGNOSIS IN PREOPERATIVE EVALUATION OF INTRAMURAL GASTRIC CANCER INVASION
1Kharkiv Regional Clinical Cancer Center; 2Kharkiv Medical Academy of Postgraduate Education
The capabilities of x−ray computed tomography and ultrasonography in determining the stage of intramural invasion of gastric cancer are presented. Main features of intramural invasion were distinguished and systematized (various degrees of the wall thickening, impaired differentiation of its layers, complete or partial, depending on T stage). Investigation of 36 patients with different stages of gastric cancer (according to TNM) showed that transabdominal ultrasonography was more accurate and specific method vs. x−ray computed tomography in diagnosis intramural gastric cancer invasion, preferably at earlier stages of development, although it a number of cases differentiation of T3 and T4 stages was difficult. Computed tomography allowed more distinct vs. ultrasonography visualization of the anatomical structures lying outside the gastric wall. The analysis showed the advisability of complex application of methods of x−ray computed tomography and ultrasonography at pre−operative evaluation of patients with suspected cancer of the stomach.
