  • Abstract
  • Look Inside

 Preoperative angiography was made on 298 patients with gastric cancer. The depth of gastric cancer invasion was histologically classified into the following five groups : (1) mucosa (m), (2) submucosa (sm), (3) proper muscle layer (pm), (4) serosa (ss, se), (5) invasion to other organs (sei), and the accuracy in using angiography to diagnose the depth of invasion was assessed.

 Results :

 1. Diagnostic accuracy for the depth of cancerous invasion was 56.7% (55/97) by celiac angiography. Serosal invasion was correctly diagnosed in 83.5% (81/97) by celiac angiography.

 2. Diagnostic accuracy was 81.6% (93/114) by superselective angiography of the left gastric and common hepatic arteries. This rate was significantly higher than that of celiac angiography.

 3. Diagnostic accuracy was 87.4% (76/87) by superselective magnification angiography. Differentiation of invasion to mucosa and to submucosa was correctly diagnosed in 73.9% (17/23) by superselective magnification angiography.
