Tohoku J. exp. Med. 1985, 147 (4), 427-428-A new method was developed to diagnose the depth of cancer invasion using submucosography combined with special charcoal suspension containing mitomycin C, and applied to 8 cases of gastric cancer. Correct diagnosis of the depth of the cancer invasion was obtained in 7 of the 8 cases. As some cases of early gastric cancer can be treated endoscopically, it is important to know the condition of the invasion before any treatment is performed.
