[Clinico-pathologic comparison between early gastric cancer and early cancriform progressive cancer].

Clinico-pathologic comparison between 36 cases of early gastric cancer (EGC) and 34 cases of early cancriform progressive cancer (ECPC) were made. It was found that there was no difference in the average age and sex. Epigastric pain occurred in most of the cases. Weight loss, hematemesis and melena occurred more frequently in patients with ECPC than those with EGC. Pathologically, the cancers were located in gastric antrum in most of the cases in both groups. The lesions 1-2 cm across accounted for half in each. Lesions over 4 cm (19.4%) was obviously more common in EGC than in ECPC (2.9%). Macroscopic classification showed that though pouch-type predominated in both groups, it was more frequent in ECPC (88.2%) than in EGC (72.2%). Histologically, there were more highly differentiated types in EGC (52.7%) and more poorly differentiated types in ECPC (52.9%). The Pm depth of ECPC was high. The prognosis of ECPC was favorable, second only to EGC. ECPC belongs to Type 5.
