| Abstrakt: | A histological mapping procedure was used to study 32 stomachs bearing small cancers and 23 stomachs bearing ulcers. Over 80 per cent of gastric cancers and peptic ulcers occurred within 2 cm of both a mucosal junction and the lesser curvature. They showed slight differences in their longitudinal relationship to the pyloric junction. There were differential characteristics between the groups of cancers arising at each of the three mucosal junctions. Cancers at the pylorus and cardia were more common in males (M:F--2.6:1) and were predominantly well differentiated, whereas those from the intermediate zone were more common in females (M:F--1:1.8) with a relatively higher proportion of undifferentiated cancers. These and other features suggest that gastric cancers should be subdivided according to the junction of origin. |
