In this study, I performed a clinicopathological study of the multiple early gastric cancers using their extent of the surrounding mucosal atrophy.
These 44 cases were classified into 4 types according to their surrounding mucosal atrophy ; the atrophic type in which all cancerous lesions were included in the atrophic zone, the intermediate type in which all lesions were in the intermediate zone, the atrophic-intermediate type in which each lesion was located in both atrophic and intermediate zones, and the last type in which one lesion was in the fundic gland zone.
The results were as follows :
1. All lesions of the multiple early gastric carcinoma were located in the atrophic or intermediate zone.
2. The frequency of each type was 20 cases (45%) for the atrophic type, 15 cases (34%) for the intermediate type, and 9 cases (21%) for the atrophic-intermediate type. Consequently, 80% of cancerous lesions were located in the same surrounding mucosa.
3. Each lesion in the atrophic type and the interm diate type was similar in the gross appearance, the histological type, and the extent of surrounding mucosal intestinal metaplasia. On the other hand, each lesion in the atrophic-intermediate type showed different features.
The conclusion is that most of the multiple gastric carcinomas come from the gastric mucosa in the same zone.
