  • Abstract
  • Look Inside

 Two hundred and thirteen adenomas in 177 patients were examined with respect to the clinicopathological aspects and the significance as precancerous lesions. The results and our conclusions are summarized as follows:

 1) Adenomas were most frequently seen in the resected specimen of early gastric cancer.

 2) Most of the cases were the elderly with the highest frequency in the seventh decade. Male to female ratio was 3.2: 1 in overall, but was nearly equal at 1.3: 1 among cases of pure and simple adenoma.

 3) Most of the lesions were located in either M or A regions, whereas those in the C region were rarely seen.

 4) Most of the lesions were an elevated type (78.4 %) with Ⅱa-like elevations being particularly most frequent (68.1%).

 5) Most (83.6%) of the lesions were small, less than 2 cm in diameter.

 6) Focal cancer in adenoma, which is thought to be the result of malignant change of adenoma, was found in at least 5 lesions (3.5%). Adenoma concomitant with carcinoma within the same lesion was seen in 23.4% of 230 adenomas.

 From the macroscopic point of view, the main factors of high cancer coincidence rate were the size larger than 2 cm and configuration of Is or depressed type. From the histological point of view, the factors are papillary features, grade Ⅲ atypia and the so-called “gastric-type” adenoma.
