[A comparative study between radiologic and macroscopic findings of small cancers less than 1 cm in the antrum of the stomach (author's transl)].
A comparative study was made of macroscopic and radiologic findings about 95 lesions (83 cases)  of small cancers (10 mm and below) in the antrum of the stomach, and the following results were obtained. 1) Preoperative diagnostic rate was 11/66 (17%) for lesions of micro-gastric cancers (5 mm and below), and 21/29 (72%) for lesions of small gastric cancers 5.1-10). Lesions of microgastric cancers which were preoperatively diagnosed as such were those with size of 3 to 5 mm accompanied by marginal elevations. 2) Radiologic findings about micro-gastric cancers. Some of the micro-gastric cancers which gave some findings in barium filled pictures existing along the greater or lesser curvature were observed as pictures of slight depression. In the compression pictures were noticed niches of irregular linear or stellar shapes with surrounding translucency. For qualitative diagnosis, the compression method was found most effective. It is considered very important to look for small niches, slight translucency, and slight deformity in the greater or lesser curvature carefully.
