[Critical study on dead cases in recurrent early stomach cancer (author's transl)].

35 deaths of 299 operated early stomach cancers have been studied retrospectively. These cases can be grouped in the following categories: 2 deaths directly due to operation, 7 due to recurrence of carcinoma, 19 due to other diseases including cancer in other sites and 7 cases in which the real causes of death could not be elucidated. Special attention was paid on the 7 recurrent cases: In 4 of 7 patients the histological study revealed lymph and blood vessels invasion in their resected stomachs, lymphnodes metastases in 5 patients and positive cut-end in 2 patients. 5 of 7 patients died within 3 years after operation.

[Imaging of the bronchial blood flow usingg RI-angiography--study on its procedure and application of dual radioisotope technique (author's transl)].

RI-angiography with 99mTcO4- was carried out using a scintillation camera with a digital minicomputer for the purpose of imaging of bronchial blood flow in various lung diseases, and as application of dual radioisotope techniques, other imagings such as tumor imaging with 197HgCl2 or 67Ga-citrate and/or perfusion imaging with 99mTc-MAA, were performed simultaneously in patients remaining the same position, too. The image as a iso-count map extracted out of the image of 197HgCl2, 67Ga-citrate or 99mTc-MAA, was superimposed to the brightness image of RI-anigogram (aortic phase). By these procedures, the image of bronchial blood flow were obtained in some patients with lung cancer, pulmonary tuberculosis, lung abscess, and chronic bronchitis. The dual radioisotope techniques using RI-angiography and the other imaging were useful to make isotope diagnosis of lung diseases more reliable, and the image superimposition methods using RI-angiogram and the image of tumor or perfusion, were useful to improve anatomic orientation of the former.

[Myocardial imaging with thallium-201--subtraction imaging with 201TlCl and 99mTcO4- for the visualization of the right ventricle--(author's transl)].

The dual radioisotope techniques with 201TlCl and 99mTcO4- were performed in 30 cases inclusive of various heart and lung diseases, using a scintillation camera coupling to a small digital computer. The scintigraphic procedures were started about 5 minutes after intravenous injection of 201TlCl. The myocardial images such as anterior, 60 degrees left anterior oblique, and left lateral view, were obtained. Next, 30 degrees left anterior oblique view was taken and radionuclide angiogram with 99mTcO4- was done in the same position too. This joint use of the myocardial imaging and radionuclide angiography could increase diagnostic reliability. Superimposing the image as iso-count map extracted out of radionuclide angiogram to the brightness image of 201TlCl, the anatomic orientation of the image of 201TlCl was improved. Subtracting the blood pool image with 99mTcO4- or radionuclide angiogram, which showed visualization of the right ventricle, lungs and left ventricle, from the image of 201TlCl, the subtraction image was obtained. The right ventricle was visualized more clearly on this subtraction image than the original image of 201TlCl. Good visualization of the right ventricle was shown in 25 cases on the subtraction image, and in 17 cases on the original image of 201TlCl.

[Statistical analysis of 1186 cases of gastric carcinoma: with special reference to advanced lesion (author's transl)].

750 cases of advanced gastric carcinoma were macroscopically and microscopically studied in relation with the 10 year survival rate. Most of the patients, 59.3% in female and 68.8% in male, belonged to the 5th and 6th decades. Macroscopically 44.1% of the cases were grouped in Borrmann III type, and secondly Early-Cancer Like Lesion, 26,6%. Histologically, in 510 cases out of 750 (68.0%) serosa was definitely broken by carcinoma cell nests and in 500 cases (66.7%) lymphnode metastasis was observed. The most frequent histological type was diffuse type, 44.9%, and secondly papillotubular type, 21.2%. 10 year survival rate of 516 cases, in which no residual cancer tissue was ascertained and the favorite prognosis could be expected was studied on various factors: Early-Cancer-Like-Lesion and Borrmann I & II types carcinoma, those cases in which the muscularis propria or serosa was preserved, those cases without lymphnode metastasis, and papillotubular or medullary tubular carcinomas showed a favorite prognosis in comparison with other types.
