    The nuclear DNA content in 71 cases of periampullary cancer (27, cancer of the head of the pancreas (Ph); 24, cancer of the ampulla of Vater (A) ; and 20, cancer of the inferior common bile duct (Bi)) was measured cytofluorometrically using the archival paraffin-embedded specimens of the primary lesions. They were analyzed in relation to prognosis, tumor size, histological differentiation, lymph node metastasis, lymphatic invasion, venous invasion, perineural invasion, and growth pattern. The results show that “Ph” has more unfavorable prognosis compared with the other two and it has more DNA content under the same conditions such as tumor from 2.1 to 4 cm in its greatest dimension, well differentiated adenocarcinoma, with or without lymph node metastasis, with or without venous invasion, with lymphatic invasion, with perineural invasion, and in the intermediate growth pattern between expansive and infiltrative. In conclusion, this study demonstrates a close correlation between the DNA content and prognosis and the significant clinical value of DNA analysis for predicting the prognosis in patients of periampullary cancer.

    Clinical data on 50 patients with arteriosclerosis obliterans (ASO) in China (Group A) and Japan (Group B) respectively were studied for better understanding of these changing trends. The results showed that the incidence of ASO peaked in Group A in the 50 to 69 age range (88%) and in Group B in the 55 to 74 age range (78%). Group A had a lower ratio of smokers and cases of diabetes mellitus than Group B but a higher ratio of hypertension and a higher total cholesterol level. Angiography showed that the prevalence of atherosclerotic lesions in the lower extremities as a whole was similar for both groups. They were different in location, extent and severity of the arteries involved between the two groups. We believe that this study has shown various differences between the two groups but that the causes are probably multifactorial.

    Squamous cell carcinoma (SCC) antigen is a tumor-associated antigen isolated from the squamous cell carcinoma of the uterine cervix. In order to estimate the usefulness of the SCC antigen in monitoring the clinical behaviors of oral squamous cell carcinomas, we analyzed clinicopathologically and immunohistochemically 54 cases of squamous cell carcinoma of the oral cavity. Elevated serum SCC antigen levels were detected in 23 (42.6%) out of 54 oral squamous cell carcinomas. The positive rate of serum sec antigen levels was significantly higher in the patients with advanced clinical stages and poorly differentiated carcinoma. The serum levels declined rapidly after the surgical operation. It is considered that the serum SCC antigen levels could be useful in monitoring the extension, effectiveness of therapy, recurrence and metastases of the oral squamous cell carcinomas. Immunohistochemically, strong staining was seen in the cytoplasm of the well differentiated carcinoma cells.
