Evaluation of a mass screening program for stomach cancer.

To evaluate a mass screening program for stomach cancer, we followed 32,789 subjects for 6.1 years by means of a record linkage to a population-based cancer registry. The results show that the mortality from stomach cancer among those studied decreased by 9% as compared with the expected number calculated on the basis of the sex- and age-specific rates among the general population. When the study subjects were limited to those aged 40-59 years, the decrease in stomach cancer deaths became more marked, i.e., a 26% decrease was observed. Because this study is not a controlled trial, the results must be interpreted with the reservation that some biases were present in the study subjects.

Descriptive epidemiology of cancer in Japan: current cancer incidence and survival data.

The Research Group for Population-Based Cancer Registration in Japan, which has been collecting cancer incidence and mortality data from participating registries annually since 1974, has also been estimating cancer incidence rates for the whole of Japan by sex, age, and site. Data from the third survey have now been analyzed. Marked changes have been observed by the Osaka Cancer Registry in incidence rates of some sites during this period. Five-year relative survival rates for registered cancer cases have been calculated by the Osaka Registry for the first time in Japan.

The value of epithelial membrane antigen in the diagnosis of ovarian tumors.

The value of epithelial membrane antigen (EMA) in the diagnosis of ovarian tumors was investigated using an indirect immunoperoxidase staining technique on 91 histologic sections (88 tumors and 3 normal tissues) and 39 ascitic fluid smears (28 from patients with epithelial ovarian tumors and 11 from cases of myoma uteri). The rate of positive EMA staining was highest in malignant tumors (89.2%), second highest in tumors of low malignant potential (33.3%) and lowest in benign tumors (25.0%); normal ovarian tissues were negative for EMA. Of the malignant tumors, all 48 serous cystadenocarcinomas (100%) and 18 of 26 mucinous cystadenocarcinomas (69.2%) stained positively for EMA. In serous cystadenocarcinomas, the EMA staining was mainly localized on the luminal membrane of cells in well-differentiated tumors, but appeared on the entire cell surface and cytoplasm of cells in poorly differentiated tumors. The results of EMA staining on ascitic fluid smears were almost the same as the results for the histologic sections. The intensity and the localization of EMA staining were related to the grade of malignancy in these ovarian tumors. In comparison with staining for other antigens (carcinoembryonic antigen, CA-125 and human keratin protein), EMA was found to be one of the most sensitive markers for the diagnosis of ovarian cancer.

Clinical and cytologic aspects of primary fallopian tube carcinoma. A report of ten cases.

The clinical and cytologic findings in ten cases of primary fallopian tube carcinoma, a very rare malignancy, are presented. All ten patients had vaginal pool (V), cervical (C), endocervical (E) and endometrial aspiration (EA) smears examined preoperatively; peritoneal smears were also prepared from cul-de-sac fluid aspirated during surgery. In the preoperative cytodiagnosis, some of V, C, E and EA smears were positive for malignant cells in six of the ten patients (60%). Examination of the EA smear was the most effective means of discovering this disease. A watery discharge was noted in two patients, both of whom were negative in the preoperative cytodiagnosis. In such patients, it is necessary to repeat the smear examinations. The cytologic appearance of this disease is contrasted to that of endometrial carcinoma.

Psammoma bodies found in cervicovaginal and/or endometrial smears.

Eight cases of the unusual occurrence of psammoma bodies associated with adenocarcinoma cells in cervicovaginal and/or endometrial smears are presented. Three of the eight cases were advanced ovarian cancers, four were primary endometrial adenocarcinomas, and one was a metastasis of breast cancer to the pouch of Douglas. From our histologic and histochemical observations, psammoma bodies seem to be secretory rather than degenerative in origin.
