Urinary steroid hormone content was determined in Black and White North American men and in rural Black South African men between 40 and 55 years of age and in Black South African men over 60 years of age when maintained on their customary diets or when transferred to a vegetarian or Western diet, respectively. When eating their customary diets, Black South African men had lower levels of urinary estrogens and androgens than did Black and White North American men. The total androgen content decreased significantly in Black North American men on the vegetarian diet and increased in Black South African men fed a Western diet. Urinary excretion of estrogens was higher in older than in younger rural Black South African men. Data indicated that a vegetarian diet modified androgen and estrogen metabolism in North American men and that a Western diet was associated with higher levels of urinary steroid hormones in young Black South African men. Diet-related changes in steroid metabolism in rural Black South African men were age dependent. The relationship of the increased urinary excretion of steroid hormones in Black South African men, a low-risk group fed a Western diet, and the decreased excretion in Black and White North American men, high-risk groups fed a vegetarian diet, to the development of prostatic cancer remains to be clarified.

One hundred and forty-seven fully and partially evaluable patients with advanced measurable malignancies of the genitourinary and gynecologic organs were given cis-dichlorodiammineplatinum(II) at a dose of 75 mg/m2 iv every 3 weeks. Thirty-six patients with testicular neoplasms were studied; five complete responses (13.9%) and seven partial responses (PR) (19.4%) were noted. Thirty-seven patients with ovarian adenocarcinoma were evaluated; five PRs (13.5%) were seen. One complete response (11.1%) and two PRs (22.2%) were obtained among nine patients with urinary bladder cancer. Four PRs (19.0%) were seen among a group of 21 patients with advanced prostate cancer. One PR (4.8%) was noted among 21 patients with renal cell cancer and no responses were seen in eight patients with cervical cancer. There was a highly statistically significant (P less than 0.001) survival advantage for the responding testicular tumor patients. Toxicity was similar to that previously reported, with gastrointestinal side effects and nephrotoxicity most commonly seen. Prospective and sequential analysis of renal function provided strong evidence for cumulative nephrotoxicity in these patients given bolus injections of cis-dichlorodiammineplatinum(II) without prehydration or treatment with fuosemide or mannitol.

A prospective epidemiologic study of prostate cancer was conducted in Japan. The 10-year follow-up study of 122,261 men aged 40 years and above, who constitute 94.5% of the census population of 29 Health Center Districts, revealed a significantly lower age-standardized death rate for prostate cancer in men who daily ate green and yellow vegetables. This association is consistently observed in each age-group, in each socioeconomic class, and in each prefecture. Selected epidemiologic phenomena, such as the upward trend of the prostate cancer death rate in Japan, intracountry variation of death rate, the significantly lower incidence rate in Japan compared with that of the United States, and elevated risk in Japanese migrants to Hawaii, appear to be explained by the variation in diet and change in amount of green and yellow vegetables ingested. The possible role of vitamin A is considered as a factor in preventing and inhibiting growth of prostate cancer. Most of the other factors studied appear noncontributory, except for marital status; a higher risk was observed in "ever married" men.

Human prostate cancer has been successfully transplanted into nude mice, and our technique is briefly reviewed. Sections of human benign prostatic hypertrophy have also been successfully transplanted, with subsequent cellular multiplication. This technique provides a promising model for laboratory studies of therapy by hormone manipulation.

The Japanese-American population was particularly well suited for the study of cancer occurrence because: 1) An American-born population as well as the immigrant Japanese-American population could be studied; 2) good cancer incidence and mortality data from Japan could be compared with data from the United States; and 3) some differences in the rate of occurrence of several specific cancer sites in Japan as compared with the United States were striking. The most significant of these involved the gastrointestinal tract and sex organs. Data were presented concerning cancer incidence rates for the Japanese-American population of the San Francisco Bay area. The high gastric rates for the Japanese in Japan were reduced in a stepwise fashion in the immigrant Japanese-American population to the American-born Japanese who were approaching the low rate of the United States. Colon cancer rates, which were low in Japan, approached the rates in the United States in both the immigrants from Japan and in Japanese Americans. The low rates of cancers of the breast, uterine corpus, and ovary of Japanese women in Japan and for prostate cancer among men rapidly approached the higher rates for these cancer sites that existed in the United States. A study of nutritional factors related to the increase of cancer of the breast in Japanese Americans is being conducted.

Bone marrow acid phosphatase has been reported to be a sensitive indicator of early bony metastasis from adenocarcinoma of the prostate. In order to evaluate this hypothesis, we measured bone marrow acid and alkaline phosphatase, lactic dehydrogenase, and calcium levels in a group of 84 patients with a variety of problems, including 18 with cancer of the prostate. We found that the bone marrow acid and alkaline phosphatase and lactic dehydrogenase were elevated and calcium was depressed in most patients. Among patients with prostate cancer, bone marrow acid phosphatase was not significantly different between those with or without bone metastases. In addition, the patients with prostatic cancer did not have higher levels of bone marrow acid phosphatase than subjects with other malignant and nonmalignant conditions. The level of acid and alkaline phosphatase, lactic dehydrogenase and calcium varied predictably with the aspiration technique used and was independent of sex, disease state or method of chemical determination. Due to this variation, we believe that bone marrow enzyme and calcium levels are of no value in the detection of metastases in patients with prostate cancer.

Among the most striking epidemiologic characteristics of prostatic cancer in the United States is the sizeable excess in rates for the disease among blacks as compared with whites. This study attempted to determine whether the higher black rates might be explained by controlling for social class, using mortality data from Alameda County for the pericensal period 1968--1972 (n = 400), and the population-based series of cases for Alameda County included in the Third National Cancer Survey, 1969--1971 (n = 750). Reviewed first are previous studies addressed to the relationship of prostatic cancer and socioeconomic status (SES), most of which have been confined to whites. In the present study, each death or case was assigned to a socioeconomic class based on census tract of residence and rates by race and social class determined. Comparison of age-specific mortality and incidence rates by SES reveals no gradient for prostatic cancer in either whites or blacks.

In recent decades, age-adjusted mortality rates from prostatic cancer have risen precipitously among blacks, remaining unchanged among whites. It is now the most common cancer among United States black males. When nonwhite mortality rates were examined by age and birth cohort, it was found that peak rates occurred at every age in the cohort of 1896 to 1900, and declined thereafter. This presages an arrest and reversal of the time trend in summary mortality rates as more recent nonwhite cohorts reach the ages of maximum risk.

The recording of new cases of cancer in the Bas-Rhin department interest about 883 000 persons in 1975. 3 073 cancer cases have been registered. The data show an incidence of 424 per 100 000 for male population and 309 per 100 000 among female population. Among male population: lung cancer is the most frequent, it represents 17.1 per cent of male cancers with an incidence of 72.5. In second position cancer of the rectum and recto-sigmoid which represents 7.9 per cent of cancers; it has an incidence of 33.4 per cent. Then followed in this order: prostate cancer with an incidence of 32.3, colon cancer with an incidence of 30.1, cancer of the stomach, and bladder. Among female population: breast cancer is by far the most frequent, it represents 27.5 per cent of all cancers, the incidence is 88.4; next corpus uteri cancer with an incidence of 29.5; colon cancer with an incidence of 25.4, followed by cervix uteri cancer with an incidence of 22.1. The genital localizations, on the whole represent 23.2 per cent of cancers with an incidence of 75.3. It is too early to interprete the recorded disparities among the different districts, nevertheless, one can think that the low rates reported in some districts is due to an under-recording.

Three cases of metastatic adenocarcinoma of the male breast from prostatic carcinoma are added to the 15 well-documented cases reported in the literature. These 15 cases had received estrogen therapy for prostatic cancer and gynecomastia developed; 14 had clinically palpable breast nodules containing adenocarcinoma. Our 3 cases also received estrogen therapy but differed in that gynecomastia developed in only 1 patient clinically, and diagnoses were made at autopsy with no clinical symptoms related to breast metastases. Moreover, 1 cases also showed remarkable florid lactation-like changes of the breast almost indistinguishable morphologically from that seen in the female breast during pregnancy. The histopathologic differential diagnosis of metastatic prostatic carcinoma of the breast from primary cancer of the male breast is stressed. Its importance is obvious because of the differences in clinical treatment and prognosis. Microscopically, the differential points consist of duct hypertrophy and periductal fibrosis (gynecomastia), absence of any ductal involvement by carcinoma cells, frequent presence of cancer cells in lymphatics and vascular channels, morphologic similarity between the cancers in the breast and prostate, and finally, the usual presence of acid phosphatase in the tumors of the prostate and breast.
