The effect of chalone-containing ethanol extract of rat skin (CCE) on the growth in mice of transplanted uterine cervix and skin carcinomas, hepatoma-22a, sarcoma-180 and leukemia L-1210 was studied. When CCE is added to the suspension of tumour cells (10 mg CCE/100 mg tumour tissue/ml saline) the most obvious retention of tumour growth is observed on squamous-cell carcinoma of uterine cervix (72.6%; p less than 0.01). The effect of CCE on the growth of other transplanted tumours, including the skin carcinoma, is not significant. As compared to the uterine cervix carcinoma, the skin carcinoma lacked its primary squamous-cell structure during the tumour progression. The possibility of applicative use of chalones for cancer control is discussed.

It is well known that there are many independent and inter-related clinical and pathologic factors which influence the prognosis of patients with benign and malignant conditions. Lymphocyte level is an index of cell-mediated immunity which is important in host defense against cancer. But it is surprising that a simple test such as peripheral lymphocyte count could be correlated with clinical stages and survival results in patients with Hodgkin's disease, non-Hodgkin's lymphoma and non-lymphomatous solid tumors. Regarding the latter, lymphocyte count had prognostic values in patients with cancer of the bone, Ewing's sarcoma; breast; colon; kidney, neuroblastoma; uterine cervix, and other sites. In general, higher lymphocyte counts before therapy correlated with longer survival. Using newer immunologic techniques, T and B lymphocytes can be identified and the different subtypes of leukemia, immunodeficiency and lymphoproliferative diseases have been studied intensively. Chronic lymphocytic leukemia represents a proliferation of B cells, while the Sezary syndrome represents that of T lymphocytes. There is a qualitative and quantitative disturbance of Blymphocytes in patients with multiple myeloma. In Hodgkin's disease, there is hyperactivity of the B cells and functional defect of the T cells. Finally, the nodular non-Hodgkin's lymphoma resulted from neoplastic transformation of the B lymphocytes. In several nonmalignant autoimmune conditions, abnormality of T-cell or B-cell counts has been reported. For example, T cells were reported to be decreased in patients with ulcerative or granulomatous colitis and in patients with rheumatoid arthritis, However, it needs to be pointed out that, in 1973, Farid and associates (44) reported a significant increase in T and a proportionate reduction of B rosette in 17 patients with untreated Grave's disease and 16 with Hashimoto's thyroiditis as compared with 24 normal and eight goiter controls. In 1975, six publications later, they (143) had to announce a retraction because further studies by them and by other investigators could not repeat the earlier results. Despite variations and lack of standardization of the test systems, some consistent deviations of T-lymphocyte and B-lymphocyte counts have been reported. T lymphocytes were quantitatively decreased in patients with carcinoma of the brain, breast, head and neck, liver, lung and urologic organs and with malignant melanoma. In general, there is a marked decrease of T cells with increasing stage of disease and a return of T cells to normal level after successful therapy. Cellular immunity is depressed, often lasting for years after localized radiation therapy, whether or not the thymus is included in the treatment field...

A case of granulocytic sarcoma involving the uterine cervix as primary manifestation without evidence of leukemia is presented. It was followed by neurological symptoms 19 months later and a right breast mass 26 months after the initial cervical lesion, but still with no evidence of leukemia. Two years and four months after onset, soft tissue and skin nodules developed and rare blastic cells appeared on peripheral blood smear. The patient terminally developed acute granulocytic leukemia with a rapidly downhill course. The differential diagnosis of granulocytic sarcoma and histiocytic lymphoma is discussed. The literature is reviewed with emphasis on the clinical and pathological problems that arise when the tumor presents in an unusual location without peripheral blood manifestation of leukemia.

We compared age-adjusted mortality rates for cancer of selected sites for Chinese, Japanese, and native Indian residents of British Columbia during the years 1964-73 to the corresponding rates for the white population. Mortality from all cancers of the Chinese did not differ significantly from that of whites. Elevated rates are seen for cancer of the nasopharynx in both sexes, of the liver and esophagus in males, and of the lung in females. Chinese males had a lower mortality than whites from stomach, prostate, and bladder cancer and brain tumors, whereas females had a lower mortality from tumors of the colon, breast, and ovary; both sexes had a lower mortality from leukemia. For Japanese males and females, the mortality rates for all cancers combined were similar to those of the white population. The rates for cancer of the stomach and gallbladder were higher in both sexes; males also showed a higher rate of liver cancer. Prostate and breast cancer mortality rates were lower. Native Indian males had a lower mortality rate from all cancers combined; the difference was significant for stomach, colon, lung, and prostate cancers, and for leukemia. Native Indian females showed a lower rate for ovarian cancer and a higher rate of tumors of the gallbladder and uterine cervix, but their overall cancer mortality was similar to that of whites.

Patterns, change in occurrence, causative risk factors, and control strategy for cancer of each site in Japanese populations were studied by applying standard methods and techniques of biostatistics and epidemiology. As the results, cancers in Japan were classified into two groups: one on the decrease (stomach, cervix) and the other on the increase (lung, colon, pancreas, breast, prostate, urinary organs, leukemia). Analysis of vital statistics, national nutrition survey data, and on-going prospective study data revealed change in selective dietary intake and increase in cigarette consumption are the major factors responsible for such trend. Epidemiological characteristics and major risk factors of cancers of stomach, colon, pancreas, lung, breast, uterine cervix, ovary, endometrium, prostate, urinary bladder, and leukemia in Japan were summarized. A limited effect of mass screening was observed in the case of stomach cancer in addition to the strong effect of diet and nutrition. Cigarette smoking was confirmed to be the major causative factor of lung cancer in Japan. A close association of increased intake of animal fat and breast cancer risk in Japanese women was also observed.

The published studies of cancer of United States Jews are reviewed. Despite the lack of religious designation on death certificates, case reports, and census returns, a number of indirect methods for measuring the problem have been devised, which produce fairly consistent findings. In general, for American Jews, these show deficits in cancer mortality, among males, for the buccal cavity and pharynx and prostate and, among females, for the breast, uterine cervix and corpus, and bladder. Excesses in mortality, noted for both sexes, are esophagus, stomach, colon, pancreas, lymphomas, and leukemia and, in females, the lung and the ovary. The standardized mortality ratios for cancer of selected sites for Russian-born residents of upstate New York, 1969 through 1971, are presented as an indirect measure of the problem in the United States Jews. Statistically significant excesses were found in males for stomach and colon, with a striking deficit in cancer of the buccal cavity and pharynx. Among females, excesses were noted for stomach, pancreas, and lung with a sharp deficit in the uterine cervix. On the basis of the religious affiliation of the cemetery of burial, estimates of the Jewish and non-Jewish components of the 800 deaths in Russian-born residents were determined. Expected deaths in these two subgroups by sex, for each cancer site, were then calculated by use of the site-specific proportionate mortality of upstate New York for these years. This revealed a significant excess among Jewish males for colon cancer, with a deficit in lung cancer, while among the non-Jewish male components stomach cancer mortality was the only site significantly in excess. Among Jewish females, stomach and lung cancers were in excess, with a deficit in cancers of the breast and cervix uteri. In non-Jewish Russian-born females, the only site significantly in excess was stomach, with breast cancer showing a deficit.

YK-176 is a newly isolated 2'-deoxycoformycin (DCF), a potent inhibitor of adenosine deaminase, produced by Aspergillus nidulans. In a cooperative phase I study, YK-176 was administered to 22 patients, comprising 18 with adult T-cell leukemia-lymphoma (ATL), two with cutaneous T-cell lymphoma (CTCL), one with lymphoblastic lymphoma of T-cell type and one with carcinoma of the uterine cervix. Doses of YK-176 ranged from 3.0 to 9.0 mg/m2 and were given intravenously for three consecutive days. General malaise, anorexia, nausea, vomiting and low grade fever were frequently encountered, but were transient and not dose-related. At all dose levels hematological toxicities were mild. Two of seven patients receiving 7.0 mg/m2 for three consecutive days developed hepatocellular enzyme elevations (grade 2) and one patient, proteinuria (grade 2). One of two patients given 9.0 mg/m2 for three consecutive days manifested a life-threatening (grade 4) disturbance of consciousness and dyspnea, presumably ascribable to the drug-related toxicity of YK-176. The results suggest that 7.0 mg/m2 i.v. for three consecutive days is the maximum acceptable dose of YK-176. Central nervous system, pulmonary and possibly renal toxicities appeared to be dose-limiting. Out of the 20 patients evaluable for therapeutic response, partial remissions were observed in four, three with ATL and one with CTCL, who received less than 7.0 mg/m2 for three consecutive days. We conclude that YK-176 is an active agent against ATL at doses that may not be associated with prohibitive toxicity. A starting dose of 5.0 mg/m2 for three consecutive days is recommended for further phase II studies on ATL.

Radiation-induced cancers after radiation therapy for cancer of the uterine cervix were investigated on 11,855 patients including 5725 patients treated with radiation therapy alone, 1969 postoperative radiation therapy and 4161 surgery alone. The observed-to-expected ratios of the second primary cancer was 0.933 for the patients with radiation therapy alone and 1.074 for the patients with postoperative radiation therapy, respectively. No significant increase was observed in the risk of second primary cancers when all sites were combined. However, assessing on site by site basis, significant excess was noted for the rectum cancer, leukemia, and bladder cancer for the radiation therapy group but not for the surgery group. A significant excess of lung cancer was observed in both radiation therapy and surgery groups, which was attributed to some other causative factors. Radiation-induced cancers were suggested to develop apparently in organs involved in the irradiated field.

Age-adjusted mortality rates were analyzed to examine the dose-response relation between ingested arsenic levels and risk of cancers and vascular diseases among residents in the endemic area of blackfoot disease, a unique peripheral vascular disease associated with long-term exposure to high-arsenic artesian well water and confined to the southwestern coast of Taiwan. The arsenic levels in well water determined in 1964-1966 were available in 42 villages of the study area, while mortality and population data during 1973-1986 were obtained from the local household registration offices and Taiwan Provincial Department of Health. Age-adjusted mortality rates from various cancers and vascular diseases by sex were calculated using the 1976 world population as the standard population. A significant dose-response relation was observed between arsenic levels in well water and cancers of the bladder, kidney, skin, and lung in both males and females, and cancers of the prostate and liver in males. However, there was no association for cancers of the nasopharynx, esophagus, stomach, colon, and uterine cervix, and for leukemia. Arsenic levels in well water were also associated with peripheral vascular diseases and cardiovascular diseases in a dose-response pattern, but not with cerebrovascular accidents. The dual effect of arsenic on carcinogenesis and arteriosclerosis and the interrelation between these two pathogenic mechanisms deserve more intensive study.

Between 1950 and 1984 out of 57.393 women who delivered at the First Department of Obstetrics and Gynecology, Catania University Medical School, Catania, Italy, 40 cases of malignant neoplasia were diagnosed with an incidence of one case in 1.434 deliveries. The most frequent neoplasias is cervix carcinoma (21 cases; 52.5%), followed by breast cancer (6 cases; 15%), ovarian cancer (4 cases; 10%) and leukemia (4 cases; 10%). There was very rare association with Hodgkin disease (2 cases; 5%), osteosarcoma (1 case; 2.5%), medulloblastoma (1 case; 2.5%), and skin melanoma (1 case; 2.5%). Since cancer of the uterine cervix is the most frequent neoplasia (one cases out of 2.733 deliveries), cervical smear should be performed during pregnancy in women that never performed it.
