Sera from 134 selected patients with various types of cancer were tested for soluble antigen-antibody complexes by the C1q binding method. Sera from 85 healthy blood bank donors served as normal controls. C1q binding activity (C1q BA) values above the 95th percentile for healthy subjects were found in 83% of sera from patients with neoplastic diseases. The incidence of abnormal C1q BA values among patients with malignant melanoma was 83%, with breast cancer 74%, with colon cancer 75%, with lung cancer 88%, with leukemia and lymphoma 85%, and with miscellaneous tumors 94%. High C1q BA values were found most frequently in sera of patients who had been diagnosed relatively recently (within 5 mo) and who had evident residual disease after surgical treatment. Recurrence or progression of tumor growth occurred significantly more frequently in lung cancer patients with high C1q BA. DNA was not detected in cancer patients' sera and treatment with DNase did not decrease in C1q BA. C1q BA in sera could not be explained by the presence of antiglobulin antibodies. Sucrose density gradient ultracentrifugation studies of the serum C1q BA in 4 cancer patients showed that the major binding activity was found between 19S and 7S.

The efficacy of trofosfamide (Ixoten; Noristan), a derivative of cyclophosphamide, was investigated in 76 patients. Those with solid tumours were given 50 mg/kg in 6 divided doses in 48 hours; those with chronic lymphatic leukaemia were treated with 100 mg orally 3 times a day for up to 10 weeks. Side-effects of treatment included leucopenia, thrombocytopenia, a fall in the haemoglobin level, haematuria and occasional alopecia. Nausea was never severe, and occurred in only half of the patients on a high dose and in none of the patients on a low dose. A therapeutic effect was observed in patients with breast cancer, cancer of unknown origin and pancreatic cancer. Twenty-one of 24 patients with chronic lymphatic leukaemia (all of whom had aggressive disease) responded to treatment, and complete remission (including normal bone marrow), was achieved in 5 of these patients.

The risk factors for radiation induced cancer (no dose threshold) given by UNSCEAR and ICRP are discussed. Under the (uncertain) supposition of the validity of these values for the roentgendiagnostic the number of cases induced by the mass screenings (VRRU) are estimated (lung and breast cancer, leukaemia). For 30 radiophotofluorographs of the thorax per person during the whole life there may be induced about 180 cancer of the lung, 5 of the breast and 27 leukaemias each year. These numbers are compared with the cases per year of lung tuberculosis and lung cancer found by VRRU. The connection between the cases of cancer and the irradiation cannot be validated statistically.

A characteristic alkaline phosphatase (orthophosphoric monoester hydrolase, alkaline pH optimum, EC 3.1.3.1) was detected in the sera of most patients with infectious mononucleosis, acute and chronic lymphatic leukaemia, non-Hodgkin's lymphoma, Burkitt's lymphoma and nasopharyngeal carcinoma. The enzyme was also present in the sera of nine out of 26 patients with cancer of the cervix. N-APase in these cases counted 30-100% of the total alkaline phosphatase activity. N-APase was absent from the sera of healthy individuals and of patients with acute and chronic granulocytic leukaemia, breast cancer, colon cancer, rheumatoid arthritis, ulcerative colitis, systemic lupus erythematosis, hepatitis and obstructive jaundice. Only three of 22 patients with Hodgkin's disease showed n-apase activity in the serum. In infectious mononucleosis the presence of N-APase activity was well correlated with the clinical course. In 13 cases studied, the clinical improvement was associated with the decrease or disappearance of N-APase activity. N-APase activity could not be detected in white cells of acute myeloid leukaemic patients, nor in the cells of myeloid blastic crisis of chronic granulocytic leukaemia. It was present in the cells of lymphoid blastic crisis of chronic granulocytic leukaemia.

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 incidence of malignancy among patients with Graves' disease who were residents of one Minnesota county was examined in 342 patients between 1935 and 1967. During 4,736 person-years of observation, 32 malignancies were diagnosed; 24 cases were expected and the difference is not significant. Four cases of breast carcinoma were found vs five expected. Other tumor sites were cervix (five), uterus (two), rectosigmoid colon (three), stomach (two), larynx (two), and lung (two). There were three cases of leukemia, and in nine other sites one cancer each was recorded. There was a slightly higher than expected incidence of malignancy in patients who had received 131I therapy; this finding requires further study in a larger patient population. Among patients who received thyroid hormone, the observed incidence of breast cancer was not significantly different from the expected incidence in our population.

A rigorous, comprehensive, and reliable reversed-phase high-performance liquid chromatographic (HPLC) method has been developed for the analysis of ribonucleosides in urine (psi, m1A, m1I, m2G, A, m2(2)G). An initial isolation of ribonucleosides with an affinity gel containing an immobilized phenylboronic acid was used to improve selectivity and sensitivity. Response for all nucleosides was linear from 0.1 to 50 nmoles injected and good quantitation was obtained for 25 microliter or less of sample placed on the HPLC column. Excellent precision of analysis for urinary nucleosides was achieved on matrix dependent and independent samples, and the high resolution of the reversed-phase column allowed the complete separation of 9 nucleosides from other unidentified UV absorbing components at the 1-ng level. Supporting experimental data are presented on precision, recovery, chromatographic methods, minimum detection limit, retention time, relative molar response, sample clean-up, stability of nucleosides, boronate gel capacity, and application to analysis of urine from patients with leukemia and breast cancer. This method is now being used routinely for the determination of the concentration and ratios of nucleosides in urine from patients with different types of cancer and in chemotherapy response studies.

The cause-specific mortality of women with cancer of the breast or of the intestines (= small intestine and colon) diagnosed in 1953-70 in Finland was analyzed with respect to the extent of the disease, the age of the patient at the time of diagnosis, and the follow-up time. The total mortality in breast-cancer patients was higher than had been expected during the entire follow-up period (maximum of 18 years), whereas in patients with intestinal cancer no more than slight excess mortality existed after 5 years of follow-up. The mortality from cardiovascular diseases was less than had been expected among patients with intestinal cancer. Patients with non-localized cancer of the breast had a risk of dying from accidents and other violent causes of death during the first 5 years of follow-up which was slightly higher than expected. From information compiled from various sources, the Finnish Cancer Registry records not only the official cause of death mentioned on the death certificate, but also a "corrected" cause of death. With this correction, the mortality from forms of malignancy other than the primary cancer was lower than had been expected during the first 5 years of follow-up, and subsequently reached the level expected. In regard to specific sites, mortality lower than that expected was observed for cancer of the stomach (both breast- and intestinal-cancer patients), and cancer of the cervix uteri (breast-cancer patients). In patients with localized breast cancer, the mortality from leukaemia was higher than that expected after 5 years of follow-up. No mutual excess risk was demonstrable with breast and intestinal cancers.

From the Third National Cancer Survey (TNCS) Interview Study of 7,518 incident cases, lifetime histories of occupations and industries were studied for associations with specific cancer sites and types while controlling for age, sex, race, education, use of cigarettes or alcohol, and geographic location. Lung cancer patients were found more often than expected among several categories including trucking, air transportation, wholesaling, painting, building construction, building maintenance, and manufacturing (furniture, transportation equipment, and food products). Controlling for cigarette smoking did not change these associations. Leukemia and multiple myeloma were associated with sales personnel of both sexes, whereas lymphomas and Hodgkin's disease were excessive among women working in the medical industry. Other associations included rectal cancer with several retail industries; prostate cancer with ministers, farmers, plumbers, and coal miners; malignant melanoma with school teachers; and invasive cervical cancer with women working in hotels and restaurants. Breast cancer patients were more common among women who were teachers or other professionals and who worked in business and finance (even after controlling for education). Many other findings are presented in detailed tables. Results are reported mainly as a research resource for use by other investigators doing work in this field. Suggestions are given for future studies.
