Two-dimensional echocardiography was used to study malignant metastatic neoplasms of the heart and great vessels in 20 patients, 13 males and seven females, whose ages ranged from 15 to 72 years. Five patients had lung cancer; two each had breast cancer, malignant melanoma, hepatoma and one each had gastric cancer, urinary bladder cancer, adrenocortical carcinoma, malignant lymphoma, angiosarcoma, fibrosarcoma, leiomyosarcoma; and two had cancers with unknown primaries. Tumor invasion was demonstrated echocardiographically in the left atrium in one each with breast cancer, fibrosarcoma and gastric cancer; in the right atrium in two with hepatomas; in the right atrium and right ventricle in one patient with adrenocortical carcinoma; in the left ventricle in one with lung cancer; and in the pulmonary artery in one with malignant melanoma. Massive pericardial effusion was observed in 11 of 20 patients; two with pericardial tumors including malignant lymphoma and lung cancer. We conjectured that metastatic tumors in the right cardiac cavities came through the inferior vena cava, and other tumors in the left atrium, left ventricle and pericardium developed from direct extension of the primary lesions. There was an 80% mortality of the patients during the observation period, and the average survival period after the diagnosis of cardiac metastases was 5.5 months. However, one patient was still living after two years of radiation therapy and chemotherapy. Echocardiography proved a useful, non-invasive means for the detection and follow-up observation of metastatic cardiac tumors.

The 1970-census populations have been followed up for deaths and emigrations in the ten-year period 1970-80 in all the Nordic countries. The data show more than a 2-fold difference in overall mortality between the low-risk group of men with pedagogical work and the high-risk group of deck and engine crew workers. These data files have also been supplemented with cancer register records. In Denmark this combined data set has been used in four different ways. First, in order to check the validity of the register, classic associations known from in-depth epidemiological studies were tabulated. Examples are cancer of the lip in farmers and fishermen, where the standardized incidence ratio (SIR) values were 1.85 and 3.17, respectively, and cancer of the nasal cavities and sinuses in skilled furniture makers, SIR = 12.25. Second, a social cancer map was produced by tabulating the cancer incidence by 20 socioeconomic groups. The social gradient was steepest for certain rare cancers related to specific etiologic factors. The social gradient also varied across cancer sites. Third, the register was used as a library for elucidation of newly reported associations. An association confirmed in the Danish data is an excess risk of bladder cancer in hairdressers, SIR = 2.05. An unconfirmed example is an excess risk of malignant melanoma in the printing industry, where Danish data show an SIR of 0.95. Fourth, a systematic tabulation of each cancer diagnosis across detailed occupational groups may lead to identification of previously unknown associations. This procedure is illustrated using cancer of the larynx as an example. Smiths, mechanics, foremen, and shop owners of engineering works and workshops all have an excess risk of laryngeal cancer, SIR = 1.63.

The European Community (EC) mounted the "Europe Against Cancer" programme in 1987 to control cancer. Information on mortality rates is available for all member countries and the incident number of cancers was estimated for each site, for each country and for the EC as a whole. In 1980 there were 730,000 deaths from cancer and an estimated 1,222,120 [corrected] new cases (excluding non-melanoma skin cancers). Among men, cancer of the lung is the leading cancer site with some 135,000 cases per year followed by prostate, colon and bladder cancer. Breast cancer is the leading site in women, with 135,000 cases per year, followed by colon, stomach and genital cancer. Among men, melanoma of the skin, and lung, pancreas and rectum cancer are more frequent in the north in contrast to larynx, oesophagus, buccal cavity and liver cancer, which are more frequent in the south. There are additional contrasts between Southern European countries. The contrasts are less striking for women. This study provides an estimate of the true number of cases only. The establishment of a network of European cancer registries should eventually lead to more comprehensive incidence information form the EC.

In a study of 6,389 male cancer patients diagnosed and treated at the Cancer Control Agency of British Columbia from 1950-1975, several associations were detected between occupation and specific cancers. Elevated risks for lung cancer were seen in miners, metal processors and machinists, while a reduced risk was seen in farmers. Lip cancer excesses were detected in individuals involved in several outdoor occupations, and melanoma excesses were seen for three groups of predominantly indoor workers. These results confirm previous findings in the literature, whereas the following associations have not been previously reported. Fishermen were found to have an excess of Hodgkin's Disease (RR = 3.0, 95% C.I. = 1.4,6.5), engineers are at an elevated risk of cancer of the pancreas (RR = 4.2, C.I. = 1.8,9.9), and forestry workers have an elevated risk of bladder cancer (RR = 1.7, C.I. = 1.1,2.6). Further studies will be needed to replicate the new associations detected here.

The incidence of cancer in migrants to New South Wales (NSW) from Italy, Greece, Yugoslavia, Germany, the Netherlands, Poland and USSR has been compared with that in the Australian-born population using data from the NSW Central Cancer Registry for 1972-84. The indirectly age-standardized incidence ratios (SIR) in all seven countries were low for melanoma of skin and high for gastric cancer. Cancers of the colon, oesophagus and lip also tended to have low SIRs. Migrants from Italy, Greece and Yugoslavia had significantly less cancer at all sites than the native-born Australians mainly due to low SIRs for cancers of colon, lung (except Yugoslavian-born men), prostate and, in men, 'head and neck' (excluding nasopharynx). Cancers of breast and testis were relatively less common in migrants from Italy and Yugoslavia. SIRs were high for cancers of bladder (in Italian-born men), liver (in Greek- and Yugoslavian-born men) and nasopharynx (in Greek-born men and Italian-born men and women). Amongst migrants from the four more northerly European countries, ovarian cancer was relatively more common in women from Germany and Poland as was bladder cancer in men, but not women, from Germany and the Netherlands. Cancers which had significantly increased SIRs in one migrant group only were lung (Dutch-born men), cervix uteri and body of uterus (German-born women), gallbladder and bile ducts (Polish-born women), thyroid (Italian-born women), connective and other soft tissue (Russian-born men) and brain (Greek-born men and women computed together). Lymphomas were relatively less common in men born in Yugoslavia.

The aporphine alkaloids, dicentrine, glaucine, corydine, and apomorphine were shown to have inhibitory activity against several mouse tumor cell lines, leukemia P388 and L1210, melanoma B16, bladder cancer MBC2, and colon cancer Colon 26 in culture. These aporphine alkaloids also inhibited the mitogen-induced lymphocyte proliferation as well as the growth of IL-2 dependent CTLL2 line in a dose-dependent way. Of the four alkaloids apomorphine proved to be most potent in the inhibitory action. Apomorphine treatment resulted in some prolongation of survival time of the mice inoculated i.p. with P388, although its activity was not enough to meet the standard criterion for antitumor activity.

Previous investigations of cancer among firefighters have been limited to mortality data and have yielded inconsistent results. Case-control analyses were conducted in the present surveillance study in order to examine associations between firefighting and cancer incidence in Massachusetts. Subjects were identified through the Massachusetts Cancer Registry files for 1982-1986. Exposure status (firefighting) was determined from the usual occupation reported to the Registry. Nine different cancer types were examined among the 315 reported white male firefighters. Two "unexposed" reference populations were used: policemen and statewide males. Standardized morbidity odds ratios (SMORs) were statistically significantly elevated for melanoma (SMOR = 292; 95% C.I. = 170-503) and bladder cancer (SMOR = 159; 95% C.I. = 102-250) among firefighters compared with the state as a whole. When policemen were used as the reference group, the bladder cancer excess persisted (SMOR = 211; 95% C.I. = 107-414) and non-Hodgkin's lymphoma was elevated (SMOR = 327; 95% C.I. = 119-898); the melanoma excess was largely reduced (SMOR = 138; 95% C.I. = 60-319) but remained elevated among those aged 55-74 years (SMOR = 513; 95% C.I. = 150-1,750). Small number excesses (not significant) were also observed for pancreatic cancer and leukemia compared with police.

Cancer incidence in migrants to New South Wales (NSW) from the British Isles, north-central, eastern and southern Europe, the Middle East and Asia has been compared with that in Australian-born residents using data from the NSW Central Cancer Registry for 1972-84. Indirectly standardized incidence ratios (SIRs) were low in migrants from all 6 regions for melanoma of skin and cancers of lip and, except in men from eastern Europe, colon. Oesophageal, rectal and prostatic cancers also tended to be relatively less common. Cancers which were more common than in the Australian-born were those of the stomach and, for men, bladder (except in the Asian-born). Migrants from different regions showed variations from the cancer pattern of the Australian-born population which, for the most part, were predictable from the known incidence of cancer in the countries within the region of origin. Exceptions were the high relative incidence of nasopharyngeal cancer in migrants from southern Europe and bladder cancer in men from all regions other than Asia.

In the past decade, interferon, the first of a new class of biologic response modifiers, has undergone extensive Phase I and II clinical evaluation in a broad spectrum of cancers, including hematologic malignancies, lymphomas, and solid tumors. Interferon has been found to have important clinical activity in hairy-cell leukemia, low-grade non-Hodgkin's lymphoma, cutaneous T cell lymphoma, chronic myelogenous leukemia, previously untreated multiple myeloma, acquired immunodeficiency syndrome-related Kaposi's sarcoma, malignant carcinoid tumors, intravesically treated superficial bladder cancer, intraperitoneally treated ovarian carcinoma, renal cell carcinoma, and malignant melanoma. Recombinant DNA technology has produced molecules such as the interferons, which are antigenic and can induce antibody formation as part of a generalized immune response. The frequency of antibody occurrence, the magnitude of the antibody response, and the type of antibody induced by the interferons is thought to be related to several factors. These include the specific type of neoplasm for which interferon was administered; the specie of interferon administered; the dose, route, schedule, and duration of interferon administered; and the assay method and sampling time used to determine the antibody titer. Opinions and clinical observations about how these antibodies affect the clinical course of a disease vary among investigators. Some studies have demonstrated that antibody formation is associated with an abrogation of the clinical response, while others have not found any effects on the clinical course of a disease due to antibody presence.

A potential activity of interferons in the treatment of solid tumors has been suggested by in vitro experiments and, more recently, by phase I trials. Phase II trials have demonstrated a possible antitumoral activity in treating some solid tumors: malignant melanoma, renal cell carcinoma, ovarian adenocarcinoma, carcinoid tumor, superficial bladder cancer. Further trials are necessary to establish the precise role of interferons in treating solid tumors, when administered alone or in combination.
