Cancer incidence was studied among 6,144 male foundry workers who were invited to participate in either of two Danish national silicosis surveys conducted during 1967-1969 and 1972-1974. Cancer incidence was followed through to the end of 1985 by computerized linkage to the Danish Cancer Registry, and Standardized Morbidity Ratios (SMRs) were calculated based on incidence rates for the Danish population. For the entire cohort, significantly elevated SMRs were seen for all cancers (SMR, 1.09; 95% CI, 1.01-1.18) and lung cancer (SMR, 1.30; 95% CI, 1.12-1.51), and SMRs were at the borderline of statistical significance for bladder cancer (SMR, 1.24; 95% CI, 0.97-1.59). Excess lung and bladder cancer risk were confined to workers who had worked in foundries for at least 20 y. There was a positive correlation between silicosis prevalence in employees at the foundries at the time of the x-ray examinations and lung cancer incidence during the follow-up period. Squamous cell carcinomas, anaplastic carcinomas, and other lung cancers accounted for the excess lung cancer risk, whereas there was not excess risk among the foundry workers for adenocarcinomas of the lung.

Epidemiology of cancer was studied in a group of aniline-dye industry workers. Cancer morbidity in those directly exposed to betanaphthylamine and benzidine was 1.8 and 2 times the expected one for males and females, respectively (p less than 0.05). Bladder cancer morbidity was many times the expected one for both males and females; it did not involve prevalence in male morbidity generally observed for this site. Primary multiple malignant tumors were more frequently registered in females. Stomach and lung cancer morbidity was increased in males (p less than 0.05). Also, prophylactic measures should be taken at factories using amino compounds which are suspected to be carcinogenic for man.

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.

To study the effect of the environments shared by spouses on the development of cancer and some chronic diseases, we analyzed the correspondence of disease history in 21,592 fathers and mothers using the baseline data of a population-based cohort study. The observed number of cases (O) whose parents had the same disease history was statistically significantly greater than the expected (E); the O/E ratio was 1.53 (95% confidence interval (CI): 1.43-1.63) for all malignant neoplasms, 5.22 (95% CI: 2.81-9.70) for esophageal cancer, 1.63 (95% CI: 1.37-1.93) for stomach cancer, 3.01 (95% CI: 1.89-4.79) for colorectal cancer, 3.90 (95% CI: 2.75-5.53) for liver cancer, 3.14 (95% CI: 1.95-5.08) for lung cancer, 6.73 (95% CI: 2.53-17.87) for bladder cancer, 1.66 (95% CI: 1.54-1.78) for apoplexy and 1.67 (95% CI: 1.51-1.86) for heart disease. The results of the present study suggest that the environmental factors shared by family members for a long time may contribute to familial aggregation of cancer and some chronic diseases.

The clinical application of photodynamic therapy (PDT) began in the late 1970's. Hematoporphyrin derivative has been used as a photosensitizer and recently Photofrin II (Dihematoporphyrin ether, DHE) was also developed as a second generation photosensitizer. The argon dye laseris used to excite the photosensitizer, however an eximer dye laser was recently developed as more effective laser. In a multicenter research study project team (7 institutions) on photodynamic therapy organized by the Ministry of Health and Welfare, 133 cases of gastric cancer (including 120 cases of early stage cancer), 209 cases of lung cancer (69 cases of early stage cancer), 66 cases of esophageal cancer (22 cases of early stage cancer), 68 cases of bladder cancer (68 cases of early stage cancer), and 86 cases of other organ cancers were treated. In early stage cancer cases 77.3% showed complete remission (CR) but among those the recurrence was 15.7% in lung cancer cases and opposed to 100% CR and 22.2% recurrence in gastric cancer cases, 80% CR and no recurrence in esophageal cancer cases, and 68.6% CR and 58.3% recurrence in bladder cancer cases. Especially in limited lesions less than 1 cm in diameter, the CR was obtained in 100% and the recurrence was recognized in only 1 (2.6%) of 28 lung cancer lesions, 100% CR and no recurrence was obtained in 30 lesions of gastric cancer and also 100% CR with no recurrence was recognized in 16 lesions in bladder cancer. This study suggests that PDT has the potential to cure early stage cancer lesions.

Multi-institutional studies on clinical hyperthermia of deep-seated tumours were undertaken using 8 MHz radiofrequency capacitive heating devices (Thermotron RF-8) at seven institutions. Each institute was designated to treat specific organs. This paper contains the accumulations of the results obtained at different institutions charged for different tumours. Deep-seated tumours in the lung, stomach, pancreas, liver, urinary bladder and rectum were treated. A total of 177 cases examined from January 1985 to December 1988 included 96 cases (54%) treated with radiotherapy plus hyperthermia, among which 14 cases were pre-operative. Of 177 cases, 81 (46%) were treated with chemotherapy plus hyperthermia. Complete response (CR) and partial response (PR) were obtained in 80% of the cases with lung cancer, 39% with stomach cancer, 56% with liver cancer, 35% with pancreas cancer, 71% with urinary bladder cancer, 100% with primary rectal cancer, and 47% with recurrent rectal cancer. Thermometry was performed using two techniques; one is direct measurement of intratumour temperature in lung and liver cancers, the other is indirect measurement of intracavitary temperature for stomach, pancreas, urinary bladder and rectal cancers. Intratumour temperatures were measured in 30 of the 43 tumours of the lung and liver. The maximum tumour temperature was greater than 42 degrees C in 23 (77%) of the 30 tumours. Intracavitary temperatures were measured in 133 (99%) of the 134 tumours of stomach, pancreas, urinary bladder and rectum. An intracavitary temperature greater than 42 degrees C was obtained in 98 (73.7%) of the 133 tumours. The contribution of hyperthermia in improving the quality of life of patients under terminal care was also investigated. It was indicated that hyperthermia was one of the most effective treatment techniques for advanced or inoperable cases. In this study local control rate (LCR) was mainly discussed because the period of follow-up was only 3 years. Side-effects were observed in 37 cases (21%); main side-effects were fatty induration, pain during treatment and burn. However, no side-effects were severe enough to interrupt therapy.

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.

Painters are exposed to a range of complex chemical mixtures which include organic solvents and dye products with known carcinogenic and mutagenic potential. Trade painters or those manufacturing paints and coatings have increased rates of non-malignant diseases and cancers; including lung cancer, acute leukaemia, bladder cancer, and cancers of the oesophagus, larynx, biliary system, liver, skin, and large bowel. A series of case-control studies of painters, based on the New Zealand Cancer Registry, are presented. These concerned 19,904 male patients registered for the period 1980-4 who were aged 20 or older at the time of registration. For each cancer site studied, the registrants for all other cancer sites formed the control group. Three cancer sites were associated with work as a painter--namely, bladder tumours (odds ratio (OR) 1.52, 95% confidence interval (95% CI) 1.00-2.31), kidney and other urothelial tumours (OR 1.45, 95% CI 0.85-2.50), and multiple myeloma (OR 1.95, 95%, CI 1.05-3.65). Risks for multiple myeloma were greater among car or spray painters and signwriters (OR 2.81) compared with construction and general painters (OR 1.80). No increased risk was found for leukaemia or for respiratory, biliary, skin, or gastrointestinal cancers.

Cancer incidence in migrants to New South Wales (NSW) from individual countries within the British Isles has been compared with that in the Australian-born population using data from the NSW Central Cancer Registry for the period 1972-84. Indirectly age-standardised incidence ratios (SIR) showed that, for cancer at all sites combined, Scottish migrants had a significantly higher, and English migrants a lower, incidence than the native-born Australians. Melanoma of skin was less common in migrants from all four countries while lung cancer was more common. In all except the Irish migrants, stomach cancer was more frequent than in the Australian-born. Raised SIRs for bladder cancer were found in men from all the countries and for breast cancer in all except the Irish women but only in the English migrants were these ratios significant. English migrants differed from those from Wales, Scotland and Ireland in that, compared with the Australian-born, they had significantly lower SIRs for cancer of the colon (both sexes), head and neck, larynx and prostate (men), gallbladder and kidney (women), and a higher SIR for ovarian cancer. Bone cancer was relatively more common in men born in Wales. 'Other genital' cancers (penis and scrotum; vulva and vagina) tended to be more frequent in migrants from each country than in the Australian-born.

A 1:1 pair matched case-control study was conducted in 1988 to investigate the risk factors for bladder cancer. Cases were inpatients suffering from bladder cancer, while controls were those admitted to hospitals not due to urinary diseases and smoking-related diseases such as lung cancer, oral cancer, or throat cancer. A total of 101 pairs of cases and controls from five major hospitals in Wuhan city, matched on sex, age, and hospital, were interviewed regarding their health history, lifestyle, occupational exposures, and familial history of cancer. Bivariate analysis revealed 10 factors significantly associated with bladder cancer. Conditional logistic regression analysis showed that 5 out of the 10 factors were risk factors for bladder cancer. Cigarette smoking, history of urinary diseases, working at the unit with more than one person ever suffering from bladder cancer, and eating mo than 1.5 kilograms of meat monthly were involved highest significant risks, whereas drinking milk appeared to have negative significant association with bladder cancer.
