Swiss national cancer mortality statistics from 1951 to 1984 and survival rates from the Vaud Cancer Registry datafile over the period 1974-1980 were considered in terms of sex ratios. Overall age-standardized cancer mortality for population aged 35-64 showed only a moderate decline in males (from 230 to 221/100,000), but a substantial one in females (from 191 to 152/100,000). Mortality from most cancer sites (except gallbladder and thyroid) was persistently higher in males, the male/female ratio ranging between 1.2 for intestines, skin, brain and lympho-reticular neoplasms to about 2 for stomach or pancreas, up to 7-10 for lung and cancers related to tobacco and alcohol (mouth or pharynx, oesophagus). The sex ratio for lung cancer increased between the early 1950's and the mid 1960's, but noticeably declined thereafter, probably reflecting trends in smoking prevalence among subsequent generations of Swiss males and females. Less obvious is the substantial increase in the sex ratio for liver cancer (from 1.6 to 5.7), which was evident in younger middle age, too. Population-based cancer survival statistics indicated that for most common sites rates were appreciably higher in females than in males. Thus, better survival explains part of the advantage in cancer mortality for women. This can be related to earlier diagnosis, better compliance or responsiveness to treatment, although there is no obvious single interpretation for this generalized more favourable pattern in females.

Occupational mortality among Hong Kong males aged 15 and above were examined for the period 1979-1983, using routine death registration and census data. Age-standardized mortality ratios (SMR) and relative SMR (RSMR) were calculated for each two-digit occupational group and elevated mortality from all and various causes were highlighted. Mortality from ischaemic heart disease was strikingly associated with professional and sales-managerial occupations whereas colorectal cancers were associated with predominantly clerical and sales workers. Mortality from cancer of the buccal cavity and pharynx was elevated in fishermen as well as in farmers, food, drink and tobacco workers, mechanical fitters, and others. Excesses of liver cancer were found in doctors, fishermen and construction workers. Lung cancer deaths were particularly excessive among fishermen, plumbers and welders, construction workers and transport equipment operators. Fishermen were at high risk of death from cancers of the buccal cavity and pharynx, stomach, liver and lung, cerebrovascular diseases and cirrhosis. Miners and quarrymen experienced high mortality from pulmonary tuberculosis and chronic obstructive airways disease whereas construction workers also experienced high mortality from pulmonary tuberculosis as well as cancers of the liver, lung and bladder and non-Hodgkin's lymphomas. Transport workers were at high risk of dying from cancers of the stomach and lung, cerebrovascular diseases and diabetes mellitus. These and other associations were generally in line with those found from other similar surveys or detailed studies. The limitations of such studies are many and discussed in the context of Hong Kong.(ABSTRACT TRUNCATED AT 250 WORDS)

From 1977 to 1982, 62 patients with various advanced malignant solid tumors were treated by HD-MTX-CFR therapy and totally 129 courses were given. Majority of the patients suffered from malignant lymphoma (10), osteogenic sarcoma (11), lung cancer (16), esophageal cancer (3), breast cancer (3) and malignant melanoma (4). All were confirmed by cytology or pathology except one primary liver cancer. There were clinically measurable lesions in 59 patients for evaluation of the treatment, and 3 osteogenic sarcoma patients without metastasis were given a postoperative adjuvant chemotherapy. 33 out of 62 had received chemotherapy and/or radiotherapy before. Dose of MTX ranged from 2 to 3 gm per course in most patients and dose of CF, from 9 to 12 mg every 6 hours for 3 days. 2 (3.4%) patients achieved complete remission (1 osteogenic sarcoma and 1 malignant lymphoma) and 8 (13.6%), partial remission (1 osteogenic sarcoma, 5 malignant lymphoma, 1 esophageal cancer and 1 breast cancer) with a total response rate of 15.9%. No response was observed in all 16 lung cancers. The main side effects of HD-MTX-CFR therapy were leukopenia, thrombocytopenia, elevation of SGPT, nausea, vomiting, mucositis, skin rash, fever and fatigue. All patients were followed more than 3 years. 4 patients are still alive (9, 9, 4 and 7 years, respectively), including 3 osteogenic sarcoma patients who received postoperative adjuvant chemotherapy and 1 mycosis fungoides.

The Swedish Cancer-Environment Register was used to study time-related trends in relative risks (RRs) of cancer between 1961 and 1979 in a cohort of 254,417 Swedish men who were employed in agriculture in 1960. The reference cohort consisted of 1,725,845 Swedish men who were gainfully employed in economic activities other than agriculture or forestry in 1960. Altogether 24,763 cancers were observed in the study cohort and 146,900 in the reference cohort, giving an estimated RR for the entire study period of 0.82 (95% confidence interval: 0.81-0.83). The RR for all sites combined increased from 0.80 in 1961-73 to 0.84 in 1974-79 (P less than .01). The RR also increased over time for primary liver cancer (P less than .01), prostate cancer (P less than .01), cancer of other genital organs (P less than .01), cancer of urinary organs (P less than .01), lip cancer (P less than .05), and cancer of the nose and nasal cavities (P less than .05). For most of these sites the RR remained lower than unity. For prostate cancer, however, the RR was unity at the end of the study period. A decrease in the RR over time was observed for skin carcinomas of the trunk and limbs (P less than .05) and malignant tumors of the nervous system (P less than .05). For 27 of the 48 analyzed tumor sites the RR for the entire period 1961-79 was significantly lower than unity. The lowest RRs were seen for cancer of the pleura (0.25), cancer of the larynx (0.35), lung cancer (0.36), cancer of the hypopharynx (0.36), cancer of the floor of mouth (0.40), primary liver cancer (0.44), and cancer of the kidney pelvis (0.49). RRs significantly higher than unity were found for cancer of the lip (1.92), malignant melanoma, and carcinoma of the skin in the head and neck region (1.39 and 1.15, respectively), multiple myeloma (1.20), and cancer of the stomach (1.07).

Mitoxantrone is an anthraquinone antineoplastic agent with structural similarities to doxorubicin. It has a mechanism of action similar to the anthracyclines. Its primary elimination route is hepatic metabolism (only seven percent renal excretion) and it has a terminal half-life of approximately 40 hours. Mitoxantrone has significant activity in the treatment of metastatic breast cancer, acute leukemias, and non-Hodgkin's lymphoma. Some activity is reported in head and neck cancer, Hodgkin's, myeloma, bladder cancer, prostate cancer, non-small-cell lung cancer, and liver cancer. There is a suggestion of incomplete cross-resistance between mitoxantrone and the anthracyclines in certain neoplasms. Some activity is reported with mitoxantrone in patients refractory to the anthracyclines in breast cancer, acute leukemias, and non-Hodgkin's lymphomas. The usual doses used in solid tumors and in lymphomas are mitoxantrone 12-14 mg/m2 iv q3-4wk and in leukemias is mitoxantrone 12 mg/m2/d X 5 d iv for initial induction.

A review of epidemiological studies on the health effects of exposure to phenoxy herbicides suggests that exposure may be associated with an increased incidence of cancer and unfavorable outcomes of pregnancy. Studies on cancer have found increased risks of 5.3, 6.8 and 3.96 for soft-tissue sarcoma, 7.7 and 6.0 for stomach cancer, 2.05 for lung cancer, 4.8 for lymphoma, 2.3 for all cancers combined, and 5.2 for liver cancer after exposure to 2,4,5-T or dioxin contaminants. Several studies have suggested a possible increase in birth defects after paternal exposure. An increased risk of hydatidiform mole is suggested by Vietnamese studies on the effects of maternal exposure.

To assess the potential chronic health effects of methylene chloride, the mortality experience of a maturing 1964 to 1970 cohort of 1,013 hourly men was evaluated through 1984. On average, employees were exposed at a rate of 26 ppm (eight-hour time-weighted average) for 22 years; median latency was 30 years. Compared with the general population, no statistically significant excesses were observed for such hypothesized causes as lung cancer (14 observed v 21.0 expected), liver cancer (0 v 0.8), and ischemic heart disease (69 v 98.1); dose-response relationships based on career methylene chloride exposure and latency were not demonstrated. Among nonhypothesized causes, a significant deficit was reported for total deaths (176 v 253.2). None of the industrial referent comparisons achieved statistical significance. Sufficient power was available to detect relative risks of 1.6 for lung malignancy and 1.3 for ischemic heart disease. In contrast, there was inadequate power to identify meaningful risk levels for hepatic cancer. With 14 combined lung and liver cancer deaths observed v 36.3 predicted (P less than .0001), the mortality estimate projected from a mathematical model derived from an animal bioassay substantially overestimated cancer mortality for these sites. This inconsistency emphasizes the need to incorporate epidemiologic evidence in assessing the human health risks associated with long-term exposure to this widely used solvent.

Mortalities from selected causes from 1973 to 1982 among Koreans, Chinese, and Americans residing in Japan were compared with those of Japanese. In the Korean population, besides the well-documented excess in mortalities from liver cancer, lung cancer, liver cirrhosis and male tuberculosis, a rather prominent elevation was observed for mortalities from female tuberculosis and diabetes mellitus in both sexes. Distinctive features in the Chinese population were increased mortalities from liver cancer and female lung cancer and lowered mortality from stomach cancer, and these findings are consistent with the observations among Chinese in other areas. Mortalities from diabetes mellitus and liver cirrhosis was moderately increased in this population as well. Americans in Japan by and large showed a mortality pattern similar to that in the US although mortality from stroke among female Americans was rather elevated during the period 1973-1977. Epidemiological studies on Koreans and Chinese in Japan with reference to their lifestyle are strongly required.

In a cohort study of 5464 union organised Swedish chimney sweeps employed at any time between 1918 and 1980 mortality was studied from 1951 to 1982 with national statistics used as a reference. Follow up was possible for 98.6% of the individuals: 717 deaths were observed against 540 expected. There was an increased mortality from coronary heart disease, respiratory diseases, and several types of malignant tumours. Lung cancer mortality was significantly increased and positively correlated to the number of years employed. A fivefold risk increase for oesophageal cancer and liver cancer was found. The increased mortality could be attributed to exposure to combustion products in the work environment but not to smoking habits.

To evaluate occupational cancer mortality in British Columbia, we calculated the age-standardized proportional mortality ratios (PMR) and proportional cancer mortality ratios (PCMR) for 4,091 woodworkers, 5,457 loggers, 2,020 fishermen, 4,066 farmers, and 1,912 miners. Woodworkers 20-65 years old had significantly elevated risks of death from stomach cancer (PCMR = 128, P less than .01) and non-Hodgkin's lymphoma (PCMR = 140, P less than .05). Loggers appear to have an elevated risk of death from nasal sinus tumors (PCMR = 364, P less than .05). Fishermen had an elevated risk of stomach cancer (PCMR = 168, P less than .01). Farmers in British Columbia appeared to have excess risks of stomach (PCMR = 136, P less than .01) and liver cancer (PCMR = 173, P less than .05), but decreased risk from lung cancer (PCMR = 76, P less than .01). Miners had an elevated risk of death from lung cancer (PCMR = 127, P less than .05) and primary eye tumors (PCMR = 569, P less than .05).
