Two brothers developed multiple primary neoplasms in childhood; one had glioblastoma and non-Hodgkin's lymphoma at age 11 years, and the other brain tumor and acute leukemia at six years. A third brother died with myelogenous leukemia at thre years, and a fourth with cyanotic congenital heart disease at 11 weeks. Each child also had at least one hamartomatous lesion of the skin. The clinical features suggested von Recklinghausen's neurofibromatosis or other inherited cancer syndrome, but laboratory studies identified no markers of susceptibility to familial neoplasia.

A cohort of 12,110 male workers employed 1 or more years in eight styrene-butadiene polymer (SBR) manufacturing plants in the United States and Canada has been followed for mortality over a 40-year period, 1943 to 1982. The all-cause mortality of these workers was low [standardized mortality ratio (SMR) = 0.81] compared to that of the general population. However, some specific sites of cancers had SMRs that exceeded 1.00. These sites were then examined by major work divisions. The sites of interest included leukemia and non-Hodgkin's lymphoma in whites. The SMRs for cancers of the digestive tract were higher than expected, especially esophageal cancer in whites and stomach cancer in blacks. The SMR for arteriosclerotic heart disease in black workers was significantly higher than would be expected based on general population rates. Employees were assigned to a work area based on job longest held. The SMRs for specific diseases differed by work area. Production workers showed increased SMRs for hematologic neoplasms and maintenance workers, for digestive cancers. A significant excess SMR for arteriosclerotic heart disease occurred only in black maintenance workers, although excess mortality from this disease occurred in blacks regardless of where they worked the longest. A significant excess SMR for rheumatic heart disease was associated with work in the combined, all-other work areas. For many causes of death, there were significant deficits in the SMRs.

Cause specific mortality was investigated among 36,622 members of a national furniture workers' union who were first employed in unionised shops between 1946 and 1962. Overall mortality for each race and sex group was less than expected when compared with United States death rates (white men SMR = 0.8, black men SMR = 0.7, white women SMR = 0.8, black women SMR = 0.5); however, raised risks were observed among white men employed in specific types of furniture industries and followed up for 20 or more years after first employment. Lymphatic and haematopoietic cancers were significantly raised (SMR = 1.8) among wood furniture workers followed up for at least 20 years due to excess deaths from leukaemia (SMR = 2.0) and non-Hodgkin's lymphoma (SMR = 2.0). Mortality from acute myeloid leukaemia was particularly high in this group (SMR = 4.7) based on six observed cases. Metal furniture workers followed up for at least 20 years experienced a significant excess of all cancers combined (SMR = 1.6), with non-significant increases in cancers of the lung, stomach, and colorectum. This group also had non-significant excesses of liver cirrhosis, arteriosclerotic heart disease, and cerebrovascular disease. Nasal cancer was not found to be significantly raised in this cohort, though the average follow up period may not have been sufficient to detect an excess risk for this uncommon tumour.

43-year-old male with non-Hodgkin's lymphoma which was resistant to standard treatment received high-dose chemotherapy followed by autologous stem cell transplantation. He had a past history of nephrectomy due to renal cell carcinoma. He had received adriamycin at a total dose of 280mg/m2, but had no episode of heart disease. His chest radiograph, electrocardiogram and serum creatinine were within normal ranges at the start of high-dose chemotherapy. He was given 120 mg/kg of cyclophosphamide (CPM) over two days. Serum creatinine levels elevated two days before transplantation, and he felt discomfort of the chest followed by severe arrhythmia. He died of heart failure one day after the transplantation. Postmortem examination revealed diffuse myocardial hemorrhage with degeneration and necrosis of the heart muscle. CPM is one of the useful antitumor alkylating agents for the treatment of malignant neoplasms. Although conventional doses of CPM can be used without adverse cardiac effects, high-dose CPM has been reported to induce cardiotoxicity in a few cases. Patients often develop fatal acute heart failure. For the safe use of high-dose CPM, we must consider about the dosing schedule, early detection of adverse cardiac effects, and patient risk factors.

A proportionate mortality study of a cohort of golf course superintendents was conducted using death certificates for 686 deceased members of the Golf Course Superintendents Association of America who died from 1970 to 1992. White males were included in the study population from all 50 states. The study objective was to compare mortality from this cohort to the general U.S. white male population. The proportionate mortality ratio (PMR) for all types of cancer was 136 (CI: 121, 152). Significant excess mortality from smoking-related diseases was observed. The PMR for arteriosclerotic heart disease was 140, which was significantly elevated (CI: 127, 155). In addition, the PMR for all respiratory diseases was 176 (CI: 135,230), while the PMR for emphysema was 186 (CI: 101,342). The PMR for lung cancer was 117 (CI: 93, 148). Mortality for four cancer types--brain, lymphoma (non-Hodgkin's lymphoma, NHL), prostate, and large intestine--occurred at elevated levels within this cohort: brain cancer PMR = 234 (CI: 121,454), non-Hodgkin's lymphoma (NHL) PMR = 237 (CI: 137,410), prostate cancer PMR = 293 (CI: 187,460), and large intestine cancer PMR = 175 (CI: 125,245). The PMR for diseases of the nervous system was 202 (CI: 123,333). A similar pattern of elevated NHL, brain, and prostate cancer mortality along with excess deaths from diseases of the nervous system has been noted among other occupational cohorts exposed to pesticides.

In response to reports linking non-Hodgkin's lymphoma (NHL) and the herbicide 2,4-dichlorophenoxyacetic acid, a retrospective cohort mortality study of 32,600 employees of a lawn care company was conducted. The cohort was generally young with short-duration employment and follow-up. In comparison to the US population, the cohort had significantly decreased mortality from all causes of death combined (307 deaths), arteriosclerotic heart disease, and accidents. There were 45 cancer deaths (59.6 expected, standardized mortality ratio [SMR] = 0.76, 95% confidence interval [CI] = 0.55, 1.01). Bladder cancer mortality was significantly increased, but two of the three observed deaths had no direct occupational contact with pesticides. There were four deaths due to NHL (SMR = 1.14, CI = 0.31, 2.91); three were male lawn applicators (SMR = 1.63, CI = 0.33, 4.77), with two of the applicators employed for three or more years (SMR = 7.11, CI = 1.78, 28.42). No other cause of death was significantly elevated among lawn applicators as a group or among those employed for three or more years. Although based on very small numbers and perhaps due to chance, the NHL excess is consistent with several earlier studies.

The purpose of this historical case series study was to evaluate the association of age on delivered dose intensity of initial CHOP (cyclophosphamide/doxorubicin/ vincristine/prednisone) chemotherapy and the occurrence of hospitalizations for febrile neutropenia for patients with intermediate-grade non-Hodgkin's lymphoma (NHL). Findings are reported for 12 managed community and academic practices. Medical records of 930 NHL patients not enrolled on clinical trial protocols were reviewed. We reported on 577 of the study patients (62%) who received initial CHOP chemotherapy. Median age of the patients was 65.1 years. Older patients (age > or = 65 years) had more hospitalizations for febrile neutropenia (28% vs. 16%; P < 0.05) than younger patients (age, 18-64 years). In patients with advanced-stage NHL (stage III/IV), older patients received fewer cycles of CHOP (< 6 cycles, 35% vs. 22%; P < 0.05) than younger patients. Older patients were planned for lower average relative dose intensity (ARDI < or = 80%; P < 0.05) and had more heart disease and comorbid conditions (P < 0.05) than younger patients. Multiple logistic regression models showed that older patients were more likely to receive a lower dose intensity (ARDI < or = 80%; odds ratio = 2.46, 95% confidence interval [CI]: 1.62-3.72) during their first 3 cycles of therapy and to experience more hospitalizations for febrile neutropenia (odds ratio = 2.17, 95% CI: 1.43-3.30). We found the dose intensity of delivered CHOP chemotherapy for elderly patients to be less than standard CHOP therapy and the risk of hospitalizations for febrile neutropenia to be greater than in younger patients. Prospective clinical trials examining supportive care measures, such as colony-stimulating factor, for elderly NHL patients are recommended.

Most public health statements regarding exposure to solar ultraviolet radiation (UVR) recommend avoiding it, especially at midday, and using sunscreen. Excess UVR is a primary risk factor for skin cancers, premature photoageing and the development of cataracts. In addition, some people are especially sensitive to UVR, sometimes due to concomitant illness or drug therapy. However, if applied uncritically, these guidelines may actually cause more harm than good. Humans derive most of their serum 25-hydroxycholecalciferol (25(OH)D3) from solar UVB radiation (280-315 nm). Serum 25(OH)D3 metabolite levels are often inadequate for optimal health in many populations, especially those with darker skin pigmentation, those living at high latitudes, those living largely indoors and in urban areas, and during winter in all but the sunniest climates. In the absence of adequate solar UVB exposure or artificial UVB, vitamin D can be obtained from dietary sources or supplements. There is compelling evidence that low vitamin D levels lead to increased risk of developing rickets, osteoporosis and osteomaloma, 16 cancers (including cancers of breast, ovary, prostate and non-Hodgkin's lymphoma), and other chronic diseases such as psoriasis, diabetes mellitus, hypertension, heart disease, myopathy, multiple sclerosis, schizophrenia, hyperparathyroidism and susceptibility to tuberculosis. The health benefits of UVB seem to outweigh the adverse effects. The risks can be minimized by avoiding sunburn, excess UVR exposure and by attention to dietary factors, such as antioxidants and limiting energy and fat consumption. It is anticipated that increasing attention will be paid to the benefits of UVB radiation and vitamin D and that health guidelines will be revised in the near future.

This paper reviews epidemiologic studies of cancer among agricultural populations to identify possible associations and to provide a focus for future investigations. Meta-analyses of mortality surveys of farmers find excesses of several cancers, including connective tissue, non-Hodgkin's lymphoma, Hodgkin's disease, multiple myeloma and cancers of the skin, stomach, and brain, and deficits for total mortality, heart disease, total cancer, and cancers of the esophagus, colon, lung, and bladder. Meta-analyses of studies of individual cancers also support these findings, indicating a need to identify exposures and lifestyle factors that might account for this mortality pattern. Although cancer studies of other occupations that might have pesticide exposures in common with farmers show some similarities with observations among farmers, the overall patterns are quite different. This suggests that pesticides are not likely to fully explain the cancer and other disease patterns observed among farmers. Because exposures vary by type of farm operation, exposures for individual farmers can differ considerably. Studies in the future need to focus on the full range of exposures to fully understand the cancer pattern in farmers.

We used nonpegylated liposomal doxorubicin (NPLD) in cytostatic drug combinations to treat 37 patients with non-Hodgkin's lymphoma and pre-existing cardiac disorder or elderly patients with reduced physical state who were ineligible for conventional anthracycline-containing therapy. High remission rates were observed in this poor-risk population: Complete remission rates were 75% for diffuse large B cell lymphoma (DLBCL) and 55% for T/NK cell neoplasm (overall response rate of 80% and 89%, respectively). Twenty-seven patients (73%) are still alive after a median observation time of 14 months. No major cardiac or gastrointestinal toxicity was observed. Extravasation of NPLD in two patients resulted in mild inflammation without tissue damage. Hematologic toxicity was comparable to that of conventional anthracycline-containing regimens. We conclude that NPLD is highly active in combination chemotherapy for lymphoma with low cardiac toxicity in patients with pre-existing cardiac disorders or higher age. Moreover, we also observed remarkable efficacy in T/NK cell lymphomas.
