A mortality odds ratio (MOR) study of race-specific cancer risk among firefighters was conducted using 1984-1993 death certificate data from 24 states. The Bureau of the Census Index of Industries and Occupations was used to code occupation on death certificates. The overall cancer mortality was slightly elevated among white firefighters (MOR = 1.1; 95% confidence interval [CI] = 1.1-1.2), but the increase in overall cancer mortality among black firefighters was not significant (MOR = 1.2; 95% CI = 0.9-1.5). Only prostate cancer risk was elevated in both groups (whites: MOR = 1.2; 95% CI = 1.0-1.3; blacks: MOR = 1.9; 95% CI = 1.2-3.2). Among white firefighters, elevated site-specific cancer mortality risks were found for the following cancer sites: lip (MOR = 5.9; 95% CI = 1.9-18.3), pancreas (MOR = 1.2; 95% CI = 1.0-1.5), soft tissue sarcoma (MOR = 1.6; 95% CI = 1.0-2.7), melanoma (MOR = 1.4; 95% CI = 1.0-1.9), kidney and renal pelvis (MOR = 1.3; 95% CI = 1.0-1.7), non-Hodgkin's lymphoma (MOR = 1.4; 95% CI = 1.1-1.7), and Hodgkin's disease (MOR = 2.4; 95% CI = 1.4-4.1). We also observed a slightly elevated risk for bronchus and lung cancer (MOR = 1.1; 95% CI = 1.0-1.2). Among black firefighters, excess risks were found for cancers of the brain and central nervous system (MOR = 6.9; 95% CI = 3.0-16.0), colon (MOR = 2.1; 95% CI = 1.1-4.0), and nasopharynx (MOR = 7.6; 95% CI = 1.3-46.4). Future studies are needed to confirm the existence of differential cancer mortality risks among firefighters of different race/ethnic subpopulations.

Although the incidence of classic Kaposi's sarcoma (CKS) has been investigated, its occurrence following a primary neoplasm and its association with this first neoplasm need to be determined. We analyzed a series of 124 patients with a secondary CKS (8.4% of a total of 1485 incident cases) which occurred between 1961 and 1992 in the Jewish Israeli population. Data on first neoplasms and subsequent Kaposi's sarcoma were retrieved from the Israel Cancer Registry. Acquired-immune-deficiency-syndrome-related Kaposi's sarcomas were excluded from the case series. Four controls were randomly selected for each CKS case among all Cancer Registry cases free from a second neoplasm at the time of diagnosis of the CKS in the case, and matched on gender, year of birth and year of diagnosis of the first neoplasm. The average time lapse between first neoplasm and secondary CKS was 4.5 years, being shorter for prostate cancer and for hematopoietic malignancies. As compared with Israel-born Jews, the risk of a subsequent CKS was significantly increased in immigrants [odds ratio (OR) 3.0]; this risk was particularly high in immigrants from the former Soviet Union (OR 9.4) and Poland (OR 7.0). There was no clear trend with age at immigration; however, low age at immigration and a short length of stay in Israel endowed a higher risk of developing a secondary CKS, markedly among patients suffering from solid tumors as the first primary. There was an excess of secondary CKS following a non-Hodgkin's lymphoma (OR 5.3), a Hodgkin's lymphoma (OR 7.5), a leukemia (OR 5.3) or a breast cancer (OR 2.2). Cancer patients with a first primary in the lung, colon, stomach, larynx, liver, pancreas or kidney showed secondary CKS less frequently. Despite the lack of control of therapy for the first neoplasm, development of secondary CKS seems to be mediated by mechanisms similar to those for hematopoietic neoplasms and selected nonhematopoietic neoplasms, such as breast cancer. The trend toward increased risk after a short time lapse and the difference in risk among immigrants indicate that genetic susceptibility is part of the complex interplay between cellular proliferation and control systems.

This study is a standardized incidence ratio (SIR) analysis of cancer incidence of licensed pesticide applicators in Florida, compared with that of Florida's general population. Through extensive data linkages, 33,658 applicators were assembled who had 1266 incident cancers and 279,397 person-years from January 1, 1975, to December 31, 1993. Disease risk from ethanol and tobacco use were significantly decreased. Among males, prostate cancer (SIR = 1.91; 95% confidence interval [CI], 1.72-2.13) and testicular cancer (SIR = 2.48; 95% CI, 1.57-3.72) were significantly elevated. No confirmed cases of soft tissue sarcoma (STS) were found, and the incidence of non-Hodgkin's lymphoma was not increased. There were few female applicators; nevertheless, cervical cancer incidence (SIR = 3.69; 95% CI, 1.84-6.61) was significantly increased, while the incidence of breast cancer was significantly decreased. Cancers that have been associated with estrogen disrupters were found in male, but not female, pesticide applicators. The lack of soft tissue sarcoma is at odds with prior literature associated with the use of phenoxy herbicides.

The objectives of this study were to investigate the effect of family history on prostate cancer risk, to estimate the incidence of hereditary prostate cancer in southern Sweden and to assess the reliability of self-reported family history of prostate cancer. The study included consecutive prostate cancer patients and age-matched control subjects from a geographically defined population. The controls consisted of 1 male patient with malignant melanoma or non-Hodgkin's lymphoma and 1 male from the community per prostate cancer case. Family history was assessed with questionnaires, and diagnoses of fathers and brothers of cases were validated by the Southern Swedish Regional Tumour Registry. Among fathers and brothers whose names and birth dates were available, 56 (92%) of the 61 reported prostate cancer diagnoses were verified. Fifteen per cent of 356 cases and 5.0% of 712 controls reported at least 1 case of prostate cancer among their brothers or fathers, giving a relative risk of 3.2 (95% confidence interval 2.1-5.1). The relative risk increased with decreasing age at diagnosis of the patient. Based on the pedigree, 3.1% of the 356 patients were classified as having hereditary prostate cancer. This proportion was significantly higher among patients diagnosed before the age of 60 years (7.1%) than among older patients (2.2%). We conclude that there is a substantially increased risk of prostate cancer for sons and brothers of prostate cancer patients. The risk increases with decreasing age at diagnosis of the patient as an effect of a higher prevalence of hereditary prostate among early onset cases. Furthermore, we found self-reported family history of prostate cancer to be a valid estimate of the true incidence of prostate cancer in fathers and brothers of men with prostate cancer.

A nationwide, computer-based survey of all total joint arthroplasties performed in Finland has been carried out since January 1980. From these records, a cohort of 9,444 patients, with 51,756 person-years, after primary operation with a total polyethylene-on-metal knee arthroplasty (TKA) was followed up for cancer through the Finnish Cancer Register up to December 31, 1996. During the follow-up, 706 cancers were observed. The expected number, based on national rates, was 719; therefore, the standardized incidence ratio (SIR) for all cancers was 0.98. The SIRs for non-Hodgkin's lymphoma (1.40), Hodgkin's disease (1.24) and multiple myeloma (1.54) were increased, but only that of non-Hodgkin's lymphoma was statistically significant 3-10 years after the operation. The numbers of observed cases of prostate cancer exceeded that of expected, with a SIR value of 1.49. A low SIR of lung cancer was observed among men, especially during the first 3 years (0.61), but not in women. The SIR for colon cancer was below unity in women only (SIR 0.70). The SIR for cancer of the urinary organs was close to unity (0.97). SIR relating to soft tissue and bone cancer did not differ significantly from unity, and none of the 6 sarcomas was observed at the site of a prosthesis. The overall cancer risk after TKA done for primary osteoarthrosis seems not to be increased. The increases in lymphoma and prostate cancer risk, however, are observations that could be related to TKA and justify further follow-up of the cohort.

Calpain is a calcium-dependent cysteine protease that is implicated in calcium-dependent cell death, and calpain inhibitors are generally considered as inhibitors of apoptosis. To the contrary, in the present study, we found that calpain inhibitor II (CPI-2) triggers rapid apoptosis in acute lymphoblastic leukemia (ALL) and non-Hodgkin's lymphoma (NHL) cells. All target cell lines were killed by CPI-2, including: ALL-1, a multidrug-resistant BCR-ABL fusion transcript-positive t(9;22) pro-B ALL cell line; RS4;11, a highly radiation-resistant MLL-AF4 fusion transcript-positive t(4;11) pre-pre B ALL cell line; RAMOS, a highly radiation-resistant and p53-deficient Burkitt's lymphoma cell line; DAUDI, a Burkitt's leukemia/lymphoma cell line; NALM-6, a pre-B ALL cell line; and JURKAT and MOLT-3, two T-lineage ALL/NHL cell lines. CPI-2-induced apoptosis in LYN-deficient and BTK-deficient subclones of the DT-40 lymphoma B cell line as effectively as it did in wild-type DT-40 cells. Thus, CPI-2-induced apoptosis is not dependent on the protein tyrosine kinases LYN or BTK. Notably, caspase inhibitor I effectively inhibited CPI-2-induced apoptosis, suggesting that the inhibition of a CPI-2-susceptible protease results in caspase activation, leading to apoptosis in ALL/NHL cells. Unlike the high calpain-expressing ALL/NHL cell lines, myeloid leukemia cell lines HL-60/AML, K562/CML, and U937/AMML, or solid tumor cell lines BT-20/breast cancer, PC-3/prostate cancer, U373/glioblastoma, and HeLa/epitheloid cancer, were not susceptible to the cytotoxicity of CPI-2. Taken together, our results identify calpain as a new molecular target for the treatment of ALL and NHL. CPI-2 and its analogues represent a promising new class of antileukemia/lymphoma agents that deserves further development.

In 1989 we published a critical review of cancer epidemiology in petroleum workers, which included as a component of the review a meta-analysis by cancer site. Subsequently we have completed three additional reviews and meta-analyses on cell-type-specific leukemias (1995), multiple myeloma (1997), and non-Hodgkin's lymphoma (2000). The objective of the present investigation was to update our 1989 review and meta-analysis of nonlymphohematopoietic cancers in cohort studies of petroleum workers. Included in the present investigation were cohort studies of petroleum workers from the United States, the United Kingdom, Canada, Australia, Finland, Sweden, and Italy. Individual studies were reviewed with regard to specific cancer sites. For each cancer of interest, risk ratios from the individual studies were presented. In some studies, subcohort analyses stratified by exposure parameters such as length of employment, job category, and hire year were also reported. These subcohort or stratified analyses were reviewed and the results of these analyses were taken into consideration in our interpretation. In addition to the qualitative review of individual studies, a meta-analysis was performed to combine data from individual cohort studies of petroleum workers. The primary purpose of the meta-analysis was to provide a summary measure of risk for each cancer site. Based on a review and meta-analyses of cohort studies of more than 350,000 petroleum workers in the United States, the United Kingdom, Canada, Australia, Finland, Sweden, and Italy, we concluded that there was no increased mortality from digestive cancers (stomach, large intestine, liver, or pancreas), lung cancer, bladder cancer, kidney cancer, or brain cancer. The summary standardized mortality ratios for these cancer sites were all below unity. Significant increases of melanoma mortality were reported in some small groups of refinery workers in the United Kingdom and upstream operation workers in Canada, but no responsible agent(s) had been identified. The observed mortality from skin cancer in all other studies was similar to the expected. In particular, no significant increase of skin cancer mortality was reported in any of the U.S. studies. Elevated mortality from prostate cancer was noted in short-term workers at a U.S. refinery and in short-term workers employed in certain crafts at U.S. crude oil operations. However, the absence of an upward trend by length of employment in these workers argued against an association between exposure to petroleum products and prostate cancer. For all petroleum workers as a whole, mortality from prostate cancer was as expected.

We present a white male patient with an initial prostate-specific antigen level of 69 ng/ml, referred for urological evaluation. He was found to be free of prostatitis but diagnosed for prostate adenocarcinoma without any indications of metastatic disease. Lymphadenectomy then revealed lymphadenopathy of low-grade non-Hodgkin's lymphoma. Five-year follow-up after radical retropubic prostatectomy (RRP) showed no evidence of metastatic or local prostate cancer recurrence. In addition, no radiation or chemotherapy was required for his lymphoma. Although RRP is a viable option in this unique case, the outcome thus far suggests that it should be considered a primary therapeutic modality.

Over the past 5 years there has been a renewed interest in the use of monoclonal antibodies and immunoconjugates in the treatment of nonhematologic malignancies. This enthusiasm has stemmed from advances in recombinant technology allowing for the production of chimeric and humanized antibodies, from Food and Drug Administration approval of radioimmunoconjugates for use in diagnosis and staging in colorectal, ovarian, and prostate cancer, from studies demonstrating durable response rates in lymphoma and breast cancer, and from trials demonstrating marked efficacy of radiolabeled antibodies in the treatment of non-Hodgkin's lymphoma. Part of the success of chimeric and humanized antibodies in treating solid tumors relates to the lack of human antimouse antibody formation along with enhanced immunogenic effector mechanisms. The pitfalls underlying early trials of murine monoclonal antibodies in solid tumors and newer antibody approaches using unique antigen targets, bifunctional constructs, and alternative routes of antibody administration will be discussed.

Arsenic trioxide inhibits growth and promotes apoptosis in many different cancer cell lines. The National Cancer Institute is working cooperatively with research centers across the U.S. to evaluate its clinical activity in hematologic malignancies, such as acute promyelocytic leukemia, acute myeloid leukemia, acute lymphocytic leukemia, chronic myelogenous leukemia, non-Hodgkin's lymphoma, Hodgkin's disease, chronic lymphocytic leukemia, myelodysplastic syndrome, and multiple myeloma. It is also supporting research in solid tumors, such as advanced hormone-refractory prostate cancer and renal cell cancer and in cervical cancer and refractory transitional cell carcinoma of the bladder. The safety and pharmacokinetics of arsenic trioxide are also being evaluated in pediatric patients with refractory leukemia and lymphoma. The results of these ongoing studies should provide important insights into the clinical utility of arsenic trioxide in these diseases.
