The causes of mortality of 3,649 white and 397 non-white male U.S. embalmers and funeral directors, who had died between 1975 and 1985, were examined in a proportional mortality study. Non-significant excesses were found for malignancies of the buccal cavity and pharynx (PMR = 120) and for nasopharyngeal cancer (PMR = 216). No sinonasal cancers were observed, while 1.7 were expected. A statistically significant excess of colon cancer (PMR = 127) was found and a non-significant excess of brain and other CNS cancer was noted among whites only (PMR = 123). Statistically significant excesses of malignancies of the lymphatic and hematopoietic systems were found in whites (PMR = 131) and non-whites (PMR = 241). Myeloid leukemia (PMR = 157) and leukemia of other and unspecified cell types (PMR = 228) were in excess, while no excess of lymphatic leukemia was noted. Elevations in risk were also found for non-Hodgkin's lymphoma, polycythemia vera, and myelofibrosis. Non-whites showed a marked excess of multiple myeloma (PMR = 369). Chronic nephritis was in excess among whites (PMR = 215) and non-whites (PMR = 257). No excess of cirrhosis of the liver was found. Excesses of malignancies of the lymphatic and hematopoietic systems could not be directly related to job held in the funeral industry. Further case-control studies are planned to rule out the possibility that the observed associations are artifactual, by assessing the association between specific work practices and disease risk.

Neoplasia may develop in patients with malignant hematologic disorders, during remission after radio and/or chemotherapy. A multifactorial origin related to therapy may be postulated. From 1978 to 1987, among 142 patients with malignant hematologic disorders (Hodgkin lymphoma 33, non-Hodgkin lymphoma 51, Multiple Myeloma 35 and Chronic Myeloid Leukemia 31) we observed 3 patients developing another neoplasia. An additional patient with acute non-lymphatic leukemia had been submitted to chemotherapy for gastric cancer. Four other patients with double neoplasia, one of them a hematologic one, had not been submitted to chemotherapy. The lack of national registries for neoplastic diseases precludes an estimation of the odd ratios involved in our findings.

A cancer registry cohort of 16,704 cases of invasive carcinoma of the uterine cervix and 56,116 cases of in situ carcinomas of the uterine cervix was followed up and second new primary cancers were recorded. The invasive carcinomas contributed 127,118 woman-years at risk and the in situ carcinomas contributed 453,362 woman-years at risk. The main treatment for the invasive carcinomas had been radiotherapy and for the in situ carcinomas, conization and other types of surgical intervention. 767 new primaries occurred after treatment of invasive carcinoma of the uterine cervix, compared with 644.5 expected. O/E is 1.19. After the in situ carcinomas, 1,421 malignant tumors were observed, vs. 1,188.0 expected (O/E 1.19). If, however, cases of invasive carcinoma of the uterine cervix after in situ carcinomas are excluded, the ratio observed/expected is 1.10. For some sites the increased observed/expected ratios were found after both invasive and in situ carcinomas, which speaks for some common carcinogenic effect other than irradiation (for instance, in bronchus and trachea, pharynx, nose, sinus and larynx, but also in rectum, urinary bladder, other female genital organs, pancreas, lymphosarcoma, as well as acute and non-lymphatic leukemia). A lower risk than expected--after both in situ and invasive carcinoma of the uterine cervix--is observed for breast cancer, cancer of the corpus uteri and for multiple myeloma. However, analyses based on time since treatment provide evidence of a carcinogenic effect of irradiation, especially in intensively irradiated organs such as bladder, rectum, corpus uteri and ovary, and also for acute and non-lymphatic leukemia.

Thirty patients with malignant hematological disease underwent allogeneic bone marrow transplantation following Busulphan (Bu) and Cyclophosphamide (Cy). The diseases were chronic myelogenous leukemia, acute lymphoblastic and non lymphoblastic leukemia, myelofibrosis and multiple myeloma in complete remission and in relapse. A sustained disease-free survival (DFS) was achieved in 0/5 acute leukemia patients transplanted in relapse, in 5/7 acute leukemia patients transplanted in remission (600-1550 days) and in 6/9 CML patients transplanted in the chronic phase of the disease (500-950 days). A sustained DFS was also achieved in one 2nd BMT for relapsed CML. The data suggest that the Bu-Cy protocol combines high tumor ablative capability with toxicity comparable to previously described conditioning regimens for allogeneic BMT, particularly in diseases involving a great expansion of the bone marrow.

Nested case-control studies of non-Hodgkin's lymphoma (52 cases), multiple myeloma (20 cases), nonlymphocytic leukemia (39 cases), and lymphocytic leukemia (18 cases) were conducted within a cohort of employed men from two chemical manufacturing facilities and a research and development center. Exposure odds ratios were examined in relation to 111 work areas, 21 specific chemicals, and 52 chemical activity groups. Associations were observed for a maintenance and construction subgroup (non-Hodgkin's lymphoma) and a chlorohydrin production unit (nonlymphocytic leukemia). The odds ratio for the association of "foremen and others" with non-Hodgkin's lymphoma was 3.2 (CI95 = 1.47-7.2) based on 11 cases. A duration-response trend was observed for the chlorohydrin unit with three of four cases assigned 5+ years to that unit. An association between non-Hodgkin's lymphoma and assignment to strong acid alcohol production units (OR = 8.3; CI95 = 2.3-30.7) was not supported by a duration-response trend. Two highly correlated chemical groups, antioxidants (five cases) and nitriles (four cases), were over-represented among multiple myeloma cases. A duration effect was observed. However, examination of work histories did not reveal common jobs or departments among these cases.

Epstein-Barr virus (EBV) can induce a broad spectrum of hematological diseases, especially in immune deficient patients. We assayed for receptor for EBV (EBVR) using fluoresceinated viral particles on 44 human hematopoietic cell lines derived from patients with T, B, and non-T, non-B acute lymphocytic leukemia (ALL), non-lymphoid leukemia, Burkitt lymphoma, myeloma and several unique lines we and others have recently developed. All 31 EBV nuclear-associated antigen (EBNA) negative cell lines were of neoplastic origin. Seven of 13 EBNA-positive cell lines were of normal cell origin. Four of 25 non-B (surface immunoglobulin negative) EBNA-negative neoplastic cell lines were EBVR-positive. Three of six EBNA-negative B-cell (surface immunoglobulin positive) lines were EBVR-positive. Nine of 13 EBNA-positive Burkitt and non-Burkitt cell lines strongly expressed EBVR. Four EBNA-positive Burkitt lymphoma cell lines exhibited EBVR only to a limited degree. Studies of the cell lines for EBVR, complement receptors (CR) and surface immunoglobulin (SIg) revealed that presence of SIg does not obligate the presence of EBVR. Functional EBVR accompanied SIg among EBNA-negative cell lines. SIg-negative cell lines can possess EBVR. Fourteen of 16 EBVR-positive lines were also positive for CR. The EBVR assay is a useful tool for assessing the potential role of EBV in the induction of hematopoietic disorders.

BALB/c mice were immunized with uninduced K562 erythroleukemia cells and hybridomas were isolated after fusion of immune spleen cells to P3/NS1 murine myeloma cells. One selected hybrid, designated 10L-30, secreted an antibody of subclass immunoglobulin G2a which was specific for hematopoietic cells. Analysis of 10L-30 binding by complement-mediated cytotoxicity, indirect immunofluorescence, solid-phase radioimmunoassay, and mixed hemadsorption assay indicated that the 10L-30 antigen was expressed on the myeloid cell lines K562, KG-1A, KG-1, some B- and T-lymphoid cell lines, and all normal human peripheral blood T-lymphocyte samples tested, but was absent on the more differentiated myeloid cell lines HL-60, ML-2, ML-3, and normal blood granulocytes. Induction of erythroid differentiation in hemin-treated K562 cells caused a 10-fold reduction in 10L-30 binding. Human erythroid and granulocytic progenitor cells, platelets, erythrocytes, and reticulocytes were nonreactive, as were a variety of nonhematopoietic human tumor cell lines. Freshly isolated leukemic bone marrow samples from patients with M5 (2 of 5), M6 (2 of 2), acute lymphoid leukemia (9 of 14), and chronic myeloid leukemia in lymphoid blast crisis (1 of 1) were 10L-30 positive. The combined evidence indicates that the 10L-30 antigen is a normal, hematopoietic-specific differentiation antigen which is strongly expressed on both immature cells of the myeloid lineage and more generally in lymphoid ontogeny. The 10L-30 antigen may be a useful marker of both normal and leukemic hematopoietic differentiation.

The numbers of second cancers among 182,040 women treated for cervical cancer that were reported to 15 cancer registries in 8 countries were compared to the numbers expected had the same risk prevailed as in the general population. A small 9% excess of second cancers (5,146 observed vs. 4,736 expected) occurred 1 or more years after treatment. Large radiation doses experienced by 82,616 women did not dramatically alter their risk of developing a second cancer; at most, about 162 of 3,324 second cancers (approximately equal to 5%) could be attributed to radiation. The relative risk (RR = 1.1) for developing cancer in organs close to the cervix that had received high radiation exposures--most notably, the bladder, rectum, uterine corpus, ovary, small intestine, bone, and connective tissue--and for developing multiple myeloma increased with time since treatment. No similar increase was seen for 99,424 women not treated with radiation. Only a slight excess of acute and non-lymphocytic leukemia was found among irradiated women (RR = 1.3), and substantially fewer cases were observed than expected on the basis of current radiation risk estimates. The small risk of leukemia may be associated with low doses of radiation absorbed by the bone marrow outside the pelvis, inasmuch as the marrow in the pelvis may have been destroyed or rendered inactive by very large radiotherapy exposures. There was little evidence of a radiation effect for cancers of the stomach, colon, liver, and gallbladder, for melanoma and other skin cancers, or for chronic lymphocytic leukemia despite substantial exposures. An excess of thyroid cancer possibly was related to the low dose received by this organ. Ovarian damage caused by radiation may have been responsible for a low breast cancer risk (RR = 0.7), which was evident even among postmenopausal women. A substantial excess of lung cancer (RR = 3.7) largely may be due to misclassification of metastases and the confounding influence of cigarette smoking. Women who were under 30 or over 50 years of age when irradiated were at greatest absolute risk for developing a second cancer. The RR, however, was higher among those under age 30 years at exposure (RR = 3.9) than among older women. The expression period for radiation-induced solid tumors appeared to continue to the end of life.

In 1982, the number of deaths from hematopoietic neoplasms was 5,885 for males and 4,237 for females, which corresponded to about 6% of all malignant neoplasms. The increase in the age-adjusted death rate in the last 10 years was highest for lymphatic leukemia (1.8 times), followed by multiple myeloma (1.7 times), malignant lymphomas (1.3 times) and myelogenous leukemia (1.1 times). In the old-age group, i.e., over 70, the death rate for all types of hematopoietic neoplasms markedly during this period, particularly for multiple myeloma. In children, however, an increase in lymphatic leukemia and a decrease in decrease in myelogenous leukemia were observed. Geographical marked excess in the death rates for malignant lymphomas and lymphatic leukemia in the Kyushu district, especially in the middle- and old-age groups. This may be attributed to the high incidence of adult T-cell leukemia/lymphoma in the southwestern part of Japan. The age-adjusted death rate for malignant lymphomas was slightly higher in rural areas than in urban areas in males in Kyushu.

In Denmark, approximately 5% of all malignant neoplasms occur within the lymphatic and hematopoietic tissues. Between 1943 and 1980, 23,367 persons with these diseases fulfilled the criteria for entering the study. The risk of developing a second primary cancer was significantly increased only after Hodgkin's disease [relative risk (RR) = 1.6], whereas no increase was found after non-Hodgkin's lymphoma [(NHL); RR = 1.0] or leukemia (RR = 1.1), and a significant deficit occurred after multiple myeloma (RR = 0.8). All initial cancer sites showed a higher incidence of second primary cancers among males than females. Significant elevated risks for acute non-lymphocytic leukemia occurred after Hodgkin's disease (RR = 17), NHL (3.8), and multiple myeloma (9.1). Among persons initially diagnosed with leukemia, NHL was significantly elevated (RR = 2.6). However, these RR should be regarded as minimum figures due to the likelihood of serious underreporting of second primary hematologic cancers in Denmark. The secondary leukemias were likely induced by the treatment of the first primary cancer (chemotherapy, radiotherapy), but common etiologies, misclassification, or progression of the initial cancer cannot be ruled out entirely. Other second primary cancers found to be above expectation following Hodgkin's disease were cancers of the pancreas, lung, and urinary bladder. The risk for bladder cancer increased with time, which suggested a causal relation to radiation or chemotherapy, or both. Cancers of the colon and rectum following NHL and female breast cancer following leukemia occurred below expectation and remain unexplained.
