Fifty-seven patients with advanced malignant tumours were treated with ifosfamide (Holoxan) and mesna (Uromitexan) in our department from November 1979 to December 1984. This series comprised eight cases of soft tissue sarcoma, nine cases of ovarian carcinoma, five cases of non-seminomatous testicular tumour, 11 cases of bronchogenic carcinoma, three cases of renal carcinoma, seven cases of non-Hodgkin's lymphoma, two cases of skeletal fibrosarcoma, two cases of breast carcinoma, one case each of Ewing's tumour, prostatic carcinoma, seminoma, plasma cell tumour, multiple myeloma, malignant teratoma, nasopharyngeal carcinoma, Wilms's tumour, neuroblastoma and mycosis fungoides. Out of these 57 cases, 53 were evaluable. There were five complete remissions and 20 partial remissions, corresponding to a total response rate of 47%. The overall median survival time (MST) of the 53 evaluable patients was 7.5 months. The responders had a longer survival time (MST 10 months) than the non-responders (MST 4.75 months) (p greater than 0.05). Analysis of the results according to sex, age, dosage of ifosfamide and degree of histological differentiation of the tumour cells failed to show any influence of these factors on the therapeutic results. The response rate to ifosfamide found in this study might be related to the histological origin of the tumours and to whether the primary tumours had been resected. The non-seminomatous testicular tumours, non-Hodgkin's lymphomas and ovarian carcinomas showed a high response rate. The response rate was higher in the group in which the primary tumour had been resected (61%) than in the non-resected group (12%) (except the non-Hodgkin's lymphoma). The side-effects of this regimen were moderate. Dyspepsia, nausea, vomiting, myelodepression, dizziness, and alopecia were common. Cystitis could be prevented nearly completely by concomitant administration of mesna, when given correctly, for preventing side-effects of ifosfamide on the urinary system (haemorrhagic cystitis, etc.).

This paper presents a review and further analysis of a series of New Zealand case-control studies which have found elevated risks for soft tissue sarcoma (STS), non-Hodgkin's lymphoma (NHL), and acute myeloid leukemia (AML) in abattoir workers. The first published study involved 82 cases of STS (ICD 171) and found a relative risk of 2.8 (90% confidence interval 1.3-6.3). Interviews with an additional 51 cases reported here revealed a relative risk of 1.6 (90% confidence interval 0.9-3.0). Two further studies involved interviews with 100 cases of the category of NHL involving lymphosarcoma and reticulosarcoma (ICD 200) and 83 cases of other NHL (ICD 202). Relative risk estimates were 1.8 (90% confidence interval 1.1-2.9) and 1.7 (90% confidence interval 1.0-2.8), respectively. A study of 150 cases of AML (ICD 205.0) found a relative risk of 2.5 for abattoir workers (90% confidence interval 1.3-4.7). Finally, a United States cohort study found a standardized mortality ratio of 2.4 (90% confidence interval 0.8-5.4) for Hodgkin's disease (ICD 201) and 2.2 (90% confidence interval 0.8-4.5) for cancer of other lymphatic tissue (ICD 202, 203, 208) among abattoir workers. Abattoir workers are potentially exposed to oncogenic viruses, including bovine leukemia virus. Some workers may also be exposed to the animal carcinogen 2,4,6-trichlorophenol when treating pelts.

The work environment in agriculture is complex, with many potentially hazardous exposures, but the overall mortality from cancer and other causes is rather low among farmers. However, several studies have consistently indicated an excess of certain cancer forms. Lymphomas, leukemias, multiple myeloma and also malignancies of connective tissue attract special interest, as being possibly associated with the use of pesticides. Phenoxy acid herbicides may play an etiological role, especially for non-Hodgkin's lymphoma, whereas the findings are more ambiguous for Hodgkin's disease and soft-tissue sarcoma, perhaps indicating an interaction with co-factors. The issue has been controversial for many years, however, and one of its aspects involves the use of phenoxy acids in the Vietnam war. Furthermore, DDT has been associated with lung cancer in mixed exposure situations, and with chronic lymphatic leukemia. Arsenical pesticides may have caused skin cancer in vine-growers. Further studies, especially of specific user groups and producers, may avoid the complex exposure situation in agriculture.

Although it is well recognized that granulocytic sarcoma can cause localized lymphadenopathy, widespread nodal involvement by acute myelocytic leukemia (AML), clinically mimicking non-Hodgkin's lymphoma, has only been previously described twice. We report the clinicopathological, immunological, and cytochemical features of two patients who had widespread, prominent lymphadenopathy secondary to AML as well as concurrent marrow leukemia (M1 and M2). For one patient the lymphadenopathy was the predominant abnormality prompting him to seek medical attention, while the second patient had symptoms of infection following a 9-month history of myelodysplasia. The disease in both patients was aggressive; one patient survived only 1 week and the other survived only 5 weeks after diagnosis. In both cases the granulocytic sarcoma was confirmed by cytochemistry studies (naphthol ASD-chloroacetate esterase on tissue sections and myeloperoxidase on imprint smears), and electron microscopy, including morphology (both cases) or ultrastructural localization of myeloperoxidase (case 2). Non-specific esterase activity was not detected in either patient's blasts, although serum lysozyme was elevated in both cases. Immunological studies revealed reactivity of both patients' cells with panleukocyte, MY4, MY7, OKM-1, and Leu-M1 monoclonal antibodies and with alpha-1-antitrypsin and muramidase antibodies. The cells of one of these patients also reacted with anti-S-100 protein. Although the cytochemical studies indicated that both cases exhibited only myeloid differentiation, the immunological markers suggested that the tumor cells possessed some features of monocytes, perhaps explaining their propensity for widespread tumor formation. Morphological, immunological, cytochemical, and ultrastructural methods of diagnosing granulocytic sarcoma are presented.

A case of granulocytic sarcoma is reported. A 51-year-old male was found, upon laparotomy, to have a tumor mass in the terminal ileum. Nine months later, acute myelogenous leukemia (AML) was diagnosed upon a peripheral blood and bone marrow examination showing an increased number of abnormal myeloblasts. Scattered lesions of granulocytic sarcoma were found in the intestine, colon, testis, skin, gingiva and bone marrow. Chemotherapy, with multiple regimens for leukemia in combination, did not affect the tumor and the patient died 10 months following his development of overt leukemia. Detailed pathological findings are presented because of the difficulty in differentiating granulocytic sarcoma from non-Hodgkin's lymphoma.

A population-based case-control study was conducted in western Washington State to evaluate the relationship between occupational exposure of men aged 20-79 to phenoxyacetic acid herbicides and chlorinated phenols and the risks of developing soft tissue sarcoma (STS) and non-Hodgkin's lymphoma (NHL). Occupational histories and other data were obtained by personal interviews for 128 STS cases and 576 NHL cases, diagnosed between 1981 and 1984, and for 694 randomly selected controls without cancer. Among the study subjects with any past occupational exposure to phenoxyherbicides, the estimated relative risk and 95% confidence interval of developing STS was 0.80 (0.5-1.2), and of developing NHL, 1.07 (0.8-1.4). Risk estimates of developing STS and NHL associated with past chlorophenol exposure were 0.99 (0.7-1.5) and 0.99 (0.8-1.2), respectively. No increasing risk of either cancer was associated with overall duration or intensity of chemical exposure or with exposure to any specific phenoxyherbicide per se. However, estimated risks of NHL were elevated among men who had been farmers, 1.33 (1.03-1.7), forestry herbicide applicators, 4.80 (1.2-19.4), and for those potentially exposed to phenoxyherbicides in any occupation for 15 years or more during the period prior to 15 years before cancer diagnosis, 1.71 (1.04-2.8). Increased risks of NHL were also observed among those with occupational exposure to organochlorine insecticides, such as DDT [1.82 (1.04-3.2)] and organic solvents [1.35 (1.06-1.7)], and to other chemicals typically encountered in the agricultural, forestry, or wood products industries. These results demonstrate small but significantly increased risks of developing NHL in association with some occupational activities where phenoxyherbicides have been used in combination with other types of chemicals, particularly for prolonged periods. They do not demonstrate a positive association between increased cancer risks and exposure to any specific phenoxyherbicide product alone. Moreover, these findings provide no evidence of increased risks of developing NHL associated with chlorinated phenol exposure or of developing STS associated with exposure to either class of chemical.

A case of recurrent Hodgkin's disease of the "sarcomatoid" or "syncytial variant" type was seen that occurred as an extension from the mediastinum to a previously uninvolved extranodal site (breast) and pericardium after treatment of classical nodular sclerosing Hodgkin's disease based in the lymph nodes. This histologic variant was composed of sheets of large, undifferentiated neoplastic cells with few, if any, diagnostic features of nodular sclerosing Hodgkin's disease. For this reason, the differential diagnosis of this variant was difficult and included non-Hodgkin's lymphoma (peripheral T-cell lymphoma), Ki-1-positive lymphoma, medullary carcinoma, metastatic carcinoma, melanoma, and granulocytic sarcoma. Immunologic analysis by immunoperoxidase technique showed a phenotype consistent with "syncytial variant" Hodgkin's disease: Leu-M1+, Ki-1+, IL-2+, HLA-DR+, T11-, pan B-, K-, lambda-, cytokeratin-, S-100-, muramidase-.

A population-based case-control study of soft-tissue sarcoma (STS), Hodgkin's disease (HD), and non-Hodgkin's lymphoma (NHL) in Kansas found farm herbicide use to be associated with NHL (odds ratio [OR], 1.6; 95% confidence interval [CI], 0.9, 2.6). Relative risk of NHL increased significantly with number of days of herbicide exposure per year and latency. Men exposed to herbicides more than 20 days per year had a sixfold increased risk of NHL (OR, 6.0; 95% CI, 1.9, 19.5) relative to nonfarmers. Frequent users who mixed or applied the herbicides themselves had an OR of 8.0 (95% CI, 2.3, 27.9) for NHL. Excesses were associated with use of phenoxyacetic acid herbicides, specifically 2,4-dichlorophenoxyacetic acid. Neither STS nor HD was associated with pesticide exposure. This study confirms the reports from Sweden and several US states that NHL is associated with farm herbicide use, especially phenoxyacetic acids. It does not confirm the case-control studies or the cohort studies of pesticide manufacturers and Vietnam veterans linking herbicides to STS or HD.

A clinicopathologic analysis of nine patients with B-immunoblastic sarcoma (B-IBS) presenting as a bulky lymph node-based retroperitoneal mass is reported. The histologic and immunologic findings, similar to those reported in B-IBS presenting in various other nodal and extranodal sites, support the recognition of this aggressive large cell non-Hodgkin's lymphoma (NHL) as a distinct pathologic entity. The patients, with a mean age of 60.5 years, presented for evaluation of abdominal pain and a palpable abdominal mass. Four patients were Stage II or IIE, one Stage III, and four Stage IV; eight of nine had B symptoms. Chemotherapy (cyclophosphamide, doxorubicin, vincristine, prednisone, bleomycin [CHOP-B] or cyclophosphamide, doxorubicin, vincristine, methotrexate with leucovorin rescue, cytarabine [ACOMLA]) yielded significant palliation in five patients (mean survival, 12.3 months); three untreated patients and one receiving radiation treatment (XRT) died within 1 month from diagnosis. There was a striking predilection for pleuropulmonary involvement in disseminating disease. The initial blood lymphocyte count correlated significantly with survival (correlation coefficient, 0.84). The one durable complete remission (CR) was obtained in a patient who received substantial surgical debulking before chemotherapy.

Between 1919 and 1981, 16 children with primary cardiac tumors (8 rhabdomyomas, 5 fibromas, 2 myxomas, and 1 rhabdomyosarcoma) and 59 children with secondary tumors of the cardiovascular system were seen at The Hospital for Sick Children in Toronto. Distant metastases in 45 children of the latter group, in descending order of frequency, were from non-Hodgkin's lymphoma, neuroblastoma, soft tissue and bone sarcoma, Wilms' tumor, and hepatoma, and involved the myocardium and pericardium. In the remaining 14 children, tumor thrombi from Wilms' tumor (9 cases), adrenal (2 cases) and hepatocellular carcinoma (2 cases), and endodermal sinus tumor (1 case) extended directly into the great veins and/or cardiac chambers. Children with primary and secondary tumors often present with nonspecific clinical, plain radiographic, electrocardiographic, and M-mode echocardiographic findings. Early recognition, utilizing special diagnostic procedures such as two-dimensional echocardiography, computerized axial tomography, angiocardiography, and inferior venocavography, followed by elective surgical resection of tumor under cardiopulmonary bypass and/or radiation and chemotherapy, offers patients with cardiovascular tumors the best chance of cure.
