A 51-year-old black male with progressive polymyositis presented to our hospital with respiratory failure. Hemodynamic monitoring revealed tachycardia, arterial hypotension, a high cardiac index, and low systemic vascular resistance. Evaluation for common etiologies of this hemodynamic pattern was unrewarding. He was found to have Hodgkin's disease of the bone marrow. Aggressive combination chemotherapy led to normalization of heart rate and arterial pressure. It is postulated that Hodgkin's disease through some undetermined mechanism can cause a hyperdynamic circulatory pattern. This hemodynamic state reversed with suppression of the tumor.

Two hundred thirty-four consecutive cases of malignant lymphoma (192 non-Hodgkin's lymphomas and 42 Hodgkin's disease) from Guangzhou, China, and 589 cases (498 non-Hodgkin's lymphomas and 91 Hodgkin's disease) from the University of Nebraska Lymphoma Registry were examined in a retrospective histopathologic analysis and the results compared to those of the National Cancer Institute (NCI) Working Formulation Summary. Aggressive non-Hodgkin's lymphoma was excessive in Guangzhou (82.3 per cent; P less than 0.001) and Nebraska (80.3 per cent; P less than 0.001) when compared with the NCI data (54.2 per cent). The small noncleaved cell, lymphoblastic, and diffuse mixed-cell subtypes were more frequent in China (15.6 per cent each; P less than 0.001), whereas the small lymphocytic, follicular large cell, and immunoblastic subtypes predominated in Nebraska (8 per cent, 8.4 per cent, and 21.8 per cent, respectively; P less than 0.001). The overall median age of onset for non-Hodgkin's lymphoma was 42.0 years in Guangzhou and 63.5 years in Nebraska. Hodgkin's disease represented 18 per cent of the malignant lymphomas in Guangzhou and 15 per cent in Nebraska. The mixed-cellularity type was most common in Guangzhou (52 per cent; P less than 0.001) and the nodular-sclerosing type in Nebraska (56 per cent; P less than 0.010). The low median age and excess of certain aggressive subtypes of non-Hodgkin's disease in Guangzhou suggest a possible viral etiology, whereas the excess of certain subtypes of non-Hodgkin's lymphoma in Nebraska may be related to intense agricultural activity.

Reports of high-grade non-Hodgkin's lymphoma, Hodgkin's disease, and lymphocytic leukemia in patients with acquired immunodeficiency syndrome (AIDS) or AIDS-like immune disorders have been increasing. In some cases, histologic alterations of lymph node architecture may precede the development of malignant lesions. Early in the course of the disease, clinical profiles of these patients are indistinguishable from those of patients with AIDS-associated opportunistic infections, but rapidly evolving extranodal lesions often signify the establishment of a lymphoproliferative neoplastic process. The frequent involvement of the central nervous system is responsible for the dismal outcome of the disease in a significant number of patients. A high death rate and poor response to antineoplastic agents have often characterized the course of non-Hodgkin's lymphoma and leukemia, but some patients with Hodgkin's disease have had a favorable response to treatment and a long survival. Aggressive multidisciplinary treatment may effectively avert the devastating consequences of this array of lymphoreticular neoplasms. Studies of these intriguing disorders may provide a better understanding of the interrelationships of infection, immunity, and oncogenesis in man.

Non-Hodgkin's lymphomas (NHLs) are a heterogeneous group of disorders that vary widely in response to therapy. In Canada the modified Rappaport classification is used to categorize NHL. To facilitate the reporting and comparison of treatment results all cases should also be categorized in the terminology of the National Cancer Institute's working formulation. The choice of therapy should be guided by specific prognostic factors: stage and bulk of the disease, patient's age, presence of systemic symptoms and histologic subtype. Of these, the last appears to be the most important. Radiotherapy (RT) is the treatment of choice in localized low-grade lymphomas with favourable prognoses, while bimodal therapy (RT and chemotherapy [CT]) is warranted in presentations with unfavourable prognoses. Regional irradiation alone is indicated in intermediate-grade lymphomas with good prognoses (i.e., pathological stage I or II or clinical stage IA or IIA localized disease of small bulk in young patients). All other patients require CT followed by RT. The results of CT alone are encouraging but remain experimental. Aggressive therapy with multidrug regimens that include central nervous system prophylaxis is the foundation for successful treatment of high-grade NHL such as lymphoblastic lymphoma and diffuse small-noncleaved-cell lymphomas. Low-dose RT should be given to sites of bulky disease.

The activity of dCMPase has been measured in cell extracts from human lymphoproliferative disorders. The highest levels occurred in T helper-CLL and Thy-ALL, but high levels were also found in C-ALL, NPDLL transforming to DHL, DPDLL and DHL. A range of enzyme activities was found in the majority of types examined, with the widest range encountered in ALL, NPDLL and DHL. In DWDLL, a narrow range of dCMPase activities was found, with enzyme levels in the control range or moderately increased. Similarly, B-CLL exhibited a narrow range of enzyme activities, within that of the controls. The highest enzyme activity in HD was found in the highly malignant type - lymphocyte depleted HD. Statistically significant differences were found between the distribution of dCMPase activities in ALL and the chronic leukemias; and between favorable histologic types of non Hodgkin's lymphomas and the unfavorable DHL type. These data suggest that dCMPase activity is a marker of the clinical aggression of human lymphoid malignancies. Moreover, the marked variation in enzyme activity in each type of lymphoid malignancy suggests that this also applies to individual tumors as well. In view of the important role of dCMPase in pyrimidine metabolism and the profile of enzyme activities in leukemia and lymphoma, it is suggested that an inhibitor of dCMPase could be of clinical value in lymphoid malignancy.

The incidence of infection in 56 patients with Hodgkin's disease who had undergone staging laparotomy with splenectomy was compared with that of 28 non-splenectomized patients with Hodgkin's disease treated concurrently. The results suggest that splenectomy does not result in a major change in the incidence of infection experienced by such patients with stage II or stage III disease. Aggressive therapy may be of greater importance in increasing the susceptibility to infection in Hodgkin's disease.

Aggressive B-cell lymphomas are clearly related to HIV infection. However, the relationship of HIV infection to low-grade B- or T-cell lymphomas and Hodgkin's disease is not well established. The authors describe a case in which hairy cell leukemia was associated with lupus anticoagulant and direct Coombs' test in an HIV-positive patient.

This study of 52 European patients with Hodgkin's disease (HD) expressing the latent membrane protein 1 (LMP1) oncogene within diagnostic Hodgkin and Reed-Sternberg (HRS) cells was performed to detect LMP1 isolates carrying deletions and to characterize them at a molecular and histologic level. Deletions were identified in 5 cases, clustered near the 3' end of the LMP1 gene, and histologically associated with numerous HRS cells. DNA sequencing showed homology with the deletions seen in the Asian nasopharyngeal carcinoma (NPC) isolates CAO and 1510. Our findings suggest that partial deletions of the LMP1 oncogene, associated with aggressive behavior in NPC CAO and NPC 1510, occur at a particular localization and confer a proliferative phenotype to lymphoid cells in HD.

There were 51 cases of non-Hodgkin's malignant lymphoma (NHL) and 9 cases of reactive follicular hyperplasia among 60 cases of lymphoproliferative conditions. According to the Kiel classification, lymphomas of a low grade of malignancy (17 cases) and lymphomas of a high grade of malignancy (34 cases) were distinguished among NML. Significantly higher activity of the nucleolar organizers (NO) was observed in lymphomas of a high malignancy grade, particularly in lymphomas formed of cells of early differentiation stages, and enhancement of NO activity with development of lymphoma aggression. "Anomalies" of NO activity expression reflecting clinical lymphoma presentation were noted among NML of various malignancy grade. NML with a high NO activity are described as having less favourable prognosis compared to lymphomas with low NO activity. No significant difference in NO activity was found between reactive follicular hyperplasia and follicular centroblast-centrocytic lymphoma. Thus, NO activity can be considered as an additional diagnostic marker of NML grade of malignancy and prognosis.

New techniques such as cytogenetics, molecular biology and immunology have provided new insights into the pathogenesis and development of malignant lymphomas. By this way they provided a new basis for a classification of lymphoid malignancies which is increasingly oriented on biology and pathogenesis. This process resulted in the 'Revised European-American Lymphoma' (R.E.A.L.) classification, which was recently proposed by an international group of pathologists. This classification comprises a preliminary end point of a continuing process which will require a reevaluation and adaptation to new knowledge in the future again. In order to facilitate the clinical use of this histopathologically and biologically oriented classification, a proposal for a clinical grouping was developed, which divides the R.E.A.L. lymphoma subtypes into the following categories: I. Indolent lymphomas (low risk group). II. Aggressive lymphomas (intermediate risk group). III. Very aggressive lymphomas (high risk group). IV. Morbus Hodgkin. This internationally developed consensus of a histopathologic classification and a clinical grouping is a substantial step forward towards an international cooperation in the management of malignant lymphomas. It is background for cooperative studies and justifies the hope that further advances will be achieved in the treatment of malignant lymphomas and that more effective strategies can be developed in the near future.
