The tumours associated to lymphoid leucosis and Marek's disease are compared with lymphoproliferative diseases of man and other species, by morphological, immunomorphological, and aetiological criteria. Morphological and immunomorphological similarities were found to exist between lymphoid leucosis and malignant lymphomas of the B-cell system in man, more particularly, follicular lymphoma, lamphoblastic lymphosarcoma of the B-cell type, Burkitt's lymphoma, and immunoblastic lymphoma. Equivalent similarities with Marek's disease are relating particularly to Hodgkin's disease, infectious mononucleosis, and malignant lymphomas of the T-cell system. Aetiological relations were found to exist between lymphoid leucosis and the oncorna-virus-dependent lymphatic tumours in mammals, while similarities with Marek's disease were relating to infectious mononucleosis, Burkitt's lymphoma, and herpes-virus-dependent lymphatic tumours in monkey. Reference is made to the model nature of both lymphoid leucosis and Marek's disease and the resulting relevance to tumour research.

The indirect immunofluorescent test in fixed P3HR-1 cells showed the sera from patients with lymphogranulomatosis to contain high titers of humoral antibody to the capsid antigen of Epstein-Barr virus. Higher titers of antibody to EBV were associated with unfavourably running histological variants of lymphogranulomatosis. The lymphoid depletion variant was accompanied by high antibody titers to the virus and had a worse prognosis than the nodular-sclerotic variant with lower antibody titers but better prognosis. The level of antibody in lymphogranulomatosis was stable. No relationship between the antibody level and the stage and results of the therapy given was found. In sera from patients with reticulosarcoma and lymphosarcoma no significant rise of antibody titers to EBV was found as compared with a group of normal donors, while in acute leukosis there was a tend for a decline in antibody titers.

The morphology and interactions of lymphoreticular cells in cultures of human tumour tissue was studied by transmission and surface scanning electron microscopy. Macrophages are very common in non-lymphoid neoplasms and vary considerably in shape and surface morphology, with features of mature stimulated cells. Lymphocytes adhere to macrophages more often than to tumour cells. Close contact between macrophages and tumour cells also occurs, but there is no evidence that the infiltrating macrophages or lymphocytes have an overt cytotoxic effect under these cultural conditions. A variety of interactions are seen in cultures of Hodgkin's lymphoma, lymphosarcoma and reticulum cell sarcoma. The only cultural characteristics that may be specific for lymphoma tissue are large intravacuolar collections of lymphocytes within macrophages or giant cells and the rare close spatial relationship between lymphocytes and degenerate macrophages, the latter particularly in Hodgkin's lymphoma. These observations demonstrate the disturbed cellular interrelationships that exist in lymphoma tissue.

Autopsy records are analyzed for 358 patients with reticulum cell sarcoma, lymphocytic lymphosarcoma, or Hodgkin's disease. These records belong to a series of 4,728 autopsy records collected by the Department of Pathology at Roswell Park Memorial Institute from 1957 through 1965. This paper analyzes the distribution of metastases at specific sites in 3 malignant lymphomas. The concept of soil specificity is discussed in connection with the excess of metastases at specific sites. Soil specificity is defined as a higher than expected occurrence of metastases due to a cancer in an organ when compared to other similar primary cancers. In some instances, however, the excess of metastases in a specific site was sometimes also related to the site of origin of a malignant lymphoma. Entire series of organs located either in the abdomen or pelvis showed metastatic patterns which were very likely related to the primary sites of origin. The metastatic patterns of lymphocytic lymphosarcoma and reticulum cell sarcoma appeared to be markedly different from those of Hodgkin's disease. Reticulum cell and lymphocytic lymphosarcomas were not only more widespread than Hodgkin's disease, but the patterns of abdominal and pelvic metastases strongly suggested either their multifocal origin or a different sequence of events in the seeding of lymph node areas, as compared to those of Hodgkin's disease. The relationship between the degree of anaplasia of certain lymphomas and blood-borne metastases is discussed.

Peripheral blood spontaneous rosette forming T cells (RFC) were studied in 40 Hodgkin's Disease (HD) and 20 lymphosarcoma (LS) patients, classified according to the histological type and spread of disease and to their age, treatment, clinical condition and evolution. LS patients had near normal RFC values; in HD, the lowest values of RFC corresponded to the most severe histological picture. In all patients, differences could be seen according to the spread of the disease and the clinical condition, but none in relation with treatment nor with the clinical evolution in a one year period after the test. While in controls and LS patients, RFC were higher in younger than older subjects, in HD, values were higher after 50 years of age. The usefulness of RFC test in the evaluation of lymphoma patients is discussed.

Thirty-four patients with an IgM M-component were evaluated for clinical presentation and course, laboratory data, and histologic findings. An attempt was made to ignore the presence of the IgM M-component and to assign each patient to one of the following categories: Waldenstrom's macroglobulinemia, IgM myeloma, Hodgkin's disease, lymphoma, chronic lymphocytic leukemia, chronic lymphosarcoma cell leukemia, and IgM M-components not associated with an identifiable lymphoproliferative disorder ("benign" M-component). Although transitional forms occasionally occurred, most patients could be readily categorized. The patients with lymphoma, Hodgkin's disease, chronic lymphocytic leukemia, and chronic lymphosarcoma cell leukemia did not appear to behave differently from patients with these disorders who did not have serum IgM M-component. Both for descriptive convenience and for clinical management, continued attempts should be made to separate patients with IgM M-components according to their underlying conditions.

Seven cases of generalised non-Hodgkin's lymphomas (lymphosarcoma, giant follicular lymphoma and reticulum cell sarcoma) were treated by whole-body irradiation as a preliminary study in this centre. Historical background, rationale, treatment technique, and results of such treatment are discussed in this paper. All patients responded, two completely, and five partially. A multicentre clinical trial is recommended to evaluate the results of whole-body irradiation in comparison with chemotherapy in generalised non-Hodgkin's lymphomas.

The karyotypes of cells from 10 Burkitt lymphoma (BL) biopsies, eight cell lines established from BL and nine cell lines from non-BL sources were studied by chromosome banding techniques. With the exception of the BL-derived cell lines BJAB, GC-BJAB, Maku and U-8691 all biopsies and lines of Burkitt origin contained an extra band at the distal region of the long arm of one chromosome 14. An extra band on chromosome 14 was also found in cells of one non-BL biopsy, in cells from a lymphosarcoma-derived cell line and in a long-established cell line derived from the pleural exudate of a patient with Hodgkin's disease. A distal region at the long arm of one chromosome 8 was missing in all metaphase figures of good technical quality in the same material. The size, morphology and stain-ability of the missing region corresponded fairly well to the extra region at chromosome 14. We therefore suggest that the chromosome 14 marker represents a translocation between chromosomes 8 and 14,t (8q-; 14q+). The translocation was present neither in lymphocytes of the peripheral blood of five Burkitt patients nor in five lymphoblastoid cell lines of non-BL origin. Trisomy 7 was found in two of the 10 BL biopsies, in two BL-derived cell lines, in one non-BL biopsy, in two lymphosarcoma-derived cell lines and in one cell line derived from a patient with Hodgkin's disease.

The NBT reduction test and determination of alkaline phosphatase activity in the peripheral blood granulocytes (FAG) were done in 94 subjects including 30 blood donors donating blood for the first time and 64 cases of various haematological syndromes. Raised proportion of formazan granulocytes was found in patients with pancytopenia, acute myeloid leukaemia, chronic myeloid leukaemia during blastic exacerbation, Hodgkin's disease during exacerbation and lymphosarcoma. These results correlated with increased FAG activity. Lower proportions of formazan granulocytes capable of spontaneous reduction of NBT were found in patients with chronic myeloid leukaemia, in immunohaemolytic anaemias and in plasmocytoma. Of all the above syndromes only in chronic myeloid leukaemia impaired ability of formazan cell formation parallelled decreased FAG activity. In the remaining syndromes FAG activity in the granulocytes was normal or raised. In the remissions of Hodgkin's disease a fall was observed in the proportion of formazan granulocytes to values of FAG. In chronic myeloid leukaemia the proportion of formazan cells showed considerable fluctuations and no correlation was observed between the proportion of formazan cells and FAG activity.

The results of an investigation on platelet antibodies by thromboagglutination and antiglobulin consumption test (AGCT) in 51 patients with different types of hemoblastoses (acute and chronic leukemias, Hodgkin disease, lymphosarcoma) are reported. Complete and/or incomplete antibodies were found in 50,9% of the cases, with lymphoid forms showing the highest frequency. Although a constant relation between thrombocytopenia and platelet antibodies is by no means demonstrable, four fully descirbed cases clearly show and the onset of autoimmune thrombocytopenia in the course of hemoblastoses. Two chronic myeloid leukemia cases treated with Myleran and one chronic lymphoid leukemia case presented thrombocytopenic purpura and normal number of megakaryocytes. One case of lymphosarcoma presented thrombocytopenia and autoimmune hemolytic anemia with bone marrow aplasia. Steroid therapy had been partially effective only in two cases. The pathogenetic relationship between platelet immunization and hemoblastoses and cytostatic therapy is discussed.
