The reactivity of peripheral blood lymphocytes from patients with advanced malignancy was assessed by mitogen-induced stimulation of protein synthesis as measured by 3H-leucine incorporation. It was confirmed that the lymphocyte response of patients was depressed. Furthermore, the lymphocytes of 15 out of 27 cancer patients, selected because of their low responses, inhibited the reactivity of normal lymphocytes in co-cultures. The lymphocytes from one patient with Hodgkin's disease were also inhibitory. In contrast, lymphocytes from healthy subjects, patients with chronic lymphocytic leukaemia, lymphosarcoma or multiple myeloma caused no suppression. Experiments with purified cell populations from patients with carcinoma indicated that purified T cells responded to mitogens while unseparated lymphocytes failed to respond and that the inhibitory activity was due to adherent cells, presumably monocytes. There was no evidence for B-cell-mediated suppression. However, in two cases inhibition was caused by isolated T cells of the patients and not by adherent cells. These experiments suggested that one mechanism for the depression of cell-mediated immunity seen in patients with advanced cancer may be the nonspecific suppresssion of certain T-cell functions by circulating monocytes.

A patient who developed an immunoblastic leukemia of T-cell type two and one half years after initial diagnosis of mixed cellularity Hodgkin's disease, stage IIIB, is described. The patient's course was characterized by an initial 15-months remission following radiation therapy. A relapse of Hodgkin's disease was treated with intensive chemotherapy. Thirteen months later the patient entered a rapid terminal course with multiple organ infiltrates and a leukemic peripheral blood. The leukemic phase was characterized by a 55,000 WGC with 48% immunoblasts, greater than 90% of which marked as T-cells. Although acute myelogenous leukemia, acute lymphocytic leukemia, lymphosarcoma cell leukemia and other tumors have been described in Hodgkin's disease after intensive therapy, this is the first report of the unusual association of a T-cell immunoblastic leukemia with Hodgkin's disease.

Human lymphocytes from peripheral blood, bone marrow spleen and lymph nodes were cultured. Continuous phytoheamagglutinin (PHA) stimulation was used, first during a 24 h liquid preincubation, then during a 5 day culture in methylcellulose. In normal donors a rapid colony formation took place, with a mean of 124+/-82 colonies per 1 times 10(5) preincubated lymphocytes. Cells from such colonies were studied by cytology, scanning electron microscopy and rosette formation techniques; arguments favour the hypothesis that these could be T lymphocytes. Neither granulocytes nor macrophages could be grown, and no lymphoid colony formation occurred without PHA stimulation. The same technique was applied to patients with various lymphoproliferative disorders. Significant colony suppression was observed in nearly every case of chronic lymphatic leukaemia; the number of colonies was reduced in some patients with acute lymphatic leukaemia, lymphosarcoma, dysglobulinaemia and Hodgkin's disease. This lymphoid culture method should be applied to a larger number of patients to determine whether it has a classification value and/or prognostic significance. When colonies were grown in pathological states, rosette formation was identical to that of normal donors; colony formation could be due to persisting normal lymphocytes.

Cytochemical identification of T lymphocytes on the basis of alpha-naphthyl acetate esterase (NAE) activity was compared with immunologic markers for cell suspensions and/or cryostat sections of 113 specimens. Nonneoplastic tissues (peripheral blood, lymph nodes, spleens, tonsils, thymus, and pleural fluid) and specimens from various lymphoproliferative disorders, including acute and chronic lymphocytic leukemia, lymphosarcoma cell leukemia, hairy cell leukemia, non-Hodgkin's lymphomas of B-and T-cell types, and Hodgkin's disease, were evaluated. T (E-rosetting) cells demonstrated several patterns of NAE reactivity: 1) a strong globular reaction product, the most specific pattern for T-cell identification, 2) granular cytoplasmic staining, or 3) no reactivity. B lymphocytes revealed a granular pattern of NAE staining, were devoid of enzyme, or, in rare instances, exhibited strong NAE activity. Percentages of lymphoid cells with strong (globular) NAE activity closely paralleled T-cell (E-rosette) values in the majority of cases, with the best correlations observed for peripheral blood studies. However, discordant results were noted for some neoplastic and nonneoplastic tissues, including cases of T-cell lymphoma or leukemia. Markedly discrepant results were noted for thymic lymphocytes, most of which revealed E-rosette formation and weak or absent NAE activity. Lymph nodes involved by Hodgkin's disease demonstrated a heterogeneous pattern of staining in E-rosetting cells and in Reed-Sternberg variants. Cryostat section studies of reactive lymph nodes and nodular lymphomas demonstrated strong NAE staining in lymphoid cells of T-cell (interfollicular, internodular) areas, with little or no positivity in follicles or nodules (B-cell areas). NAE staining patterns further suggested that T cells comprise part of the follicular cuff and possibly represent a minor population of some neoplastic nodules. Although NAE determinations do not represent a consistently reliable alternative to immunologic methods for T-cell identification, this easily applicable cytochemical marker is complementary to other techniques in assessing neoplastic or nonneoplastic tissues, particularly cryostat sections. (Am J Pathol 97:17--42, 1979).

Out of a total number of 123 patients with non-Hodgkin lymphomas the result of local radiation therapy from 65 patients with lymphosarcomas or reticulosarcomas stage I or II are reported. In stage I, the tumor still being localized, there are good chances for recovery (3 or 4 years of survival without recurrenced in 75%). Already in stage II the percentages of a three-year survival without recurrences are reduced to 40% with lymphosarcomas and to 19% with recitulosarcomas. This most probably is due to an early, occult, already advanced cancerous spread, not having been recognized. More aggressive diagnostic measures for the staging, therefore, are recommandable. There are significant differences between lymphosarcomas and recitulosarcomas concerning their mode of propagation. Lymphosarcomas prefer the propagation into contiguous lymph node stations. With reticulosarcomas the generalisation to stage IV predominates at the first recurrence. For an improvement of the therapeutic results an irradiation is recommended which encompasses the adjacent lymphatics not yet being involved, the so-called "extended field technic". Early cytostatic therapy in stage II additionally has to be discussed, particularly for reticulosarcomas.

Blood lymphocyte DNA synthesis, as expressed by 24-h uptake of 3H-thymidine in culture of mononuclear peripheral blood leucocytes has been reduced prior to treatment in 18 patients with Hodgkin's disease, 11 with non-leukaemic lymphosarcoma, 13 with reticulosarcoma and 20 with various solid tumors, and compared to 37 normal control subjects.The 3H-thymidine uptake was significantly increased in all the patient groups, but no significant difference existed between them. Increased uptake of 3H-thymidine did not appear to correlate with the degree of dissemination in any of the patient groups or with the presence or absence of general symptoms in malignant lymphoma. It is concluded that increased DNA synthesis in peripheral blood lymphocytes is a feature not limited to Hodgkin's disease, but found in non-Hodgkin's malignant lymphomas and other malignancies to about the same extent.

The clinical and pathological findings in 46 patients with cryptococcosis at Memorial Sloan-Kettering Cancer Center from 1956 to 1972 are reported. The striking predilection for cryptococcal infection in patients with leukemias and lymphomas is again confirmed. Of 41 patients with neoplastic disease, those with chronic lymphatic leukemia (CLL), Hodgkin's Disease, chronic myelogenous leukemia (CML), myeloma and lymphosarcoma had the highest incidence of cryptococcosis. In all cases, neoplastic disease was widespread when infection occurred. All of these patients had leukopenia and absolute lymphopenia at the time of infection. Thirty-nine were on steroids. Thirty-one patients with neoplastic disease had disseminated infection. Review of pathology revealed a spectrum of inflammatory lesions. Histiocytic-lymphocytic infiltrates occurred in the central nervous system in 10 patients. In six cases, reaction was granulomatous. There were single instances of suppurative and fibrotic reactions. Mortality from infection was high in patients with neoplastic disease. Twenty-four of 28 deaths occurred within 60 days as a result of infection. Within one year, 10 more patients died, nine of cryptococcosis. Only three survived more than one year, and all patients died within 600 days. Twenty-nine patients with neoplastic disease received amphotericin B. Only nine survived more than 60 days.

In 2.9% of 1762 patients with pleura exudate, the underlying disease was a lymphoreticular sarcoma. The experienced cytologist has no difficulties to differentiate typical patterns of plasmocytoma, reticulumcell sarcoma or lymphogranulomatosis. But there may be borderline forms which can only be evaluated by critical examination. This holds true especially for differentiated types of lymphosarcoma which resemble the pattern of lymphocytic leukemia or observed through low magnification look like lymphocytic exudate. Therefore the use of oil immersion is necessary for evaluation of the smear. Fluorescence microscopy offers some advantages in special problems.

64 patients with extensive non-Hodgkin lymphomas were treated with a modified MOPP scheme. 41 patients had stage IV disease. 59 patients responded to treatment. In 22 cases complete remission was obtained and in 37 cases partial remission. The proportion of complete remissions was the same for reticulosarcoma (9 out of 28) and lymphosarcoma (7 out of 22). The remission rate for Brill-Symmers disease was higher (6 out of 14). For patients with lymphosarcoma the average duration of complete remission was 26.9 months and for patients with reticulosarcoma 25 months. 42 of the 59 patients who responded to treatment survived one year, 33 of them two or more years. After a two-year period there were no more deaths.

A literature review about the significance and incidence of lymphography in intrathoracic diseases (lymphogranulomatosis, reticulum cell sarcoma, lymphosarcoma, chronic lymphatic leukemia, giant follicular lymphoma, pulmonary sarcoidosis) is given. Intrathoracic manifestations of malignant lymphomas are absolute indications for lymphography. With the proof of retroperitoneal lymph node involvement alterations in staging of the disease and therapeutical consequences are emerging. In benign lymph node diseases, such as pulmonary sarcoidosis, lymphography will be also helpful for staging, but therapeutic consequences do not ensue, an absolute indication for lymphography is not validated. Lymphography is valuable for the diagnosis of diseases and injuries of the thoracic duct. The existing methods of lymphographic visualization of intrathoracic lymph nodes are not yet satisfying and need further research.
