We have studied the function of T cells in the peripheral blood obtained from long term survivors with Hodgkin's disease in order to determine the sensitivity of those T cells to normal suppressor cell immunoregulatory mechanisms. Concanavalin A-activated suppressor cells from normal donors suppressed the proliferation of lymphocytes obtained from 11 patients (56.8 +/- 3.5 percent) and from 28 allogeneic normal control subjects (39.8 +/- 2.7 percent [p less than 0.001]). When suppressor monocytes from the normal donors were studied, the mean proliferation of lymphocytes from 19 patients was suppressed 76.3 +/- 4.8 percent whereas proliferation of lymphocytes from 26 normal donors was suppressed 46.6 +/- 4.4 percent (p less than 0.0001). There was no tendency for the increased sensitivity to suppression that was observed in either assay system to return to normal as the patients' disease free interval increased from 1.5 years to 12 years. Furthermore, long-term survivors with diffuse histiocytic lymphoma, who had been treated with comparable chemotherapy, had normal sensitivity to the suppressor monocytes (45.1 +/- 3.8 percent). In Hodgkin's disease, the persistent increased sensitivity of T cells to two different normal immunoregulatory cells suggests that the response of the T cell to regulatory signals may be an important cause of the depressed cellular immunity observed in Hodgkin's disease and a clue to the etiology of the disease.

Three patients presented with liver granulomas and fever. An intensive investigation was initially negative. Corticosteroids were administered with dramatic clinical improvement. Ten months to 3 years later, upon tapering the corticosteroid dose, the initial manifestations reappeared. In two patients Hodgkin's lymphoma was discovered and in a third histiocytic lymphoma. Thus, the diagnosis of lymphoma should be considered in patients with idiopathic liver granulomas, fever, and hepatosplenomegaly without lymph node enlargement, who respond initially to steroid administration but relapse upon tapering the dose.

The incidence of a lymphoreticular system malignancy in patients with chronic lymphocytic leukemia (CLL), Richter's syndrome (RS), is 3.3 to 10.6%. In 89 cases in the literature, the second neoplasm was either reticulum cell sarcoma or large cell diffuse histiocytic lymphoma (DHL), and there were 61 cases of Hodgkin's disease (HD). In a few cases the lymphoma was simultaneously diagnosed, for other cases an association with preexisting CLL was reported. Appearance of lymphoma was associated with leukemia regression for only 4 patients with DHL and 3 with HD. We report one case of B-lymphocyte CLL with macroglobulinemia, treated with melphalan and prednisone, in which DHL developed and the hematologic and histologic signs of CLL and of paraproteinemia remissed. Such patients might constitute a subgroup or a variant of RS. Since the non-Hodgkin malignant lymphomas (NHML) are considered to be monoclonal neoplastic expansion of the B-cell or T-cell lymphocytes, and since in some cases it has been proved that the proliferative cell clone was the same as that of the initial lymphoproliferative disease, RS could be a dedifferentiation or a transformation of CLL, resulting in an aggressive clinical course. The inclusion in this syndrome of CLL cases associated with HD is still controversial. Many of these cases could be giant cell pleomorphic lymphomas, while, on the contrary, in typical cases this association might be merely fortuitous.

Immunologic studies demonstrate that non-Hodgkin's lymphomas are derived predominantly from B- or T-lymphoid cells, while node-based tumors of true histiocytic derivation are rare, with few documented cases. This report describes the clinical, histologic, immunohistochemical, and ultrastructural features of two cases of node-based true histiocytic lymphoma. Distinctive ultrastructural features included numerous cytoplasmic lysosomes, surface microvillous processes, and occasional cell junctions, and the cells stained strongly for alpha-napthyl acetate esterase and alpha one-antitrypsin. Since there are few specific histologic features, special technics may be essential in confirming the diagnosis of true histiocytic lymphoma, and determining appropriate therapy.

Non-Hodgkin's lymphomas of the testis comprise 25-50% of testicular tumors in men over 50 years of age. Using the Rappaport histologic terminology, most testicular lymphomas are of the diffuse histiocytic type. Concomitant involvement of Waldeyer's ring or of paranasal sinuses frequently occurs. Eight patients with primary non-Hodgkin's lymphoma of the testis and 2 patients with a lymphoma which arose in the paranasal sinuses and later involved the testis are reported. The median age of the 10 patients was 57 years. 5 of 8 patients with primary testicular lymphoma were in clinical stage IE. 8 of the 10 patients had diffuse histiocytic lymphoma. Using the Kiel histologic terminology, 4 of these 8 patients had diffuse centroblastic lymphoma and 4 had immunoblastic sarcoma. 5 of the 8 patients with primary testicular lymphoma had complete remission after orchiectomy followed by radio- and/or chemotherapy. The median survival of the 8 patients with primary testicular lymphoma was 30 months. The median survival of patients with complete remission was 44 months and in patients without remission 12 months. Careful staging of patients with testicular lymphoma is of decisive therapeutic and prognostic significance.

The numbers of alpha-naphthyl acetate esterase (ANAE)-positive cells (other than T cells) have been counted in 32 specimens of Hodgkin's disease and two specimens of histiocytic lymphoma. The different Rye subtypes of Hodgkin's disease contain varying numbers of enzyme-positive cells, ranging from 1.8-16% in the lymphocyte-predominant form to 39.8-47% in lymphocyte-depleted Hodgkin's disease. The percentage of enzyme-positive cells in the mixed cellularity variety was from only 6.5 to 14.6%. In the two specimens of apparently genuine histiocytic lymphoma, the enzyme-positive cells constituted 95.2 and 97.5% respectively of all cells. Thus, the numbers of macrophages and macrophage-like cells in true histiocytic lymphoma are much greater than in Hodgkin's disease.

One hundred and twenty-three patients with advanced measureable malignant lymphomas resistant to conventional chemotherapy were entered in a prospectively randomized trial of two teniposide (VM-26)-based combination chemotherapy regimens: V-PLAT (VM-26, cisplatin, and prednisone) and V-HEX (VM-26, hexamethylmelamine, and prednisone). Ninety-seven eligible and evaluable patients received protocol therapy. Sixteen percent of the patients had Hodgkin's disease, and 84% had non-Hodgkin's lymphoma. All patients were ambulatory (Eastern Cooperative Oncology Group Performance status 0, 1, or 2), 70% had stage IV disease, 59% had "B" symptoms, and all had failed either two or three previous chemotherapy regimens. Toxicity was mainly hematologic and significantly greater with V-PLAT. Objective tumor responses were seen in nine of 45 patients (20%) treated with V-PLAT (duration, 4-35 + weeks) and in four of 51 patients (8%) treated with V-HEX (duration, 10-65 + weeks). Among the 12 patients with histologically confirmed histiocytic lymphoma treated with V-PLAT, five (42%) experienced objective tumor responses, including two complete responses. Overall median survival was approximately 6 months, with no difference between treatment regimens. Limited antitumor activity of these combination regimens in patients with advanced malignant lymphomas has been demonstrated. However, the objective response rates were not higher than we have previously seen with either VM-26 (22%) or hexamethylmelamine (27%) given in maximum tolerable doses as single agents.

An increased excretion of modified nucleosides has been observed in patients with malignant lymphomas. Using high performance liquid chromatography, we have determined the concentration of pseudouridine in the urine from 48 patients with malignant lymphomas. Elevated excretion of pseudouridine was observed in 50% of patients with histiocytic lymphoma, compared to 33% for patients with lymphocytic lymphoma and 13% for Hodgkin's lymphoma. When the patients were subdivided into clinical stages according to disease manifestation, no correlation could be found between level of excretion and the clinical stage. To estimate the prognostic relevance of pseudouridine excretion before treatment, we compared the levels from patients that were deceased due to lymphoma, with those living free from disease. The median observation time for the patients was 27 months. No prognostic value could be attributed to the initial excretion of pseudouridine.

We have confirmed our previously described finding that the group-5a antigen is associated with acute lymphoblastic leukemia. In addition we have found that the 5a antigen has an increased frequency in patients with chronic lymphocytic lymphoma but not in patients with acute myelogenous leukemia, acute myelomonocytic leukemia. Hodgkin's disease or histiocytic lymphoma.

Among 87 cases of different non-Hodgkin lymphomas studied with morphologic, enzymehistochemical, and immunologic techniques, ten were found with a positive alkaline phosphatase staining reaction of the cell membranes. The ages of the seven adult patients included in this report varied between 48-85 years. Studies of cell suspensions or cryostat sections demonstrated the presence of monoclonal membrane immunoglobulins indicating a B-cell origin of these lymphomas. Investigation of peripheral blood of six patients revealed the presence of a corresponding monoclonal lymphocyte population in four. According to Rappaport's classification, lymphoblastic, poorly differentiated, and well-differentiated lymphocytic as well as histiocytic lymphoma were encountered. According to the "Kiel" classification, most lymphomas were classified in the group of follicle-center cell tumors. The clinical course of the patients was variable. Non-Hodgkin lymphomas with alkaline phosphatase positive staining do not constitute a separate entity.
