Treatment of acute lymphoblastic leukemia in adults.

Thirty-seven adult patients with acute lymphoblastic leukemia were treated with a protocol called HEAV'D including Adriamycin, Vincristine, L-Asparaginase, Cyclophosphamide and Dexamethasone. The complete remission rate was 70 per cent. The median duration of remission was more than 30 months. Patients with initial leukocyte count below 20 000/mmc experienced a longer remission (median not reached) than patients with a leukocyte count above 20 000/mmc (median 10 months).

Mitoxantrone alone or in combination chemotherapy (VeMP) as second-line treatment in relapsed or refractory poor-prognosis non-Hodgkin's lymphoma. A report of the Non-Hodgkin's Lymphoma Co-operative Study Group (NHLCSG).

BACKGROUND AND METHODS: From October, 1986 to July 1989, 35 consecutive patients with high- and intermediate-grade non-Hodgkin's lymphoma, relapsed or refractory to first-line-anthracycline-containing regimens, were treated with mitoxantrone alone or in combination chemotherapy (VeMP: Ve = VP-16, M = Mitoxantrone, P = Prednisolone). RESULTS: In the first 15 patients, treated with Mitoxantrone alone, complete response (CR) and partial response (PR) each occurred in 4 patients, for a total response rate of 54%. In the following 20 patients, treated with the VeMP regimen, CR occurred in 10 patients (50%), PR in 1. The overall three-year survival was 27% in the first group and 40% in the second. Acute toxicity was generally mild. No patient developed cardiac symptoms or other toxicities requiring discontinuation of therapy. Myelosuppression was the most important side effect, being more remarkable for patients treated with VeMP regimen. CONCLUSION: Mitoxantrone, alone or in combination chemotherapy, appears to be a drug with significant activity in aggressive non-Hodgkin's lymphomas.

Hairy cell leukemia. A therapeutical update.

This is a review of current treatment for hairy cell leukemia (HCL). Data for this analysis were obtained from the Italian HCL Registry, as well as from other published series. We have given space to the impact of interferon and pentostatin on the management of this disease. Other issues are also discussed, such as the relevance of achieving a complete remission with respect to overall and relapse-free survival. We include a final section on recommendations which may prove useful in designing an appropriate therapeutic strategy.

The effect of thymic substances on T circulating cells of patients treated for Hodgkin's disease.

Forty-one patients with Hodgkin's disease staged as IA(4), IIA/B(4/6) IIIA/B(6/9) and IVA/B(3/9) who had had radiotherapy (subtotal nodal irradiation (STNI) or total nodal irradiation (TNI), or combined one (STNI/TNI plus chemotherapy MOPP or MOPP/ABVD) have been enrolled consequently and randomized to receive thymic hormone (17 patients) or pentapeptide treatment (14 patients) for 3-6 months at the end of the therapeutic regimens. In all patients severe immunodeficiency evaluated either as leukopenia (WBC less than 4000/mm3) or lymphocytopenia (lymphocytes less than 1500/mm3) or CD3 and CD2 cell reduction, or imbalance of helper/suppressor (H/S) ratio have been documented before starting thymic therapy. Different results by immunorestorative therapy have been registered according to the entity of immunodeficiency. In fact in the group of 15 patients with severe lymphopenia (lymphocytes less than 1000/mm3) either the thymic hormone or the synthetic drug produced a significant increase of all subsets examined: CD3-CD2-CD4-CD8 without or with minimal influence on H/S ratio, due to the increase of absolute lymphocytes count. In the remaining patients with mild or no lymphopenia the two drugs resulted ineffective on T cells. Comparing the overall group of patients who received thymic therapy with a control group of patients who did not, an advantage in terms of recruitment of T cell compartment has been observed in the former group when mean values are compared. According to the clinical impact of the immunotherapy with thymic substances on these patients, a significant decrease in incidence of herpes virus infection (HVI) has been observed in patients who had had thymic therapy compared with the incidence of HVI in the control group (18% versus 53.8%).(ABSTRACT TRUNCATED AT 250 WORDS)

Immunobeads test (antibody coated polyacrylamide beads) in the immunological characterization of lymphoproliferative disorders.

Three groups of patients with immunoproliferative disorders (15 multiple myeloma, 11 non-Hodgkin's lymphoma, 21 chronic lymphocytic leukemia) were studied by immunological characterization and compared to a group of 20 normal subjects (controls) using anti-immunoglobulin coated polyacrylamide beads (T-B Quantigen test, QT), erythrocyte rosettes (ER), surface immunoglobulin (SIg), and monoclonal antibodies for T and B cells (OKT3; OKT11; OKT8; OKT4; IaDR); null cells (NC) and double marker (DM) cells were also considered. The values for normal subjects for T-B, NC and DM cells were comparable. Results for the patient groups strikingly differed. There were progressively larger differences between the T and B percentages obtained with different techniques. The largest differences were seen in patients with chronic lymphocytic leukemia and the smallest in multiple myeloma patients; values were intermediate in non-Hodgkin lymphoma. The different findings were related to the number of DM cells (ER+, SIg+ QT+) and the different tests used. The importance of these findings in the diagnostic approach to lymphoproliferative disorders is discussed.
