Thirty patients with refractory lymphoid malignancies [multiple myeloma (MM): 8, plasma cell leukemia (PCL): 2, acute lymphocytic leukemia (ALL): 5, chronic myelogenous leukemia in blast crisis: 1, chronic lymphocytic leukemia in blast crisis: 1, adult T-cell leukemia: 1, non-Hodgkin lymphoma (NHL): 9, Hodgkin's disease (HD): 3] were treated with VAD regimen (vincristine, doxorubicin, dexamethasone). Of 28 evaluable patients, 4 patients achieved complete response or remission [MM1, ALL1, NHL1, HD1], 10 attained partial response or remission [MM5, PCL1, NHL3, HD1], and 2 patients with MM attained minor response. The remission duration ranged from 1 month to over 14 months. The response rate was high in patients with MM (75%) and lymphoma (60%), however 4 patients with T-cell malignancies achieved no response except one with NHL. In three patients who showed resistance to VAD, diltiazem was administered in addition to VAD and one patient with MM had response. Atrio-ventricular block was also observed in one patient during the period of diltiazem administration. Nine patients developed documented infections, 5 of which suffered from candida infections. From these observations, we concluded that VAD regimen might be useful as a salvage therapy especially in patients with MM and lymphoma.

The molecular events that allow for clonal expansion of the malignant population in chronic myelogenous leukemia (CML) are poorly understood. Recent experiments in transgenic mice suggest a close temporal relationship between expression of the aberrant protein and manifestation of a hematologic neoplasm that resembles CML; tracing the same phenomenon in humans has not been possible. We studied a patient who underwent autologous bone marrow harvest after completion of chemotherapy and radiation therapy for advanced stage Hodgkin's disease. At the time of harvest his peripheral blood counts and bone marrow were morphologically normal. Sixteen months later he developed the clinical manifestations of CML. Detailed molecular evaluation of the harvested marrow showed that a small number of cells contained the Philadelphia chromosome. The time interval required for expansion of the malignant clone, as suggested by this particular patient, was at least 16 months although it is recognized that this figure may be variable.

A new non-T cell, non-B cell lymphoma cell line, designated IN-1, was established from the ascitic fluid of a patient with non-Hodgkin lymphoma. The IN -1 cells did not show any T cell and B cell immunophenotypes. There were rearrangements of T cell receptor beta- and gamma-chain gene, but no rearrangement of T cell receptor delta-chain gene and immunoglobulin JH gene. Electron microscopically, the cell had numerous pseudopods, mitochondria, vesicles, a conspicuous nucleolus, and scattered heterochromatin at the periphery of the nucleus. They reacted with only OKT9 monoclonal antibody. Molecular analysis revealed that cellular DNA from the IN-1 cells did not hybridize with Bam HI W fragment of EB virus DNA. Cytogenetic analysis showed that the chromosome number of the IN-1 was in the range of 61 -63 whose karyotype analysis demonstrated multiple numerical and structural chromosome changes. The IN-1 cells were resistant to etoposide in comparison with an IC50 of K562 (human chronic myelogenous leukemia). Interestingly, this IN-1 cell possessed 85 KD protein, but not P-glycoprotein, both of which are considered to be multidrug resistance-related proteins.

Three anti K562 monoclonal antibodies (MAb) 4.3, 4.6 and 4.8 reacting predominantly with cells of myeloid lineage, were tested for antibody dependent cellular cytotoxicity (ADCC) and complement dependent cytotoxicity (CDC). MAb 4.6 (IgG3k) effectively mediated ADCC against K562 cells and fresh leukemic targets with effectors from healthy donors. However, for ADCC on chronic myeloid leukemia (CML) targets, effectors from CML patients in remission needed modulation with IL-2. All MAb showed significant CDC against peripheral blood (PB) and bone marrow (BM) cells obtained from CML patients in chronic phase, and untreated acute myeloid leukemia (AML) patients. MAb displayed no CDC against PB and BM cells from CML patients in remission and BM cells of Hodgkin's Disease (HD) patients with normal BM cellularity. In clonogenic assay, colony forming units (CFU) in the BM aspirate obtained from CML patients in chronic phase were significantly reduced by treatment with MAb and complement.

Indirect immunofluorescence staining with monoclonal antibody (MoAb) CL203.4 of malignant cells from 269 patients with hematologic malignancies showed a heterogeneous expression of CD54/intercellular adhesion molecule-1 (ICAM-1). This marker was expressed by malignant cells of 57 out of 118 patients with myeloid malignancies and 69 out of 135 with B-lymphoid malignancies. On the other hand, CD54 was not detected on malignant cells of 16 patients with T-lymphoid malignancies. In myeloid malignancies, CD54 is preferentially expressed by "stem cell-derived" malignancies, being detectable on blast cells from almost all patients affected by chronic myelogenous leukemia in blast phase or myelodysplastic syndromes and by only 34% of patients with de novo acute myeloid leukemia (AML). The expression of CD54 did not correlate with any specific myeloid FAB subtype, although three cases of highly undifferentiated AML (FAB MO) displayed maximal levels of the antigen. The expression of CD54 in AML was significantly associated with that of CD34 and HLA-DR antigens. In B-lymphoid malignancies, CD54 expression appears to correlate with the differentiation stage of malignant cells, since B-origin acute lymphoblastic leukemias and conventional B-chronic lymphocytic leukemias (B-CLL; ie, "dim SIg" CLL) expressed lower levels of CD54 than more mature lymphoproliferative disorders ("bright SIg" CLL, prolymphocytic leukemias, and lymphoplasmacytic tumors). "High-grade" B-cell non-Hodgkin's lymphomas (B-NHL) express in general a higher level of CD54 than "low-grade" ones. This finding in conjunction with the expression of CD54 in all 17 patients with "bright SIg" CLL investigated (characterized by marked organomegaly and poor prognosis) suggest that the differential expression of CD54 in lymphoproliferative disorders may also relate to their degree of malignancy.

A patient who developed Philadelphia (Ph) chromosome-positive chronic myelogenous leukemia (CML) 8 years after successful treatment for Hodgkin's disease (HD) is reported. The Ph chromosome with a typical 9(22) translocation was identified by banding techniques in 80% of bone marrow (BM) cells. Southern blot analysis showed breakpoint cluster region (BCR) rearrangement as observed in classical CML. Until now, only three cases of Ph + CML have been reported after treatment for HD. At present, it is not clear whether development of CML after HD represents a therapy-induced complication, an increased susceptibility to secondary malignancies owing to the malignant process itself, a consequence of the immunological deficiencies in HD, or possibly a genetic susceptibility to malignancy.

Recently, several malignant cell types have been reported to express colony-stimulating factor-1 (CSF-1) transcripts; however, the clinical significance of CSF-1 in malignancy has not been investigated. Using a CSF-1 radioimmunoassay, we surveyed concentrations of biologically active CSF-1 in the peripheral blood of 316 patients with malignant and premalignant hematologic disorders; 75 had a myelodysplastic syndrome (MDS), 12 acute myelogenous leukemia (AML), 7 chronic myelogenous leukemia, 21 chronic lymphocytic leukemia (CLL), 106 non-Hodgkin's lymphoma (NHL; of low-, intermediate- and high-grade malignancy), 46 Hodgkin's disease (HD), 46 multiple myeloma (MM), and 3 monoclonal gammopathy of undetermined significance. Controls were 64 healthy subjects. The CSF-1 concentration was correlated with the type of disease, status of the disease, treatment status, and hematologic parameters. CSF-1 concentration was significantly elevated in 83.5% of the patients with active disease, and for each active disease group it was significantly greater (P less than .0001) than in the control. Thus, the high circulating CSF-1 concentration was not associated with a particular malignant phenotype or MDS subtype, but did correlate with the disease activity of both NHL and HD, and the tumor burden in MM, AML, and CLL. There was no correlation of the CSF-1 level with total counts of monocytes or neutrophils in patients with MDS or other malignancies. The cellular basis for the elevated circulating CSF-1 was not investigated. However, the results are consistent with the possibility that the premalignant or malignant cells themselves produce CSF-1 or regulate its production by normal cells.

Autologous bone marrow transplantation (ABMT) has developed considerably in the past 15 years and is now a routine procedure for the consolidation of acute leukemias, non-Hodgkin's lymphomas and Hodgkin's disease. In addition, ABMT has been tested in multiple myeloma (MM) and even considered in highly selected cases of chronic myelocytic leukemia (CML). Interest has resulted from the discovery of new purging procedures such as long-term cultures with or without serum-free media containing various lymphokines, the evaluation of cryoinjury on malignant cells, the increased detection of minimal residual disease using PCR, and the acceleration of hemopoietic recovery post-ABMT through the use of peripheral blood stem cells and/or lymphokines. Results presented include data from the international (ABMTR) and European (EBMT) registries, and our own unit in Paris. With respect to acute leukemias, (a) the EBMT listed 1,688 patients. The overall results were as follows: for patients autografted in complete remission (CR) 1, the leukemia-free survival and relapse rate at 7 years were 48 +/- 2% and 41 +/- 3% for AML and 44 +/- 5% and 45 +/- 5% in acute lymphoblastic leukemia (ALL), respectively. In CR2, the figures were 34 +/- 4% and 54 +/- 5% for AML and 32 +/- 3% and 62 +/- 4% for ALL, respectively. Patients not relapsing at 1 year post-ABMT had a probability of being cured at 7 years of 86 and 71% if autografted in CR1 and CR2 for AML and 81 and 59% for ALL, respectively. Multivariate analysis of relapse rates in several subpopulations confirmed the efficacy of marrow purging in AML CR1: in patients transplanted prior to January 1988 (minimum follow-up of 2 years), the relapse rate with purged marrow was 35 +/- 5% vs. 47 +/- 3% (p less than 0.005). (b) In Paris, St-Antoine, using TBI and marrow purged with mafosfamide at levels individually adjusted (Blood 1986;67:1367), the probability of remission and DFS were 84 and 62% in AML CR1 63 and 59% in ALL CR1, respectively. There was a statistically significant relationship between the relapse rate and the residual amount of CFUGM progenitors in the marrow after purging. The cutoff point was 0.3%, with a relapse rate of 54% in those receiving marrow containing the higher residual CFUGM fractions and only 29% in those receiving less. With respect to non-Hodgkin's lymphomas, the EBMT listed 698 patients. In intermediate or high grade lymphomas, the DFS at 6 years was 30% and 18% in sensitive and resistant relapses, respectively.(ABSTRACT TRUNCATED AT 400 WORDS)

Autologous bone marrow transplantation (BMT) has become effective therapy for high-risk hematologic leukemias with long-term disease-free survivals and apparent cure in a substantial fraction of patients with relapsed aggressive non-Hodgkin's lymphoma, relapsed Hodgkin's disease, and the acute leukemias. Preliminary reports suggest autologous BMT may also be useful treatment for low-grade non-Hodgkin's lymphomas, chronic myelogenous leukemia, and multiple myeloma. Recent studies have begun to address the role autologous BMT should play in these diseases, especially relative to conventional-dose therapy and allogeneic BMT. Relapse remains the major cause for failure following autologous BMT. Novel approaches that can increase the antitumor effect of this treatment without increasing toxicity are being investigated.

The purpose of the study was assessment of the effectiveness of treatment applied in nine proliferative diseases of the haemopoietic system (PDHS) in the years 1951-1980. The effectiveness was determined comparing the mean survival time in each of these diseases in three 10-year-time periods characterised by essential changes in their treatment. Moreover, other factors were studied which may influence the survival time in these diseases. A continuing increase in the survival time correlated with advances in therapy was observed in acute myeloid leukaemia (AML), acute lymphoblastic leukaemia (ALL), Hodgkin's disease (HD) and multiple myeloma (MM). An indicator of the advances in the treatment of acute leukaemias was also an over fourfold rise in the likelihood of achieving complete remission in the decade 1971-1980 in relation to two preceding decades. On the other hand, no improvement of the effectiveness of treatment was noted in chronic myeloid leukaemia (CML), polycythaemia vera (PV), myelofibrosis (MF) and non-Hodgkin lymphomas (NHL). The length of the survival time was influenced also considerably by patient's age (survival lower in old age), sex (better results in women) and place of residence of the patient (worse results in patients living in rural areas).
