A 71-year-old man was admitted because of right cervical lymph node swelling in February 1986. Lymph node biopsy revealed that he suffered from diffuse, large cell malignant lymphoma. Immunological staining showed lymphoma characterized by B cell markers, IgG, kappa type. Bone marrow aspiration, revealed no evidence of lymphoma and 0.2% plasma cells. The clinical stage was IIA. The patient was treated with the CHOP regimen (doxorubicin, cyclophosphamide, vincristine and prednisolone), which achieved complete remission. In October 1988, he was re-admitted because of a subcutaneous abscess, and biopsy of the inguinal lymph node showed reactive lymphadenitis. Although he improved with antibiotic therapy, laboratory date on admission showed monoclonal gammopathy. Serum immunoelectrophoresis demonstrated a monoclonal bow of IgA kappa type, and bone marrow aspiration revealed hypercellularity with an increased number of plasma cells (76.8%). The patient was diagnosed as having multiple myeloma, and combination chemotherapy was begun. He now attends the out-patient department at our hospital. The development of multiple myeloma has not been reported previously during a course of malignant lymphoma. Although the association of these two B cell neoplasias was unknown, in this case both showed the characteristic of kappa type light chains. This case may provide information concerning tumor cell origin.

We report the results of peripheral blood stem cell (PBSC) collection performed after priming with a semi-intensive CHOP regimen in 70 patients with aggressive multiple myeloma (MM). Forty-one of the 44 previously untreated patients compared to 17 of the 26 patients with a refractory disease yielded stem cells enough for autotransplantation. Phenotypic and genotypic studies of collected mononuclear cells, even performed after depletion of monocytes and/or of T lymphocytes, did not reveal contamination by tumor plasma cells or clonal B cell precursors in any studied case. Forty-eight of the 58 patients with successful PBSC collection have been presently treated by high dose therapy followed by autologous blood stem cell transplantation (ABSCT). Among the 43 patients who received a regimen including total body irradiation, four died within six months after the autograft. All remainders responded and most often achieved an impressive tumor mass reduction. Ten relapsed and four died from disease progression. Nine to 70 months (median: 35 months) after blood stem cell collection, 29 patients are either in apparent complete remission or with a state of stable residual disease, most often minimal. Blood stem cell autograft was successful in all evaluable patients and the kinetic of hematologic recovery was roughly related to the amount of reinfused CFU-GM (2.1 to 50 x 10(4)/kg). Median delays for granulocytes greater than 500/mm3 and platelets greater than 25,000/mm3 were 15 days and 20 days, respectively.(ABSTRACT TRUNCATED AT 250 WORDS)

Adriamycin is the most successful anthracycline in malignant lymphomas. Epirubicine is too new to be fully appreciated. Others anthracyclines have no real efficacy in nonleukemic lymphoid malignancies. The prognosis of malignant lymphomas has been transformed since the introduction of this drug in the chemotherapeutic protocols: the level of complete remission increased from 25% with CVP protocols to 50% with CHOP-types protocols, and to more than 70% with intensive chemotherapy protocols (m-BACOD, LNH-80). The number of live patients at 2 years grew in the same proportions. The efficacy of adriamycin in follicular lymphomas is of less value. In Hodgkin's disease the efficacy of adriamycin pull it to first line protocols (ABVD) with identical results to those obtained with MOPP chemotherapy. This drug has its place in the treatment of myeloma patients and in chronic lymphocytic leukemia patients with stage C.

Demethoxydaunorubicin (DMDR), a new anthracycline available both for intravenous and oral administration, was given in 14 cases of leukaemia, non-Hodgkin's lymphoma (NHL) and multiple myeloma (MM) replacing either daunorubicin (DNR) or doxorubicin (DOX) in conventional chemotherapy regimes. In acute leukaemia (6 myeloblastic and 1 common lymphoblastic) there were 5 complete (CR) and 2 partial (PR) remissions; one patient, previously brought into remission with a regime including i.v. DMDR was thereafter maintained in CR with oral DMDR. Among the patients treated with the oral DMDR, 2 NHL cases were treated; 1 patient had a sustained remission of 12 months so far, with DMDR alone; another patient had a CR with a combined regime. In MM, one patient with very advanced disease treated with i.v. DMDR/CHOP did not respond, but three cases treated with oral DMDR plus other drugs showed a partial remission. Toxic effects were limited to brief episodes of nausea and vomiting in a few i.v. treated patients; a prolonged bone marrow depression was observed in one case only. No cardiotoxic effect was recorded.

A 75-year-old female, born in Tochigi Prefecture, was admitted because of lumbago in August of 1991. The leukocyte count was 11,800/microliters with 22.5% atypical lymphocytes. We demonstrated a lymphocyte surface marker, ATL-associated antigen, and proviral DNA. We also identified 2.60 g/dl of serum monoclonal protein, found to be IgG, lambda type, and punched out lesions in the skull. We made a diagnosis of ATL. She was also a HBV carrier. The patient was treated with a modification of CHOP therapy, because of increasing atypical lymphocytes in the peripheral blood in November of 1992. She died of acute hepatitis, suddenly, in March of 1993. Autopsy revealed multiple myeloma, fulminant hepatitis and occult thyroid cancer in addition to ATL.

Nationwide epidemiological studies have disclosed that lymphoid malignancies in Japan are markedly different from those in Western countries; they are less frequent in indolent B-lymphoma and Hodgkin's disease and more frequent in T-cell lymphoma, particularly adult T-cell leukemia-lymphoma (ATL). In 1978, the Lymphoma Study Group (LSG) of Japan started multicenter clinical trials for malignant lymphoma. Since then various kinds of phase II and III studies for aggressive lymphoma, Hodgkin's disease, ATL, T-lymphoblastic lymphoma, acute lymphoblastic leukemia and multiple myeloma have been conducted by the LSG. Based on the results of clinical trials conducted in Western countries and the LSG, the state of the art of chemotherapy for malignant lymphoma is described. In aggressive lymphoma of advanced stages, after establishment of CHOP therapy (1st generation), better results were reported in Western countries for single institute phase II studies of non-cross resistant alternating multiagent chemotherapy (2nd generation) and high relative dose intensity chemotherapy (3rd generation). However, recent multicenter phase III studies, comparing CHOP with 3rd generation regimens, revealed that CHOP remains the best available treatment, because of similar failure-free and overall survival with lower cost and lower severe toxicity.

A 49-year old man was admitted in November 1989, because of anemia, abnormal shadowing on chest X ray and hyperproteinemia. Biclonal gammopathy (IgG kappa + IgA kappa) was shown in serum, and Bence Jones protein in urine. The bone marrow examination showed an increased number of abnormal plasma cells (15.7%) and no evidence of lymphoma, A diagnosis of multiple myeloma (MM) was made. In April 1990, while the patient was treated with the modified M2 regiman, swelling of the right cervical lymph node was observed. Lymph node biopsy revealed that he had non-Hodgkin's Lymphoma (:NHL, diffuse, mixed, B cell type). He was retreated with the CHOP regimen for both disease, but died of respiratory failure in October. 1991. To establish the clonal origin of this case of concominant MM and B-cell NHL, the immunoglobulin gene rearrangements in his lymph node and bone marrow were analyzed. Southern blot analysis with the JH probe and Ck probe showed one common band and one different band in the two samples. Our data suggest that two B-cell malignancies may have arisen from a single B-cell progenitor.

A 56-year-old man was admitted to our hospital in November, 1991 because of hyperproteinemia and anemia. Total protein showed 12 g/dl and serum immunoglobulins were as follows; IgG 974 mg/dl, IgA 142 mg/dl, IgM 9270 mg/dl. M-component was identified as IgM-kappa with immunoelectrophoresis and serum viscosity indicated 6.9. Although the patient had no history of severe streptococcal infection, his serum showed very high activity of ASLO (6890 IU/ml). Bence Jones protein was detected in the urine and determined to be of kappa-type. Plasma cells occupied 43% of bone marrow nucleated cells and their cytoplasms were stained with FITC-labeled anti-IgM and anti-kappa antibodies. X-ray examination disclosed punched out lesions in the skull. Consequently, the patient was diagnosed as having IgM-myeloma. At first, VCAP regimens were given after plasmapheresis, but had no effect. Therefore, the patient was treated with CHOP protocol and the serum IgM decreased in amount and the proportion of bone marrow myeloma cells got down to 17%. ASLO titer also decreased in parallel with IgM. These findings suggest that IgM in this case had ASLO activity.

We retrospectively analyzed factors influencing PBPC mobilization during steady-state hematopoiesis in 52 patients with malignant lymphoma (n=35) or multiple myeloma (n=17) who received 77 cycles of G-CSF (12.5-50 microg G-CSF/kg/day). For 15 of these patients, the first mobilization cycle (12.5 microg G-CSF/kg/day) was followed by a second course with an increased dose of G-CSF (25 or 50 microg/kg/day). Leukapheresis was started on day 4, about 2 h after s.c. G-CSF administration, and repeated on 2-5 consecutive days. CD34+ cells were determined by flow cytometry in each apheresis product and in the peripheral blood prior to G-CSF administration, beginning on day 4. Colony assays were performed on cryopreserved samples prior to autografting. In the 15 patients receiving two mobilization cycles the higher G-CSF dose was associated with higher levels of CD34+ cells, a higher mean yield of CD34+ cells per apheresis (p<0.05), and a higher percentage of successful (>2x10(6) CD34+ cells/kg) collections (p=0.058). Patients with limited previous cytotoxic therapy (n=19, up to six cycles of a standard regimen such as CHOP and/or less than 20% marrow irradiation) who received a daily dose of 12.5 microg G-CSF/kg had higher levels of circulating CD34+ cells, a higher mean yield of CD34+ cells per apheresis (p<0.05), and a higher percentage of successful collections (p<0.05) compared with patients previously treated with more intensive radiochemotherapy (n=15). Ten of 20 patients (50%) who failed during the first cycle were successful during subsequent cycles with escalated doses of G-CSF. Trough levels of circulating CD34+ cells on day 4 were predictive for success or failure to achieve >2x10(6) CD34+ cells/kg, especially in heavily pretreated patients. In conclusion, a daily dose of 12.5 microg G-CSF/kg seems sufficient to mobilize PBPC during steady-state hematopoiesis in the majority of patients who have received limited previous radiochemotherapy. Higher doses of G-CSF, up to 50 microg/kg/day, mobilize more PBPC and should be considered for patients previously treated with intensive radiochemotherapy or those failing to mobilize sufficient numbers of CD34+ cells with lower doses of G-CSF.

We encountered a 65-year-old woman with diffuse large B-cell lymphoma showing t(8;14)(q24;q32) and c-myc gene rearrangement that developed following 12 years of melphalan-based chemotherapy for multiple myeloma. Short-term remission was obtained by CHOP chemotherapy. However, shortly thereafter the patient died of an aggressive progression of lymphoma. It was suspected that the lymphoma was a secondary malignancy related to the treatment with cytotoxic agents and radiation for prolonged multiple myeloma. The chromosomal abnormality t(8;14)(q24;q32) is rare in secondary malignancies. Overexpression of c-myc by gene rearrangement may be associated with clinical courses manifested by the rapid progression of lymphoma.
