We reported the experience of peripheral blood stem cell transplantation (PBSCT) performed in adult patients with hematological malignancies and solid tumors. After myelosuppressive chemotherapy, peripheral blood stem cells were collected using a Blood Cell Separator (CS-3000) during bone marrow recovery and subsequently cryopreserved in 17 patients (9: malignant lymphoma; 2: ALL; 2: AML; 2: multiple myeloma; 2: solid tumors). In 28 apheresis cases, the collected number of granulocyte/macrophage progenitors (CFU-GM) was more than 5 x 10(5)/kg BW in 17 apheresis cases and ranged between 2 and 5 x 10(5)/kg BW in 4 of such cases. Eleven patients (7: malignant lymphoma; 1: ALL; 1: AML; 1: multiple myeloma; 1: neuroblastoma) underwent PBSCT following myeloablative chemotherapy. The infused number of CFU-GM ranged between 0.6 and 18.1 x 10(5)/kg BW. In 7 patients, more than 5 x 10(5) CFU-GM/kg BW were infused. The median time to reach 500 neutrophils/microliter or 50,000 platelets/microliter was 10 (range: 8-17) and 20 (range: 8-63) days, respectively. One patient died from sepsis before hematologic recovery occurred. Eight patients are alive with no evidence of active disease for 7-19 months after PBSCT. When the infused number of CFU-GM is more than 2 x 10(5)/kg BW, PBSCT following myeloablative chemotherapy seems to be safe and useful treatment.

Using the envelope method, we allocated 125 patients with infections accompanied by hematopoietic disorders into two groups treated with imipenem/cilastatin sodium (IPM/CS) at a daily dose of 1 g/1 g b.i.d. (group BID) or 0.5 g/0.5 g q.i.d. (group QID), and obtained the following results. 1. In group BID, ANLL was observed in 25 patients; ALL in 6; and NHL in 12. In group QID, ANLL was observed in 27 patients; ALL in 7; and NHL in 13. 2. In group BID, efficacy rates were 54.5% (6/11) in sepsis, 63.0% (17/27) in fever of undetermined origin and 50.0% (4/8) in pneumonia, thus the overall efficacy was 61.8% (34/55). In group QID, efficacy rates were 66.7% (4/6) in sepsis, 76.0% (19/25) in fever of undetermined origin and 35.7% (5/14) in pneumonia, thus the over all was 61.1% (33/54). No significant difference in response rates were observed between the two groups. 3. Bacteriologically, 22 bacterial strains were isolated in group BID and 21 21 strains, in group QID. The eradication rates after treatment with IPM/CS was 100% in group BID and 66.7% in group QID. 4. Side effects were observed in 8 patients in group BID and 3 in group QID. Laboratory examination revealed abnormal values in 9 patients in group BID and 6 in group QID. However, all of the side effects disappeared after the suspension or discontinuation of IPM/CS. The efficacies of IPM/CS therapy for severe infections in patients with hematopoietic disease were similar between 1 g/1 g b.i.d. and 0.5 g/0.5 g q.i.d. groups.

From July 1987 to July 1991, 12 children underwent AMBT following high-dose cytarabine (HD Ara-C) plus 14.4 Gy hyperfractionated total body irradiation (hyfr-TBI) for early isolated extramedullary relapse of ALL, while in first BM remission. No patient received intrathecal prophylaxis following AMBT. One patient died on day +5 due to sepsis and three patients, two of them transplanted in second and third CNS relapse, respectively, died from BM relapse occurring 1.5, 4 and 5 months after AMBT. Eight of the 12 survive disease-free with a median follow-up of 24 months (range 14-62 months). The toxicity of HD Ara-C plus hyfr-TBI was acceptable and well controlled with supportive therapy. These results suggest that ABMT following HD Ara-C plus hyfr-TBI may eradicate leukemia from extramedullary sites of ALL relapse.

Cytogenetic follow-up studies such as those reported after allogeneic bone marrow transplantation are not available in patients submitted to an autologous bone marrow transplantation (ABMT). Of 114 patients with acute leukemia (69 acute myelocytic AML, 43 acute lymphocytic ALL, 2 undifferentiated) who underwent an ABMT in our institution in the period from February 1983 to December 1989, 66 had evaluable cytogenetic data post-transplant. They all received a pretransplant regimen consisting of cyclophosphamide (CY) and total body irradiation (TBI) followed by reinfusion of marrow purged with mafosfamide. Twenty patients showed chromosomal damage at some time; of these, six relapsed early post-ABMT, one died while in persisting remission at 81 months post-ABMT from overwhelming pneumococcal sepsis related to a previous splenectomy, and 13 are still alive and well at 13 to 88 months post-transplant. The bone marrow cytogenetic abnormalities were complex: they included various numbers of clonal aberrations or variations or combination of those; they affected all but the Y chromosome, with a predominance however for chromosomes 1, 3, 6, and 7; they were often transitory and in some instances became modified with time. None of these chromosomal abnormalities was connected with the initial leukemia, even in the 6 patients who relapsed early. In the other 14 patients, these abnormalities have so far had no detectable unfavourable implication. The origin of these abnormalities is unknown: both the pretransplant regimen (CY and/or TBI) and/or marrow purging with mafosfamide can be incriminated. Additional studies in patients autografted with pretransplant regimen not containing TBI and/or with unpurged marrow are necessary to discriminate between these two possibilities.

We present a patient who underwent sibling allogeneic BMT because of refractory Ph+ve ALL and remained BCR-ABL-positive after marrow grafting. Haemopoietic precursor cells were predominantly BCR-ABL-negative and of donor origin. In T cells an exclusively donor genotype was demonstrated. Despite donor leucocyte infusion (DLI), 20 weeks after BMT BCR-ABL fusion mRNA increased in semiquantitative polymerase chain reaction and leukaemic infiltration of the patient's bone marrow was seen. After a second course of DLI the patient achieved sustained molecular remission but he developed severe graft-versus-host disease (GvHD) and died from bacterial sepsis 9 months after DLI.

We examined in vivo spontaneous and prednisolone-induced apoptosis in peripheral blood samples of 23 children with ALL by flow cytometric and morphologic methods. There was no significant spontaneous apoptosis before the therapy. Six hours after prednisolone therapy, increased apoptosis was found in 19 of 23 cases. In one case, the apoptosis of blast cells could not be compared with the clinical data, because the patient died in sepsis during the induction therapy. In 18 of 22 evaluable cases, the in vivo apoptosis correlated with the decrease of leukemic blasts during the first 8 days of prednisolone monotherapy. In 20 of 22 children, a correlation was found between in vivo prednisolone-induced apoptosis and clinical outcome. The p53 gene expression was elevated in 2 of 10 patients. No elevation in the expression of bcl-2 gene was observed. In 6 of 23 cases, the glucocorticoid receptors were measured. The correlation of clinical responsiveness and gcR mRNA shows less parallelism than does the apoptosis correlation.

We sought to determine the role of granulocyte colony-stimulating factor (G-CSF) as an adjunct therapy in high-dose cytarabine-containing chemotherapy (HD C/T) for children with acute leukemia. Seventeen patients, aged 9 months to 18 years old, 8 ALL and 9 AML, were treated with cytarabine (Ara-C) 1 g/m2 q12h for 8 doses with mitoxantrone, idarubicin, VP-16, or asparaginase. A total of 71 courses of HD C/T was given. G-CSF was not used in 14 courses (Group A). Prophylactic G-CSF was given in 57 courses (Group B) as 200 microg/m2/d SC started one day after the completion of HD C/T and continued until the neutrophil recovery was maintained. The incidences of sepsis per course in Group A and Group B were 35.7% (5/14) and 40.4% (23/57), respectively. While 2 patients in Group A died of sepsis or pneumonia, none in Group B died. The mortality and delay in chemotherapy were fewer in Group B (P = 0.037 and 0.0006, respectively, Fisher exact test). There was a shorter average number of days of neutrophil <500/cumm, antibiotic usage, fever, and hospital stay in Group B (11, 8, 5, 17 days in Group B vs. 21, 17, 10, 37 days in Group A; P = 0.0001, log-rank test; 0.0006, 0.0023, 0.0001, Wilcoxon rank sum test, respectively). The incidence of neutropenic fever was lower in Group B, but the difference did not reach statistical significance (P = 0.06, Fisher exact test). We conclude that G-CSF as an adjunct therapy in HD C/T is effective in reducing mortality, days of neutropenia, antibiotic usage, fever, hospital stay, and frequency of delay in chemotherapy. The efficacy of this treatment approach requires further testing in a randomized, controlled trial.

36 patients with relapsed (29) or refractory (7) acute lymphoblastic or nonlymphoblastic leukaemia received regimens employing 1-3 courses of mitoxantrone (or idarubicin), intermediate doses of cytarabine and etoposide. Complete remission (CR) was achieved in 30% of patients (5/15 ALL, 6/21 AML, 5 cases of refractory and 6 of relapsed leukaemia). Duration of CR was 3-6+ months (3 patients are still alive). Toxicity of the treatment was acceptable, however 5 patients with severe granulocytopenia died from sepsis.

Aiming to target the minimal residual disease in patients with multiple myeloma, a phase I/II single centre study was undertaken for feasibility and tolerance of intensive acute lymphoblastic leukaemia consolidation chemotherapy (ALL-IC) as part of a strategy for post-transplant consolidation targeted at pre-B cells. Seventeen newly diagnosed patients with myeloma (median age 55 years; 30-65) were initially treated with courses of infused cyclophosphamide, vincristine, adriamycin and methylprednisolone (C-VAMP) followed by melphalan 200 mg/m2(HDM) and peripheral blood stem cell rescue (PBSC). Forty-seven percent were in CR and the rest in PR after HDM. ALL-IC consisted of vincristine, daunorubicin, etoposide, cytarabine, 6-thioguanine and prednisolone given over 5 days. All patients became neutropenic (<0.5 x 109/l) at a median of 10 days (4-18) and one of the 17 patients (5.8%) died 15 days post ALL-IC of sepsis. A further four have died of relapse with an overall survival (OS) of 67% at 4 years. Two of nine patients in PR at the time of ALL-IC achieved CR. Matched-pair analysis of 34 control patients shows no difference for OS and event-free survival between ALL-IC and controls. We conclude that ALL-IC given to myeloma patients after HDM/PBSC is as safe as when used in ALL and warrants further assessment in randomised trials for myeloma.

Mycobacterium tuberculosis is a serious, but rare infectious complication after allogeneic bone marrow transplantation. We describe a case of fatal sepsis due to Mycobacterium tuberculosis after allogeneic bone marrow transplantation for Philadelphia chromosome-positive ALL. The diagnosis was made after BAL. Although broad-spectrum antituberculous therapy was started immediately after diagnosis, blood cultures became positive for Mycobacterium tuberculosis. The patient developed severe pyrexias and finally died of multi-organ failure. Rapid progression of mycobacterial infection should be considered in patients post BMT with unexplained fever, particularly in patients from endemic areas.
