Emerging evidence suggests that stem cells and progenitor cells derived from bone marrow can be used to improve cardiac function in patients after acute myocardial infarction. In this randomised trial, we aimed to assess whether intracoronary transfer of autologous bone-marrow cells could improve global left-ventricular ejection fraction (LVEF) at 6 months' follow-up.

The AF1q gene, a mixed-lineage leukemia fusion partner, is highly expressed in hematopoietic progenitor cells but has low expression in differentiated cells. We determined the expression of the AF1q gene by reverse transcriptase-polymerase chain reaction in 64 pediatric acute myeloid leukemia (AML) patients treated on Children's Cancer Group clinical trial CCG-2891 and correlated its expression level to clinical characteristics and outcome. AF1q expression in patients varied from 0- to 154-fold compared with normal marrow, and increasing expression level was associated with worsening survival, with a hazard ratio of 1.02 per fold increase in AF1q expression (P = .032). We divided patients into tertile groups based on AF1q expression level. Patients with high AF1q expression (top tertile) had a higher predominance of French-American-British M1 compared to patients with lower 2 tertiles of AF1q expression (43% vs 9%, P = .003). High AF1q expression was associated with poor survival in univariate and multivariate models. Overall survival at 8 years for patients with the high AF1q expression was 19% versus 50% in patients with low AF1q expression, (P = .01). AF1q expression may correlate with clinical outcome in pediatric AML, although it is not clear if AF1q is simply a marker of a more primitive phenotype or contributes directly to leukemogenesis.

A total of 61 patients with haematological malignancies were randomised either to allogeneic transplantation with blood stem cells (BSC) or bone marrow (BM), of whom 37 patients gave their consent to participate in a skin biopsy trial. Skin biopsies were performed before and after transplantation. The main objective was to assess whether biopsies of normal and affected skin from patients allografted with BSC showed a different histopathological and immunohistochemical pattern as compared to biopsies taken from patients allografted with BM. In addition, we wished to clarify whether sequential skin biopsies could be of prognostic value with regard to graft-versus-host disease (GVHD). Biopsies from normal or affected skin in BSC allografted did not disclose a different pattern as compared to BM transplants. Biopsies taken before the outbreak of acute and chronic GVHD showed no substantial differences between the groups. Irrespective of the type of allograft, the immunohistochemical picture of affected skin consistent with acute GVHD was dominated by a significantly higher number of T-lymphocytes (CD8+). Biopsies from normal skin before the outbreak of GVHD had no predictive value with regard to the development of acute or chronic GVHD. Immunohistochemistry is of supplementary help in distinguishing changes caused by cytotoxic agents from those caused by acute GVHD.

We compared the donation of bone marrow (BM) versus recombinant human granulocyte colony-stimulating factor-mobilized peripheral blood progenitor cells (PBPC) in HLA-matched sibling donors. Donors randomized to donate BM or PBPC completed questionnaires (Profile of Mood States [POMS] and Short-Form 36 Health Survey) assessing peridonation health-related quality of life (QoL), donation experience, and acceptability of donation before and 1 week and 4 weeks after donation. Between January 1996 and March 1999, 184 patients and their donors were randomized. Predonation and postdonation data were available on 52 (56%) and 35 (38%) of the BM and PBPC donors, respectively. The median donor age was 45 years, and 44% were female. The median time (range) to return to full activity for the BM and PBPC donors was 4 days (1-21 days) and 2 days (0-21 days), respectively (P = .01). One week after donation, BM donors reported more fatigue and less energy than the PBPC donors. BM donors' POMS total mood disturbance scores were worse 1 week after versus before donation, whereas the PBPC donors' scores did not change. POMS subscores indicated more fatigue and less energy in the BM versus PBPC donors. Anxiety improved in both groups, but more in PBPC donors. Four weeks after donation, the Short-Form 36 Health Survey indicated persistent moderate negative effects on QoL with BM donation versus small effects with PBPC donation. BM donation was associated with more physical morbidity and negative effects on QoL up to 1 month after donation than was PBPC donation. Despite this, most donors would donate again. Further work is needed to decrease donor anxiety and symptoms. If both BM and PBPC donation are feasible, then the graft source should be dictated by the predicted patient outcome as determined from the results of randomized trials.

Autologous peripheral blood stem cell transplantation for multiple myeloma offers higher response rates and improved survival compared with conventional chemotherapy. However, successful autografting requires effective cytoreduction and rapid hematologic reconstitution. We conducted a prospective randomized clinical trial to assess the efficacy of 2 cycles of priming chemotherapy with either granulocyte colony-stimulating factor (G-CSF) or granulocyte-macrophage colony-stimulating factor (GM-CSF) for peripheral blood stem cell mobilization followed by autologous transplantation. The major study end points were the comparative utility of G-CSF versus GM-CSF, the percentage of patients achieving complete response after transplantation, and overall and progression-free survival. Priming chemotherapy included cyclophosphamide (4 g/m2), mitoxantrone (8 g/m2 every day for 2 days), and dexamethasone (20 mg/m2 every 12 hours for 2 days) followed by randomization to either G-CSF or GM-CSF daily until completion of leukapheresis. Conditioning for transplantation included cyclophosphamide (75 mg/kg every day for 2 days) plus total body irradiation (165 cGy twice daily for 3 days), and patients received maintenance immunotherapy with interferon alpha. Seventy-two patients were randomized, and 64 underwent autologous transplantation. The median age at transplantation was 52 years, and the median time from diagnosis to transplantation was 10 months; 58% of the patients had received >4 cycles of pretransplantation chemotherapy. The median number of CD34+ cells obtained after mobilization was 16.4 x 10(6)/kg in the G-CSF arm versus 12.8 x 10(6)/kg in the GM-CSF arm (P = .8). Neutrophil recovery was faster in the G-CSF group after both cycle 1 (median, 13 days with G-CSF and 16 days with GM-CSF; P < .01) and cycle 2 (median, 13 days versus 17 days in the 2 groups, respectively; P = .03). Although platelet recovery was similar after cycle 1, platelet recovery to >100000/microL was notably faster in the G-CSF group both after cycle 2 and after transplantation (P = .03). Response and overall and disease-free survival were similar in both cohorts. Overall, 23% of the patients achieved a complete response after priming chemotherapy, which improved to 33% after transplantation. An additional 47% attained a partial response after transplantation, for a total response rate of 80%. With a median follow-up of 2 years (range, 0.7-8 years), the overall survival was 88% (95% confidence interval [CI], 80%-96%) at 1 year and 65% (95% CI, 51%-79%) at 3 years. Progression-free survival was 73% (95% CI, 62%-84%) at 1 year and 40% (95% CI, 26%-54%) at 3 years. Relapse or progressive disease was the most common cause of death (25 [83%] of 30 deaths). We conclude that mobilization with chemotherapy plus G-CSF versus GM-CSF results in similar CD34+ progenitor collections, even in patients exposed to multiple cycles of alkylator-based chemotherapy. Earlier neutrophil and platelet recovery was seen with G-CSF priming. Two cycles of priming chemotherapy plus autologous transplantation yields survival rates similar to those in published reports, including those using tandem transplantation.

The purpose of this study was to investigate the prognostic effects of four biological markers, BCL2, TP53, Ki-67, and P-glycoprotein, and their possible clinical relevance in addition to the international prognostic index (IPI) in diffuse large B-cell lymphoma (DLBCL). A total of 405 patients with aggressive lymphoma, stage II-IV, between 18 and 67 years, were randomized in a trial comparing CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisone) with MACOP-B (methotrexate, doxorubicin, cyclophosphamide, vincristine, prednisone, and bleomycin). Of these, 267 cases were classified as DLBCL, with adequate paraffin blocks available in 207 cases, enabling immunohistochemical assessment of the expression of BCL2, TP53, P-glycoprotein, and Ki-67. In a multivariate analysis, stratified for IPI, high BCL2 expression (>10%) low (<60%) expression of Ki-67, and high TP53 protein expression (>75%) were shown to provide additional prognostic information with regard to overall or failure-free survival. We found no association between expression of P-glycoprotein and outcome. Assessment of BCL2 positivity might be introduced as part of the routine investigation in patients with DLBCL, but further studies are necessary to confirm the clinical relevance of Ki-67 and TP53 expression.

G-CSF is used to enhance hematopoietic recovery after autologous stem cell transplantation (ASCT), but the optimal dose of G-CSF during engraftment has not been established. The medical cost of ASCT is a serious financial burden in developing countries, and G-CSF is the most costly drug used in this procedure. We evaluated whether a lower, vial-size fitted dose of lenograstim is clinically equivalent to a higher fixed dose.

We investigated the mechanisms by which leukotriene receptor antagonists decrease airway eosinophil number. In a randomized, double-blind crossover study, we examined the effects of 2 weeks of treatment with pranlukast 300 mg twice a day or placebo on allergen-induced changes in airway eosinophil number and bone marrow eosinophil progenitors in 15 subjects with mild asthma. Pranlukast treatment for 2 weeks decreased mean sputum eosinophil count from 0.15 x 10(6)/g (5.3% of cells) before treatment to 0.02 x 10(6)/g (0.7% of cells) after treatment (p < 0.05), whereas placebo did not. Pranlukast also decreased the eosinophil count (5.6% at 7 hours and 7.5% at 24 hours) (p < 0.05) after allergen inhalation compared with placebo (13.8% at 7 hours and 15.3% at 24 hours). There was a similar trend for sputum cells immunostaining for EG2, eotaxin, interleukin-5, and regulated upon activation, normal T cell expressed and secreted. Pranlukast also significantly attenuated the allergen-induced increase in the number of bone marrow eosinophil/basophil cfu (mean 0.3) at 24 hours compared with placebo (mean 6.2). The proportion of CD34(+) cells expressing the eotaxin receptor CC chemokine receptor 3, 24 hours after allergen inhalation, was also reduced by pranlukast. We conclude that, the cysteinyl leukotriene receptor antagonist, pranlukast, attenuates allergen-induced increase in airway eosinophils by decreasing bone marrow eosinophilopoiesis and airway chemotactic and eosinophilopoietic cytokines.

It is important to get high quality autologous peripheral blood stem cell (APBSC) for successful peripheral blood stem cell transplantation. Cyclophosphamide (CTX) plus recombined human granulocyte colony-stimulating factor (rhG-CSF) is standard regimen for APBSC mobilization. Etoposide plus rhG-CSF is another regimen for mobilization in recent years. The purpose of this study was to observe and compare the effects of these two regimens in APBSC mobilization for the patients with malignant lymphoma and germ cell tumors.

A total of 31 adult patients with AML entered in the EORTC/GIMEMA AML-10 trial, who received autologous stem cell transplantation (ASCT) after induction and consolidation chemotherapy, were prospectively evaluated for minimal residual disease (MRD) by multidimensional flow cytometry (MFC). Using a cutoff level of 3.5 x 10(-4) leukemic cells pre-ASCT, 12 patients (39%) were stratified to MRD high-risk group and 19 (61%) into MRD low-risk group. During follow-up, all patients who were in the high-risk group relapsed at a median time of 7 months; in the low-risk group, five patients relapsed at a median time of 11 months and 14 remained in remission for 56 (range 7-80) months (P=0.00004). Longitudinal MFC determinations post-ASCT showed increased MRD levels in three of the five patients who underwent subsequent relapse, while disease recurrence was unpredicted in the remaining two cases. The pre-ASCT MRD status was the factor most strongly associated with relapse risk in the multivariate analysis (P=0.0014). We conclude that: (1) pre-ASCT MRD status predicts successful outcome in patients receiving ASCT; (2) high-dose chemotherapy conditioning regimen followed by ASCT has no impact on the unfavorable prognostic value of high pre-ASCT MRD level; and (3) sequential MRD monitoring post-ASCT may allow the prediction of impending relapse.
