The prognostic impact of functional imaging with (123)I-mIBG in patients with stage 4 neuroblastoma >1 year of age on a high-risk treatment protocol: results of the German Neuroblastoma Trial NB97. Eur J Cancer 2008; 44:1552-8.

Abstract
AIM/PURPOSE (123)I-meta-iodobenzylguanidine ((123)I-mIBG) scintigraphy is well established for staging and evaluation of response in children with high-risk neuroblastoma but its prognostic value in highly intensive first-line treatment protocols is uncertain. The presence of any (123)I-mIBG positive tumour tissue was correlated with event-free survival (EFS) and overall survival (OS). PATIENTS AND METHODS The prognostic impact of residual (123)I-mIBG uptake into the primary tumour and metastases for predicting outcome in 113 stage 4 neuroblastoma patients >1 year of the German Neuroblastoma Trial NB97 was assessed using a univariate log-rank test and multivariate Cox regression analysis. RESULTS All patients had (123)I-mIBG positive disease at initial staging. After four courses of induction chemotherapy, 71% of patients were still (123)I-mIBG positive for the primary tumour and 61% for metastases. After six courses, 39% of patients had (123)I-mIBG uptake by the primary tumour and 45% residual (123)I-mIBG positive metastatic disease. The (123)I-mIBG status of the primary tumour site had no bearing on outcome. Residual (123)I-mIBG positive metastatic disease after four (3-y-EFS 25.7+/-5.3% versus 55.9+/-7.6%, p=0.009; 3-y-OS 49.8+/-6.1% versus 65.0+/-7.3%; p=0.021) and after six chemotherapy cycles (3-y-EFS 27.5+/-6.2% versus 47.4+/-6.4%, p=0.011; 3-y-OS 50.5+/-7.1% vs 60.0+/-6.4%, p=0.031) was associated with poor outcome. CONCLUSION Functional imaging with (123)I-mIBG scintigraphy can identify poor responders with any persistent metastatic (123)I-mIBG uptake who are at a high risk of disease relapse. (123)I-mIBG response of the primary tumour site had no bearing on outcome.

Abstract
PURPOSE We prospectively studied the efficacy of high dose therapy (HDT) versus an oral maintenance treatment (OMT) in patients with stage IV soft tissue sarcoma (STS). PATIENTS AND METHODS Both groups were pretreated with the CEVAIE combination consisting of carboplatin, etoposide, vincristine, actinomycin D, ifosfamide, and epirubicin. HDT consisted of a tandem cycle of thiotepa (600 mg/m(2)) plus cyclophosphamide (4,500 mg/m(2)) and melphalan (120 mg/m(2)) plus etoposide (1,800 mg/m(2)). This treatment was compared with OMT, consisting of four cycles trofosfamide (10 days 2 x 75 mg/m(2)/day) plus etoposide (10 days 2 x 25 mg/m(2)/day), and 4 cycles trofosfamide (10 days 2 x 75 mg/m(2)/day) plus idarubicin (10 days 4 x 5 mg/m(2)). Eligibility criteria were: diagnosis confirmed by reference pathology, primary stage IV, below 22 years of age, and having completed the study therapy. RESULTS From 96 patients 45 were treated with HDT and 51 with OMT. The main risk parameters were equally distributed in both arms. After a median follow-up of 57.4 months, 11/45 (24.4%) patients in the HDT-arm and 26/51 (57.8%) patients in OMT-arm were alive. Kaplan-Meier analysis demonstrated an overall survival for the whole group of 0.27 (OMT group: 0.52, HDT group 0.27, log rank P = 0.03). The proportional hazard analysis for patients with rhabdomyosarcoma (RMS) or "RMS-like" tumors (77.1% of all patients) demonstrated an independent benefit of OMT on outcome. CONCLUSION Oral maintenance therapy seems to be a promising option for patients with RMS-like stage IV tumors.

Abstract
BACKGROUND The current standard treatment for patients with high-risk neuroblastoma includes initial induction chemotherapy with a 21-day interval between induction treatments. We aimed to assess whether an intensive chemotherapy protocol that had a 10-day interval between treatments would improve event-free survival (EFS) in patients aged 1 year or over with high-risk neuroblastoma. METHODS Between Oct 30, 1990, and March 18, 1999, patients with stage 4 neuroblastoma who had not received previous chemotherapy were enrolled from 29 centres in Europe. Patients were randomly assigned to rapid treatment (cisplatin [C], vincristine [O], carboplatin [J], etoposide [E], and cyclophosphamide [C], known as COJEC) or standard treatment (vincristine [O], cisplatin [P], etoposide [E], and cyclophosphamide [C], ie, OPEC, alternated with vincristine [O], carboplatin [J], etoposide [E], and cyclophosphamide [C], ie, OJEC). Both regimens used the same total cumulative doses of each drug (except vincristine), but the dose intensity of the rapid regimen was 1.8-times higher than that of the standard regimen. The standard regimen was given every 21 days if patients showed haematological recovery, whereas the rapid regimen was given every 10 days irrespective of haematological recovery. Response to chemotherapy was assessed according to the conventional International Neuroblastoma Response Criteria (INRC). In responders, surgical excision of the primary tumour was attempted, followed by myeloablation (with 200 mg/m2 of melphalan) and haemopoietic stem-cell rescue. Primary endpoints were 3-year, 5-year, and 10-year EFS. Data were analysed by intention to treat. This trial is registered on the clinical trials site of the US National Cancer Institute website, number NCT00365755, and also as EU-20592 and CCLG-NB-1990-11. FINDINGS 262 patients, of median age 2.95 years (range 1.03-20.97), were randomly assigned-132 patients to standard and 130 patients to rapid treatment. 111 patients in the standard group and 109 patients in the rapid group completed chemotherapy. Chemotherapy doses were recorded for 123 patients in the standard group and 126 patients in the rapid group. 97 of 123 (79%) patients in the standard group and 84 of 126 (67%) patients in the rapid group received at least 90% of the scheduled chemotherapy, and the relative dose intensity was 1.94 compared with the standard regimen. 3-year EFS was 24.2% for patients in the standard group and 31.0% for those in the rapid group (hazard ratio [HR] 0.86 [95% CI 0.66-1.14], p=0.30. 5-year EFS was 18.2% in the standard group and 30.2% in the rapid group, representing a difference of 12.0% (1.8 to 22.3), p=0.022. 10-year EFS was 18.2% in the standard group and 27.1% in the rapid group, representing a difference of 8.9% (-1.2 to 19.0), p=0.085. Myeloablation was given a median of 55 days earlier in patients assigned rapid treatment than those assigned standard treatment. Infective complications (numbers of patients with febrile neutropenia and septicaemia, and if given, time on antibiotic and antifungal treatment) and time in hospital were greater with rapid treatment. Occurrence of fungal infection was the same in both regimens. INTERPRETATION Dose intensity can be increased with a rapid induction regimen in patients with high-risk neuroblastoma. There was no significant difference in OS between the rapid and standard regimens at 5 years and 10 years. However, an increasing difference in EFS after 3 years suggests that the efficacy of the rapid regimen is better than the standard regimen. A rapid induction regimen enables myeloablation to be given much earlier, which might contribute to a better outcome.

Abstract
Chest wall tumors in childhood are major challenges with respect to diagnostic workup and treatment. Incidence rate is less than 1 per 1,000,000 and various benign and malignant diseases are noted. From the malignant diseases, Ewing tumors and rhabdomyosarcoma tumors are most often seen. Depending on diagnosis, staging, and age, therapy has to be tailored for each patient, which should be discussed in a multidisciplinary team setting. Radical resection is in most cases the major component of treatment. Use of chemotherapy depends on the diagnosis. In soft-tissue tumors, previously considered to be chemotherapy insensitive, favorable results are currently reported. The role of radiotherapy is debated owing to its pronounced late sequelae in children, but should be added when adequate margins cannot be achieved by surgery.

Abstract
PURPOSE To determine the response to radionuclide targeted therapy with I-131-metaiodobenzylguanidine ((131)I-MIBG) as induction therapy in high-risk neuroblastoma patients. PATIENTS AND METHODS The protocol dictated at least two cycles of (131)I-MIBG with a fixed dose of 7.4 and 3.7 GBq, respectively, followed by surgery, if feasible, or followed by neoadjuvant chemotherapy and surgery. This was followed by consolidation with four courses of chemotherapy myeloablative chemotherapy and autologous stem-cell transplantation (ASCT). Consolidation therapy with 13-cis-retinoic acid was given for 6 months. RESULTS Of 44 consecutive patients, 41 were evaluable after two courses of (131)I-MIBG. The objective response rate at this point was 66%. In 24 patients, (131)I-MIBG was continued as pre-operative induction treatment. Seventeen patients required additional chemotherapy before surgery. After pre-operative therapy and surgery, the overall response rate was 73%. CONCLUSION First line (131)I-MIBG-targeted therapy is a valuable tool in the treatment of MIBG-positive high-risk neuroblastoma patients.

Abstract
Neuroblastoma, a neoplasm of the sympathetic nervous system, is the second most common extracranial malignant tumor of childhood and the most common solid tumor of infancy. Neuroblastoma is a heterogeneous malignancy with prognosis ranging from near uniform survival to high risk for fatal demise. Neuroblastoma serves as a paradigm for the prognostic utility of biologic and clinical data and the potential to tailor therapy for patient cohorts at low, intermediate, and high risk for recurrence. This article summarizes our understanding of neuroblastoma biology and prognostic features and discusses their impact on current and proposed risk stratification schemas, risk-based therapeutic approaches, and the development of novel therapies for patients at high risk for failure.

Abstract
Although great advances have been made in the treatment of low- and intermediate-risk neuroblastoma in recent years, the prognosis for advanced disease remains poor. Therapies based on monoclonal antibodies that specifically target tumour cells have shown promise for treatment of high-risk neuroblastoma. This article reviews the use of monoclonal antibodies either as monotherapy or as part of a multifaceted treatment approach for advanced neuroblastoma, and explains how toxins, cytokines, radioactive isotopes or chemotherapeutic drugs can be conjugated to antibodies to enhance their effects. Tumour resistance, the development of blocking antibodies, and other problems hindering the effectiveness of monoclonal antibodies are also discussed. Future therapies under investigation in the area of immunotherapy for neuroblastoma are considered.

Abstract
OBJECTIVE To determine whether neuroblastoma (NB) minimal residual disease (MRD) in bone marrow (BM) detected by flow cytometry could predict prognosis and whether tumor cell purging by CD34(+) cell selection prior to transplantation will impact on disease-free survival. METHODS NB MRD in BM was evaluated by flow cytometry with CD45-FITC-/CD81-PE+/CD56-PECy5+ monoclonal antibodies cocktail. Peripheral blood stem cell (PBSC) was enriched via positive CD34(+) cell selection by magnetic-activated cell separation system (MACS). RESULTS Eleven of 31 patients with CD45(-)/CD81+/CD56+ cells by flow cytometry at diagnosis became negative after an average of four courses of chemotherapy. All 11 patients remained alive without evidence of disease. Thirteen of the 20 patients with positive MRD relapsed and 1 patient died from disease (mean 25.8 months). There was a significant difference between these two groups. MRD in BM was tested before PBSC transplantation (PBSCT) for 19 NB patients. Fourteen was negative, 4 of them relapsed and 10 patients remained alive without evidence of disease. Another 5 patients with positive MRD, all of them relapsed (mean 17 months after PBSCT) with a significant difference between these two groups. Fourteen of 19 PBSC were purged with CD34(+) selection procedure. Six of 14 relapsed (mean 18.43 months after PBSCT). Five patients did not purge for CD34(+) selection, and 3 of them relapsed with no significant difference between these two groups. CONCLUSIONS Positive MRD in BM after an average of four courses of chemotherapy and before PBSCT is an unfavorable factor for stage IV NB. CD34(+) selection purging for PBSCT may not improve the prognosis for children with neuroblastoma in advanced stage.

Abstract
High-risk neuroblastoma is a childhood malignancy with a poor prognosis. Gradual improvements in survival have correlated with therapeutic intensity, and the ability to harvest, process and store autologous hematopoietic stem cells has allowed for dose intensification beyond marrow tolerance. The use of high-dose chemotherapy with autologous hematopoietic stem cell rescue in consolidation has resulted in improvements in survival, although further advances are still needed. Newer approaches to SCT and supportive care, most notably the transition to PBSC, have resulted in further improvement in survival and decreases in treatment-related mortality. Research into experimental approaches to hematopoietic SCT is ongoing.

Abstract
BACKGROUND Information on the incidence of infectious complications during for treatment for high risk neuroblastoma (HR-NB) is limited. Bacteremias and invasive mycoses may be considered surrogate markers of the infection burden. PATIENTS AND METHODS Data on bacteremias and invasive mycoses occurring during 3 consecutive protocols for front line (NB-89; NB-92; NB-97) or salvage therapy (TVD) for HR-NB were reviewed. The cumulative risk of developing a first episode and the rate of infections during the entire length of each protocol were evaluated. RESULTS Front line protocols were given to 80 patients for a total of 22,070 days at risk; salvage treatment was given to 24 children for 2,909 days at risk. During front line therapy 41 infectious episodes were diagnosed in 29 (36%) patients, for a 45% cumulative risk and an infection rate (IR) of 0.19/100 patient-days-at risk. Salvage therapy determined five infectious episodes in four (17%) patients, with a 39% cumulative risk, and an IR of 0.17. The IR during the phase of high dose chemotherapy with hematopoietic stem cell rescue (megatherapy) included in the three front line protocols decreased over time (1.54 in NB-89; 0.52 in NB-92 and 0.0 in NB 97; P = 0.001), possibly because of the use of less aggressive conditioning regimens, without radiotherapy. CONCLUSIONS The IRs of protocols for HR-NB did not change over time. The megatherapy-related phases are those at highest risk.

Abstract
The aim of the present study was to identify trends in numbers of European patients treated with autologous and allogeneic haematopoietic stem cell transplantation (HSCT) as well as to provide anticipated transplant rates for the upcoming years. The following indications were considered: haematological malignancies (acute leukaemias, myeloproliferative disorders, lymphoproliferative disorders and multiple myeloma), solid tumours and non-malignant diseases. Numbers of patients treated from 1990 to 2004 were extracted from the European Group for Blood and Marrow Transplantation database, extrapolated to 2012 using mathematic models and adjusted to the literature study and expert opinion. In Europe, a 13% raise in HSCT utilisation is to be expected from 2005 to 2010, mostly due to the growing application of reduced-intensity conditioning regimens followed by allogeneic HSCT. Growing transplant rates are likely to exert health expenditure budgets and put pressure on health care providers and health insurers in Europe. Therefore, the rapid expansion would ideally imply a simultaneous increase in HSCT budgets.

Abstract
We retrospectively analysed the outcomes of children transplanted for high-risk neuroblastoma (NB) at a single institution predominantly transplanted with total body irradiation and chemotherapy. The aims of this study were to determine the prognostic impact of clinical and biological features and to document long-term health outcomes. Forty patients were transplanted with a single unpurged autograft. Fourteen patients died from disease progression and two from late complications of treatment. Twenty-three patients are alive at a median of 4.6 years from diagnosis. Kaplan-Meier estimates of overall survival at 2, 5 and 10 years are 76+/-7.0, 60.2+/-8.4 and 54.7+/-9.3% following transplant. Response to induction therapy was significantly associated with survival (P<0.01). Long-term complications included growth (100%) and pubertal failure (83%), hearing impairment (73%), orthopaedic complications (63%), renal impairment (47%) and thyroid abnormalities (36%). Intrinsic and acquired resistance to chemotherapy remains the major obstacle to improving outcomes in high-risk NB. Although patients with chemo-sensitive disease are less likely to experience a relapse, substantial therapy-related toxicities result in poor long-term health outcomes for survivors.

Abstract
The clinical hallmark of neuroblastoma is heterogeneity, with the likelihood of cure varying widely according to age at diagnosis, extent of disease, and tumour biology. A subset of tumours will undergo spontaneous regression while others show relentless progression. Around half of all cases are currently classified as high-risk for disease relapse, with overall survival rates less than 40% despite intensive multimodal therapy. This Seminar focuses on recent advances in our understanding of the biology of this complex paediatric solid tumour. We outline plans for the development of a uniform International Neuroblastoma Risk Group (INRG) classification system, and summarise strategies for risk-based therapies. We also update readers on new discoveries related to the underlying molecular pathogenesis of this tumour, with special emphasis on advances that are translatable to the clinic. Finally, we discuss new approaches to treatment, including recently discovered molecular targets that might provide more effective treatment strategies with the potential for less toxicity.

Abstract
For over 30 years, stem cells have been used in the replenishment of blood and immune systems damaged by the cancer cells or during treatment of cancer by chemotherapy or radiotherapy. Apart from their use in the immuno-reconstitution, the stem cells have been reported to contribute in the tissue regeneration and as delivery vehicles in the cancer treatments. The recent concept of 'cancer stem cells' has directed scientific communities towards a different wide new area of research field and possible potential future treatment modalities for the cancer. Aim of this review is primarily focus on the recent developments in the use of the stem cells in the cancer treatments, then to discuss the cancer stem cells, now considered as backbone in the development of the cancer; and their role in carcinogenesis and their implications in the development of possible new cancer treatment options in future.

PURPOSE Relapsed high-risk neuroblastoma patients still have a poor prognosis. This phase-II trial assessed a new topotecan containing chemotherapy approach in patients with active disease. METHODS Chemotherapy consisted of topotecan (1.0 mg/m(2)/day 168-h continuous infusion), cyclophosphamide (100 mg/m(2)/day 1-h-infusion days 1-7 starting 6 h prior to topotecan), and etoposide (100 mg/m(2)/day 1-h-infusion days 8-10). Patients with relapsed neuroblastoma were scheduled for six cycles, untreated patients for two cycles followed by standard high-risk treatment. RESULTS Main toxicity observed during 153 cycles were grade 3-4 leukopenia (97% of cycles), thrombocytopenia (92%), neutropenic fever (52%), and mucositis (10%). No treatment related fatal toxicity occurred. Complete or partial response was achieved in 19 of 31 (61%) evaluable relapsed patients and 8 of 11 (72%) untreated patients. CONCLUSIONS The combination of topotecan, cyclophosphamide, and etoposide is tolerable and effective in relapsed and untreated neuroblastoma. Myelotoxicity is the main side effect but seems justified in view of the encouraging response rates. A randomized phase-III trial in primary disease has been commenced.

Abstract
From June 1997 to August 2005, 52 consecutive newly diagnosed stage 4 neuroblastoma patients over 1 year of age were assigned to receive tandem high-dose chemotherapy and autologous stem cell rescue (HDCT/ASCR) as consolidation therapy. Fifty of the 52 patients underwent a first HDCT/ASCR and 44 patients underwent a second HDCT/ASCR. Eight patients (15.4%) died from treatment-related toxicity (seven during the second HDCT/ASCR). Total body irradiation (TBI) in the first HDCT/ASCR and a shorter interval (< 12 weeks) between the first and second HDCT/ASCR were associated with a higher rate of treatment-related death in the second HDCT/ASCR (P = 0.032 and 0.095, respectively). The tumor relapsed or progressed in 11 patients, and 33 patients remained event free with a median follow-up of 53 months (range 19-117) from diagnosis. The 5-year event-free survival (EFS) (+/- 95% confidence interval) for all 52 patients was 62.1+/-13.7%. The application of TBI and local radiotherapy, and a longer interval between the first and second HDCT/ASCR were independently associated with a better EFS (P = 0.026, 0.007 and 0.020, respectively). However, further studies will be needed to decrease the toxic death rate in the second HDCT/ASCR while reducing the relapse rate.

Abstract
BACKGROUND/PURPOSE This study aims to clarify the implications of MYCN amplification in patients with high-risk neuroblastomas treated with 2 different regimens of induction chemotherapy established by the Japan Study Group for Advanced Neuroblastoma. METHODS Between 1985 and 2003 in Japan, 392 patients with stage 4 neuroblastomas who were older than 12 months were treated with 2 regimens of induction chemotherapy (the combination of cyclophosphamide [CTX], cisplatin [CDDP], pirarubicin, and vincristine or etoposide). Regimen 91A3 or 98A3 (A3) (CTX 2400 mg/m2, CDDP 125 mg/m2) was a higher dose combination of CTX and CDDP than regimen 85A1 or 91A1 (A1) (CTX 1200 mg/m2, CDDP 90 mg/m2). The 392 cases were classified into 3 groups (A, 1 copy; B, 2-9 copies; C, more than 10 copies) based on the MYCN amplification status by a Southern blot analysis. RESULTS The 5-year overall survival rate (5-YS) was 41.1% for all 392 cases. Regarding the MYCN amplification status, the 5-YS was 46.6% for A group (n = 227), 22.7% for B group (n = 26), and 36.0% for C group (n = 139). A fluorescence in situ hybridization analysis showed the presence of the cells with more than 10 copies in cases with 2 to 9 copies based on the Southern blot findings. Of the 227 patients in a group, the 5-YS was 46.7% for the 70 cases treated by A3 and 47.0% for 154 cases treated by A1 (nonsignificant). The 5-YS of the 210 patients with stem cell transplantation (SCT) (51.%) was significantly better than that of the 127 patients without SCT (41.1%) (P < .05). CONCLUSIONS Regarding the MYCN amplification status, the tumor aggressiveness might thus be different between 2 and 9 copies and a single copy of MYCN. In neuroblastomas with 2 and 9 copies of MYCN based on a Southern blot analysis, the MYCN amplification status should be analyzed using the fluorescence in situ hybridization method. Induction chemotherapy followed by SCT according to the Japan Study Group for Advanced Neuroblastoma protocol improved the outcome of neuroblastomas with MYCN amplification; however, obtaining a further improvement in the long-term survival of stage 4 neuroblastomas may therefore require the development of an even more effective treatment modality.

Abstract
Novel therapeutic approaches are urgently needed for high-stage neuroblastoma, a major therapeutic challenge in pediatric oncology. The majority of neuroblastoma tumors are p53 wild type with intact downstream p53 signaling pathways. We hypothesize that stabilization of p53 would sensitize this aggressive tumor to genotoxic chemotherapy via inhibition of MDM2, the primary negative upstream regulator of p53. We used pharmacologic inhibition of the MDM2-p53 interaction with the small-molecule inhibitor Nutlin and studied the subsequent response to chemotherapy in neuroblastoma cell lines. We did 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide and terminal deoxynucleotidyl transferase assays to measure proliferation and apoptosis in several cell lines (IMR32, MYCN3, and JF) treated with combinations of cisplatin, etoposide, and Nutlin. We found consistent and robust decreases in proliferation and increases in apoptosis with the addition of Nutlin 3a to etoposide or cisplatin in all cell lines tested and no response to the inactive Nutlin 3b enantiomer. We also show a rapid and robust accumulation of p53 protein by Western blot in these cells within 1 to 2 hours of treatment. We conclude that MDM2 inhibition dramatically enhances the activity of genotoxic drugs in neuroblastoma and should be considered as an adjuvant to chemotherapy for this aggressive pediatric cancer and for possibly other p53 wild-type solid tumors.

Abstract
Currently, Pubmed lists 385 marker genes for neuroblastoma outcome. Using a customized neuroblastoma-microarray, we evaluated the prognostic impact of the gene-expression pattern of 349 of these candidates (90.6%) in 127 neuroblastoma patients with divergent outcome. By significance analysis of microarrays (SAM) and both uncorrected and Bonferroni-corrected ANOVA, 166/349 (47.5%), 218/349 (62.5%) and 128/349 (36.4%) candidates showed significant differential expression between patients with contrasting outcome. By Prediction Analysis for Microarrays (PAM), a 38-gene-classifier was derived from all markers, which classified patients outcome with an overall accuracy of 78.5%. However, patients with unfavorable outcome of MYCN non-amplified disease were largely misclassified (accuracy: 35%), suggesting that these courses are not identified by current marker genes.

Abstract
Purpose To report on an irinotecan and temozolomide regimen for neuroblastoma (NB). Quality of life and minimizing toxicity were major considerations. Patients and Methods The plan stipulated 5-day courses of irinotecan 50 mg/m2 (1-hour infusion) and temozolomide 150 mg/m2 (oral) every 3 to 4 weeks, with a pretreatment platelet count more than 30,000/μL. Granulocyte colony-stimulating factor was used when the absolute neutrophil count was less than 1,000/μL. Results Forty-nine NB patients received 1 to 15 courses (median, 5). Gastrointestinal and myelosuppressive toxicities were readily managed. Lymphocyte responses to phytohemagglutinin after 2 to 10 courses (median, 3.5) were normal in 10 of 10 patients treated after nonimmunosuppressive therapy, and normalized in five of seven patients first treated less than 2 months after high-dose alkylators. Of 19 patients treated for refractory NB and assessable for response, nine showed evidence of disease regression, including two complete responses and seven objective responses. Of 17 patients treated for progressive disease, three showed evidence of disease regression, including one partial response and two objective responses. Multiple courses entailed no cumulative toxicity and controlled disease for prolonged periods in many patients, including some who were unable to complete prior treatments because of hematologic, infectious, cardiac, or renal problems. Conclusion This regimen has anti-NB activity, spares vital organs, is feasible with poor bone marrow reserve, causes limited immunosuppression, and allows good quality of life.
