Autologous or allogeneic hematopoietic stem cells transplantation combined with high-dose chemotherapy for refractory neuroblastoma: A protocol for systematic review and meta-analysis. Medicine (Baltimore) 2021; 100:e28096. [PMID: 34889262 PMCID: PMC8663834 DOI: 10.1097/md.0000000000028096] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/12/2021] [Accepted: 11/15/2021] [Indexed: 01/05/2023] Open
Abstract
BACKGROUND Neuroblastoma is a common solid malignant tumor in children. Despite the development of new treatment options, the prognosis of high-risk neuroblastoma patients is still poor. High-dose chemotherapy and hematopoietic stem cell (HSC) transplantation might improve survival of patients with refractory neuroblastoma. In this study, we aimed to summarize the efficacy of autologous or allogeneic HSC transplantation combined with high-dose chemotherapy for patients with refractory neuroblastoma through the meta-analysis. METHODS AND ANALYSIS Relevant clinical trials of autologous or allogeneic HSC transplantation for the treatment refractory neuroblastoma patients will be searched in Web of Science, Cochrane Library, PubMed, Google Scholar, Embase, Medline, China National Knowledge Infrastructure, China Scientific Journal Database, Chinese Biomedical Literature Database and Wanfang Database from their inception to December 2020. Two researchers will perform data extraction and risk of bias assessment independently. The clinical outcomes including tumor response, overall survival, event-free survival (EFS), quality of life (QoL) and adverse events, were systematically evaluated by using Review Manager 5.3 and Stata 14.0 statistical software. RESULTS The results of this study will provide high-quality evidence for the effect of autologous or allogeneic HSC transplantation combined with high-dose chemotherapy on tumor response, survival, and QoL in patients with refractory neuroblastoma. CONCLUSIONS The conclusions of this meta-analysis will be published in a peer-reviewed journal, and provide more evidence-based guidance in clinical practice.

A multicentric randomized phase II clinical trial evaluating high-dose thiotepa as adjuvant treatment to standard chemotherapy in patients with resectable relapsed osteosarcoma. Eur J Cancer 2019; 125:58-68. [PMID: 31838406 DOI: 10.1016/j.ejca.2019.11.007] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2019] [Revised: 11/01/2019] [Accepted: 11/07/2019] [Indexed: 11/26/2022]
Abstract
BACKGROUND The role of high-dose chemotherapy in relapsing osteosarcomas has not been established. We evaluated the efficacy and tolerance of high-dose thiotepa (HDTp) after standard chemotherapy (SCT) in patients with relapsed osteosarcoma. PATIENTS AND METHODS This randomised open-label phase II study enrolled patients 1-50 years, with local or metastatic relapse of a high-grade osteosarcoma, not progressive after two cycles of SCT, for whom a complete surgery can be achievable following treatment. The trial assigned enrolled patients in a 1:1 ratio to receive two additional courses of SCT + HDTp and autologous transplantation (Arm A), or SCT alone (Arm B). Surgery for complete resection was scheduled as soon as feasible. Primary endpoint was overall survival (OS). Secondary objectives included progression-free survival (PFS) and safety. RESULTS From September 2009 to November 2016, 44 patients were randomised (A:22; B:22). In total, 54.5% were males, and the median age was 16 years (9-32years). The two-year OS rate was 66.7% (95% CI 42.5-82.5) (SCT + HDTp, Arm A) versus 50.0% (95% CI 28.2-68.4) for SCT alone (Arm B). Median OS was 27.4 and 24.8 months, respectively (hazard ratio [HR] 0.826, 95% CI 0.393-1.734; p = 0.6123). Median PFS was 15.6 (8.9-24.9) months in Arm A versus 7.2 (4.8-33.3) months in Arm B, p = 0.3845. Among the 22 patients treated with SCT + HDTp, 16 (72.7%) experienced at least one grade ≥3 adverse events versus 18/22 (81.8%) patients treated with SCT. No toxic death occurred. CONCLUSION Adjuvant HDTp failed to significantly improve OS and PFS in resectable relapsed osteosarcomas. Despite a trend of prolonged survival and an acceptable toxicity, thiotepa cannot be recommended. KEY MESSAGE HDTp and autologous transplantation added to SCT did not improve OS and PFS in patients with resectable relapsed osteosarcomas. Despite a trend of prolonged survival, thiotepa cannot be recommended.

Abstract
The prognosis of resistant or relapsing children with neuroblastoma remains very poor, and the search for new therapies is ongoing. In this analysis, we assessed the toxicity of a treosulfan, melphalan, and thiotepa (TMT) regimen in 17 children with recurrent or refractory neuroblastoma who underwent stem cell transplantation (SCT). For allogeneic SCT, fludarabine and antithymocyte globulin were added. The stem cell source was autologous in 8 patients, haploidentical in 8 patients, and a matched unrelated donor in 1 patient. The reported nonhematologic toxicities included grade 3 mucositis, grade 1 to 3 hypertransaminasemia, and in 3 patients, veno-occlusive disease. No neurologic, cardiac, or dermatologic toxicities were observed. The probability of overall survival (OS) in patients with primary resistance was superior to that in patients with relapsed disease (100% versus 22.6%; P = .046). Post-transplantation dinutuximab beta immunotherapy was associated with superior 5-year OS (66.7% versus 11.4%; P = .0007). The use of an allogeneic donor, previous autologous SCT with busulfan and melphalan, and pretreatment with high-dose metaiodobenzylguanidine therapy demonstrated no effect on outcomes. In 4 patients, TMT megatherapy alone was enough to achieve complete remission. The TMT conditioning regimen was well tolerated in heavily pretreated patients with neuroblastoma. The manageable toxicity and addition of new anticancer drugs with optional post-SCT immunotherapy or chemotherapy support further trials with the TMT regimen in patients with neuroblastoma.

Abstract
Background Serious neurological adverse events (NAE) have occurred during treatment with high-dose thiotepa regimens of children with high-risk solid tumours. The objective was to assess the incidence of NAE related to high-dose thiotepa and to identify potential contributing factors that could exacerbate the occurrence of this neurotoxicity. Methods From May 1987 to March 2011, children with solid tumours treated with high-dose thiotepa were retrospectively identified. Each NAE detected led to an independent case analysis. Potential contributing factors were pre-specified and univariate/multivariable analyses were performed. Results Three hundred seven courses of thiotepa (251 patients) were identified. The total dose per treatment ranged from 600 to 900 mg/m2. 81 NAE (26%) were identified. 46 NAE were related to high-dose thiotepa during the first course (18.3%) and 11 during the second course (19.6%). The symptoms appeared in a median time of 2 days after the introduction of thiotepa. Central and peripheral symptoms were headaches, tremors, confusion, seizures, cerebellar syndrome, and coma. High-dose thiotepa was reintroduced in 18 cases and symptoms reappeared in 5 children. For 3 patients who had seizures during the first course, premedication with clonazepam for the second course has prevented recurrence of NAE. As contributing factors, brain tumour and tramadol treatment increased the risk of thiotepa-related neurotoxicity by 2 to 6 times respectively. Conclusions The incidence of neurotoxicity was 18.3%. Brain tumours and tramadol treatment are risk factors to consider when using high-dose thiotepa. The outcome of patients was favourable without sequelae in all cases and rechallenge with thiotepa was possible.

Abstract
High-dose therapy (HDTx) with autologous stem cell rescue has been widely applied in very-poor-risk pediatric solid tumors. Promising data have become available with the use of high-dose busulfan, whereas high-dose (HD) thiotepa is less commonly used. We report retrospectively our single-institution experience from 1986 to 2012 of single and tandem HDTx with special emphasis on HD-thiotepa as the backbone of HD regimen in Ewing family tumors, including all 24 patients in the Helsinki University Hospital referral area in population-based fashion (Ewing sarcoma 9, Askin tumor 9, peripheral neuroectodermal tumor 6). The 10-year overall survival for the entire cohort was 0.73±0.01. Thirteen out of the 24 underwent HDTx (10 single, 3 tandem). The HDTx regimen consisted of HD-thiotepa (900 mg/m), VP16, and carboplatin. Additional HD-melphalan and total body irradiation were used in the tandem regimens. There was no toxic mortality. The 5-year event-free survival was 0.73±0.16 for high-risk cases transplanted in 1CR. In the relapse group, 1 out of the 3 survived. Radiotherapy to axial sites was given safely in combination with HD-thiotepa in all 3 patients. Thiotepa-based HDTx approach resulted in an encouraging outcome without toxic mortality for high-risk patients. HD-thiotepa merits further studies in larger controlled series.

Abstract
INTRODUCTION Osteosarcoma (OS), the most common primary malignant bone tumor, is currently treated with pre- and postoperative chemotherapy in association with the surgical removal of the tumor. Conventional treatments allow to cure about 60 - 65% of patients with primary tumors and only 20 - 25% of patients with recurrent disease. New treatment approaches and drugs are therefore highly warranted to improve prognosis. AREAS COVERED This review focuses on the therapeutic approaches that are under development or clinical evaluation in OS. Information was obtained from different and continuously updated data bases, as well as from literature searches, in which particular relevance was given to reports and reviews on new targeted therapies under clinical investigation in high-grade OS. EXPERT OPINION OS is a heterogeneous tumor, with a great variability in treatment response between patients. It is therefore unlikely that a single therapeutic tool will be uniformly successful for all OS patients. This claims for the validation of new treatment approaches together with biologic/(pharmaco)genetic markers, which may select the most appropriate subgroup of patients for each treatment approach. Since some promising novel agents and treatment strategies are currently tested in Phase I/II/III clinical trials, we may hope that new therapies with superior efficacy and safety profiles will be identified in the next few years.

Abstract
Introduction. Osteosarcoma relapse has a poor prognosis, with less than 25% survival at 5 years. We describe the experience of the French Society of Paediatric Oncology (SFCE) with high dose (HD) thiotepa and autologous stem cell transplantation (ASCT) in 45 children with relapsed osteosarcoma. Patients and Methods. Between 1992 and 2004, 53 patients received HD thiotepa (900 mg/m2) followed by ASCT in 6 centres. Eight patients were excluded from analysis, and we retrospectively reviewed the clinical radiological and anatomopathological patterns of the 45 remaining patients. Results. Sixteen girls and 29 boys (median age, 15.9 years) received HD thiotepa after initial progression of metastatic disease (2), first relapse (26), and second or third relapse (17). We report 12 radiological partial responses and 9 of 31 histological complete responses. Thirty-two patients experienced further relapses, and 13 continued in complete remission after surgical resection of the residual disease. Three-year overall survival was 40%, and 3-year progression-free survival was 24%. Delay of relapse (+/− 2 years from diagnosis) was a prognostic factor (P = 0.011). No acute toxic serious adverse event occurred. Conclusion. The use of HD thiotepa and ASCT is feasible in patients with relapsed osteosarcoma. A randomized study for recurrent osteosarcoma between standard salvage chemotherapy and high dose thiotepa with stem cell rescue is ongoing.

Abstract
While advances in the treatment of pediatric cancers have increased cure rates, children with metastatic or recurrent solid tumors have a dismal prognosis despite initial transient responses to therapy. Autologous hematopoietic stem cell transplantation takes advantage of the steep dose-response relationship observed with many chemotherapeutic agents. While clearly demonstrated to improve outcomes in patients with metastatic neuroblastoma, autologous hematopoietic stem cell transplantation is also frequently used to treat patients with other high-risk diseases such as Ewing sarcoma, osteosarcoma, rhabdomyosarcoma, Wilms' tumor, retinoblastoma, germ cell tumors, lymphomas and brain tumors. Most published experience consists of retrospective, single-arm studies; randomized clinical trials are lacking, due in part to the rarity of pediatric cancers treatable by autologous hematopoietic stem cell transplantation. These published literature demonstrate that autologous hematopoietic stem cell transplantation results in most cases in equivalent or superior outcomes when compared with conventional therapies. However, patient heterogeneity, patient selection, graft characteristics and processing and the varied conditioning regimens are additional factors to consider. Since the inception of autologous hematopoietic stem cell transplantation, regimen-related toxicity has markedly decreased and the vast majority of treatment failures are now due to disease recurrence. Prospective clinical trials are needed to identify specific high-risk patient populations, with randomization (when possible) to compare outcomes of patients undergoing autologous hematopoietic stem cell transplantation with those receiving standard therapy. In addition, investigators need to better define the role of autologous hematopoietic stem cell transplantation in these solid tumors, particularly in combination with other therapeutic modalities such as immunotherapy and novel cell processing methodologies.

Abstract
The prognosis for children with bone and soft tissue sarcomas has significantly improved since the advent of effective multiagent chemotherapy, aggressive surgery for local disease and more precise delivery of radiotherapy doses. However, in a small proportion of patients that present with high-risk disease, long-term outcome has not substantially increased, with disease-free survival rates still in the order of 20-30%. It is therefore clear that novel therapies are needed for children with these tumors. Based on the highly chemosensitive nature of the majority of pediatric sarcomas, several small studies have been conducted to investigate the potential role of high-dose chemotherapy followed by hematopoietic stem cell reconstitution. This review will provide an overview of the current literature concerning the use of high-dose therapy with stem cell transplantation for the three main pediatric sarcomas--Ewing sarcoma, rhabdomyosarcoma and osteosarcoma.

Abstract
Patients with advanced pediatric sarcomas have a poor prognosis and novel combination therapies are needed to improve the response rates. Hematological and organ related toxicities have been observed when administering topotecan in combination with, e.g., high dose thiotepa. This study evaluates the toxicity of escalating doses of topotecan alone or in combination with thiotepa or treosulfan. We compared the toxicity including death of complication (DOC) of topotecan alone or in combination with thiotepa or treosulfan in advanced pediatric sarcomas (n = 12). Ten of 12 patients (0.83) suffered from advanced tumors of the Ewing family (i.e., bone or marrow metastases or relapse <24 month after diagnosis, including one neuroepithelial tumor of the kidney) and two from alveolar rhabdomyosarcoma stage IV (0.17). Median age was 15 years (range 5-28). Ratio of female to male was 1:1. Two patients received topotecan alone (1.25 mg/m(2) q 5d and 1.5 mg/m(2) q 5d), three patients received four courses of topotecan (2 mg/m(2) q d 1-5) in combination with thiotepa (100 mg/m(2) q d 1-5), and seven patients received topotecan (2 mg/m(2) q d 1-5) in combination with treosulfan (10g/m(2) q d 3-5). Overall toxicity was not different between all three groups; mean scores were 1.6, 1.8, and 1.7 according to WHO grading (Scale 0-4). Organ related toxicity ranged between 0 and 4 and was not different as well. DOC was 0/2, 1/3, and 0/7 patients respectively. Escalating therapy with topotecan in combination with treosulfan has acceptable toxicity and warrants further investigation in advanced pediatric sarcomas.

Abstract
Background High grade primary bone sarcomas are rare cancers that affect mostly children and young adults. Osteosarcoma and Ewing sarcoma are the most common histological subtypes in this age group, with current multimodality treatment strategies achieving 55-70% overall survival. As there remains an urgent need to develop new therapeutic interventions, we have reviewed published phase I/II trials that have been reported for osteosarcoma and Ewing sarcoma in the last twenty years. Results We conducted a literature search for clinical trials between 1990 and 2010, either for trials enrolling bone sarcoma patients as part of a general sarcoma indication or trials specifically in osteosarcoma and Ewing sarcoma. We identified 42 clinical trials that fulfilled our search criteria for general sarcoma that enrolled these patient groups, and eight and twenty specific trials for Ewing and osteosarcoma patients, respectively. For the phase I trials which enrolled different tumour types our results were incomplete, because the sarcoma patients were not mentioned in the PubMed abstract. A total of 3,736 sarcoma patients were included in these trials over this period, 1,114 for osteosarcoma and 1,263 for Ewing sarcoma. As a proportion of the worldwide disease burden over this period, these numbers reflect a very small percentage of the potential patient recruitment, approximately 0.6% for Ewing sarcoma and 0.2% for osteosarcoma. However, these data show an increase in recent activity overall and suggest there is still much room for improvement in the current trial development structures. Conclusion Lack of resources and commercial investment will inevitably limit opportunity to develop sufficiently rapid improvements in clinical outcomes. International collaboration exists in many well founded co-operative groups for phase III trials, but progress may be more effective if there were also more investment of molecular and translational research into disease focused phase I/II clinical trials. Examples of new models for early translational and early phase trial collaboration include the European based EuroBoNeT network, the Sarcoma Alliance for Research through Collaboration network (SARC) and the new European collaborative translational trial network, EuroSarc.

Abstract
The prognosis for high-risk Ewing's tumors has been improved by multimodal radiation and chemotherapy. Ewing's family of tumors requires risk-adapted treatment. Risk stratification is dependent on stage, tumor localization and volume, and the pattern of disease spread at the time of diagnosis and the time of relapse. The concepts for high-dose therapy followed by hematopoietic cell transplantation in Ewing's family of tumors are based on dose-response and dose-intensity relationships. This article will discuss the use of high-dose therapy followed by hematopoietic cell transplantation, focusing on recent progress with respect to agent combinations, dose and outcomes of therapy.

Abstract
INTRODUCTION Patients with metastatic rhabdomyosarcoma (RMS) have a poor prognosis. The aim of this systematic review is to investigate whether high-dose chemotherapy (HDCT) followed by autologous hematopoietic stem cell transplantation (HSCT) in patients with metastatic RMS has additional benefit or harm compared to standard chemotherapy. METHODS Systematic literature searches were performed in MEDLINE, EMBASE, and The Cochrane Library. All databases were searched from inception to February 2010. PubMed was searched in June 2010 for a last update. In addition to randomized and non-randomized controlled trials, case series and case reports were included to complement results from scant data. The primary outcome was overall survival. A meta-analysis was performed using the hazard ratio as primary effect measure, which was estimated from Cox proportional hazard models or from summary statistics of Kaplan Meier product-limit estimations. RESULTS A total of 40 studies with 287 transplant patients with metastatic RMS (age range 0 to 32 years) were included in the assessment. We identified 3 non-randomized controlled trials. The 3-year overall survival ranged from 22% to 53% in the transplant groups vs. 18% to 55% in the control groups. Meta-analysis on overall survival in controlled trials showed no difference between treatments. Result of meta-analysis of pooled individual survival data of case series and case reports, and results from uncontrolled studies with aggregate data were in the range of those from controlled data. The risk of bias was high in all studies due to methodological flaws. CONCLUSIONS HDCT followed by autologous HSCT in patients with RMS remains an experimental treatment. At present, it does not appear justifiable to use this treatment except in appropriately designed controlled trials.

Abstract
BACKGROUND Soft tissue sarcomas (STS) are a highly heterogeneous group of rare malignant solid tumors. Non-rhabdomyosarcoma soft tissue sarcomas (NRSTS) comprise all STS except rhabdomyosarcoma. In patients with advanced local or metastatic disease, autologous hematopoietic stem cell transplantation (HSCT) applied after high-dose chemotherapy (HDCT) is a planned rescue therapy for HDCT-related severe hematologic toxicity. OBJECTIVES To assess the effectiveness and safety of HDCT followed by autologous HSCT for all stages of soft tissue sarcomas in children and adults. SEARCH STRATEGY We searched the electronic databases CENTRAL (The Cochrane Library 2010, Issue 2), MEDLINE and EMBASE (February 2010). Online trial registers, congress abstracts and reference lists of reviews were searched and expert panels and authors were contacted. SELECTION CRITERIA Terms representing STS and autologous HSCT were required in the title, abstract or keywords. In studies with aggregated data, participants with NRSTS and autologous HSCT had to constitute at least 80% of the data. Comparative non-randomized studies were included because randomized controlled trials (RCTs) were not expected. Case series and case reports were considered for an additional descriptive analysis. DATA COLLECTION AND ANALYSIS Study data were recorded by two review authors independently. For studies with no comparator group, we synthesised results for studies reporting aggregate data and conducted a pooled analysis of individual participant data using the Kaplan-Meyer method. The primary outcomes were overall survival (OS) and treatment-related mortality (TRM). MAIN RESULTS We included 54 studies, from 467 full texts articles screened (11.5%), reporting on 177 participants that received HSCT and 69 participants that received standard care. Only one study reported comparative data. In the one comparative study, OS at two years after HSCT was estimated as statistically significantly higher (62.3%) compared with participants that received standard care (23.2%). In a single-arm study, the OS two years after HSCT was reported as 20%. In a pooled analysis of the individual data of 54 participants, OS at two years was estimated as 49% (95% CI 34% to 64%). Data on TRM, secondary neoplasia and severe toxicity grade 3 to 4 after transplantation were sparse. All 54 studies had a high risk of bias. AUTHORS' CONCLUSIONS Due to a lack of comparative studies, it is unclear whether participants with NRSTS have improved survival from autologous HSCT following HDCT. Owing to this current gap in knowledge, at present HDCT and autologous HSCT for NRSTS should only be used within controlled trials.

Abstract
ThioTEPA is a chemotherapeutic agent used in the treatment of cancers, and more recently has been proposed as a component of high-dose therapy for young patients with recurrent malignant brain tumors. We previously demonstrated a significant dose-dependent reduction of cell proliferation in the dentate gyrus of the hippocampus in mice immediately following a 3-day regiment of thioTEPA. The aim of this study was to evaluate the long-term effects of thioTEPA treatment on hippocampal cell proliferation and potential effects on memory deficit or depression-related behavior in C57BL/6J mice. A 3-day regimen of thioTEPA (10mg/kg/d, i.p.) yielded a significant reduction in cell proliferation immediately after treatment as assessed by BrdU incorporation, and none of the labeled progeny that initially survived the treatment were detectable one week later. Following a 3-week rebound in proliferation following treatment, a significant deficit in proliferation reappeared and persisted for at least 21 weeks following treatment. ThioTEPA-treated mice subjected to an object recognition test 1, 2, 3, 4, 8, 12, 20 or 30 weeks following treatment demonstrated significant memory deficits at 12 and 20 weeks. Mice demonstrated a similar deficit in an object placement test when tested 20 weeks following thioTEPA treatment. However, no observable effects on performance in the Porsolt forced swim test or the tail suspension test were observed in thioTEPA-treated mice. Together, these studies suggest that cumulative long-term negative effects of thioTEPA treatment on proliferation of new cells in the dentate gyrus may contribute to cognitive impairments associated with its use in the treatment of cancer.

Abstract
AIM The RMS4.99 study was designed to explore the role of multiple sequential high-dose chemotherapy cycles administered early in the treatment of children with metastatic rhabdomyosarcoma. PATIENTS AND METHODS Seventy patients were enrolled and received three cycles of initial standard chemotherapy, followed by a course of cyclophosphamide and etoposide to obtain peripheral blood stem cells (PBSC), then three consecutive high-dose combinations followed by PBSC rescue. This was followed by surgery and/or radiotherapy, after which a final maintenance treatment with six courses of vincristine, actinomycin D and cyclophosphamide was administered. RESULTS Sixty-two patients underwent the high-dose chemotherapy phase. The 3-year overall survival (OS) and progression free survival (PFS) rates for the 70 patients were 42.3% (95% confidence interval [CI] 39.5-53.6) and 35.3% (95% CI, 24.3-46.5), respectively. By multivariate analysis survival correlated strongly with age > 10 years. In a subset of patients with only one or no unfavourable prognostic factors (age > 10 years, unfavourable site of primary tumour, bone or bone marrow involvement and number of metastatic sites >2) the PFS was significantly higher, i.e. 60.5% at 3 years. CONCLUSION Our study confirms that patients with favourable prognostic characteristics have a better survival. The use of sequential cycles of high-dose chemotherapy did not appear of benefit for patients with metastatic rhabdomyosarcoma.

Abstract
OBJECTIVE To evaluate the role of high-dose chemotherapy (HDC) and autologous stem cell transplantation (ASCT) as consolidation therapy for children with high-risk Ewing sarcoma (ES) treated at The Hospital for Sick Children (SickKids), Toronto. PATIENTS AND METHODS The charts of children treated for high-risk ES (defined as metastatic at diagnosis or relapsed) between 1990 and 2005 at SickKids were reviewed. Forty-five children were identified. Twenty patients received ASCT after induction with vincristine, doxorubicin, ifosfamide, cyclophosphamide, and etoposide. Patients with resectable tumor or lung metastases underwent surgery and those with non-resectable tumors were treated with irradiation. Twenty-five patients were treated with conventional chemotherapy (CC). Primary metastatic patients were treated with either a local protocol or as per POG 9354. At relapse, patients were treated with topotecan, cyclophosphamide, then ifosfamide, carboplatin, and etoposide (ICE). Local control was attained with surgery and/or irradiation. RESULTS Ten of the 20 patients treated with ASCT are alive (median follow-up 6 years), with 8/10 being in remission more than 5 years from diagnosis. The 3-year overall survival (OS) for ASCT was 59%, (95% CI: 36%, 81%) compared to 34% (14%, 53%) for patients treated with CC (P-value = 0.06). The 3-year event-free survival (EFS) for the ASCT was 39% (17%, 60%) compared to 32% (13%, 50%) in the CC group (P = 0.08). CONCLUSION ASCT appears to add some benefit to conventional multimodality therapy for children with high-risk ES. Randomized controlled trials are warranted.

Abstract
Ewing tumors remain of poor prognosis, with 5-year overall survival of 55% to 65% in localized patients and not exceeding 25% in primarily metastatic disease. Several reports, mainly in children, have reported that some patients with poor-risk Ewing tumors may benefit from high-dose chemotherapy (HDCT) with autologous stem cell rescue. This retrospective study analyzed 46 patients treated in our institution between 1987 and 2000 for localized or primary metastatic Ewing tumors by HDCT followed by stem cell rescue. Median follow up was 7.1 years. Median age was 21 years (range, 15-46 years). Twenty-two percent of patients had metastases at diagnosis. The tumor site was axial in 56% of patients. Median tumor size was 9.5 cm. The treatment regimen consisted of induction chemotherapy, local treatment, maintenance chemotherapy, and consolidation HDCT based on alkylating agents. No toxic death was observed in the intensive therapy phase. Five-year overall survival and progression-free survival were 63 +/- 7.7% and 47 +/- 7.6%, respectively. Pejorative prognostic factors in this population were metastases at diagnosis (5-year overall survival 34% vs.71%, P = 0.017) and poor pathologic response (5-year overall survival 44% vs.77%, P = 0.03). This retrospective study shows a high long-term survival rate with high-dose chemotherapy in adults.

Abstract
BACKGROUND The objective of this report was to estimate long-term outcome and prognostic factors in children and adolescents who presented with metastatic osteosarcoma at diagnosis. Patients were treated in six French pediatric oncology centers with surgery and multiagent chemotherapy, mainly with high-dose methotrexate. Their medical records were reviewed retrospectively. METHODS The medical records of patients who were treated for metastatic osteosarcoma from 1987 to 2000 were reviewed. Patients were treated with the chemotherapy regimens recommended for nonmetastatic disease in children (the French Society of Pediatric Oncology OS 87 and OS 94 protocols) or, in a few patients, with other chemotherapy regimens. Surgical excision of the primary tumor and, when possible, of all metastatic sites was performed based on a personalized assessment of each patient's situation. RESULTS Seventy-eight patients age < 20 years were treated. Forty-six patients (59%) had only 1 metastatic site (35 to the lungs and 11 to bone). Twenty-eight patients (36%) achieved a complete remission after combination chemotherapy and surgery. The event-free survival and overall survival rates at 5 years were 14% and 19%, respectively. To date, 14 patients (18%) have remained alive with a median follow-up of 112 months. Pretreatment features associated with a shorter event-free survival in the multivariate analysis were metastasis to at least two organs and high alkaline phosphatase level. Patients with at least 1 of these poor prognostic factors had a 2.6% event-free survival rate at 5 years despite treatment. CONCLUSIONS The survival of patients with metastatic osteosarcoma were treated with conventional chemotherapy and surgery remained very poor. Patients should be classified into different prognostic groups and treated accordingly. New therapeutic approaches are warranted to improve the prognosis for patients with the most severe disease.

Abstract
Ewing's sarcoma (ES) initially was believed to be of perivascular endothelial origin. The Ewing's sarcoma family of tumors (EFT) includes ES of bone (ESB), extraosseous ES (EES), peripheral primitive neuroectodermal tumor of bone (pPNET), and malignant small-cell tumor of the thoracopulmonary region, or Askin's tumor, all of which are now known to be neoplasms of neuroectodermal origin. The degree of neuronal differentiation has been used for histopathologic subclassification of the EFT as classical ES (ESB or EES), which is characterized by minimal evidence of neural differentiation, and pPNET, which displays evidence of neural differentiation by standard microscopy, electron microscopy, or immunohistochemistry. Because the behavior, prognosis, and treatment appear to be similar for all subsets of EFT, this histopathologic subclassification may not be clinically significant, though some debate remains whether neural differentiation predicts for inferior outcome.

Abstract
Drug resistance is a major problem in the treatment of solid tumours. Based on a steep dose-response relationship for especially alkylating agents on tumour cell survival, high-dose chemotherapy was considered of interest for the treatment of solid tumours. Results of phase 1 and 2 studies with high-dose chemotherapy in a variety of tumour types showed good response rates. Nowadays, several phase 3 studies are available especially in metastatic and high-risk breast cancer patients. The high expectations of high-dose chemotherapy did not come true. This review analyses results of randomised studies and comments on the discrepancy between findings in patients versus those in tissue culture. Potential factors involved are the presence of tumour stem cells with different characteristics from more mature tumour cells, limitations in drug escalation in the clinic, transplant mortality, trial design and tumour cell contamination of the haematopoietic stem cell transplant. Maturation of the results from recent studies indicating a more modest benefit in, e.g., adjuvant breast cancer balanced versus long-term side effects will ultimately determine the role of high-dose chemotherapy in certain solid tumours. In case of well-defined indications for high-dose chemotherapy, further selection of patients based on patient and tumour characteristics as well as the introduction of new agents will most likely play a role.

Abstract
PURPOSE OF REVIEW The principal pediatric sarcomas are Ewing sarcoma, rhabdomyosarcoma, and osteosarcoma. While the prognosis for these diseases is generally favorable, it is possible to identify groups of patients with each diagnosis whose prognosis remains unacceptably poor. Based on the chemotherapy sensitivity of these tumors, many investigators have suggested that consolidation with high dose chemotherapy with or without radiation therapy followed by stem cell rescue could improve the prognosis for these high risk patients. This review evaluates the results of high dose therapy with stem cell reconstitution used to consolidate treatment of high risk patients with sarcomas. RECENT FINDINGS The majority of the trials which have been conducted to assess this hypothesis have treated relatively small numbers of patients. They do not use consistent definitions of high risk. They have used different regimens for cytoreduction. They have used a variety of sources for stem cells. In many series, the consolidation therapy is applied only to patients who have achieved a significant response to prior therapy and the results have then been compared to a cohort of patients with similar presenting features, not all of whom responded to initial therapy. SUMMARY The published results do not demonstrate an unequivocal benefit for consolidation with high-dose therapy. Future trials of high-dose therapy must define rigorous eligibility criteria, must have an appropriate, preferably randomized, control group, and must be designed with sufficient power to evaluate the hypothesis.

Abstract
Abstract
Osteosarcoma is the most common highly malignant bone tumor with primary appearance during the second and third decade of life. It is associated with a high risk of relapse, possibly resulting from a developed resistance to chemotherapy agents. As a means to overcome osteosarcoma tumor cell resistance and/or to sensitize tumor cells to currently used chemotherapeutic treatments, we examined the role of human apurinic endonuclease 1 (APE1) in osteosarcoma tumor cell resistance and prognosis. Sixty human samples of archived conventional (intramedullary) osteosarcoma were analyzed. APE1 protein was elevated in 72% of these tissues and among those with a known clinical outcome, there was a significant correlation between high APE1 expression levels and reduced survival times. The remaining 28% of samples showed low expression of APE1. Given that APE1 was overexpressed in osteosarcoma, we decreased APE1 levels using silencing RNA (siRNA) targeting technology in the osteosarcoma cell line, human osteogenic sarcoma (HOS), to enhance chemo- and radiation sensitivity. Using siRNA targeted technology of APE1, protein levels were reduced by more than 90% within 24 hours, remained low for 72 hours, and returned to normal levels at 96 hours. There was also a clear loss of APE1 endonuclease activity following APE1-siRNA treatment. A decrease in APE1 levels in siRNA-treated human osteogenic sarcoma cells led to enhanced cell sensitization to the DNA damaging agents: methyl methanesulfonate, H2O2, ionizing radiation, and chemotherapeutic agents. The findings presented here have both prognostic and therapeutic implications for treating osteosarcoma. The APE1-siRNA results demonstrate the feasibility for the therapeutic modulation of APE1 using a variety of molecules and approaches.

Abstract
Children with metastatic retinoblastoma are considered to have a poor prognosis after conventional chemotherapy. We used high-dose chemotherapy (HDC) with peripheral hematopoietic stem cell transplantation in such patients in an attempt to improve their survival. Four patients with bone marrow metastases and one child with extraorbital disease were treated with HDC after achieving complete remission by enucleation and conventional chemotherapy. The child with extraorbital tumor was the only one to receive local irradiation. The conditioning regimen included thiotepa (900 mg/m(2)), etoposide (40 mg/kg) and carboplatin (1.5 g/m(2)) in four patients, and BCNU (300 mg/m(2)), cyclophosphamide (6.8 g/m(2)) and etoposide (1.6 g/m(2)) in one child. Hematologic recovery occurred without delay in all patients. The main toxicities were diarrhea, mucositis and infectious complications. No toxic deaths or any major late toxicities were observed. The child treated with the BCNU regimen developed a meningeal relapse 10 months after HDC, which was partially resected and treated with conventional chemotherapy, but not with radiotherapy. He is in complete remission (CR) 105 months off treatment. The other patients are in CCR for 107, 57, 9 and 8 months after HDC. HDC with thiotepa, etoposide and carboplatin may represent a curative option for children with extrabulbar or disseminated retinoblastoma responsive to chemotherapy. It may control occult CNS disease. The necessity to irradiate these children and the curative potential of this strategy for patients with bulky CNS disease remain to be determined.

Abstract
BACKGROUND This pilot study was undertaken to assess the feasibility, toxicity and response to short-course multiagent chemotherapy followed by high-dose chemotherapy (HDC) in patients with poor prognosis osteosarcoma. PATIENTS AND METHODS A total of 30 patients entered the study. Chemotherapy consisted of four blocks of multiagent chemotherapy administered sequentially over a short period in a dose-intensive manner. This therapy was followed by HDC which consisted of carboplatin at an AUC8 x 3 days, etoposide 400 mg/m(2) x 3 days and cyclophosphamide 60 mg/kg x 2 days. RESULTS A total of 227 cycles of chemotherapy were administered. The main toxicity (for blocks 1-4) was haematological. There were two treatment-related deaths: one post HDC due to sepsis and one during surgery. High-dose chemotherapy was administered to 11 patients (10 with extremity tumours and only one with a pelvic tumour). Twenty-seven patients underwent surgery to the primary. Histological response was assessed in 23 patients. Seven patients (30%) had >90% necrosis. Eight patients underwent pulmonary metastatectomy. The median survival time for the whole group was 16 months. The 2- and 3-year survival rates were 50% and 21% for those with extremity tumours and 19% and 13% for those with axial skeletal tumours. CONCLUSIONS Dose-intensive multiagent chemotherapy though feasible in the group of patients with extremity tumours did not significantly improve the treatment outcome compared with conventional relapse therapy. Inferior survival rates in the axial skeletal group are attributed to less intensive treatment and poor local tumour control.

Abstract
EFT is defined by the expression of ews/ets fusion genes. The type of the fusion transcript impacts on the clinical biology. EFT requires risk adapted treatment. A risk-adapted treatment is determined by tumor localisation, tumor stage and volume. For metastatic and relapsed disease the pattern of spread and the time of relapse are the determinants of risk stratification. Staging of Ewing tumors has been considerably improved by magnetic resonance imaging and modern isotope scanning techniques. However, the determination of the extent of the metastatic spread in particular number of involved bones remains an unresolved issue. The prognosis for high-risk Ewing tumors has been improved by multimodal and high-dose radio/chemotherapy (HDC). The concepts for high-dose therapy in Ewing tumors are based on dose response and dose intensity relationships. In single agent HDC most experience exists with Melphalan. Several chemotherapeutic agents have been used in combination HDC with or without TBI such as Adriamycin, BCNU, Busulphan, Carboplatin, Cyclophosphamide, Etoposide, Melphalan, Thiotepa Procarbazin and Vincristine. To date, superiority of any high-dose chemotherapy regimen has not been established. However, the clinical biology, the pattern of spread and the time of relapse determine the prognosis of patient who are eligible for HDC. In particular, patients with multifocal bone or bone marrow metastases have a poorer prognosis than patients with lung metastases. In addition, patients with a relapse within 24 months have a poorer prognosis than patients with a relapse later than 24 months after diagnosis. This review will analyze the results of single- and multi-agent chemotherapy with respect to agent combination, dose and risk stratum of patient population. Future therapeutic modalities for the treatment of EFT might encompass immunotherapeutic and genetic strategies including allogeneic stem cell transplantation.

Abstract
Soft tissue sarcomas represent a rare and heterogeneous disease. Only few drugs have been identified to be active, with doxorubicin, epirubicin and ifosfamide being the only agents with response rates above 20%. Combination chemotherapy results in higher response rates, however, superiority against single agent chemotherapy in terms of survival has not been established yet. Since a dose-response relationship is suggested for the anthracyclines and especially ifosfamide, high-dose or dose-intensive chemotherapy with bone marrow or stem cell support has been evaluated by several investigators. The studies are usually small, and included a very heterogeneous group of patients. Randomized trials have not been done, so that definite conclusions cannot be drawn to date. High-dose chemotherapy in soft tissue sarcoma has to be considered highly investigational and should not be performed outside clinical trials. Future studies should be focused on the development of active regimens, resulting in complete remission rates, that can be expected to translate into longer survival. Finally, well designed and appropriately powered randomized trials, using established prognostic and predictive factors, should be carried out, preferably in younger patients and in the context of a potentially curative multimodality approach.

Abstract
Topotecan appears to be relatively unaffected by the most common multidrug resistance mechanisms, may potentiate cytotoxicity of alkylators, has good penetration into the central nervous system, is active against a variety of neoplasms, and has myelosuppression as its paramount toxicity. We present our experience with a myeloablative regimen that includes topotecan. Twenty-one patients with poor-prognosis tumors and intact function of key organs received topotecan 2 mg/m2 by 30-min intravenous (i.v.) infusion on days -8, -7, -6, -5, -4; thiotepa 300 mg/m2 by 3 h i.v. infusion on days -8, -7, -6; and carboplatin by 4 h i.v. infusion on days -5, -4, -3 with a daily dose derived from the pediatric Calvert formula, using a targeted area under the curve of seven mg/ml* min ( approximately 500 mg/m2/day). Stem cell rescue was on day 0. The patients were 1 to 29 (median 4) years old; 18 were in complete remission (CR) and three in partial remission (PR). Early toxicities were severe mucositis and erythema with superficial peeling in all patients and a seizure, hypertension, and renal insufficiency followed by veno-occlusive disease in one patient each. Post-transplant treatment included radiotherapy alone (four patients) or plus biological agents (11 patients with neuroblastoma). With a follow-up of 6+ to 32+ (median 11+) months, event-free survivors include 10/11 neuroblastoma patients (first CR), 4/5 brain tumor patients (second PR or CR), 1/3 patients with metastatic Ewing's sarcoma (first or second CR), and a patient transplanted for multiply recurrent immature ovarian teratoma; a patient with desmoplastic small round-cell tumor (second PR) had progressive disease at 8 months. Favorable results for disease control, manageable toxicity, and the antitumor profiles of topotecan, thiotepa, and carboplatin, support use of this three-drug regimen in the treatment of neuroblastoma and brain tumors; applicability to other tumors is still uncertain.

Abstract
PURPOSE To determine whether consolidation therapy with high-dose melphalan, etoposide, and total-body irradiation (TBI) with autologous stem-cell support would improve the prognosis for patients with newly diagnosed metastatic Ewing's sarcoma (ES). PATIENTS AND METHODS Thirty-two eligible patients with newly diagnosed ES metastatic to bone and/or bone marrow were enrolled onto this study. Treatment was initially comprised of five cycles of induction chemotherapy (cyclophosphamide, doxorubicin, and vincristine alternating with ifosfamide and etoposide) and local control. Peripheral-blood stem-cell collection was performed after the second cycle of chemotherapy, with delay if the bone marrow was persistently involved. If patients had a good response to initial therapy, they proceeded to consolidation therapy with melphalan, etoposide, TBI, and stem-cell support. RESULTS Of the 32 eligible patients, 23 proceeded to high-dose therapy consolidation. Of the nine patients who did not proceed to consolidation, four were secondary to progressive disease and two were secondary to toxicity. Three patients died from toxicity during the high-dose phase of the therapy. The majority of the patients who underwent high-dose consolidation therapy experienced relapse and died with progressive disease. Two-year event-free survival (EFS) for all eligible patients is 20%. The 2-year post-stem-cell reconstitution EFS for the subset of 23 patients who received consolidation therapy is 24%. Analysis of peripheral-blood stem-cell collections by molecular techniques for minimal residual disease showed contamination of at least some samples by tumor cells in all three patients with available data. CONCLUSION Consolidation with high-dose melphalan, etoposide, TBI, and autologous stem-cell support failed to improve the probability of EFS in this cohort of patients with newly diagnosed metastatic ES.

Abstract
PURPOSE This review summarizes the published data on the use of high-dose chemotherapy and hematopoietic stem cell rescue (HSCR) in the treatment of recurrent or metastatic rhabdomyosarcoma (RMS). PATIENTS AND METHODS Three hundred eighty-nine patients were identified from 22 articles selected by computer generated searching of MEDLINE (1979-present). One hundred seventy-seven patients had stage 4 disease and were treated during first complete remission (CRI). The remaining patients were treated during CR1/first partial remission (PR1) (110 patients), CR2/PR2 (53 patients), CR2 (12 patients), CR3 (1 patient), or treated with disease (36 patients). RESULTS Patients treated during CR1 or CR1/PR1 had event-free survival (EFS) rates ranging from 24% to 29% at 3 to 6 years from diagnosis and overall survival (OS) rates ranging from 20% to 40% at 2 to 6 years after diagnosis according to data provided as Kaplan-Meier estimates. Studies without Kaplan-Meier estimates (n = 32) indicate that 12 patients (38%) with stage IV RMS treated during CR1 or CR1/PR1 were surviving 7 to 60 months from diagnosis, similar to patients with stage IV RMS treated on Intergroup Rhabdomyosarcoma Studies II or III. Patients treated during CR2, CR3, or with evidence of disease had a worse outcome with an estimated 3 years OS of 12% (n = 51). Studies without Kaplan-Meier estimates (n = 27) indicate that four patients (15%) treated during CR2, CR3, or with disease were surviving 17 to 33 months after transplant. CONCLUSIONS Based on these data, there does not appear to be a significant advantage to undergoing high-dose chemotherapy with HSCR for patients with relapsed or refractory high-risk RMS. Clearly, there is a need for incorporating new treatment strategies for patients with high-risk RMS.

Abstract
In this report, we describe our experience with high-dose chemotherapy (HDC) and autologous stem cell transplantation (ASCT) in 15 children with relapsed osteosarcoma who were treated by members of the Cooperative Osteosarcoma Study Group. Eight patients received HDC after the first relapse, six patients after the second relapse and one after the sixth relapse. Thirteen patients underwent HDC and ASCT in complete remission and two patients had macroscopic tumor residues. Seven patients received HDC based on melphalan and etoposide. Four of these patients were treated with additional carboplatinum. Two patients received carboplatinum, etoposide, and thiotepa or cyclophosphamide. In six patients double HDC was performed. In all six of these, the first HDC consisted of thiotepa/ cyclophosphamide. The second regimens included melphalan/etposide (two patients), melphalan/etposide/ carboplatinum (one patient), and melphalan/busulfan (one patient). Three of the 15 patients died of toxic complications. Eight patients developed further relapses, two patients showed persistent disease, and two patients are presently in continuous complete remission. The probability of relapse-free survival was 0.20 +/- 0.12 within a median follow-up (MFU) of 8 months and the probability of overall survival was 0.29 +/- 0.12 after a MFU of 16 months. In conclusion, utilization of HDC and ASCT in this patient group did not significantly improve the treatment outcome compared to conventional relapse therapy.

Abstract
The prognosis of metastatic malignant mesenchymal tumors (MMT) remains poor. Given the chemosensitivity of these neoplasms, a phase II study of high-dose thiotepa (HDT) was performed to evaluate the efficacy of this drug in this particular subset of pediatric tumors. Between 1986 and 1998, 18 patients, previously treated with conventional therapy for metastatic or refractory MMT, entered the study. Thiotepa was administered at a daily dose of 300 mg/m2 for 3 consecutive days. Hematopoietic stem cell rescue, consisting of bone marrow transplantation or peripheral stem cell transplantation, was performed 2 days after completion of HDT. A response exceeding 50% was observed in 6/18 patients (response rate 33%). Toxicity was severe but never led to death. HDT used at a dose of 900 mg/m2 yields measurable anti-tumor activity in previously treated patients. The next step in these particularly poor prognosis metastatic MMT will be to investigate HDT combined with other drugs, known to be efficient at high doses.

Abstract
PURPOSE We analyzed the clinical features and outcome of patients with radiation-associated osteosarcoma treated during the era of contemporary chemotherapy. PATIENTS AND METHODS The characteristics and outcome of 23 patients (17 males and six females) treated during childhood or adolescence for a solid tumor who later developed osteosarcomas within the radiation field between 1981 and 1996 were reviewed. RESULTS The median dose of radiation delivered to the first cancer was 47 Gy. Nineteen patients also received chemotherapy. The median time between radiotherapy and the diagnosis of secondary osteosarcoma was 8 years. Histologic slide review showed conventional central osteosarcoma with various differentiation patterns in 21 cases, together with one case of high-grade surface osteosarcoma and one of periosteal osteosarcoma. The sites of involvement were the craniofacial bones in six cases, the first cervical vertebra in one, the girdle bones in seven, and the extremities of long bones in nine. Three patients had metastatic disease at the diagnosis of osteosarcoma. Palliative therapy was administered to seven patients. The aim of treatment was curative for 16 patients, two of whom underwent amputation without further therapy. Intensive chemotherapy regimens were administered to 14 patients before and/or after surgery. Fifteen patients achieved complete surgical remission. Twelve patients were alive and disease-free at a median follow-up duration of 7.5 years. Overall and event-free survivals at 8 years were 50% and 41%, respectively. CONCLUSION Patients with radiation-related osteosarcoma and resectable lesions can be cured with surgery and intensive preoperative and postoperative chemotherapy.

Abstract
The ideal cancer therapy would accomodate the specific biology of a tumor and be based upon understanding the mechanisms of malignancy. This vision has been the driving force in cancer research. However, the story of success in clinical cancer management is a story of empirie largely independent from progress in basic research. For the Ewing family of tumors (EFT) comprising Ewing's sarcoma and peripheral primitive neuroectodermal tumor, significant insights into the molecular basis have appeared recently. Some of last year's discoveries may have taken us closer to the identification of the Achilles' heel in this disease. The first clue has been obtained to the mechanism of chromosomal translocation, which constitutes a rate-limiting step in EFT pathogenesis. Also, researchers have progressed in understanding the control of EFT cell proliferation, differentiation, and death. A major role in these processes has been attributed to the EWS-ets gene rearrangement. Specific growth factor circuits appear to be involved in deregulated tumor cell growth. By analogy to heterologous cellular systems, it is possible to postulate an important functional role for CD99(MIC2) as it contributes to the malignant phenotype of EFT. In vitro, as well as the first in vivo, experimental evidence suggests that tumor cell expansion and spread can be counteracted by breaking these physiological pathways. Still, we are far from a tailored biological therapy of EFT. Before this goal may be achieved, we must seek further improvements and diversification of today's standard and intensified treatment regimens.
