Long-Term Follow-up of High-Dose Chemotherapy with Autologous Stem Cell Transplantation in Children and Young Adults with Metastatic or Relapsed Ewing Sarcoma: A Single-Institution Experience. Transplant Cell Ther 2020; 27:72.e1-72.e7. [PMID: 33007495 DOI: 10.1016/j.bbmt.2020.09.029] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2020] [Revised: 08/06/2020] [Accepted: 09/23/2020] [Indexed: 10/23/2022]
Abstract
Forty-seven patients with metastatic disease at diagnosis or recurrent Ewing sarcoma (EWS) received high-dose chemotherapy (HDC) followed by tandem (n = 20, from February 13, 1997, to October 24, 2002) or single (n = 27, from October 1, 2004, to September 5, 2018) autologous hematopoietic stem cell transplantation (ASCT). To our knowledge, this is the largest single-institution study with sustained long-term follow-up exceeding 10 years. All patients who underwent single ASCT received a novel conditioning regimen with busulfan, melphalan, and topotecan. The overall survival (OS) and disease-free survival (DFS) were 46% and 37% at 10 years and 42% and 37% at 15 years, respectively. Disease status at transplant and the time to disease relapse prior to ASCT were identified as important prognostic factors in OS, DFS, and risk of relapse. At 10 years, patients who underwent transplantation in first complete response (1CR) had an excellent outcome (OS 78%), patients in 1CR/second complete response (2CR)/first partial response (1PR) had an OS of 66%, and patients at third or more complete response, second or more partial response, or advanced disease had an OS of 26%. Ten-year OS for patients without a history of relapse, with late relapse (≥2 years from diagnosis), or with early relapse (<2 years from diagnosis) was 75%, 50%, and 18%, respectively. Selected patients in 1CR, 2CR, 1PR, and with late relapse had excellent, sustained 10- and 15-year OS and DFS.

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
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
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
PURPOSE To improve the poor prognosis of patients with primary disseminated multifocal Ewing sarcomas (PDMES) with a dose-intense treatment concept. PATIENTS AND METHODS From 1999 to 2005, 281 patients with PDMES were enrolled onto the Euro-EWING 99 R3 study. Median age was 16.2 years (range, 0.4 to 49 years). Recommended treatment consisted of six cycles of vincristine, ifosfamide, doxorubicin, and etoposide (VIDE), one cycle of vincristine, dactinomycin, and ifosfamide (VAI), local treatment (surgery and/or radiotherapy), and high-dose busulfan-melphalan followed by autologous stem-cell transplantation (HDT/SCT). RESULTS After a median follow-up of 3.8 years, event-free survival (EFS) and overall survival (OS) at 3 years for all 281 patients were 27% +/- 3% and 34% +/- 4% respectively. Six VIDE cycles were completed by 250 patients (89%); 169 patients (60%) received HDT/SCT. The estimated 3-year EFS from the start of HDT/SCT was 45% for 46 children younger than 14 years. Cox regression analyses demonstrated increased risk at diagnosis for patients older than 14 years (hazard ratio [HR] = 1.6), a primary tumor volume more than 200 mL (HR = 1.8), more than one bone metastatic site (HR = 2.0), bone marrow metastases (HR = 1.6), and additional lung metastases (HR = 1.5). An up-front risk score based on these HR factors identified three groups with EFS rates of 50% for score <or= 3 (82 patients), 25% for score more than 3 to less than 5 (102 patients), and 10% for score >or= 5 (70 patients; P < .0001). CONCLUSION PDMES patients may survive with intensive multimodal therapy. Age, tumor volume, and extent of metastatic spread are relevant risk factors. A score based on these factors may facilitate risk-adapted treatment approaches.

Abstract
The aim of this retrospective study was to analyze the outcome and identify risk factors associated to progression-free survival (PFS) in 47 children with high-risk Ewing sarcoma who underwent autologous peripheral blood stem cell (PBSC) transplantation in the authors' institution between 1995 and 2009. The conditioning regimen used in all patients consisted of high dose of busulfan and melphalan. Median age was 13 years (range: 4-21 years). Forty-three percent of patients had metastases at diagnosis. The probability of transplant-related mortality (TRM) was 6% +/- 3%. Recurrence/progressive disease was observed in 17 patients. The probability of recurrence/progression was 39% +/- 7%. With a median follow-up of 92 months (range: 6-168 months), the PFS was 56% +/- 4% for the whole group. In multivariate analysis, localized disease at diagnosis and obtaining complete remission (CR) by 3 months after transplantation were variables associated to better outcomes. The probability of PFS was 78% +/- 8% and 27% +/- 10% for patients with localized and metastatic disease at diagnosis, respectively (P = .0001). This retrospective study shows a high long-term survival using high dose of busulfan and melphalan as conditioning regimen in children with high-risk Ewing tumors. Patients with localized disease at diagnosis and those with good response to treatment before or after transplant would benefit most.

Abstract
Curcumin is a naturally occurring polyphenolic compound found in the turmeric, which is used as food additive in Indian cooking and as a therapeutic agent in traditional Indian medicine. Curcumin is currently under investigation as a chemotherapeutic and chemopreventive agent in adult cancer models at both pre-clinical and clinical levels. In this preliminary study, we show that curcumin is effective in causing cell cycle arrest, inducing apoptosis, and suppressing colony formation in the Ewing sarcoma cell line SK-NEP-1. Curcumin causes upregulation of cleaved caspase 3 and downregulation of phospho-Akt, producing apoptosis in Ewing sarcoma cells at an inhibitory concentration 50% (IC50) of approximately 4 μM. Our findings indicate a need for further evaluation of curcumin in chemotherapy and chemoprevention of Ewing sarcoma.

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's sarcoma cells are highly susceptible to apoptosis via tumor necrosis factor apoptosis-inducing ligand (TRAIL). Resistance to TRAIL has been linked to deficient expression of caspase-8 in vitro. Here, we report on the status of caspase-8 expression in tumors from patients with Ewing's sarcoma, the effect of interferon-gamma on caspase-8 expression and apoptosis, and the role of caspase-8 for TRAIL- and chemotherapy-mediated apoptosis in Ewing's sarcoma. Using immunohistochemistry, we show that low expression of caspase-8 is seen in about 24% of tumors. Interferon-gamma induces expression of caspase-8 at concentrations achievable in humans and sensitizes cells to TRAIL. Transfection of wild type but not mutant caspase-8 into caspase-8-deficient Ewing's sarcoma cells restored sensitivity to TRAIL, indicating that up-regulation of caspase-8 is sufficient to restore TRAIL sensitivity. In contrast, no role for caspase-8 in chemotherapy-induced apoptosis was identified, because 1) transfection of caspase-8 or treatment with interferon-gamma did not alter the sensitivity of caspase-8-deficient cells to chemotherapeutics, 2) application of chemotherapy did not select for caspase-8-negative tumor cells in vivo, and 3) the caspase-8 status of tumors did not influence survival after chemotherapy-based protocols. In conclusion, our data provide a rationale for the inclusion of interferon-gamma in upcoming clinical trials with TRAIL.

Abstract
The treatment of small-round-cell tumors (SRCT) in adult patients remains a challenge to clinicians. In the present study, we analyzed the feasibility and efficacy of high-dose chemotherapy (HDCT) followed by autologous peripheral blood stem-cell rescue as a consolidation therapy exclusively for patients with good disease control through a single regimen of induction chemotherapy and local therapy. Twenty-one patients (12 females, median age 22.0 years) were analyzed, including seven cases with rhabdomyosarcoma (RMS) and 14 cases with Ewing's family tumors (EFT). Overall, survival was 46% and failure-free survival (FFS) was 33% at 3 years. Patients with EFT had better FFS than those with RMS, with an estimated 3-year FFS of 50% (P<0.01). There was a single case of possible treatment-related death and two cases of secondary malignancies. This study cannot conclusively determine the beneficial effects of HDCT for improving treatment outcomes in adult SRCTs due to the small number of subjects. However, study findings suggest that a subgroup of patients with EFT may obtain prolonged survival benefits from this therapy.

Abstract
Ewing's sarcoma is the second most frequent primary bone cancer, with approximately 225 new cases diagnosed each year in patients less than 20 years of age in North America. It is one of the pediatric small round blue cell tumors, characterized by strong membrane expression of CD99 in a chain-mail pattern and negativity for lymphoid (CD45), rhabdomyosarcoma (myogenin, desmin, actin) and neuroblastoma (neurofilament protein) markers. Pathognomonic translocations involving the ews gene on chromosome 22 and an ets-type gene, most commonly the fli1 gene on chromosome 11, are implicated in the great majority of cases. Clinical presentation is usually dominated by local bone pain and a mass. Imaging reveals a technetium pyrophosphate avid lesion that, on plain radiograph, is destructive, diaphyseal and classically causes layered periosteal calcification. Magnetic resonance best defines the extent of the lesion. Biopsy should be undertaken by an experienced orthopedic oncologist. Approximately three quarters of patients have initially localized disease. About two thirds survive disease-free. Management, preferably at a specialist center with a multi-disciplinary team, includes both local control-either surgery, radiation or a combination-and systemic chemotherapy. Chemotherapy includes cyclic combinations, incorporating vincristine, doxorubicin, cyclophosphamide, etoposide, ifosfamide and occasionally actinomycin D. Topotecan in combination with cyclophosphamide has shown preliminary activity. Patients with initially metastatic disease fare less well, with about one quarter surviving. Studies incorporating intensive therapy followed by stem cell infusion show no clear benefit. New approaches include anti-angiogenic therapy, particularly since vascular endothelial growth factor is an apparent downstream target of the ews-fli1 oncogene.

Abstract
PURPOSE To improve the prognosis for patients with metastatic Ewing sarcoma/primitive neuroectodermal tumors (ES/PNET) using conventional chemotherapy and consolidation high-dose chemotherapy (HDCT) containing busulfan and melphalan. PATIENTS AND METHODS Ninety-seven unselected patients with newly diagnosed metastatic ES/PNET received induction chemotherapy that included five cycles of cyclophosphamide 150 mg/m2/d for 7 days, doxorubicin 35 mg/m2/d once, followed by two cycles of ifosfamide 1.8 g/m2/d for 5 days, and etoposide 100 mg/m2/d for 5 days. Patients in complete or very good partial remission received HDCT with busulfan total dose 600 mg/m2 and melphalan 140 mg/m2 followed by autologous blood stem cells. Local therapy (surgery and/or radiation therapy) was performed before or after HDCT. RESULTS Ninety-seven patients were enrolled from 1991 to 1999 (median age, 12.3 years; range, 0.2 to 25 years). Among them, 75 received HDCT. The 5-year event-free survival (EFS) rate for all 97 patients was 37% and the overall survival (OS) rate was 38%. The EFS after HDCT was 47%. The EFS for the 44 patients with lung-only metastases was 52%, whereas it was 36% for patients with bone metastases without bone marrow involvement. Among the 23 patients with bone marrow metastases, only one survived. The multivariate analysis for both EFS and for OS identified three independent prognostic factors: age, fever at diagnosis, and bone marrow involvement. CONCLUSION Compared with conventional chemotherapy, HDCT may yield benefits for patients with lung-only metastases or bone metastases. These results warrant confirmation in a randomized trial and provide part of the background data for the ongoing Euro-Ewing study.

Abstract
PURPOSE Despite the availability of combined-modality treatment for Ewing sarcoma (ES) and soft tissue sarcomas (STS), results from independent groups still indicate a poor prognosis for high-risk and metastasized patients. The benefit of high-dose chemotherapy (HDCT) with autologous peripheral blood stem cell transplantation (ASCT) as compared to standard treatment is not defined. METHODS Here, we report of HDCT in 35 consecutive adult patients with poor-risk ES or rhabdomyosarcoma (n = 11) and STS (n = 24) undergoing ASCT between July 1992 and March 2003. At a median follow-up of 100.6 months after ASCT, 11 patients are alive, with nine in sustained complete remission (CR) and each one in partial remission (PR) and stable disease. Median overall survival (OS) from ASCT was 17.1 months. Response to pretreatment, Karnofsky index > 80%, R (0) resection and first-line ASCT were associated with long-term OS (p < 0.05). CONCLUSION These data indicate that (1) patients achieving a CR or PR following induction, with preserved performance status and R (0) resection may benefit from ASCT and (2) that this can be an useful therapeutic modality in a subset of patients, in some achieving remarkable responses.

Abstract
BACKGROUND The outcome for patients with recurrent or progressive Ewing's sarcoma family of tumours (ESFT) is poor. High dose therapy (HDT) has been used for a number of years in an attempt to improve survival; however, evidence for the efficacy of this treatment remains limited. PATIENTS AND METHODS Between 1992 and 2004, 33 patients with recurrent or progressive ESFT were treated with HDT with bone marrow (n=2), peripheral blood stem cell (n=30), or bone marrow and peripheral blood stem cell support (n=1), at a single institution. HDT was with busulphan and melphalan in 22 patients; melphalan and etoposide in seven patients, three with total body irradiation (TBI); melphalan in three patients (2 with TBI), and busulphan and cyclophosphamide in one patient. RESULTS The 2 and 5 year event free survival was 42.5% (95% CI, 26-59%) and 38.2% (95% CI, 21-55%) respectively. There was one treatment related death from colitis, and grade 4 infection was observed in two patients. CONCLUSIONS Long-term survival can be attained in patients with recurrent or refractory ESFT treated with HDT. However, this treatment is associated with severe toxicity. A need remains for prospective randomised clinical trials of HDT in this group of patients.

Abstract
BACKGROUND Ewing sarcoma (ES) and extraosseous ES/primitive neuroectodermal tumors (PNET) share histopathologic features of the ES family of tumors (ESFT). The authors report on their results from a regimen of ifosfamide, carboplatin, and etoposide (ICE) with cyclophosphamide, doxorubicin, and vincristine (CAV) dose intensification in patients with high-risk ESFT. METHODS Since 1990, patients with ESFT and with 1 or more of the following risk factors were reviewed: tumor volume > 200 mL, tumor site with a poor prognosis, and pulmonary and/or bone marrow metastases. RESULTS Thirty-six patients with ESFT who were involved in the study were divided into 2 arms of 18 patients each. One group received treatment with various regimens, and the other group received treatment with ICE plus CAV. The disease was brought under control more rapidly in the latter patients, for whom surgery was more easily feasible, and up to 90% of patients achieved a major response, with an estimated 3-year overall survival rate of 67% +/- 12%. CONCLUSIONS The current results showed that ICE plus CAV was tolerated well and was effective in the studied subset of tumors, indicating that dose intensification correlates with better disease control, a high percentage of necrosis, and conservative surgery in patients with high-risk ESFT.

Abstract
The Ewing's sarcoma family of tumors are malignant tumors of bone and soft tissue which occur predominantely in children and adolescents. Whereas cure rates for patients with localized tumors are around 70%, survival rates for patients with metastases or relapse are poor in spite of intensive chemo- and radiation therapy, demonstrating a clear need for new, more effective therapies. Insights into the biology of the tumors of the Ewing's sarcoma family with identification of the EWS/ETS gene rearrangement as the key event in malignant transformation and its influence on the regulation of various pathways involved in proliferation, differentiation and apoptosis has led to the identification of potential targets for the development of new molecular therapeutics. This review will focus on the regulation of major pathways of proliferation and apoptosis in tumors of the Ewing's sarcoma family and point out how modulation of these pathways might be of potential use for future therapy.

Abstract
Ewing's sarcoma is the second most common primary bone tumor seen in children and adolescents, and was described by James Ewing in 1921 as a diffuse endothelioma of bone. It is one of the differential diagnoses of pediatric small round blue cell tumors. This is not a single condition, but a group of morphologically and clinically closely related disorders with similar molecular biology -- expression of tumor-specific chimeric oncoproteins through balanced chromosomal translocations involving the EWS gene -- often referred to as the Ewing family of tumors. This includes Ewing's sarcoma of bone, extra-osseous Ewing's sarcoma, Askin tumor and peripheral neuroectodermal tumor. These are aggressive neoplasms with almost 25% of patients having clinically evident metastases at presentation. Ewing's sarcoma has therefore been considered as a systemic disease necessitating local as well as systemic treatment. An aggressive multidisciplinary approach has resulted in significant improvement in prognosis for patients with these tumors. Despite aggressive treatment, 20-40% of patients with localized disease and almost 80% of patients with metastatic disease at presentation succumb to the illness. Advances in understanding the molecular biology of these tumors will hopefully result in the development of novel treatment approaches. The aim of this article is to review the existing treatment methods and to highlight the more recent approaches to the treatment of this condition.

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
Total body radiation (TBI) has been used for many years as a preconditioning agent before bone marrow transplantation. Many side effects still plague its use. We investigated the planning and delivery of total body irradiation (TBI) and selective total marrow irradiation (TMI) and a reduced radiation dose to sensitive structures using image-guided helical tomotherapy. To assess the feasibility of using helical tomotherapy, (A) we studied variations in pitch, field width, and modulation factor on total body and total marrow helical tomotherapy treatments. We varied these parameters to provide a uniform dose along with a treatment times similar to conventional TBI (15-30 min). (B) We also investigated limited (head, chest, and pelvis) megavoltage CT (MVCT) scanning for the dimensional pretreatment setup verification rather than total body MVCT scanning to shorten the overall treatment time per treatment fraction. (C) We placed thermoluminescent detectors (TLDs) inside a Rando phantom to measure the dose at seven anatomical sites, including the lungs. A simulated TBI treatment showed homogeneous dose coverage (+/-10%) to the whole body. Doses to the sensitive organs were reduced by 35%-70% of the target dose. TLD measurements on Rando showed an accurate dose delivery (+/-7%) to the target and critical organs. In the TMI study, the dose was delivered conformally to the bone marrow only. The TBI and TMI treatment delivery time was reduced (by 50%) by increasing the field width from 2.5 to 5.0 cm in the inferior-superior direction. A limited MVCT reduced the target localization time 60% compared to whole body MVCT. MVCT image-guided helical tomotherapy offers a novel method to deliver a precise, homogeneous radiation dose to the whole body target while reducing the dose significantly to all critical organs. A judicious selection of pitch, modulation factor, and field size is required to produce a homogeneous dose distribution along with an acceptable treatment time. In addition, conformal radiation to the bone marrow appears feasible in an external radiation treatment using image-guided helical tomotherapy.

Abstract
Purpose The overall survival (OS) of patients with relapsed Ewing’s sarcoma family of tumors (ESFT) is poor, and the relative benefit of high-dose therapy (HDT) is controversial. Patients and Methods We retrospectively identified 55 consecutive ESFT patients with adequate medical records for review, who were treated at Children’s Hospital and Regional Medical Center and who developed disease recurrence between January 1, 1985 and December 31, 2002. Results The median relapse-free interval (RFI) from diagnosis to first recurrence was 17 months (range, 5 to 90 months). Most recurrences were metastatic only (39 patients) or local and metastatic (10 patients). Twenty-seven patients (49%) achieved a partial or complete response to second-line treatment, with a median duration of response of 27 months (range, 5 to 119+ months). The 5-year OS rate for all relapsed patients was 23% (95% CI, 11% to 35%). By univariate analysis, improved OS was associated with response to second-line treatment versus no response (46% v 0%, respectively; P < .0001), RFI ≥ 24 months versus less than 24 months (48% v 12%, respectively; P = .0001), and no metastases at initial diagnosis versus presence of metastases (31% v 12%, respectively; P = .05). Because all 13 patients who received HDT also had responsive relapse, we performed a multivariate analysis. Reduced risk of death was associated with response to second-line therapy (relative risk, 0.14; 95% CI, 0.05 to 0.40), RFI ≥ 24 months (relative risk, 0.29; 95% CI, 0.13 to 0.66), and receiving HDT (relative risk, 0.26; 95% CI, 0.08 to 0.85). Conclusion HDT as consolidation therapy for relapsed ESFT seems to be associated with improved OS, even after adjusting for RFI and response to second-line treatment.

Abstract
BACKGROUND: The role of high dose therapy (HDT) with autologous stem cell transplantation (AuSCT) for the treatment of bone and soft tissue sarcomas remains investigational. There are few reports examining this strategy focusing on the adult population. METHODS: We retrospectively reviewed our experience of adult patients undergoing HDT and AuSCT for 'paediatric' sarcomas. RESULTS: A total of 17 patients (14 male, 3 female) with median age at transplant of 24 years (range 20 - 41) were identified. The diagnosis was Ewings sarcoma/PNET (10), osteosarcoma (5) and rhabdomyosarcoma (2). Status prior to HDT, following conventional-dose chemotherapy +/- surgery +/- radiotherapy, was complete remission (CR) (6), partial remission (PR) (6), stable disease (1) and progressive disease (4). There was no transplant-related mortality. Two patients remain disease free beyond four years and both received HDT as part of their primary therapy (CR1 and PR1) however, the median progression free survival and overall survival following AuSCT for the entire cohort was only 7 months (range: 2-92 months) and 13 months (range: 2 - 92 months), respectively. CONCLUSION: HDT and AuSCT infrequently achieves prolonged remissions in adult patients and should only be considered in patients who are in a PR or CR following conventional-dose therapy. Further studies are required to define the role of HDT with AuSCT for adult patients with sarcoma.

Abstract
Although a multimodal approach consisting of chemotherapy and local control with surgery and/or radiation has improved survival in children with Ewing's sarcoma family of tumors, the prognosis for patients with high-risk disease remains poor. More aggressive treatments with high-dose myeloablative chemotherapy followed by stem cell rescue have been utilized in an attempt to improve survival in these patients. Although many studies have been published, it is difficult to interpret the data since patient populations were heterogeneous with respect to disease stage, prior therapy, conditioning and stem cell source. Furthermore, there was no uniform definition of high risk, the sample sizes were small and most studies lacked appropriate control groups. Assessment of the utility of megatherapy will require prospective controlled studies.

Abstract
This review will focus primarily on own recent work on the treatment of advanced Ewing tumors (AETs) and will attempt, in addition, to give a comprehensive overview of novel developments. The field under review has been shaped by investigators from both Europe and the United States of America in a scientific debate evolving over more than a decade at the meetings of the International Society of Pediatric Oncology and other scientific meetings. In the light of this debate, most oncologists will agree that patients with AETs are facing the worst prognosis of all patients with this disease and include both: (i) patients with primary metastatic disease with the worst prognosis as well as (ii) patients with relapse with the worst prognosis. The contributions of various investigators have lead to the identification of specific risk stratification criteria to overcome the heterogeneity of patients within the conventionally defined clinical stages of localized metastatic and relapsed disease. This review will address the following issues of treatment of AETs: (i) a definition of AET; (ii) risks and benefits of allogeneic vs. autologous stem cell transplantation; (iii) the role of total body irradiation; (iv) the number of involved bones as a risk factor in multifocal bone disease in AET; (v) the development of immunogene therapy in AET; (vi) the matching of radiochemo- and immunotherapy in AET; (vii) the future perspective of functional genomics and targeted therapy.

Abstract
PURPOSE To improve the long-term event-free survival of patients with Ewing's family of tumors (EFTs) using high-dose, short-term chemotherapy. PATIENTS AND METHODS P6 was a prospective study of previously untreated patients with newly diagnosed EFTs. Patients received seven cycles of chemotherapy. Cycles 1, 2, 3, and 6 consisted of cyclophosphamide 2,100 mg/m2/d on days 1 and 2, and a 72-hour continuous infusion of doxorubicin 75 mg/m2 and vincristine 2 mg/m2 starting day 1. Cycles 4, 5, and 7 consisted of 5 consecutive days of ifosfamide 1,800 mg/m2/d and etoposide 100 mg/m2/d. RESULTS Sixty-eight patients were enrolled from 1991 to 2001 (median age, 18.7 years; range, 3.7 to 39.9 years). At diagnosis, 44 patients had local-regional disease, and 24 had distant metastases. The 4-year event-free survival (EFS) rate for patients with local-regional disease is 82%; overall survival (OS) is 89%. The 4-year EFS rate for patients with distant metastases is 12%; the OS rate is 17.8%. All events occurred within 51 months of diagnosis. Four patients with distant metastases had progressive disease during therapy, and no patient with local-regional disease experienced disease progression during therapy. CONCLUSION Sustained EFS and OS can be achieved with intensive chemotherapy in children and young adults with local-regional EFTs. This therapy is relatively ineffective in the treatment of metastatic EFTs.

Abstract
PURPOSE Risk stratification of metastatic and relapsed Ewing's tumors (ETs) has been a matter of debate during the last decade. Patients with bone or bone marrow metastases or early or multiple relapses constitute the worst risk group in ET and have a poorer prognosis than patients with primary lung metastases or late relapses. In this article, the results of the present Meta European Intergroup Cooperative Ewing Sarcoma Study (MetaEICESS) (tandem melphalan/etoposide [TandemME]) were compared with the result of the previous study (hyper melphalan/etoposide [HyperME]), both at 5 years, in a patient population within the same high-risk stratum to determine toxicity. PATIENTS AND METHODS Among 54 eligible patients, 26 were treated according to the HyperME protocol, and 28 were treated according to TandemME protocol. Patients received six cycles of the Cooperative Ewing Sarcoma Study treatment in HyperME and six cycles of the EICESS treatment in TandemME as induction chemotherapy. Patients also received involved-compartment irradiation for local intensification and myeloablative systemic intensification consolidation with hyperfractionated total-body irradiation (TBI) combined with melphalan/etoposide in HyperME or two times the melphalan/etoposide in TandemME followed by autologous stem-cell transplantation. RESULTS The event-free survival (EFS) rate +/- SD in HyperME and TandemME was 22% +/- 8% and 29% +/- 9%, respectively. The dead of complication rate was 23% in HyperME and 4% in TandemME. CONCLUSION TandemME offers a decent, albeit still not satisfactory, rate of long-term remissions in most advanced ETs (AETs), with short-term treatment and acceptable toxicity. TBI was not required to maintain EFS level in this setting but was associated with a high rate of toxic death. Future prospective studies in unselected patients are warranted to evaluate high-dose therapy in an unselected group of patients with AET.

Abstract
BACKGROUND Survival after relapse in patients with Ewing sarcoma is very poor and this retrospective study attempts to identify of prognostic factors predicting survival after relapse. PROCEDURE A total of 191 patients with localised Ewing sarcoma were registered in the ET-2 trial of the United Kingdom Children's Cancer Study Group (UKCCSG). All patients received standardised primary treatment with chemotherapy and surgery and or radiotherapy as local modality treatment. Sixty-four patients who relapsed are included in this report. Treatment at relapse was variable and included chemotherapy, surgery, radiotherapy and high dose therapy (HDT) or megatherapy with peripheral stem cell transplantation (PBSCT) or autologous bone marrow transplantation (ABMT) in various combinations. A subgroup of patients had only non-specific symptomatic treatment at relapse. Both univariate and multivariate methods were used to investigate variables affecting survival after relapse. RESULTS The overall actuarial median survival from relapse for all patients was 14 months (95% CI 11-16 months). Univariate analysis showed that males had a longer survival (median, 16 months vs. 11 months); patients who relapsed while on treatment did worse (median, 3 months vs. 16 months) and patients who had a longer disease-free interval (DFI) prior to relapse had a better outcome (DFI <1 year, median survival = 3 months; DFI 1-2 years, survival = 8 months; DFI > 2 years, median survival = 24 months, P < 0.001). Multivariate analysis confirmed that duration of first remission was the only factor associated with longer survival after relapse. CONCLUSIONS These data suggest that although aggressive therapy may delay disease progression after relapse for some children, the course of the disease after relapse is usually fatal. International co-operative studies are needed to evaluate new strategies.

Abstract
The use of high-dose chemotherapy followed by autologous HCT and the use of allogeneic HCT in children and adolescents with high-risk ALL, AML, and NBL has successfully improved outcomes. For other diseases, however, the role of HCT in treatment remains a subject of further research. The availability of HCT was significantly expanded by developing alternative graft sources that currently include BM, peripheral blood, and UCB from autologous and allogeneic related or unrelated donors. Progress in autologous HCT has been achieved by the identification of more effective and less toxic preparative regimens and by ex vivo purging of stem cell products. In allogeneic HCT, graft-versus-leukemia or graft-versus-tumor effects are being exploited increasingly to lower relapse rates. In addition, immunomodulation to promote tolerance, as well as allogeneic antitumor reactions have been achieved by antibody therapy, cytokine therapy, or cell-based immunotherapy. Future improvements are likely, as evidenced by promising preliminary results in the development of stem cell collection techniques, in vitro stem cell expansion, and purging techniques of stem cell grafts. The development of less intensive or nonmyeloablative preparative regimens may further reduce regimen-related morbidity and mortality Specific immunotherapy may facilitate tolerance induction in mismatched allogeneic HCT and support allogeneic HCT in the setting of donor-host HLA disparity. Ultimately, advances in cytokine therapy, tumor-specific vaccines, and gene therapy may decrease or even eradicate recurrence of the malignant disease after HCT.

Abstract
Although the overall results of treatment of Ewing's tumors have improved, patients with high-risk factors, including metastatic disease at diagnosis, bulky primary tumors, axial sites, and age >15 years, continue to have poor prognoses. The effects of high-dose chemotherapy and autologous peripheral blood stem-cell transplantation on high-risk Ewing's tumor patients have been reported. In most of these studies, conditioning and high-dose regimens varied among patients. Here we report the feasibility and effects of a high-dose chemotherapy regimen conducted in our institution. Seven patients with high-risk Ewing's tumors were treated by high-dose chemotherapy. The patients received four cycles of remission induction chemotherapy, and then peripheral blood stem cells were mobilized by high-dose etoposide and harvested. Myeloablative chemotherapy consisted of carboplatin, ifosfamide, and etoposide. The patients have 5-year overall and relapse-free survival probabilities of 0.86 and 0.81, respectively. The results were significantly better than those for patients treated with conventional chemotherapy alone. None of the patients had severe side effects. The high-dose regimen and transplantation were feasible and well tolerated. The poor prognoses of high-risk Ewing's tumor patients may be improved by high-dose chemotherapy with peripheral blood stem cell transplantation. However, the real impact of the therapy on the clinical outcome of patients with high-risk Ewing's tumors should be evaluated in a prospective, randomized study.

Abstract
Ewing tumours, i.e. Ewing's sarcoma and malignant peripheral neuroectodermal tumours, are the second most common primary malignant tumours of bone in childhood and adolescence, with an annual incidence rate in Caucasians of 3 per 1 million children <15 years of age. Histopathologically small blue round cell tumours, Ewing tumours show a typical chromosomal rearrangement in >95% of cases linking the EWS gene on chromosome 22q12 to a member of the ETS transcription gene family, most commonly to Fli-1 on 11q24. This fusion contributes to the malignant potential of Ewing tumour cells, indeed antisense oligonucleotides may prevent tumour growth in vitro. After open biopsy, and histological and possibly molecular biological confirmation of the diagnosis, treatment consists of several months of multidrug cytostatic therapy and local therapy. Both surgery and radiotherapy may control local disease, but without consequent cytostatic chemotherapy all patients will eventually succumb to distant metastases. With the use of alkylating agents including doxorubicin, cyclophosphamide and/or ifosfamide, and other cytostatic drugs such as actinomycin D (dactinomycin), vincristine and etoposide, long-term survival can be achieved in >50% of patients with localised disease. Patients with clinically detectable metastases at diagnosis, patients not responding to therapy and patients with disease relapse have a significantly poorer prognosis. Maximum supportive care and local therapy managed by an experienced physician are required in all patients, and inclusion of high-risk patients in phase I and II studies is warranted. Hence, treatment of patients with Ewing tumours should be performed in experienced centres only and preferably within controlled clinical trials.

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
PURPOSE Attempts to improve outcomes of patients with Ewing's sarcoma/primitive neuroectodermal tumor (ES/PNET) metastatic to bone/bone marrow (BM) have focused on chemotherapy dose intensification strategies. We now present results achieved with that approach, as carried out at Memorial Sloan-Kettering Cancer Center (MSKCC) and as reported in the literature. PATIENTS AND METHODS Twenty-one unselected MSKCC patients with newly diagnosed ES/PNET metastatic to bone/BM received the "P6" protocol which includes cycles of cyclophosphamide (4.2 g/m(2))/doxorubicin (75 mg/m(2))/vincristine and cycles of ifosfamide (9 g/m(2))/etoposide (500 mg/m(2)). Patients in complete/very good partial remission (CR/VGPR) after P6 received myeloablative therapy with either total-body irradiation (TBI) (hyperfractionated 15 Gy)/melphalan (180 mg/m(2)) or thiotepa (900 mg/m(2))/carboplatin (1,500 mg/m(2)). We reviewed the literature. RESULTS Only one MSKCC patient became a long-term event-free survivor; all but one relapse was in a distant site. Initial responses to P6 were CR/VGPR in 19 patients, but eight of them plus two others developed PD while receiving or shortly after completing P6. Eight patients were treated with TBI/melphalan: four relapsed 2 to 7 months after transplantation; two died early of toxicity; one died of pulmonary failure 17 months after transplantation (no evidence of ES/PNET); and one remains in CR at more than 7 years. The three patients treated with thiotepa/carboplatin relapsed 3 to 4 months after transplantation. All reports on large series of unselected patients with ES/PNET metastatic to bone/BM showed similarly unsatisfactory results. Poor outcome was seen with use of active agents for ES/PNET-cyclophosphamide, ifosfamide, doxorubicin, dactinomycin, vincristine, etoposide - at standard dosages for prolonged periods of time and at higher dosages in intensive regimens for short or prolonged periods of time. No improvements in event-free survival rates occurred with successive cooperative group or large single-institutional studies that used increasingly aggressive chemotherapeutic approaches. Inclusion of ifosfamide with or without etoposide made no difference nor did consolidation of remission with myeloablative chemoradiotherapy. Secondary leukemia emerged as a major risk with dose-intensive regimens. CONCLUSION The MSKCC experience and findings reported in the literature suggest that dose-intensive use of the chemotherapy agents with established activity against ES/PNET is reaching its efficacy and toxicity limits. A major impact on prognosis awaits the development of entirely novel therapies.
