Novel Strategy Involving High-Dose Chemotherapy with Stem Cell Rescue Followed by Intrathecal Topotecan Maintenance Therapy without Whole-Brain Irradiation for Atypical Teratoid/Rhabdoid Tumors. Pediatr Hematol Oncol 2023; 40:629-642. [PMID: 37519026 DOI: 10.1080/08880018.2023.2220734] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/06/2023] [Revised: 05/04/2023] [Accepted: 05/30/2023] [Indexed: 08/01/2023]
Abstract
Atypical teratoid/rhabdoid tumor (AT/RT) is a rare aggressive central nervous system tumor that typically affects children under three years old and has poor survival with a high risk for neurologic deficits. The primary purpose of this study was to successfully treat the disease and delay or avoid whole-brain radiotherapy for children with AT/RT. A retrospective analysis was performed for six children diagnosed with AT/RT and treated with multimodal treatment at a single institute between 2014 and 2020. Furthermore, germline SMARCB1 aberrations and MGMT methylation status of the tumors were analyzed. One patient who did not receive a modified IRS-III regimen replaced with ifosphamide, carboplatin, and etoposide (ICE) in induction chemotherapy was excluded from this analysis. Five patients who received ICE therapy were under three years old. After a surgical approach, they received intensive chemotherapy and high-dose chemotherapy with autologous peripheral blood stem cell transplantation (HDCT/autoPBSCT) followed by intrathecal topotecan maintenance therapy. Three patients underwent single HDCT/autoPBSCT, and the other two received sequential treatment. Two patients with germline SMARCB1 aberrations and metastases died of progressive AT/RT or therapy-related malignancy, while 3 with localized tumors without germline SMARCB1 aberrations remained alive. One survivor received local radiotherapy only, while the other two did not undergo radiotherapy. All three surviving patients were able to avoid whole-brain radiotherapy. Our results suggest that AT/RT patients with localized tumors without germline SMARCB1 aberrations can be rescued with multimodal therapy, including induction therapy containing ICE followed by HDCT/autoPBSCT and intrathecal topotecan maintenance therapy without radiotherapy. Further large-scale studies are necessary to confirm this hypothesis.

Feasibility and Toxicity of Interval-Compressed Chemotherapy in Asian Children and Young Adults with Sarcoma. J Pers Med 2023; 13:jpm13040668. [PMID: 37109054 PMCID: PMC10146212 DOI: 10.3390/jpm13040668] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2023] [Revised: 03/09/2023] [Accepted: 03/20/2023] [Indexed: 04/29/2023] Open
Abstract
Twelve Asian patients with sarcoma received interval-compressed (ic-) chemotherapy scheduled every 14 days with a regimen of vincristine (2 mg/m2), doxorubicin (75 mg/m2), and cyclophosphamide (1200-2200 mg/m2) (VDC) alternating with a regimen of ifosfamide (9000 mg/m2) and etoposide (500 mg/m2) (IE), with filgrastim (5-10 mcg/kg/day) between cycles. Carboplatin (800 mg/m2) was added for CIC-rearranged sarcoma. The patients were treated with 129 cycles of ic-VDC/IE with a median interval of 19 days (interquartile range [IQR], 15-24 days. Median nadirs (IQR) were neutrophil count, 134 (30-396) × 106/L at day 11 (10-12), recovery by day 15 (14-17) and platelet count, 35 (23-83) × 109/L at day 11 (10-13), recovery by day 17 (14-21). Fever and bacteremia were observed in 36% and 8% of cycles, respectively. The diagnoses were Ewing sarcoma (6), rhabdomyosarcoma (3), myoepithelial carcinoma (1), malignant peripheral nerve sheath tumor (1), and CIC-DUX4 Sarcoma (1). Seven of the nine patients with measurable tumors responded (one CR and six PR). Interval-compressed chemotherapy is feasible in the treatment of Asian children and young adults with sarcomas.

Abstract
Osteosarcoma (OGS) is the most common primary bone tumor in children and adolescents which requires a multidisciplinary approach to management. Although chemotherapy and surgery can cure more than half of localized OGS cases, the unique challenges faced by resource-limited countries like India make this outcome difficult to achieve. Various questions in the management of OGS including role of high-dose methotrexate (HDMTX) in neoadjuvant setting, triplet vs doublet chemotherapy, intensification of chemotherapy based on response in setting of doublet, and indigenous prosthesis in setting of limb salvage need to be defined. Similarly, in the metastatic and recurrent setting, questions regarding intent of treatment, indications of chemotherapy, timing of surgery, and role of targeted therapies need clarification. Lack of randomized trials from India makes definite conclusions difficult, but an attempt can be made to define the best approach in the Indian scenario from available evidence. Hence, a critical review of literature from India and the West was done to define possible management approaches and highlight the lacuna for future research.

Abstract
Although children and young adults with Hodgkin's lymphoma usually have a favorable prognosis, patients with primary refractory disease and some subsets of relapsed patients still have a dismal outcome. Brentuximab vedotin (BV) in combination with bendamustine may represent a suitable salvage therapy; data on 32 patients aged less than 25 years were retrospectively analyzed. Patients received up to six cycles of treatment of BV 1.8 mg/kg on day 1 and bendamustine 90-120 mg/m2 on days 2 and 3. At the end of treatment, the overall response rate was 81%. The 3-year overall and progression-free survivals are 78.1% and 67%, respectively.

Abstract
BVB was an effective and tolerable retrieval regimen for pediatric patients with R/R HL and resulted in minimal toxicity. Stem cell mobilization and collection was successful in patients before autologous stem cell transplant.
In patients with relapsed/refractory (R/R) Hodgkin lymphoma (HL), achieving a complete metabolic response (CMR) after salvage therapy is associated with superior outcomes, and optimal treatments must be identified. The combination of brentuximab vedotin and bendamustine (BVB), although highly active in adult patients, has not been extensively evaluated in pediatric patients with R/R HL. We performed a multicenter, retrospective review of pediatric patients <21 years of age with R/R HL treated with BVB from January 2016 through July 2019. Response was assessed by local radiologists according to Lugano classification criteria. Twenty-nine patients (17 relapsed, 12 refractory) with a median age of 16 years (range, 10-20) were treated with BVB and received a median of 3 cycles of therapy (range, 2-7). Patients received an infusion of 1.8 mg/kg of BV on day 1 with bendamustine 90 mg/m2 on days 1 and 2 of 3-week cycles. Nineteen patients (66%) achieved a CMR (95% CI, 46-82). An objective response was observed in 23 patients (objective response rate, 79%; 95% CI, 60-92). The most common grade 3 and 4 toxicities were hematologic, and 3 patients (10%) experienced grade 3 infusion reactions. Seventeen of 18 patients underwent successful mobilization and collection of stem cells. Sixteen patients (13 autologous, 3 allogeneic) received a consolidative transplant after BVB. The 3-year post-BVB event-free and overall survival were 65% (95% CI, 46-85) and 89% (95% CI, 74-100), respectively. For pediatric patients with R/R HL, BVB was well tolerated and compared favorably with currently accepted salvage regimens.

Abstract
Febrile neutropenia (FEN) is a significant side effect after chemotherapy, and it is known that using granulocyte colony-stimulating factor (G-CSF) has positive effects on treatment results. In this study, the effects of different G-CSF doses (5 to 10 mcg/kg/day) on treatment results in patients with high-risk FEN were evaluated. A total of 124 high-risk FEN episodes of 62 patients were enrolled in the study between June 2017 and October 2018. The episodes were divided into 2 groups according to G-CSF treatment doses, they received from 5 to 10 mcg/kg/day. The clinical characteristics of the patients, the treatments they received, laboratory findings, microbiologic results, and cost analysis were recorded. No statistically significant difference was found between 2 groups in terms of the mean duration of recovery from neutropenia, duration of fever, total length of hospital stay, duration of FEN episode, duration of G-CSF use, costs, bacteremia frequency, and other treatments. In patients with solid tumors, the cost of filgrastim was significantly higher in the high-dose G-CSF group. Using different doses of G-CSF in high-risk FEN episodes did not show any different effects on clinical and treatment results. The dose of 5 mcg/kg/day would be more appropriate in FEN treatment.

Abstract
Paediatric sarcomas are a heterogeneous group of disorders constituting bone sarcoma and various soft tissue sarcomas. Almost one-third of these presents with metastasis at baseline and another one-third recur after initial curative treatment. There is a huge unmet need in this cohort in terms of curative options and/or prolongation of survival. In this review, we have discussed the current treatment options, challenges and future strategies of managing relapsed/refractory paediatric sarcomas. Upfront risk-adapted treatment with multidisciplinary management remains the main strategy to prevent future recurrence or relapse of the disease. In the case of limited local and/or systemic relapse or late relapse, initial multimodality management can be administered. In treatment-refractory cases or where cure is not feasible, the treatment options are limited to novel therapeutics, immunotherapeutic approach, targeted therapies, and metronomic therapies. A better understanding of disease biology, mechanism of treatment refractoriness, identifications of driver mutation, the discovery of novel targeted therapies, cellular vaccine and adapted therapies should be explored in relapsed/refractory cases. Close national and international collaboration for translation research is needed to fulfil the unmet need.

Abstract
Immune dysregulation and predisposition to malignancies are critical comorbidities in children affected with ataxia telangiectasia. In addition, these children exhibit increased toxicity to conventional cancer therapy and dose reductions have been proposed to prevent life threatening adverse effects. These modifications to the treatment regimen may result in suboptimal outcomes for these patients. Our report of 3 children with ataxia telangiectasia and cancer highlight the immense challenges in the management of these children, underlining the need for the development of novel, biological agents with reduced acute and long-term side effects in the treatment of cancers in these children.

Abstract
We determined the risk factors associated with poor survival in children and adolescents with de novo mature B cell non-Hodgkin lymphoma (B-NHL) who had refractory or relapsed disease during or after the French-American-British mature lymphoma B (FAB/LMB) 96 multi-agent chemotherapy. Among the 1 111 registered on study, 104 patients (9·4%) had refractory disease or disease relapse after first complete remission. Among these 104 patients, 28 (27%) patients had refractory disease and 76 (73%) had relapsed disease. The estimated 1- and 2-year overall survival (OS) (95% confidence interval) was 31·5% (23·3-41·0%) and 22·3% (15·3-31·4%), respectively. Prognostic analysis of OS using a Cox multivariate model showed that factors independently associated with OS included lactate dehydrogenase ≥2 upper normal limit [hazard ratio (HR) = 2·86 (1·57-5·2), P = 0·0006]; time to failure (>6 months) [HR = 0·59 (0·36-0·97), P = 0·038]; and failure in bone marrow [HR = 2·78 (1·65-4·68), P = 0·0001]. New therapeutic strategies are required to significantly reduce refractory disease and disease relapse in patients with newly diagnosed mature B-NHL and, more importantly, there is a critical need to develop novel retrieval approaches in patients with chemotherapy-resistant disease.

Abstract
Cumulative myelosuppression is the main limiting factor for administration of repeated cycles of chemotherapy. We present a case series of five pediatric patients with high-risk solid malignancies who received small split peripheral blood stem cells (PBSC) doses of less than 1 × 106/kg CD34+ cells obtained after a single leukapheresis procedure and given after repeated cycles of ICE (ifosfamide, carboplatin, and etoposide) chemotherapy. Mean duration to absolute neutrophil count (ANC) recovery to >1000/mm3 and platelet recovery to >50 × 103/mm3 was 17.1 and 24.3 days. Using split doses of PBSC prevented prolonged neutropenia after repeated cycles of submyeloablative chemotherapy.

Abstract
The aim was to assess the activity of cisplatin (CDDP) in Ewing sarcoma (ES). The study consisted of front-line window therapy with CDDP 120 mg/sqm every 3 weeks for two courses in children and young adults with primary disseminated ES. Response was assessed using the Response Evaluation Criteria in Solid Tumours criteria, and Simon's two-stage design was applied. Twelve consecutive patients were enrolled in stage 1. Only one objective response was observed. Since the target response rate was not achieved, accrual was stopped and CDDP as a single agent in ES was judged unworthy of further assessment.

Abstract
BACKGROUND Ifosfamide, carboplatin, and etoposide (ICE) in children with refractory or recurrent solid tumors and lymphomas has resulted in good overall response rates (ORR). Etoposide, a topoisomerase-II inhibitor, however, has been associated with a significant increase in secondary leukemia. The rationale for substituting topotecan, a topoisomerase-I inhibitor, for etoposide in this regimen, a topoisomerase-II inhibitor, includes its limited toxicity profile and decreased leukemogenicity. Furthermore, topotecan in combination with both alkylators and platinating agents are additive and/or synergistic against a variety of solid tumors. PROCEDURE Patients with relapsed/refractory solid tumors received ifosfamide (9 g/m2 ) and carboplatin (area under the curve: 3 mg/ml/min). Topotecan was also administered at 0.5 mg/m2 /day × 3 days (N = 12) and in a small cohort (N = 3) at 0.75 mg/m2 /day. RESULTS Fifteen patients were entered onto study. Two patients developed seizures/encephalitis secondary to ifosfamide. One patient had dose-limiting thrombocytopenia secondary to TIC that resolved with supportive care. Patients received a median of three cycles (1-3) of TIC. Of the 14 evaluable patients for response, 4/14 had a complete response (CR), 2/14 had a partial response (PR), and 1/14 patients had stable disease (SD). The ORR (CR + PR) was 43%. CONCLUSION TIC chemotherapy is feasible and tolerable in children and adolescents with refractory/recurrent solid tumors and lymphomas and results in a 43% excellent ORR in this poor-risk group of patients. A larger cohort of patients, especially in Wilms tumor and central nervous system (CNS) tumors, should be studied in the future to attempt to confirm these preliminary findings.

Abstract
UNLABELLED This analysis was conducted to evaluate the efficacy and safety of carboplatin based chemotherapy in treating pediatric patients with Wilms tumors. METHODS Clinical studies evaluating the efficacy and safety of carboplatin based regimens on response and safety for pediatric patients with Wilms tumors were identified using a predefined search strategy. Pooled response rates (RRs) of treatment were calculated. RESULTS In carboplatin based regimens, 4 clinical studies which including 127 patients with advanced Wilms tumors were considered eligible for inclusion. With this carboplatin based chemotherapy, 2 clinical studies included carboplatin, ifosfamide and etoposide. Systemic analysis suggested that, in all patients, the pooled PR was 64.5% (82/127) in carboplatin based regimens. Thrombocytopenia and leukocytopenia were the main side effects. No grade III or IV renal or liver toxicity was observed. No treatment related death occurred with carboplatin based treatment. CONCLUSION This systemic analysis suggests that carboplatin based regimens are associated with a reasonable response rate and accepted toxicities for treating pediatric patients with Wilms tumors.

Abstract
Purpose The risk of febrile neutropenia (FN) in cancer patients receiving chemotherapy is mainly due to the type of chemotherapy regimen and the presence of specific risk factors in patients. The recent trend of using a dose-dense treatment schedule has enhanced the risk of FN. In the present prospective study, we evaluated the feasibility of a reduction of duration of therapy with colony-stimulating factor (G-CSF) in a dose-dense regimen. Methods Between June 2002 and December 2011, 107 patients with a new diagnosis of non-Hodgkin lymphoma (NHL) receiving dose-dense chemotherapy, every 14 days, were included in the study. The primary endpoint was defined as the completion of planned chemotherapy cycles as scheduled. Secondary endpoints were median number of administered G-CSF doses (vials), incidence of FN, hospitalization and toxicity. Results The planned chemotherapy cycles (primary endpoint) were completed by 84.1 % of patients. The median number of G-CSF (lenograstim) doses administered for each patient was 24 (range 10–35), which corresponds to a median of five vials (range 0–10) for each cycle. Grades 3–4 toxicities, related to G-CSF administration, included neutropenia and thrombocytopenia (14.0 and 1.9 %, respectively). No grades 3–4 bone pain was detected. The incidence of FN and hospitalization was 9.3 % (10/107) and 4.5 % (5/107), respectively. Conclusions Reduced dosage of G-CSF allows dose-dense chemotherapy scheduling, limits exposure to G-CSF and also represents an opportunity for cost savings.

Abstract
Risk-adapted, response-based therapies for pediatric Hodgkin lymphoma have resulted in 5-year survival exceeding 90%. Although high-dose chemotherapy and autologous hematopoietic stem cell transplantation (AHSCT) are considered standard for most patients with relapsed or refractory Hodgkin lymphoma, a subset of children with low risk relapse do not require AHSCT for cure. Currently there are no widely accepted criteria defining who should receive standard dose chemotherapy and/or radiotherapy, nor is there a standardized treatment regimen. We propose a risk-stratified, response-based algorithm for children with relapsed or refractory Hodgkin lymphoma that is based on a critical appraisal of published outcomes and prognostic factors.

Abstract
BACKGROUND Chemotherapy-induced neutropenia is a major cause of morbidity and mortality. It frequently causes dose reductions or treatment delay, which can be prevented or treated by the administration of granulocyte-colony-stimulating factor (G-CSF). However, a better knowledge of the incidence, day of onset after therapy, and duration of neutropenia is essential to optimize the use of G-CSF. DESIGN AND METHODS Six hundred and ninety-four patients from a single institution, affected by lympho-proliferative diseases, were retrospectively reviewed for the occurrence of grade 4 neutropenia and febrile neutropenia (FN). Duration of neutropenia and time of neutrophil nadir were also retrieved. The diagnoses included non-Hodgkin's lymphoma, Hodgkin's lymphoma, and multiple myeloma. Chemotherapy regimens were obviously different according to the diagnosis, disease stage, and first or subsequent lines of therapy. RESULTS No patient received G-CSF as primary prophylaxis. Median nadir did not significantly differ among patients treated with first or successive lines of therapy. The incidence of grade 4 neutropenia and FN ranged from 0 to 94%, depending on the chemotherapy regimen. Patients receiving a first-line chemotherapy regimen had a significantly lower incidence of febrile grade 4 neutropenia compared to patients treated with a second or subsequent line of therapy. The duration of grade 4 neutropenia was significantly longer in patients given second or subsequent lines. CONCLUSION The results of this study could be useful to define the nadir onset in the hematologic setting in order to correctly tailor timing and duration of G-CSF prophylaxis and to assess the lowest fully effective dose.

Abstract
BACKGROUND Acute B-cell leukemia (B-ALL) is a rare form of pediatric leukemia characterized by a very high-proliferation index, rapid clinical progression, and a high frequency of central nervous system (CNS) involvement. Commonly, it is treated in the clinical trials for Burkitt lymphoma, of which it represents the leukemic counterpart. PROCEDURE Children with B-ALL diagnosed between 1988 and 1999 were enrolled in the AIEOP-8805 protocol. Treatment included six high-dose chemotherapy courses. No prophylactic CNS irradiation was administered. RESULTS Sixty-five consecutive patients were enrolled in the study. L3 morphology was observed in 57 of 65 patients (88%). Twenty-five children (38%) had tumor mass in addition to massive bone marrow infiltration; 11 children (17%) had CNS disease at diagnosis. Sixty-two patients obtained complete morphological remission of which 13 suffered a relapse, including 3 with initial CNS involvement. Ten-year overall survival and event-free survival were 77% and 75%, respectively. Neither relevant long-term toxicity nor second malignancies were observed. CONCLUSIONS The AIEOP-8805 confirmed that short high-dose chemotherapy is highly effective for the treatment of B-ALL without significant long-term adverse sequelae. Therapy modifications to reduce relapse rate, such as the use of anti-CD20 monoclonal antibody and more effective CNS treatment, are being tested.

Short topotecan-based induction regimen in newly diagnosed high-risk neuroblastoma. Eur J Cancer 2010; 47:572-8. [PMID: 21112775 DOI: 10.1016/j.ejca.2010.10.023] [Citation(s) in RCA: 11] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2010] [Revised: 10/25/2010] [Accepted: 10/27/2010] [Indexed: 11/30/2022]
Abstract
PURPOSE Topotecan is an active drug in relapsed neuroblastoma. We investigated the efficacy and toxicity of a topotecan-based induction regimen in newly diagnosed neuroblastoma. METHODS Patients older than 1 year with either metastatic or localised stage 2-3 MYCN-amplified neuroblastoma received 2 courses of high-dose topotecan (HD-TPT) 6mg/m(2) and high-dose cyclophosphamide (HD-CPM) 140 mg/kg, followed by 2 courses of ifosfamide, carboplatin and etoposide (ICE) every 28 days. After surgery on primary tumour, a fifth course with vincristine, doxorubicin and CPM was given, followed by high-dose chemotherapy with stem cell support. Response was assessed in accordance with the International Neuroblastoma Response Criteria. RESULTS Of 35 consecutive patients, 33 had metastatic disease. The median length of induction phase was 133 days (range 91-207) and time to high-dose chemotherapy was 208 days (range 156-285). The median tumour volume reduction was 55% after two HD-TPT/HD-CPM courses and 80% after four courses. Radical surgery was performed in 16/27 patients after chemotherapy. After the fifth course, 29/34 patients (85%) had achieved a partial remission (12) or a CR/very good partial remission (17). CR of metastases was achieved in 13/32 (41%) and bone marrow was in complete remission in 16/24 patients (67%). Grade 4 neutropenia and/or thrombocytopenia occurred in 100% of HD-TPT/HD-CPM and in 95% of ICE courses, while non-haematological toxicities were manageable. CONCLUSIONS These data indicate that our induction regimen is feasible and well tolerated. A major response rate of 85% with 41% complete metastatic response confirms this regimen as effective induction in high-risk neuroblastoma.

Randomized trial of 2 dosages of prophylactic granulocyte-colony-stimulating factor after induction chemotherapy in pediatric acute myeloid leukemia. Cancer 2010; 117:1313-20. [PMID: 21381017 DOI: 10.1002/cncr.25536] [Citation(s) in RCA: 12] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2010] [Revised: 05/24/2010] [Accepted: 05/26/2010] [Indexed: 11/10/2022]
Abstract
BACKGROUND Granulocyte-colony-stimulating factor (G-CSF) is effective in accelerating neutrophil recovery after intensive chemotherapy for acute myeloid leukemia (AML). However, the optimal G-CSF dosage for patients with AML has not been determined. To the authors' knowledge, G-CSF dosages have not been compared in a randomized AML study. METHODS Patients who were enrolled on the St. Jude AML97 protocol and remained on study after window therapy were eligible to participate. The effect of the dosage of G-CSF given after induction chemotherapy Courses 1 and 2 was analyzed in 46 patients who were assigned randomly in a double-blinded manner to receive either 5 μg/kg daily or 10 μg/kg daily of G-CSF. The number of days of G-CSF treatment, neutropenia (an absolute neutrophil count <0.5 × 10(9) /L), and hospitalization; the number of episodes of febrile neutropenia, grade 2 through 4 infection, and antimicrobial therapy; transfusion requirements; the cost of supportive care; and survival were compared between the 2 study arms. RESULTS No statistically significant differences were observed between the 2 arms in any of the endpoints measured. CONCLUSIONS The higher G-CSF dosage (10 μg/kg daily) offered no greater benefit than the lower dosage (5 μg/kg daily) in patients who were receiving intensive chemotherapy for AML.

Abstract
BACKGROUND To estimate the response rate and therapy related toxicities of the anti-CD20 monoclonal antibody rituximab when combined with chemotherapy including ifosfamide, carboplatin, and etoposide (ICE) in patients with relapsed and refractory B-cell non-Hodgkin lymphoma and mature B-cell acute lymphoblastic leukemia (B-ALL). METHODS Patients received rituximab and ICE for 1-3 cycles, depending upon response. Rituximab (375 mg/m(2)) was given on day 1 and 3 of each cycle (day 1 only for cycle 3), with ifosfamide (3,000 mg/m(2)) and etoposide (100 mg/m(2)) given on days 3, 4, and 5 and carboplatin (635 mg/m(2)) given on day 3 only. RESULTS Twenty-one patients were enrolled, of whom 20 were eligible and evaluable. Although hematologic toxicities were common, only one patient was removed from study due to prolonged myelosuppression. Toxicities related to infusions of rituximab were frequent but manageable. Of the six eligible patients with diffuse large B-cell lymphoma, three achieved complete remission (CR), one had stable disease (SD), and two had progressive disease (PD). Of the 14 eligible patients with Burkitt lymphoma and B-ALL, there were four complete responses (CR), five partial responses (PR), one SD, and four with PD. Thus, the CR/PR rate for the entire group was 12/20 (60%). Following completion of protocol therapy six patients were able to proceed to consolidation with high-dose therapy and stem cell rescue. CONCLUSIONS The combination of rituximab and ICE chemotherapy was associated with an encouraging objective response (OR) rate and an acceptable toxicity profile.

Renal function after ifosfamide, carboplatin and etoposide (ICE) chemotherapy, nephrectomy and radiotherapy in children with Wilms tumour. Eur J Cancer 2008; 45:99-106.

Abstract
We prospectively evaluated tumour response and renal function in 12 newly diagnosed children with high-risk Wilms tumour receiving ifosfamide, carboplatin and etoposide (ICE) chemotherapy. Two cycles of ICE were followed by 5 weeks of vincristine, dactinomycin and doxorubicin (Adriamycin) (VDA), and nephrectomy, radiotherapy, additional VDA, and a third ICE cycle. Carboplatin dosage was based on glomerular filtration rate (GFR) to achieve targeted systemic exposure (6mg/ml min). Mean GFR (measured by technetium 99m-DTPA clearance) declined by 7% after 2 cycles of ICE and by 38% after nephrectomy; the mean carboplatin dose was reduced 32% after nephrectomy. Mean GFR remained stable after the third ICE cycle. Although urinary beta(2)-microglobulin excretion increased during therapy, no patient had clinically significant renal tubular dysfunction at the end of treatment. Treatment with ICE, nephrectomy and radiotherapy significantly reduces GFR, largely as the result of nephrectomy. Adjustment of carboplatin dosage on the basis of GFR and careful monitoring of renal function may alleviate nephrotoxicity.

Abstract
A 5-year-old male presented with spinal cord drop metastasis from a recurrent neurocytoma. Topotecan (0.5 mg/m(2)) and carboplatin (250 mg/m(2)) were administered on days 1-3 and ifosfamide (1,800 mg/m(2)) on days 1-5, every 21 days, for three cycles and resulted in complete response without severe complications. A literature review yielded 20 patients with central neurocytoma but no complete responses. The complete response of central neurocytoma to chemotherapy only reported here should be helpful to those caring for patients with this rare tumor.

High-dose cyclophosphamide inhibition of humoral immune response to murine monoclonal antibody 3F8 in neuroblastoma patients: broad implications for immunotherapy.

Abstract
BACKGROUND The murine monoclonal antibody 3F8 mediates lysis of neuroblastoma (NB) by complement and leukocytes (including neutrophils) but is neutralized if human anti-mouse antibody (HAMA) forms. We assessed the impact on rapid HAMA formation of prior chemotherapy in NB patients. METHODS For the 153 patients treated with 3F8 after conventional therapy (Group 1), the analysis included time from chemotherapy to the start of 3F8. For the 103 patients treated with 3F8 after myeloablative alkylator-based therapy (MAT) (Group 2), the analysis included both chemotherapy administered before stem-cell collection and time from MAT to the start of 3F8. RESULTS In Group 1, the incidence of HAMA-positivity was significantly lower if patients received high-dose cyclophosphamide (HD-Cy, > or = 4,000 mg/m2) before 3F8 treatment (P < 0.001). In addition, HAMA-positivity was least likely if 3F8 treatment was initiated <90 days post-HD-Cy (2/76 compared to 3/19 first treated at 90-120 days, and 17/27 first treated at >120 days, P < 0.001). In Group 2 patients who were transplanted with stem cells collected after HD-Cy, HAMA-positivity occurred in 1/60 patients treated <90 days post-MAT versus 13/23 treated >90 days post-MAT (P < 0.001). Among Group 2 patients transplanted with stem cells collected after no prior HD-Cy, the incidence of HAMA-positivity was significantly higher (15/19, P < 0.001), including 5/7 whose 3F8 treatment began <90 days post-MAT. CONCLUSIONS HD-Cy reliably blocks humoral responses to a murine antibody. This capacity to prevent host rejection of foreign or not fully humanized proteins raises the possibility of a broad role for HD-Cy in immunotherapeutic strategies.

Abstract
BACKGROUND The colony-stimulating factors (CSFs) are widely utilized to prevent neutropenic complications in both adults and children, but randomized controlled trials in the pediatric setting have reported varied results. A systematic review of the literature and meta-analysis were conducted to definitively assess the impact of prophylactic CSFs on the risk of febrile neutropenia (FN) in pediatric oncology patients. METHODS MEDLINE was searched and references hand-searched through July 2004 for randomized controlled trials of prophylactic G-CSF or GM-CSF in pediatric oncology patients. Objectives, outcomes, and quality of the 16 included studies were extracted by two reviewers. Weighted summary estimates of relative risks (RR) were calculated for FN and documented infection (DI). Mean differences in hospitalization, antibiotic use, and duration of neutropenia were calculated. RESULTS FN occurred in 68% of 400 controls and 59% of 404 CSF patients. The estimated RR was 0.88 [0.81-0.97; (P=0.01)] favoring the CSFs for leukemia and high grade lymphoma studies and 0.71 [0.51-0.97; (P=0.03)] for solid tumor studies. DI occurred in 25% of controls and 20% of CSF patients for an estimated RR of 0.80 [0.61-1.06; (P=0.12)]. The mean decrease in duration of neutropenia was 3.5 days [2.2-4.7; (P<0.0001)]. Mean decreases favoring CSF use were also observed for hospital stay of 1.7 days [0.9-2.5 (P<0.01)] and antibiotic use of 2.0 days [0.4-3.6; P=0.02]. CONCLUSIONS Prophylactic CSFs significantly decrease the incidence of FN and the durations of severe neutropenia, hospitalization, and antibiotic use in pediatric cancer patients, but they do not significantly decrease documented infections.

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
PURPOSE To evaluate the comparative efficacy of varying intensity schedules of recombinant human granulocyte colony-stimulating factor (G-CSF; filgrastim) support in preventing febrile neutropenia in early breast cancer patients treated with relatively high-dose epirubicin plus cyclophosphamide (EC). PATIENTS AND METHODS From October 1991 to April 1994, 506 stage I and II breast cancer patients were randomly assigned to receive, in a factorial 2 x 2 design, epirubicin 120 mg/m2 and cyclophosphamide 600 mg/m2 intravenously on day 1 every 21 days for 4 cycles +/- lonidamine +/- G-CSF. The following five consecutive G-CSF schedules were tested every 100 randomly assigned patients: (1) 480 microg/d subcutaneously days 8 to 14; (2) 480 microg/d days 8, 10, 12, and 14; (3) 300 microg/d days 8 to 14; (4) 300 microg/d days 8, 10, 12, and 14; and (5) 300 microg/d days 8 and 12. RESULTS All of the G-CSF schedules covered the neutrophil nadir time. Schedule 5 was equivalent to the daily schedules (schedules 1 and 3) and to the alternate day schedules (schedules 2 and 4) with respect to incidence of grade 3 and 4 neutropenia (P = .79 and P = .89, respectively), rate of fever episodes (P = .84 and P = .77, respectively), incidence of neutropenic fever (P = .74 and P = .56, respectively), need of antibiotics (P = .77 and P = .88, respectively), and percentage of delayed cycles (P = .43 and P = .42, respectively). G-CSF had no significant impact on the delivered dose-intensity compared with the non-G-CSF arms. CONCLUSION In the adjuvant setting, the frequency of prophylactic G-CSF administration during EC could be curtailed to only two administrations (days 8 and 12) without altering outcome. This nonrandomized trial design provides support for evaluating alternative, less intense G-CSF schedules for women with early breast cancer.

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
PURPOSE Ifosfamide, carboplatin, and etoposide (ICE) are associated with grade III/IV dose-limiting thrombocytopenia. The Children's Oncology Group conducted a phase I dose escalation, pharmacokinetic, and biological study of recombinant human thrombopoietin (rhTPO) after ICE in children with recurrent/refractory solid tumors (CCG-09717) to assess the toxicity and maximum tolerated dose of rhTPO administered at 1.2, 2.4, or 3.6 microg/kg per dose. EXPERIMENTAL DESIGN Children received ifosfamide 1,800 mg/m2 on days 0 to 4, carboplatin 400 mg/m2 on days 0 to 1, and etoposide 100 mg/m2 on days 0 to 4. rhTPO was administered i.v. on days +4, +6, +8, +10, and +12 at 1.2, 2.4, or 3.6 microg/kg per dose. RESULTS rhTPO was well tolerated and maximum tolerated dose was not reached. Median time to platelet recovery > or =100,000/microL of rhTPO at 1.2, 2.4, and 3.6 microg/kg/d was 24 days (22-24 d), 25 days (23-29 d), and 22 days (16-37 d), respectively. Patients required a median of 2 days of platelet transfusions (0-7 days). Mean (+/- SD) rhTPO maximum serum concentrations were 63.3 +/- 9.7 and 89.3 +/- 15.7 ng/mL and terminal half-lives were 47 +/- 13 and 64 +/- 42 hours after 2.4 and 3.6 microg/kg/d, respectively. There was a significant increase in colony-forming unit megakaryocyte upon WBC count recovery. CONCLUSIONS rhTPO was well tolerated. Time to hematologic recovery and median number of platelet transfusions seem to be improved compared with historical controls receiving ICE + granulocyte colony-stimulating factor (CCG-0894).

Abstract
BACKGROUND The prognosis for children with recurrent/refractory sarcomas is poor. We determined the overall response rate (ORR) and overall survival (OS) of children with recurrent/refractory sarcomas who were given ifosfamide, carboplatin, and etoposide (ICE) in three Children's Cancer Group (CCG) phase I/II trials. PROCEDURE Children with recurrent/refractory sarcoma were treated with ifosfamide (1,800 mg/m2/day on day 0-4), carboplatin (400 mg/m2/day on day 0-1), etoposide (100 mg/m2/day on day 0-4) and either rhG-CSF (10 microg/kg/day vs. 5 microg/kg/day, CCG-0894, 71 patients), PIXY321 (500-1,000 microg/m2/day, CCG-0924, 14 patients), or rhG-CSF (5 microg/kg/day) and IL-6 (2.5-5 microg/kg/day, CCG-0931, 12 patients). RESULTS Ninety-seven patients were evaluable for tumor response, 56 male and 41 female, median age 14.1 years (range 2.8-22.5 years). Tumor types were osteosarcoma (OTS) (n = 34), rhabdomyosarcoma (n = 27), Ewing sarcoma (EWS) (n = 21), soft tissue sarcoma-not otherwise specified (n = 5), undifferentiated sarcoma (n = 6), fibrosarcoma (n = 2), peripheral primitive neuroectodermal tumor (n = 1), and extraosseous Ewing (n = 1). The ORR was 51% (27% complete response [CR]). OS at 1 and 2 years was 49% and 28%, respectively. Patients with CR or partial response (PR) had significantly increased 1- and 2-year OS, 71% and 41%, respectively, (P < 0.001). Rhabdomyosarcoma patients with embryonal histology had significant improvement in 1- and 2-year OS: 82% and 46%, respectively, compared with other histologies, (P < 0.005). CONCLUSIONS The ORR to ICE reinduction chemotherapy in children with recurrent/refractory sarcoma was 51%. OS of 1 and 2 years appeared significantly improved in patients who had CR or PR following ICE reinduction therapy or who had rhabdomyosarcoma with embryonal histology.

Abstract
Thrombocytopenia remains the major dose-limiting toxicity of myelosuppressive chemotherapy in children with solid tumours. Recombinant human interleukin-11 (rhIL-11) has been approved by the Food and Drug Administration as treatment for adults with solid tumours and lymphomas with severe chemotherapy-induced thrombocytopenia. We conducted a phase I/II trial of rhIL-11 following ifosfamide, carboplatin and etoposide (ICE) chemotherapy in children with solid tumours or lymphomas. Patients received ifosfamide 1800 mg/m(2)/d for 5 d, carboplatin 400 mg/m(2)/d for 2 d and etoposide 100 mg/m(2)/d for 5 d with rhIL-11 subcutaneous (s.c.) at 25-125 microg/kg/d on days 6-33. Forty-seven patients with median age 10.5 years (range, 0.7-26 years) were studied. Median days to absolute neutrophil count >/=0.5 x 10(9)/l, platelet count >/=50 x 10(9)/l and platelet transfusions were 23, 18, 18, 16.5 and 18.5, 21, 20, 18 and 3, 3, 4, and 2 d at doses 25, 50, 75 and 100 Schulteg/kg respectively. There was a dose-dependent increase in C(max) (7.6-25.5 ng/ml), AUC(0-rho) (57-209 ng.h/ml) and T(1/2) (4-8.2 h) respectively. There was a 4% incidence of anti-IL-11 antibody formation. Clinically important adverse events to rhIL-11 were papilloedema and periosteal bone formation. In summary, rhIL-11 was well tolerated at doses of </=50 microg/kg (maximal tolerated dose) and associated with improved haematological recovery and reduced platelet transfusion requirements compared with historical controls receiving similar ICE chemotherapy without rhIL-11.

Abstract
BACKGROUND Failure of first line therapy for the Ewing's family of tumours (EFT) is associated with a very poor outlook. Studies of second line chemotherapy are therefore necessary to identify active agents and drug combinations. Cisplatin-based therapy is frequently used in these circumstances but there are few studies to clearly define activity and toxicity. This report details outcome in a cohort of patients with poor risk EFT treated with a carboplatin-based combination. PROCEDURE Between 1990 and 1998, 23 males and 16 females aged between 6 and 48 years (median 23) with relapsed or refractory EFT were treated with carboplatin-based chemotherapy. Previous chemotherapy had included ifosfamide and doxorubicin in all but two patients. Twenty patients were treated at the time of recurrence, and 19 after a poor response to initial chemotherapy. Treatment comprised of carboplatin to give an area under the plasma carboplatin concentration versus time curve of (AUC) 6 mg/ml, etoposide 120 mg/m2 for 3 days, and cyclophosphamide 500-750 mg/m2 for 2 days, repeated every 21 days. RESULTS A total of 105 cycles were given, median 2 per patient (range 1-5). Overall response was 26%, with one complete response and nine partial responses. Median time to progression was 10 weeks (range 2-54). Haematological toxicity was severe requiring dose reductions in 53% of patients. Six patients proceeded to high dose consolidation treatment with bone marrow or peripheral stem cell rescue. CONCLUSIONS This combination results in a substantial response rate in previously treated patients but with significant toxicity. Responses are, however, relatively short.

Abstract
Purpose To determine whether prophylactic hematopoietic colony-stimulating factors (CSFs) used in children with cancer reduce the rate of febrile neutropenia, hospitalization duration, documented infection rate, parenteral antibiotic duration, amphotericin B use, or infection-related mortality. Methods We included studies in this meta-analysis if their populations consisted of children, if there was randomization between CSFs and placebo or no therapy, if CSFs were administered prophylactically (before neutropenia or febrile neutropenia), and if chemotherapy treatments preceding CSFs and placebo or no therapy were identical. From 971 reviewed study articles, 16 were included. Results The mean rate of febrile neutropenia in the control arms was 57% (range, 39% to 100%). Using a random effects model, CSFs were associated with a reduction in febrile neutropenia, with a rate ratio of 0.80 (95% CI, 0.67 to 0.95; P = .01), and a decrease in hospitalization length, with a weighted mean difference of −1.9 days (95% CI, −2.7 to −1.1 days; P < .00001). CSF use was also associated with reduction in documented infections (rate ratio, 0.78; 95% CI, 0.62 to 0.97; P = .02) and reduction in amphotericin B use (rate ratio, 0.50; 95% CI, 0.28 to 0.87; P = .02). There was no difference in duration of parenteral antibiotic therapy (weighted mean difference, −4.3; 95% CI, −10.6 to 2.0 days; P = .2) or infection-related mortality (rate ratio, 1.02; 95% CI, 0.34 to 3.06; P = .97). Conclusion CSFs were associated with a 20% reduction in febrile neutropenia and shorter duration of hospitalization; however, CSFs did not reduce infection-related mortality.

Abstract
BACKGROUND Therapeutic trials using ifosfamide,carboplatin, and etoposide (ICE) regimen have suggested many patients with refractory/relapsed solid tumors may be rendered free of disease using this combination. The aim of this study was to assess the feasibility, response and toxicity of this regimen in a Brazilian Pediatric Oncology Centre. PROCEDURE ICE, consisting of ifosfamide 3 g/m(2)/day x3 plus Mesna, etoposide 160 mg/m(2)/day x3, and carboplatin 400 mg/m(2)/day x2 was given at 21-28 days intervals. G-CSF was used for patients with hematological recovery greater than 4 weeks. RESULTS Twenty-one patients younger than 18 years of age treated with this regimen were studied between July 1996 and November 2000. A total of 93 courses of ICE were administered. Leucopenia/neutropenia grades 3/4 were the most frequent severe adverse effects (82%). Grade 3/4 thrombocytopenia occurred in 73% of cycles, and anemia was common (61%). The most common grade 3/4 non-hematologic toxicities were fever and proved infection occurring in 25% and 14% of the courses, respectively. Two patients developed renal tubular damage. Other less common grade 3/4 non-hematologic toxicities included nausea and vomiting, hepatotoxicity, and stomatitis. The overall response rate (complete response/partial response) was 53%. The median progression-free interval was 15.3 months, with a median survival of 24.2 months. CONCLUSIONS Although ICE was associated with severe myelosuppression it produced objective response in about half of the cases. The most important non-hematological toxicity was severe renal tubular damage. This regimen should only be used whenever hematological and infectious supportive care is available.

Abstract
BACKGROUND The goal of the current study was to define the clinical features and outcome of recurrent osteosarcoma (OS) in children and young adults initially treated with contemporary chemotherapy. METHODS The authors reviewed the clinical features, therapy, and outcome for 59 patients from the Mayo Clinic (Rochester, MN) and Children's Hospital and Regional Medical Center (Seattle, WA). They were diagnosed initially with OS between January 1990 and December 2000, received multiagent chemotherapy (most frequently cisplatin, doxorubicin, high-dose methotrexate, and ifosfamide), and developed disease recurrence after achieving an initial complete response (CR). RESULTS The most common site of initial disease recurrence was the lung only (n = 36 patients), followed by distant bone (n =8 patients), combined lung and other sites (n =7 patients), and other sites (n =8 patients). The median time to first disease recurrence was 15 months (range, 2-92 months) from the initial diagnosis. Thirty patients with isolated pulmonary recurrence achieved a second CR, either with surgery alone (n =15 patients) or surgery and salvage chemotherapy (n =15 patients). For this group, the 4-year disease-free survival (DFS) and overall survival rates were 7% (95% confidence interval [95% CI], 0-16%) and 28% (95% CI, 11-45%), respectively. For all 59 patients with recurrent OS, the 4-year DFS and overall survival rates were 6% (95% CI, 0-12%) and 23% (95% CI, 10-36%), respectively. The only factors associated with improved DFS and overall survival rates were unilateral pulmonary recurrence, solitary pulmonary nodule at recurrence, more than 24 months between the initial diagnosis and first disease recurrence, and achievement of a second CR. CONCLUSIONS The DFS and overall survival rates for recurrent OS after contemporary therapy remained poor even for patients with isolated pulmonary recurrence. Therefore, new treatment strategies are needed.

Abstract
BACKGROUND Cisplatin (cDDP), when used either alone or, more often, in combination with other agents, especially adriamycin, achieves a high response rate in osteosarcoma. Its use, however, is limited by severe nephro- and neuro-toxicity. Second generation platinum compounds, most notably carboplatin (CBDCA), have been developed in order to attempt to reduce these dose-limiting toxicities, and thus improve the therapeutic ratio. Studies evaluating the role of combination CT containing CBDCA vs. cDDP have demonstrated differing results depending on the tumor type tested and its role in the treatment of osteosarcoma has yet to be clarified. PROCEDURE In this study, we compared the in vitro anti-tumor activity of cDDP and CBDCA in a panel of three human osteosarcoma cell lines (HOS, MG63, and U2OS). RESULTS cDDP and CBDCA (0-20 micromol) showed marked variation in cytotoxicity among the three cell lines. EC(50) values for CBDCA in HOS and MG63 cells were approximately two-fold higher than for cDDP and the ratio of AUC(CBDCA) to AUC(cDDP) varied from 1.8 in the HOS cell line to 2.3 in the MG63 cell line. Exposure of MG63 and HOS cells to either cDDP or CBDCA (1.67 and 13.5 micromol) caused a G2/M cell cycle arrest by 24 hr. Also evident was a sub G1 peak indicative of cell death by apoptosis. U2OS cells were relatively resistant to the cytotoxic effects of both drugs, although a cell cycle arrest in response to DNA damage was observed. This suggests that unlike MG63 and HOS cells, U2OS cells have either a more efficient repair pathway for platinum-induced DNA damage or are able to evade apoptosis. Examination of apoptotic events and cellular recovery demonstrated that both an 8-16-fold higher concentration and longer treatment period for CBDCA compared with cDDP was required to produce equivalent cell death and a loss of the ability of single cell clones to form colonies in both the HOS and MG63, but not the U2OS cell line. CONCLUSIONS Our findings suggest that CBDCA at a two- to four-fold higher concentration than cDDP has potential therapeutic activity in platinum sensitive osteosarcomas, particularly when cDDP cytotoxicity compromises therapeutic efficacy.

Abstract
Myeloid growth factors are widely used in both pediatric and adult oncology. Although the literature supporting the use of growth factors in pediatric oncology is less extensive than the adult literature, some uses are clearly established. Both granulocyte colony-stimulating factor and granulocyte-macrophage colony-stimulating factor shorten the duration of febrile neutropenia after myelosuppressive chemotherapy, effectively mobilize hematopoietic stem cells for transplantation, and enhance neutrophil engraftment after hematopoietic stem cell transplantation. Although some open-label, uncontrolled trials and retrospective analyses support growth factor use to ameliorate the number of infections, duration of hospitalizations, and duration of intravenous antibiotic use after myelosuppressive chemotherapy or to enhance dose intensity, randomized controlled trials supporting these practices are lacking.

Abstract
BACKGROUND The outcome of children with relapsed Wilms' tumor is poor, especially with poor-risk factors such as unfavorable histology, early recurrence, previous three-drug therapy, relapse not confined to lungs and abdominal relapse following abdominal radiotherapy. We report the overall response rate, progression-free survival and overall survival of 11 children with relapsed and poor-risk Wilms' tumor following ifosfamide/carboplatin/etoposide (ICE) chemotherapy. PATIENTS AND METHODS ICE therapy consisted of ifosfamide 1800 mg/m2/day (on day 0-4), carboplatin 400 mg/m2/day (on day 0-1) and etoposide 100 mg/m2/day (on day 0-4). The median age at diagnosis was 39 months (range from 13 months to 16 years) and the median time to relapse after initial diagnosis was 9 months (range 4-72 months). All but one patient had at least one poor prognostic feature, with eight patients showing three or four. RESULTS After ICE chemotherapy the number of patients showing a complete response (CR) was three (27%) and a partial response (PR) was six (55%). The overall response rate (CR+PR) was 82%. Five of the six patients with a PR subsequently achieved a CR with further therapy. The 3-year event-free survival and overall survival were 63.6 +/- 14.5%. CONCLUSIONS The response rate in children with relapsed and poor-risk Wilms' tumor is >80% with ICE re-induction chemotherapy followed by post-ICE therapy. The optimal approach for post-ICE consolidation therapy has yet to be determined.
