Abstract
Background We report results from the phase I dose-finding and phase II expansion part of a multicenter, open-label study of single-agent lenvatinib in pediatric and young adult patients with relapsed/refractory solid tumors, including osteosarcoma and radioiodine-refractory differentiated thyroid cancer (RR-DTC) (NCT02432274). Patients and methods The primary endpoint of phase I was to determine the recommended phase II dose (RP2D) of lenvatinib in children with relapsed/refractory solid malignant tumors. Phase II primary endpoints were progression-free survival rate at 4 months (PFS-4) for patients with relapsed/refractory osteosarcoma; and objective response rate/best overall response for patients with RR-DTC at the RP2D. Results In phase I, 23 patients (median age, 12 years) were enrolled. With lenvatinib 14 mg/m2, three dose-limiting toxicities (hypertension, n = 2; increased alanine aminotransferase, n = 1) were reported, establishing 14 mg/m2 as the RP2D. In phase II, 31 patients with osteosarcoma (median age, 15 years) and 1 patient with RR-DTC (age 17 years) were enrolled. For the osteosarcoma cohort, PFS-4 (binomial estimate) was 29.0% [95% confidence interval (CI) 14.2% to 48.0%; full analysis set: n = 31], PFS-4 by Kaplan–Meier estimate was 37.8% (95% CI 20.0% to 55.4%; full analysis set) and median PFS was 3.0 months (95% CI 1.8-5.4 months). The objective response rate was 6.7% (95% CI 0.8% to 22.1%). The patient with RR-DTC had a best overall response of partial response. Some 60.8% of patients in phase I and 22.6% of patients in phase II (with osteosarcoma) had treatment-related treatment-emergent adverse events of grade ≥3. Conclusions The lenvatinib RP2D was 14 mg/m2. Single-agent lenvatinib showed activity in osteosarcoma; however, the null hypothesis could not be rejected. The safety profile was consistent with previous tyrosine kinase inhibitor studies. Lenvatinib is currently being investigated in osteosarcoma in combination with chemotherapy as part of a randomized, controlled trial (NCT04154189), in pediatric solid tumors in combination with everolimus (NCT03245151), and as a single agent in a basket study with enrollment ongoing (NCT04447755). The recommended phase II dose of lenvatinib in children with relapsed/refractory solid malignant tumors is 14 mg/m2. This dose is equivalent to the recommended dose of 24 mg/day for single-agent lenvatinib in adults with DTC. Single-agent lenvatinib showed activity of interest in children and young adults with osteosarcoma. Based on this initial report, lenvatinib is currently being investigated in combination with chemotherapy in osteosarcoma.

Abstract
BACKGROUND Congenital mesoblastic nephroma is a rare disease. Treatment is surgical in the first instance. Chemotherapy has traditionally been thought not to have a role. Recent literature suggests a 50% mortality rate for recurrent/metastatic disease. MATERIALS AND METHODS This study is a retrospective case review of prospectively collected data. Demographics, histopathology, treatment, outcomes and follow up were reviewed. RESULTS Nine patients, 6 male and 3 female, were included. The median age at presentation was one month (range 0-7 months); follow-up was for a median of 21.5 months (range 16-79 months). Two patients had mixed and classical subtypes and the other five had the cellular subtype. Surgery was completed by an open procedure in eight patients and laparoscopically in one. There were three recurrences; two were local and one was pulmonary. Recurrences were treated with a combination of chemotherapy, radiotherapy and surgery. One patient with recurrent disease died from acute-on-chronic respiratory failure secondary to lung irradiation but was disease free. The other eight are disease free, alive and well with no sequelae at latest follow-up. CONCLUSIONS Surgery remains the mainstay of management with chemo- and radiotherapy reserved for unresectable tumours or adjuvant management of recurrent disease. Specimen-positive margins are not an indication for instituting chemotherapy. The tyrosine kinase pathway seems to be a potential target for future chemotherapeutic agents although it is too early to assess how that will impact on the management of congenital mesoblastic nephroma.

Abstract
Cartilage-hair hypoplasia (CHH) is an autosomal recessive chondrodysplasia characterized by short-stature, sparse hair and impaired cellular immunity. We describe a young girl who was diagnosed with CHH based on the findings of recurrent infections, short stature with metaphyseal chondrodysplasia, and a confirmed bi-allelic RMRP gene mutation. At 13 years, the patient developed an Epstein-Barr virus (EBV)-driven lymphoproliferative disorder involving the lung, which responded partially to chemotherapy. Simultaneously, she developed multiple indurated plaques involving her face, which had histological findings of granulomatous inflammation and EBV-associated low-grade lymphomatoid granulomatosis. The patient received a matched unrelated peripheral blood stem cell transplant at 15 years of age, and her immunological parameters and skin lesions improved. Lymphomatoid forms of granulomatosis and cutaneous EBV-associated malignancies have not been described previously in CHH. This case highlights the possibility of EBV-associated cutaneous malignancy in CHH.

Abstract
BACKGROUND The prognosis for patients with nonpulmonary metastatic Ewing sarcoma remains poor with survival in the order of 15-20%. The need to introduce effective new agents into clinical practice is clear. Based on a preclinical rationale of responses in xenografts and backed by a phase I study in children, the Euro-E.W.I.N.G consortium planned a phase II window study of irinotecan in newly diagnosed high risk metastatic patients with Ewing sarcoma. PROCEDURES Patients were recruited between April 2004 and December 2007. Two courses of irinotecan were administered at a dose of 600 mg/m(2) as a 1 hour infusion at 21 day intervals. Response evaluation was determined after the second course of treatment by radiological assessment of primary and metastatic sites and, where appropriate bone marrow sampling. RESULTS Twenty-three patients were recruited. Two patients were deemed inevaluable for response. Five patients (24%) demonstrated a partial response. Grade 3 or 4 diarrhoea was seen in 4/43 course of treatment and was managed with loperamide. CONCLUSIONS This is the first report of single agent irinotecan activity in an untreated population of patients with Ewing sarcoma. In common with other paediatric tumours and other camptothecin analogues such as topotecan, single agent activity is only modest. The exact role for the use of irinotecan in patients with ES, dose schedule and combinations with other agents still requires further investigation.

Abstract
To compare the incidence of acute histologically proven rejection in children who have had a liver transplant for hepatoblastoma with a control group of children transplanted for biliary atresia (EHBA). A retrospective case notes based study was performed. Twenty patients were identified with hepatoblastoma who were transplanted at a single unit between 1991 and 2008. These were matched as closely as possible for age, gender, year of transplant and type of immunosuppression used to the control group transplanted for biliary atresia (n = 60). There was a significant decrease in rate of acute rejection as assessed by the rejection activity index (RAI) in the hepatoblastoma group (75% vs. 50%, respectively, p < 0.04). Chronic rejection was rare in both groups, but twice as common in the biliary atresia group. Equal levels of immunosuppression were achieved in both groups. Renal function was noted to be reduced one yr post-transplant in both groups, as previously reported. A modified immunosuppression regimen could be considered in children with hepatoblastoma undergoing liver transplantation.

Abstract
Overcoming childhood cancers is critically dependent on the state of research. Understanding how, with whom and what the research community is doing with childhood cancers is essential for ensuring the evidence-based policies at national and European level to support children, their families and researchers. As part of the European Union funded EUROCANCERCOMS project to study and integrate cancer communications across Europe, we have carried out new research into the state of research in childhood cancers. We are very grateful for all the support we have received from colleagues in the European paediatric oncology community, and in particular from Edel Fitzgerald and Samira Essiaf from the SIOP Europe office. This report and the evidence-based policies that arise from it come at a important junction for Europe and its Member States. They provide a timely reminder that research into childhood cancers is critical and needs sustainable long-term support.

Abstract
A teenage boy presented with a CD30-positive anaplastic large cell lymphoma (ALCL) affecting his scapula and was successfully treated with chemotherapy. His clinical features and outcome were compared with other cases described in the literature. A further review of 11 ALCL cases with bony involvement treated in the UK since 1990, including two with primary bone disease, did not suggest an unfavorable treatment outcome. This finding will need to be confirmed by further study on a larger patient cohort with primary bone ALCL.

Abstract
PURPOSE The aims were to identify and test the significance of specific factors associated with risks for anaesthesia in children with mediastinal tumours. PATIENTS AND METHOD Clinical information was retrospectively collected from the records of 63 children presented with mediastinal tumour (1964-2002) in a regional Paediatric Oncology centre and correlated with the type and outcome of anaesthesia, using non-parametric analyses. RESULTS Thirteen patients had local anaesthesia or sedation for diagnostic procedures and none developed any complication. Fifty children received general anaesthesia (GA) for diagnostic investigations or tumour resection. Two patients were excluded from the analysis because of treatment prior to GA. Problems with intubation, ventilation and cardiovascular collapse were encountered in 7 of 48 (15%) patients and this resulted in tracheostomy in one patient and death in 2 other cases. When compared with the 41 uncomplicated cases, the presence of at least 3 respiratory symptoms/signs, tracheal and vascular compression, and infection significantly increased the risk of GA. Of these, tracheal compression remained the strongest predictive factor. CONCLUSIONS Decision to postpone GA should be considered if all these risk factors (tracheal compression, vascular compression, the presence of at least three respiratory symptoms/signs) are present in the same patient.

Abstract
9003 Background: Imatinib mesylate inhibits selectively specific activations of the platelet-derived growth factor receptor (PDGFR), c-KIT and BCR/ABL tyrosine kinases and is approved for the treatment of chronic myeloid leukemia and gastro-intestinal stromal tumors (GIST). This study evaluated efficacy of imatinib in solid childhood tumors. Methods: Phase II study of imatinib as single agent in children and adolescents with refractory or relapsing solid tumor expressing at least one of the receptors. Patients were to be treated at 340 mg/m2, a dose escalation allowed to 440 mg/m2 after 2 months in case of insignificant improvement. C-KIT, PDGFRα and β expression was determined on archive tissue sections by immunohistochemistry prior to study entry. Gene mutations, pharmacokinetics, pharmacogenetics, and positron emission tomography imaging were assessed. Results: 36 patients, 21 boys, median age 13.7 years (2.2–22.5 y), 12 with brain tumors, 6 fibromatosis, 8 mesenchymal/bone tumors, and 10 other solid tumors, including 1 GIST and 3 chordoma, were treated at 340 mg/m2 daily during a total of 168 months (median 1.9 month/patient, range 0.5–19). 18/36 expressed c-KIT, 10 PDGFRα, 21 PDGRβ; 12 expressed more than one receptor. Ten patients were escalated to 440 mg/m2 due to lack of efficacy. During the 1st month, 17 patients experienced mild toxicity (grade 1 and 2) related to study treatment: gastro-intestinal (n=22), face edema (n=7), asthenia (n=5), tumor induration (n=2), skin toxicity (n=2), thrombocytopenia (n=1). No partial or complete response was observed; 5 patients (2 fibromatosis, 1 GIST, 1 medulloblastoma, 1 pseudo-inflammatory tumor) experiencing durable stable disease have been under treatment for more than 12 months. Interesting tumor stabilization during 10 and 7 months, respectively, was achieved in a brain stem glioma and a renal carcinoma. Glucose uptake on 18FDG PET scan was reduced in a chordoma, although the child progressed and died due to disease. Pharmacokinetic and genetic data are currently evaluated. Conclusions: Imatinib as single agent was well tolerated, but—as used in our study —failed to show measurable anti-tumor effects according the standard criteria in the pediatric malignancies studied. No significant financial relationships to disclose.

Abstract
9012 Background: To determine the response rate (RR) of neuroblastoma (NB) in children to temozolomide (TMZ), and evaluate the duration of response and tolerance of the drug in this patient population. Methods: A multicenter, phase II evaluation of an oral, daily schedule of TMZ (200 mg/m2 on 5 consecutive days and repeated every 28 days) was undertaken in children with a refractory or relapsed high-risk NB (metastatic or localized with Myc-N amplification). Evidence of activity was defined by radiologic or MIBG scan evidence of sustained reduction in lesion size or activity whenever it occurs. Methodology included a two-step study using Fleming’s method with a first step of 15 patients and a second of 10 additional patients if 2 to 4 responses had been observed in the first cohort. All data were centrally reviewed by a panel. Results: Among 34 registered patients over a 14 month period in 14 centres, twenty five are finally evaluable and received 94 cycles of chemotherapy. Disease status was metastatic NB (n=23) either refractory (n=9) or in relapse (n=14). Grade ¾ thrombocytopenia was the most frequent toxic event (16% of the cycles). Myelosuppression resulted in significant treatment delays and dose reductions (24% and 21% of cycles respectively). Out of 25 patients, response (CR, VGPR or PR) was observed in 5 (RR=20 ± 8%) with a median duration of 6 months. Furthermore a mixed response or an objective effect was observed in respectively 2 and 3 additional patients. Conclusions: Temozolomide is effective in heavily pretreated patients with NB, and deserves further evaluation in combination with another drug No significant financial relationships to disclose.

Abstract
Clear cell sarcoma of the kidney (CCSK) has been classified as high risk tumour in the previous UK and international Wilms tumor studies. The current Society of Paediatric Oncology (SIOP) trial, UK version, advocates chemotherapy including doxorubicin prior to nephrectomy. Pathological staging and histology of the resected tumor are then applied to determine the extent and intensity of the postoperative therapy. We describe an unusual case with a trilobed tumor and debate the appropriate postoperative management.

Abstract
Childhood cancer is a relatively rare disease, representing just 1% of all malignancies. Within Europe, this represents some 12,000 new cases each year, with approximately 1600 a year in the United Kingdom and 1800 in France. International collaboration in phase III trials of childhood cancer has been the norm for many years, traditionally within Europe, but, largely because of organisational considerations, phase I and II trials have only been conducted on a national basis. With overall cure rates in the region of 70%, relatively few children are available for these early drug trials. Access to new drugs is also a major problem. Against this background, a United Kingdom (UK)/French 'new agent' collaboration was established, expanding subsequently into a wider European grouping. This paper documents the history of that collaboration, the outcomes and future challenges.

Abstract
The authors discuss the morbidity associated with viridans streptococcus bacteremia, and its implications on the choice of antibiotics used as prophylaxis and treatment. They retrospectively studied the case notes of 38 children who were being treated for various malignant conditions in their unit and developed 40 episodes of bacteremia with viridans streptococci between October 1995 and January 1999. Viridans streptococci were the third commonest blood culture isolate during this period, after coagulase-negative staphylococci and Staphylococcus aureus. The majority of the isolates were Streptococcus mitis (55%). Others were S. sanguis (25%), S. oralis (12.5%), S. salivarius (5%), and S. acidominimus (2.5%). Twenty-five percent of the patients had been treated with regimens that included cytosine arabinoside, 60% were receiving prophylactic co-trimoxazole, and 87.5% were neutropenic. Thirty percent of patients had abnormal chest X-rays, and 15% were hypotensive; 2 patients required admission to the intensive care unit. Initial antibiotic therapy was changed because of failure of clinical response in 60% of cases, despite the infecting organism being sensitive in vitro. This study confirms the importance of viridans streptococci as a cause of bacteremia in pediatric hematology and oncology patients, leading to significant morbidity. Further work is required to establish the optimal treatment for viridans streptococcus bacteremia.

Abstract
A 4-year-old girl developed right metachronous Wilms tumor 2 years after completing treatment for a left-sided stage I Wilms tumor. The original treatment included 7 weeks of chemotherapy, delayed nephrectomy, and another 3 weeks of chemotherapy. The metachronous tumor on the right side extended into the inferior vena cava and right atrium. She developed pulmonary embolism as a result. She received chemotherapy and developed liquifaction of the tumor and toxic shock. She also had surgery. The patient is alive 3 years after the original diagnosis and 10 months after the relapse. The authors report this unusual case and discuss whether these cases can be identified early.

Abstract
BACKGROUND Liver transplantation now is proposed for managing selected hepatoblastoma cases. Indications are not yet well defined. METHODS The case records of 34 children with hepatoblastoma treated over a period of 10 years (1991 to 2000) were reviewed retrospectively. RESULTS All patients benefited from preoperative chemotherapy. Twenty patients underwent major hepatic resections. Twelve patients, in absence of residual metastasis, underwent liver transplant because the tumour remained unresectable after chemotherapy. Two patients who presented with recurrence after a right hepatectomy, benefited from transplant as a second option. Two other patients did not undergo surgery because of widespread disease or resistance to chemotherapy. Disease-free survival rates were 95% after surgical resection, 100% when primary transplant was performed in patients with good response to chemotherapy, 60% after transplantation in patients with poor response to chemotherapy, 50% in patients with transplant as second option, and 0% in patients not undergoing surgery. CONCLUSIONS Transplantation is a potentially curative option for unresectable hepatoblastoma when chemosensitive (decrease in alpha-fetoprotein and decrease in tumour size). In this context, also favourable cases with good response but difficult resections with doubtful margins of resection may best be proposed for primary transplantation. Patients with recurrent or resistant disease are not good candidates.

Abstract
BACKGROUND Despite the current widespread use of prophylactic G-CSF in children with solid tumours and leukaemia, its effectiveness has not been clearly demonstrated. This randomised study evaluates the role of G-CSF given after a 5-day intensification block in children with acute lymphoblastic leukaemia (ALL). PROCEDURE Forty-six children with ALL or T-Cell non-Hodgkins lymphoma (NHL) treated on MRC ALL 97, UKALL XI or UKCCSG 9504 NHL protocols were randomised to receive granulocyte colony-stimulating factor following either the first or the second block of intensive chemotherapy in a cross-over study to determine if the prophylactic administration of G-CSF could reduce the rate of readmission to hospital for management of febrile neutropenia. RESULTS There was a statistically significant difference in the rate of hospital admission in the group receiving prophylaxis, with 34 of 46 being admitted, compared to 42 of 46 patients in the control arm (74 vs. 91%; P=0.0386). There were no differences found in duration of hospital admission, haematological toxicity, neutrophil recovery or duration of supportive care between the two groups. There was no demonstrable cost benefit derived from the prophylactic administration of G-CSF. CONCLUSIONS This study shows that the prophylactic administration of G-CSF following intensification chemotherapy for childhood ALL and T-NHL produces a significant reduction in the rate of readmission to hospital for the management of febrile neutropenia.

Abstract
Pre-clinical studies indicate that cisplatin encapsulated in STEALTH((R))liposomes (SPI-77) retains anti-tumour activity, but has a much reduced toxicity, compared to native cisplatin. A phase I study was conducted to determine the toxicity and pharmacokinetics of SPI-77 administered to children with advanced cancer not amenable to other treatment. Paediatric patients were treated at doses ranging from 40 to 320 mg m(-2)by intravenous infusion every 4 weeks. Blood samples taken during, and up to 3 weeks after, administration and plasma and ultrafiltrate were prepared immediately. Urine was collected, when possible, for 3 days after administration. SPI-77 administration was well tolerated with the major toxicity being an infusion reaction which responded to modification of the initial infusion rate of SPI-77. Limited haematological toxicity and no nephrotoxicity were observed. No responses to treatment were seen during the course of this phase I study. Measurement of total plasma platinum showed that cisplatin was retained in the circulation with a half life of up to 134 h, with maximum plasma concentrations approximately 100-fold higher than those reported following comparable doses of cisplatin. Comparison of plasma and whole blood indicated that cisplatin was retained in the liposomes and there was no free platinum measurable in the ultrafiltrate. Urine recovery was less than 4% of the dose administered over 72 h. Results from this phase I study indicate that high doses of liposomal cisplatin can safely be given to patients, but further studies are required to address the issue of reformulation of liposomally bound cisplatin.

Abstract
A phase I study of nolatrexed, administered as a continuous 5 day intravenous infusion every 28 days, has been undertaken for children with advanced malignancy. 16 patients were treated at 3 dose levels; 420, 640 and 768 mg/m(2)24 h(-1). 8 patients were evaluable for toxicity. In the 6 patients treated at 768 mg/m(2)24 h(-1), dose-limiting oral mucositis and myelosuppression were observed. Plasma nolatrexed concentrations and systemic exposure, measured in 14 patients, were dose related, with mean AUC values of 36 mg(-1)ml(-1)min(-1), 50 mg ml(-1)min(-1)and 80 mg ml(-1)min(-1)at the 3 dose levels studied. Whereas no toxicity was encountered if the nolatrexed AUC was <45 mg ml(-1)min(-1), Grade 3 or 4 toxicity was observed with AUC values of >60 mg ml(-1)min(-1). Elevated plasma deoxyuridine levels, measured as a surrogate marker of thymidylate synthase inhibition, were seen at all of the dose levels studied. One patient with a spinal primitive neuroectodermal tumour had stable disease for 11 cycles of therapy, and in two patients with acute lymphoblastic leukaemia a short-lived 50% reduction in peripheral lymphoblast counts was observed. Nolatrexed can be safely administered to children with cancer, and there is evidence of therapeutic activity as well as antiproliferative toxicity. Phase II studies of nolatrexed in children at the maximum tolerated dose of 640 mg/m(2)24 h(-1)are warranted.

Abstract
PURPOSE Carboplatin dosing in adults with cancer is based on renal function. The purpose of the current study was to validate a previously developed pediatric carboplatin-dosing formula. PATIENTS AND METHODS Thirty-eight pediatric patients were randomized to receive a carboplatin dose calculated according to surface area or a renal function-based dosing formula. On the next course of therapy, the alternative dosing method was used for each patient. Carboplatin pharmacokinetics (based on free plasma platinum concentrations) were measured after both courses. RESULTS The mean observed areas under the carboplatin concentration-versus-time curve (AUCs) after renal function- and surface area-based dosing were 98% and 95% of the target AUCs, respectively. The variation in the observed AUC was significantly less after renal function-based dosing (F test, P =.02), such that 74% of courses had an observed AUC within +/- 20% of the target value, versus 49% for courses after dosing according to surface area. Only one of 22 courses at the center with the most experience with renal function-based dosing was associated with an AUC outside +/- 20% of the target value, versus nine of 22 courses after surface area-based dosing in the same center. There was a relationship (r(2) =.71) between carboplatin AUC and thrombocytopenia in 10 neuroblastoma patients treated with a combination of carboplatin, vincristine, etoposide, and cyclophosphamide. CONCLUSION Renal function-based carboplatin dosing in children results in more consistent drug exposure than surface area-based drug administration.

Abstract
BACKGROUND/PURPOSE Complete surgical resection after chemotherapy is the definitive treatment for hepatoblastoma. However, orthotopic liver transplantation (OLT) is now accepted as a treatment modality for patients with unresectable tumours. The aim of this study was to review a single center's experience of OLT for unresectable hepatoblastoma. METHODS A retrospective review of 8 patients with unresectable hepatoblastoma who were referred for liver transplantation was conducted. RESULTS The patients assessed had an age range of 5 to 105 months at presentation; median, 24 months, (5 boys; 3 girls). Two patients have familial adenomatous polyposis, and one has right hemihypertrophy. All 8 patients had received standard chemotherapy according to SIOP (International Society of Pediatric Oncology) protocols. Extrahepatic metastases were found in 3 patients at diagnosis, but none had detectable metastases at the time of OLT. Four patients continued chemotherapy while awaiting OLT. Three patients received whole grafts, and 5 received reduced grafts. The median follow-up period was 22 months (range, 2 to 78 months). Five patients are alive and well, although 1 patient had a second OLT for biliary cirrhosis secondary to biliary stricture at 6 years. Three patients died: one 26 days post OLT of sepsis and two of disease recurrence at 22 months and 70 months posttransplant. The actuarial survival rate is 88% and 65% at 1 and 5 years, respectively, whereas the overall survival rate is 62.5%. CONCLUSION OLT for unresectable hepatoblastoma without extra hepatic metastases is highly successful with a low recurrence rate.

Abstract
A phase I study of temozolomide administered orally once a day, on 5 consecutive days, between 500 and 1200 mg m(-2) per 28-day cycle was performed. Children were stratified according to prior craniospinal irradiation or nitrosourea therapy. Sixteen of 20 patients who had not received prior craniospinal irradiation or nitrosourea therapy were evaluable. Myelosuppression was dose limiting, with Common Toxicity Criteria (CTC) grade 4 thrombocytopenia occurring in one of six patients receiving 1000 mg m(-2) per cycle, and two of four patients treated at 1200 mg m(-2) per cycle. Therefore, the maximum-tolerated dose (MTD) was 1000 mg m(-2) per cycle. The MTD was not defined for children with prior craniospinal irradiation because of poor recruitment. Plasma pharmacokinetic analyses showed temozolomide to be rapidly absorbed and eliminated, with linear increases in peak plasma concentrations and systemic exposure with increasing dose. Responses (CR and PR) were seen in two out of five patients with high-grade astrocytomas, and one patient had stable disease. One of ten patients with diffuse intrinsic brain stem glioma achieved a long-term partial response, and a further two patients had stable disease. Therefore, the dose recommended for phase II studies in patients who have not received prior craniospinal irradiation or nitrosoureas is 1000 mg m(-2) per cycle. Further evaluation in diffuse intrinsic brain stem gliomas and other high-grade astrocytomas is warranted.

Abstract
PURPOSE Infection in neutropenic patients is potentially life-threatening and carries important implications for hospital resource use. Prophylactic administration of cytokines may reduce the severity of neutropenia, but involves the treatment of all patients for the possible benefit of a minority. This study evaluates whether treatment with cytokines in the setting of established febrile neutropenia will influence outcome and be potentially more cost-effective. PATIENTS AND METHODS In a double-blind study, pediatric patients with fever and severe neutropenia were randomized to receive granulocyte colony-stimulating factor ([G-CSF] filgrastim; 5 microg/kg/d) or placebo, in addition to antibiotics. The study protocol required a resolution of fever and a neutrophil count > or = 0.2 x 10(9)/L for hospital discharge. Patients could be randomized for up to four independent febrile episodes. A total of 186 episodes of febrile neutropenia were investigated. RESULTS Patients randomized to G-CSF had a shorter hospital stay (median, 5 v 7 days; P = .04) and fewer days of antibiotic use (median, 5 v 6 days; P = .02). G-CSF-treated patients also had more rapid neutrophil recovery and higher neutrophil levels at discharge. The 2-day reduction in hospital stay reduced the median bed cost by 29% per patient admission (P = .04). CONCLUSION Under the clinical guidelines of our institution, the use of G-CSF in the treatment of established febrile neutropenia produced a small but significant reduction in the time that children required antibiotics and hospital admission, with possible cost savings.

Abstract
Synovial sarcoma of the larynx is extremely rare having been reported only six times previously in the literature. We add another case report, which to our knowledge is the first recorded case in a child. We discuss the alternative approach of combination chemotherapy and radiotherapy which in this case led to a remission lasting about 3 years. The immunohistological and ultrastructural characteristics of the tumour are also presented.

Abstract
We have investigated the effectiveness of three different F(ab' gamma)2 bispecific antibodies (BsAb) for delivering the ribosome inactivating protein (RIP) saporin via the CD7 or CD38 cell surface molecules to the human T-ALL cell lines HSB-2 and HPB-ALL. Inhibition of 3H-leucine uptake by target cells was used as the parameter of cellular cytotoxicity. Used singly against HSB-2 cells in the presence of varied concentrations of saporin, an anti-CD7 BsAb, (HB2 x DB7-18) and an anti-CD38 BsAb (OKT10 x RabSap), gave 435- and 286-fold increases in saporin toxicity, respectively. For HPB-ALL cells the anti-CD7 BsAb performed poorly giving only an eight-fold increase in toxicity whilst on the same cell line the anti-CD38 BsAb was highly potent giving an 80,000-fold increase in saporin toxicity. A combination of both BsAb used together against HSB-2 cells was ten times more effective, than the best single BsAb HB2 x DB7-18 used alone. Kinetic studies conducted with HSB-2 cells revealed that the BsAb combination also gave an increased rate of protein synthesis inactivation in comparison to either BsAb used alone. These investigations clearly demonstrate a synergistic action when both BsAb are used in combination to target saporin against CD7 and CD38 expressed on the surface of the HSB-2 cell line.

Abstract
We have investigated the efficacy of a F(ab'gamma)2 bispecific antibody (BsAb) with dual specificity for the CD7 molecule in one Fab arm and for the ribosome inactivating protein (rip) saporin in the other arm, for delivering saporin to the acute T-cell leukaemia cell line HSB-2. Saporin titration experiments revealed that BsAb increased the toxicity of saporin 435-fold for HSB-2 cells, reducing the IC50 for saporin alone from 0.1 mumol to 0.23 nmol when BsAb was included. The rate of protein synthesis inactivation brought about by BsAb-mediated toxin delivery to HSB-2 cells was very similar to that described for conventional immunotoxins (IT's) with a t10 (time taken for a one log inhibition of protein synthesis compared with controls) of 46 h obtained at a saporin concentration of 1 nmol and 226 h at 0.1 nmol. BsAb titration studies demonstrated a clear dose response effect of BsAb concentration on target cell protein synthesis inhibition and cell proliferation. The absolute specificity of toxin delivery was unequivocally demonstrated by a failure of BsAb to deliver an effective dose of saporin to the CD7- cell line HL60 and by the blocking of BsAb-mediated delivery of saporin to HSB-2 cells with an excess of F(ab)2 fragments of the anti-CD7 antibody, HB2. These studies have clearly demonstrated the effectiveness of this BsAb for delivering saporin to a T-ALL cell line utilising CD7 as the target molecule on the cell surface. BsAb's would therefore appear to offer a realistic alternative to IT's for toxin delivery to tumour cells and may even offer certain advantages over conventional IT's for clinical use.
