A multicenter, two stage phase II study, investigated irinotecan plus temozolomide in children with newly diagnosed high grade glioma. The primary endpoint was tumor response during a two-cycle treatment window, confirmed by external review committee. Patients received oral temozolomide 100 mg/(m 2 day) (days 1-5) and intravenous irinotecan 10 mg/(m2 day) (days 1-5 and 8-12) for two 21-day cycles (three cycles for patients exhibiting objective tumor response). Standard treatment was then administered according to local investigator choice. In total 17 patients were enrolled and treated by local investigators. However, central pathology review found three patients did not have a diagnosis of high grade glioma and another four patients did not have evaluable disease according to independent central radiological review. The primary endpoint was based on the first ten evaluable patients as determined by the external review committee. Recruitment was stopped for futility after there were no complete or partial responses during the two-cycle treatment window in the first ten evaluable patients. Five patients had stable disease, and five progressed. Data for secondary endpoints including; time to tumor progression, time to treatment failure, and overall survival is reported. The safety profile of the treatment showed the combination was tolerable with two patients (11.8 %) having grade three nausea, and one (5.9 %) experiencing a grade four neutropenia, leading to permanent discontinuation from adjuvant treatment. Irinotecan plus temozolomide, although well tolerated did not improve outcome over historical controls in this setting. © 2013 Springer Science+Business Media New York.

This study estimated the incidence of viral hepatitis in children treated for cancer, to identify variables that could affect this incidence and to assess the role of hepatitis B virus (HBV) vaccination in preventing infection. Between September 2007 and June 2008, 256 children in the haemato-oncology unit at the Childrens Welfare Teaching Hospital, Baghdad, were studied prospectively. Demographic and clinical data and vaccination history were recorded. Patients were tested for HBV at the time of diagnosis (all were negative) and after starting chemotherapy. On admission to the unit, 231 patients (90.2%) were revaccinated. At reassessment after treatment for cancer, HBV infection was found in 70 patients (27.3%). The variables that significantly increased the risk for HBV infection were a diagnosis of leukaemia and receiving more than 3 units of blood. A higher number of HBV vaccinations in hospital reduced the risk for HBV infection. The high rate of acquisition of HBV infection found in this study indicates the need for better screening of blood products and adherence to aseptic techniques in management of this group of patients.
