The aims of this study were to determine the maximum tolerated dose (MTD), toxicity and pharmacokinetics of oral temozolomide administered over 42 d in children with recurrent/refractory brain tumours. Cohorts of 3-6 patients were treated for 42 d, followed by a 7-d rest period for a maximum of 6 cycles. Patients were stratified as heavily pre-treated (HPT) and non-heavily pre-treated (NHPT). ⋯ In conclusion, the recommended dose of temozolomide is 85 mg/m2 x 42 d. Dose-limiting toxicities are thrombocytopenia and lymphopenia. The observed response rate warrants phase II studies.

The aim of this study was to assess regional survival differences among childhood cancer patients in Europe. For this exercise, the Automated Childhood Cancer Information System (ACCIS) database was utilised. Survival data from 54 population-based cancer registries on 49,651 childhood cancer patients aged 0-14 years and diagnosed in 1988-1997 were analysed using life-table method. ⋯ The geographical differences indicate the need for more co-ordination, systematisation and standardisation in diagnosis, referral and the treatment of childhood cancers in Europe. Increase of resources is necessary to improve the lower survival in the East region. Continuing data collection on a European level will facilitate monitoring of population-based survival of childhood cancer patients.
