Pan-European collaboration in studies of novel therapies and treatment strategies in childhood cancer is playing an increasing role in the attempt to improve cure rates. Differences in the systems of various countries with regard to drug control and ethical issues may lead to problems and delays. This applies in particular to phase I/II studies in children where the ethical considerations may be complex. In this review, the systems in three large countries-UK, France and Germany-are reviewed and current moves within the European Community towards a more standard approach are discussed.

To elucidate which symptoms or problems to measure when evaluating palliative care, we assessed the content validity of selected patient self-assessment questionnaires used to evaluate palliative care: the European Organization for Research and Treatment of Cancer-Quality of Life-Core 30 (EORTC QLQ-C30), the Edmonton Symptom Assessment System (ESAS), the Palliative Care Outcome Scale (POS), the McGill Quality of Life Questionnaire (MQOL) and the Memorial Symptom Assessment Scale (MSAS). The content of the questionnaires was compared against the symptoms and problems noted in the medical records of 171 consecutive cancer patients on their first admission to a department of palliative medicine. ⋯ Two questionnaires covered almost all of the prevalent symptoms/problems: the EORTC QLQ-C30 covered 10 and the MSAS 11 of the 12 most frequent problems. Researchers selecting instruments for evaluating palliative care may use the present study and other reviews to examine to what degree a given selection of instruments cover the symptoms/problems targeted by palliative care physicians.

The methodology for conducting cancer clinical trials has undergone enormous changes over the past 25-30 years since the EORTC Data Center was created. The purpose of this paper is to highlight and to provide a historical perspective for the main methodological concepts, both practical and theoretical, which form the basis for the design and analysis of phase III cancer clinical trials within the EORTC Data Center. Some statistical aspects of other associated topics such as quality of life, health economics, meta-analysis and treatment outcome will also be briefly discussed. Finally, some future perspectives and topics for further statistical methodological research will be presented in order to spur statisticians to meet the challenge of efficiently designing and analysing the clinical trials of tomorrow.

Early drug development at EORTC has always been subject to structural changes to adapt to the rapid changes that occur in oncological drug development. The expertise of early drug developers has always been cross-fertilised with disease-/tumour-oriented groups and also backwards to the laboratory research groups. This results in the establishment of a solid and dedicated network of medical oncologists with focused expertise in cancer drug development. ⋯ The EORTC New Drug development Programme (NDDP) provides methodological expertise to early clinical trials and coordinates phase I and phase II studies addressing various approaches. Through NDDP, the early clinical groups and the disease-/tumour-oriented groups have created specific networks to address early drug development in specific tumour types. This results in very efficient networks which have the resources and the patients to address and conduct challenging clinical trials in a standardised fashion ensuring the highest standards in cancer treatment.
