The subject of the Sixth Symposium on Clinical Oncology of the Royal College of Radiologists held in February 1984 was ovarian cancer. This publication presents the collected papers delivered at that meeting, but excludes much useful discussion which also took place. The annual clinical oncology symposia have been designed to re- view topics of current interest in cancer therapy from a multidis- ciplinary point if view. It was gratifying to the organisers and all who took part that the aims were so well met by both the contrib- utors and discussants. We believe that this can only be to the...

The seventh annual multidisciplinary symposium on clinical oncology organised by the Royal College of Radiologists discussed the subject of malignant brain tumours. It was held in London in February 1985 and this volume collects together the edited texts of the papers which were presented at the meeting. Primary tumours of the central nervous system account for about 9070 of all malignant diseases but as much as 20% of all paediatric neoplasms. The prognosis ranges from excellent for some of the less aggressive tumours, through good for children's tumours such as medulloblastoma, to appalling...

The ninth annual multidisciplinary symposium on clinical oncology organized by the Royal College of Radiologists was jointly arranged with the International Society for Radiation Oncology. It was held in London in February 1987 and discussed the biological and clinical basis of the effects of radiotherapy. Wherever possible lectures by an experimental scientist were paired with those of a clinical scientist in order to emphasize clinical relevance. It is hoped that this has resulted in a widely balanced view of the subject. The volume presents an updated version of these subjects based on...

The eighth annual multidisciplinary symposium on clinical oncol- ogy organised by the Royal College of Radiologists discussed the subject of investigational techniques in oncology. It was held in London in February 1986. This volume collects together the edited texts of the papers which were presented at the meeting, together with the George Edelstyn memorial lecture given by Professor J. Einhorn. Clinicians rely very heavily on pathologists and radiologists to help with the diagnosis and staging of patients who present with malignant tumours. The conventional techniques to which we have...
