General Introduction Malignant disease needs a multidisciplinary approach In addition to surgery,radiotherapy and chemotherapy, attention to psychiatric and social factors is also essential. In some cases,chemotherapy is given following surgery in the knowledge that widespread microscopic dissemination almost certainly has occurred (this is termed 'adjuvant chemotherapy'). If the tumour is widespread at presentation,systemic chemotherapy is more likely to be effective than radiotherapy or surgery,although these may be used to control local disease or reduce the tumour burden before potentially curative chemotherapy
