title: [Principles of drug therapy of malignant tumors: the role of malignant progression in the choice of effective drugs].
abstract: The progress that has been achieved in the development of antitumour drugs and the management of the untoward side effects both contributed to the increasing importance of drug-therapy beside surgery and radiotherapy in cancer treatment. The treatment of the micrometastasis which appears very frequently already at the time of the diagnosis and also the control of the metastatic progression represent the main importance of drug therapy in cancer patients. In spite of the numerous clinical trials indicating the usefulness of drug therapy both as adjuvant in the management of the primary tumours and in the treatment of metastatic tumours there are certain reservation against chemotherapy in medical circle. It is noteworthy that at the present time the strategy of cancer-therapy is subject of considerate changes. Beside to achieve cure by eradication of the tumour cells it has been recommended in various oncological center that stabilization of the malignant disease and to offer a good quality of life for the patients should also be the aim of the therapy. The purpose of this communication is to present those factors which are necessary to consider in the planning of anticancer drug therapy. Certainly to achieve cure or to improve the quality of life of cancer patients it is important to select the most appropriate drug (cytostatics, hormones, biological response modifiers or agents improving the quality of life) and treatment schedule. Since antitumour drug therapy must be classified as active, palliative/active, palliative and supportive/terminal treatments the present survey gives emphases on the underlying role of malignant progression before deciding the type of treatment.
