Biological bases and clinical implications of tumor radioresistance

International experts discuss the relevance of biology and radiation therapy, offer critical evaluations of therapeutic procedures and make recommendations for future development of methods of cancer treatment. Topics include the limitations of normal tissue tolerance, attempts to improve the therapeutic ratio by manipulation of the time factor, and a review of the present state-of-the-art giving the results of conventional irradiation and describing some of the ways of maximizing the effectiveness of existing means of treatment.
