Treatment of tumours

Technical progress made in neuroradiology, and focal external and internal radiation therapy, have allowed the development of a series of local therapeutic modalities both in primary and in metastatic brain tumours. Eligibility criteria and results obtained with these new techniques are compared. Experimental studies with implications for radiation therapy, particularly boron neutron capture therapy, and for chemotherapy are reviewed. The possible use of chemotherapy as first-line treatment in non-Hodgkins lymphomas of central nervous system is stressed.
