[Local therapy of primary brain tumors]. / Lokale Therapien bei hirneigenen Tumoren.

In recent years further forms of local treatment for primary brain tumors have been developed in addition to resection and radiation. There are basically three principles for local therapy, intralesional therapy for primary or recurrent non-resectable tumors as well as intracavitary and pericavitary therapy following microscopic surgical complete resection. Local therapy procedures are complex and suffer from special difficulties in the evaluation of their effectiveness by imaging techniques, because they are inevitably accompanied by alterations in the imaging, barrier disturbances and contrast medium uptake.
