Gliadel for brain mets – pro

Gliadel®, followed by standard radiotherapy, is an option for selected patients with newly diagnosed malignant glioma where a near-gross total excision is possible; however, the majority of patients with malignant glioma will not be eligible for various reasons (i.e. non-resectable tumours or contact with the ventricular system). Gliadel® is also an option in patients with surgically resectable recurrent malignant gliomas.

Several studies have looked at the rlol of Gliadel in treating brain metastases. Ninety-three patients with brain metastases (new and recurrent) were studied by three groups In these three studies, 66 patients received WBRT following resection and wafer placement and 27 patients in the PROLONG study received no WBRT. During the follow up, there was no local recurrence reported in 91 patients and only two neurologically related deaths. Therefore, data in these studies show that there may be a benefit for local chemotherapy with Gliadel.
