Repeated reports of more than ten years postoperative survival in patients with glioblastoma multiforme (GM) have appeared in the literature over the last decades. Authors have tried to identify the clinical, therapeutic and histological features determining long-term survival. We present two patients in whom, after radical removal of the tumor followed by conventional radiation, there has been no recurrence for at least ten years. The young age of the patients and the radical surgical approach were in accordance with previous reports of long-term survival. Nevertheless, one tumor originated from the thalamus, a location considered to be of unfavorable prognosis. We therefore further discuss the value of clinical signs as determinants in the prognosis of GM.
