Six year survival after prolonged temozolomide treatment in a 30-year-old patient with glioblastoma.

ABSTRACT

Glioblastoma (GBM) is the most malignant primary brain tumour in adults. Since 2005 surgery followed by radiotherapy with concomitant Temozolomide (TMZ) is the standard care for patients with a GBM. Despite these improved treatment strategies, survival of GBM-patients remains poor; and there are very few patients who survive for a long time. Also there is no standard therapeutic strategy after six cycles of TMZ, and further treatment is at the physician's discretion. We report a case of a young patient with a glioblastoma who, not only showed dramatic clinical and radiological improvement after TMZ treatment but who now also (under continued TMZ therapy) survives over 6 years, with complete remission clinically and radiologically. Up till now there are no studies describing TMZ treatment in GBM patients for as long as 6 years.
