- •We report a retrospective analysis of 151 elderly glioblastoma (GBM) patients.
- •Higher KPS, macroscopical total resection, radiotherapy and chemotherapy positively influence overall survival (OS).
- •Advanced age, seizure at onset, antiepileptic treatment and additional surgical resection did not influence OS.
- •In elderly fit patients extensive surgery and adjuvant treatment should be proposed.
- •Randomized controlled study is needed to develop treatment guidelines for elderly GBM patients.
The appropriate treatment approach for elderly patients with glioblastoma multiforme (GBM) is unclear, although different studies suggest survival benefit in fit patients treated with radiotherapy and chemiotherapy after surgery. We performed a retrospective analysis of 151 patients older than 65 years with GBM treated in 3 Lombardia Hospitals. In univariate regression analysis higher KPS (p = 0.02), macroscopical total resection (p < 0.003), radiotherapy (p < 0.0001), chemotherapy (p < 0.0001) and second line chemotheraphy (p = 0.02) were of positive prognostic value. On the contrary older age (>70 years), presence of seizure at onset and additional resection after tumor recurrence did not influence OS. Multivariate analysis revealed radiotherapy (HR 0.2 p < 0.0001) and extent of surgery (HR 0.3, p = 0,0063) as positive independent prognostic factors. Patients receiving radio-chemiotherapy displayed more treatment-related toxicities with a slightly prolonged OS versus those receiving hypofractionated radiotherapy. With the limits of a retrospective study, our data suggest that in elderly fit patients extensive surgery should be considered, moreover adjuvant treatments led to an increase in OS. Randomized controlled study are needed to develop treatment guidelines for elderly GBM patients and to assess whether the combination of post-surgical radio and chemiotherapy may be superior to hypofractionated radiotherapy and chemiotherapy in fit patients.
