Abstract
The standard first-line therapy for glioblastoma consists of maximal surgical resection, followed by concurrent chemoradiotherapy. Optimal management for older glioblastoma patients is unknown as they have not been extensively studied in clinical trials. We report data from a series of 156 consecutive glioblastoma patients treated at our institution from 2007 to 2017. Compared to glioblastoma patients aged 70 or less, the patients older than 70 were less likely to undergo surgical resection (34% vs. 64%; p = 0.0003), be treated with adjuvant chemotherapy (37% vs. 59%; p = 0.01) or radiation therapy (36% vs. 56%; p = 0.03). Disease-specific survival was significantly shorter in this age group (4.7 vs. 15.3 months; p = 0.002). Nonetheless, when older patients did undergo surgery or chemotherapy, the proportional improvement in cancer-specific survival was similar to the one recorded in younger patients, which is concordant with the findings of other published reports. A multidisciplinary input from neurosurgeons, medical and radiation oncologists, oncology pharmacists and geriatricians remain paramount for the optimal management of glioblastoma in patients older than 70.
