In case of circumscribed recurrent glioblastoma (rec-GBM), a second surgery (Re-S) and reirradiation (Re-RT) are local strategies to consider. The aim is to provide an algorithm to use in the daily clinical practice. The first step is to consider the life expectancy in order to establish whether the patient should be a candidate for active treatment. In case of a relatively good life expectancy (>3 months) and a confirmed circumscribed disease(i.e. without multiple lesions that are in different lobes/hemispheres), the next step is the assessment of the prognostic factors for local treatments. Based on the existing prognostic score systems, patients who should be excluded from local treatments may be identified; based on the validated prognostic factors, one or the other local treatment may be preferred. The last point is the estimation of expected toxicity, considering patient-related, tumor-related and treatment-related factors impacting on side effects. Lastly, patients with very good prognostic factors may be considered for receiving a combined treatment., (Copyright © 2020 Elsevier B.V. All rights reserved.)

GBM (glioblastoma multiforme) is the most common and aggressive brain tumor. To date, treatment options for glioblastoma recurrence are lacking. Recently, REGOMA trial showed the superiority of regorafenib to lomustine in patients with first glioblastoma recurrence. We report an excellent response to three months treatment with regorafenib, in a patient who presented a rapid progression after the end of post operative radio-chemotherapy and after only one cycle of adjuvant TMZ (Temozolomide)., (Copyright © 2020.

Purpose: Older patients with brain metastases (BM) are often excluded from clinical trials. The aim of our study was to investigate the outcomes following Gamma Knife radiosurgery (GKRS) in young old (65-74 years) and very old (≥75 years) patients with BM., Methods: Between October 2012 and October 2018, we treated 89 patients aged ≥65 years with GKRS. Patients were divided in two group: young old (YO) and very old (VO) patients. At baseline G8, Graded Prognostic Assessment (DS-GPA) and Basic Score for Brain Metastases (BSBM) were assessed for all patients. Survival analysis was estimated using the Kaplan-Meier (KM) method. Cox regression model was used to investigate the influence of significant factors on KM., Results: Median age at the time of GKRS was 72.2 years (range 65-87). A mean of 2.52 lesions were treated per patient (range 1-14). Median overall survival (OS) for YO and VO patients was 14.2 and 15.7 months, respectively. At univariate analysis, there were no significant differences in OS between the two age groups. A high BSBM (p ≤ .0001) and a high DS-GPA score (p = .0069) were associated with longer survival. A low DS-GPA score was the most powerful independent factor for predicting short survival (HR 1.76, 95% CI 1.25-2.46, p = .001) at multivariate analysis., Conclusion: GKRS is a safe approach to treat BM in elderly patients. DS-GPA score represents an important prognostic factor for survival in elderly patients undergoing GKRS., (Copyright © 2020. Published by Elsevier Ltd.)
