Simon Lammy, MBBS, MRCS (Ed), MFST (Ed), University of Glasgow, Glasgow, UK, discusses the role of reoperation in treating patients with recurrent glioblastoma. As the previous clinical experience of healthcare professionals will influence the treatment pathway for patients, it is necessary for multidisciplinary discussions to be conducted to select patients for reresection. Older patients should not always be excluded from surgery due to perceived frailty and the location of the recurrence in the brain as well as existing comorbidities may influence clinical decisions. This interview took place at the British Neuro-Oncology Society (BNOS) Annual Meeting 2022.
