RESUMEN
BACKGROUND: Diffuse gliomas are the most frequent neoplasms in adolescent and young adults (AYAs), especially high-grade gliomas, which have the highest mortality rate. Recent histo-molecular advances are in favour of specialized therapeutic management of AYA patients, which we have analysed in this comprehensive review of the literature. SUMMARY: A literature search was conducted to identify all studies concerning diffuse gliomas and AYAs (15-39 years). We assessed epidemiology, clinical and imaging findings, histo-molecular characteristics, neurosurgical and neuro-oncological management, prognosis, and health-related quality of life. KEY MESSAGES: Diffuse gliomas remain the most frequent brain tumours in the AYA population. Symptoms mainly depend on the tumour location, which varies due to histo-molecular profiles. Specific imaging patterns of histo-molecular subtypes of diffuse gliomas are identified; however, no specific pattern related to the age group has been identified. The literature review favours optimizing the extent of surgical resection for diffuse gliomas, whichever the grade, and suggests a dedicated management for these patients. It seems more relevant to consider the treatment according to the histo-molecular profile of the diffuse glioma rather than the age group. Clinical trials will allow AYA patients to benefit from innovative therapies that could improve their outcome. This literature review suggests the need for a close and long-term psychological follow-up for AYA patients with brain tumour during the transitional care, during adulthood, as well as for their family members. Collaborative efforts are needed between paediatric and adult neurosurgical and neuro-oncological teams, to move forward in the therapeutic management of AYA patients harbouring diffuse gliomas.

BACKGROUND AND OBJECTIVES: Cerebral venous sinus thrombosis (CVST) after supratentorial craniotomy is a poorly studied complication, for which there are no management guidelines. This study assessed the incidence, associated risk factors, and management of postoperative CVST after awake craniotomy. METHODS: This is an observational, retrospective, monocentric analysis of patients who underwent a supratentorial awake craniotomy. Postoperative CVST was defined as a flow defect on the postoperative contrast-enhanced 3D T1-weighted sequence and/or as a T2* hypointensity within the sinus. RESULTS: In 401 supratentorial awake craniotomies (87.3% of diffuse glioma), the incidence of postoperative CVST was 4.0% (95% CI 2.5-6.4): 14/16 thromboses located in the superior sagittal sinus and 12/16 located in the transverse sinus. A venous sinus was exposed during craniotomy in 45.4% of cases, and no intraoperative injury to a cerebral venous sinus was reported. All thromboses were asymptomatic, and only two cases were diagnosed at the time of the first postoperative imaging (0.5%). Postoperative complications, early postoperative Karnofsky Performance Status score, and duration of hospital stay did not significantly differ between patients with and without postoperative CVST. Adjusted independent risk factors of postoperative CVST were female sex (adjusted Odds Ratio 4.00, 95% CI 1.24-12.91, P = .021) and a lesion ≤1 cm to a venous sinus (adjusted Odds Ratio 10.58, 95% CI 2.93-38.20, P < .001). All patients received standard prophylactic-dose anticoagulant therapy, and none received treatment-dose anticoagulant therapy. No thrombosis-related adverse event was reported. All thromboses presented spontaneous sinus recanalization radiologically at a mean of 89 ± 41 days (range, 7-171). CONCLUSION: CVST after supratentorial awake craniotomy is a rare event with satisfactory clinical outcomes and spontaneous sinus recanalization under conservative management without treatment-dose anticoagulant therapy. These findings are comforting to neurosurgeons confronted with postoperative MRI reports suggesting CVST.
