Narrative review of palliative hypofractionated radiotherapy for high grade glioma

Abstract: High grade gliomas (HGG) include World Health Organization (WHO) grade III anaplastic astrocytoma (AA) and WHO grade IV glioblastoma (GBM). As genomic alterations are prognostic, even WHO grade II, IDH-wildtype gliomas may be considered as HGG. Current management of HGG include best supportive care (BSC), surgery, radiation therapy (RT), chemotherapy, and a combination. Elderly patients (defined here as age ≥65) with GBM have significantly worse survival compared to younger patients.Similarly, patients with po… Show more

“…As yet another confirmation, the expected improved survival has been observed in elderly patients treated with RT in comparison with those receiving the best supportive care alone, with similar survival for patients undergoing conv-FRT (60 Gy/30 fractions) and hypo-FRT (25-40 Gy in 5-15 daily fractions) [87]. Hence, while it has an undeniable role in improving cancer survival, RT has also various negative effects, ranging from mild to severe and including IR-induced meningioma, IR-induced glioma, cavernous malformation, enlarging perivascular spaces, leukoencephalopathy, stroke-like migraine after RT, Moyamoya syndrome, radiation necrosis, IR-induced labyrinthitis, optic neuropathy, retinopathy, and others [88].…”

“…Despite advances in neurosurgery and the widespread use of chemotherapy and radiotherapy against newly diagnosed GBM, patient survival has improved only marginally. Radiotherapy is the primary treatment strategy for advanced glioma ( 25 , 26 ), although its outcomes are limited due to hypoxia-induced resistance. HIF-1α is activated in the hypoxic microenvironment of solid tumors, and promotes tumor cell survival by increasing glucose uptake and utilization.…”

“…Glioma therapies mainly consist of surgical excision combined with radiotherapy and chemotherapy (3)(4)(5)(6). Patient survival rates are very low despite surgery in combination with postoperative chemotherapy and radiotherapy (1,3,4,6,7). Thus, new therapies for treatment of glioma are urgently needed.…”
