Abstract
Purpose: Hypofractionated short-course radiation therapy (SCRT) is an alternative treatment option for elderly or frail patients with newly diagnosed glioblastoma (GBM) post-surgery. This study compares survival outcomes and treatment costs between patients receiving SCRT and those undergoing standard long-course radiation therapy (LCRT).
Methods: This retrospective study utilized health insurance claims and national cancer registry data from Korea to compare overall survival (OS) and treatment costs between patients receiving SCRT and LCRT across all ages and sub-group analysis within the subgroup of cases aged 65 and older from 2016 onwards, a period when intensity-modulated radiotherapy (IMRT) was widely adopted.
Results: A total of 1,598 patients were included. Median OS since the first day of radiation therapy was 10.4 months (95% CI [9.6; 12.8]) for SCRT (n = 197) versus 16.2 months (95% CI [15.5; 16.9]) for LCRT (n = 1401) respectively. Subgroup analysis using stabilized inverse probability of treatment weighting (S-IPTW) showed indicating non-inferiority in elderly patients in median OS for elderly patients (≥ 65) with 10.6 months (95% CI [8.9; 14.0]) for SCRT (n = 147) versus 13.2 months (95% CI [8.9; 14.0]) for LCRT (n = 541). The median treatment cost of SCRT is about 6,000 USD lower, 25% less than LCRT. Compliance with the standard TMZ regimen post-radiation improved OS across all age groups.
Conclusion: Considering comparable OS and shorter treatment duration, SCRT offers a viable, cost-effective option for elderly GBM patients. Adhering to standard TMZ also contributes to OS improvement. Further research reflecting key prognostic factors is essential to refining the role of SCRT.
期刊介绍：
The Journal of Neuro-Oncology is a multi-disciplinary journal encompassing basic, applied, and clinical investigations in all research areas as they relate to cancer and the central nervous system. It provides a single forum for communication among neurologists, neurosurgeons, radiotherapists, medical oncologists, neuropathologists, neurodiagnosticians, and laboratory-based oncologists conducting relevant research. The Journal of Neuro-Oncology does not seek to isolate the field, but rather to focus the efforts of many disciplines in one publication through a format which pulls together these diverse interests. More than any other field of oncology, cancer of the central nervous system requires multi-disciplinary approaches. To alleviate having to scan dozens of journals of cell biology, pathology, laboratory and clinical endeavours, JNO is a periodical in which current, high-quality, relevant research in all aspects of neuro-oncology may be found.
