Radiation-induced meningioma growth rate and clinical outcomes


  • Radiation-induced meningiomas (RIM) have a high growth rate, are usually symptomatic, and likely to progress after surgical resection.

Why this matters ?

  • Meningiomas are the most common tumors following cranio-spinal radiotherapy and is increasingly seen more often as a result of improved cancer survival rates. There is currently no standard management of RIM.

  • Although surgery seems to be the most common intervention following RIM in this study, the high growth rate of these tumors may cause clinical and radiological progression.
