Radiotherapy for brain metastases: ASTRO updates guidelines


 

FROM PRACTICAL RADIATION ONCOLOGY

For patients with resected brain metastases:

  • Radiation therapy is recommended for all patients after resection in order to improve intracranial control.
  • For patients with limited brain metastases after resection, postoperative SRS is recommended over WBRT to preserve the patient’s neurocognitive function and quality of life.
  • As a potential alternative to SRS postresection, SRS prior to brain metastasis resection is conditionally recommended.

Updating the guidelines

ASTRO emphasizes that the scope of this paper is limited to the radiotherapeutic management of intact and resected brain metastases resulting from nonhematologic solid tumors. It provides guidance on the reasonable use of modern radiation therapy strategies, including single-fraction and fractionated (ie, hypofractionated SRS) SRS and HA-WBRT, and also discusses clinical considerations in selecting the optimal radiation therapy strategy or in deferring it in favor of best supportive care or close neuro-oncologic surveillance.

The authors note, however, that beyond the scope of this guideline, there are many other important questions that may be the subject of other guidance, such as the appropriate role for CNS-active systemic therapies and/or surgical intervention.
