Postoperative stereotactic radiosurgery for resected brain metastasis

Area of Science:

• Neuro-oncology
• Radiation Oncology
• Neurosurgery

Background:

• Brain metastasis significantly impacts patient prognosis despite treatment advances.
• Standard adjuvant therapy post-surgical resection often involves whole brain radiation therapy (WBRT).
• WBRT is associated with significant neurotoxicity, prompting a search for alternatives.

Purpose of the Study:

• To review the current literature on the efficacy of postoperative stereotactic radiosurgery (SRS) for resected brain metastasis.
• To evaluate the toxicity profile of postoperative SRS in this clinical setting.
• To compare SRS with WBRT as an adjuvant treatment following surgical resection.

Main Methods:

• Systematic review of studies investigating postoperative SRS for brain metastasis.
• Analysis of data regarding tumor control rates and overall survival.
• Assessment of neurotoxicity and adverse events associated with SRS.

Main Results:

• Postoperative SRS demonstrates promising tumor control rates in patients with resected brain metastasis.
• SRS may offer a reduced risk of neurotoxicity compared to WBRT.
• Evidence suggests SRS can be a viable alternative to WBRT in select patients.

Conclusions:

• Postoperative SRS is an effective and potentially less toxic treatment option for patients with resected brain metastasis.
• Further research is warranted to establish optimal SRS protocols and long-term outcomes.
• The findings support a shift towards considering SRS over WBRT in the adjuvant setting.
