Targeted sequencing and intracranial outcomes of patients with lung adenocarcinoma brain metastases treated with radiotherapy.

The results of the current study quantified the frequency of genetic aberrations in patients with AC-BMs and demonstrated their association with intracranial outcomes. In particular, a cohort of patients with KRAS mutations and ≥6 BMs were identified to be at high risk of requiring salvage WBRT after undergoing upfront stereotactic radiosurgery.
