Stereotactic radiosurgery alone versus resection plus whole‐brain radiotherapy for 1 or 2 brain metastases in recursive partitioning analysis class 1 and 2 patients

Abstract

SRS alone appeared to be as effective as resection plus WBRT in the treatment of 1 or 2 brain metastases for patients in RPA class 1 and 2. Patient outcomes were associated with age, Karnofsky performance status, number of brain metastases, extracranial metastases, RPA class, and interval from tumor diagnosis to treatment.
