Study Summary

This pilot study is a randomized, open-label, 2-arm active-controlled phase II clinical trial conducted at a single study site (UAMS). Subjects will be randomized to one of the 2 treatment arms and stratified by size of index lesion and number of brain metastases. The investigators will prospectively compare preoperative (neoadjuvant) SRS/SRT to postoperative (adjuvant) SRS/SRT in patients undergoing surgical resection for brain metastases. The investigators hypothesize that neoadjuvant SRS/SRT prior to surgical resection of brain metastases will result in improved freedom from Central Nervous System (CNS) events when compared to adjuvant SRS/SRT after surgical resection.

Primary Outcome

A CNS CE will consist of one of the following three events: Local Recurrence (LR) of the treated lesions, symptomatic radiation necrosis (SRN) to the treated lesions, or development of leptomeningeal disease (LMD).
