Measure Description: The clinical stage at initial diagnosis in breast cancer is typically described using the TNM staging system, which takes into account the size of the primary tumor (T), whether the cancer has spread to nearby lymph nodes (N), and whether it has metastasized (spread to distant organs or tissues) (M). The stage is described as Roman numerals from 0 to IV, with higher numbers indicating a more advanced stage of cancer.

1.Primary Outcome
Title Confirmed Overall Response Rate in CNS
Hide Description The proportion of patients who had confirmed complete response or confirmed partial response, assessed using neuro-oncology-brain metastases (RANO-BM) criteria. RANO-BM assess the response of brain metastases to treatment, using MRI scan. There are four categories as results: Complete Response (CR), Partial Response (PR), Stable Disease (SD), and Progressive Disease (PD), which is separately defined as disappearance of all target lesions, at least a 30% decrease in the sum of the diameters of target lesions, neither sufficient shrinkage to qualify as PR nor sufficient increase to qualify as progressive disease (PD) and at least a 20% increase in the sum of the diameters of target lesions, taking as reference the smallest sum on study (including the baseline sum if that is the smallest) or the appearance of one or more new lesions.
Time Frame Participants were evaluated for response every 6 weeks for the first 24 weeks and then every 9 weeks thereafter, through study completion, an average of 24 weeks

Title Patient Reported Outcomes by MDASI-BT Stratified by CBR at 18 Weeks
Hide Description

Evaluated by M.D. Anderson Symptom Inventory Brain Tumor (MDASI-BT). MDASI-BT assess 13 symptom items and 6 interference items from the core MDAST as well as 9 symptoms specific to brain tumors, and generate Symptom Severity Score (SSS) and Symptom Interference Score (SIS) separately. The scale of the scores are in a range of 0 to 10, where 0 represents "not present" or "not severe," and 10 represents "as bad as you can imagine" or "most severe." A higher score indicates a higher level of symptom severity.

Mean of the scores are reported across groups with and without CBR at 18 weeks and in baseline, week 9 and week 24.
