Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Screening for brain metastases using Computerised Tomography (CT scans).
The patients will have 3 monthly CT scans of the brain for 2 years and then 6 monthly for 2 years. This will be organised by the oncology team and will last around 20 minutes for the procedure and will be undertaken by the radiographers in imaging units in collaboration with the radiologists. These will happen at the time of the routine scans undertaken at the time other scans are done to evaluate response to treatment. The clinical trials team will, ensure that the scans are carried out at the appropriate times and monitored when in the study.. The patient will be in the study for 4 years.

Outcomes
Primary outcome [1] 339597 0
Incidence of screen-detected asymptomatic brain metastasis.
Timepoint [1] 339597 0
3 monthly for 2 years as the current data suggest that the brain metastases are commonly seen in the first 2 years. The scans will be undertaken 6 monthly for 2 years as the incidence of brain metastases decreases. The Primary Outcome will be assessed at the end of 4 years.
Secondary outcome [1] 441324 0
-Number of surgical resections
Timepoint [1] 441324 0
3 monthly for 2 years and 6 monthly for 2 years and overall outcome assessed at 4 years.
Secondary outcome [2] 441325 0
-Rate of stereotactic radiotherapy
Timepoint [2] 441325 0
3 monthly for 2 years and 6 monthly for 2 years and overall outcome assessed at 4 years.
Secondary outcome [3] 441326 0
-Progression free survival
Timepoint [3] 441326 0
CT scans 3 monthly for 2 years and 6 monthly for 2 years and overall outcome assessed at 4 years.
Secondary outcome [4] 441327 0
Overall survival
Timepoint [4] 441327 0
3 monthly for 2 years and 6 monthly for 2 years and overall outcome assessed at 4 years.

Type of endpoint/s
Statistical methods / analysis
Single-arm study of 45 patients to evaluate the acceptability and collect further information on incidence of brain metastases.
Total of 45 patients (including 10% drop-out) and will include (twenty TNB, twenty HER-2 and five ER+ patients. Assuming expected relapse overall 10 patients with TNB , 8 patients with HER-2 , and 5 patients with ER+ breast cancer will develop brain metastases.
