Primary Outcome Measures
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
|---|---|---|
|
Rate of patients with change of primary treatment due to findings at additional CEM
Time Frame: Within two months after diagnosis of breast cancer
|
Mastectomy instead of partial mastectomy due to findings of multifocal disease, mastectomy instead of partial mastectomy due to larger unifocal extent, partial mastectomy instead of mastectomy due to improved demarcation of tumour area, bilateral surgery due to findings of contralateral cancer, primary neoadjuvant treatment instead of primary surgery due to more advanced disease
|
Within two months after diagnosis of breast cancer
|
