Summary
Brief summary (as posted)
The purpose of this study is to investigate if sentinel lymph node biopsy is a reliable staging tool for breast cancer patients planned for neoadjuvant chemotherapy (=before breast surgery) and if, in that case, it is safe to omit axillary lymph node dissection if the sentinel lymph node is free of metastasis.

Arms and outcomes
Arms (0)
[]Primary outcomes (1)
- measure
- False negative rate
- timeFrame
- Up to two years
- description
- The rate of patients with no metastasis/ses in their sentinel lymph node/s before neoadjuvant chemotherapy (NAC) but metastasis/ses in the nodes from the axillary lymph node dissection performed after NAC will be analysed. In substudy II we also investigate the false negative rate in sentinel lymph node biopsies performed after NAC if the patient had positive lymph nodes at diagnosis.
Secondary outcomes (1)
- measure
- Identification rate
- timeFrame
- Up to two years
- description
- The number of successful sentinel lymph node biopsies among the total number of attempted biopsies. Will be analyses both before and after neoadjuvant chemotherapy.
