Purpose
The primary aim of the study is to evaluate the 5 yr locoregional recurrence rate (LRR) in cT1-2cN1(cytology/histology and/or positive SN, excluding patients with > 3 pathologic axillary nodes on ultrasound or MRI) breast cancer patients, treated with neo-adjuvant chemotherapy, breast surgery, and radiotherapy that is protocolised based on the pathology findings after chemotherapy and definitive surgery (ypTNM stage).

- locoregional recurrence rate [ Time Frame: 5 Yr ] [ Designated as safety issue: No ]to evaluate the 5 yr locoregional recurrence rate (LRR) in cT1-2cN1(cytology/histology and/or positive SN, excluding patients with > 3 pathologic axillary nodes on ultrasound or MRI) breast cancer patients, treated with neo-adjuvant chemotherapy, breast surgery, and radiotherapy that is protocolised based on the pathology findings after chemotherapy and definitive surgery (ypTNM stage).
- risk model based on rick factors [ Time Frame: 5 yr ] [ Designated as safety issue: No ]to develop a risk model based on risk factors, that can be used to predict which of the patients with a cT1-2cN1 breast carcinoma, treated with neoadjuvant chemotherapy and surgery, have a 5 yr LRR > 8 % if radiotherapy is withheld.

Show Detailed Description
Eligibility| Genders Eligible for Study: | Female |
| Accepts Healthy Volunteers: | No |
| Sampling Method: | Probability Sample |
patients with cT1-2cN1(cytology/histology and/or positive SN, excluding patients with > 3 pathologic axillary nodes on ultrasound or MRI) breast cancer, treated with at least three cycles of chemotherapy followed by breast and axillary surgery are eligible for the study.
Inclusion Criteria:
- cT1-2 invasive breast cancer, with one or more pathologically proven tumour positive axillary lymph nodes (either by sentinel node biopsy, ultrasound/palpation guided biopsy or fine needle aspiration)
- At least 3 cycles of neoadjuvant chemotherapy have been given (irrespective of the regimen)
- No standard axillary lymph node dissection is performed prior to chemotherapy
- Axillary lymph node dissection performed after chemotherapy
Exclusion Criteria:
- cT3-T4 invasive breast cancer prior to any treatment
- cN2-3 prior to any treatment, or > 3 or less pathological nodes on ultrasound or MRI
- More than focally irradical surgery and breast conserving therapy
