  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).


Condition Intervention
Breast Cancer
Radiation: no radiotherapy
Radiation: radiotherapy of the thoracic wall
Radiation: radiotherapy of thoracic wall/breast AND supraclavicular nodes

Study Type: Observational

Primary Outcome Measures:
  • 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).


Secondary Outcome Measures:
  • 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.

  • 10 year LRR [ Time Frame: 10 Yr ] [ Designated as safety issue: No ]
    10 year Locoregional Recurrence Rate

  • 5 Yr overall survival rate [ Time Frame: 5 yr ] [ Designated as safety issue: No ]
    and 5 yr overall survival rates.

  • 10 Yr overall survival rate [ Time Frame: 10 yr ] [ Designated as safety issue: No ]
    and 10 yr overall survival rates.

  • 15 Yr overall survival rate [ Time Frame: 15 yr ] [ Designated as safety issue: No ]
    and 15 yr overall survival rates.

Groups/Cohorts Assigned Interventions
Group 1: ypT0-2N0 Radiation: no radiotherapy

  Eligibility

Genders Eligible for Study:   Female
Accepts Healthy Volunteers:   No
Sampling Method:   Probability Sample
Study Population

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.

Criteria

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:
