Brief Summary:

Chemotherapy in clinically node positive breast cancer patients is increasingly administrated in a neoadjuvant setting. The standard treatment regimen in these cases is then: neoadjuvant chemotherapy (NAC) followed by breast surgery and an axillary lymph node dissection (ALND). NAC results in axillary pathologic complete response (pCR) in 1 out of 3 patients, indicating a complete absence of axillary metastases after completion of NAC. In such events, ALND can be regarded as overtreatment that creates unnecessary morbidity. Less invasive axillary surgery which can accurately assess axillary pCR is therefore preferred over standard ALND in all patients. In case of detection of remaining axillary lymph node metastases by this less invasive axillary surgical procedure, completion axillary treatment is standard of care.

The novel RISAS procedure is introduced as a possible less invasive axillary staging procedure. RISAS procedure contains Radioactive Iodine Seed localisation in the Axilla in axillary node positive breast cancer combined with a Sentinel node procedure. The iodine seed in the axillary lymph node metastasis will be placed prior to start of NAC.

Arm Intervention/treatment
Experimental: RISAS
All patients will undergo RISAS procedure, followed by axillary lymph node dissection in a one-step surgical procedure.
Procedure: RISAS
RISAS procedure contains Radioactive Iodine Seed localisation in the Axilla in axillary node positive breast cancer combined with a Sentinel node procedure.




Primary Outcome Measures :
  1. Identification rate and accuracy (sensitivity, negative predictive value (NPV) and false negative rate (FNR)) of RISAS-procedure for identifying axillary pCR, with 95% confidence intervals will be calculated. [ Time Frame: Participants will be followed from the moment of first out-hospital clinic visit untill final breast surgery, an expected average of 4 months. ]

Secondary Outcome Measures :
  1. The identification rate and accuracy (sensitivity, NPV and FNR) of both techniques used in RISAS-procedure (i.e. SLNB and MARI) for identifying axillary pCR, will be calculated separately as well. [ Time Frame: Participants will be followed from the moment of first out-hospital clinic visit untill final breast surgery, an expected average of 4 months. ]
