Brief Summary

Breast surgery may be overtreatment when there is a complete response to systemic neoadjuvant treatment as determined clinically and by imaging. However the reliability of imaging techniques (ultrasound, mammography and magnetic resonance) in identifying complete response varies in published studies and surgery remains the preferred method of detecting residual disease. The aims of this study are:

  1. 1.To assess the reliability of minimally invasive preoperative image-guided vacuum-assisted biopsy (VAB) in identifying residual breast in cT1-cT2-cT3, cN0-cN1 breast cancer patients, either with complete clinical/radiological response, or with residual breast disease \<1 cm, after systemic neoadjuvant treatment.
  2. 2.To assess the reliability of minimally invasive preoperative image-guided needle biopsy in identifying residual axillary disease in cT1-cT2-cT3, cN0-cN1 breast cancer patients, either with complete clinical/radiological response, or with residual breast disease \<1 cm, after systemic neoadjuvant treatment.

Outcome Measures

Primary Outcomes (1)

  • Evaluation of the accuracy of histological examination of the breast VAB performed pre-surgery

    Identification of percentage of cases with correspondence between pre-operative VAB findings in breast with histological findings after quadrantectomy or mastectomy in patients with complete radiological response after neoadjuvant chemotherapy.

    40 days

Secondary Outcomes (1)

  • Evaluation of the accuracy of histological examination of the lymph node biopsy performed pre-surgery

    40 days

Study Arms (1)

minimally invasive preoperative image-guided vacuum-assisted biopsy

cT1-cT2-cT3 cN0-cN1 breast cancer patients, either with clinical/radiological complete response, or with \<1 cm residual breast disease after systemic primary treatment, undergo preoperative image-guided breast VAB with 9-gauge needle. Patients who are cN1 before systemic primary treatment undergo removal of the tagged axillary nodes. In both cases the aim is to identify any residual disease. Conservative breast surgery or mastectomy will be performed in all patients after multidisciplinary clinical evaluation. Surgically confirmed residual tumor will be compared to VAB result.

Device: minimally invasive preoperative image-guided vacuum-assisted biopsy

Interventions

minimally invasive preoperative image-guided vacuum-assisted biopsy of the breast and needle biopsy of axillary lymph node

Also known as: needle biopsy
minimally invasive preoperative image-guided vacuum-assisted biopsy
