Refusal of Breast Surgery in Patients With Breast Cancer With a Clinical Complete Response (cCR) After Neoadjuvant Systemic Therapy and a Confirmed Pathological Complete Response (pCR) Using Vacuum-assisted Biopsy (VAB) and Sentinel Lymph Node Biopsy (SLNB)

Summary

The main goal of the study is to abandon breast surgery in patients with breast cancer with a clinical complete response (cCR) after neoadjuvant systemic therapy and confirmed pCR using Vacuum-assisted biopsy (VAB) and sentinel lymph node biopsy (SLNB). Evidence of the high diagnostic accuracy (sensitivity and specificity) of vacuum aspiration biopsy in determining pCR in patients with clinical complete response after neoadjuvant systemic therapy will allow abandoning breast surgery in favor of radiation therapy alone, improving the quality of life of these patients.
