Is mastectomy with immediate reconstruction safe for patients undergoing neoadjuvant chemotherapy? A nationwide study from Korean Breast Cancer Society.

In the pCR group, the prognoses of patients who underwent mastectomy with IBR were not different from those of patients who underwent mastectomy. In the non-pCR group, women in the mastectomy with IBR group had shown worse prognoses than the mastectomy group in advanced clinical stage. Appropriate operation should be determined depending on the status of individualized patients.
