Abstract PS6-54: Prognostic significance of residual micrometastatic axillary involvement with complete pathologic breast response after neoadjuvant chemotherapy for early breast cancer
Abstract:Introduction and objectives Pathologic complete response (pCR, ypT0/Tis ypN0) after neoadjuvant chemotherapy (nCT) in early breast cancer (BC) is associated with higher survival rate. Controversy about the prognostic significance of low-volume or micrometastatic axillary residual disease (ypN1mi-RD) exists. Essentially, it is considered equivalent to high-volume nodal disease (ypN1/ypN2-RD) for the indication of lymphadenectomy after nCT. Clarifying ypN1mi-RD prognostic value would be useful for planning adjuv… Show more
