Changes in SR, as monitored during and at the completion of neoadjuvant chemotherapy. (A) SRs for pathologically complete responders (RS5) and non–pathologically complete responders (RS1-4). Corresponding representative mastectomies (not shown) of responders and nonresponders demonstrate differences in the overall tumor morphology between response groups. (B) SRs for tumors with response scores 4-5, representing responders, and response scores 1-3, representing nonresponders. (C) SRs for tumors with response scores 3-5, representing responders, and response scores 1-2, representing nonresponders. * indicates statistical significance (P < .05) and ** indicates statistical significance (P < .001).
