CR, complete clinical response (no residual palpable disease); ER, estrogen receptor; MRD, minimal residual disease (residual palpable irregularity that was too small to be measured); n/a, not available; PgR, progestrogen receptor; PR, partial response (more than 50% reduction in bidimensional measurement); SD, stable disease (between 50% reduction and 25% increase in bidimensional measurement); RID, residual invasive disease; DCIS, ductal carcinoma in situ.
