Performance of alterations of POSTN as early as C2 in early chemotherapy efficacy monitoring of BCa. A, B, POSTN levels at time-point of C0 and C2 in cases with in partial response (A) and non-partial response (B). C, change rate of POSTN at C2 was calculated by dividing the change level by the baseline level in cases with PR (n = 33) and Non-PR (n = 25) response
