Early dynamics of markers in BCa patients treated with chemotherapy regimens. A–C, representative CT images of three partial-response cases at time-point of C0 and C4. Tumor lesions before and after the treatment were indicated by arrows. D-F, dynamics of POSTN (D), CA15-3 (E) and CEA (F) in the three representative cases at time-point of C0, C2 and C4. G-I, the dynamics of the POSTN (G), CA15-3 (H) and CEA (I) in longitudinal assessment of all 58 patients annotated with the tumor early response status to chemotherapy at C0 and C4. PR partial response (n = 33), Non-PR non-partial response (n = 25)
