Comparison of marker expression between CR group and Failure group. The MDM2-positive rate of the Failure group was significantly higher than that of the CR group in cStageIII disease (P = 0.014). This was not seen in the overall group and in cStageI and cStageII cases (A). The Ki-67-positive rate of the CR group tended to be higher than that of the Failure group in cStageIII cases (P = 0.098), but it did not reach statistical significance. This was not seen in the overall cohort and patients with cStageI and cStageII (B).
