Immunohistochemistry expression patterns of patients treated with neoadjuvant chemotherapy. Samples were scored by percentage of cells staining positive for p53, TFAP2A, TFAP2C, and CD44 and compared in patients having a pCR (n = 4) versus a partial response (n = 19) to chemotherapy. Increased TFAP2C expression and decreased CD44 positivity were significantly associated with a pCR. TFAP2A and p53 expression were not associated with response to neoadjuvant chemotherapy. Horizontal bars represent the mean and error bars standard deviation. Data points with identical values are overlaid and each point might not be visible for all tests.
