TFDP3 and ductal breast carcinoma in situ: As for the histological types (p = 0.131), we found that the rate of TFDP3 expression was 39.86% in invasive ductal carcinoma (57 in 143 cases), but that TFDP3 was not expressed in invasive lobular carcinoma (0 in 4 cases), mucinous carcinoma (0 in 2 cases) or intraductal carcinoma (0 in 1 cases) (Fig 5C).
