title: [Extensive intraductal components of invasive ductal breast carcinoma--value of mammography].
abstract: The presence of an extensive intraductal component (EIC) in patients with infiltrating ductal carcinoma is a major factor for predicting local recurrence after breast-conserving surgery and radiotherapy. A retrospective study including 67 consecutive cases of stage I and II infiltrating ductal carcinomas of the breast was conducted to determine the predictive values of mammographic features associated with the presence or absence of EIC. 43% of the lesions contained a pathologically verified EIC. 63% (25/40) of lesions showing mammographic evidence of calcifications with or without a mass were associated with an EIC. In contrast, only 17% (4/24) of carcinomas without calcifications demonstrated an EIC. This difference was statistically significant (p < 0.001). Lesions with calcifications greater than 3 cm in extent were significantly (p < 0.01) more likely to have an EIC (8/9; 89%) than those with calcifications less than 3 cm in extent (17/31; 55%). Furthermore, no patient with a palpable mass who had normal findings on mammograms was diagnosed to have an EIC.
