Abstract:
A retrospective analysis was performed on 69 follow-up cases of ducal carcinoma in situ(DCIS) treated from Jan. 1981 to Dec. 1995 at Department of Surgery, Seoul National University Hospital. The results are as follows. The mean age was 45.4 years that ranged from 28 to 68. The proportion of DCIS to breast cancer was increased from 1.3% to 7.2% for 15 years. Clinical presentations of DCIS were mass, nipple discharge and suspicious mammographic findings. Patients presenting mass were decreased, while mammographically detected DCIS were increased. In 49.3% of cases, the tumor size was smaller than 2cm and in 21.3% of the cases, the tumor was not palpable. Treatment modality was changed to more conservative procedures. All of the patients survived well without local recurrence or distant metastasis for a mean follow-up of 36.3 months(range 7 to 146). Histopathologic review was also performed on 52 cases of which paraffin blocks were saved, by one pathologist and diagnosis was confirmed. Pure DCIS composed 16 cases(30.8%), and DCIS with microinvasion was 36 cases(69.2%). Clinical presentation of DCIS, such as age, nipple discharge, calcification on mammography and mass size were not related to the microinvasion, but mass palpability was related to microinvasion(p=0.018). There was no histopathologic features to predict progression to invasive carcinoma, regardless of comedo type, histologic grade and nuclear grade. The expression of cathepsin-D, nm23, p53 and c-erbB-2 protein, was also evaluated using immunohistochemical methods. The relationship between expression of immunohistochemical antibodies and prognostic variables such as tumor size, histologic grade, nuclear grade, and microinvasion was assessed. The overexpression of c-erbB-2 protein was associated with lower nuclear grade(p=0.033), and a strong correlation was seen between tumor size and cathepsin-D and p53 protein(p=0.035, p=0.016). In this study, we conclude that the fine classification and analysis of DCIS subtype, not only by histopathologic but also by immunohistochemical study can be helpful to predict biological behaviour of DCIS and decide the modality of treatment.
