Abstract
PDF Background Although core needle biopsy (CNB) is considered to be the standard technique for histological diagnosis of breast lesions, it is less reliable for diagnosing atypical ductal hyperplasia (ADH). We therefore assessed the characteristics of CNB-diagnosed ADH that are more likely to be associated with more advanced lesions on subsequent surgical excision.
Methods We retrospectively examined 239 consecutive CNBs, 127 of which were diagnosed as ADH following surgical excision, performed at Asan Medical Center between 1995 and 2010. Archival slides were analyzed for the number of cores per specimen, the number of ADH foci, and the ratio of ADH foci to number of cores (FC ratio).
Results We found that ADH foci in 3 or more cores (p=0.003) and the presence of ADH in 3 or more foci (p=0.002) were correlated with malignancy following excision lesion. Moreover, an FC>1.1 was significantly associated with malignancy in the subsequent excision (p=0.000).
Conclusions Including the number of ADH foci, the number of cores involved according to ADH, FC ratio, and histologic type in a pathology report of CNB may help in making clinical decisions about surgical excision.

Abstract

- Status of margins and the size of the lesion are independent prognostic factors of ductal carcinoma in situ (DCIS). Histologic grading of DCIS and expression of biologic marker also appear to act as prognostic factors. However, DNA ploidy analysis using flow cytometry in the DCIS and atypical ductal hyperplasia (ADH) has been rarely reported, and the biologic behavior of ADH is unknown. We performed immunohistochemical staining and DNA ploidy analysis using flow cytometry on 45 cases of pure DCIS without microinvasion and 34 cases of ADH to compare the expression of biologic markers and DNA ploidy patterns according to the histologic grade of DCIS, to evaluate the usefulness of the Van Nuys classification, and to investigate the biologic behavior of ADH and low grade DCIS. A total of 41.9% of DCIS and 32.1% of ADH were detected mammographically in asymptomatic patients. The most common subtype of the high grade DCIS was comedo type (56.3%), while the low and intermediate grade DCIS were cribriform type. Expression of ER, c-erbB-2 and Ki-67 proliferative index (PI) was significantly associated with nuclear grade and histologic grade of DCIS. Expression of c-erbB-2 was also significantly correlated with presence of necrosis. In low grade DCIS, Ki-67 PI was significantly higher than ADH. A total of 63.6% of DCIS and 70% of ADH were diploidy and 15.9% of DCIS was aneuploidy. There was no aneuploidy in ADH. No significant association was noted between DNA ploidy and histologic grade or nuclear grade. However, in high grade DCIS, the frequency of aneuploidy was high. In conclusion, histologic grading of DCIS employing nuclear grade and necrosis is a useful tool accounting for biologic behavior. High grade DCIS and comedo DCIS impart aggressive biologic behavior and suggest a higher possibility of local recurrence or progression to invasive carcinoma. In the differential diagnosis of ADH and low grade DCIS, the use of Ki-67 PI and DNA ploidy analysis by flow cytometry will be helpful for accurate diagnosis and prediction of biologic behavior.

Abstract
PDF
- Mutation of the p53 gene is one of the most common genetic alterations in invasive breast carcinoma. However, it is unclear that the mutation usually occurs in noninvasive breast lesions. It might be expected that there is a correlation between histologic progression of breast lesions and proliferative rate. We investigated the expression of p53 protein and Ki-67 labelling index (LI) using immunohistochemistry in 16 ductal carcinoma in situ with microinvasion (DCIS-Mi), 56 DCIS, 15 atypical ductal hyperplasia (ADH), and 7 intraductal hyperplasia (IDH). Expression of p53 protein was detected in 33.9% of DCIS and 56.3% of DCIS-Mi and was confined exclusively in Van Nuys DCIS group 2 and 3. In ADH and IDH, no expression of p53 protein was found. There was no significant correlation between Van Nuys DCIS groups and Ki-67 LI. In conclusion, p53 mutation may be involved in the neoplastic progression from ADH to DCIS and is directly related to high nuclear grade and associated necrosis of DCIS.
