Abstract
Background Studies report conflicting evidence regarding the existence of a DCIS-associated premalignant pathway in BRCA mutation carriers. We aimed to examine the prevalence, phenotype, and expression of oncodrivers in pure DCIS (pDCIS) and invasive breast cancer with concurrent DCIS (IBC + DCIS) in mutation carriers. Methods A cohort of BRCA1 and BRCA2 mutation carriers >18 years old who underwent surgery for breast cancer at an academic hospital (1992–2011) and had pathology available for review were included for study. Invasive breast cancer (IBC) and DCIS were stained for ER, PR, HER1, HER2, and HER3, and C-MET. DCIS prevalence was evaluated. Correlation of IBC and DCIS phenotypes was evaluated in patients with IBC + DCIS. DCIS and IBC expression of tumor markers were examined by BRCA mutation. Results We identified 114 breast tumors. Of all BRCA1-associated tumors, 21.1 % were pDCIS and 63.4 % were IBC + DCIS. Of all BRCA2-associated tumors, 23.3 % were pDCIS and 60.5 % were IBC + DCIS. In BRCA1 and BRCA2 mutation carriers with IBC + DCIS, there was a significant correlation in ER, PR, and HER3 expression between the DCIS and IBC components. Most BRCA1-associated DCIS did not express ER, PR or HER2, while most BRCA2-associated DCIS did express ER and PR. BRCA1− as well as BRCA2-associated DCIS had expression of HER3 and C-MET. Conclusions The majority of BRCA-associated tumors had DCIS present. Concordance of DCIS and IBC phenotypes was high, arguing for the existence of a DCIS-associated premalignant pathway. Oncodrivers HER3 and C-MET were expressed in the DCIS of mutation carriers, suggesting an opportunity for prevention strategies.

Abstract
Patients with human epidermal growth factor receptor 2 (HER2neu)-positive breast invasive cancer are known to have larger, more aggressive tumors. Little research exists on the relationship between HER2neu status and extent of ductal carcinoma in situ (DCIS). A retrospective review of a single-institution database was performed for patients with DCIS between the years 2002 and 2011. A single blinded breast radiologist reviewed preoperative imaging. Pathology was reviewed for extent of DCIS. Primary outcome was mastectomy. Multivariate logistic regression was used to determine adjusted mastectomy risk. There were 166 cases, 34 HER2neu-positive. HER2neu receptor-positive patients had larger lesions on imaging: 4.0 versus 2.7 cm, by 2.9 versus 1.5 cm ( P = 0.0499 and 0.0182). HER2neu-positive patients with DCIS were more likely than HER2neu-negative to undergo mastectomy than lumpectomy (53 vs 28%, P = 0.006). Pathology revealed a trend toward larger lesions in HER2neu-positive patients (2.96 vs 2.22 cm, nonsignificant). Patients with HER2neu-positive disease were three times more likely to undergo mastectomy (odds ratio, 2.9; 95% confidence interval, 1.23 to 6.78). Patients with HER2neu-positive DCIS had greater extent of disease by imaging and were more likely to undergo mastectomy than HER2neu-negative. These findings will help surgeons counsel patients on surgical treatment.

Abstract
Background Microinvasive ductal carcinoma in situ of the breast is a rare entity defined as ductal carcinoma in situ with invasive foci measuring no more than 1 mm. In general, the outcome is excellent, similar to ductal carcinoma in situ. We report a patient with breast ductal carcinoma in situ with microinvasion who died eight months after diagnosis due to progression of the disease – liver metastases. This is the first report in the literature of such an aggressive course. Case presentation A 47-year-old Caucasian woman presented with mammographic-detected suspicious microcalcinations in an area of 8.6 x 6 cm. A radical mastectomy with a sentinel lymph node biopsy and immediate breast reconstruction with implant was performed. A histopathological report showed a massive high grade ductal carcinoma in situ, of the solid and comedo type. In one quadrant, some foci of microinvasions of less than 1 mm were present. Tumour margins were free. Isolated tumour cells were found in the sentinel lymph node. Hormone receptors were negative and human epidermal growth factor receptor-2 status was not performed. The patient received no adjuvant systemic therapy. Eight months after the surgery, she died from hepatic failure without known breast cancer progression before. An autopsy revealed diffuse liver metastases with human epidermal growth factor receptor 2-positive, hormone receptor negative breast cancer. Dissemination to other organs was not proven. Conclusion Our patient is a rare case of ductal carcinoma in situ with microinvasion that developed distant metastases very early. In case of multiple foci of microinvasion, besides radical local treatment we suggest considering adjuvant systemic treatment based on biological characteristics since tumour size alone does not predict the prognosis well.

Abstract
Although positron emission tomography (PET) using [(18)F]fluorodeoxyglucose (FDG) has an established role in breast cancer staging and monitoring response to therapy, more specifically novel targeted tracers are under investigation and hold promise toward identification of critical molecular targets of therapy. We review herein novel tracers in breast cancer including steroidal endocrine tracers, 16α-[(18)F]fluoro-17β-estradiol (FES) to measure tumor estrogen receptor density and function and 21-(18)F-fluoro-16α,17α-[(R)-(1'-α-furylmethylidene)dioxy]-19-norpregn-4-ene-3,20-dione (FFNP) to assay tumor progesterone receptor (PgR) expression, and to asses nuclear proliferation using 3'-deoxy-3'-fluorothymidine (FLT), membrane lipids using (11)C- or (18)F-labeled choline and amino acid transport using (11)C-methionine. These investigational tracers are moving closer to clinical use, and are likely to affect clinical care by aiding in characterization of breast cancer biology, which can have an important effect in the selection of targeted therapy and monitoring responsiveness to such therapy.

Abstract
Preoperative breast MRI in newly diagnosed cancer patients has several potential benefits. Improved survival for patients with invasive disease as the index lesion is unlikely to be one of these benefits, given what is known from variations in locoregional management in the historic conservation trials. However, this may not be the case for patients with ductal carcinoma in situ (DCIS), as the discovery of unsuspected invasive cancer located elsewhere from the biopsy-proven DCIS could result in decreased survival if left undetected and untreated. In support of this hypothesis, a previous observational study of a large cohort of DCIS patients revealed the development of invasive cancer to be the most common event after unilateral DCIS treatment, occurring in 3.9%, mostly in the opposite breast. These cancers appeared on mammography or clinical exam within a short time frame (median 2.9 years) and were associated with a diminution in survival. Given these second events occurring so soon after DCIS treatment, it must be considered that invasive cancers were present elsewhere, but mammographically occult, at the time of DCIS diagnosis. To examine this possibility, 288 consecutive patients with newly diagnosed DCIS underwent preoperative MRI, with the discovery of separate foci of invasive cancer, either multicentric or contralateral, occurring in 3.5% of patients, a similar incidence to the short-term observational study. These "elsewhere" invasive cancers are presented here with details of pathology such that both Stage I and Stage II disease can be seen as clinically significant, with the usual stage-based survival implications.

Abstract
PURPOSE Preclinical data indicate that the combination of docetaxel, cisplatin and trastuzumab (TCH) may have the potential for clinically significant activity against breast cancers that overexpress the her2/neu gene (HER2). An open-label phase II trial was designed to investigate the response rate and toxicity profile of TCH in breast cancer patients with a primary tumor 2-5 cm in diameter (T2) in its original size. METHODS Thirty breast cancer patients with HER2-overexpressing tumors were enrolled. Patients received 6 cycles of docetaxel at 60 mg/m(2) and cisplatin at 50 mg/m(2) given on day 1 and then every 21 days. Trastuzumab was given on day 1, cycle 1 (4 mg/kg), and then continued weekly at 2 mg/kg for 1 year or until disease progression. Tumor measurements were obtained at baseline as well as after 3 and 6 cycles of chemotherapy. RESULTS We identified 29 breast cancer patients in Taiwan, of whom 13 (44.8%) had pathological complete responses. No cardiac toxicity was observed. Hematologic grade 4 or 3 toxicities were observed in 1 of 28 patients. Non-hematologic grade 4 or 3 toxicities with a reverse pattern were observed in 6 of 29 patients. CONCLUSIONS The results of our study indicate that TCH neoadjuvant chemotherapy is feasible and active in T2 HER2-overexpressing breast cancer patients in terms of pathological complete response rate, complete response, partial response and manageable toxicities.

Abstract
Pathologic complete response (pCR) after NC has been consistently associated with improved outcomes. Residual DCIS after NC does not portray worse prognosis compared to complete eradication of all disease but has clinical implications regarding surgical management. We report a case of pCR of DCIS associated with invasive carcinoma in an HER-2 + tumor after NC plus trastuzumab despite persistence of malignant-appearing microcalcifications mammographically. A 41-year-old Caucasian female presented with a 4 × 4 cm mass in the right breast and a 2.5 cm right axillary node. Mammogram showed a 2.5 cm mass and a 12 cm area of linear pleomorphic, suspicious calcifications in the upper part of the breast. Core biopsy revealed invasive ductal carcinoma and DCIS associated with calcifications (ER 85%, PR 6%, Her2neu 3+ by IHC). Axillary node FNA was positive for malignancy. The patient received doxorubicin/cyclophosphamide (AC) → paclitaxel plus T with complete clinical and radiologic response but no significant change in the microcalcifications. Final pathology showed no residual invasive carcinoma or DCIS despite the presence of numerous ducts with microcalcifications. Documented eradication of DCIS has not been reported following NC when malignant-appearing calcifications persist and this observation may have important clinical implications regarding surgical management.

Abstract
The incidence of ductal carcinoma in situ (DCIS) has increased because of increasing use of sensitive imaging modalities. MRI is commonly used for the detection of breast cancer but has not yet been validated in randomized trials. There have not been randomized trials addressing optimal margins of excision or axillary sampling. Whole breast radiation after lumpectomy decreases the risk of recurrence but may be omitted in selected patients. Adjuvant Tamoxifen reduces the risk of recurrence but has no impact on overall survival rates.

Abstract
INTRODUCTION Biologic markers that predict development of invasive breast cancer (IBC) in patients diagnosed with ductal carcinoma in situ (DCIS) are needed to improve personalized therapy. In this study, we examined the incidence of early IBC in DCIS subgroups defined by immunophenotype. METHODS Clinical and histologic materials of 143 patients with radiographically suggesting DCIS without obvious evidence of IBC were reviewed. All patients underwent initial biopsy followed by short-term subsequent resection. The presence of IBC, histopathologic features of DCIS and IBC, when present, and their estrogen receptor (ER), progesterone receptor (PR), and HER2 phenotypes were evaluated. RESULTS Early IBC was identified on initial biopsy in 6 (4%) and subsequent resection in 24 (17%) patients. HER2 positivity in DCIS was the dominant factor associated with IBC. There was also a significant association between ER/PR/HER2+ DCIS and the presence of IBC. The ER/PR/HER2+ DCIS appeared to be the most unstable precursor, because of the highest invasion rate and frequent association with a discordant phenotype. CONCLUSIONS HER2 positivity and ER/PR/HER2 phenotype may be used to identify DCIS patients at higher risk of harboring or potentially developing IBC. Strategies targeting HER2 in DCIS may be of potential benefit in preventing IBC in patients with DCIS.

Abstract
Recent advances in the study of the tumor microenvironment have revealed significant interaction between tumor cells and their surrounding stroma in model systems. We have previously shown that two distinct stromal signatures derived from a macrophage (CSF1) response and a fibroblastic (DTF-like) response are present in subsets of invasive breast cancers and show a correlation with clinical outcome. In the present study we explore whether these signatures also exist in the stroma of ductal carcinoma in situ (DCIS). We studied the signatures by both gene expression profile analysis of a publically available data set of DCIS and by immunohistochemistry (IHC) on a tissue microarray of DCIS and invasive breast cancer cases. Both the gene expression and immunohistochemical data show that the macrophage response and fibroblast expression signatures are present in the stroma of subsets of DCIS cases. The incidence of the stromal signatures in DCIS is similar to the incidence in invasive breast cancer that we have previously reported. We also find that the macrophage response signature is associated with higher grade DCIS and cases which are ER and PR negative, whereas the fibroblast signature was not associated with any clinicopathologic features in DCIS. A comparison of 115 matched cases of DCIS and invasive breast cancer found a correlation between the type of stromal response in DCIS and invasive ductal carcinoma (IDC) within the same patient for both the macrophage response and the fibroblast stromal signatures (P = 0.03 and 0.08, respectively). This study is a first characterization of these signatures in DCIS. These signatures have significant clinicopathologic associations and tend to be conserved as the tumor progresses from DCIS to invasive breast cancer.

Abstract
DCIS is a heterogeneous group of non-invasive cancers of the breast characterized by various degrees of differentiation and unpredictable propensity for transformation into invasive carcinoma. We examined the expression and prognostic value of 9 biological markers with a potential role in tumor progression in 133 patients with pure DCIS treated with breast conserving surgery alone, between 1982–2000. Histology was reviewed and immunohistochemical staining was performed. Pearson correlation coefficient was used to determine the associations between markers and histopathological features. Univariate and multivariate analysis examined associations between time to recurrence and clinico-pathologic features and biological markers. Median age at diagnosis was 55 years (25–85). With a median follow up of 8.91 years, 41/133 patients recurred (21 as invasive recurrence). In this cohort 13.5% had low, 43% intermediate and 42% high nuclear grade. Comedo necrosis was found in 65% of cases. Expression of ER (62.4%), PR (55.6%), HER2/neu (31.6%), MIB1 (39.8%), p53 (22.6%), p21 (39.8%), Cyclin D1 (95.5%) calgranulin (20.5%), psoriasin (12%), was found in DCIS. HER2/neu was overexpressed in 45% that recurred as DCIS and 42.9% that recurred as invasive cancer, and only in 26.1% in cases that never recurred. On univariate analysis, HER2/neu overexpression was the only marker associated with an increased risk for any recurrence (p = 0.044). The hazard ratio for recurrence for HER2/neu positive DCIS was 1.927 (confidence interval 1.016–3.653) compared to HER2 negative DCIS. On multivariate analysis, HER2/neu overexpression remained the only independent variable significantly associated with any recurrence (p = 0.014) and with invasive recurrence (p = 0.044). This data suggest that HER2/neu testing may become an important parameter in the management of DCIS and the treatment of cases with positive HER2/neu status could be modified accordingly, similar to the current approach for HER2/neu positive invasive disease.

Abstract
Certain ductal carcinoma in situ (DCIS) lesions overexpress the HER-2/neu receptor at this early stage of breast cancer development. Recently, we showed that a HER-2-targeted dendritic cell vaccine could be used to eliminate HER-2-overexpressing cells in patients that harbor these high-risk DCIS lesions. Our findings suggest that vaccinating such patients might diminish the risk of recurrence, protect against the development of invasive breast cancer, and minimize morbidity associated with current treatments. We discuss several implications of this work for developing effective cancer vaccines.
