Abstract
Cellular composition and structural organization of cells in the tissue determine effective antitumor response and can predict patient outcome and therapy response. Here we present Seg-SOM, a method for dimensionality reduction of cell morphology in H&E-stained tissue images. Seg-SOM resolves cellular tissue heterogeneity and reveals complex tissue architecture. We leverage a self-organizing map (SOM) artificial neural network to group cells based on morphological features like shape and size. Seg-SOM allows for cell segmentation, systematic classification, and in silico cell labeling. We apply the Seg-SOM to a dataset of breast cancer progression images and find that clustering of SOM classes reveals groups of cells corresponding to fibroblasts, epithelial cells, and lymphocytes. We show that labeling the Lymphocyte SOM class on the breast tissue images accurately estimates lymphocytic infiltration. We further demonstrate how to use Seq-SOM in combination with non-negative matrix factorization to statistically describe the interaction of cell subtypes and use the interaction information as highly interpretable features for a histological classifier. Our work provides a framework for use of SOM in human pathology to resolve cellular composition of complex human tissues. We provide a python implementation and an easy-to-use docker deployment, enabling researchers to effortlessly featurize digitalized H&E-stained tissue.

Abstract
The aim of this study was to find the differences and relationships between normal, atypical ductal hyperplasia (ADH), ductal carcinoma in situ (DCIS), and invasive ductal carcinoma (IDC) lesions of the breast based on biochemical characteristics determined by Raman spectroscopy (RS). After collecting 39 frozen sections from patients who underwent surgical resection or mammotome biopsy, nine normal tissues, seven ADH, eight DCIS, and 15 IDC lesions were detected using confocal RS. We then used leave-one-out cross-validation (LOOCV) and radial basis function (RBF) to build a support vector machine (SVM) diagnosis model. Pronounced mean Raman spectra differences were observed between normal tissues, ADH, DCIS, and IDC tissues. Most noticeable was the increased protein and reduced lipid levels of ADH tissues compared to normal tissues. The major spectra differences in ADH, DCIS, and IDC spectrograms were evidenced by a red shift with a broad peak of CH2 (1301 cm-1), the intensity of the stretching vibration peak of carotenoids (1526 cm-1), a relatively strong band of amide-I (1656 cm-1), and the nuclear (882 cm-1) acid peak. Atypical ductal hyperplasia tissues had the largest constituent variations between subjects. During the disease progression, IDC tissues have smaller inter-subject constituent variations than DCIS and ADH tissues. The overall accuracy of SVM model is 74.39%. The sensitivities of normal tissue, ADH, DCIS, and IDC are 62.5%, 50%, 90%, and 66.7%, respectively. The specificities of normal tissue, ADH, DCIS, and IDC are 100%, 100%, 66.7%, and 89.06%, respectively. Atypical ductal hyperplasia shows significant differences and the relationship between normal tissue and malignant disease. Further study to explain the biochemical relationships between these differences will shed more light into a better understanding of the mechanism by which ADH converts to DCIS and to IDC.

Abstract
INTRODUCTION Ductal carcinoma in situ (DCIS) usually manifests as microcalcification on mammography but may be uncalcified. Consequently, a quarter of patients undergoing excision of a presumed pure DCIS require further surgery to re-excise margins. Patients at highest risk of margin involvement may benefit from additional preoperative assessment. METHODS A retrospective review was carried out of patients treated for screen detected, biopsy proven DCIS in a single centre over a ten-year period (1999-2009). Logistic regression analysis identified factors predictive of need for further surgery to clear margins. RESULTS Overall, 248 patients underwent surgery for DCIS (low/intermediate grade: 82, high grade: 155) and 49 (19.8%) required further surgery. High grade disease was associated with greater mammographic extent (mean: 32mm [range: 5-120mm] vs 25mm [range: 2-100mm]), p=0.009) and higher incidence of mastectomy (38% vs 24%, p=0.034). Factors predictive of involvement of surgical margins necessitating further surgery included negative oestrogen receptor status (OR: 5.2, 95% CI: 2.1-12.8, p<0.001) and mammographic extent (odds ratio [OR]: 1.6, 95% confidence interval [CI]: 1.2-2.1, p=0.004). Once size exceeded 30mm, more than 50% of patients required secondary breast surgery for margins. CONCLUSIONS Reoperation rates for DCIS increase with preoperative size on mammography and negative oestrogen receptor status on core biopsy. Patients with these risk features should be counselled accordingly and consideration should be given to the role of additional preoperative imaging.

Abstract
OBJECTIVE There have been calls to remove 'carcinoma' from terminology for in situ cancers such as ductal carcinoma in situ (DCIS), to reduce overdiagnosis and overtreatment. We investigated the effect of describing DCIS as 'abnormal cells' versus 'pre-invasive breast cancer cells' on women's concern and treatment preferences. SETTING AND PARTICIPANTS Community sample of Australian women (n=269) who spoke English as their main language at home. DESIGN Randomised comparison within a community survey. Women considered a hypothetical scenario involving a diagnosis of DCIS described as either 'abnormal cells' (arm A) or 'pre-invasive breast cancer cells' (arm B). Within each arm, the initial description was followed by the alternative term and outcomes reassessed. RESULTS Women in both arms indicated high concern, but still indicated strong initial preferences for watchful waiting (64%). There were no differences in initial concern or preferences by trial arm. However, more women in arm A ('abnormal cells' first term) indicated they would feel more concerned if given the alternative term ('pre-invasive breast cancer cells') compared to women in arm B who received the terms in the opposite order (67% arm A vs 52% arm B would feel more concerned, p=0.001). More women in arm A also changed their preference towards treatment when the terminology was switched from 'abnormal cells' to 'pre-invasive breast cancer cells' compared to arm B. In arm A, 18% of women changed their preference to treatment while only 6% changed to watchful waiting (p=0.008). In contrast, there were no significant changes in treatment preference in arm B when the terminology was switched (9% vs 8% changed their stated preference). CONCLUSIONS In a hypothetical scenario, interest in watchful waiting for DCIS was high, and changing terminology impacted women's concern and treatment preferences. Removal of the cancer term from DCIS may assist in efforts towards reducing overtreatment.

Abstract
PURPOSE To assess the clinical value of second-look ultrasound (US) examination for the evaluation of additional enhancing lesions detected on magnetic resonance (MR) imaging. MATERIALS AND METHODS Between May 2008 and February 2011, 794 consecutive patients with histologically confirmed breast cancer underwent breast MR imaging. We included 101 patients with 132 additional enhancing breast lesions detected on MR imaging who underwent second-look US. The imaging features and lesion category according to the Breast Imaging and Reporting and Data System (BI-RADS) were assessed with MR and US imaging, respectively. RESULTS According to the BI-RADS system, 67 lesions (50.8 %) were classified as category 0, 33 lesions (25.0 %) as category 3, and 32 lesions (24.2 %) as category 4. Of the 67 indeterminate lesions on MR imaging, 34 (50.7 %) were demonstrated on second-look US. 11 of these 34 lesions showed suspicious sonographic features, including 1 lesion that showed malignancy (9.1 %, 1/11). Most of the suspicious lesions on MR imaging (26 of 32 BI-RADS category 4 lesions, 81.3 %) were demonstrated on second-look US, and 17 were malignant (65.4 %, 17/26). Of the 6 BI-RADS category 4 lesions without sonographic correlation, 1 was malignant (16.7 %, 1/6). CONCLUSION Second-look US examination was useful for evaluating MR-detected lesions in patients with breast cancer.

Abstract
Aims Radiation Therapy Oncology Group 98-04 sought to identify women with ‘good risk’ ductal carcinoma in situ (DCIS) who receive no significant benefit from radiation. Enrolment criteria excluded close or positive margins and grade 3 disease. To ensure reproducibility in identifying good risk pathology, an optional web based teaching tool was developed and a random sampling of 10% of submitted slides were reviewed by a central pathologist. Methods Submitting pathologists were asked to use the web based teaching tool and submit an assessment of the tool along with the pathology specimen form and DCIS H&E stained slide. Per protocol pathology was centrally reviewed for 10% of the cases. Results Of the 55 DCIS cases reviewed, three had close or positive margins and three were assessed to include grade 3 DCIS, therefore 95% of DCIS cases reviewed were correctly graded, and 89% reviewed were pathologically appropriate for enrolment. Regarding the teaching tool, 13% of DCIS cases included forms that indicated the website was used. One of these seven who used the website submitted DCIS of grade 3. Conclusions Central review demonstrates high pathological concordance with enrolment eligibility, particularly with regard to accurate grading. The teaching tool appeared to be underused.

Abstract
BACKGROUND Breast carcinoma in situ (CIS) is classified into ductal carcinoma in situ (DCIS) and lobular carcinoma in situ (LCIS). DCIS is treated with surgical excision while LCIS can be clinically followed with or without hormonal treatment. Thus, it is critical to distinguish DCIS from LCIS. Immunohistochemical (IHC) staining for E-cadherin is routinely used to differentiate DCIS from LCIS in diagnostically challenging cases. Circumferential diffuse membranous staining of E-cadherin is the typical pattern in DCIS, whereas LCIS lacks or shows decreased E-cadherin expression. Recent studies have shown that DCIS has membranous staining of P120 catenin and LCIS has diffuse cytoplasmic staining of P120 catenin. We developed a cocktail composed of E-cadherin and P120 catenin primary antibodies so that only one slide is needed for the double immunostains. DESIGNS Twenty-seven blocks of formalin-fixed paraffin-embedded tissue from 26 cases of DCIS or LCIS were retrieved from the archives of Houston Methodist Hospital. Four consecutive sections from the same blocks were used for H&E and immunohistochemical (IHC) stains. The E-cadherin antibody was a rabbit polyclonal antibody and the P120 catenin antibody was a mouse monoclonal antibody. The E-cadherin primary antibody was detected using a secondary antibody raised against rabbit antibody and was visualized with a brown color. The P120 catenin primary antibody was detected using a secondary antibody raised against mouse antibody and was visualized with a red color. RESULTS Using individual antibodies, 15 of 15 DCIS lesions had diffuse circumferential membranous E-cadherin staining (brown stain) or P120 catenin staining (red stain). All 12 LCIS cases showed cytoplasmic P120 red staining or loss of E-cadherin staining when the single P120 catenin or E-cadherin antibody was used. When stained with the antibody cocktail, all 15 DCIS samples showed diffuse red and brown membranous staining without cytoplasmic stain; all 12 LCIS samples showed diffuse cytoplasmic red staining for P120 catenin but no membranous staining for E-cadherin. CONCLUSIONS 1. This antibody cocktail can be applied in daily practice on paraffin-embedded tissue and is especially useful in small biopsies with small foci of CIS lesions. 2. Immunohistochemical staining with the antibody cocktail showed 100% concordance with the traditional single antibody immunostaining using either E-cadherin or P120 catenin antibody. 3. Our antibody cocktail includes E-cadherin as a positive membranous stain for DCIS and P120 catenin as a positive cytoplasmic stain for LCIS, which may enhance accuracy and confidence in the differential diagnoses.

Abstract
OBJECTIVE To determine the frequency of the immunohistochemical profiles of a series of high-grade ductal carcinoma in situ of the breast. METHODS One hundred and twenty-one cases of high-grade ductal carcinoma in situ, pure or associated with invasive mammary carcinoma, were identified from 2003 to 2008 and examined with immunohistochemistry for estrogen receptor, human epidermal growth factor receptor 2, cytokeratin 5, and epidermal growth factor receptor. The tumors were placed into five subgroups: luminal A, luminal B, HER2, basal-like, and "not classified". RESULTS The frequencies of the immunophenotypes of pure ductal carcinoma in situ were the following: luminal A (24/42 cases; 57.1%), luminal B (05/42 cases; 11.9%), HER2 (07/42 cases; 16.7%), basal-like phenotype (00/42 cases; 0%), and "not classified" (06/42 cases; 14.3%). The immunophenotypes of ductal carcinoma in situ associated with invasive carcinoma were the following: luminal A (46/79 cases; 58.2%), luminal B (10/79 cases; 12.7%), HER2 (06/79 cases; 7.6%), basal-like (06/79 cases; 7.6%), and "not classified" (11/79 cases; 13.9%). There was no significant difference in the immunophenotype frequencies between pure ductal carcinoma in situ and ductal carcinoma in situ associated with invasive carcinoma (p>0.05). High agreement was observed in immunophenotypes between both components (kappa=0.867). CONCLUSION The most common immunophenotype of pure ductal carcinoma in situ was luminal A, followed by HER2. The basal-like phenotype was observed only in ductal carcinoma in situ associated with invasive carcinoma, which had a similar phenotype.

Abstract
PURPOSE To describe the sonoelastographic appearance of breast cysts (simple, complicated-cysts with sedimentation and complex-cysts with internal solid parts). To assess the influence of sonoelastography on the BI-RADS classification of complicated cysts. MATERIALS AND METHODS A prospective study was conducted and all cysts diagnosed by the same radiologist between May 2007 and July 2008 in our breast unit were included. Each lesion was assessed according to BI-RADS and the Tsukuba elasticity score using a Hitachi 8500 US device. Cytology or histopathology was obtained for complicated and complex cysts. RESULTS 49 simple, 43 complicated and 14 complex cysts were detected. The elasticity patterns were divided into 4 categories: typical BGR (blue-green-red) pattern, appearance similar to that described for solid. lesions, variants of BGR, an inverse score of 3. The BGR pattern was predominant in breast cysts. Atypical elasticity patterns were mostly associated with complicated and complex cysts. BI-RADS classification of complicated cysts before and after elastography showed a statistically significant difference in terms of final category assessment (most of the complicated cysts were downgraded to BI-RADS 2 after elastography). CONCLUSION Being aware of the wide spectrum of elastographic patterns of breast cysts and considering elastography when assessing the BI-RADS category of complicated cysts may lead radiologists to better patient management.

Abstract
INTRODUCTION Male breast cancer (MBC) is a rare and inadequately characterized disease. The aim of the present study was to characterize MBC tumors transcriptionally, to classify them into comprehensive subgroups, and to compare them with female breast cancer (FBC). METHODS A total of 66 clinicopathologically well-annotated fresh frozen MBC tumors were analyzed using Illumina Human HT-12 bead arrays, and a tissue microarray with 220 MBC tumors was constructed for validation using immunohistochemistry. Two external gene expression datasets were used for comparison purposes: 37 MBCs and 359 FBCs. RESULTS Using an unsupervised approach, we classified the MBC tumors into two subgroups, luminal M1 and luminal M2, respectively, with differences in tumor biological features and outcome, and which differed from the intrinsic subgroups described in FBC. The two subgroups were recapitulated in the external MBC dataset. Luminal M2 tumors were characterized by high expression of immune response genes and genes associated with estrogen receptor (ER) signaling. Luminal M1 tumors, on the other hand, despite being ER positive by immunohistochemistry showed a lower correlation to genes associated with ER signaling and displayed a more aggressive phenotype and worse prognosis. Validation of two of the most differentially expressed genes, class 1 human leukocyte antigen (HLA) and the metabolizing gene N-acetyltransferase-1 (NAT1), respectively, revealed significantly better survival associated with high expression of both markers (HLA, hazard ratio (HR) 3.6, P = 0.002; NAT1, HR 2.5, P = 0.033). Importantly, NAT1 remained significant in a multivariate analysis (HR 2.8, P = 0.040) and may thus be a novel prognostic marker in MBC. CONCLUSIONS We have detected two unique and stable subgroups of MBC with differences in tumor biological features and outcome. They differ from the widely acknowledged intrinsic subgroups of FBC. As such, they may constitute two novel subgroups of breast cancer, occurring exclusively in men, and which may consequently require novel treatment approaches. Finally, we identified NAT1 as a possible prognostic biomarker for MBC, as suggested by NAT1 positivity corresponding to better outcome.

Abstract
PURPOSE The purpose of this retrospective study was to calculate the positive predictive value (PPV) of sonographic Breast Imaging Reporting and Data System (BI-RADS) categories 3, 4, and 5 in different age groups to investigate whether age influences the PPV of the BI-RADS category in breast ultrasound. MATERIALS AND METHODS From our sonography-guided core biopsy database of breasts between 2006 and 2008, we identified 2817 BI-RADS category 3, 4, and 5 lesions with known pathological diagnosis in 2587 women, all of whom underwent the earlier breast assessment via ultrasound with a sonographic BI-RADS lexicon and later sonography-guided core biopsy. All lesions were classified into three age groups (< 45, 45 - 59, and > 59 years). The age-related PPVs of each BI-RADS category among three age groups were calculated on the basis of pathological diagnoses and were compared using a χ(2)-test. RESULTS The overall PPV of each BI-RADS category was 2.2 % in category 3, 6.5 % in category 4a, 35.2 % in category 4b, 79.6 % in category 4c, and 99.6 % in category 5. The age-related PPVs of category 3 varied significantly among the three age groups (0.9 % versus 3.9 % versus 2.0 % p = 0.048), and notably, the age-related PPV in group 2 was higher than the others. Additionally, there was a significant positive association between the age-related PPVs and increasing age in categories 4a and 4b (4a, p < 0.0001 and 4b, p = 0.0139), but not in categories 4c and 5 (4c, p = 0.1853 and 5, p = 0.2871). CONCLUSION The incidence of female breast cancer differs not only in different sonographic BI-RADS categories, but also in different age groups. Therefore, more attention should be paid to the special age group that we found for sonographic BI-RADS categories 3, 4a, and 4b.

Abstract
BACKGROUND Studies have shown that breast infiltrating ductal carcinoma develops from precursor lesions or pre-invasive. It is accepted that the risk of invasive ductal carcinoma increased slightly in hyperplasia, but especially in cases of atypical hyperplasia and intraductal carcinoma. OBJECTIVES To evaluate and compare the nodal status between ductal breast cancer with in situ component (group 1) or without it (group 2). MATERIAL AND METHOD Descriptive and retrospective study that included 454 ductal breast cancers. Data concerning clinical and pathological variables was collected. All data was compared between both groups. RESULTS Among all cases, 176 (38.8%) showed positive lymph nodes, 136 patients (39.5%) from group 1 and 40 cases (36.4%) from group 2. Among group 1 cases, high-grade subgroup showed higher positive lymph node rate (82 cases, 55.4%) than the extensive in situ carcinomas subgroup (84 cases, 49.7%). Both of them had a significant higher rate than group 2 cases (p = 0.003 y p = 0.028, respectively). Moreover, the low-grade in situ carcinomas without cellular necrosi had positive lymph nodes just in 30 cases (24%), significantly lower (p = 0.034) than group 2. CONCLUSIONS We did not find overall statistical differences between groups depending on in situ associated component. But when we analyzed in situ subgroups, we found differences with higher positive lymph node rate in high grade carcinomas and extensive in situ carcinomas subgroups, while lower affectation rates were observed in low grade carcinomas (without cellular necrosis), compared to the group of breast cancers without in situ component associated.

Abstract
PURPOSE Hitachi real-time tissue elastography (HI-RTE) is an ultrasound technique that facilitates the estimation of tissue elasticity. Our study evaluates whether sonoelastography improves the differentiation of benign and malignant breast lesions. MATERIALS AND METHODS In a multicenter approach sonoelastography of focal breast lesions was carried out in 779 patients with subsequent histological confirmation. We present data from 3 study centers (Berlin, Bielefeld, Homburg/Saar) focusing on the sensitivity (SE), specificity (SP) and the positive (PPV) and negative predictive value (NPV) of sonoelastography. In addition we performed an analysis of the diagnostic performance, expressed by the pretest and posttest probability of disease (POD), in BI-RADS®-US 3 or 4 lesions as these categories can imply both malignant and benign lesions and a more precise prediction would be a preferable aim. RESULTS Sonoelastography demonstrated an improved SP (89.5 %) and an excellent PPV (86.8 %) compared to B-mode ultrasound (76.1 % and 77.2 %). Especially in dense breasts ACR III-IV, the SP was even higher (92.8 %). In BI-RADS-US 3 lesions, a suspicious elastogram significantly modified the POD from 8.3 % to a posttest POD of 45.5 %. In BI-RADS-US 4 lesions, we found a pretest POD of 56.6 %. The posttest POD changed significantly to 24.2 % with a normal elastogram and to 81.5 % with a suspicious elastogram. CONCLUSION Our data demonstrates that the complementary use of sonoelastography definitely improves the performance in breast diagnostics. Finally we present a protocol of how sonoelastography can be integrated into our daily practice.

Abstract
BACKGROUND Ductal intraepitelial neoplasia (DIN) represents a spectrum of disease that may progress from usual hyperplasia to ductal carcinoma in situ (DCIS) grade 3. The aim of the study was to asses the correlation between the DIN classification and the surgical treatment including sentinel lymph node biopsy (SLNB). PATIENTS AND METHODS In this retrospective study, 229 patients with DIN had undergone conservative or radical surgical treatment and SLNB in cases of DIN1C-DIN3. RESULTS Breast conservative surgery was the definitive treatment in 80% of the cases. The H&E evaluation of excised sentinel nodes was negative for metastatic disease; nevertheless the immunohistochemical (IHC) evaluation revealed the presence of metastatic cells in 6 patients (3.7%). CONCLUSION In cases of DIN lesions SLNB is not indicated. The only reason SLNB should be considered is when there is an evidence of invasive foci at definitive histology or when radical mastectomy is proposed.

Abstract
BACKGROUND Stereotactic breast biopsy using the Mammotome system allows minimal invasive tissue sampling of suspicious lesions of the breast cancer, e.g. clustered microcalcifications BI-RADS type 3 and 4, and has widely replaced open surgical biopsies. The aim of this retrospective study was to review the results of these biopsies in regard of technical feasibility and complications as well as to correlate initial BI-RADS assessment with histopathology. METHODS One hundred thirty-five vacuum-assisted breast biopsies in 124 patients were evaluated. Before biopsy, the mammograms were classified according to the Breast Imaging Reporting and Data System (BI-RADS). All mammograms were reviewed with knowledge of the final histologic diagnosis. Patients with benign diagnoses underwent mammographic follow-up. Excisional biopsy was recommended for diagnoses of in-situ or invasive carcinoma. RESULTS No serious complications of the biopsies were observed. Histopathology revealed 105 (78%) benign lesions. Benign lesions were classified as BI-RADS 3 in 49 (36%) and as suspicious (BI-RADS 4) in 56 (41%). Thirty lesions (22%) were malignant, of which 26 (87%) were classified BI-RADS 4 or 5. The frequency of malignancy in BI-RADS 4 and 5 was 19 of 75 (25%) and 7 of 7 (100%), respectively. Of the 53 BI-RADS 3 lesions, 4 (8%) were malignant. CONCLUSIONS Mammotome biopsy was shown to be a safe and well-tolerated technique for the work-up of mammographic lesions. The frequency of malignant histopathologic findings in BI-RADS 3 lesions was higher than expected, reflecting the difficulties in the mammographic differentiation of benign and malignant clustered microcalcifications.

Abstract
AIMS There is considerable evidence to link cyclooxygenase (COX)-2 to the development of cancer. The aim of this study was to assess COX-2 expression and its subcellular localization in lobular in situ neoplasia (LIN) of the breast and to verify differences in COX-2 expression between different grades of lesions according to the Tavassoli classification. METHODS AND RESULTS We analysed the expression of COX-2 protein by immunohistochemistry in tissue samples of 51 LIN lesions classified into three grades according to the Tavassoli classification. COX-2 immunostaining was observed in 78.4% of LIN samples and showed a prevalent membranous rather than cytoplasmic pattern. COX-2 was expressed in 16/17 (94.1%) LIN1, 22/25 (88%) LIN2 and 2/9 (22.2%) LIN3. As regards COX-2 expression, a statistically significant difference was found between LIN1 and LIN3 (P = 0.001) and between LIN2 and LIN3 (P =0.001). No difference was found between LIN1 and LIN2. Moreover, a significant negative correlation was found between LIN grade and COX-2 expression (P < 0.0001). CONCLUSIONS COX-2 is highly expressed in LIN, supporting a role for this protein in the early stage of breast carcinogenesis, representing the rationale for using COX-2 selective inhibitors in the earliest stages of breast cancer.

Abstract
The purpose of the present paper was to evaluate the clinicopathological and biological features of 20 Japanese patients with solid-papillary carcinoma of the breast (SPC) or SPC associated with invasive breast cancer. All the patients were Japanese women, including two sisters. The mean age was 66.0 years. The incidence of SPC among all the breast cancers treated at two institutions was 1.1% and 1.7%, respectively. The mean disease-free interval was 4 years 11 months. Axillary lymph node metastasis or tumor recurrence did not occur in any of the cases. Fifteen cases of SPC contained invasive cancers that ranged from <5% to 60% of the entire tumor area. Histological types of invasive cancers were mucinous carcinoma in five cases and neuroendocrine cell carcinoma in 10 cases. These results indicate that SPC is a potential precursor lesion for neuroendocrine carcinoma as well as mucinous carcinoma. When all the cases were classified and analyzed according to both the 2002 tumor node metastasis (TNM) classification system and the Nottingham histological grade, SPC patients, even those with invasive cancers, seemed to have longer disease-free survival compared to patients with the other invasive breast cancers of matching grade and stage. Clinicopathologically, SPC could be regarded as a separate type of ductal carcinoma in situ.

Abstract
Microarray profiling of invasive breast carcinomas has identified subtypes including luminal A, luminal B, HER2-overexpressing, and basal-like. The poor-prognosis, basal-like tumors have been immunohistochemically characterized as estrogen receptor (ER)-negative, HER2/neu-negative, and cytokeratin 5/6-positive and/or epidermal growth factor receptor (EGFR)-positive. The aim of this study was to determine the prevalence of basal-like ductal carcinoma in situ in a population-based series of cases using immunohistochemical surrogates. A total of 245 pure ductal carcinoma in situ cases from a population-based, case-control study were evaluated for histologic characteristics and immunostained for ER, HER2/neu, EGFR, cytokeratin 5/6, p53, and Ki-67. The subtypes were defined as: luminal A (ER+, HER2-), luminal B (ER+, HER2+), HER2 positive (ER-, HER2+), and basal-like (ER-, HER2-, EGFR+, and/or cytokeratin 5/6+). The prevalence of breast cancer subtypes was basal-like (n = 19 [8%]); luminal A, n = 149 (61%); luminal B, n = 23 (9%); and HER2+/ER-, n = 38 (16%). Sixteen tumors (6%) were unclassified (negative for all 4 defining markers). The basal-like subtype was associated with unfavorable prognostic variables including high-grade nuclei (P < .0001), p53 overexpression (P < .0001), and elevated Ki-67 index (P < .0001). These studies demonstrate the presence of a basal-like in situ carcinoma, a potential precursor lesion to invasive basal-like carcinoma.

Abstract
INTRODUCTION Ductal carcinoma in situ (DCIS) is characterised by the intraductal proliferation of malignant epithelial cells. Several histological classification systems have been developed, but assessing the histological type/grade of DCIS lesions is still challenging, making treatment decisions based on these features difficult. To obtain insight in the molecular basis of the development of different types of DCIS and its progression to invasive breast cancer, we have studied differences in gene expression between different types of DCIS and between DCIS and invasive breast carcinomas. METHODS Gene expression profiling using microarray analysis has been performed on 40 in situ and 40 invasive breast cancer cases. RESULTS DCIS cases were classified as well- (n = 6), intermediately (n = 18), and poorly (n = 14) differentiated type. Of the 40 invasive breast cancer samples, five samples were grade I, 11 samples were grade II, and 24 samples were grade III. Using two-dimensional hierarchical clustering, the basal-like type, ERB-B2 type, and the luminal-type tumours originally described for invasive breast cancer could also be identified in DCIS. CONCLUSION Using supervised classification, we identified a gene expression classifier of 35 genes, which differed between DCIS and invasive breast cancer; a classifier of 43 genes could be identified separating between well- and poorly differentiated DCIS samples.

Abstract
The intraductal papillary-mucinous neoplasms of the pancreas have only recently been recognized as a clinical and pathological entity. They show an adenoma-carcinoma sequence, but have a much more favorable prognosis than ductal adenocarcinoma. Moreover, it has become clear that they constitute a heterogeneous group with at least four histopathological subtypes that have different biological properties with different prognostic implications.

Abstract
Studying the molecular stratification of breast carcinoma is a real challenge considering the extreme heterogeneity of these tumors. Many patients are now treated following recommendation established at several NIH and St Gallen consensus conferences. However a significant fraction of these breast cancer patients do not need adjuvant chemotherapies while other patients receive inefficacious therapies. High density gene expression arrays have been designed to attempt to establish expression profiles that could be used as prognostic indicators or as predictive markers for response to treatment. This review is intended to discuss the potential value of these new indicators, but also the current weaknesses of these new genomic and bioinformatic approaches. The combined analysis of transcriptomic and genomic alteration data from relatively large numbers of well annotated tumor specimens may offer an opportunity to overcome the current difficulties in validating recently published non overlapping gene lists as prognostic or therapeutic indicators. There is also hope for identifying and deciphering signal transduction pathways driving tumor progression with newly developed algorithms and semi quantitative parameters obtained in simplified in vitro or in vivo models for specific transduction pathways.

Abstract
The proto-oncogene c-KIT (CD117) is highly expressed in normal breast epithelium and is decreased in invasive breast cancer. In this study, we analyzed the protein expression and the mutational status of c-KIT in ductal carcinoma in situ (DCIS) of the breast and correlated these findings with nuclear grade, architectural pattern, and expression of HER-2, estrogen receptor (ER)-alpha, and progesterone receptor (PR). C-KIT, HER-2, ER, and PR expression were analyzed immunohistochemically in 106 cases of paraffin-embedded DCIS (85 pure DCIS and 21 DCIS with concurrent carcinoma). Direct sequencing of exons 9 and 11 of the c-KIT gene was performed to analyze the hot spot mutational regions in representative cases. C-KIT expression was found in 55 (52.8%) of all DCIS, correlating with high nuclear grade (P < .0001), comedonecrosis (P < .0001), and solid growth pattern (P = .001). Furthermore, c-KIT expression was strongly associated with HER-2 positivity (P < .0001) and was significantly lower in ER- or PR-positive cases (P = .001 and P = .006, respectively). C-KIT expression alone or co-expression with HER-2 in pure DCIS did not differ significantly from DCIS with invasive component (P = .09). Mutational analysis in 6 c-KIT-positive DCIS revealed no activating mutations in exons 9 or 11. Our findings suggest that the expression of c-KIT protein might define a subset of poorly differentiated, HER-2-positive DCIS with decreased expression of steroid hormone receptors, comedonecrosis, and a solid growth pattern. The implications of c-KIT and HER-2 co-expression for breast carcinogenesis should be further evaluated.

Abstract
Ductal intra-epithelial lesions of the breast are associated with invasive neoplasms and comprise a large spectrum of histological patterns. We have examined 23 cases of pure tubular carcinomas (TCs) of the breast and 53 cases of invasive ductal low-grade carcinomas to determine the relationship and distribution of intra-epithelial lesions, mainly of ductal in situ carcinoma type, but including also lobular intra-epithelial neoplasia (LIN) in both entities. Eleven cases of TC showed flat epithelial atypia (FEA) (47.8%), and, in 14 and 6 cases, micropapillary and cribriform low-grade ductal carcinoma in situ (DCIS) were present (60.7 and 26.1%, respectively). On the opposite, in ductal grade I invasive carcinomas, the most frequent architectural pattern was low-grade DCIS growing in arcades in 26 cases (49%). While absent in TCs, low-grade DCIS of solid type was found in five (9.4%) cases of ductal invasive carcinomas, where FEA were present in seven (13.2%) cases. LIN lesions were present in four (17.4%) cases of TC, whereas they represented 7.5%, as reported by Carstens et al. (Am J Clin Pathol 58:231-238, 1972), of cases of low-grade carcinomas. These results suggest that invasive pure TC and low-grade ductal carcinomas of the breast are different lesions, and support the fact that TC, of low histopathological grade, is a particular distinct tumoural entity.

Abstract
RATIONALE AND OBJECTIVES Near-infrared (NIR) technology appears promising as a noninvasive technique for breast cancer screening and diagnosis. The technology capitalizes on the relative transparency of human tissue in this spectral range and its sensitivity to the main components of the breast: water, lipid, and hemoglobin. In this study, the authors report quantitative measurements of these components and the functional contrast between healthy and diseased tissue. MATERIALS AND METHODS A four-wavelength time domain optical imaging system was used to perform noninvasive NIR measurements in the breast of 49 women both pre- and postmenopausal, ages 24-80. Algorithms based on a diffusive model of light transport provided absolute bulk and local values of breast constituent concentrations. RESULTS Important variations in the functional and structural NIR properties of the breast were observed. Demographics trend were noticed in accordance with breast physiology. In the 23 cases imaged with suspicious masses, the optical images were consistent with the mammographic findings. Substantial contrast between masses and adjacent tissue is observed. Moreover, consistent differences between malign and benign cases are found with optical imaging. CONCLUSION The results of this pilot study illustrate the sensitivity of optical techniques to the composition of the breast. In addition, preliminary data suggest that benign and malignant tumors can potentially be noninvasively differentiated with optical imaging. Moreover, statistically significant discrimination based on deoxy-hemoglobin content between malign and benign cases was found with optical imaging (P = .0184, one-tailed t test).

Abstract
We postulate that ductal carcinoma in situ (DCIS), and consequently breast carcinoma in general, is a lobar disease, as the simultaneously or asynchronously appearing, often multiple, in situ tumor foci are localized within a single lobe. Although the whole lobe is sick, carrying some form of genetic instability, the malignant transformation of the epithelial cells may appear localized to a part or different parts of the sick lobe at the same time or with varying time difference. It may be confined to terminal ductal lobular units (TDLUs), to ducts or both. The malignant transformation is often associated with aberrant branching and/or aberrant lobularization within the sick lobe. Involvement of a single individual TDLU or of a group of adjacent TDLUs generates a unifocal lesion. Multifocal lesions appear if distant TDLUs are involved. Diffuse growth pattern in DCIS indicates involvement of the larger ducts. The extent of the involved area in multifocal or diffuse cases varies considerably. Diffuse growth pattern with or without evidence of aberrant arborisation within the sick lobe seems to characterize a subgroup of DCIS with unfavourable prognosis. In this paper, we discuss the anatomical, embryological and pathological background of the theory of the sick lobe and present supporting evidence from modern radiological breast imaging, long-term follow-up studies and from our own series of 108 DCIS cases.

Abstract
AIMS The incidence of ductal carcinoma in situ (DCIS) has increased substantially since the advent of widespread screening mammography. Identification of histological markers that predict recurrent disease is essential for optimal treatment management. To assist the clinico-pathological stratification of DCIS, we sought to determine histological markers of recurrence in DCIS in an Australian population-based series. METHODS In a study of all DCIS reported in Victoria between 1988 and 1992, managed by breast conserving therapy (wide local excision or subtotal mastectomy) with or without adjuvant radiotherapy and/or hormonal therapy, the histological features of DCIS lesions with subsequent ipsilateral recurrence as in situ or invasive breast cancer were compared with a similarly managed control group of DCIS without recurrence. RESULTS Large lesion size, presence of nuclear pleomorphism, absence of cellular polarisation and extensive necrosis were all significant predictors of recurrence (P<0.05). Primary and recurrent DCIS lesions had similar morphological features, and invasive recurrence was characterised by ductal type with high nuclear grade. CONCLUSION This study identifies histological markers in DCIS associated with recurrence in an Australian population, and demonstrates similar histological appearances between primary and secondary lesions. These histological characteristics may be used to stratify DCIS subtypes and facilitate the future optimisation of disease management.

Abstract
Ductal intraepithelial neoplasia (DIN) is descriptive of in situ breast lesions from usual ductal hyperplasia (UDH) to advanced ductal carcinoma in situ (DCIS). A total of 2628 cases of DIN diagnosed at the Armed Forces Institute of Pathology were separated based on their grade. These were assessed for the presence of invasive carcinoma (ductal or lobular) and lobular intraepithelial neoplasia (LIN) grades 1-3. The frequency of invasive cancer (ductal and lobular) appearing with DIN increased with increasing DIN grade from 2% in low-risk DIN (UDH) to 37% in DIN 2-3 (DCIS grades 2-3). The frequency of these invasive carcinomas, which were either lobular or displayed lobular features, however, decreased with increasing grade of DIN with a peak of 28% in DIN 1-flat type, (flat epithelial atypia) to a low of 2% in DIN 3. Likewise, the frequency of LIN appearing with DIN decreased as the grade of DIN increased, with a peak of 26% in DIN 1-flat type to a low of 9% in DIN 3. Lower-grade LIN 1 comprised 14% of the LIN in low-risk DIN cases, but only 4% of the LIN seen in DIN 3 cases. Conversely, higher-grade LIN 3 comprised only 6% of the LIN seen in low-risk DIN cases, while accounting for 15% of the LIN in DIN 3 cases. The frequency of invasive carcinoma in DIN 1 ranged from 4% in quantitatively limited DIN 1 less than or equal to 2 mm (atypical ductal hyperplasia) to 27% among the more abundant DIN 1 greater than 2 mm (DCIS grade 1). The frequency of LIN associated with DIN 1 less than or equal to 2 mm was 13.4%, and the frequency of LIN associated with DIN 1 greater than 2 mm was 16.6% when there was no DIN 1-flat type present. However, the frequency of the LIN seen in combination with DIN 1-flat type was reduced by 50% as the quantity of DIN exceeded 2 mm. Based on this retrospective analysis of DIN, we noted that: (1) invasive carcinoma is most frequently associated with the higher grades of DIN; (2) the grade of LIN parallels the grade of coexisting DIN; (3) a relationship exists between DIN 1-flat type and the occurrence of LIN and (4) this relationship in association with DIN less than or equal to 2 mm is not maintained in DIN greater than 2 mm.

Abstract
"Columnar cell lesions" is a general descriptive term referring to disparate lesions having in common cells with a columnar configuration but not necessarily identical histologic or biologic characteristics. Within this large category, a group of lesions having in common a population of atypical cells (frequently columnar shaped) is emerging as early neoplastic lesions. This article reviews the histological features, differential diagnosis, associated lesions, biologic potential, clinical significance, and management of atypical columnar cell lesions.

Abstract
Although most cases of carcinoma in-situ are easily classified as either ductal or lobular on the basis of their pattern of involvement and the nature of their cell-to-cell relation, a few pose diagnostic problems. Attention to the presence of associated lesions and the results of immunohistochemical staining for E-cadherin and, to a lesser extent, cytokeratin can help to categorize problematic cases. This article reviews the histological criteria employed to separate ductal carcinoma in situ from lobular carcinoma in situ, the role of immunohistochemistry in the diagnosis of equivocal lesions, and the evidence suggesting the existence of combined and truly hybrid forms.

Abstract
Local recurrence after lumpectomy for ductal carcinoma in situ (DCIS) is a major concern and is related to residual disease in the breast. We studied the predictive value of lumpectomy margins for residual DCIS and compared our results and pathological processing techniques with those published in the literature. Margin status was determined for 89 patients with screen-detected DCIS who had lumpectomy and re-excision, for the presence and extent of residual disease. Margin width was defined as the narrowest distance between tumor and any inked margin or, where margins were positive, classified into focal involvement (<1 mm of the inked surface involved), minimal (>or=1<15 mm) and extensive (>or=15 mm). The amount of residual tumor was quantified according to the number of ducts involved with tumor: small (fewer than 10 ducts) or large (10 or more ducts) residuum. The initial margin status was a significant predictor for the presence of residual tumor in re-excision specimens (P=0.006). There was residual tumor in 44 and 45% of close non-involved (>1 and <or=1 mm width) margins, 67% of focally, 71% of moderately and 94% of extensively positive margins. The pathologic tumor size was also a predictor for the presence of residual tumor with 27, 68 and 74% of lesions measuring <or=10, 11-25, >25 mm,respectively, showing residual disease. The presence of residual tumor was not significantly related to age, mammographic appearance, nuclear grade or intraductal necrosis. The initial margin status was found to predict for the amount of residual tumor. With careful margin assessment, margin status after lumpectomy for DCIS can be used to predict for the presence and amount of residual tumor in the breast and is a guide to further management decisions. A standard for margin status reporting and pathological processing of screen-detected DCIS in situ lesions will help in the interpretation of data from different institutions.

Abstract
As a consequence of increased screening mammography, ductal carcinoma in situ represents a growing percentage of breast cancer diagnoses. The management of per-cutaneous biopsies as well as wire-localized surgical biopsies is a difficult task for pathologists. In this Article, we describe the diagnostic criteria of these lesions as well as the histopathological characteristics of their two principal differential diagnoses: atypical ductal hyperplasia and micro-infiltrating carcinoma. We also detail the utility of immunohistochemistry in the diagnosis of these lesions. This paper reviews the accepted prognostic factors for ductal carcinoma in situ and describes the important techniques needed to characterize them (grade and extent, status of margins and exclusion of microinvasion). Correct handling of pathological specimens, as detailed here, is one of the main keys for therapeutic success with ductal carcinomas in situ. Indeed, if dealt with adequately, such lesions should almost never affect the patient's long-term survival.

Abstract
Clinical and pathological heterogeneity of breast cancer hinders selection of appropriate treatment for individual cases. Molecular profiling at gene or protein levels may elucidate the biological variance of tumors and provide a new classification system that correlates better with biological, clinical and prognostic parameters. We studied the immunohistochemical profile of a panel of seven important biomarkers using tumor tissue arrays. The tumor samples were then classified with a monothetic (binary variables) clustering algorithm. Two distinct groups of tumors are characterized by the estrogen receptor (ER) status and tumor grade (p = 0.0026). Four biomarkers, c-erbB2, Cox-2, p53 and VEGF, were significantly overexpressed in tumors with the ER-negative (ER-) phenotype. Eight subsets of tumors were further identified according to the expression status of VEGF, c-erbB2 and p53. The malignant potential of the ER-/VEGF+ subgroup was associated with the strong correlations of Cox-2 and c-erbB2 with VEGF. Our results indicate that this molecular classification system, based on the statistical analysis of immunohistochemical profiling, is a useful approach for tumor grouping. Some of these subgroups have a relative genetic homogeneity that may allow further study of specific genetically-controlled metabolic pathways. This approach may hold great promise in rationalizing the application of different therapeutic strategies for different subgroups of breast tumors.

Abstract
OBJECTIVE To review the cytologic and subsequent histologic findings in intraductal mammary adenocarcinoma (ductal adenocarcinoma in situ) (DCIS) to evaluate the role of aspiration biopsy (AB) in identifying and grading the disease. STUDY DESIGN AB smears and tissue sections from 43 women with pure DCIS who underwent preoperative AB were reviewed. Smears were assessed for cellularity, cellular arrangement (including dissociation, nuclear size and pleomorphism), and presence of nucleoli and necrosis. RESULTS Of the 43 cases, 22 were high grade (HG) DCIS, 7 cases were intermediate grade (IG), and 14 cases were low grade (LG). Cytologic findings of HG DCIS was as follows: high cellularity (22/22), clusters of pleomorphic cells with large nuclei and increased nuclear/cytoplasmic ratios (22/22), single cells (20/22), prominent nucleoli (22/22) and necrosis (diffuse in 15/22, focal in 7/22). All LG cases had moderately to highly cellular smears with cohesive, 3-dimensional sheets of uniform, small cells with inconspicuous nucleoli arranged around a central lumen, forming "punched-out" spaces. Single cells were prominent in 2 of 14 cases. IG DCIS showed intermediate features between LG and HG DCIS: 3-dimensional sheets with punched-out spaces, abundant single cells, moderate pleomorphism and focal necrosis. CONCLUSION HG DCIS is easily identifiable on AB smears; however, distinction from invasive carcinoma may not be possible. The cytologic diagnosis of LG DCIS is difficult, and 50% of our cases were called atypical on AB. Recognition of cohesive cellular arrangements with crowding and punched-out spaces is crucial as single cells and prominent atypia are often lacking.

Abstract
PURPOSE To evaluate the clinical usefulness of multislice helical CT (MSCT) for assessing breast cancer extent. MATERIALS AND METHODS MSCT was performed in 70 patients with Tis/T1 breast cancer [12 ductal carcinoma in situ (DCIS) and 58 invasive carcinoma]. The distribution pattern of contrast enhancement (CE) was classified into five categories: solitary lesion (localized area of CE), grouped lesion (satellite: localized CE with linear and/or spotty enhancement; crowded: clustered spotty enhancement), separated lesion (multifocal foci of CE), mixed lesion (grouped lesion with multifocal foci), and diffuse lesion (diffuse CE). RESULTS Solitary lesion was seen in five cases of DCIS, 27 invasive carcinomas without intraductal spread (IDS), six invasive carcinomas with IDS, and one multicentric cancer. Grouped lesion was seen in six DCIS and 15 invasive carcinomas with IDS. Separated lesion was seen in one case of invasive carcinoma and fibroadenoma, and three multifocal/multicentric cancers. Mixed lesion was seen in two multicentric cancers. Diffuse lesion was seen in one case of DCIS and three invasive carcinomas. The coincident rate between MSCT pattern and histologic distribution was 85.7% (60/70). In solitary and grouped lesions, accuracy for the detection of tumor extent with a deviation of less than 2 cm in length was 91.7% (55/60). CONCLUSION MSCT is extremely accurate in the diagnosis of IDS and the multicentricity of breast cancer.

Abstract
AIMS To compare the morphological and immunohistochemical characteristics of oestrogen receptor (ER)-negative and ER-positive ductal carcinoma in situ (DCIS) of the breast, in an attempt to establish more objective criteria for the classification of DCIS. METHODS AND RESULTS Sections of 64 cases of in-situ carcinoma of the breast were stained for ER, progesterone receptors (PgR), androgen receptors (AR), c-erbB-2 and p53, using the immunoperoxidase technique. The cases included 60 DCIS and four lobular carcinoma in situ (LCIS). Four DCIS lesions were associated with foci of microinvasion. The 60 DCIS cases included 31 high grade, 23 intermediate grade and six low grade. Twenty-four DCIS cases (40%) were ER-negative and 36 were positive. ER negativity was significantly associated with high nuclear grade (88% versus 27% for ER-positive cases, P < 0.001), PgR negativity (100% versus 25%, P < 0.001), c-erbB-2 positivity (79% versus 14%, P < 0.001) and p53 positivity (58% versus 6%, P < 0.001). There was no difference between ER-negative and -positive DCIS as regards AR expression, with 91% of cases in each group being AR-positive. Of the four cases of DCIS with microinvasion, three were ER- and PgR-negative, all four were c-erbB-2-positive and AR-positive and one was p53-positive. None of the four LCIS was ER, PgR or AR-negative and none was c-erbB-2- or p53-positive. CONCLUSIONS There is a highly significant direct relationship between ER negativity in DCIS and high nuclear grade, PgR negativity and c-erbB-2 and p53 positivity. We suggest that immunohistological assessment of ER status may help in providing a more objective way of classifying DCIS.

Abstract
Ductal carcinoma in situ (DCIS), accounting for 15-25% of all breast cancers, is frequently diagnosed by mammographic examination. This heterogeneous disease requires a rigorous local treatment based, in about two-third of cases, on conservative surgery and radiotherapy. DCIS are currently classified on the basis of nuclear grade. Most lesions, and especially high nuclear grade DCIS, are limited to one quadrant. Micropapillary DCIS are likely to be of larger size/extent and thus a conservative approach is often difficult. A careful pathological examination of an oriented excisional biopsy is a pre-requisite for optimal therapy.

Abstract
Intraductal epithelial proliferations of the breast are at present classified into three groups; distinction is made histologically and clinically between usual epithelial hyperplasia and atypical ductal hyperplasia (ADH) and between ADH and ductal carcinoma in situ (DCIS). Although evidence indicates that these boundaries are not ideal on a morphological, immunohistochemical, or genetic basis, this three-tier system is accepted and used at present. The current definitions, histological features, and system of classification of ADH and DCIS are described in this manuscript.

Abstract
Prior to the current mammographic era, ductal carcinoma in situ (DCIS) usually presented as a large mass, was classified morphologically by architecture, and treated by mastectomy. The introduction of screening mammography led to an increase in the incidence of DCIS, a decrease in the average size of DCIS, and an increased emphasis on its heterogeneous nature. Thus, a reproducible and prognostically relevant classification system for DCIS is necessary. The ultimate goal of this classification is proper selection of patients for whom lumpectomy would suffice rather than mastectomy. Features to evaluate include: extent and size of disease, adequacy of resection margins, and histology. While none of the proposed histological classification systems were endorsed at the recent Consensus Conference on the Classification of DCIS, nuclear grade was the most important feature common to most of them. Architecture was given secondary importance. By definition, DCIS is a non-invasive clonal proliferation of epithelial cells originating in the terminal duct lobular unit, which would be expected to be monomorphic; however, it is the degree of nuclear pleomorphism that is primarily used to separate DCIS into low, intermediate, and high grades. Architecturally, DCIS has been divided into the following types: comedo, solid, cribriform, micropapillary, and papillary. Different architectural patterns and grades may be present in a given particular case; however, some combinations of patterns occur more frequently than others. Interobserver studies have shown nuclear grading to be interpreted with greater consistency than architecture, and nuclear grading methods have correlated with biological and molecular marker studies.

Abstract
In a study of invasive breast cancer, multiple correspondence analysis (MCA) revealed clustering of eight pathobiological variables. Two different phenotypes were distinguished by an index calculated on the basis of the variables (histologic grade, necrosis, lymphoid infiltration, number of mitosis and expression of c-erbB-2, p53, progesterone receptor and Bcl-2). Phenotype A lesions share most of the features of normal breast tissue. Phenotype B looks more malignant, has a higher early recurrence rate and is more frequently seen in younger patients. Our aim was to see if ductal breast carcinoma in situ (DCIS) could be divided into the same phenotypes. One hundred and eighty DCIS were investigated. Association between the eight variables was studied in 2 x 2 models. The phenotype index was calculated by summing weights for the variables in the MCA. All variables were associated, except Bcl-2. DCIS was divided in two phenotypes. Thirty-three tumours were Phenotype A and 147 Phenotype B. The mean age at diagnosis was 65.5 and 58.4 years for Phenotypes A and B, respectively (p = 0.0012). No difference regarding local relapse free survival was seen. Two phenotypes were distinguished in DCIS, similar to invasive breast cancer. In an earlier study, 45% of the invasive cancers were classified as Phenotype B. In this study, 82% of DCIS were Phenotype B. This may indicate that invasive breast cancer of Phenotype B is derived from DCIS of Phenotype B. The distribution of DCIS phenotypes with a small proportion of Phenotype A DCIS may be due to that Phenotype A DCIS is less likely to be detected by mammography, or that some invasive breast cancers of Phenotype A progress to invasiveness without passing the in situ phase.

Abstract
BACKGROUND AND OBJECTIVE Occult breast cancer is a kind of specific seldom clinically seen breast cancer. This study was designed to investigate the diagnosis and treatment of the patients with breast cancer. METHODS Retrospective study was conducted in 7 cases of occult breast cancer from May 1990 to May 2001. RESULTS All cases were female and account for 0.59% of the total breast cancer treated in the same period. Axillary node enlargement was presented as first sign and no breast mass was palpable in physical examination. Fine needle aspiration or excisional biopsy revealed metastatic adenocarcinoma before surgery. All cases were taken mammography and 1 case was suspicious of malignancy. 3 cases were taken ultrasonography and 1 case was suspicious of malignancy. 5 cases underwent radical mastectomy and 2 cases underwent modified radical mastectomy. Pathological examination of the removed specimen found the primary breast cancer leison in 4 case and showed infiltrative carcinoma in 3 cases and intraductal carcinoma in 1 case. After surgery, 2 cases received radiotherapy plus chemotherapy, 5 case received chemotherapy and 4 case received tamoxifen therapy. All case were still alive and 3 cases survived over 54 months and 1 case survived for 7 years. CONCLUSION Occult breast cancer should be considered when axillary lymph node is enlarged in female. Fine needle aspiration and excisional biopsy are helpful in pathologic diagnosis preoperatively. Mammography and ultrasonography have low sensitivity in identifying primary tumor. Radical or modified radical mastectomy with adjuvant radiotherapy and chemotherapy is a suitable choice for the patients with occult breast cancer and the prognosis is superior or similar to those patients who with palpable mass both in breast and axillary.
