Abstract
OBJECTIVES To investigate human epidermal growth factor receptor 2 (HER2)-positive nonpleomorphic invasive lobular carcinoma (ILC), which has rarely been addressed. METHODS Clinicopathologic characteristics and follow-up of HER2-positive nonpleomorphic ILCs were collected and compared to those of HER2-negative counterparts. RESULTS Twenty-one cases of HER2-positive nonpleomorphic ILCs were identified, 6.3% of the study population. Compared to HER2-negative nonpleomorphic ILC, patients with HER2 positivity were older (P < .05), likely to be hormonal receptor negative (P < .01), and had higher histologic grade and angiolymphatic invasion (P < .01). HER2 positivity in nonpleomorphic ILCs was associated with higher recurrence/metastasis with hazard ratio of 2.03 (P < .05). No patient who received neoadjuvant therapy achieved pathologic complete response, and HER2-targeted therapy tended to reduce recurrence/metastasis in patients with HER2-positive nonpleomorphic ILC. CONCLUSIONS Our results highlight the existence of HER2 positivity in nonpleomorphic ILCs and reinforce that HER2 is associated with worse prognosis in nonpleomorphic ILC.

Abstract
Aims and background p53, c-erbB-2 and Ki-67 protein expression and microvessel density (MVD) determined by CD34 antibody were evaluated by immunohistochemistry and their correlation with clinicopathological parameters including estrogen (ER) and progesterone (PR) receptor status and survival were investigated in patients with axillary lymph node-negative infiltrating ductal breast carcinoma. Methods The study population consisted of 47 patients with axillary lymph node-negative infiltrating ductal breast carcinoma. Results p53 and c-erbB-2 expression was detected in 36.2% and 31.9% of patients, respectively. Median Ki-67 expression was 10%. There were no statistically significant differences in the distribution of p53, Ki-67 and c-erbB-2 protein expression in relation to the age of the patients or to the size, histological grade or ER and PR status of the tumors. p53 protein expression correlated positively with c-erbB-2 and Ki-67 protein expression (P <0.05). The mean MVD was 63.65 ± 29.1 and it correlated positively with histological grade and Ki-67 expression (P <0.05). Survival analysis revealed that age, tumor size, p53 and c-erbB-2 expression and PR status had no significant prognostic impact, whereas histological grade, proliferative activity and angiogenic activity were significant prognostic factors. Although ER-positive patients had a statistically significant overall survival advantage, the difference in disease-free survival was not significant. Conclusion In axillary lymph node-negative breast carcinoma the histological grade and the proliferative and angiogenic activity of the tumor could be useful prognostic indicators.

Abstract
Lobular carcinoma in situ (LCIS) is considered to be a risk factor for the development of invasive breast carcinoma, but it may also be a non-obligate precursor to invasive lobular carcinoma (ILC). Many LCIS lesions do not progress to ILC, and the molecular changes that are necessary for progression from LCIS to ILC are poorly understood. Disruption in the E-cadherin complex is the hallmark of lobular lesions, but other signaling molecules, such as PIK3CA and c-src, are consistently altered in LCIS. This review focuses on the molecular drivers of lobular carcinoma, a more complete understanding of which may give perspective on which LCIS lesions progress, and which will not, thus having immense clinical implications.

Abstract
Breast cancer is the most diagnosed cancer in women worldwide. Epidemiological studies have suggested a possible causative role of alcohol consumption as a risk factor for breast cancer. However, such conclusions should be interpreted with considerable caution for several reasons. While epidemiological studies can help identify the roots of health problems and disease incidence in a community, they are by necessity associative and cannot determine cause and effect relationships. In addition, all these studies rely on self-reporting to determine the amount and type of alcoholic beverage consumed, which introduces recall bias. This is documented in a recent study which stated that the apparent increased risk of cancer among light-moderate drinkers may be "substantially due to underreporting of intake." Another meta-analysis about alcohol and breast cancer declared "the modest size of the association and variation in results across studies leave the causal role of alcohol in question." Furthermore, breast cancer develops over decades; thus, correlations between alcohol consumption and breast cancer cannot be determined in epidemiological studies with windows of alcohol exposure that captures current or recent alcohol intake, after clinical diagnosis. Numerous risk factors are involved in breast carcinogenesis; some are genetic and beyond the control of a woman; others are influenced by lifestyle factors. Breast cancer is a heterogeneous and polygenic disease which is further influenced by epigenetic mechanisms that affect the transciptomes, proteomes and metabolomes, and ultimately breast cancer evolution. Environmental factors add another layer of complexity by their interactions with the susceptibility genes for breast cancer and metabolic diseases. The current state-of-knowledge about alcohol and breast cancer association is ambiguous and confusing to both a woman and her physician. Confronting the huge global breast cancer issue should be addressed by sound science. It is advised that women with or without a high risk for breast cancer should avoid overconsumption of alcohol and should consult with their physician about risk factors involved in breast cancer. Since studies associating moderate alcohol consumption and breast cancer are contradictory, a woman and her physician should weigh the risks and benefits of moderate alcohol consumption.

Abstract
Vasohibin‑2 (VASH2) is an angiogenic factor, and has been previously reported to be a cancer‑related gene, with cytoplasmic and karyotypic forms. In the current study VASH2 expression in human breast cancer tissue and adjacent non‑cancerous tissue was investigated with immunohistochemistry. MCF‑7 and BT474 human breast cancer cells were transfected with lentiviral constructs to generate in vitro VASH2 overexpression and knockdown models. In addition, BALB/cA nude mice were inoculated subcutaneously with transfected cells to generate in vivo models of VASH2 overexpression and knockdown. The effect of VASH2 on cell proliferation was investigated using a bromodeoxyuridine assay in vitro and immunohistochemistry of Ki67 in xenograft tumors. Growth factors were investigated using a human growth factor array, and certain factors were further confirmed by an immunoblot. The results indicated that the expression level of cytoplasmic VASH2 was higher in breast cancer tissues with a Ki67 (a proliferation marker) level of ≥14%, compared with tissues with a Ki67 level of <14%. VASH2 induced proliferation in vitro and in vivo. Four growth factors activated by VASH2 were identified as follows: Fibroblast growth factor 2 (FGF2), growth/differentiation factor‑15 (GDF15), insulin‑like growth factor‑binding protein (IGFBP)3 and IGFBP6. FGF2 and GDF15 may contribute to VASH2‑induced proliferation. The current study identified a novel role for VASH2 in human breast cancer, and this knowledge suggests that VASH2 may be a novel target in breast cancer treatment.

Abstract
Ductal carcinoma in situ (DCIS) of the breast is a potentially invasive neoplasm. Risk factors include high estrogen states such as use of oral contraceptive (OC) pills, nulliparity, advanced age at first birth, and also family history and genetic mutations. The incidence of this usually clinically silent condition has risen in the past few decades due to widespread screening and diagnostic mammography, with final diagnosis confirmed by biopsy. At present, treatment options include total or simple mastectomy or lumpectomy with radiation. Adjuvant therapy includes antiestrogens like tamoxifen and human epidermal growth factor receptor 2 (HER2) suppression therapy. With the latest advances in chemotherapy and better understanding on the pathogenesis of the lesion, it is anticipated that more effective modalities of treatment may soon be available.

Abstract
BACKGROUND This study aimed to show the localization of estrogen / progesterone receptors, human epidermal growth factor receptor 2 (Her-2) and protein 53 (p53) by immunohistochemistry in a series of consecutive breast cancer patients. MATERIALS AND METHODS The study covered invasive breast cancers from 299 patients presenting at the Oncogenetic Clinic and Pathology Centers of Ahwaz Jondishapour University of Medical Sciences Hospital in Iran during the time period from 2009 to 2011. The Scarff-Bloom Richardson scoring method was used. RESULTS Of the 299, 27% (80/299) were <40, 33% (100/299) were 41-50, and the remaining 40% (119/299) were>50 years old. The highest incidence of breast cancer in this study population was in the group of more than 50 year age, and the most common histological type of breast cancer was the invasive ductal carcinoma, which accounted for 68% (203/299) of the cases. Out of possible total of 207, 6% (13/207), 41% (85/207), and 53% (109/207) were scored as grade ?, ??, ???, respectively. CONCLUSION Our findings demonstrated a lack of association between labeling for the markers studied and tumor size and age of the patients. We confirmed an association between ER labeling and nuclear grade of breast cancer. The conflicting results obtained compared with the literature be because of differences in the immunohistochemical techniques applied in the various studies and to the scoring systems used.

Abstract
CONTEXT In situ carcinomas of the breast constitute 15% to 30% of all newly diagnosed breast cancer cases; 80% of these in situ lesions belong to the ductal carcinoma in situ (DCIS) category. Similar to invasive breast carcinomas, DCIS is not a single disease but rather many distinct diseases with different histopathologic and molecular characteristics, a propensity to progress to invasive disease, and differential response to treatment. OBJECTIVE To review the classic pathologic parameters of clinical significance and the differential diagnosis of the DCIS lesions, present our new understanding of the importance of biomarkers, and discuss innovative approaches for targeted therapy in DCIS. DATA SOURCES Extensive review of the relevant peer-reviewed literature. CONCLUSIONS In DCIS, improved understanding of the underlying biologic pathways of tumor progression is expected to lead to more accurate classification and innovative targeted treatment approaches for the management of these lesions.

Abstract
BACKGROUND Ki67 is an immunohistochemical proliferation marker in many types of cancer and has been widely studied among breast cancer patients mostly through retrospective studies. METHODS The MEDLINE/PubMed database was searched for publications with the medical subject heading 'Ki 67' and the key words 'breast', 'cancer', and 'prognosis'. We restricted our search to articles published until 2012. RESULTS In this review, we included 78 articles and abstracts that were accessible and available in English. An effort to further explain the role of Ki67 in the prognosis of breast cancer has been made. CONCLUSIONS The debate on the prognostic role of Ki67 in breast cancer is still open, although most of the studies have established a relation between Ki67 and overall and disease-free survival. Further research should be made in order to establish Ki67 as a standard prognostic marker in breast cancer.

Abstract
There are numerous growing evidences of resemblance between carcinomas of the breast and prostate. A total of 45 cases of these two hormone-dependent cancers along with appropriate controls were subjected for status of epidermal growth factor receptors as well as serum lipid profile. Paraffin embedded tissue sections from aforesald tumours were analysed by immunohistochemical staining for epidermal growth factor receptor (EGF-R), c-erbB-2 oncoprotein, estrogen receptor (ER) and progesterone receptor (PgR). Sera from same individuals were studied for serum lipid profile analysis. The study revealed that immunoexpression of all receptor proteins (EGF-R). c-erbB-2 was significantly higher in breast carcinoma. In addition, mean levels of triglycerides, total cholesterol, LDL-cholesterol were found to be significantly elevated while the level of HDL-cholesterol was observed to be lower among patients with breast cancer as compared to matched controls. Further, ER-positive breast cancer cases have significantly higher mean level of HDL-cholesterol when compared with ER-negative breast cancer patients. Contrary to this, no alteration in different serum lipid fractions was noticed among the patients with prostate cancer. However, a positive relationship was noticed between immunoexpressions of EGF-R and c-erbB-2 in prostate cancer.

Abstract
Ductal carcinoma in situ (DCIS) of the breast is a heterogeneous neoplasm with invasive potential. Risk factors include age, family history, hormone replacement therapy, genetic mutation, and patient lifestyle. The incidence of DCIS has increased due to more widespread use of screening and diagnostic mammography; almost 80% of cases are diagnosed with imaging with final diagnosis established by biopsy and histological examination. There are various classification systems used for DCIS, the most recent of which is based on the presence of intraepithelial neoplasia of the ductal epithelium (DIN). A number of molecular assays are now available that can identify high-risk patients as well as help establish the prognosis of patients with diagnosed DCIS. Current surgical treatment options include total mastectomy, simple lumpectomy in very low-risk patients, and lumpectomy with radiation. Adjuvant therapy is tailored based on the molecular profile of the neoplasm and can include aromatase inhibitors, anti-estrogen, anti-progesterone (or a combination of antiestrogen and antiprogesterone), and HER2 neu suppression therapy. Chemopreventive therapies are under investigation for DCIS, as are various molecular-targeted drugs. It is anticipated that new biologic agents, when combined with hormonal agents such as SERMs and aromatase inhibitors, may one day prevent all forms of breast cancer.

Abstract
SUMMARY Ductal carcinoma in situ (DCIS) is a preinvasive breast cancer in which the proliferations of malignant ductal epithelial cells have not breached the ductal basement membrane. Currently there is controversy over the optimum management of DCIS, with suggestions that there may be an element of ‘overdiagnosis’ of some low-risk cases that may never progress to invasive cancer within a patient’s lifetime. This review discusses the biology and natural history of DCIS and current management strategies, addresses the risk factors for recurrence and how these can be minimized, highlights areas of controversy and suggest the possible direction of future research.

Advances in breast cancer control will be greatly aided by early detection so as to diagnose and treat breast cancer in its preinvasive state prior to metastasis. For breast cancer, the second leading cause of cancer-related death among women in the United States, early detection does allow for increased treatment options, including surgical resection, with a corresponding better patient response. Unfortunately, however, many patients' tumors are diagnosed following metastasis, thus making it more difficult to successfully treat the malignancy. There are, at present, no existing validated plasma/serum biomarkers for breast cancer. Only a few biomarkers (such as HER-2/neu, estrogen receptor, and progesterone receptor) have utility for diagnosis and prognosis. Thus, there is a great need for new biomarkers for breast cancer. This paper will focus on the identification of new serum protein biomarkers with utility for the early detection of breast cancer.

Abstract
The management of ductal intraepithelial neoplasia (DIN) has substantially changed over the past 30 years, as its incidence has increased (from 2-3% to more than 20%), mainly due to the widespread use of mammography screening. This article describes not only the more widespread theoretical concepts on DIN but also the differences in the practical applications of the theory between different countries, different oncology specialists, and different cancer centers. Papers related to the international multicentre-randomized trials and retrospective studies were analyzed. We include articles and papers published between 1993 and 2010 related to patients with DIN, and abstracts and reports from MEDLINE and other sources were indentified. The standard of care for DIN consists of (a) breast conservative surgery (mastectomy is still indicated in large lesions--masses or microcalcifications--in about 30% of cases); (b) radiotherapy (RT) after conservative surgery, and (c) medical treatment in estrogen receptors-positive patients. However, most studies have shown significant differences between theory and practical application. Moreover, there are differences regarding (a) the indications of sentinel lymph node biopsy, (b) the definition and identification of low-risk DIN subgroups that can avoid RT and tamoxifen, and (c) the research into new alternative drugs in adjuvant medical therapy. A general agreement on the best management of DIN does not exist as yet. New large trials are needed in order to define the best management of DIN patients which is (in most respects) still complex and controversial.

Abstract
Both increased estrogen receptor alpha (ER(alpha)) expression and germline disruption of one p53 allele increase breast cancer risk in women. Genetically engineered mouse models of deregulated ER(alpha) expression and p53 haploinsufficiency were used to investigate similarities and differences of each genetic lesion alone and in combination on mammary preneoplasia development. Each genetic lesion independently and in combination led to development of age-dependent preneoplasia, but the highest prevalence was found in compound mice with increased ER(alpha) expression coupled with p53 heterozygosity. All genetic lesions were associated with extracellular signal-regulated kinase 1/2 activation; however, only p53 heterozygous and compound mice showed increased levels of phosphorylated AKT and decreased p27 expression. The highest levels of cell proliferation were found in compound mice, but increased levels were also found with either increased ER(alpha) expression or p53 heterozygosity. Mice with increased ER(alpha) expression showed predicted higher levels of nuclear-localized ER(alpha), but this was attenuated in compound mice in association with a relative increase in Src phosphorylation. Parity protection was limited to p53 heterozygous mice and not found in mice with increased ER(alpha) alone. In summary, increased and deregulated ER(alpha) collaborates with p53 heterozygosity in increasing the risk of mammary preneoplasia development.

Abstract
Uncontrolled proliferation is a defining feature of the malignant phenotype. Ki67 is a marker for proliferating cells and is overexpressed in many breast cancers. Atypical hyperplasia is a premalignant lesion of the breast (relative risk approximately 4.0). Here, we asked if Ki67 expression could stratify risk in women with atypia. Ki67 expression was assessed immunohistochemically by digital image analysis in archival sections from 192 women with atypia diagnosed at the Mayo Clinic 1/1/67-12/31/91. Risk factor and follow-up data were obtained via study questionnaire and medical records. Observed breast cancer events were compared to population expected rates (Iowa SEER) using standardized incidence ratios (SIRs). We examined two endpoints: risk of breast cancer within 10 years and after 10 years of atypia biopsy. Thirty-two (16.7%) of the 192 women developed breast cancer over a median of 14.6 years. Thirty percent (58) of the atypias had >or=2% cells staining for Ki67. In these women, the risk of breast cancer within 10 years after atypia was increased (SIR 4.42 [2.21-8.84]) but not in those with <2% staining. Specifically, the cumulative incidence for breast cancer at 10 years was 14% in the high Ki67 vs. 3% in the low Ki67 group. Conversely, after 10 years, risk in the low Ki67 group rose significantly (SIR 5.69 [3.63-8.92]) vs. no further increased risk in the high Ki67 group (SIR 0.78 [0.11-5.55]). Ki67 appears to be a time-varying biomarker of risk of breast cancer in women with atypical hyperplasia.

Abstract
AIMS To determine the status of oestrogen receptor (ER) subtypes (ERalpha and ERbeta) in lobular carcinoma in situ (LCIS) of the breast. METHODS AND RESULTS Forty-seven cases of LCIS and six cases with normal breast lobules were subjected to immunohistochemistry and evaluated for ERalpha, ERbeta and progesterone receptor (PR) expression. mRNA for ERalpha, ERbeta1 and ERbeta2 were quantified in LCIS and normal lobules using laser microdissection coupled with real-time polymerase chain reaction. LCIS showed a higher level of steroid receptor protein expression than normal lobules. There was no difference in ERbeta1 gene or ERbeta protein expression between normal lobules, pure LCIS, or LCIS associated with invasive breast cancer. No significant difference in expression of either ERalpha or ERbeta was found between pure LCIS and LCIS associated with invasive cancer. However, PR was significantly lower in those cases of LCIS with associated invasive than in those without synchronous invasive disease. CONCLUSIONS Increased expression of steroid receptors in LCIS suggests their possible role in the biology of LCIS and, for PR, could influence the predisposition of women diagnosed with LCIS to develop invasive breast carcinoma.

Abstract
The management of precancerous lesions of the breast has become a considerable clinical problem in the past 20 years, mostly as a consequence of increased detection due to the introduction of mammographic screening. It is not possible to identify with absolute certainty which of these lesions will progress to invasive carcinoma, and tailoring the treatment according to each individual case remains a challenge. There is a particular dilemma for surgeons, who must balance the risk of resecting too much and causing unnecessary cosmetic damage, or resecting too little and leaving an increased risk of recurrence. Further knowledge in the field of predictive and prognostic factors together with the development of gene-profiling techniques will, hopefully, provide answers to these questions. Among precancerous lesions of the breast, particular attention should be paid to ductal carcinoma in situ or intraductal carcinoma, appropriate treatment of which is crucial to prevent invasive breast cancer. Nearly all possible combinations of surgery, radiotherapy and medical treatments (anti-estrogens) have been tested in different clinical trials, but the situation is far from satisfactory. We believe that an important contribution can come from oncoplastic surgery, which is the application of plastic and reconstructive surgical techniques to ensure both radical excision of the disease and acceptable cosmetic outcomes.

Abstract
Tumor growth is the net result of cell proliferation and cell death. To investigate the relationship between these phenomena in ductal carcinoma in situ (DCIS), we studied proliferation index (PI) in DCIS in relation to the expression of two proteins involved in the regulation of cell death, bcl-2 and p53. Thirty-nine consecutive cases of DCIS were studied. PI was determined using immunolabeling with the monoclonal antibody MIB-1. The proportion of MIB-1-positive nuclei among 500 tumor cell nuclei was determined for each case and constituted the PI. All cases were also assessed immunohistochemically for bcl-2 and p53 protein expression. DCIS cases were graded using the criteria of Holland et al. PI ranged from 0 to 57% (mean 11.2%, median 4.6%). PI was significantly lower in well-differentiated and intermediately differentiated DCIS cases (mean 7.3% and 4.8%, respectively) than in poorly differentiated lesions (mean 24%, p = 0.01). PI was significantly lower in bcl-2-positive cases than in bcl-2-negative cases (mean PI for bcl-2-positive cases 6% and for bcl-2-negative cases 26%, p = 0.01). PI was higher in lesions expressing the p53 protein than in p53 negative cases (19% versus 8.3%), but this difference did not reach statistical significance. PI was also examined in relation to combinations of bcl-2 and p53 expression. Twenty-five of the DCIS lesions (64%) showed the bcl-2-positive/p53-negative phenotype which is similar to that seen in normal breast tissue and benign lesions and can be considered the "physiologic" combination. Among these cases the mean PI was 6.4%. In contrast, 14 cases showed "aberrant" combinations of bcl-2 and p53 expression suggesting dysregulated control of apoptosis. Among these cases the mean PI was 19.6% (p = 0.03). The highest mean PI was in cases with the bcl-2-negative/p53-positive phenotype (PI = 29.7%). DCIS lesions with the physiologic bcl-2-positive/p53-negative phenotype have low PI. In contrast, DCIS lesions with "aberrant" bcl-2/p53 phenotypes have high PI. This combination may favor tumor growth and progression in DCIS.

Abstract
Ductal carcinoma in situ (DCIS) is commonly diagnosed today, mainly due to widespread use of screening mammography. Despite a better understanding of its biological behavior, many issues regarding its optimal management remain controversial. The biological behavior of DCIS has been associated with distinct molecular and histological features (such as expression of COX2, Ki67, c-erbB2, p53 mutation, presence or absence of comedonecrosis, nuclear grade, hormone receptor status, etc.). Recent advances in the diagnosis of DCIS include using magnetic resonance imaging, and the use of stereotactic-guided directional vacuum-assisted biopsy (DVAB). Ductoscopy and ductal lavage have a limited role in the management of DCIS. Surgical treatment of DCIS includes simple local excision to various forms of wider excision (segmental resection or quadrantectomy), or even mastectomy (either simple or skin-sparing). Radiotherapy following breast-conserving surgery significantly reduces local recurrence rates. Axillary lymph node dissection is not required for the management of DCIS; however, during the last decade, sentinel lymph node biopsy is increasingly used to exclude the presence of axillary metastases (when invasive disease is present within the DCIS). This approach has many advantages (including the avoidance of a second surgery if invasive disease is diagnosed within the DCIS) and should be considered when there is an increased probability for the presence of invasive breast cancer within the DCIS. The role of other minimally invasive methods (such as the "therapeutic" application of the DVAB technique, radiofrequency ablation, laser therapy, cryotherapy and brachytherapy) in the management of small DCIS remains unproven. Tamoxifen should be considered in the management of selected patients with DCIS, such as patients with hormone receptor positive DCIS, young patients, and patients without risk factors for potential side effects. Additionally, and controversial, there is evidence that aromatase inhibitors may be better than tamoxifen in the management of DCIS.

Abstract
Lobular neoplasia of the breast represents a group of related malignancies with clinical implications ranging from risk lesions [atypical lobular hyperplasia and lobular carcinoma in situ (LCIS)] through to aggressive invasive lesions, notably invasive pleomorphic lobular carcinoma. The diversity in lobular carcinoma is evident at the morphological level, at the molecular marker level and in cytogenetic profiles. Research in these areas is already changing the face of the disease group, for example suggesting that some lobular and ductal carcinomas are closely related and even that one of the lobular group, the tubulo-lobular carcinomas, should, in fact, be regarded as a ductal cancer. More research is required to understand the long-term pathogenic implications of a diagnosis of in situ lobular neoplasia, particularly pleomorphic LCIS, and to understand the genetics behind the well-recognized high risk of bilateral disease. For invasive carcinoma, molecular studies will allow refinement of therapy and the possibility of novel targeted therapies, for example directed against fibroblast growth factor receptor 1.

Abstract
Purpose To determine whether residual ductal carcinoma in situ (DCIS) after completion of preoperative chemotherapy affects the outcome of patients with histologically defined complete eradication of invasive cancer. Patients and Methods Retrospective analysis of a database including 2,302 breast cancer patients treated with neoadjuvant chemotherapy at The University of Texas M.D. Anderson Cancer Center between 1980 and 2004 was performed. The overall survival (OS), disease-free survival (DFS), and local recurrence-free survival were compared for patients with no residual invasive or in situ cancer (pathologic complete response [pCR]) and patients with no residual invasive cancer but persistent in situ disease (pCR+DCIS). Results The mean follow-up time was 250 months. Of the 2,302 treated patients, 78 (3.4%) had pCR, 199 (8.6%) had pCR+DCIS, and 2,025 (88%) had residual invasive cancer. For patients with pCR and pCR+DCIS, the 5-year DFS rates (87.1% in both groups) and 10-year DFS rates (81.3% v 81.7%, respectively) were similar; the 5-year OS rates (91.9% v 92.5%, respectively) and 10-year OS rates (91.8% v 92.5%, respectively) were also similar and significantly better than the rate of patients with residual invasive cancer (74.4%; P < .001). The 5-year locoregional recurrence-free survival rates were also not different between patients with pCR (92.8%; 95% CI, 86.1% to 96.4%) and patients with pCR+DCIS (90.9%; 95% CI, 77.3% to 96.5%; P = .63). Conclusion Residual DCIS in patients who experience complete eradication of the invasive cancer in the breast and lymph nodes does not adversely affect survival or local recurrence rate. Inclusion of patients with residual DCIS in the definition of pCR is justified when this outcome is used as an early surrogate for long-term survival.

Abstract
AIMS Oestrogen is a modulator of cell growth and differentiation in the breast. It mediates most of its function through members of the oestrogen receptor (ER) family, ERalpha and ERbeta. Lobular carcinoma in situ (LCIS) is a known risk factor for the development of breast cancer; however, the use of tamoxifen for prevention is based upon data for ER+ (ERalpha) LCIS associated with invasion, but limited data exist on the use of tamoxifen in cases of ER+ (ERalpha) LCIS occurring in the absence of invasive carcinoma. The aim of this study was to examine ER expression in LCIS to determine the relationship of ERalpha to ERbeta and, thereby, to determine whether it is of clinical value to measure ERbeta along with ERalpha. METHODS AND RESULTS Core biopsy specimens from 50 patients were examined retrospectively. Histology was reviewed and histological parameters were assessed. Formalin-fixed paraffin-embedded tissue was available for E-cadherin, ERalpha and ERbeta immunohistochemistry. The degree of ERalpha and ERbeta nuclear reactivity was quantified. The patients' mean age was 55 years. The mean follow-up duration was 48 months. All 50 cases of LCIS were E-cadherin-negative. All cases were ERalpha+ and ERbeta+. The staining intensity of ERbeta was strong and included staining of periductal stromal cells. The median percentage of cells immunoreactive for ERalpha was 75% and for ERbeta 70% (range 10% weak positive to 100% strong positive). There was a statistically significant relationship between ERbeta staining intensity and incidence of ipsilateral breast cancer (P = 0.010). CONCLUSIONS The presence and intensity of both stromal and glandular ERbeta immunoreactivity suggest that the action of oestrogen on LCIS is on both stromal and glandular cells. Future studies are needed to determine whether the presence of ERbeta in LCIS could be targeted to influence the treatment of this disease and perhaps alter its natural history.

Abstract
Precursors and preinvasive lesions of the breast include atypical ductal hyperplasia (ADH), ductal carcinoma in situ (DCIS), and lobular neoplasia (LN). There is a significant debate regarding the classification, diagnosis, prognosis and management of these lesions. This review article describes the current theories regarding the pathogenesis and molecular evolution of these lesions. It reviews the implication of a variety of molecules in the continuum of breast lesions: estrogen receptors (ER-alpha and ER-beta), c-erb-B2 (Her2/neu), p53, Ki-67, bcl-2, E-cadherin, transforming growth factor-beta (TGF-beta), p27 (Kip1), p16 (INK4a), p21 (Waf1), vascular endothelial growth factor (VEGF). With respect to the aforementioned molecules, this article reviews their pathophysiological importance, and puts the stress on whether they confer additional risk for invasive breast cancer or not. This knowledge has the potential to be of importance in the therapeutic decisions presenting in the common clinical practice.

Abstract
Histopathologic distinction between ductal and lobular carcinomas of the breast has been made since 1941. Together, these two subtypes account for >95% of all mammary carcinomas. With the recent advances in molecular techniques, our understanding of the biology behind these carcinomas has greatly expanded. The genomic aberrations in mammary carcinoma are highly complex and appear to be more associated with tumor grade rather than any histopathologic subtype. Protein and RNA expression profiling reveals a classification of mammary carcinoma that has some overlap with traditional histopathology and can at least partially explain clinical behavior. The goal of this review is to present what is currently known about the molecular profiles of infiltrating ductal and lobular carcinoma and how they relate to conventional histopathology and biologic behavior.

Abstract
Lobular carcinoma in situ was first described over 60 years ago. Despite the long history, it continues to pose significant difficulties in screening, diagnosis, management and treatment. This is partly due its multi-focal and bilateral presentation, an incomplete understanding of its biology and natural history and perpetuation of misconceptions gathered over the last decades. In this review, the working group on behalf of EUSOMA has attempted to summarise the current thinking and management of this interesting lesion.

Abstract
Incidence of ductal carcinoma in situ (DCIS) has increased significantly during the last decade, comprising almost 20% of all breast cancers diagnosed today. DCIS is composed of malignant breast duct epithelial cells that have clonally proliferated and accumulated within the mammary duct lumen. It comprises a group of heterogeneous tumors with varying biologic behavior rendering its classification and management challenging. By definition, DCIS does not invade through the basement membrane; it is a preinvasive malignancy and systemic disease is nonexistent. The basis of treatment is to prevent progression into an invasive cancer such as ductal carcinoma. Most current DCIS classification schemes do not predict its potential to progress to invasive disease. In this review the natural history of DCIS, as it relates to its biologic potential to progress to invasive disease, is summarized, and a broad classification system that may provide a guideline for patient management is proposed.

Abstract
BACKGROUND Ductal carcinoma in situ represents about 20% of all tumours diagnosed within mammographic screening programs. The natural history of DCIS is poorly understood, as it cannot be observed directly. Estimates of the proportion of DCIS that progress to invasive cancer, as well as factors that may influence progression, are important for clinical management. Here we review various sources of evidence regarding the natural history of DCIS. METHODS We identified relevant publications of studies on: follow-up studies of DCIS initially misdiagnosed as benign, studies of recurrence of DCIS as invasive cancer, autopsy studies, studies of risk factors for DCIS, animal studies and studies that used mathematical models to study growth of DCIS and invasive cancer. Data sources included the MEDLINE data base, searches of articles cited in key reviews and editorials. RESULTS The most direct evidence regarding the progression of DCIS to invasive cancer comes from studies where DCIS was initially misdiagnosed as benign and treated by biopsy alone. These studies suggest that between 14-53% of DCIS may progress to invasive cancer over a period of 10 or more years. The reported prevalence of undiagnosed DCIS in autopsy studies, of approximately 9%, has been used to suggest a larger reservoir of DCIS may exist in the population. All types of study designs reviewed had limitations that may bias the estimate of progression in either direction. CONCLUSION The available evidence suggests not all DCIS will progress to invasive cancer in the medium term but precise estimates of progression are not possible given the limitations of the data. Mathematical modelling of various scenarios of progression and studies of genetic factors involved in progression may shed further light on the natural history of DCIS.

Abstract
The predisposition of patients with lobular carcinoma in situ (LCIS) to develop invasive breast cancer (IBC) is well known. However, relatively little is known about the biologic characteristics, which may be involved in the development and progression of LCIS. This study evaluated 59 cases of LCIS (29 pure, 30 with synchronous IBC) for five biomarkers known to be important in IBC (ER, PgR, c-erbB-2, p53 and Ki-67 proliferation rate) by immunohistochemistry. A comprehensive analysis of loss-of-heterozygosity (LOH) was performed in 12 cases (10 pure, 2 with synchronous IBC) at 15 genetic loci on 9 chromosomes. LCIS demonstrated a low grade/favorable biophenotype that was not significantly different in cases with and without synchronous IBC (ER 98%, PgR 84%, c-erbB-24%, p53 19% and proliferation rate 2%). LOH was present in 80% of pure LCIS and the highest rates of LOH were at loci on 9p (30%), 16q (63%), 17p (33%) and 17q (50%). The clustering of LOH at these four foci suggests that inactivated tumor suppressor genes in these regions may be particularly important. LOH was present in both cases of LCIS with synchronous IBC and the LOH phenotype was shared by LCIS and IBC. Our findings suggest that five known prognostic factors in IBC do not have prognostic utility in LCIS. Multiple genetic mechanisms may be involved in the development of LCIS.

Abstract
Recent clinical data have suggested that the efficacy of tamoxifen in reducing the risk of local recurrence following lumpectomy and radiation therapy in patients with ductal carcinoma in situ (DCIS) is limited to patients with estrogen receptor (ER)-positive lesions. However, it is currently not known if HER2 protein overexpression might be associated with reduced tamoxifen benefit in patients with ER-positive DCIS, as has been suggested in patients with ER-positive invasive breast cancer and in preclinical models. Moreover, the frequency of HER2 overexpression in ER-positive ductal carcinoma in situ has not been previously evaluated in detail. To address this issue, we studied ER expression and HER2 overexpression in 148 cases of DCIS using a sensitive double immunostaining technique and assessed the frequency of ER expression and HER2 overexpression in relation to each other and in relation to DCIS grade. Overall, ER expression was seen in 114 cases (77%) and HER2 protein overexpression was seen in 42 cases (28%). Of 114 ER-positive ductal carcinoma in situ, 14 (12%) showed concurrent HER2 protein overexpression, and all 14 of these DCIS lesions were of high nuclear grade. In addition, in all 14 ER-positive DCIS cases that showed HER2 overexpression, double immunostaining demonstrated that ER and HER2 protein were coexpressed by the same neoplastic cells. We conclude that a subset of ER-positive DCIS show concomitant overexpression of HER2 protein. Whether or not HER2 overexpression is associated with a diminished response to tamoxifen in patients with ER-positive DCIS will require investigation in clinical outcome studies.

Abstract
INTRODUCTION Recommendations for adjuvant treatment of DCIS after breast conservation are controversial. We tried to identify further risk factors in a retrospective study of our own practice. PATIENTS AND METHODS Three hundred and thirty-two patients treated by breast conservation between 1978 and 2001 at the Department of General Surgery, University of Vienna were analysed. Tumour size, nuclear grade, hormone receptors, p53, her-2/neu, multifocality, microinvasion and post-operative therapy (irradiation, tamoxifen or combination) were analysed for their influence on breast recurrence. RESULTS Overall recurrence rate was 6.1% (8/132). For patients with DCIS showing high nuclear grade or negative estrogen receptor the risk for development of ipsilateral breast recurrence is significantly higher. Newer factors like p53 and her-2/neu do not have any prognostic significance. No recurrence was observed in patients treated by post-operative irradiation and tamoxifen. CONCLUSION Nuclear grade remains the most significant factor for breast recurrence after DCIS. Hormone receptor status identifies a subset of patients with more favourable prognosis.

Abstract
BACKGROUND A number of conventional histopathologic features have been associated with recurrence of ductal carcinoma in situ (DCIS) after surgery alone and are included in the Van Nuys Pathologic Classification and Prognostic Index. To the authors' knowledge, very little is known regarding the prognostic significance of the many biologic markers that have been studied in DCIS in the past decade. METHODS Clinical and pathologic data were analyzed from 151 patients who underwent wide local excision alone for DCIS that was diagnosed by mammography or as an incidental finding between 1982 and 2000. Using local disease recurrence as an endpoint, the authors sought to determine the prognostic significance of a large number of histopathologic parameters as well as biologic markers (estrogen receptor [ER], progesterone receptor [PR], p53, HER-2/neu, Ki-67, p21, and bcl-2), as determined by immunohistochemical staining of contemporary or archival tissue. RESULTS With a median follow-up of 65 months, 42 recurrences were reported to occur between 11 months and 97 months after definitive surgery. In a univariate analysis, tumor size, Van Nuys pathologic classification, and degree of necrosis demonstrated significant correlations with the rate of recurrence. Tumor size, necrosis, nuclear grade, and comedonecrosis were found to be associated significantly with the time to disease recurrence. None of the biologic markers demonstrated a significant association with the rate of recurrence or the time to disease recurrence. In a multivariate analysis, only large tumor size (Van Nuys 2 or 3) and higher degrees of necrosis (Van Nuys 2 or 3) were found to be associated significantly with both the rate of recurrence and the time to recurrence. No biologic marker showed a significant correlation with recurrence. Using Classification and Regression-Tree Analysis and Tree-Structured Survival Analysis, PR > 3.5% and bcl-2 < 97.5% were associated with a higher recurrence rate in the subgroup of patients with small tumor size (Van Nuys size 1) and higher degrees of tumor necrosis (Van Nuys 2 or 3). CONCLUSIONS The current results confirmed the value of conventional histopathologic parameters, as outlined in the Van Nuys classification system, in predicting local recurrence of DCIS. Using traditional logistic analyses, no significant correlation was found between a variety of biologic markers and disease recurrence.

Abstract
Geno-phenotypic patterns of pre-invasive and invasive lobular breast cancers and infiltrating ductal carcinomas of low, intermediate, and high grade are reviewed. One of the main differences between lobular breast cancers and ductal carcinomas is the presence of inactivating E-cadherin gene mutations in lobular breast cancers. In many other respects, lobular breast cancers and low-grade ductal carcinomas exhibit similar geno-phenotypic profiles. The development of p53 dysfunction may be a hallmark of infiltrating ductal cancers of intermediate and high grade. Sequential Her-2/neu and ras abnormalities define a subset of aggressive high-grade tumors, and the development of Rb dysfunction may define a separate subset of aggressive ductal cancers. Based on these observations, a branching molecular evolutionary model for the development and progression of breast cancer is proposed.

Abstract
Abnormalities in G1/S transition in cell cultures have been attributed to alterations in ErbB (erythroblastic leukaemia viral [v-erb-b] oncogene homologue, avian) signalling, cyclin D1 overexpression or disturbance of the p21(WAF1) (p21)-mediated cell cycle arrest induced by p53. To investigate the significance of these mechanisms on an early stage of human breast tumour growth, we studied the expression of EGFR (ErbB1), HER-2/neu (ErbB2), cyclin D1, p21 and p53 as well as oestrogen (ER) and progesterone receptor (PgR) in paraffin sections of 45 ductal carcinoma in situ (DCIS) by immunohistochemistry. Cell proliferation was assessed by immunohistochemical quantification of Ki-67. Five cases with cyclin D1 overexpression were analysed by FISH for CCND1 amplification. Increased proliferative activity was observed in 46% of DCIS. It was correlated with the expression of EGFR and HER-2/neu (p < 0.05), but neither with cyclin D1 and p21 overexpression nor with p53 accumulation. ErbB positive status was associated with p21 overexpression (p < 0.05). In addition we found a correlation between the overexpression of p21 and cyclin D1 restricted to ErbB-positive cases (p = 0.013). ErbB-negative tumours with increased proliferative activity were ER and cyclin D1 positive. No CCND1 amplification was detected in the analysed cases. In conclusion, our data support that EGFR and HER-2/neu play an important role in cell cycle control in DCIS. p21 appears to be a potential mediator of ErbB signalling. We propose that cyclin D1 could be indirectly induced by ErbB signalling through p21. Besides, ER-mediated upregulation of cyclin D1 seems to be a possible mechanism of maintaining cell proliferation in DCIS in case of EGFR- and HER-2/neu-negativity.

Abstract
The optimal management of ductal carcinoma in situ (DCIS) is controversial, due in part to our poor understanding of its natural history. We undertook to identify subgroups of DCIS based on the expression of biomarkers, which were related to the likelihood of clinical recurrence. Biomarker expression of a total of 95 DCIS lesions in a nested case-control study within a population-based cohort with up to 135 months follow-up data (median 101 months) was analysed using immunohistochemistry. ERBB2-positivity and bcl-2-, oestrogen receptor (ER)- and progesterone receptor (PR)-negativity were individually associated with the risk of clinical recurrence. The predictive value of these biomarkers was independent of cytonuclear grade. ERBB2, bcl-2, ER and PR expression were conserved in the recurrent lesions, including subsequent invasive cancers. p21-positive DCIS was also associated with clinical recurrence, independently of the associations with ERBB2/bcl-2/ER/PR expression. These data identify clinically and biologically relevant subcategories of DCIS lesions, an essential basis for improving management.

Abstract
There is currently great interest in the detection and characterization of putative precursor breast cancer lesions because of the possibility of chemoprevention. Knowledge of the biologic features of premalignant lesions, although limited, is rapidly evolving. Premalignant breast lesions have been examined for the presence of genetic alterations and for the expression of biomarkers such as the estrogen receptor (ER), Ki67, p53, and HER2/neu. Data obtained from genetic studies of precursor breast lesions clearly support the contention that genetic alterations begin quite early in selected subsets of histologically benign lesions. Although the results of biomarker expression profiles have been contradictory, most studies agree that precursor lesions significantly overexpress ER and that progressive alterations in ER expression accompany the transition of normal cells to hyperplastic lesions and carcinoma in situ. So far, the collected evidence indicates that precursor lesions in the breast demonstrate biomarker expression profiles and genetic abnormalities that are distinct from those of terminal ductal lobular units but share some of these features with invasive tumors. Future research in this field is urgently needed to identify specific biomarkers of prognostic and predictive value, which can help not only in the selection of patients for chemopreventive therapy but in monitoring the progression of high-risk lesions.

Abstract
BACKGROUND Abnormal expression of the HER-2/neu oncogene, a tyrosine kinase-type transmembrane growth factor receptor localized to chromosome 17q, has been associated with poor prognosis and the prediction of therapy response in invasive breast cancer. The comparative incidence and significance of HER-2/neu gene amplification for lobular and ductal breast cancer have not been previously characterized. DESIGN Formalin-fixed, paraffin-embedded primary breast cancer tissue sections from 71 women diagnosed with invasive lobular carcinoma were tested for HER-2/neu gene amplification by fluorescence in situ hybridization (FISH) method using the Ventana unique sequence probe (Ventana Medical Systems, Tucson, AZ). A series of 106 cases of invasive ductal carcinoma was similarly processed and tested. Lymph node status was available for 155 (88%) of the 177 cases and 82 (46%) were lymph node-negative (LN-) and 73 (41%) were lymph node-positive (LN+). Patients were treated for a mean of 65 months (range 1-169 months). RESULTS 9 of 71 (13%) cases of lobular cancer featured HER-2/neu gene amplification, whereas 51 (48%) of 106 cases of ductal cancer showed amplification (P < 0.0001). On univariate analysis of combined lobular and ductal cases, HER-2/neu gene amplification detected by FISH predicted disease-related death (P < 0.0001). HER-2/neu gene amplification also predicted disease-related death in lobular cases alone (P = 0.003), LN+ lobular cases separately (P = 0.019), and LN- and LN+ ductal cases separately and alone (P < 0.0001). Multivariate analysis of the lobular group alone revealed that LN+ status (P = 0.015) and stage (P = 0.01) were independent predictors of disease-related death, and HER-2/neu gene amplification reached near significance (P = 0.086). In the ductal carcinoma group alone, HER-2/neu gene amplification (P = 0.03), lymph node status (P = 0.0001), tumor stage (P = 0.0001), and tumor grade (P = 0.044) were independent predictors of overall disease survival. CONCLUSIONS HER-2/neu gene amplification detected by FISH was identified at a significantly lower rate in lobular compared with ductal breast cancer. HER-2/neu gene amplification when present in lobular breast cancer is a significant adverse prognostic factor.

Abstract
With the introduction of mammographic screening the incidence of ductal carcinoma in situ (DCIS) has increased to 10-15% of all breast cancers. The aim of this study was to investigate whether there were any morphological and cell biological differences between DCIS detected during the pre-screening (n = 39) as opposed to the screening period (n = 120). We could not demonstrate any statistically significant differences between the pre-screening and the screening period with regard to nuclear grade, presence of necrosis, the Van Nuys classification system, growth pattern, or cell biological factors (estrogen and progesterone receptors, c-erbB-2, p53, DNA ploidy status, Ki67, and Auer classes). These findings suggest that DCIS tumors detected during the two time periods have a similar malignant potential. DCIS detected during the screening period was further divided into the prevalence period versus the period thereafter, and symptomatic versus screening-detected asymptomatic cases. More cases with diffuse growth patterns were seen during the prevalence period than after the prevalence period, and screening-detected asymptomatic DCISs were more often 15 mm or smaller in diameter than DCISs detected symptomatically.

Abstract
All cases of ductal carcinoma in situ (DCIS) diagnosed from 1987 to 1991 in the Southern Health Care Region of Sweden, and operated upon with breast conserving treatment (BCT) with (n=66) or without (n=121) postoperative radiation (RT) were clinically followed, morphologically re-evaluated and analysed for cell biological factors (immunohistochemical assays or DNA flow cytometry). Median age at diagnosis was 58 years (range 29--83 years) and median follow-up was 62 months. Oestrogen (ER)- and progesterone receptor (PR)-negativity, c-erbB-2 overexpression, low bcl-2 expression, p53 accumulation, DNA non-diploidy and high Ki67, were strongly associated with high grade DCIS, and comedo-type necrosis. In contrast, significant associations to growth pattern (not diffuse versus diffuse) were seen only for c-erbB-2 and PgR. There was also a strong relationship between the cell biological factors, and a summary cell biological index based on principal component analysis was introduced (CBI-7). In the group that had not received postoperative RT, 31 ipsilateral local recurrences occurred (13 invasive, 18 DCIS). Ipsilateral recurrence-free interval (IL-RFI) was in univariate analyses significantly, or almost significantly, shorter for patients showing p53 accumulation, high Ki67 or low bcl-2, compared with patients with normal p53, low Ki67 and high bcl-2. The prognostic importance of the remaining cell biological factors was less pronounced. On the other hand, the index CBI-7, was a strong predictor for recurrence.

Abstract
OBJECTIVE To assess the prognostic significance of molecular biomarkers, particularly c-erbB-2 and p53, through study of prospective clinical data and archival breast cancer tissues for women accrued to the Alabama Breast Cancer Project. SUMMARY BACKGROUND DATA Defining molecular abnormalities in breast cancer is an important strategy for early detection, assessment of prognosis, and treatment selection. Evidence is strong that selective biomarkers, including c-erbB-2 and p53, have prognostic significance in breast cancer. Few studies have analyzed the prognostic significance of coexpression of biomarkers. METHODS Study patients were those accrued to the Alabama Breast Cancer Project (1975-1978) who had archival breast cancer tissues available for analysis. Criteria for entrance into the Alabama Breast Cancer Project were T1-3 breast cancer with M0 status. Age, nodal status, and histologic grade were also documented. Patients were randomized to radical versus modified radical mastectomy, and node-positive patients were also randomized to adjuvant chemotherapy (cyclophosphamide, methotrexate, and 5-fluorouracil [CMF]) versus melphalan. Archival breast cancer tissues were studied for c-erbB-2, TGF-alpha, p53, cathepsin D, bcl-2, and estrogen and progesterone receptor expression using immunohistochemistry. Survival curves were developed using the Kaplan-Meier method. Univariate analysis was performed using the log-rank test, multivariate analysis using a rank regression model. RESULTS Three hundred eleven patients were accrued to the Alabama Breast Cancer Project, and paraffin-embedded breast cancer tissues for 90 patients were available for immunohistochemical analysis of molecular biomarkers. Univariate analysis showed nodal status, c-erbB-2 expression, and p53 expression to have prognostic significance. Coexpression of c-erbB-2 and p53 was also found to have prognostic significance by the log-rank test. Multivariate analysis showed T stage, nodal status, c-erbB-2 expression, and p53 expression to have independent prognostic significance. CONCLUSIONS These data suggest that c-erbB-2 and p53 expression in breast cancer have prognostic significance. After median follow-up of 16 years, coexpression of c-erbB-2 and p53 may have more prognostic significance than traditional prognostic factors such as T stage and nodal status. Prospective study of large numbers of patients with breast cancer is encouraged to validate these findings.

Abstract
Most human invasive breast cancers (IBCs) arise from preexisting benign lesions. There are many types of benign lesions in the human breast and only a few appear to have significant premalignant potential (atypical hyperplasias and in situ carcinomas). These lesions are relatively common and only a small proportion progress to IBC. They are currently defined by their histological features and their prognosis is imprecisely estimated from indirect evidence based on epidemiological studies. Although lesions within specific categories look alike, they must possess morphologically silent biological differences motivating some to remain stable and others to progress. Understanding the biological changes responsible for the development and progression of premalignant disease is a very active area of medical research. Progress in this area may provide new opportunities for breast cancer prevention by providing strategies to treat premalignant lesions before they develop or become cancerous. A large number of biological features have been evaluated in this setting during the past decade. This review discusses a few features that appear to be particularly important and have been studied in a relatively comprehensive manner.

Abstract
Male breast cancer is uncommon; so far, only 10 cases with chromosome banding analysis have been published. We report the cytogenetic findings of two invasive breast cancers in two Caucasian men lacking a history of familial breast cancer and more than 70 years of age. Both had ductal carcinomas with lymphangiosis carcinomatosa and positive lymph nodes at diagnosis. Strong expression of estrogen receptor, weak expression of progesterone receptor, and lack of expression of androgen receptor by both tumors were demonstrated by immunohistochemistry, as well as lack of expression of p53 and C-ERB-B-2. The karyotypes were 45 approximately 46,XY,-Y[4],-7[2],+8[2],t(8;12)(q21;q24)[3], del(9)(q22)[3],del(11)(p11p14)[5],del(18)(q21)[7], t(19;20)(p10;q10)[8] [cp13] and 61 approximately 69,XXXY,-Y[3], del(2)(p21)[4],del(3)(p22q26)[3],-4,-4[5],+5,+5[5], dic(5;11)(p14;q23)[3],del(6)(q23)[4],del(8)(p21)[3],-9[4],-11[4],+ i(12)(p10)[4],-16[3],del(17)([13)[5],del(18)(q21)[4],+19[5], +20[4][cp7], respectively. Although the available data on male breast cancer are still very limited, our findings confirm that gain of an X chromosome, loss of the Y chromosome, gain of chromosome 5, and loss of material from chromosomes 17 and 18 are nonrandom aberrations in male breast cancer. Trisomy 8, characteristic of ductal carcinomas, was found in one case.

Abstract
PURPOSE To investigate the prognostic value of biomarkers in male breast carcinoma (MBC). PATIENTS AND METHODS Fifty patients (mean age, 62.2 years) with invasive ductal carcinoma were retrospectively studied. All patients received surgery; 35 had adjuvant postoperative therapy. The median follow-up was 59 months (range, 1 to 230 months). c-myc, c-erbB-2, p53, and bcl-2 proteins were immunohistochemically detected on sections from formalin-fixed, paraffin-embedded tissues using 9E11, CB11, DO7, and bcl-2 124 monoclonal antibodies (mAbs). Estrogen, progesterone, and androgen receptors were detected using specific mAbs. Cell proliferation was assessed by MIB-1 mAb. RESULTS In univariate analysis, c-myc, c-erbB-2, and p53 protein overexpression was significantly correlated with prognosis. The median survival was 107 months for c-myc-negative and 52 months for c-myc-positive patients (P =.01), 96 months for c-erbB-2-negative and 39 months for c-erbB-2-positive patients (P =.02), and 100 months for p53-negative and 33 months for p53-positive patients (P =.0008). Tumor histologic grade (P =.01), tumor size (P =.02), patient age at diagnosis (P =.03), and MIB-1 scores (P =.0004) also had prognostic value. In multivariate analysis, only c-erbB-2 and p53 immunoreactivity retained independent prognostic significance. All nine patients who did not express c-erbB-2 and p53 proteins were alive after 58 months, whereas none of the 14 patients expressing both proteins survived at 61 months follow-up (P =.0002). CONCLUSION Overexpression of c-myc, c-erbB-2, and p53 proteins may be regarded as an additional prognostic factor in MBC. The combination of c-erbB-2 and p53 immunoreactivity can stratify patients into different risk groups.

Abstract
Breast cancer is probably the result of a series of genetic events, each with its own histopathologic correlate in the hyperplasia to carcinoma sequence. The expression of breast cancer markers in hyperplasia and tumors are well known, but few studies have investigated their sequential expression among hyperplastic and cancerous lesions within the same breast. Using breast tissue obtained from a single procedure, we correlated the immunohistochemical expression of several breast cancer markers with the histopathologic stage of proliferative breast disease. We selected 14 cases in which various degrees of hyperplasia coexisted with carcinoma. Serial sections were reacted with antibodies to DF3, c-erbB-2, p53 (DO7 and CM1), B72.3, and cyclin D1. We found that within an individual breast, the number of breast cancer markers expressed increased with progression from hyperplasia to atypical hyperplasia to carcinoma. Cytoplasmic DF3 was first expressed at the level of simple hyperplasia, followed by c-erbB-2 in atypical hyperplasia. Overexpression of p53 was confined to carcinomas, and thus appeared to be a late event. B72.3 was expressed in three carcinomas and in one atypical hyperplasia, although the associated carcinoma was negative. Carcinomas that expressed cytoplasmic DF3 and c-erbB-2 were associated with atypical hyperplasias that also expressed cytoplasmic DF3 and c-erbB-2, with one and two exceptions, respectively. No specific cyclin D1 staining pattern was observed.

Abstract
This article illustrates the most common benign and malignant lesions in the breast, and is intended for the biologist working in the area of breast cancer and breast biology, not for the practicing pathologist. The atlas covers benign proliferative lesions, atypical lesions, variants of in situ cancer, the main types of invasive cancers, spindle cell lesions, and examples of vascular and lymphatic spread. Some entities are included to illustrate a point of particular relevance to the biology and histogenesis of the lesions. Some controversial diagnostic areas are considered, along with the relative risk of developing breast cancer associated with some of the proliferative lesions. The content of this atlas should be read in conjunction with the companion article by Howard and Gusterson in this issue. Their article covers the cellular origin of epithelial and stromal tumors and presents a description of some of the common benign proliferative lesions that are considered to be components of the normal spectrum of changes seen at postmortem or in biopsies.

Abstract
Ductal carcinoma in situ of the breast is the most favorable presentation of breast cancer; therefore appropriate local treatment is imperative. Intraductal carcinoma is being diagnosed more frequently with the increasing use of screening mammography. A number of pathologic features have been identified which are useful for classification and for prognostic information. In addition, the molecular pathology and its relationship to tumor behavior and prognosis is becoming more well understood. The role of axillary dissection has been examined in a number of series and is generally agreed to be unnecessary for this presentation of breast cancer, allowing many women to avoid the sequela of axillary surgery. This review discusses the use of breast conservation treatment and the evolving indications for excision alone in the treatment of ductal carcinoma in situ. The outcomes for breast conservation therapy from both randomized trials and institutional series have confirmed excellent survival rates. Salvage therapy for local recurrence is frequently successful, resulting in nearly equivalent survivals in women undergoing breast conservation therapy compared to mastectomy. In addition, intriguing but preliminary results from both breast cancer prevention studies and trials looking at the use of tamoxifen for intraductal cancer suggest a local control benefit in women using the drug.
