Abstract
The current histological classification of in-situ and invasive lobular carcinomas (ILCs) includes different morphological variants, some of which have been recently described. In this review, we will focus upon: (i) the diagnostic criteria of non-invasive lobular neoplasia and treatment implications across different countries; (ii) utility and limitations of immunohistochemistry; (iii) recently described variants of ILC; and (iv) the significance of lobular differentiation in invasive carcinoma for clinical management.

Abstract
BACKGROUND A subset of patients with ductal carcinoma in situ (DCIS) experience recurrence or progression to invasive cancer. Current clinical practice is not reliably guided by DCIS recurrence prediction, although recurrence risk for invasive breast cancer can now be assessed. We analyzed a panel of biomarkers (estrogen receptor, Her2, Ki67, p53, cyclin D1, COX-2, caveolin-1, survivin, and PPAR-γ) and DCIS histologic and clinical features to determine associations with DCIS recurrence. MATERIALS AND METHODS Seventy DCIS cases diagnosed between 1995 and 2010 were divided into 2 groups: 52 had DCIS without known recurrence after excision and 18 had DCIS with subsequent recurrence after excision as DCIS or invasive carcinoma in the ipsilateral or contralateral breast. Tissue microarrays were prepared, immunohistochemistry performed, and expression of the biomarkers scored semiquantitatively. Variables analyzed included age, tumor size, margin status, DCIS grade, necrosis, histologic type, and immunohistochemistry scores. Differences between groups were evaluated using t tests for continuous variables and Fisher exact tests for categorical variables. RESULTS Intraductal necrosis was associated with increased recurrence risk: 46% of nonrecurrent cases showed necrosis compared with 83% of those who recurred (P=0.007). Her2 (human epidermal growth factor receptor 2) and Ki67 expression distributions were significantly different between nonrecurrent and recurrent cases. Her2 was overexpressed in 14% of nonrecurrent cases compared with 50% in the recurrent cases (P=0.03). A total of 87% of nonrecurrent cases had low Ki67 staining (0% to 10%) compared with 50% among the recurrent cases (P=0.002). CONCLUSION Our results suggest that Her2 and Ki67 immunohistochemistry and the presence of intraductal necrosis aid in DCIS risk stratification.

Abstract
Ductal carcinoma in situ (DCIS) is a heterogeneous group of non-invasive lesions of the breast that result from abnormal proliferation of mammary epithelial cells. Pathologists characterize DCIS by four tissue morphologies (micropapillary, cribriform, solid, and comedo), but the underlying mechanisms that distinguish the development and progression of these morphologies are not well understood. Here we explored the conditions leading to the emergence of the different morphologies of DCIS using a two-dimensional multi-cell lattice-based model that incorporates cell proliferation, apoptosis, necrosis, adhesion, and contractility. We found that the relative rates of cell proliferation and apoptosis governed which of the four morphologies emerged. High proliferation and low apoptosis favored the emergence of solid and comedo morphologies. In contrast, low proliferation and high apoptosis led to the micropapillary morphology, whereas high proliferation and high apoptosis led to the cribriform morphology. The natural progression between morphologies cannot be investigated in vivo since lesions are usually surgically removed upon detection; however, our model suggests probable transitions between these morphologies during breast cancer progression. Importantly, cribriform and comedo appear to be the ultimate morphologies of DCIS. Motivated by previous experimental studies demonstrating that tumor cells behave differently depending on where they are located within the mammary duct in vivo or in engineered tissues, we examined the effects of tissue geometry on the progression of DCIS. In agreement with our previous experimental work, we found that cells are more likely to invade from the end of ducts and that this preferential invasion is regulated by cell adhesion and contractility. This model provides additional insight into tumor cell behavior and allows the exploration of phenotypic transitions not easily monitored in vivo. Breast cancer is a complex disease that affects women worldwide. One heterogeneous group of lesions, ductal carcinoma in situ (DCIS), often begins as a nonmalignant disease but can readily progress if left untreated. The progression of this disease is not well understood because DCIS is typically removed upon detection. Therefore, computational models might help predict whether DCIS will remain nonmalignant or progress towards invasive ductal carcinoma. Here we used a multi-cell lattice-based model to explore the relative effects of cell proliferation, death, division axis, adhesion and contractility on the development and progression of DCIS. We also examined the emergence and progression of DCIS in physiologically relevant geometries of the mammary duct. Our model suggests several plausible progressions between morphologies of DCIS, and predicts that some regions of a duct are preferential for tumor cell invasion.

Abstract
The clinicopathologic, mammographic, and sonographic findings in patients with pure ductal carcinoma in situ (DCIS) were assessed by estrogen receptor (ER) expression. After institutional review board approval, patients with pure DCIS evaluated from January 1996 to July 2009 with known ER status and available imaging were identified. Images were reviewed as per the ACR BI-RADS(®) lexicon (4th edition). Clinical, pathologic, and imaging characteristics were analyzed by ER status using t test, Chi square test, and Fisher's exact test. Of 1,219 patients with pure DCIS and known ER status identified, 1,187 with complete data were included. Mammography was performed in all 1,187 patients and sonography in 519 (44 %). There were 972 (82 %) patients with ER-positive and 215 (18 %) with ER-negative disease. ER-negative DCIS was more likely to be high grade (93 vs 44 %, p < 0.0001), associated with comedonecrosis (64 vs 29 %, p < 0.0001), and multifocal (23 vs 15 %, p = 0.009). On sonography, ER-negative DCIS was more likely to be visible (61 vs 46 %, p = 0.004), larger (mean size, 2.3 vs 1.6 cm, p = 0.006), and show posterior shadowing (53 vs 28 %, p = 0.006). Mastectomy was more frequently performed for ER-negative DCIS (47 vs 37 %, p = 0.008). Palpable DCIS was visible on sonography in 55 % of cases and mammography in 81 %. Compared with ER-positive palpable DCIS, ER-negative palpable DCIS was larger and more likely to be visible on sonography. Compared with ER-positive noncalcified DCIS, ER-negative noncalcified DCIS was less likely to be visible on mammography. ER-positive and ER-negative pure DCIS have different clinicopathologic and imaging characteristics. ER-negative DCIS is associated with worse prognostic factors than ER-positive DCIS. On sonography, ER-negative DCIS is more frequently visible than ER-positive DCIS, tends to be larger, and more frequently demonstrates posterior shadowing.

Abstract
The natural history of ductal carcinoma in situ (DCIS) is not fully elucidated, but it is recognized that DCIS is the true precursor of invasive carcinoma. Studies could show that DCIS is as heterogeneous as invasive ductal carcinoma, yet, they were unable to predict which DCIS will progress to invasion. Several biomarkers were also demonstrated to have a certain prognostic value. However, except for estrogen receptors and HER2, biomarkers are not yet widely used in clinical practice since their predictive value has not proven to be better than the grade and the classical classifying systems of DCIS. Identifying biomarkers for risk of invasiveness in DCIS could be of great value to help high risk patients through the management of their disease and to avoid overtreatment in low risk patients.

Abstract
Understanding of the biology and clinical behavior of ductal carcinoma in situ (DCIS) is currently inadequate. The aim of this comprehensive review was to identify important molecular biological markers associated with DCIS and candidate markers associated with increased risk of ipsilateral recurrence after diagnosis of DCIS. A comprehensive systematic review was performed to identify studies published in the past 10 years that investigated biological markers in DCIS. To be included in this review, studies that investigated the rate of biological expression of markers had to report on at least 30 patients; studies that analyzed the recurrence risk associated with biomarker expression had to report on at least 50 patients. There were 6,252 patients altogether in our review. Biological markers evaluated included steroid receptors, proliferation markers, cell cycle regulation and apoptotic markers, angiogenesis-related proteins, epidermal growth factor receptor family receptors, extracellular matrix-related proteins, and COX-2. Although the studies in this review provide valuable preliminary information regarding the expression and prognostic significance of biomarkers in DCIS, common limitations of published studies (case-series, cohort, and case-control studies) were that they were limited to small patient cohorts in which the extent of surgery and use of radiotherapy or endocrine therapy varied from patient to patient, and variable methods of determining biomarker expression. These constraints made it difficult to interpret the absolute effect of expression of various biomarkers on risk of local recurrence. No prospective validation studies were identified. As the study of biomarkers are in their relative infancy in DCIS compared with invasive breast cancer, key significant prognostic and predictive markers associated with invasive breast cancer have not been adequately studied in DCIS. There is a critical need for prospective analyses of novel and other known breast cancer molecular markers in large cohorts of patient with DCIS to differentiate indolent from aggressive DCIS and better tailor the need and extent of current therapies.

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
Human breast tissue can give rise to hyperplasias, atypical hyperplasias, and in situ carcinomas originating in a terminal duct-lobular unit (TDLU). These entities are associated with increased risk of subsequent development of invasive carcinoma. Human breast carcinomas arise via intermediate steps known as precursor or premalignant lesions. However, it is difficult to perform stepwise observation of the progression of human breast cancer. Mouse mammary tissue can give rise to several characteristic types of premalignant hyperplasia and tumor, originating in a duct or acinus, that progress to carcinoma. Three specific types of mouse mammary lesion with premalignant potential have been identified: hyperplastic alveolar nodule (HAN), plaque (PLQ), and ductal hyperplasia (DH). These lesions partially resemble human precursor lesions, and clarification of similarities and differences between the human and mouse lesions could improve our understanding of human breast carcinogenesis. Some invasive breast carcinomas acquire metastatic potential and may cause the death of the patient. Because the most malignant aspect of neoplasia is metastasis, recognition of metastatic phenotypes is particularly important. Mouse mammary carcinomas rarely metastasize, but there exist mouse models of metastasis of mammary carcinoma. In the present review article, we describe morphological, biological, and molecular aspects of premalignant lesions of mice, and we discuss their metastatic phenotypes.

Abstract
BACKGROUND The purpose of the study was to determine the risk of ipsilateral breast carcinoma recurrence (IBCR) and contralateral breast carcinoma (CBC) development in patients with a concurrent diagnosis of ductal carcinoma in situ (DCIS) with atypical ductal hyperplasia (ADH), atypical lobular hyperplasia (ALH), or lobular carcinoma in situ (LCIS). METHODS Records of all 307 patients with DCIS treated with breast-conserving treatment (BCT) from 1968 to 1998 were analyzed. Initial pathology reports and all slides available were re-reviewed for evidence of ADH, ALH, or LCIS. Actuarial local recurrence rates were calculated. RESULTS Fifty-five cases of DCIS were associated with ADH, 11 with ALH or LCIS, and 14 with both ADH and ALH or LCIS. Overall, IBCR occurred in 14% and no significant difference in the IBCR rate was identified for patients with proliferative lesions compared with patients without these lesions (P = 0.38). Development of CBC in patients with concurrent DCIS and ADH was 4.4 times (95% confidence interval [CI], 1.44-13.63) that in patients with DCIS alone (P < 0.01). The 15-year cumulative rate of CBC development was 22.7% in patients with ALH or LCIS compared with 6.5% in patients without these lesions (P = 0.30) and 19% in patients with ADH compared with 4.1% in patients with DCIS alone (P < 0.01). CONCLUSION The risk of CBC development is higher with concurrent ADH than in patients with DCIS alone, and these patients may therefore be appropriate candidates for additional chemoprevention strategies. Concurrent ADH, ALH, or LCIS with DCIS is not a contraindication to BCT.

Abstract
The incidence of lobular cancers in situ is increasing, especially in post-menopausal women. Whereas this form of disease was regarded for a long time as nothing but a risk factor of the occurrence of later infiltrating carcinoma, it now tends to represent a precancerous state whose progression to subsequent infiltrating carcinoma does not inevitably occur. The clinical and radiological diagnosis remains difficult and the choice of therapies varies according to teams, ranging from mere surveillance to mastectomy.

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
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
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
BACKGROUND Ductal carcinoma in situ (DCIS) of the breast encompasses a heterogeneous group of noninvasive cancers that now represents 19% of new breast cancer cases. Optimal treatment remains controversial. We undertook this study to characterize the relationship between angiogenic markers and the biologic behavior of various DCIS phenotypes. METHODS We performed histopathologic review and immunohistochemistry for p53, vascular endothelial growth factor (VEGF), and factor VIII-related antigen on 103 specimens of pure DCIS. RESULTS VEGF expression was seen in 89 tumors (86%) and correlated with microvessel density (MVD). Among VEGF-negative tumors, mean MVD (number of microvessels per square millimeter) was 48 +/- 19, versus 117 +/- 7 for tumors expressing VEGF (P =.001). Strong p53 expression was observed in 28 tumors (27%) and was associated with comedo histology, high tumor grade, necrosis, high MVD, and ipsilateral tumor recurrence (all P < or =.03). Among 8 patients with ipsilateral recurrence, 5 (63%) had tumors with strong p53 expression, whereas only 24% of patients without recurrence had tumors with strong p53 expression (P =.03). Although 7 of 8 patients with ipsilateral recurrence had tumors with VEGF and high MVD, neither parameter achieved statistical significance. CONCLUSIONS These data suggest that molecular alterations may help predict the biologic aggressiveness of DCIS. Mutant p53 expression predisposes the patient toward ipsilateral recurrence, perhaps by promoting angiogenesis. Further investigation may identify clinically useful markers and novel treatment strategies.

Abstract
Intratracheal instillations of 7H-dibenzo(c, g)carbazole (DBC), a tobacco smoke component, into Syrian golden hamsters, resulted in preneoplastic lesions and benign and malignant respiratory neoplasms. Neoplastic progression was associated with specific changes in the extracellular matrix (ECM), dependent on the stage of tumor development. DBC-induced tracheobronchial squamous metaplasia was associated with an increase in collagen type I and type III deposition in the subepithelial ECM, as observed by computer-assisted image analysis of immunohistochemical staining for the aminoterminal propeptides of collagen type I (PINP) and collagen type III (PIIINP). Increased collagen matrix synthesis was detected in dysplasia by in situ hybridization of alpha1(I) mRNA for collagen I and alpha1(III) mRNA for collagen type III after continued exposure to DBC. In well-differentiated squamous cell carcinomas with an expansive growth pattern, collagen deposition increased, as did fiber size. In moderately differentiated neoplasms, basement membrane (BM) destruction and invasion was associated with a destructive growth pattern and decreases in collagen synthesis and the deposition of new collagen. Preserved deposition of mature collagen was detected by staining for the telopeptide of collagen type I propeptide. In less differentiated tumors, ECM development was minimal, with few and small fibers, possibly explaining the rapid development of these neoplasms. Transforming growth factor beta (TGFbeta1) immunoreactivity was increased in hyperplastic epithelium and well differentiated neoplasms and decreased in dysplasia and less differentiated squamous cell carcinomas, while TGFbeta2 and TGFbeta3 expression was also distinct in neoplastic cells. Collagen synthesis and epithelial differentiation were associated with an increased number of myofibroblasts in the ECM and with increased TGFbeta3 immunoreactivity in differentiated cells and in the matrix. The nature of the composition of the ECM was related to neoplastic growth and progression when analyzed by computer-associated image analysis, revealing alterations in collagen structure, size, and shape.

Abstract
OBJECTIVE Up to now, the mechanisms responsible for progression from noninvasive to invasive breast cancer have remained obscure. Tenascin is an extracellular matrix glycoprotein, present in embryonal and fetal tissues, which is also found in the stroma of various benign and malignant pathologies. We studied the expression and immunohistochemical behavior of tenascin in specimens of invasive and preinvasive breast cancer in order to assess its potential role as a marker for tumor invasion. MATERIALS AND METHODS Sixty-eight specimens including 29 noninvasive ductal cancers, 12 invasive ductal cancers, 5 adenoses, 7 fibroadenomas, and 15 samples of normal human breast tissue were evaluated. An immunofluorescent microscopic technique was used for analysis of the localization and distribution of tenascin. Paraffin-embedded biopsies were incubated with primary monoclonal anti-tenascin antibodies (1:25, Dako-tenascin, TN2). Subsequently, trimethylrhodamine-isothiocyanate-conjugated secondary antibodies (rabbit anti-mouse immunglobulins (Dakopatts, Denmark) were added to visualize the protein. RESULTS A significant tenascin expression was observed around the ducts in all samples of patients with preinvasive breast cancers. Intensive staining was also found in the periductal stroma of all specimens of patients with invasive breast cancers. Benign breast lesions showed weaker reactivity. No tenascin expression was detectable in normal human breasts, while tissue samples of in situ cancers presented variable staining intensities positively correlating with the degree of differentiation. CONCLUSION Tenascin immunofluorescence may prove a suitable and helpful adjunct for diagnosing malignant disease and for predicting the invasive potential of premalignant breast lesions.

Abstract
Lobular carcinoma in situ and atypical lobular hyperplasia were first described over 50 years ago. Despite this long incubation period, the biological nature of the lesions remains controversial. They are generally regarded as 'risk indicators' of invasive cancer rather than true precursor lesions. When first described, the 'carcinoma in situ' designation implied radical treatment in the form of a mastectomy. Subsequent observation has shown that the lesions are often multifocal and bilateral. The risk to the woman of developing invasive cancer after a diagnosis of lobular carcinoma in situ is small. Hence, the lesion has increasingly been regarded as a 'hyperplastic' proliferation, which although predicting for subsequent risk of invasive cancer, does not in itself need treatment. In this review, we challenge this view and explore the developments in the understanding of this controversial entity.

Abstract
An image analysis strategy was designed to objectively determine distribution patterns of cell types in spleen sections. The strategy was applied to rat spleen cryostat sections that were strained immunohistochemically by means of monoclonal antibodies against different populations of lymphocytes and macrophages. The strategy revealed three segments of the spleen beginning in the middle of a central arteriole and ending within the red pulp. In each of these segments, three consecutive zones were established: the white pulp, the marginal zone, and the red pulp. In each tissue section, three segments were selected starting in two different arterioles. Consequently, six segments were analysed in each section. Special software was used to calculate percentages of positive staining in all zones in each segment. Image analysis data for each monoclonal antibody tested correlated closely with microscopical observations. The proposed strategy allows objective quantification of lymphocyte and macrophage populations and their distribution patterns. It is an useful tool for studying imbalances in cell populations in the spleen due to immune challenges.

Abstract
Biological markers associated with in situ carcinoma and atypical intraductal hyperplasia in the breast are examined to help in identifying a subgroup of premalignant lesions whose natural history may be influenced by epigenetic factors. The biomarkers may be used as indices in clinical trials aiming to assess the effect of weight reduction, dietary intervention or hormone replacement therapy on the risk of progression to invasive breast cancer. In the current state of knowledge, the expression of oestrogen receptors, p53, bcl-2 and HER-2 neu oncogenes and the Ki-67 index of proliferative activity, are the most useful biomarkers for this purpose. In situ carcinoma of the breast manifests a variety of morphological phenotypes with specific biological characteristics. There is evidence that only a proportion of premalignant lesions are committed to progression to invasive cancer while other lesions undergo spontaneous regression at the time of the menopause. Cross-cultural studies suggest that it is the late-stage epigenetic promoting factors which are responsible for the high incidence of postmenopausal breast cancer in Western women. Obesity in middle life and the Western diet favour the development of hyperinsulinaemic insulin resistance, and the metabolic-endocrine effects of its concomitants may promote mammary carcinogenesis around the time of the menopause and increase the incidence of invasive cancer after the menopause. Because biomarker changes in premalignant lesions are nearer in time to these promoting influences, they could provide intermediate endpoints for testing the hypothesis.
