Abstract
Ductal carcinoma in situ (DCIS) of the breast is a nonobligate precursor of invasive breast cancer, accounting for 20 % of screen-detected breast cancers. Little is known about the natural progression of DCIS because most patients undergo surgery upon diagnosis. Many DCIS patients are likely being overtreated, as it is believed that only around 50 % of DCIS will progress to invasive carcinoma. Robust prognostic markers for progression to invasive carcinoma are lacking. In the past, studies have investigated women who developed a recurrence after breast-conserving surgery (BCS) and compared them with those who did not. However, where there is no recurrence, the patient has probably been adequately treated. The present narrative review advocates a new research strategy, wherein only those patients with a recurrence are studied. Approximately half of the recurrences are invasive cancers, and half are DCIS. So-called "recurrences" are probably most often the result of residual disease. The new approach allows us to ask: why did some residual DCIS evolve to invasive cancers and others not? This novel strategy compares the group of patients that developed in situ recurrence with the group of patients that developed invasive recurrence after BCS. The differences between these groups could then be used to develop a robust risk stratification tool. This tool should estimate the risk of synchronous and metachronous invasive carcinoma when DCIS is diagnosed in a biopsy. Identification of DCIS patients at low risk for developing invasive carcinoma will individualize future therapy and prevent overtreatment.

Abstract
Eighty-five lesions of pure, noninvasive intraductal carcinoma were analyzed by histologic subtypes. The comedo subtype, defined by a solid growth pattern, high nuclear grade, and central necrosis, accounted for only seven lesions (8.2%). Solid, micropapillary, or cribriform patterns with central necrosis comprised 16 cases (18.8%), micropapillary 19 (22.4%), and cribriform 22 (25.9%). The comedo subtype showed several features different from the other subtypes. They occurred in younger patients and had higher numbers of duct profiles with carcinoma and larger tumor diameters. The intensities of lobular cancerization and periductal stromal chronic inflammation were also marked in the comedo lesions. Two of three comedo lesions examined by flow cytometry showed aneuploidy. Three of five tumors with nipple involvement contained at least some comedo-type duct profiles. These findings indicate greater potential aggressiveness of the comedo subtype. In contrast, the micropapillary and cribriform subtypes had fewer involved duct profiles, lower nuclear grade, and less mitotic activity. Microcalcification identified histologically, multifocality, and multicentricity were present in 54.1, 74.1, and 13.8%, respectively, of all lesions examined, and there were no differences between subtypes. Thus, the operative treatment of the comedo subtype (based on spread of disease within the breast) may not need to be more extensive than for other types of intraductal carcinoma. Central necrosis may prove to be of considerably less importance than nuclear grade in future evaluations of intraductal carcinoma.

Abstract
Since the concept of gene profile-based intrinsic subtypes was proposed, various studies on pathological characteristics have been performed. Particularly, triplenegative (TN) breast cancer, which is negative for all hormone receptors [estrogen receptor (ER) and/or progesterone receptor (PgR) and human epidermal growth factor 2 (HER2)], has been attracting attention because effects of endocrine and targeting therapies cannot be anticipated and thus selecting a treatment method is difficult. TN cancer accounts for about 10%-15% of all invasive breast cancer cases in Japanese, which is significantly lower than the incidence reported in the United States. Cytokeratin (CK) 5/6 or epidermal growth factor receptor (EGFR) is positive in 80%, being classified as basal-like carcinoma, but it should be understood that TN breast cancer and basal-like carcinoma are not necessarily the same. Criteria for positivity judgment of ER, PgR, and HER2 were established to select treatment in cases positive for each marker, and greater importance is attached to strict accuracy control. Inversely, the level of negative findings to judge TN varies among the judgment criteria. In any case, the prognosis of TN breast cancer is poor. Pathologically, TN breast cancer shows certain morphological characteristics, such as high grade and a pushing margin, and abnormalities of BRCA1 and p53 are frequently noted. At present, as no effective therapeutic strategy has been established for TN breast cancer, further clarification of the molecular biological characteristics of such cancers is needed. In addition, the incidence of TN-type ductal carcinoma in situ (DCIS) is low, suggesting that TN does not remain preinvasive DCIS for a prolonged period and that it transforms to invasive cancer in an early stage. Because mammary gland basal cells have characters of progenitor or stem cells that differentiate into both luminal epithelium and myoepithelial cells, these cells may be utilized for the differential diagnosis of the benignity or malignancy of intraductal lesions in routine pathological practice. As proliferation markers, such as Ki-67, and multiple gene arrays for gene signature are also utilized to select adjuvant therapy, analysis may progress further in the future.

Abstract
Na(+)/H(+) exchanger regulatory factor 1 (NHERF1) is a postsynaptic density 95/disc-large/zona occludens (PDZ) domain-containing protein that recruits membrane receptors/transporters and cytoplasmic signaling proteins into functional complexes. NHERF1 expression has been demonstrated to be altered in breast cancer, but its role in mammary cancerogenesis and progression remains still undefined. In this paper, we review what is known on the pathological role and the potential clinical application of NHERF1 protein in breast cancer. Recent evidence shows that an increased cytoplasmic expression of NHERF1 suggests a key role of its localization/compartmentalization in defining cancerogenesis, progression, and invasion. NHERF1 overexpression is associated with increasing tumor cytohistological grade, aggressive clinical behavior, unfavorable prognosis, and increased tumor hypoxia. Moreover, NHERF1 co-localizes with the oncogenic receptor HER2/neu in HER2/neu-overexpressing carcinoma and in distant metastases. These data make NHERF1 also a potential candidate of clinical relevance for anti-HER2/neu therapy.

Abstract
It has been reported that pure ductal carcinoma in situ of the breast has morphologic differences from the in situ component of the invasive ductal carcinoma, as well estrogen and progesterone receptors expression according to their cytokeratin expression. However, there is no data comparing other tumor markers without using the cytokeratin expression. The objective of this study is to compare the expression of estrogen receptor (ER) and progesterone receptor (PR), HER-2/neu, p53, and Ki67 between pure ductal in situ carcinoma (pDCIS) and the in situ component of the invasive ductal carcinoma (DCIS + IDC) of the breast, and the in situ component to the invasive component of the same tumor (DCIS + IDC). The immunohistochemistry expression of the tumor markers was performed in 45 cases of pDCIS and DCIS + IDC, yielding a total of 90 cases. Statistical analysis was carried out using Fisher exact test, having a P < 0.05, and Kappa index (kappa) to assess intratumoral concordance. In DCIS + IDC, the in situ and invasive components did not show a significant difference and Kappa index (kappa) was high (0.7-1) for positive and negative expression. ER and PR were significantly different between the pDCIS and DCIS + IDC (ER: 86.7 vs. 66.7% P = 0.04; PR: 80% vs. 55.6% P = 0.02). These findings suggest that in situ component of DCIS + IDC and pDCIS are distinct conditions.

Abstract
BACKGROUND Ductal carcinoma in situ (DCIS) often accompanies invasive breast cancer. The prognostic implication of this is unclear. We sought to determine whether concomitant DCIS affects outcomes in patients with invasive disease. METHODS A nested cohort study was performed of 1,709 invasive breast cancer patients. Clinicopathologic data, along with survival and recurrence data, were collected prospectively. RESULTS Concomitant DCIS was noted in 434 (25.4%) patients. Median follow-up was 59 months. On univariate analysis, the presence of DCIS was associated with a trend toward improved 5-year disease-free survival (93.6% vs 90.5%; P = .089) and overall survival (95.3% vs 92.6%; P = .058). Further, DCIS was associated with younger patient age (median 65 vs 68 years; P < .0001), smaller tumor size (median 1.37 vs 1.44 cm; P = .069), fewer palpable tumors (27.4% vs 33.3%; P = .051), more high-grade tumors (19.1% vs 15.8%; P = .045), and invasive ductal histology (90.6% vs 79.0%; P < .0001). On multivariate analysis, DCIS was not, however, an independent predictor of improved disease-free (odds ratio [OR], 0.715; P = .217) or overall survival (OR, 0.770; P = .251). CONCLUSION Although the presence of DCIS is often associated with favorable features, it is not an independent predictor of improved outcome in patients with concomitant invasive breast cancer.

Abstract
PURPOSE Intratumoral estradiol levels in postmenopausal women with breast cancer are thought to be mainly regulated by the aromatase-mediated conversion from androgens and estrogen sulfotransferase (EST)-mediated reduction of bioavailability. While in invasive breast cancer (IBC) the role of both enzymes has been extensively studied and has led to the use of aromatase inhibitors as a key therapeutic strategy, comparably little is still known about their role in the local regulation of estradiol in ductal carcinoma in situ (DCIS). METHODS We have performed immunohistochemistry to investigate the expression of aromatase and sulfotransferase in custom-made breast cancer tissue arrays containing 96 samples of pure DCIS and in 104 tumor biopsies which contain both, DCIS and invasive components. RESULTS We found that aromatase was equally detectable in epithelial components of both, DCIS and IBC (P = 0.884, Chi square test). However, stromal aromatase expression was significantly higher in IBC compared to adjacent DCIS components (P = 0.034, Chi square test). Whereas no significant difference was observed for epithelial aromatase expression in high versus non-high grade DCIS (P = 0.735 Chi square test), epithelial EST levels were found to be significantly down-regulated in high-grade DCIS compared to non-high grade cases (P = 0.042). CONCLUSION We have demonstrated the presence of both aromatase and EST in malignant epithelium and adjacent stromal fibroblasts in DCIS. Lower stromal aromatase expression in preinvasive breast cancer and lower EST levels in high-grade DCIS suggest that the net effect of intratumoral estradiol (E2)-modulating enzymes results in lower local E2 levels in earlier stages of breast tumorigenesis.

Abstract
AIM To determine the HER2 status of ductal carcinoma in situ (DCIS) and invasive ductal carcinoma (IDC) of the breast. The increased prevalence of HER2 amplification and overexpression in DCIS is considered to be maintained in the intraductal component of IDC; however, HER2 amplification and overexpression are detected much less in IDC. METHODS AND RESULTS Fluorescence in situ hybridization (FISH) and immunohistochemistry (IHC) were performed to detect HER2 in 270 IDCs with an intraductal component and in 50 pure DCIS samples; IHC was also performed in 116 metastatic nodes. HER2 was found to be amplified in 77 cases (28.5%) and overexpressed in 79 (29.3%) of the 270 IDCs. HER2 amplification was similar between intraductal and invasive components of the same tumour. The concordance for HER2 status between invasive and intraductal components of individual tumours was 98.5% and 99.3% by FISH and IHC, respectively. HER2 was amplified in 25 (50%) of the 50 pure DCIS samples. HER2 overexpression in metastatic nodes resembled the HER2 status in the primary tumour for 108 (93.1%) of 116 cases (kappa =0.831). CONCLUSION Our study indicates that the intraductal component of IDC may differ biologically when compared with pure DCIS. HER2 appears to lack a critical role in the progression from DCIS to IDC and HER2 status is maintained in metastatic lesions.

Abstract
In a prospective study using mammographically guided fine needle aspirates in 100 nonpalpable breast lesions, the author's group assessed the reliability of a cytological grading system to define the cytological features of proliferative and nonproliferative breast disease and to differentiate between benign, premalignant and malignant breast lesions. We developed a cytological grading system evaluating the aspirates for the cellular arrangement, the degrees of cellular pleomorphism and anisonucleosis, presence of myoepithelial cells and nucleoli and the status of the chromatin pattern. This grading system, now recognized as the Masood Cytology Index, is commonly used as a surrogate end point biomarker in chemoprevention trials.

Abstract
AIMS Comedo carcinoma is generally regarded as the subtype of ductal carcinoma in situ (DCIS) most likely to progress to invasive carcinoma. Increased angiogenesis could be associated with an enhanced risk of progression and might therefore be a marker of poor prognosis, as can be demonstrated for invasive breast tumours. Therefore, the present study investigates the correlations between the expression of oncoproteins (HER2, HER1/EGFR), angiogenic growth factors (VEGF and PD-ECGF/TP) and microvessel density (MVD) in DCIS. METHODS AND RESULTS Forty-six breast cancer specimens of DCIS were tested immunohistochemically for the expression of angiogenic factors and oncoproteins. Different vascular distribution patterns of DCIS were examined semiquantitatively. Our results showed a significantly inverse correlation between HER1/EGFR and comedo-type DCIS (P = 0.048), but HER1/EGFR expression seemed to be independent of HER2 overexpression. VEGF expression was significantly associated with endoglin expression (P = 0.031) and the cuffing phenomenon (P = 0.017). CONCLUSIONS The significantly inverse correlation between HER1/EGFR and comedo-type DCIS and the observation that VEGF and the other angiogenic factors tested are independent of HER2 overexpression, suggest that progression of comedo-type DCIS and angiogenesis in breast carcinoma are not regulated via the HER1/EGFR or HER2 pathway.

Abstract
An important predictive factor for local recurrence after breast-conserving therapy is the state of the surgical margin. In order to obtain a negative surgical margin, the present case-control study was conducted to determine whether the extent of ductal spread can be estimated from the information obtained by fine-needle aspiration (FNA). Samples from 69 cases of extensive ductal spread (EDS) in which it was thought that cancer cells had remained in the residual breast when the lumpectomy was performed with 2 cm margins, were retrieved and compared with 62 cases having almost the same clinical and pathological tumor size. The cases of EDS included a significantly larger number of papillotubular carcinomas (37%vs 13%, P = 0.004) and displayed a high nuclear atypia (42%vs 26%, P = 0.001). We could estimate the same tendency with cytological studies. Cancer cells with cohesive papillary-like clusters suggesting papillotubular carcinoma and with a large nuclear diameter were significantly more numerous in cases of EDS (P < 0.01). In conclusion, EDS can be determined by estimating histological type via cytodiagnosis and measuring the nuclear diameter of cancer cells.

Abstract
The incidence of ductal carcinoma in situ (DCIS) of the breast has increased significantly in Japanese women. It comprises 14.1% (172/1216) of all primary breast cancers at our institute, and nowadays this histological type is familiar to the surgeons and pathologists of any institute. Several subclassifications have been published recently. Most based on nuclear atypia and the presence of comedonecrosis, and sometimes on the structures of the involved glands. These classifications are correlated with the biological behavior, tumor extent and the risk for local recurrences. The diagnostic accuracy of minimally invasive procedures (aspiration biopsy cytology/core needle biopsy) may differ between subclasses. Atypical ductal hyperplasia (ADH) and microinvasive ductal carcinomas are lesions which resemble but deviate from the DCIS spectrum. The incidence of ADH seems to be lower than in Western countries. Patients with ADH may have a risk for subsequent breast cancer, because ADH is frequently associated with contralateral breast carcinomas. Microinvasion should be treated with caution, but we could not find any metastatic foci in microinvasive ductal carcinomas (T1mic). Tentatively, ADH may be treated similarly to non-comedo (low-grade) DCIS cases, according to our limited clinical experience.

Abstract
BACKGROUND Studies of patients with ductal carcinoma in situ (DCIS) "treated" by diagnostic biopsy alone have been rare, but provide important opportunities to gain insights into the natural history of these lesions. METHODS During a review of 1877 breast biopsy specimens in a nested case-control study of benign breast disease and breast carcinoma risk, the authors identified 13 biopsy specimens with DCIS that were originally diagnosed as benign. Because each of these women was initially given a benign diagnosis, they received no treatment beyond the diagnostic biopsy. RESULTS When compared with women with nonproliferative lesions, the odds ratio (OR) for the development of invasive breast carcinoma among those with retrospectively identified DCIS (n = 6) was 13.5 (95% confidence interval [CI], 3.7-49.7). The OR for the development of any subsequent invasive or in situ breast carcinoma event (n = 10) was 20.1 (95% CI, 6.1-66. 5). A retrospective review of these DCIS biopsy specimens revealed that the nuclear grade was low in four lesions, intermediate in six, and high in three. None showed comedo-type necrosis. Invasive carcinomas developed among women with DCIS of all nuclear grades. All 10 breast carcinoma events (100%) were in the ipsilateral breast. CONCLUSIONS These results provided further evidence that patients with DCIS who received no treatment beyond a diagnostic biopsy were at substantially increased risk for developing ipsilateral invasive breast carcinoma, and that the increased risk in this setting was seen in DCIS of low, intermediate, and high nuclear grades.

Abstract
The number of available breast cancer cell (BCC) lines is small, and only a very few of them have been extensively studied. Whether they are representative of the tumours from which they originated remains a matter of debate. Whether their diversity mirrors the well-known inter-tumoural heterogeneity is another essential question. While numerous similarities have long been found between cell lines and tumours, recent technical advances, including the use of micro-arrays and comparative genetic analysis, have brought new data to the discussion. This paper presents most of the BCC lines that have been described in some detail to date. It evaluates the accuracy of the few of them widely used (MCF-7, T-47D, BT-474, SK-BR-3, MDA-MB-231, Hs578T) as tumour models. It is concluded that BCC lines are likely to reflect, to a large extent, the features of cancer cells in vivo. The importance of oestrogen receptor-alpha (gene ESR1 ) and Her-2/ neu ( ERBB2 ) as classifiers for cell lines and tumours is underlined. The recourse to a larger set of cell lines is suggested since the exact origin of some of the widely used lines remains ambiguous. Investigations on additional specific lines are expected to improve our knowledge of BCC and of the dialogue that these maintain with their surrounding normal cells in vivo.

Abstract
DCIS is a heterogeneous disease whose natural history is poorly defined. Screening mammography has increased the detection rate of DCIS, but we remain unable to identify cases of DCIS that will not progress to invasive carcinoma during an individual's lifetime. Genomics holds great promise in this regard, but prospective studies with long-term follow-up will be needed before concluding that a subset of DCIS is clinically insignificant. The varying intensity of treatment options for DCIS, ranging from mastectomy to excision, RT, and tamoxifen to excision alone, reflects the uncertainty about the natural history of DCIS as well as differing physician values regarding the impact of local recurrence. The extent of DCIS within the breast is the major determinant of whether the patient is a candidate for a breast-conserving approach, and contraindications to the use of breast conservation treatment and to the use of irradiation have been defined. The clinical decision-making process in DCIS would benefit greatly from improvements in our ability to convey information about the long-term risks and benefits of therapy, as well as the tradeoffs in health-related quality of life, to patients, and to incorporate their preferences into the decision-making process.

Abstract
Microinvasive ductal carcinoma of the breast, namely ductal carcinoma in situ with microinvasion (T1mic) as defined by the American Joint Committee on Cancer (AJCC) Staging Manual, is a rare disease, although it is increasing because of widespread use of mammography. The aim of the present study was to describe the clinicopathological and immunohistochemical features of this entity. Twenty-eight patients who were diagnosed as T1mic from January 1997 to August 2002 were studied by using 3-5 mm-thick serial sections with hematoxylin-eosin staining. Immunohistochemical staining for the estrogen receptor (ER), progesterone receptor (PR), p53, Ki-67, and HER-2 were performed. All 28 patients were female, with a mean age of 48.8 years. Twenty-six patients (93%) revealed mammographic abnormalities on routine examination. All foci of the invasions were measured using an ocular micrometer. Invasive foci consisted of isolated cells or cell clusters, or appeared as a tongue-like projection of tumor through the basement membrane of the duct of ductal carcinoma in situ (DCIS). The mean number of invasive foci was 3, and the mean size was 0.6 mm. We found that high nuclear grade and predominant comedo subtype of DCIS components were 57.1% and 46.4%, respectively. Twenty-four cases (86%) demonstrated necrosis of DCIS components. Microinvasion was often associated with periductal stromal reaction (71.5%) and/or a lymphocytic infiltration (78.6%). All patients, excluding two, received axillary resection (the mean number of lymph nodes examined per case was 12), and none had lymph node metastasis. The positive expression of ER and PR strongly related to low grade nuclei and non-comedo subtype; however, the positive expression of HER-2 and P53 related to high grade nuclei and comedo subtype (P<0.01). Ki-67 expression was significantly higher in the high grade nuclei group than in the low grade group (P<0.01). Our study suggested that high nuclear grade and comedo DCIS were more aggressive and more common with microinvasion, and that microinvasion is more likely to be multifocal.

Abstract
With the increasing incidence of ductal carcinoma in situ (DCIS) of the breast and its relationship to invasive breast carcinoma, it is important to understand the biology of this entity. We report on a hospital-based survey of 219 case subjects with DCIS of the breast without associated invasive carcinoma diagnosed between 1982 and 1994. The cases of DCIS were analyzed for architectural type, size, nuclear grade, necrosis, calcification, periductal fibrosis, neovascularization, estrogen receptor (ER), progesterone receptor (PR), and HER-2/neu expression. Periductal neovascularization was associated with tumor size, microcalcifications, periductal fibrosis, and HER-2/neu overexpression. Expression of ER and PR was observed in 60 and 62% of the cases, respectively, and HER-2/neu overexpression in 28% of the cases. ER and PR expression were both inversely associated with comedo histology and nuclear grade. HER-2/neu overexpression was positively associated with comedo histology, high nuclear grade, and periductal neovascularization and was inversely correlated with both ER and PR expression. High nuclear grade was positively associated with comedocarcinoma, necrosis, microcalcification, and periductal fibrosis. The role of these molecular/pathologic markers in the biology of DCIS and their potential clinical implications are discussed.

Abstract
Two possible pathways of breast tumor progression were investigated by searching for values of transition rates that could reproduce the clinically observed co-occurrence frequencies of grades of ductal carcinoma in situ and grades of invasive ductal carcinoma in heterogeneous tumors. Two different pathways were analysed, a linear pathway with seven parameters, and a nonlinear pathway with three parameters. In each pathway ductal carcinoma in situ (DCIS) is a progenitor of invasive carcinoma (IDC). In the linear pathway breast tumor progression is along increasing grades: DCIS 1-DCIS 2-DCIS 3-IDC 1-IDC 2-IDC 3. In the nonlinear pathway progression of DCIS and progression of IDC can proceed in parallel steps, and in addition, with transitions from each grade of DCIS to a corresponding grade of IDC. The biological pathways were interpreted mathematically as compartment models with transition rates between stages in an explicit series of coupled differential equations. Two methods were used to search for transition rates that could reproduce the observed co-occurrence frequencies, a limited empirical search and an extensive genetic algorithmic search. Neither search method, with either pathway, could find a combination of transition rates that would reproduce the set of observed co-occurrence frequencies. We conclude that neither the linear pathway, nor the nonlinear pathway considered here, is an adequate description of progression in heterogeneous breast tumors. This quantitative investigation lends support to previous evidence from histopathology and molecular biology that the grades of DCIS and IDC seen together in heterogeneous breast tumors may not be obligate steps in tumor progression.

Abstract
To compare pathologic features of the cancers arising after different types of benign breast disease (BBD), we reviewed the invasive breast cancer slides of 169 women with a previous benign biopsy result. Lesions were categorized previously as nonproliferative, proliferative without atypia, or atypical hyperplasia. Pathologic features of the cancers were evaluated without knowledge of the previous BBD category. Estrogen and progesterone receptor immunohistochemistry was performed on available tissue blocks. The median times between a benign result and cancer were 100, 124, and 92 months for women with nonproliferative lesions, proliferative lesions without atypia, and atypical hyperplasia, respectively. Cancers in the 3 groups did not differ significantly in tumor size, axillary lymph node status, or histologic grade, and there was no significant difference in the distribution of histologic types of breast cancer. Lymphatic vessel invasion, extensive intraductal component, and hormone receptor status did not differ among BBD categories. The pathologic features of breast cancers that develop in women with a previous benign biopsy result do not vary according to the histologic category of the previous BBD.

Abstract
BACKGROUND Young patient age at diagnosis has been reported as a risk factor for recurrence in patients with ductal carcinoma in situ (DCIS) of the breast treated with breast-conserving therapy (BCT). The authors examined pathologic features of DCIS in three different age groups of patients to identify differences that might explain why young patient age at the time of diagnosis is a risk factor for recurrence. METHODS Excised specimens from 177 breasts of 172 patients with DCIS treated with BCT were studied. All slides from all specimens were reviewed. Patients were divided into 3 age groups: those age < 45 years, those ages 45-59 years, and those age >/= 60 years. The histologic features that were quantified included most common and highest nuclear grades, DCIS architectural pattern, amount of central necrosis (quartiles), calcifications, amount of DCIS, and number of terminal duct lobular units (TDLUs) with cancerization of lobules (COL) within 0.42 cm of the margin, margin status, and size and volume of excision specimens. RESULTS Patients age < 45 years at the time of diagnosis more frequently had higher nuclear grade DCIS (highest nuclear Grade 3: 69%, 60%, and 39%; P = 0.003), respectively and central necrosis (72%, 62%, and 44%; P = 0. 01), respectively. Although not statistically significant, younger patients tended to have comedo subtype DCIS more often (31%, 23%, and 19%; P = 0.35), respectively. Younger patients also more often had smaller initial biopsy specimen maximum dimensions (4.3 cm, 5.2 cm, and 5.7 cm; P = 0.004), respectively, with close or positive margins (89%, 61%, and 64%; P = 0.03), and more TDLUs with COL in the 0.42-cm rim of tissue adjacent to the margin (5.2, 3.6, and 1.9; P = 0.23), respectively. No other features including the amount of DCIS when classified as > 50% or > 75% of ducts, calcifications within DCIS ducts, pattern of DCIS involvement, number of slides examined, number of slides with DCIS, and mean number of DCIS ducts near the margin were found to occur more frequently in younger patients. CONCLUSIONS Younger patients with DCIS may have an increased risk of local recurrence when treated with BCT due to smaller initial excision volumes, a greater proportion of high nuclear grade DCIS, and central necrosis.

Abstract
Ninety-eight minimal breast cancers (MBCs) diagnosed between 1975 and 1990, and all originally considered to be invasive were found, on review, to form three groups: (a) 28 predominantly invasive carcinomas < or = 10 mm ('predominant invasive'); (b) 48 predominantly ductal carcinoma in situ (DCIS) lesions with definite foci of invasion each < or = 10 mm ('predominant DCIS'); and (c) 22 DCIS without evidence of invasion ('pure DCIS'). Tumour histology and immunohistochemical expression of Ki-67, c-erbB2, p53, oestrogen receptor (ER), progesterone receptor (PR), and Bcl-2 were compared. The major finding was the contrasting features in the two invasive groups, with significant differences in their extent of invasion (P < 0.0001), tumour grade (P = 0.03), DCIS type (P = 0.008) and in marker expression. In the predominant invasive group, the infiltrative component was usually greater than 5 mm, low-grade and associated with well-differentiated DCIS. Expression of Ki-67, c-erbB2 and p53 was generally low, and that of ER, PR and Bcl-2 high. The predominant DCIS group in contrast had a much smaller, commonly high-grade, invasive component, usually with poorly differentiated DCIS and the reverse pattern of marker expression. Although not significant, survival of patients in the predominant invasive group was slightly better. These findings suggest that invasive MBCs should perhaps be treated as separate entities, in order to aid more appropriate selection of treatment.

Abstract
BACKGROUND The widespread use of diagnostic breast imaging has yielded an increase in the detection of in situ, microinvasive, and small invasive carcinomas and has provided opportunities to study the earliest stages of breast carcinoma development. The authors of this report analyzed the pathobiologic features of 577 minimal breast carcinomas (MBCs), including in situ carcinomas and invasive carcinomas < or =1 cm, according to the definition given by Hartmann in Cancer (1984;53:681-4). METHODS Estrogen and progesterone receptors (ER and PR), proliferation index (PI), and p53 and neu expression were studied by immunohistochemical technique and measured by quantitative image analysis in 99 pure in situ carcinomas (ISCp); in 105 mixed invasive/in situ carcinomas, with a separate analysis of in situ (ISCm) and invasive (ICm) components; and in 373 invasive carcinomas < or =1 cm (IC). Follow-up data were available for 164 invasive carcinomas. RESULTS A progressive increase in the levels of hormone steroid receptors, from the lowest in ISCm to the highest in IC, was observed (ER, P< 0.001; PR, P=0.005). Levels of PI and p53 expression were higher in ISCm than in the other categories (PI, P=0.007; p53, P=0.046). Overexpression of neu was greater in ICm than in IC (P=0.013). Younger women (< or =40 years) with invasive carcinoma had worse biologic profiles, with lower ER (P < 0.001) and higher PI (P=0.021), neu (P=0.008), and p53 (P=0.040). It was demonstrated clinically that PI and neu were the biologic markers with the highest predictive prognostic values in univariate analysis (PI for recurrence, P < 0.015; neu for recurrence and overall survival, P < 0.001 and P < 0.007, respectively) and in multivariate analysis (neu for recurrence and overall survival, P < 0.007 and P < 0.017, respectively). CONCLUSIONS Biologic phenotypes of MBC can be interpreted as reflecting a dimension of neoplastic progression capacity that is independent of tumor size. This study suggests that biologic markers can be integrated with traditional pathologic indicators for accurate staging of patients.

Abstract
The extensive intraductal component (EIC) of primary breast carcinoma is a special spread pattern observed in the breast. Extensive intraductal component may extend diffusely over the entire breast. Therefore, EIC is considered to be an important risk factor for local recurrence in breast-conserving therapy. However, the pathogenesis of EIC remains uncertain. Whether or not the estrogen receptor (ER) has an influence on its biologic behavior has not been fully studied. A consecutive series of 142 breast carcinomas submitted to the pathology department were examined on step gross sections of 5.0 mm thick. Extensive intraductal component was determined and divided into three types. Estrogen receptor was examined using both immunohistochemistry (ER-IHC) and enzyme immunoassay (ER-EIA). Extensive intraductal component was found in 78 of 138 (56.52%) invasive carcinomas including invasive ductal carcinoma with a predominant intraductal component. Estrogen receptor-IHC positivity was 42.96% (61/142) in the invasive breast carcinoma. Estrogen receptor positivity showed no significant difference between EIC-positive and -negative cases, as well as between EIC and invasive main tumor in the EIC-positive cases. But within the EIC-positive group, ER positivity was found to be higher in the peripheral type of EIC-II and EIC-III than in the central type of EIC-I (P < 0.05). Although ER may not play an essential role in the pathogenesis of EIC, it has shown some significance in the development of peripheral type EIC because of its higher presence in the peripheral type of EIC-II and EIC-III than in the central type of EIC-I.

Abstract
The primary tumour grade in 115 patients with infiltrating ductal carcinoma of the breast was compared with the type of the ductal carcinoma in situ (DCIS) component and with the grade of 169 locally recurrent and metastatic lesions. 102 patients had axillary lymph node metastases at the time of primary surgery, 49 had subsequent recurrences and 36 had both. There was concordance of grade between the primary tumour and axillary lymph node metastases and with subsequent locally recurrent and metastatic lesions. The type of the DCIS component was also significantly associated with the grade of the infiltrating component. No evidence of progression of tumour grade between these phases of mammary carcinoma was found.
