Lobo CL, Shetty A, M M, Dubey A, El-Zahaby SA. Non-systemic Approaches for Ductal Carcinoma In Situ: Exploring the Potential of Ultra-flexible Combisomes as a Novel Drug Delivery Strategy-a Review. AAPS PharmSciTech 2023; 24:119. [PMID: 37173545 DOI: 10.1208/s12249-023-02574-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2023] [Accepted: 04/25/2023] [Indexed: 05/15/2023] Open
Abstract
Ductal carcinoma in situ (DCIS) is currently treated through breast-conserving surgery (lumpectomy), radiation therapy, breast-removing surgery (mastectomy), and hormone therapy to prevent further progression into invasive breast cancer and recurrence. Discrepancies concerning the prognosis of DCIS have sparked controversy about adequate treatment. Considering the severe medical and psychological consequences of mastectomy, developing a treatment approach that arrests the progression of DCIS to the invasive stage without affecting the non-cancerous cells is of utmost importance. In the current review, the problems associated with the diagnosis and management of DCIS have been thoroughly discussed. A summary of the route of administration and drug delivery systems to manage DCIS was also provoked. Innovative ultra-flexible combisomes were also proposed for the effective management of DCIS. Prevention is essential in managing the risk of DCIS and reducing the risk of progression to invasive breast cancer. While prevention is vital, it is not always possible to prevent DCIS, and in some cases, treatment may be necessary. Hence, this review recommends that ultra-flexible combisomes administered as a topical gel provide a non-systemic approach for managing DCIS and thus significantly minimize the side effects and costs associated with existing therapies.

Abstract
Multidisciplinary approach of clinical cases in rehabilitations units can be very complex and divers. Method: We present a case of a woman 30 years old, whose oncological histo-ry begins 9 years ago, when the diagnosis of invasive ductal mammary infiltrating ca-nelular carcinoma grade I was made and treated by tumorectomy (lumpectomy). The pa-tient refused oncological treatment at that time and resorted to alternative medicine dur-ing a period of 7 years: diet without sugar and animal products; regular vitamin B17 treatments; almond kernel cure; high-dose intravenous vitamin C treatment for; intrave-nous ozone therapy; apitherapy with bee venom; oral administration of cannabis oil dur-ing the past four years until now; physical therapy. Results: The evolution is marked by the appearance of multiple bone metastatic lesions. The most worst clinical consequence was a hyperalgesic cervicobrachial neuralgia, due to multiple C6-T3 lytic lesions diag-nosed 2 years ago and C7 compression (close to spinal cord injury), situation which had as medical approach two surgeries interventions, radiotherapy and chemotherapy. Con-clusions: The rehabilitation program was adapted to every stage of clinical evolution and was marked by many complications. All the steps were made for functional improvement and for increase the quality of life.

Abstract
Precis Omission of PORT following BCS remains high among rural patients despite evidence that PORT leads to a significant reduction in the risk of local recurrence. Further research is needed to examine the impact of rural residence on treatment choices and develop methods to ensure equitable care among all breast cancer patients. Background Despite national guidelines, debate exists among clinicians regarding the optimal approach to treatment for patients diagnosed with ductal carcinoma in situ (DCIS). While regional variation in practice patterns has been well documented, population‐based information on rural–urban treatment differences is lacking. Methods Data from the SEER Patterns of Care studies were used to identify women diagnosed with histologically confirmed DCIS who underwent cancer‐directed surgery in the years 1991, 1995, 2000, 2005, 2010, and 2015. Adjusted odds ratios (aORs) and 95% confidence intervals (CIs) were estimated using weighted multivariable logistic regression to evaluate cancer‐directed surgery and use of post‐operative radiation therapy (PORT). Results Of the 3337 patients who met inclusion criteria, 27% underwent mastectomy, 26% underwent breast‐conserving surgery (BCS) without PORT, and 47% underwent BCS with PORT. After adjustment for other covariates, there was no difference in the likelihood of receiving mastectomy between rural and urban patients (aOR = 0.65; 95% CI 0.37–1.14). However, rural residents were more likely than urban residents to have mastectomy during 1991/1995 (aOR = 1.78; 95% CI 1.09–2.91; pinteraction = 0.022). Across all diagnosis years, patients residing in rural areas were less likely to receive PORT following BCS compared to urban patients (aOR = 0.35; 95% CI 0.18–0.67). Conclusions Omission of PORT following BCS remains high among rural patients despite evidence that PORT leads to a significant reduction in the risk of local recurrence. Further research is needed to examine the impact of rural residence on treatment choices and develop methods to ensure equitable care among all breast cancer patients.

Abstract
Our aim was to investigate the correlations between the findings of two-dimensional shear-wave elastography (2D-SWE) and the histopathologic results of microcalcifications (MCs) visualized using ultrasonography (USG). Fifty people with suspicious MCs without accompanying mass were evaluated. They underwent USG and 2D-SWE before USG-guided tru-cut biopsy. SWE values and histopathologic features were compared statistically. The variables between groups were analyzed using the Mann-Whitney U test. Receiver operating characteristic analysis was performed and cut-off values determined to discriminate malignancy, invasiveness and high grade. Pathology confirmed 27 malignant lesions (18 invasive ductal carcinomas, one invasive lobular and eight ductal carcinomas in situ) and 23 benign ones. There was a statistically significant difference between the SWE values of malignant and benign MCs (p < 0.001). The diagnostic performance of SWE for malignancy, invasiveness and high grade were as follows, repectively: sensitivity (93%, 83%, 88%), specificity (91%, 88%, 53%), positive predictive value (93%, 94%, 44%), negative predictive value (91%, 70%, 90%) and area under the curve (0.952, 0.885, 0.776). Cut-off values were determined as 57 kPa for malignancy, 124 kPa for invasiveness and 124.5 kPa for high grade. In conclusion, SWE is a useful method in clinical practice for characterizing MCs that can be visualized with USG.

Abstract
Background The purpose of this paper is to clarify the ultrasonographic features and classification of ductal carcinoma in situ (DCIS), and to evaluate the ability of ultrasonography in the prediction of DCIS. Methods The clinical data, gray-scale ultrasound images and pathological results of 219 DCIS lesions that detected in 203 consecutive patients who underwent ultrasonography and surgery in our hospital from January 1, 2014 to December 31, 2019 were collected retrospectively. Ultrasonographic features and classification of DCIS were summarized, and the accuracy of ultrasonography in predicting different ultrasonographic findings of DCIS were compared. Results Among the 219 DCIS lesions, 91 (41.6%) presented as mass-like lesions and 128 (58.4%) were non-mass-like lesions. For the 91 mass-like DCIS lesions, 79 were hypoechoic solid masses, 12 were cystic-solid structures. For the 128 non-mass-like DCIS lesions, 114 were hypoechoic areas, 10 were ductal dilatation accompanied with intraductal solid components, and 4 were multiple punctate echogenic foci only. The diagnostic accuracy of ultrasound for the 219 DCIS lesions was 81.7% (179/219). The diagnostic accuracy of mass-like DCIS lesions was 90.1% (82/91), which was significantly higher than that in non-mass-like DCIS lesions [75.8% (97/128), P=0.007]. The diagnostic accuracy of hypoechoic solid masses was significantly higher than those of the other ultrasonographic findings (P=0.002). Ducts abnormalities were detected in 45 (20.5%) lesions and punctate echogenic foci in 134 (61.2%) lesions. The diagnostic accuracy of lesions with ducts abnormalities was 93.3% (42/45), which was significantly higher than that in lesions without ducts abnormalities [78.7% (137/174), P=0.024]. The diagnostic accuracy of lesions with punctate echogenic foci was 92.5% (124/134), which was significantly higher than that in lesions without punctate echogenic foci [64.7% (55/85), P=0.000]. Conclusions DCIS lesions can effectively be recognized as mass-like lesions and non-mass-like lesions by ultrasound. Hypoechoic areas and hypoechoic solid masses were the most common ultrasonographic features of DCIS. Ducts abnormalities and punctate echogenic foci were helpful for the diagnosis of DCIS.

Abstract
Patients with ductal carcinoma in situ with microinvasion (DCISM) have worse cancer-specific survival, disease-free survival and overall survival, and a higher mortality rate compared with patients with ductal carcinoma in situ (DCIS). Distinguishing DCISM from DCIS via preoperative imaging could help to predict the prognosis of patients. The present study compared the sonographic and mammographic features of patients with DCIS and DCISM. A total of 147 women (94 patients with DCIS and 53 patients with DCISM) were retrospectively included. The sonographic lesions were classified as either masses or non-mass abnormalities. The lesions observed on mammography were classified as calcifications only, mass, asymmetry or architectural distortion. Statistical comparisons were performed using the Mann-Whitney U test, χ2 test, Fisher's exact test and multiple logistic regression analysis. Univariate and multivariate analyses showed that the presence of calcifications (P=0.038) and vascularity (P=0.025) on sonography were associated with DCISM. Furthermore, a lager distribution of calcifications was associated with a higher likelihood of DCISM (P=0.002). In conclusion, the presence of calcifications and vascularity on sonography or a lager distribution of calcifications on mammography may suggest DCISM.

Abstract
Ductal carcinoma in situ (DCIS) is a non-obligate precursor to most types of invasive breast cancer (IBC). Although it is estimated only one third of untreated patients with DCIS will progress to IBC, standard of care for treatment is surgery and radiation. This therapeutic approach combined with a lack of reliable biomarker panels to predict DCIS progression is a major clinical problem. DCIS shares the same molecular subtypes as IBC including estrogen receptor (ER) and progesterone receptor (PR) positive luminal subtypes, which encompass the majority (60-70%) of DCIS. Compared to the established roles of ER and PR in luminal IBC, much less is known about the roles and mechanism of action of estrogen (E2) and progesterone (P4) and their cognate receptors in the development and progression of DCIS. This is an underexplored area of research due in part to a paucity of suitable experimental models of ER+/PR + DCIS. This review summarizes information from clinical and observational studies on steroid hormones as breast cancer risk factors and ER and PR as biomarkers in DCIS. Lastly, we discuss emerging experimental models of ER+/PR+ DCIS.

Abstract
Purpose The purpose of this study was to evaluate the ultrasonographic features of pure ductal carcinoma in situ (DCIS) of the breast and to evaluate the correlations of ultrasonographic features with pathologic and biological features. Methods A total of 141 lesions in 138 women with pure DCIS who underwent preoperative breast ultrasonography were retrospectively reviewed. Ultrasonographic features were analyzed using the American College of Radiology Breast Imaging Reporting and Data System (BI-RADS) ultrasonography lexicon and the diagnostic criteria of the Japan Society of Ultrasonics in Medicine. Pathologic features including the nuclear grade and presence of comedonecrosis were evaluated. Biological markers including estrogen receptor, progesterone receptor, and human epidermal growth factor receptor 2 (HER2) status, as well as the Ki-67 index, were recorded. Ultrasonographic features were compared with pathologic findings and biological markers using the chi-square test. P-values of <0.05 were considered to indicate statistical significance. Results Of the 141 lesions, 75 (53.2%) were mass lesions, 56 (39.7%) were non-mass lesions, and 10 (7.1%) were not visible. The most common feature of the mass pattern was a mass with irregular shape (32.6%), an indistinct margin (27.7%), and hypoechogenicity (37.6%). Microcalcifications were observed in 48 cases (36.6%) as an associated feature. Calcifications outside of a mass were more common than calcifications within a mass. Ultrasonographic microcalcifications and ductal changes were frequently observed in non-mass lesions. Ultrasonographic non-mass lesions were associated with high-grade DCIS (P=0.004) and the presence of comedonecrosis (P=0.006). Microcalcifications were significantly associated with high-grade DCIS (P<0.001), the presence of comedonecrosis (P<0.001), an elevated Ki-67 (P<0.001), and HER2 positivity (P=0.003). Conclusion The most common ultrasonographic feature of pure DCIS was an irregular, hypoechoic mass with an indistinct margin. Ultrasonographic microcalcifications and ductal changes were more frequent in non-mass lesions, which were correlated with poor prognostic factors, such as a high nuclear grade, comedonecrosis, HER2 positivity, and an elevated Ki-67 index.

Abstract
Breast cancer is one of the most prevalent forms of cancer in women. The currently available treatment for breast cancer is mostly curative except when it becomes metastatic. One of the major sites for metastasis of breast cancer is the bone. Homing of the circulating tumor cells is tightly regulated including a number of factors present in the cells and their microenvironment. Runx2, a transcription factor plays an important role in osteogenesis and breast cancer mediated bone metastases. One of the recent advances in molecular therapy includes the discovery of the small, non-coding microRNAs (miRNAs) and they target specific genes to reduce their expression at the post-transcriptional level. This review provides an outline of breast cancer mediated bone metastasis and summarizes the recent development on the regulation of Runx2 expression by miRNAs which can lead to novel molecular therapeutics for the same.

Abstract
Breast cancer screening with mammography is strongly advocated by some and rejected by others. Discussions in the medical literature focus on the beneficial and unfavourable effects of breast cancer screening. Among the latter are the suggested excess mortality rate of screen-detected breast cancer patients, the high number of unnecessary biopsies, the possibility of overdiagnosis and subsequent unnecessary treatment, and the occurrence of interval breast cancer cases. It is concluded that screening can to a certain extent prevent women from dying of breast cancer but some negative effects are unavoidable. However, adequate training of the screening team can minimize the number of unnecessary biopsies and the occurrence of interval cancers. Research is needed to evaluate the natural course of so-called ‘minimal’ lesions, and to optimize screening tests. The search for new (imaging) techniques is needed to detect lobular cancers in dense breasts.

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
OBJECTIVE The objective of our study was to compare the sonographic features of pure ductal carcinoma in situ (DCIS) lesions with the initial clinical presentation and histopathologic findings. MATERIALS AND METHODS The images and records of 691 patients with pure DCIS who underwent preoperative mammography and whole-breast sonography as part of staging workup in a single institution from January 1, 1996, through July 31, 2009, were reviewed. The BI-RADS sonography lexicon was used when reviewing the sonographic studies. Histopathologic features recorded included estrogen receptor (ER) status, nuclear grade, and presence or absence of comedonecrosis. Statistical comparisons were made using the Student t test, chi-square test, Fisher exact test, Kruskal-Wallis or Wilcoxon rank sum test, multiple logistic regression analysis, and Pearson correlation coefficient. RESULTS A total of 304 (44%) tumors were visible on mammography and sonography; 315 (46%), on mammography only; 58 (8%), on sonography only; and 14 (2%), on neither mammography nor sonography. The most common sonographic appearance of DCIS was an irregular hypoechoic mass with indistinct margins and normal posterior features that was indistinguishable from invasive carcinoma. Patients with symptomatic high-nuclear-grade DCIS, dense breasts, and comedonecrosis were younger and had larger tumors on sonography than asymptomatic women with nondense breasts and low-nuclear-grade and noncomedo DCIS. Women with ER-negative DCIS were older and had larger tumors on sonography than women with ER-positive DCIS. ER-negative tumors were more frequently visible on sonography than ER-positive tumors (p=0.007). High-grade DCIS (p<0.0001) and comedo DCIS (p<0.0001) presented more frequently as microcalcifications, architectural distortion, and ductal changes on sonography than low-grade DCIS or noncomedo DCIS. CONCLUSION Of the 691 pure DCIS lesions, 362 (52%) were visible on sonography and presented most commonly as a mass. Lesion visibility of DCIS on sonography was not related to nuclear grade or the presence of comedonecrosis.

Abstract
BACKGROUND Palpable pure DCIS is a rare entity that presents differently than screen-detected DCIS. The aim of this study was to evaluate the clinical, radiological, and pathological characteristics and management of pDCIS in a retrospective cohort of patients. PATIENTS AND METHODS Patients diagnosed with pDCIS from January 1999 to December 2011 were identified from an electronic patient database and were included in this study. RESULTS During this period, 669 cases of DCIS were diagnosed and 62 (9.3%) were pDCIS (mean age, 56.9 ± 15.1 years). The most common finding on ultrasound was mass in 43 patients (75%) and only 18 (33%) cases had calcification on mammography. The lesion was mammographically occult in 20 patients (37%). Ultrasound was more sensitive and delineated the pDCIS in 45 (80%) cases. Mean size of the pDCIS was 36.9 ± 30.4 mm and most were high grade (n = 42; 68%) and associated with comedo necrosis in 36 (59%). Most were oestrogen receptor (ER)-positive (n = 34; 62%), however 21 patients (38%) were ER-negative. Breast conservation was attempted in 30 patients (48%), however, because of involved margins further therapeutic surgery was needed in 10 patients (33%). Axillary surgery (sentinel lymph node biopsy or axillary nodal sampling) was performed in 34 patients (55%) and no lymph node metastasis was identified. During a medial follow-up of 60 months, 1 patient has developed a mastectomy scar recurrence and the rest remain disease-free. CONCLUSION Palpable DCIS is often occult on conventional radiological imaging and is generally associated with aggressive pathological features. Hence, careful individualized surgical planning through a multidisciplinary meeting is necessary for their management.

Abstract
Breast cancer (BC) is traditionally viewed as an oestrogen-dependent disease in which the androgen receptor (AR) is inhibitory, counteracting the oncogenic activity of oestrogen receptor α (ERα (ESR1)). Most probably as a result of this crosstalk, the AR has prognostic value in ER-positive disease, with AR positivity reported to correlate with a better prognosis. Activation of the AR pathway has been previously used as a therapeutic strategy to treat BC, but its usage declined following the introduction of the anti-oestrogen tamoxifen. More recently, it has been demonstrated that a subset of triple-negative BCs (molecular apocrine) are dependent upon androgen signalling for growth and therapies that inhibit androgen signalling, currently used for the treatment of prostate cancer, e.g. the antiandrogen bicalutamide and the CYP17 inhibitor abiraterone acetate are undergoing clinical trials to investigate their efficacy in this BC subtype. This review summarises the current knowledge of AR activity in BC.

Abstract
PURPOSE To investigate the characteristic sonographic (US) findings of pure ductal carcinoma in situ (DCIS) in a large series. METHODS We retrospectively reviewed the US findings of 126 cases of pure DCIS in 123 consecutive patients who underwent surgery for breast cancer in our hospital. We analyzed the US findings of the lesions according to mass or nonmass abnormality, shape, margin, orientation, echogenicity, echotexture, boundary echo, posterior acoustic features, presence of associated ductal dilatation, presence of intralesional cystic focus, and presence of microcalcifications on US. We compared the US characteristics of pure DCIS with and without mammographic microcalcifications. RESULTS Seventy-eight cases of pure DCIS had microcalcifications and 48 had no microcalcifications on mammography (MG). Overall, 109 cases (86.5%) of pure DCIS were demonstrated on US. DCIS with microcalcifications on MG showed positive US findings in 79.5% of cases. The most common US finding was heterogeneous hyper- or isoechoic parenchyma with intralesional microcalcifications and without posterior acoustic features. DCIS without microcalcifications on MG showed positive US findings in 97.9% of cases. The most common US findings were masses with round or oval shape, microlobulated margin, parallel orientation, heterogeneous mild hypoechogenicity, and without boundary echo or posterior acoustic features. Ductal dilatations and intralesional cystic foci were present in 17.5% (22/126) and 23.8% (30/126) of pure DCIS, respectively. CONCLUSIONS Overall, US could demonstrate 85.7% of pure DCIS cases, including 16 (12.7%) cases of clinically and mammographically occult pure DCIS. DCIS with and without microcalcifications on MG showed different US characteristics.

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 For DCIS patients eligible for breast conservation treatment (BCT), it remains unclear whether presenting with physical signs/symptoms (Phys) confers a worse long-term prognosis compared to mammographically detected DCIS (Mam). METHODS We collected data on 669 DCIS patients treated with BCT from 1974 to 2007 of whom 80 were identified as category "Phys" and 589 were in category "Mam." RESULTS Treatment parameters (i.e., the RT dose delivered, boost, rates of stereotactic biopsy, re-excision, node dissection) did not differ significantly between the two cohorts (p = NS). At a 60-month median follow-up, significant associations included younger age at presentation (p < 0.001), non-white race (p = 0.041), larger tumor size (p = 0.002), more 1°/2° papillary histology (1°, p = 0.001; 2°, p = 0.005) for the Phys cohort. As expected, mammograms were more likely to show mass/nodules/asymmetrical densities and less likely to show microcalcifications for the Phys versus Mam group (p < 0.0001). There were no differences in family history, multifocality, grade, necrosis, or residual disease at re-excision, nodal involvement, status of margins, or ER/PR/HER-2 between the cohorts. The local relapse-free survival was similar at 5 years (100 vs. 96.9 %, p = 0.116) and 10 years (96.2 vs. 96.2 %, p = 0.906), with no significant overall survival difference at 10 years (97.5 vs. 95.9 %, p = 0.364) between the Phys and Mam patients, respectively. On multivariate analysis, presentation was not an independent predictor of local relapse-free survival or overall survival when accounting for age, race, tumor size, mammogram appearance, and adjuvant hormone treatment. CONCLUSIONS Our findings suggest that although some clinicopathological differences exist between DCIS patients presenting with physical signs/symptoms compared with those presenting with mammographically detected disease, long-term outcomes are similar for patients appropriately selected for BCT.

Abstract
In this study, we evaluated cytomorphologic features of different subgroups of ductal carcinoma in situ (DCIS); we compared seven cytologic features between DCIS and invasive ductal carcinoma (IDC) aspirates to determine whether diagnosis of stromal invasion can be made based on fine-needle aspiration (FNA) findings. There were 142 cases of DCIS and 1,978 cases of IDC enrolled in our study. FNA analysis revealed 80.3% sensitivity for DCIS and 94.7% sensitivity for IDC. High and intermediate grade DCIS exhibited marked nuclear abnormality (92.1% vs. 35.7%, 30.0%; P1 < 0.001, P2 < 0.001) and necrosis (69.7% vs. 0%, 10.0%; P1 < 0.001, P2 = 0.001) in a higher percentage of cases compared to low grade DCIS and intraductal/intracystic papillary carcinoma. The rates of background macrophages (71.3% for DCIS and 21.9% for IDC, P < 0.001) and extensive necrosis (54.0% for DCIS and 16.7% for IDC, P < 0.001) were significantly higher in DCIS compared to IDC. Lymphocytes were observed in conjunction with tumor cells more frequently in IDC (81.3%) compared to DCIS (36.8%, P < 0.001). Stromal fragments associated with tumor cells were only observed in invasive lesions (11.9% micro-invasive DCIS and 52.1% IDC). Tubular structures were found exclusively in IDC (11.5%). Cytologic criteria for diagnosis of high and low grade DCIS are different. The suspicion of DCIS is raised when background macrophages and extensive necrosis are observed. Stromal invasion is suggested by FNA if lymphocytes are entwined around tumor cells or if stromal fragments associated with tumor cells or tubular structures are observed.

Abstract
RATIONALE AND OBJECTIVES The aim of this study was to describe the mammographic, sonographic, and magnetic resonance imaging (MRI) findings of micropapillary ductal carcinoma in situ. MATERIALS AND METHODS Between May 2004 and April 2008, the pathology database of a single institution was reviewed for patients diagnosed with histologically proven DCIS with a predominant micropapillary component. Clinical data and preoperative imaging studies, including mammography, sonography, and/or MRI, were reviewed. RESULTS Forty-one patients (mean age, 55 years; range, 33-82 years) with 42 tumors were included in this study. Most tumors (n = 32 [76%]) were detected on screening mammography, with a mean tumor size of 4.7 cm (range, 0.5-13 cm). Of 42 tumors, seven (16%) were multicentric, and 23 (54%) were high nuclear grade. Calcifications were identified in 36 tumors (86%) on mammography, most frequently with pleomorphic morphology (15 tumors [42%]). Sonography was frequently normal (17 of 36 [47%]). When abnormal, irregular mass and angular margins were the most common sonographic features. All four tumors with MRI showed non-mass-like enhancement and showed the best correlation with pathologic size. CONCLUSIONS Micropapillary ductal carcinoma in situ is a unique subset of in situ cancer that is frequently clinically occult but has a large mean size at diagnosis and demonstrates highly suspicious features at imaging including pleomorphic calcifications on mammography and an irregular mass at sonography. MRI may be the imaging modality of choice for delineation of disease extent and warrants further validation.

Abstract
BACKGROUND Most ductal carcinoma in situ (DCIS) of the breast is asymptomatic and usually manifests as calcifications in screening mammography. On the other hand, little is known about ultrasonographic (US) features of asymptomatic DCIS, for US is rarely used for the diagnosis and evaluation of DCIS because of low sensitivity in detecting microcalcifications. PURPOSE To evaluate US detection and characterization of DCIS in asymptomatic women and correlate these imaging findings with the histopathologic features. MATERIAL AND METHODS This retrospective study evaluated mammographic and US images of 60 DCIS cases from 59 asymptomatic women. US was performed in knowledge of mammographic findings. The following histopathologic parameters were analyzed: Van Nuys classification, architectural pattern, and presence of microinvasion. Image detectability and US features were correlated with these histopathologic parameters. RESULTS Of the 54 cases (90.0%) detected on mammography, 48 cases (88.9%) had microcalcifications only, 5 (9.3%) had microcalcifications with associated density, and 1 (1.9%) had soft tissue density alone. Of the 38 cases (63.3%) identified by US, 29 cases (76.3%) had a mass with or without microcalcifications, six (15.8%) had microcalcifications only, and three (7.9%) had other findings. US identified lesions were associated with higher Van Nuys groups, microinvasion and comedocarcinoma (P = 0.044, P = 0.024, and P = 0.032, respectively). The most common US finding was a not-circumscribed, oval mass with parallel orientation and normal acoustic transmission. Microcalcifications were seen on US in 31 (81.6%) of the 38 US visible cases; this finding showed a trend of association with Van Nuys group 2 and 3 but was not statistically significant (P = 0.063). CONCLUSION When DCIS was identified on US, it was associated with more aggressive histopathologic type. However, mammographic correlation is essential to differentiate benign from malignant lesion in cases seen by US; US findings of asymptomatic DCIS had a low suspicion of malignancy.

Abstract
BACKGROUND Triple negative (TN) breast cancer is characterized as having a high malignancy potential and a poor prognosis. An understanding of the radiological features of TN DCIS will enable the early detection of intractable TN invasive breast cancer. METHODS Our cohort of 494 DCIS patients, including 18 TN DCIS cases (3.6%), was diagnosed and treated between January 2006 and November 2009. We reviewed the TN DCIS cases in order to assess mammogram (MMG), ultrasound (US), magnetic resonance imaging (MRI), and pathology findings. Routine diagnostic MMG, US, and MRI were performed before surgery in our institution. RESULTS The average age of TN DCIS patients was 54.2 years (40-73). MMG findings were as follows: no abnormal findings (n = 4), masses (n = 3), focal asymmetric density (n = 2), architectural distortion (n = 5), and calcifications (n = 4). US findings included low echoic masses (n = 17) and architectural distortion (n = 4). MRI findings (two patients did not undergo this examination) included mass (n = 6) and non-mass-like enhancements (n = 10). The average lesion measured 3.3 cm in diameter (0.5-8.5 cm). The histological findings were non-comedo type (n = 9) and mixed type including some comedo components (n = 9). Notably, our study revealed that only 22% of TN DCIS cases were detected via mammographic abnormal calcifications. This percentage was less than in non-TN DCIS cases. TN DCIS cases were detected mainly because of masses or asymmetry. US and MRI findings of TN DCIS revealed the same features considered to be common DCIS findings. CONCLUSION We diagnosed TN DCIS in 3.6% of our cohort including 494 DCIS patients. Incidences of TN DCIS with mammographic abnormal calcifications were fewer than those of non-TN DCIS cases.

Abstract
Ductal carcinoma in situ (DCIS) refers to breast epithelial cells that have become "cancerous" but still reside in their normal place in the ducts and lobules. In this setting, cancerous means that there is an abnormal increase in the growth of the epithelial cells, which accumulate within and greatly expand the ducts and lobules. DCIS is a nonlethal type of cancer because it stays in its normal place. However, DCIS is very important because it is the immediate precursor of invasive breast cancers, which are potentially lethal. This article provides a general overview of DCIS, including historical perspective, methods of classification, current perspective, and future goals.

Abstract
OBJECTIVE The purpose of this study was to differentiate between high-grade and non-high-grade ductal carcinoma in situ (DCIS) of the breast on sonography. METHODS From October 2003 to August 2009, 76 DCIS lesions in 73 women who underwent sonography and mammography were included in this study. Lesions were confirmed by mastectomy, breast-conserving surgery, or surgical biopsy. Images were analyzed by 2 radiologists with consensus and were correlated with histologic grades. RESULTS Of the 76 lesions, 44 were classified as high--grade and 32 as non-high-grade DCIS. Fifty-seven lesions (75.0%) were identified on sonography, which revealed a mass in 30 cases, microcalcifications in 20, ductal changes in 4, and architectural distortion in 3. All cases with false-negative findings on sonography (n = 19) showed microcalcifications on mammography. On sonography, masses were more frequently found in non-high-grade (62.5%) than high-grade DCIS (22.7%; P < .01). No significant difference was seen in the sonographic features of masses between high-grade and non-high-grade DCIS. Microcalcifications were more common in high-grade (43.2%) than non-high-grade (3.1%) DCIS (P = .02). Most sonographically visible microcalcifications had associated findings such as ductal changes (n = 11), a mass (n = 7), or a hypoechoic area (n = 5). The detection rate of microcalcifications on sonography was higher in high-grade (62.9%) than non-high-grade DCIS (25.0%; P = .023). CONCLUSIONS Microcalcifications with associated ductal changes (11 of 31 [35.5%]) were the most common sonographic findings in high-grade DCIS. An irregular hypoechoic mass with an indistinct and microlobulated margin (13 of 26 [50.0%]) was the most frequent finding in non-high-grade DCIS.

Abstract
BACKGROUND With the increasing use of high-resolution ultrasound (US) examination, many breast carcinomas that cannot be identified by mammography (MMG) alone have been detected. Many of these carcinomas are ductal carcinoma in situ (DCIS) and small-sized invasive carcinomas. Until date, DCISs have often been described as palpable masses with calcifications on MMG, but what are the characteristics of DCISs that are detectable by US alone? METHODS One hundred fifty cases with DCIS that we experienced at our clinic from 2003 to 2007 were classified into 47 cases (echo group) diagnosed by US alone and 103 cases (MMG/PE group) diagnosed by MMG or clinically. RESULTS US findings of the echo group showed cystic or solid lesions in 37 cases (79%). The mean age of the echo group was significantly higher than that of the MMG/PE group (59.6 vs. 51.2 years; P < 0.01). Tumor sizes detected by US were 5.7 + 2.8 and 11.5 + 10.8 mm (P < 0.001), respectively. The tumor sizes of the echo group were, therefore, approximately half that of the MMG/PE group. Extensive intraductal components were significantly fewer in the echo group, and tumor grades of the echo group were significantly low (Van Nuys classification). In the echo group, all cases with a tumor size < 5 mm were grade 1 by Van Nuys classification. In addition, cases with > or = 5 mm tumor size had a significantly lower tumor grade in the echo group than in the MMG/PE group. CONCLUSIONS Cystic or solid lesions accounted for approximately 80% of US findings of DCISs detected by US alone, and most were similar to benign forms. Moreover, most DCISs detected by US alone were localized and of low grade (Van Nuys classification).

Abstract
PURPOSE To assess the feasibility of percutaneous multiprobe breast cryoablation (BC) for diverse presentations of cancers that remained in situ after BC. MATERIALS AND METHODS After breast magnetic resonance (MR) imaging and thorough consultation, patients underwent BC after giving informed consent. This study was approved by the institutional review board. In 12 BC sessions, 22 breast cancer foci (stages I-IV) were treated in 11 patients who refused surgery by using multiple 2.4-mm cryoprobes. Five patients had recurrent disease and six had new diagnoses. With use of only local anesthesia, six patients were treated with ultrasonographic (US) guidance and five were treated with both computed tomographic (CT) and US guidance. Saline injections and warming bags were used to protect the skin. Procedure success was defined as 1 cm visible ice beyond all tumor margins. MR imaging and/or clinical follow-up were available for up to 72 months after BC. RESULTS US produced sufficient ice visualization for small tumors, whereas CT helped confirm overall ice extent. The mean pretreatment breast tumor diameter was 1.7 cm +/- 1.2 (range, 0.5-5.8 cm), and an average of 3.1 cryoprobes produced 100% procedural success with mean ice diameters of 5.1 cm +/- 2.2 (range, 2.0-10.0 cm). No significant complications, retraction, or scarring were noted. Biopsies at the margins of the cryoablation site immediately after BC and at follow-up were all negative. No local recurrences have been noted at an average imaging follow-up of 18 months. CONCLUSIONS In conjunction with thorough pre- and postablation MR imaging, CT/US-guided multiprobe BC safely achieved 1 cm visible ice beyond tumor margins with minimal discomfort, good cosmesis, and no short-term local tumor recurrences.

Abstract
INTRODUCTION Randomized trials indicate that adjuvant radiotherapy plus tamoxifen decrease the five-year risk of recurrence among ductal carcinoma in situ patients treated with breast-conserving surgery from about 20% to 8%. The aims of this study were to examine the use and impact of these therapies on risk of recurrence among ductal carcinoma in situ patients diagnosed and treated in the community setting. METHODS We identified 2,995 patients diagnosed with ductal carcinoma in situ between 1990 and 2001 and treated with breast-conserving surgery at three large health plans. Medical charts were reviewed to confirm diagnosis and treatment and to obtain information on subsequent breast cancers. On a subset of patients, slides from the index ductal carcinoma in situ were reviewed for histopathologic features. Cumulative incidence curves were generated and Cox regression was used to examine changes in five-year risk of recurrence across diagnosis years, with and without adjusting for trends in use of adjuvant therapies. RESULTS Use of radiotherapy increased from 25.8% in 1990-1991 to 61.3% in 2000-2001; tamoxifen increased from 2.3% to 34.4%. A total of 245 patients had a local recurrence within five years of their index ductal carcinoma in situ. The five-year risk of any local recurrence decreased from 14.3% (95% confidence interval 9.8 to 18.7) for patients diagnosed in 1990-1991 to 7.7% (95% confidence interval 5.5 to 9.9) for patients diagnosed in 1998-1999; invasive recurrence decreased from 7.0% (95% confidence interval 3.8 to 10.3) to 3.1% (95% confidence interval 1.7 to 4.6). In Cox models, the association between diagnosis year and risk of recurrence was modestly attenuated after accounting for use of adjuvant therapy. Between 1990-1991 and 2000-2001, the proportion of patients with tumors with high nuclear grade decreased from 46% to 32% (P = 0.03) and those with involved surgical margins dropped from 15% to 0% (P = 0.03). CONCLUSIONS The marked increase in the 1990s in the use of adjuvant therapy for ductal carcinoma in situ patients treated with breast-conserving surgery in the community setting only partially explains the 50% decline in risk of recurrence. Changes in pathology factors have likely also contributed to this decline.

Abstract
OBJECTIVE The purpose of this study was to evaluate imaging findings in noncalcified ductal carcinoma in situ (DCIS) and to compare histologic findings between noncalcified and calcified DCIS. METHODS From January 2005 to May 2008, 195 patients with pathologically confirmed DCIS were recruited. Among these, 36 patients (18%) had noncalcified DCIS. We retrospectively reviewed their imaging findings according to the American College of Radiology Breast Imaging Reporting and Data System. We also reviewed pathologic reports for all patients with DCIS to obtain information on the histologic type, nuclear grade, and biological markers. RESULTS Among the 36 patients with noncalcified DCIS, 21 (58%) were symptomatic. On mammography, 25 patients (69%) showed abnormal findings, and 11 patients showed false-negative findings. On sonography, 29 of 36 patients (81%) showed a mass, whereas the remaining 7 patients (19%) showed nonmass lesions. The sonographic findings for the masses were variable: 25 of 29 masses (86%) were irregular in shape; 14 of 29 (48%) showed indistinct margins; and 9 (31%) were angular or spiculated. The orientation of the mass was not parallel in 6 of 29 cases (21%). Two of 29 masses (7%) showed an echogenic halo at the lesion boundary. Noncalcified DCIS tended to have a nonhigh nuclear grade and was frequently the noncomedo type. In addition, c-erb-B2 was more commonly expressed in calcified DCIS. CONCLUSIONS Imaging findings for noncalcified DCIS are relatively nonspecific and are frequently similar to those of invasive malignancy. This knowledge may be useful for detecting noncalcified DCIS, planning treatment, and predicting the prognosis.

Abstract
Lobular and ductal intraepithelial neoplasias reflect proliferations of immunophenotypically variable, biologically and morphologically diverse cells with a potential, not always realized, for progression to carcinoma by breaking through the barriers of the myoepithelial cell layer and basement membrane, ultimately invading the stroma. Starting with the lobular and then the ductal proliferations, this review will address the evolution of our understanding of these lesions; the problems associated with the conventional terminology of ductal hyperplasia, atypical hyperplasia, and carcinoma in situ; and reasons for and advantages of the intraepithelial neoplasia terminology.

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
PURPOSE To evaluate radiological findings of non-calcified ductal carcinoma in situ (DCIS) and to correlate those with histological features. MATERIALS AND METHODS From July 2002 to March 2006, 22 patients with histologically-proven non-calcified DCIS were included. Mammography was obtained in 19 patients, ultrasound in 18 patients, and both examinations in 15 patients. Radiological findings were evaluated according to the Breast Imaging Reporting and Data System by American College of Radiology. Histological tumor subtype and Van Nuys classification of DCIS were assessed. RESULTS Histological subtypes consisted of mixed type in 11 patients (50%), comedo in 4 (18%), cribriform in 4 (18%), papillary type in 2 (9%), and solid in one (5%). According to Van Nuys classification, group 3 DCIS was observed in 13 (59%) patients. In the 19 patients who underwent mammography, 13 patients presented with abnormal findings: focal asymmetry in 7 patients (37%), masses in 4 (21%), skin thickening in one (5%), and architectural distortion in one (5%). In the 18 patients who had received breast ultrasound, a mass was present in 15 (83%) patients and ductal changes in 3 patients (17%). Sixty percent of patients with masses on ultrasound had group 3 DCIS and 100% of patients with ductal change had group 1 DCIS (p = 0.017). CONCLUSION Diagnosis of non-calcified DCIS by mammography is not an easy task due to the lack of typical malignant calcifications or masses. High resolution ultrasound can be useful for detecting non-calcified DCIS, and ultrasound findings are correlated with histological features.

Abstract
OBJECTIVE The purpose of our study was to retrospectively compare the sonographic and pathologic features of screening-detected and symptomatic ductal carcinoma in situ (DCIS). MATERIALS AND METHODS Of 5,790 cases diagnosed as breast cancer at our institution between January 1998 and December 2005, 528 (9.1%) cases were DCIS. We found 106 screening-detected and 125 symptomatic DCIS lesions in 226 patients (age range, 20-77 years; mean age, 47.8 years) who underwent preoperative whole-breast sonography and mammography. Three radiologists reviewed the sonographic features of these 231 cases of DCIS by consensus according to Breast Imaging Reporting and Data System (BI-RADS). The pathologic features were also reviewed. Statistical comparisons were performed using the chi-square test, the Fisher's exact test, and the Mann-Whitney U test. RESULTS On sonography, masses (p < 0.001) and associated ductal change (p = 0.019) were more common in symptomatic than in asymptomatic patients. Associated microcalcifications and posterior shadowing were more frequently found in screening-detected than in symptomatic DCIS (p < 0.001). On mammography, microcalcifications were more common in screening-detected than in symptomatic DCIS, and masses were more common in symptomatic than in screening-detected DCIS (p < 0.001). No significant differences were seen in the pathologic features of the two groups. CONCLUSION Our results showed that differences exist in the sonographic features of screening-detected and symptomatic DCIS. Recognition of the many and varied sonographic appearances of DCIS might be helpful to decrease the false-negative rate of bilateral whole-breast sonography and to detect symptomatic mammographically occult DCIS when we use sonography to supplement mammography.

Abstract
BACKGROUND The purpose of this study was to describe clinical characteristics and outcome of mammographically and clinically detected new cancers in patients with previously diagnosed ductal carcinoma in situ (DCIS). METHOD Our database was searched to identify patients with a primary diagnosis of DCIS. Those with prior evidence of invasive carcinoma were excluded from the analysis. Cumulative incidence of new cancers was estimated according to the method of Gray. Survival times were estimated using the Kaplan Meier product limit method. RESULTS A total of 799 patients diagnosed and treated for DCIS were included in the analysis. Median age at diagnosis was 54 years (range 22-88 years) and median tumor size was 1.4 cm (range 0.2-15 cm). After a median follow-up of 2.9 years, 45 patients (5.6%) had a second event: 14 (31%) with in-situ and 31 (69%) with invasive disease. Median disease-free interval was 3.5 years (range 0.5-20.8 years). The majority of second events (63%) occurred in the opposite breast (P = 0.048) and the cumulative incidence at 5 years was 6.6%. Overall survival at 5 years was 97.4%; that for the second event was 76.1%. For mammography and self-palpation, respectively, the 5-year survival by method of detection of the second event was 63.2% and 100% (P = 0.08 with a 33% power to detect a difference). CONCLUSION Second events following DCIS occurs primarily in the opposite breast and have a negative impact on survival.

Abstract
In vitro data support a role for the alpha6beta4 integrin in tumor cell migration and invasion, particularly in breast carcinoma cells, but clinical data on this potentially important integrin are limited. The beta4 integrin subunit has been shown to cluster with genes characteristic of basal/myoepithelial cells in cDNA microarray analyses of breast cancer, and the subset of breast cancers with increased expression of genes characteristic of basal/myoepithelial cells appears to be particularly aggressive. The purpose of this study was to determine whether alpha6beta4 integrin expression correlates with aggressive clinicopathologic features of breast cancer and whether expression of this integrin has prognostic significance in early breast cancer. We evaluated tumor expression of the beta4 integrin subunit gene in a cohort of patients with early invasive breast carcinoma by in situ hybridization and correlated expression levels with multiple clinicopathologic characteristics. We also evaluated expression of laminin-5 protein, the principal ligand of alpha6beta4, in this patient cohort. Although we observed a slight trend towards decreased disease-free survival for patients whose tumors had high beta4 gene expression and coexpression of laminin-5, this did not reach statistical significance (P=0.11). However, we did observe a correlation between beta4 mRNA expression and both tumor size (P=0.01) and tumor nuclear grade (P<0.01). These results do not demonstrate prognostic significance for beta4 gene expression and/or laminin-5 protein expression in early breast cancer, but increased beta4 gene expression in larger tumors and in higher grade tumors does support a potential role for the alpha6beta4 integrin in tumor progression.

Abstract
Insulin resistance (IR) and obesity may be risk factors for breast cancer. The mechanism of IR in patients with cancer has not been fully clarified yet. This study was conducted to evaluate the possible role of circulating cytokines; tumor necrosis factor-alpha (TNF-alpha) and interleukin 6 (IL-6) in inducing IR in 20 overweight or obese patients with early stage breast cancer and to compare their levels with that of body mass index matched 20 healthy controls. IR was calculated by homeostasis model assessment (HOMA) method. Four groups were formed according to a 2.7 HOMA-IR cut-off value as breast cancer with or without IR and controls with or without IR. IL-6 and HOMA-IR values were found to be higher in breast cancer patients with IR compared to other groups. There was no significant difference in TNF-alpha levels between groups. HOMA-IR values correlated with estradiol and IL-6 levels in all breast cancer patients but not TNF-alpha. HOMA-IR values, serum insulin, estradiol and IL-6 levels in the receptor positive group were significantly higher than those of the receptor negative group. These results suggested a possible contribution of endogenous IL-6 production and hyperinsulinemia to the development of breast cancer in overweight or obese patients with prominent IR.

Abstract
Widespread use of screening mammography has resulted in a remarkable increase in the incidence (or detection rate) of ductal carcinoma in situ (DCIS). Axillary lymph node involvement in DCIS is reported to occur at a frequency of 1–12 per cent. Over the past few years, however, there has been increasing emphasis on axillary sampling, limited axillary dissection, and the potential role of sentinel lymph node biopsy. The clinical relevance of axillary lymph node biopsy or dissection remains unanswered. This retrospective analysis was performed on 171 patients who underwent treatment for DCIS at a tertiary care center over a period of 14 years. Clinical and tumor factors were evaluated, and the local, axillary, and systemic recurrence rates were noted. No axillary recurrences from the primary DCIS diagnosis were noted in the entire group of 171 patients. During a mean follow-up of 70 months, 10 patients (6%) developed recurrence in the ipsilateral breast. Six of these recurrences were in the form of DCIS, whereas, four recurred as invasive cancers. Nine patients developed a new primary (seven DCIS and two invasive) in the same breast but in a different quadrant. Two patients with ipsilateral invasive disease also developed systemic disease and eventually died of disease. During the same period, 10 patients (6%) developed DCIS, and seven patients (4%) developed invasive cancer in the contralateral breast. The data show that the risk of axillary recurrence in pure DCIS is, at most, extremely low and support the position that nodal sampling or dissection is unwarranted.

Abstract
BACKGROUND An increase in incidence of ductal carcinoma in situ (DCIS) of the breast has been documented, and concerns regarding overly aggressive treatment have been raised. This study was designed to evaluate the use of surgery and radiation therapy in treating DCIS. METHODS We used the National Cancer Institute's Surveillance, Epidemiology, and End Results database to assess treatment of patients with DCIS with no evidence of microinvasion who were diagnosed from January 1, 1992, through December 31, 1999. We assessed the rates of mastectomy, breast reconstruction, radiation therapy after lumpectomy, and axillary dissection. Associations were analyzed by logistic regression. RESULTS During the study period, 25 206 patients met selection criteria. The incidence of DCIS dramatically increased with time; however, the incidence of comedo lesions did not change. The rate of mastectomy decreased from 43% in 1992 to 28% in 1999, after controlling for age, race, tumor size, comedo histology, and geographic location. However, because of the increase in the diagnosis of DCIS, the age-adjusted incidence of mastectomy for DCIS in the population did not change (7.8 per 100 000 women in 1992 and 1999). Almost half the patients undergoing lumpectomy did not undergo radiation therapy (55% in 1992 and 46% in 1999); in those with comedo histology, 33% did not undergo radiation therapy after lumpectomy, even in 1999. Overall, patients were less likely to have axillary dissection over time (34% in 1992 versus 15% in 1999), yet the rate of axillary dissection was still high (30%) in patients undergoing mastectomy in 1999. Large, statistically and clinically significant variation by geographic location was found in treatment. CONCLUSIONS Treatment of DCIS changed in a clinically significant fashion between 1992 and 1999. Throughout this study, many patients were found to undergo aggressive surgical therapy, including mastectomy and axillary dissection, whereas others appeared to be undertreated, e.g., not receiving radiation therapy after lumpectomy, even in the presence of adverse histologic features. Variation in demographic and geographic factors indicates that at least some of these treatment differences reflect individual and institutional practice patterns that may be modifiable.

Abstract
Background The elective treatment for noninvasive breast carcinoma has not yet been established. As a result of mammographic screening programs, the incidence of noninvasive tumors has increased and has lead to the same controversy already present had with invasive carcinomas: mastectomy or conserving therapy. Methods Since 1990, 101 patients with noninvasive breast cancer were treated with irradiation following breast-conserving surgery. All the patients had irradiation of the whole breast (mean dose, 47.6 ± 1.2 Gy). The radiation dose boost to the tumor bed was delivered in 28.7% of the cases (mean dose, 21.03 ± 3.06 Gy), and in 71.3%, the boost was not administered. Results With a median follow-up of 34 months, survival is 100%. The disease-free survival at 5 years by the Kaplan-Meier method is 93.6 ± 8.65. Conclusions The conserving treatment is a valid option for treatment of patients with ductal carcinoma in situ.

Abstract
Until recently, conservative radiation therapy of breast cancer using a wedge-filter combined with rectangular tangential irradiation was widely carried out. This method of irradiation creates uniform dose distribution in the target, minimizing the radiation dose to the lung. However, this method of irradiation results in many cases in which the amount of dose in the irradiated area differs as a result of the shape and size of the breast. It is necessary to prevent excessive doses from reaching the lung. IMRT ensures a uniform dose to the target. Therefore, IMRT was examined because of the possibility that the normal tissue dose can be effectively utilized in cases of conservative radiation therapy of breast cancer by providing a minimum dose. To compare the irradiation of each method of rectangular tangential irradiation, an electronic compensator (ELC), and IMRT, which uses Dynamic MLC, we evaluated target dose uniformity, standard deviation, and target differential DVH in 13 examples. We evaluated the lung dose of the irradiated side (V(30), 30 Gy volume) of the lung to the volume of the lung on the irradiated side based on the report of Hernando.(6)) With this method of irradiation, irrespective of the difference in the shape and size of the target, dose uniformity with ELC was very good. IMRT can reduce the lung dose in comparison with the other irradiation methods. However, it is apt to cause a high-dose area in the irradiation field. In addition, it affects the target and the skin-extracting contour, and the dose to the skin surface declines. Although ELC cannot offer lung doses that are as low as those of IMRT, most of the 13 examples planned for cure with ELC showed rates of 22% of V(30) and below. In conservative radiation therapy of breast cancer, ELC is more effective than the rectangular tangential irradiation method and IMRT.

Abstract
Skin-sparing mastectomy with immediate breast reconstruction can provide an excellent cosmetic result. Despite its increasing popularity, few studies have assessed the risk of recurrence when the procedure is used for the treatment of ductal carcinoma in situ. To evaluate the oncologic safety of skin-sparing mastectomy used for the treatment of ductal carcinoma in situ, the recurrence rate was analyzed. Patients with ductal carcinoma in situ or invasive carcinoma or both who underwent skin-sparing mastectomy with immediate breast reconstruction between 1985 and 1994 and had a follow-up period of at least 6 years were included in this retrospective analysis. The recurrence rates were determined for invasive carcinoma (with or without foci of ductal carcinoma in situ) and ductal carcinoma in situ alone. A total of 221 patients were included, 177 patients with invasive carcinoma and 44 patients with ductal carcinoma in situ alone. The immediate breast reconstructions were performed with transverse rectus abdominis muscle (TRAM) flaps in 62 percent of patients, implants in 34 percent of patients, and latissimus dorsi myocutaneous flaps (with or without implants) in 4 percent of patients. The local recurrence rate was zero of 44 for patients with ductal carcinoma in situ and 5.6 percent (10 of 177) for patients with invasive carcinoma during a mean follow-up period of 9.8 years. There was a 6.8 percent (12 of 177) metastatic recurrence rate in the invasive carcinoma group. All recurrences were invasive ductal carcinoma. Of the patients with ductal carcinoma in situ alone, none developed metastatic disease. The combined metastatic and local recurrence rates for the invasive carcinoma group (n = 177) with each type of reconstruction were 13 percent (14 of 110), 12 percent (seven of 60), and 14 percent (one of seven) for TRAM flaps, implants, and latissimus dorsi flaps, respectively. The risk of recurrence following skin-sparing mastectomy and immediate breast reconstruction for ductal carcinoma in situ is low during this follow-up period. Therefore, skin-sparing mastectomy with immediate breast reconstruction seems to be a safe oncologic treatment option for ductal carcinoma in situ; however, a longer follow-up period is important to determine the long-term risk of recurrence.

Abstract
The objective of this review is to describe characteristic MR mammographic findings for signal increase and morphological patterns of enhancement in pure ductal carcinoma in situ (DCIS) and to differentiate between high grade and non-high grade lesions. The dynamic MR examination (1.5 T unit, contrast enhanced T(1) weighted two dimensional fast field echo, 96 ms repetition time, 5.0 ms echo time, 80 degrees flip angle) of 39 consecutive patients with pure DCIS was evaluated retrospectively. Categories were defined for signal increase (C1=normal, C2=slow, continuous, C3=strong initial and slow further increase, C4=strong initial increase followed by a plateau phenomenon, and C5=strong initial increase followed by a washout phenomenon) and morphological patterns (M0=no pattern observed, M1=linear or linear-branched, M2=segmental dotted or granular, M3=segmental homogeneous, and M4=focal spot-like). Time-intensity curves showing a C4 and C5 signal increase were considered suspicious for malignancy. All cases were correlated with histology. 62% of all tumours had a plateau or washout (C4, C5), 77% showed a strong initial signal increase (C3-C5). On evaluation of time-intensity curves alone MR mammography (MRM) findings were suspicious for malignancy in 62% of all DCIS cases. A segmental enhancement was found in 82% of all enhancing tumors and the M2 pattern in 73%. In a combined analysis of signal increase and morphology, 70% of non-high grade and 92% of high grade DCISs were correctly described as suspicious. The difference between non-high grade and high grade DCIS was not significant (p=0.148), while significant differences were found between G1 and G3 DCISs and between G1 and G2 DCISs (p<0.05). All G2 and G3 DCISs showed noticeable signal enhancement. The mean histological tumour size of non-high grade DCISs was smaller than that for high grade DCIS (p<0.05). The hallmark of DCIS on dynamic MRM was unilateral segmental enhancement, most commonly with a granular dotted morphology (M2). Hormone effects need to be considered as the main differential diagnosis. Signal enhancement kinetics similar to invasive carcinoma were seen in the majority of cases. A combined analysis of morphological pattern and signal enhancement considerably improved rate of detection. G2 and G3 DCISs were correctly diagnosed with a significantly higher rate of detection (92%) than G1 DCIS (53%) (p<0.05). Different average size of G1, G2 and G3 DCIS on pathology cannot be excluded as a reason for differences found. Normal MRM seems to exclude high grade DCIS.

Abstract
BACKGROUND We examined the relationship between biological markers, apoptotic indices and pathologic subtypes of ductal carcinoma in situ (DCIS) of the breast. The tumor-biological factors can be divided into invasive and proliferative markers. We chose urokinase-type plasminogen activator (uPA), plasminogen activator inhibitor type 1 (PAI-1) and Cathepsin D as invasive markers, and Ki-67 and C-erbB2 oncoproteins as proliferative factors for our study. METHODS We used immunohistochemical methods to investigate the expression of uPA, PAI-1, Cathepsin D, Ki-67, C-erbB2 and ssDNA (single-stranded DNA for apoptotic cells) in 20 cases of DCIS. Tumor histological grade and the immunohistochemical expression of invasive and proliferative markers were compared. RESULTS Histological grade is associated with C-erbB2, MIB-1, apoptotic index (AI) and expression of PAI-1 in cancer and stroma. The correlation coefficient of the MIB-1 index and AI was 0.867. Of these invasive markers, only expression of PAI-1 in tumor and in stroma was associated with C-erbB2. CONCLUSION Our results show that the apoptosis index is closely related to the MIB-1 index, and also suggest that the immunohistochemical detection of PAI-1 in the cytoplasm of both carcinoma cells and stromal cells of DCIS is related to histological grade and expression of the proliferative markers MIB-1 and C-erbB2. Therefore, we infer that both invasiveness and proliferation are affected by the tumorigenesis of DCIS.
