DeLeire T, Mitchell JM, De La Cruz L, Isaacs C. Nonclinical factors associated with the treatment of older women with newly diagnosed low-grade ductal carcinoma in situ. Cancer 2024; 130:1041-1051. [PMID: 37987170 PMCID: PMC10939947 DOI: 10.1002/cncr.35124] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2023] [Revised: 09/30/2023] [Accepted: 10/27/2023] [Indexed: 11/22/2023]
Abstract
BACKGROUND Ductal carcinoma in situ (DCIS) is the most common form of noninvasive breast cancer and is associated with an excellent prognosis. As a result, there is concern about overdiagnosis and overtreatment of DCIS because most patients with DCIS are treated as though they have invasive breast cancer and undergo either breast-conserving surgery (BCS)-most commonly followed by radiation therapy (RT)-or mastectomy. Little research to date has focused on nonclinical factors influencing treatments for DCIS. METHODS Population-based data were analyzed from five state cancer registries (California, Florida, New Jersey, New York, and Texas) on women aged 65 years and older newly diagnosed with DCIS during the years 2003 to 2014 using a retrospective cohort design and multinominal logistic modeling. The registry records with Medicare enrollment data and fee-for-service claims to obtain treatments (BCS alone, BCS with RT, or mastectomy) were merged. Surgeon practice structure was identified through physician surveys and internet searches. RESULTS Patients of surgeons employed by cancer centers or health systems were less likely to receive BCS with RT or mastectomy than patients of surgeons in single specialty or multispecialty practices. There also was substantial geographic variation in treatments, with patients in New York, New Jersey, and California being less likely to receive BCS with RT or mastectomy than patients in Texas or Florida. CONCLUSIONS These findings suggest nonclinical factors including the culture of the practice and/or financial incentives are significantly associated with the types of treatment received for DCIS. Increasing awareness and targeted efforts to educate physicians about DCIS management among older women with low-grade DCIS could reduce patient harm and yield substantial cost savings.

Racial and Ethnic Disparities in Outcomes After Breast-Conserving Therapy and Endocrine Therapy for DCIS: A Post-Hoc Analysis of the NSABP B-35 Randomized Clinical Trial. Ann Surg Oncol 2023; 30:8404-8411.

Abstract
BACKGROUND Racial and ethnic disparities in outcomes after treatment for ductal carcinoma in situ (DCIS) are largely unknown. The objective of this study was to examine breast cancer outcomes by race and ethnicity in the National Surgical Adjuvant Breast and Bowel Project (NSABP) B-35 clinical trial. PATIENTS AND METHODS The NSABP B-35 trial randomized postmenopausal women with hormone receptor-positive DCIS treated with breast-conserving therapy to 5 years of tamoxifen or anastrozole. In total, 3104 women were enrolled between 2003 and 2006. For this analysis, patients without complete self-reported race and ethnicity or with immediate trial dropout were excluded. Kaplan-Meier curves and adjusted Cox-proportional hazards models were used for analyses. RESULTS Of the 3061 women included, 2614 (85.4%) were non-Hispanic white (NHW), 255 (8.3%) were non-Hispanic Black (NHB), 95 (3.1%) were Hispanic, and 96 (3.1%) were Asian or Pacific Islander (API). Endocrine therapy assignment and duration were well balanced between racial and ethnic groups. Median follow-up was 9 years; unadjusted Kaplan-Meier curves did not show any racial differences in disease events. Adjusted Cox-proportional hazards models found API (versus NHW) race to be associated with higher local recurrence [hazard ratio (HzR) 2.45, p = 0.035] and NHB race to be associated with higher distant recurrence (HzR 5.03, p = 0.020) and breast cancer mortality (HzR 3.83, p = 0.046). CONCLUSIONS Despite similar locoregional treatments and standard endocrine therapy in a clinical trial population, racial and ethnic disparities exist in long-term outcomes for hormone-receptor-positive DCIS. These findings suggest that factors outside of access and treatment may impact DCIS outcomes by race and ethnicity.

Survival outcomes after breast-conserving surgery plus radiotherapy compared with mastectomy in breast ductal carcinoma in situ with microinvasion. Sci Rep 2022; 12:20132. [PMID: 36418384 PMCID: PMC9684534 DOI: 10.1038/s41598-022-24630-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2022] [Accepted: 11/17/2022] [Indexed: 11/24/2022] Open
Abstract
Ductal carcinoma in situ with microinvasion (DCIS-MI) is a subtype of breast cancer with a good prognosis, for which both breast conserving surgery plus radiotherapy (BCS + RT) and mastectomy are feasible surgical methods, but no clear conclusion has been made on the choice of these treatments. We used the Surveillance, Epidemiology and End Results database to extract 5432 DCIS-MI patients. Participants were divided into the BCS + RT group and the mastectomy group. We compared the overall survival (OS) and breast cancer-specific survival (BCSS) of the two groups using the Kaplan-Meier method and Cox regressions before and after propensity score matching (PSM). Before PSM, both univariate and multivariate analyses showed that BCS + RT group had significantly higher OS and BCSS compared with patients in the mastectomy group (P < 0.001). After PSM, the multivariate analysis showed that compared with mastectomy, the BCS + RT showed significantly higher OS and BCSS (HR = 0.676, 95% CI = 0.540-0.847, P < 0.001; HR = 0.565,95% CI = 0.354-0.903, P = 0.017). In addition, the subgroup analysis showed that BCS + RT is at least equivalent to mastectomy with respect to OS and BCSS in any subgroup. For patients with DCIS-MI, the prognosis of BCS + RT was superior to mastectomy.

Molecular subtypes predict second breast events of ductal carcinoma in situ after breast‐conserving surgery. Cancer Med 2022; 11:2755-2766. [PMID: 35598318 PMCID: PMC9302274 DOI: 10.1002/cam4.4651] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2021] [Revised: 01/20/2022] [Accepted: 02/20/2022] [Indexed: 11/25/2022] Open
Abstract
Purpose Currently, the prognostic value of molecular subtypes in ductal carcinoma in situ (DCIS) remains unclear. In this study, we explored whether molecular subtypes could predict second breast events (SBEs) in patients after breast‐conserving surgery (BCS). Methods From January 2008 to December 2016, 291 DCIS patients treated with BCS were retrospectively analyzed. Patients were classified into four molecular subtypes: luminal A, luminal B, human epidermal growth factor receptor 2 (HER2) overexpression, and triple‐negative breast cancer (TNBC). The SBE incidence was calculated by the competing risk model and compared by Gray's test. The disease‐free survival rates were estimated by the Kaplan–Meier method and compared by the log‐rank test. Prognostic factors were evaluated by univariate and multivariate COX proportional hazards regression model. Results With a median follow‐up of 66 months, 12 SBEs were identified. The 5‐year overall SBE incidence of luminal A, luminal B, HER2 overexpression, and TNBC was 2.18%, 4.25%, 15.15%, and 0.00%, respectively. In the univariate analysis, the HER2 overexpression subtype was the predictor of overall (p = 0.005), in situ (p = 0.004), and ipsilateral SBEs (p = 0.008). Patients with endocrine therapy were less likely to develop in situ SBEs (p = 0.039). Additionally, patients with closed (<2 mm) or involved margins were related to a higher risk of contralateral SBEs (p = 0.029). In the multivariate analysis, the HER2 overexpression subtype remained of prognostic values for overall (p = 0.006), in situ (p = 0.029), and ipsilateral SBEs (p = 0.012). Conclusions The molecular subtype, especially the HER2 overexpression subtype, was the independent prognostic factor for DCIS patients who underwent BCS.

Abstract
Ductal carcinoma in situ (DCIS) is a non-obligate precursor of invasive ductal carcinoma (IDC), whereby if left untreated, approximately 12% of patients develop invasive disease. The current standard of care is surgical removal of the lesion, to prevent potential progression, and radiotherapy to reduce risk of recurrence. There is substantial overtreatment of DCIS patients, considering not all DCIS lesions progress to invasive disease. Hence, there is a critical imperative to better predict which DCIS lesions are destined for poor outcome and which are not, allowing for tailored treatment. Active surveillance is currently being trialed as an alternative management practice, but this approach relies on accurately identifying cases that are at low risk of progression to invasive disease. Two DCIS-specific genomic profiling assays that attempt to distinguish low and high-risk patients have emerged, but imperfections in risk stratification coupled with a high price tag warrant the continued search for more robust and accessible prognostic biomarkers. This search has largely turned researchers toward the tumor microenvironment. Recent evidence suggests that a spectrum of cell types within the DCIS microenvironment are genetically and phenotypically altered compared to normal tissue and play critical roles in disease progression. Uncovering the molecular mechanisms contributing to DCIS progression has provided optimism for the search for well-validated prognostic biomarkers that can accurately predict the risk for a patient developing IDC. The discovery of such markers would modernize DCIS management and allow tailored treatment plans. This review will summarize the current literature regarding DCIS diagnosis, treatment, and pathology.

Abstract
BACKGROUND This study compared the recurrence risk of single versus dual adjuvant radiotherapy (RT) and hormonal therapy (HT) following breast-conserving surgery (BCS) in patients with hormone receptor-positive ductal carcinoma in situ (DCIS). METHODS This retrospective cohort study used the Taiwan Cancer Registry database linking to the Taiwan National Health Insurance data from 2011 to 2016. We compared the recurrence risk between BCS-based regimens in Cox regressions and presented as adjusted hazard ratio (HR) and 95% confidence interval (95%CI). RESULTS The 1,836 study cohort with a low-to-intermediate risk of recurrence was grouped into BCS alone (6.1%), BCS+RT (6.2%), BCS+HT (23.4%) and BCS+HT+RT (64.3%) according to the initial treatments. During the follow-up (median: 3.3 years), the highest 5-year recurrence-free survival rate was in BCS+RT (94.1%) group and followed by BCS+HT+RT (92.8%), BCS+HT (87.4%) and BCS alone (84.9%). Of the single adjuvant therapies, RT was more effective than HT. Both BCS+HT (HR: 1.52, 95%CI: 0.99-2.35) and BCS+RT (HR: 1.10, 95%CI: 0.50-2.41) did not significantly increase recurrence risk comparing against the BCS+HT+RT group. CONCLUSION Single adjuvant demonstrated a similar subsequent recurrence risk with dual adjuvant. This study supports the proposition to de-escalate adjuvant treatments in patients with low-to-intermediate risk of DCIS recurrence.

Abstract
Background We explored the hypothesis that high-quality standards in diagnostic mammography can lead to an early diagnosis of breast cancers and identifies at risk populations outside screening programs. The histopathological features and distribution of the TNM classification were examined in relation to patient age in a large group of women with breast cancers participating in the Quality Assured Mamma Diagnostic (QuaMaDi) program of the state of Schleswig–Holstein. Patients and methods Surgical pathological reports were studied for clinicopathological characteristics, receptor status, molecular subtype and tumor stage. The analysis was conducted by dividing the study population into three age groups: women under 50 years (pre-screening), 50–69 years (peri-screening) and over 70 years (post-screening). Results 7.111 biopsies and 2.887 resection specimens were included. Breast cancer was diagnosed in 4.241 (59.7%) cases, one fourth of them in women < 50 years. Elderly women (> 70 years) had more well-differentiated, estrogen receptor (ER)-positive and HER2-negative carcinomas, whereas younger women (< 50 years) tended to have more poorly differentiated, ER negative, and HER2-positive carcinomas. 47% of breast carcinoma were luminal B tumors and were most common regardless of age. 70.4% of resected specimen had pT1 stage. Nodal negative were 71.2%. Conclusion In QuaMaDi breast cancer was diagnosed at an early and potentially curable stage of the disease due to high-quality standards in diagnostic mammography. In addition, regardless of age, an increased number of prognostically unfavorable molecular subtypes were detected. Thus, QuaMaDi helps to identify at risk populations. QuaMaDi significantly improves diagnostic mammography and complements mammography screening programs.

Abstract
The impact of HER2 status in ductal carcinoma in situ (DCIS) on the risk of progression to invasive ductal carcinoma (IDC) has been debated. We aim to use a national database to identify patients with known HER2 status to elucidate the effect of HER2 overexpression on ipsilateral IDC (iIDC) development. We performed survival analysis on patient-level data using the U.S. NCI's Surveillance Epidemiology and End Results program. We identified patients diagnosed with DCIS who underwent lumpectomy and had known HER2 status. Competing risks analysis was performed. A total of 1,540 patients had known HER2 status and met inclusion criteria. Median age at diagnosis was 60, median follow-up time was 44.5 months. A total of 417 (27.1%) patients were HER2 positive and 1,035 (67.2%) were HER2 negative. Twenty-two (1.4%) patients developed iIDC and 27 (1.8%) developed ipsilateral in situ or contralateral disease. The estimated cumulative incidence of iIDC at 5 years was 1.9% for all patients, 1.2% for HER2-negative and borderline patients, and 3.9% for HER2-positive patients. On multivariate competing risks regression, two factors were significant for iIDC: radiation (protective) therapy within 24 months (HR, 0.05; P = 0.00006) and HER2 overexpression (increased likelihood; HR, 2.72; P = 0.044). Patients with HER2-positive DCIS were more likely to have recurrences with receptor discordance. HER2 may serve as a prognostic factor for invasive recurrence and was the only lesion-related factor to significantly relate to iIDC development. It may also be associated with receptor discordance of recurrences. Further large studies will be needed to confirm these results.

Abstract
Ductal carcinoma in situ (DCIS) shows overlapping epidemiology with invasive ductal carcinoma of the breast, sharing similar risk factorssuch as age, mammographic density, family history, and hormonal therapy as well as genetic factors such as BRCA1/BRCA2, histotypes, and molecular subtypes such as luminal A and B, HER2 enriched, and basal-type, thus suggesting its potential precursor role. A small percentage of patients with a history of DCIS die without a documented intermediate diagnosis of invasive breast carcinoma (IBC). The increased risk of death is usually associated with ipsilateral recurrence such as IBC. The slightly variable incidence of DCIS in different countries is mainly due to a different diffusion of mammographic screening and variability of the risk factors. The majority of DCIS lesions are not palpable lesions, which can be only radiologically detected because of the association with microcalcifications. Mammography is a highly sensitive diagnostic procedure for detecting DCIS with microcalcifications, while magnetic resonance imaging (MRI) is considered more sensitive to detect DCIS without calcifications and/or multifocal lesions. The aim of the present overview was to focus on the clinical, radiological, and pathological features of DCIS of the breast, with an emphasis on the practical diagnostic approach, predictive prognostic factors, and therapeutic options.

The impact of patient characteristics and lifestyle factors on the risk of an ipsilateral event after a primary DCIS: A systematic review. Breast 2020; 50:95-103. [PMID: 32120064 PMCID: PMC7073883 DOI: 10.1016/j.breast.2020.02.006] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2019] [Accepted: 02/10/2020] [Indexed: 11/21/2022] Open
Abstract
Objective The majority of ‘low-risk’ (grade I/II) Ductal Carcinoma In Situ (DCIS) may not progress to invasive breast cancer during a women’s lifetime. Therefore, the safety of active surveillance versus standard surgical treatment for DCIS is prospectively being evaluated in clinical trials. If proven safe and selectively implemented in clinical practice, a significant group of women with low-risk DCIS may forego surgery and radiotherapy in the future. Identification of modifiable and non-modifiable risk factors associated with prognosis after a primary DCIS would also enhance our care of women with low-risk DCIS. Methods To identify modifiable and non-modifiable risk factors for subsequent breast events after DCIS, we performed a systematic literature search in PUBMED, EMBASE and Scopus. Results Six out of the 3870 articles retrieved were included for final data extraction. These six studies included a total of 4950 patients with primary DCIS and 640 recorded subsequent breast events. There was moderate evidence for an association of a family history of breast cancer, premenopausal status, high BMI, and high breast density with a subsequent breast cancer or further DCIS. Conclusion There is a limited number of recent studies published on the impact of modifiable and non-modifiable risk factors on subsequent events after DCIS. The available evidence is insufficient to identify potential targets for risk reduction strategies, reflecting the relatively small numbers and the lack of long-term follow-up in DCIS, a low-event condition. Need for risk management strategies for untreated DCIS patients. Limited evidence for association between lifestyle factors and prognosis after DCIS. Positive family history, premenopausal status, high breast density associated with prognosis.

Abstract
Ductal carcinoma in situ (DCIS) of the breast is a group of heterogeneous epithelial proliferations confined to the milk ducts that nearly always present in asymptomatic women on breast cancer screening. A stage 0, preinvasive breast cancer, increased detection of DCIS was initially hailed as a means to prevent invasive breast cancer through surgical treatment with adjuvant radiation and/or endocrine therapies. However, controversy in the medical community has emerged in the past two decades that a fraction of DCIS represents overdiagnosis, leading to unnecessary treatments and resulting morbidity. The imaging hallmarks of DCIS include linearly or segmentally distributed calcifications on mammography or nonmass enhancement on breast MRI. Imaging features have been shown to reflect the biological heterogeneity of DCIS lesions, with recent studies indicating MRI may identify a greater fraction of higher-grade lesions than mammography does. There is strong interest in the surgical, imaging, and oncology communities to better align DCIS management with biology, which has resulted in trials of active surveillance and therapy that is less aggressive. However, risk stratification of DCIS remains imperfect, which has limited the development of precision therapy approaches matched to DCIS aggressiveness. Accordingly, there are opportunities for breast imaging radiologists to assist the oncology community by leveraging advanced imaging techniques to identify appropriate patients for the less aggressive DCIS treatments.

Abstract
Ductal carcinoma in situ (DCIS) is a neoplastic proliferation of mammary ductal epithelial cells confined to the ductal-lobular system, and a non-obligate precursor of invasive disease. While there has been a significant increase in the diagnosis of DCIS in recent years due to uptake of mammography screening, there has been little change in the rate of invasive recurrence, indicating that a large proportion of patients diagnosed with DCIS will never develop invasive disease. The main issue for clinicians is how to reliably predict the prognosis of DCIS in order to individualize patient treatment, especially as treatment ranges from surveillance only, breast-conserving surgery only, to breast-conserving surgery plus radiotherapy and/or hormonal therapy, and mastectomy with or without radiotherapy. We conducted a semi-structured literature review to address the above issues relating to "pure" DCIS. Here we discuss the pathology of DCIS, risk factors for recurrence, biomarkers and molecular signatures, and disease management. Potential mechanisms of progression from DCIS to invasive cancer and problems faced by clinicians and pathologists in diagnosing and treating this disease are also discussed. Despite the tremendous research efforts to identify accurate risk stratification predictors of invasive recurrence and response to radiotherapy and endocrine therapy, to date there is no simple, well-validated marker or group of variables for risk estimation, particularly in the setting of adjuvant treatment after breast-conserving surgery. Thus, the standard of care to date remains breast-conserving surgery plus radiotherapy, with or without hormonal therapy. Emerging tools, such as pathologic or biologic markers, may soon change such practice. Our review also includes recent advances towards innovative treatment strategies, including targeted therapies, immune modulators, and vaccines.

Virchows Arch 2018; 473:275-283.

Abstract
We compared the characteristics, clinical behavior, and biomarker profile between HER2 positive (HER2+) and triple-negative (TN) ductal carcinoma in situ (DCIS) which are considered more aggressive than other DCIS subtypes. In addition, we explored the impact of these features on its potential of progression to invasive breast carcinomas. Cases of DCIS diagnosed at the Department of Pathology, Singapore General Hospital from 1994 to 2010 were identified. TN and HER2+ DCIS cases formed the study cohort. Immunohistochemistry (IHC) was performed for ER, PR, HER2, CK14, EGFR, and p53. Comparisons of clinicopathological features, IHC results, and clinical outcomes were performed between the two groups. We evaluated 145 HER2+ and 85 TN DCIS cases. HER2 positive DCIS had significantly higher nuclear grade (p < 0.001) and more frequent necrosis (p < 0.001) than TN DCIS. HER2 positive DCIS also harbored significantly higher rates of nuclear p53 immunoreactivity (p = 0.002) than TN DCIS. Younger patients (age < 40) with HER2+ and TN DCIS demonstrated statistically significant worse invasive DFS than older women (p < 0.001). Multivariate cox regression analysis (HR 15.08, 95% CI 12.79-81.45, p = 0.002) also confirmed these findings. In addition, younger patients (age < 40) with HER2+ DCIS experienced significantly poorer prognosis when p53 was also positive (p = 0.033). HER2+ DCIS had more aggressive pathological characteristics compared to TN DCIS; accumulation of mutant p53 could possibly be contributory. Age was an independent predictor of aggressive biological behavior of HER2+ and TN DCIS. We demonstrated that younger patients with p53 positive HER2+ DCIS had significantly adverse clinical outcome.

Abstract
Objective Management of ductal carcinoma in situ (DCIS) remains controversial. This study examined long-term outcomes in a population-based cohort of patients with pure DCIS treated with breast-conserving surgery (BCS) alone, BCS + radiotherapy (RT), and mastectomy. Outcomes were compared between patients referred versus not referred for oncologic assessment after definitive surgery. Materials and methods Subjects were 2575 women diagnosed between 1985 and 1999. Data from several electronic databases were linked and analyzed. Outcomes were invasive local recurrence-free survival (ILRFS), mastectomy-free survival (MFS), breast cancer-specific survival (BCSS), and overall survival (OS). Results Median follow-up time was 9.8 years. Overall, 56% (n = 1448) of subjects were referred to a cancer centre. Factors associated with non-referral were older age, comorbidities, and travel distance. Ten-year MFS, BCSS, and OS were higher among referred patients (all p ≤ 0.001). In cohorts treated with BCS alone (n = 1314) vs. BCS + RT (n = 510) vs. mastectomy (n = 751), 10-year ILRFS were 93.7% vs. 96.6% vs. 97.7%, (p < 0.001) and BCSS were 97.6% vs. 99.8% vs. 98.6%, (p = 0.01). Corresponding rates of ipsilateral invasive breast relapse at 10 years were 6.3% after BCS alone, 3.4% after BCS + RT, and 2.3% after mastectomy (p < 0.001). On multivariable analysis, factors associated with improved ILRFS were older age at diagnosis, low comorbidity score, absence of comedo histology, mastectomy, and post-BCS RT. Conclusion Patients with DCIS referred for oncologic assessment were more likely to undergo post-BCS RT, resulting in lower mastectomy and higher survival rates compared to non-referred patients. Patients with significant comorbidities were less likely to be referred and experienced lower ILRFS and BCSS. Referral for multidisciplinary oncologic assessment after surgery is warranted to individualize management and optimize outcomes for patients with DCIS.

Abstract
Most patients with ductal carcinoma in situ of the breast (DCIS) are eligible for breast conservation treatment. The key management decision is whether to add radiotherapy and/or endocrine therapy to minimize the risk of a subsequent recurrence. Recent analyses indicating a lack of benefit in terms of breast cancer-associated mortality have suggested that more conservative approaches, omitting adjuvant therapy or even surgery, may be advisable in selected patients. These mortality observations are directly influenced by widespread use of mammographic screening which has opened a Pandora's box of subclinical DCIS and early invasive lesions. Confusion as to how aggressively such possibly indolent lesions should be treated has led to misunderstandings among patients and medical professionals. While awaiting further prospective evidence from clinical trials, we endorse an active treatment of DCIS as the standard of care. Our rationale is twofold: invasive recurrences are associated with an increase in breast cancer mortality, which is not the only relevant endpoint for DCIS. The benefit of complete surgical excision, adjuvant radiotherapy and endocrine treatment in preventing recurrence and invasive progression has been demonstrated in DCIS. The challenge now is how to identify DCIS patients who will not progress to invasive carcinoma even without complete excision and, at the other extreme, those patients at the highest risk who require mastectomy for local control. The current controversies over whether and which adjuvant therapy should be implemented can at least in part be addressed by developing effective doctor-patient communications that enable mutual understanding about the management of this biologically heterogeneous disease.

Abstract
Ductal carcinoma in situ (DCIS) accounts for ~20-25% of breast cancers. While DCIS is not life-threatening, it may progress to invasive carcinoma over time, and treatment intended to prevent invasive progression may itself cause significant morbidity. Accurate risk assessment is therefore necessary to avoid over- or undertreatment of an individual patient. In this review we will outline the evidence for current management of DCIS, discuss approaches to DCIS risk assessment and challenges facing identification of novel DCIS biomarkers.

Abstract
The primary aim in the management of DCIS is the prevention of recurrence and contralateral tumor. Risk factors for DCIS recurrence and appropriate treatments are still widely debated. Adjuvant therapies after surgical resection reduce recurrences and contralateral disease, but these treatments have significant financial costs, side effects and there is a group of low-risk patients who would not gain additional benefit. The aim of our analysis was to identify clinical-pathological features and treatment modalities associated with recurrence in DCIS and microinvasive carcinoma. In the Thomas Jefferson University Cancer Registry of Philadelphia, we identified 865 patients with DCIS or micro-invasive carcinoma treated between 2003 and 2013. Associations between recurrence and demographic factors (age at diagnosis, ethnicity), biological features (ER, PR and HER2) and treatment modalities (surgery, radiotherapy and endocrine treatment) were assessed. Our single institution register-based study showed that distribution of age at diagnosis and biological features did not significantly differ among ethnic groups. Younger women and micro-invasive carcinoma patients were more likely to undergo mastectomy, while African Americans were more likely to take endocrine therapy and undergo radiotherapy. In our sample only ER/PR negative DCIS were associated with significantly higher recurrence rate. Moreover, we reported a high rate of HER2 positive recurrences, suggesting that expression of this oncogene may represent a potential biomarker for DCIS at high risk of recurrence. To better define the molecular profile of the subgroup at worse prognosis might help to identify biomarkers predictive of recurrence or second tumors, identifying patients candidates for more appropriate treatments.

Abstract
An estimated 60,290 new cases of breast carcinoma in situ are expected to be diagnosed in 2015, and approximately 1 in 33 women is likely to receive an in situ breast cancer diagnosis in her lifetime. Although in situ breast cancers are relatively common, their clinical significance and optimal treatment are topics of uncertainty and concern for both patients and clinicians. In this article, the American Cancer Society provides information about occurrence and treatment patterns for the 2 major subtypes of in situ breast cancer in the United States-ductal carcinoma in situ and lobular carcinoma in situ-using data from the North American Association of Central Cancer Registries and the 13 oldest Surveillance, Epidemiology, and End Results registries. The authors also present an overview of in situ breast cancer detection, treatment, risk factors, and prevention and discuss research needs and initiatives.

Accelerated partial breast irradiation through brachytherapy for ductal carcinoma in situ: factors influencing utilization and risks of second breast tumors. Breast Cancer Res Treat 2015; 151:199-208. [PMID: 25893591 DOI: 10.1007/s10549-015-3389-0] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2015] [Accepted: 04/11/2015] [Indexed: 10/23/2022]
Abstract
The purpose of this study was to examine influencing factors and outcomes of accelerated partial breast irradiation through brachytherapy (APBIb) versus whole breast irradiation (WBI) for ductal carcinoma in situ (DCIS). From the Surveillance Epidemiology and End Results program of the US National Cancer Institute, we identified 40,749 women who were diagnosed with first primary DCIS between 2002 and 2011 and treated with breast-conserving surgery and radiotherapy. A multi-level logistic regression analysis was performed to estimate odds ratios of APBIb use. Hazard ratios (HRs) of developing ipsilateral breast tumors (IBTs) and contralateral breast tumors (CBTs) were analyzed in 1962 patients with APBIb and 7203 propensity score-matched patients with WBI, using Cox proportional hazards regression. Overall, 2212 (4.5 %) of 40,749 women (the whole cohort) received APBIb. Factors associated with the increased use of APBIb included older age, non-Hispanic white race/ethnicity, smaller tumor size, hormone receptor positivity, comedo subtypes, and urban residence. During the 46-month follow-up, 74 (0.8 %) and 131 (1.4 %) of 9165 propensity score-matched patients developed IBTs and CBTs, respectively. Compared with WBI, APBIb was associated with a significantly increased risk of IBTs (HR 1.74; 95 % CI 1.06-2.85) but not CBTs (OR 0.91; 95 % CI 0.59-1.41). This population-based study suggests that APBIb use for DCIS was influenced by patient and tumor characteristics as well as urbanization of residence. We observed a moderately increased IBT risk associated with APBIb versus WBI, suggesting that APBIb should be used with caution for DCIS before data from randomized controlled trials with long-term follow-ups are available.

Abstract
Recognition of breast cancer disparities between African-American and White American women has generated exciting research opportunities investigating the biologic and hereditary factors that contribute to the observed outcome differences, leading to international studies of breast cancer in Africa. The study of breast cancer in women with African ancestry has opened the door to unique investigations regarding breast cancer subtypes and the genetics of this disease. International research efforts can advance our understanding of race/ethnicity-associated breast cancer disparities within the USA; the pathogenesis of triple negative breast cancer; and hereditary susceptibility for breast cancer.

Abstract
The purpose of the study was to examine the impact of race/ethnicity on second breast tumors among women with ductal carcinoma in situ (DCIS). We identified 102,489 women diagnosed with primary DCIS between 1988 and 2009 from the 18 NCI-SEER Registries. Cox proportional hazard regression was used to estimate race/ethnicity-associated relative risks (RRs) and their 95 % confidence intervals (CI) of ipsilateral breast tumors (IBT; defined as DCIS or invasive carcinoma in the ipsilateral breast) and contralateral breast tumors (CBT; defined as DCIS or invasive carcinoma in the contralateral breast). Overall, 2,925 women had IBT and 3,723 had CBT. Compared with white women, black (RR 1.46; 95 % CI 1.29-1.65), and Hispanic (RR 1.18; 95 % CI 1.03-1.36) women had higher IBT risk, which was similar for invasive IBT and ipsilateral DCIS. A significant increase in IBT risk among black women persisted, regardless of age at diagnosis, treatment, tumor grade, tumor size, and histology. The CBT risk was significantly increased among black (RR 1.21; 95 % CI 1.08-1.36) and Asian/PI (RR 1.16; 95 % CI 1.02-1.31) women compared with white women. The association was stronger for invasive CBT among black women and for contralateral DCIS among Asian/PI women (P heterogeneity < 0.0001). The black race-associated CBT risk was more pronounced among women ≥50 years at diagnosis and those with comedo DCIS; in contrast, a significant increase in risk among Asian/PI women was restricted to those <50 years and those with noncomedo DCIS. Racial/ethnic differences in risks of second breast tumors after DCIS could not be explained by pathologic features and treatment.

Abstract
The purpose of this study was to better understand older women's experience with breast cancer treatment decisions. We conducted a longitudinal study of non-demented, English-speaking women ≥ 65 years recruited from three Boston-based breast imaging centers. We interviewed women at the time of breast biopsy (before they knew their results) and 6 months later. At baseline, we assessed intention to accept different breast cancer treatments, sociodemographic, and health characteristics. At follow-up, we asked women about their involvement in treatment decisions, to describe how they chose a treatment, and influencing factors. We assessed tumor characteristics through chart abstraction. We used quantitative and qualitative analyses. Seventy women (43 ≥ 75 years) completed both interviews and were diagnosed with breast cancer; 91 % were non-Hispanic white. At baseline, women 75+ were less likely than women 65-74 to report that they would accept surgery and/or take a medication for ≥ 5 years if recommended for breast disease. Women 75+ were ultimately less likely to receive hormonal therapy for estrogen receptor positive tumors than women 65-74. Women 75+ asked their surgeons fewer questions about their treatment options and were less likely to seek information from other sources. A surgeon's recommendation was the most influential factor affecting older women's treatment decisions. In open-ended comments, 17 women reported having no perceived choice about treatment and 42 stated they simply followed their physician's recommendation for at least one treatment choice. In conclusion, to improve care of older women with breast cancer, interventions are needed to increase their engagement in treatment decision-making.

Abstract
PURPOSE To determine the rate of underestimation of ductal carcinoma in situ (DCIS) diagnosed at imaging-guided biopsy and to analyze its association with HER2/neu oncogene, an important biomarker in assessing the tumour aggressiveness and guiding hormone therapy for breast cancer. METHODS We retrospectively reviewed 162 patients with DCIS diagnosed by imaging-guided core needle biopsy between January 2008 and March 2013. All of these patients received surgical excision, and in 25, the diagnosis was upgraded to invasive breast cancer. In this study, we examined the ultrasound, mammographic features and histopathological results for each patient, and compared these parameters between those with and without HER2/neu overexpression. RESULTS Of the 162 DCIS lesions, 110 (67.9%) overexpressed HER2/neu. Nineteen patients with HER2/neu overexpressing DCIS (n=19/110, 17.3%) were upgraded after surgery to a diagnosis of invasive breast cancer. In this group, the upgrade rate was highest in patients with a dilated mammary duct pattern (42.1%, n=8/19, p=0.02) and the presence of abnormal axillary nodes (40.0%, n=12/30, p<0.01) at ultrasound and was significantly associated with comedo tumour type on pathology. CONCLUSIONS Biopsy may underestimate the invasive component in DCIS patients. Sonographic findings of dilated mammary ducts and presence of abnormal axillary lymph nodes may help predicting the invasive components and possibly driving more targeted biopsy procedures.

Abstract
BACKGROUND Little information exists on lifestyle factors that affect prognosis after treatment for ductal carcinoma in situ (DCIS) breast cancer. Improved understanding of the role of lifestyle factors is important to survivors wishing to reduce their risk of a second breast cancer diagnosis. METHODS We examined the association between body mass index (BMI), physical activity, and alcohol intake, and risk of a second breast cancer diagnosis among 1,925 DCIS survivors in the Wisconsin In Situ Cohort. Exposures were self-reported during biennial patient interviews. Second breast cancer diagnoses were validated via pathology report. Cox proportional hazards regression was used to estimate the association between prediagnosis, postdiagnosis, and change in exposure levels and the risk of a second diagnosis, with adjustment for patient, tumor, and treatment factors. RESULTS Over a mean of 6.7 years of follow-up, 162 second breast cancer diagnoses were reported, including 57 invasive events, 60 in situ events, and 45 diagnoses of unknown stage. A significant trend of increasing risk of a second diagnosis was found over increasing categories of postdiagnosis alcohol intake (Ptrend = 0.02). Among premenopausal women, increased prediagnosis BMI was associated with a reduced risk of a second diagnosis (HR = 0.93; 95% confidence interval, 0.88-0.99). CONCLUSION DCIS survivors may reduce their risk of a second diagnosis by reducing postdiagnosis alcohol consumption. IMPACT The population of DCIS survivors is projected to surpass one million by the year 2016. Our results suggest that these women may be able to reduce their risk of a second diagnosis through moderation of alcohol consumption.

Abstract
BACKGROUND In general population studies, obesity has been associated with risk of high-grade prostate cancer, but little is known about obesity and future prostate cancer risk among men with an initial benign biopsy of the prostate; a high-risk population. METHODS Within a cohort of 6,692 men followed up after a biopsy or transurethral resection of the prostate (TURP) with benign findings, a nested case-control study was conducted of 494 prostate cancer cases and controls matched on age, race, follow-up duration, biopsy versus TURP and date of procedure. Body mass index at the time of the initial procedure was abstracted from medical records, and initial biopsy specimens were reviewed for the presence of prostatic intraepithelial neoplasia (PIN). RESULTS Obesity was associated with the presence of PIN in the initial benign specimen [OR = 2.15; 95% confidence interval (CI) 1.13-4.11]. After adjustment for the matching variables, family history of prostate cancer, prostate-specific antigen (PSA) levels at the initial procedure, the number of PSA tests and digital rectal examinations during follow-up, obesity (OR = 1.57; 95% CI, 1.07-2.30) at the time of the initial procedure was associated with prostate cancer incidence during follow-up. Risk associated with obesity was confined to cases with follow-up less than 1,538 days, the median duration of follow-up among cases (OR = 1.95; 95% CI, 1.09-3.48). CONCLUSIONS Obesity is associated with the presence of PIN in benign specimens and with future prostate cancer risk after an initial benign finding. IMPACT Obesity may be a factor to consider when planning clinical follow-up after a benign biopsy.

Abstract
Ductal carcinoma in situ is a proliferation of malignant epithelial cells confined to the ductolobular system of the breast. It is considered a pre-cursor lesion for invasive breast cancer and when identified patients are treated with some combination of surgery, +/− radiation therapy, and +/adjuvant tamoxifen. However, no good biomarkers exist that can predict with accuracy those cases of DCIS destined to progress to invasive disease or once treated those patients that are likely to suffer a recurrence; thus, in the era of screening mammography it seems likely that many patients with DCIS are overtreated. This paper details the parameters that should be included in a pathology report for a case of DClS with some explanations as to their importance for good clinical decision making.

Abstract
BACKGROUND The impact of race and ethnicity on the biologic features and outcome variables of women who are diagnosed with preinvasive breast cancer-ductal carcinoma in situ (DCIS)-has not been addressed widely in the published literature. METHODS Patient demographic, clinical, and pathologic features and outcome variables were analyzed with respect to the patient's initial self-reported race/ethnicity among women who received treatment for a diagnosis of pure DCIS from 1996 to 2009. RESULTS Of 1902 patients, 1411 were white (74.2%), 214 were African American (11.3%), 175 were Hispanic (9.1%), and 102 were Asian/Pacific Islander (5.4%). The majority of patients were between ages 41 and 70 years (83%). Patients of Hispanic and Asian/Pacific Islander descent were significantly younger than white and African American patients (P < .001). DCIS size and grade, the presence of necrosis, and the frequency of breast-conserving surgery did not differ significantly between groups. African American patients aged >70 years and Hispanic patients aged <50 years were significantly more likely to have estrogen receptor-positive DCIS than patients of other races in the same age categories (P < .001). Adjuvant radiotherapy and tamoxifen were received significantly less often by white women (P < .001). At a median follow-up of 4.8 years (range, 1-14 years), recurrence rates and the development of contralateral breast cancer did not differ significantly among racial/ethnic groups when stratified by treatments received. CONCLUSIONS There was variation in age at presentation, biologic features, and treatment of DCIS among the different ethnic groups. Additional studies with larger numbers of ethnic minority patients are needed to confirm whether the consistent application of evidence-based treatment practices presents an opportunity for reducing disparities in patients with DCIS.

Abstract
PURPOSE Given the paucity of data on racial disparities in ductal carcinoma in situ (DCIS), the data from a multi-institutional cohort of DCIS patients treated with breast-conserving surgery and whole breast radiation therapy (RT) were analyzed to determine whether racial disparities or differences exist. METHODS AND MATERIALS A total of 533 white and 76 black DCIS patients from 3 university-based cancer centers were uniformly treated with breast-conserving surgery and RT. All patient data were collected and analyzed as a function of race. RESULTS The median follow-up was 5.2 years. No significant racial differences were seen in tumor size, age at diagnosis, estrogen receptor status, necrosis, or grade (all P>.05). Of the treatment parameters, the RT dose delivered, boost, positive margin rates, frequency of hormone receptor status assessment, and receipt of hormonal therapy for the 2 cohorts did not significantly differ (all P>.05). The local relapse-free survival was similar at 5 years (96.1% and 98.1%, P=.399) and 10 years (92.8% vs 95.8%, P=.360), with no significant overall survival difference at 10 years (94.0% vs 88.9%, P=.290) between the white and black patients, respectively. On multivariate analysis, race was not an independent predictor of local relapse-free survival or overall survival when accounting for age, grade, and margin status. CONCLUSION In our large cohort of DCIS patients uniformly treated at 3 institutions with breast conservation without any apparent differences in treatment delivery parameters, we demonstrated that the clinical and pathologic features and local survival outcomes did not differ as a function of race. Our results suggest that when black patients with DCIS are appropriately selected for breast conservation and receive adjuvant RT without racial disparities in the treatment parameters, differences in the outcomes as a function of race do not exist.

Abstract
PURPOSE Some recent trials suggest that postoperative adjuvant radiotherapy (RT) may be safely omitted after breast-conserving surgery (BCS) for some patients with ductal carcinoma in situ (DCIS). In this study, we reviewed clinical outcomes of patients with DCIS treated with partial mastectomy (PM) without adjuvant RT. MATERIALS AND METHODS Medical records of 28 patients (29 breasts) with DCIS who were treated with PM, but without RT, between April 1991 and December 2010 were retrospectively analyzed. Based on established criteria (2.0 cm or less in size and no comedonecrosis), 18 patients were treated without RT after PM. Seven patients (8 breasts) who did not receive RT due to refusal were also included in this study. Three other patients were excluded because data concerning comedonecrosis were not available. RESULTS For the 25 patients included in this study, the mean age of the 18 patients who met the criteria was 47.9±6.2 years, and 47.6±12.7 years for the 7 patients who did not. The mean sizes of the primary tumors were 0.6±0.4 cm and 0.9±0.3 cm, respectively, in these two groups. Among these 25 patients (26 breasts) treated without RT, we observed no ipsilateral breast tumor recurrence or mortality within a mean follow-up of 84 months. CONCLUSION Based on this small number of cases, patients with DCIS, who were selected for tumor size less than 2 cm and absence of comedonecrosis, may be treated successfully with BCS; adjuvant RT may be omitted.

J Pathol 2011; 225:565-73.

Abstract
Ductal carcinoma in situ (DCIS) is a non-obligate precursor of invasive breast cancer. The current recognition that DCIS lesions exhibit inter- and intra-lesion diversity suggests that the process of evolution to invasive breast cancer is more complex than previously recognized. Here we demonstrate the reproducible growth of primary DCIS cells derived from patient's surgical and biopsy samples by the mouse intraductal (MIND) model. MIND involves injection of cells into the NOD-SCID IL2Rgamma$^{{\rm{null}}}$ (NSG) mouse mammary ducts. Twelve (eight unique and four repeats) DCIS and two atypical hyperplasia specimens, heterogeneous with respect to biomarker expression and histology, were injected into 48 mouse mammary glands and analysed for successful xenotransplantation. Overall, 14/34 and 11/14 MIND xenotransplanted glands contained human DCIS and atypical hyperplastic cells, respectively, after 8 weeks, which formed single and multi-layered epithelium inside the ducts, and were heterogeneous with respect to expression of human cytokeratins, oestrogen receptor α (ER), and HER2. ER protein expression was recapitulated in MIND xenografts at ratios similar to the corresponding patient biopsies. In both patient biopsies and corresponding MIND xenografts, HER2 protein expression and nuclear HER2 gene overexpression were restricted to the DCIS lesions and were not found in the surrounding stroma or normal ducts. The xenografted DCIS lesions recapitulate the pathology and heterogeneity of human disease, thus providing a powerful tool for the characterization of the distinct cellular and molecular basis of inter- and intra-tumoural heterogeneity and the processes of DCIS to early invasive breast cancer progression.

Abstract
While ductal carcinoma in situ (DCIS) is seldom life threatening, the management of DCIS remains a dilemma for patients and their physicians. Aggressive treatment reduces the risk of ipsilateral breast tumor recurrence (IBTR), but has never been proven to improve survival. There is interest in identifying the prognostic factors for determining low-risk DCIS patients, but a comprehensive review of high-quality evidence on tumor characteristics in predicting local recurrence has never been carried out. We examined the following tumor characteristics: biomarkers, comedonecrosis, focality, surgical margin, method of detection, tumor grade, and tumor size. For this systematic review we restricted the analyses to the results of subgroup analyses from randomized controlled trials (RCTs) and multivariate analyses from RCTs and observational studies. We identified 44 eligible articles. The pooled random-effects risk estimates for IBTR are comedonecrosis 1.71(95% CI, 1.36-2.16), focality 1.95(95% CI, 1.59-2.40), margin 2.25(95% CI, 1.77-2.86), method of detection 1.35(95% CI, 1.12-1.62), tumor grade 1.81(95% CI, 1.53-2.13), and tumor size 1.63(95% CI, 1.30-2.06). Limited evidence indicated that women whose DCIS is ER-negative, PR-negative, or HER2/neu receptor positive have an IBTR higher than those whose DCIS is ER-positive, PR-positive, and HER2/neu receptor negative. A variety of tumor characteristics are significant predictors for IBTR. These results are important for both clinicians and patients to interpret the risk of local recurrence and to decide on a course of treatment.
