Abstract
PURPOSE To assess the effects of contemporary treatment of ductal carcinoma in situ (DCIS) on the risk of developing an ipsilateral invasive breast cancer (iIBC) in the Dutch female population. METHODS Clinical data was obtained from the Netherlands Cancer Registry (NCR), a nationwide registry of all primary malignancies in the Netherlands integrated with the data from PALGA, the Dutch nationwide network and registry of histo- and cytopathology in the Netherlands, on all women in the Netherlands treated for primary DCIS from 2005 to 2015, resulting in a population-based cohort of 14.419 women. Cumulative iIBC incidence was assessed and associations of DCIS treatment type with subsequent iIBC risk were evaluated by multivariable Cox regression analyses. RESULTS Ten years after DCIS diagnosis, the cumulative incidence of iIBC was 3.1% (95% CI: 2.6-3.5%) in patients treated by breast conserving surgery (BCS) plus radiotherapy (RT), 7.1% (95% CI: 5.5-9.1) in patients treated by BCS alone, and 1.6% (95% CI: 1.3-2.1) in patients treated by mastectomy. BCS was associated with a significantly higher risk for iIBC compared to BCS + RT during the first 5 years after treatment (HR 2.80, 95% CI: 1.91-4.10%). After 5 years of follow-up, the iIBC risk declined in the BCS alone group but remained higher than the iIBC risk in the BCS + RT group (HR 1.73, 95% CI: 1.15-2.61). CONCLUSIONS Although absolute risks of iIBC were low in patients treated for DCIS with either BCS or BCS + RT, risks remained higher in the BCS alone group compared to patients treated with BCS + RT for at least 10 years after DCIS diagnosis.

Imaging findings for response evaluation of ductal carcinoma in situ in breast cancer patients treated with neoadjuvant systemic therapy: a systematic review and meta-analysis. Eur Radiol 2023; 33:5423-5435. [PMID: 37020070 PMCID: PMC10326113 DOI: 10.1007/s00330-023-09547-7] [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: 09/01/2022] [Revised: 12/23/2022] [Accepted: 02/23/2023] [Indexed: 04/07/2023]
Abstract
OBJECTIVES In approximately 45% of invasive breast cancer (IBC) patients treated with neoadjuvant systemic therapy (NST), ductal carcinoma in situ (DCIS) is present. Recent studies suggest response of DCIS to NST. The aim of this systematic review and meta-analysis was to summarise and examine the current literature on imaging findings for different imaging modalities evaluating DCIS response to NST. More specifically, imaging findings of DCIS pre- and post-NST, and the effect of different pathological complete response (pCR) definitions, will be evaluated on mammography, breast MRI, and contrast-enhanced mammography (CEM). METHODS PubMed and Embase databases were searched for studies investigating NST response of IBC, including information on DCIS. Imaging findings and response evaluation of DCIS were assessed for mammography, breast MRI, and CEM. A meta-analysis was conducted per imaging modality to calculate pooled sensitivity and specificity for detecting residual disease between pCR definition no residual invasive disease (ypT0/is) and no residual invasive or in situ disease (ypT0). RESULTS Thirty-one studies were included. Calcifications on mammography are related to DCIS, but can persist despite complete response of DCIS. In 20 breast MRI studies, an average of 57% of residual DCIS showed enhancement. A meta-analysis of 17 breast MRI studies confirmed higher pooled sensitivity (0.86 versus 0.82) and lower pooled specificity (0.61 versus 0.68) for detection of residual disease when DCIS is considered pCR (ypT0/is). Three CEM studies suggest the potential benefit of simultaneous evaluation of calcifications and enhancement. CONCLUSIONS AND CLINICAL RELEVANCE Calcifications on mammography can remain despite complete response of DCIS, and residual DCIS does not always show enhancement on breast MRI and CEM. Moreover, pCR definition effects diagnostic performance of breast MRI. Given the lack of evidence on imaging findings of response of the DCIS component to NST, further research is demanded. KEY POINTS • Ductal carcinoma in situ has shown to be responsive to neoadjuvant systemic therapy, but imaging studies mainly focus on response of the invasive tumour. • The 31 included studies demonstrate that after neoadjuvant systemic therapy, calcifications on mammography can remain despite complete response of DCIS and residual DCIS does not always show enhancement on MRI and contrast-enhanced mammography. • The definition of pCR has impact on the diagnostic performance of MRI in detecting residual disease, and when DCIS is considered pCR, pooled sensitivity was slightly higher and pooled specificity slightly lower.

Abstract
INTRODUCTION As breast cancer treatment options have multiplied and biologic diversity within breast cancer has been recognized, the use of the same treatment strategies for patients with early-stage and favorable disease, and for those with biologically aggressive disease, has been questioned. In addition, as patient-reported outcome measures have called attention to the morbidity of many common treatments, and as the cost of breast cancer care has continued to increase, reduction in the overtreatment of breast cancer has assumed increasing importance. AREAS COVERED Here we review selected aspects of surgery, radiation oncology, and medical oncology for which scientific evidence supports de-escalation for invasive carcinoma and ductal carcinoma in situ, and assess strategies to address overtreatment. EXPERT OPINION The problems of breast cancer overtreatment we face today are based on improved understanding of the biology of breast cancer and abandonment of the 'one-size-fits-all' approach. As breast cancer care becomes increasingly complex, and as our knowledge base continues to increase exponentially, these problems will only be magnified in the future. To continue progress, the move must be made from advocating the maximum-tolerated treatment to advocating the minimum-effective one.

Radiological Underestimation of Tumor Size as a Relevant Risk Factor for Positive Margin Rate in Breast-Conserving Therapy of Pure Ductal Carcinoma In Situ (DCIS). Cancers (Basel) 2022; 14:cancers14102367. [PMID: 35625972 PMCID: PMC9139437 DOI: 10.3390/cancers14102367] [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: 02/24/2022] [Revised: 05/03/2022] [Accepted: 05/08/2022] [Indexed: 11/30/2022] Open
Abstract
Background: Radiological underestimation of the actual tumor size is a relevant problem in reaching negative margins in ductal carcinoma in situ (DCIS) associated with microcalcifications in breast-conserving therapy (BCT). The aim of this study is to evaluate whether the radiological underestimation of tumor size has an influence on the histopathological margin status. Methods: Patients who underwent BCT with preoperatively diagnosed pure DCIS were included (pooled analysis of two trials). Multiple factors were analysed regarding radiological underestimation ≥10 mm. Radiological underestimation was defined as mammographic minus histological tumor size in mm. Results: Positive margins occurred in 75 of 189 patients. Radiological underestimation ≥10 mm was an independent influencing factor (OR 5.80; 95%CI 2.55−13.17; p < 0.001). A radiological underestimation was seen in 70 patients. The following parameters were statistically significant associated with underestimation: pleomorphic microcalcifications (OR 3.77; 95%CI 1.27−11.18), clustered distribution patterns (OR 4.26; 95%CI 2.25−8.07), and mammographic tumor sizes ≤20 mm (OR 7.47; 95%CI 3.49−15.99). Only a mammographic tumor size ≤20 mm was an independent risk factor (OR 6.49; 95%CI 2.30−18.26; p < 0.001). Grading, estrogen receptor status, and comedo necrosis did not influence the size estimation. Conclusion: Radiological underestimation is an independent risk factor for positive margins in BCT of DCIS associated with microcalcifications predominantly occurring in mammographic small tumors.

Oncofertility and Reproductive Counseling in Patients with Breast Cancer: A Retrospective Study. J Clin Med 2022; 11:jcm11051311. [PMID: 35268402 PMCID: PMC8911138 DOI: 10.3390/jcm11051311] [Citation(s) in RCA: 21] [Impact Index Per Article: 10.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2021] [Revised: 02/22/2022] [Accepted: 02/25/2022] [Indexed: 12/25/2022] Open
Abstract
Introduction. Improving the prognosis of breast cancer patients is of utmost importance in terms of increasing survival rates. Modern medicine has therefore prioritized better quality of life for patients, even after the disease, through a better management of the potential long-term side effects induced by anticancer treatments. Fertility preservation and family planning are therefore crucial issues to be addressed in all cancer patients of reproductive age. Along those lines, a new branch of medicine with distinct multidisciplinary characteristics has developed over the years: oncofertility. Although both national and international guidelines value reproductive counseling as an essential aspect of the diagnostic-therapeutic pathway, part and parcel of the informed consent process, it is not included within the protocols adopted by the operating units for the care and management of neoplastic diseases. Objective. This study aimed to evaluate the activity of the Breast Unit of the Policlinico Umberto I Hospital, Rome, Italy, and the degree of compliance with guidelines. By knowing the strengths and weaknesses of such approaches, the standards of care offered to breast cancer patients can be improved. Materials and methods. A retrospective study based on a review of medical records was conducted between 2014 and 2021. Patients under 40 years of age diagnosed with non-metastatic malignancies were included who received chemotherapy treatment, namely neoadjuvant, adjuvant or adjuvant hormone therapy. Results. The data were extracted from the medical records of 51 patients who met the inclusion criteria, 41% of whom received reproductive counseling, and of these, 43% decided to undertake a path of fertility preservation. Factors such as the absence of children and young age reportedly favored both the interest in counseling proposals by the medical staff and the decision to undertake a path of fertility preservation. Conclusions. The study shows that there has been growing interest in the topic of oncofertility, especially in light of law 219/2017. Therefore, since 2018, multiple proposals for reproductive counseling have been set forth, but there was not an equally growing demand for fertility preservation practices, which can be explained by the invasive nature of such practices, the patients’ concern about their own state of health, and poor or inadequate information. Such impediments highlight the importance of standardized counseling and the need for a multidisciplinary medical team to support the patient in the decision-making process. The study also revealed a drop in the number of patients receiving counseling due to the COVID-19 pandemic, contrary to the positive trend that was recorded prior to the pandemic.

Abstract
PURPOSE The paucity of data on women with large (≥ 40 mm) DCIS tumors lead to uncertainty on the safety of breast-conserving surgery (BCS) for these patients. We evaluated the impact of large tumor size on local recurrence (LR) among women with DCIS treated with BCS ± radiotherapy (RT). METHODS Treatment and outcomes were ascertained through administrative databases for all women with DCIS in Ontario from 1994 to 2003 treated with BCS ± RT with negative margins; 82% had pathology review. Cox proportional hazards model was used to evaluate the impact of tumor size on LR. 10- and 15-year LR-free survival (LRFS) were calculated using Kaplan-Meier method. RESULTS The cohort includes 2049 women treated by BCS (N = 1073 with RT). Median follow-up is 14 years (IQR 9-17 years). Referenced to tumors ≤ 10 mm, the risk of LR following BCS was significantly higher for larger tumors: HR ≥ 40 mm = 3.67 (95% CI 2.13, 6.33; p < 0.001), HR 26-39 mm = 2.27 (95% CI 1.47, 3.50, p < 0.001), and HR 11-25 mm = 1.42 (95% CI 1.06, 1.92, p = 0.02). However, for individuals with BCS + RT, large tumor size was not associated with a significantly increased risk of LR (HR ≥ 40 mm = 1.92 (95% CI 0.97, 3.79); HR 26-39 mm = 1.81 (95% CI 1.09-2.99)). For women with tumors ≥ 40 mm, 10-year LRFS risk for those treated by BCS alone, BCS + RT without boost, and BCS + RT with boost was 58.9%, 82.8%, and 83.9%. CONCLUSION Large DCIS lesions ≥ 40 mm are associated with higher risks of LR following BCS, but high long-term LRFS rates can be achieved with the addition of breast RT.

Abstract
INTRODUCTION The 2016 consensus guideline on margins for breast-conserving surgery (BCS) with whole-breast irradiation (WBI) for ductal carcinoma in situ (DCIS) recommended 2 mm margins to decrease local recurrence rates. We examined re-excision rates, cost, and patient satisfaction before and after guideline implementation. METHODS From an Institutional Review Board-approved database, patients with DCIS who underwent BCS with over 1 year of follow-up at one academic institution and one community cancer center were evaluated. Two groups were compared based on when they received treatment, i.e. before (pre-consensus [PRE]) and after November 2016 (post consensus [POST]), with respect to outcome and cost parameters. RESULTS After consensus guideline implementation, re-excision rate (32.1% vs. 20.0%) and mastectomy conversion (8.3% vs. 2.3%) significantly increased, although total resection volume, operative cost per patient, and satisfaction with breast scores did not differ. Not all patients with <2 mm margins were re-excised, although the re-excision rate among this subset significantly increased (62.4% vs. 31.3%). On multivariable analysis controlling for age, estrogen receptor status, WBI use, and margin status, surgery after consensus guideline publication was independently associated with a higher re-excision rate (odds ratio [OR] 1.97, 95% confidence interval [CI] 1.08-3.59, p = 0.03) and a higher rate of conversion to mastectomy (OR 6.84, 95% CI 1.67-28.00, p = 0.007). CONCLUSIONS Implementation of the 2016 margin consensus guideline for DCIS resulted in an increase in re-excisions and mastectomy conversions at two institutions. Research is needed for operative tools and strategies to decrease DCIS re-excision rates.

Abstract
PURPOSE This study analyzes the potential of stromal platelet-derived growth factor receptor-beta (PDGFRb) expression as biomarker for radiotherapy (RT) benefit on ipsilateral breast events (IBE) in ductal carcinoma in situ (DCIS). Improved identification of DCIS patients refractory to adjuvant whole-breast RT is needed. Predictive biomarker studies in DCIS have focused on tumor cell features rather than the tumor-associated stroma, despite growing evidence of its influence on therapy efficiency. EXPERIMENTAL DESIGN Samples from the Swedish randomized radiotherapy DCIS trial (SweDCIS) were subjected to IHC analysis for stromal PDGFRb expression. IBE incidence at 10 years after breast-conserving surgery was the primary endpoint. Interactions between marker and treatment were analyzed. RESULTS PDGFRb score was predictive for RT benefit with regard to IBE (P interaction = 0.002 and P interaction = 0.008 adjusted multivariably). Patients of the PDGFRblow group had a strong benefit from RT regarding IBE risk [HR, 0.23; 95% confidence interval (CI), 0.12-0.45; P < 0.001] with an absolute risk reduction of 21% (cumulative risk 7% vs. 28%) at 10 years. No significant risk reduction by RT was observed for patients of the PDGFRbhigh group (HR, 0.83; 0.51-1.34; P = 0.444; cumulative risk 22% vs. 25%). The RT response-predictive effect of stromal PDGFRb was equally strong in analyses for in situ and invasive IBE when analyzed separately (in situ IBE: P = 0.029; invasive IBE: P = 0.044). CONCLUSIONS Results suggest high stromal PDGFRb expression as a novel biomarker identifying DCIS patients who are refractory to standard whole-breast adjuvant RT. The data imply previously unrecognized fibroblast-mediated modulation of radiosensitivity of DCIS, which should be further explored from mechanistic and targeting perspectives.

Abstract
Intraoperative radiation therapy (IORT) has been shown to reduce local recurrence rates among women with early-stage invasive ductal carcinoma, but data regarding its use among women with in situ carcinoma are limited. In this single-institution study, 50 women with in situ carcinoma were treated with oncoplastic breast-conserving surgery (OPS) and single-dose IORT. All 50 patients had "no tumor on ink," but 9 (16%) had margins < 2 mm and required additional therapy. No local recurrences were observed after a median follow-up of 46 months. Single-dose IORT is an efficacious treatment for well-selected patients with DCIS.

Abstract
Background To analyze the clinical efficacy of intraoperative radiotherapy (IORT) after breast-conserving surgery (BCS) in patients with early-stage breast cancer (BC), and to investigate the relationship between its influencing factors and clinical efficacy and prognosis. Methods A total of 73 patients with early-stage BC who underwent IORT after BCS in our hospital were selected in this research. Results Kaplan-Meier survival analysis was used to analyze the related factors of BCS and IORT of disease-free survival (DFS) and overall survival (OS). It was found that only age (χ2 = 14.035, P = 0.003) was statistically positively correlated with the patient’s DFS, and local recurrence and metastasis rate and mortality were higher in patients over 70 years old. Log rank test was used to analyze multiple factors. Only the diameter of the applicator (χ2 = 70.378, P < 0.05) was statistically significant with wound complications, and the larger the diameter, the higher incidence of wound complications. The remaining risk factors did not increase the incidence of wound complications. COX multivariate analysis showed that age was an independent risk factor for DFS rate and the risk factor had no significant effect on the OS rate of patients undergoing IORT after BCS. Conclusions IORT may be a safe form of treatment for the selected patients with early-stage BC, and can achieve satisfactory esthetic effect. Larger applicator diameters may increase the incidence of wound complications. Age is an independent risk factor for DFS in early-stage BC patients undergoing IORT after BCS.

Abstract
Purpose of Review Standard options for the treatment of ductal carcinoma in situ (DCIS) include breast-conserving surgery (BCS) alone; BCS with radiotherapy or endocrine therapy, or both; and mastectomy. Survival is excellent with all options, but rates of local recurrence (LR) vary, as do quality-of-life measures. Here we discuss treatment outcomes, risk factors for LR, and tools for risk estimation. Recent Findings After BCS, radiotherapy reduces the risk of LR by half, and endocrine therapy reduces the risk by a third. Young age, inadequate margins, and greater volume of disease are associated with higher risk of LR after BCS, while young age, high grade, and microinvasion are associated with higher risk of locoregional recurrence after mastectomy. Clinical tools, including the Memorial Sloan Kettering Cancer Center (MSKCC) DCIS nomogram, provide LR risk estimates after BCS that appear more accurate than current genomic assays. The safety of active surveillance for seemingly low-risk patients remains uncertain. Summary Estimation of LR risk, utilizing a multitude of clinicopathologic and treatment factors, can help a woman balance that risk with her values and priorities, and allow her to choose the optimal treatment option for her.

Abstract
PURPOSE Improved imaging, surgical techniques, and pathologic evaluation likely have decreased local recurrence rates for patients with ductal carcinoma in situ (DCIS). We present long-term outcomes of a large single-institution series after breast-conserving surgery (BCS) and adjuvant radiation therapy (RT). METHODS We retrospectively reviewed the records of 245 women treated for DCIS with BCS and RT between 2001 and 2007. Competing risk analysis was used to calculate local recurrence (LR) as a first event with the development of a second non-breast malignancy, contralateral breast cancer, and death as competing first events. RESULTS At a median follow-up of 10.6 years, 4 patients had a LR (2 DCIS, 2 invasive) as a first event with a cumulative LR incidence of 0.0% and 1.5% at 5 and 10 years, respectively. Most patients had > 2 mm margins (90%), specimen radiographs (93%), and received a tumor bed boost (99%). The majority (60%) of patients with hormone receptor-positive disease received adjuvant endocrine therapy. Ten-year cumulative incidence of contralateral breast cancer (CBC) was 7.9%, second non-breast malignancy was 4.5%, and death unrelated to breast cancer was 3.5%. Family history, age at diagnosis, and receipt of endocrine therapy were not significantly associated with the development of CBC (all P > 0.05). CONCLUSIONS With mature follow-up, our rates of local recurrence following breast-conserving therapy for DCIS remain very low (1.5% at 10 years). The incidence of CBC was higher than the LR incidence. Predisposing factors for the development of CBC are worthy of investigation.

Abstract
BACKGROUND A ductal carcinoma in situ (DCIS) Nomogram integrating 10 clinicopathologic/treatment factors and a Refined DCIS Score (RDS) that incorporates a genomic assay and three clinicopathologic factors (Oncotype DX DCIS Score) are available to estimate DCIS 10-year local recurrence risk (LRR). This study compared these estimates. METHODS Patients 50 years of age or older with DCIS size 2.5 cm or smaller and a genomic assay available were identified. An RDS within 1-2% of the range of Nomogram LRR estimates obtained by assuming use and non-use of endocrine therapy (Nomogram ± ET) was defined as concordant. Assuming a 10-year risk threshold of 10% for recommending radiation, Nomogram ± ET and RDS estimates were compared, and threshold concordance was determined. RESULTS For 54 (92%) of 59 patients, the RDS and Nomogram ± ET LRR estimates were concordant. For the remaining 5 (8%) of the 59 patients, the RDS LRR estimates were lower than the Nomogram + ET estimates, with an absolute difference of 3-8%, and thus were discordant. For these five patients, the RDS estimates of 10-year LRR were lower than 10% (range 5-8%) and the Nomogram + ET estimates were 10% or higher (range 11-14%). These five patients with both discordant and threshold-discordant estimates all had close margins (≤ 2 mm). CONCLUSIONS Among 92% of women 50 years of age or older with DCIS size 2.5 cm or smaller, free-of-charge online Nomogram 10-year LRR estimates were concordant with those obtained using the commercially available RDS (> $4600). Among the 8% with discordant risk estimates, the RDS appeared to underestimate the LRR and may lead to inappropriate omission of radiotherapy. Unless other data show a clinically significant advantage of the RDS (Oncotype DX DCIS Score), the study data suggest that for women 50 years of age or older with DCIS size 2.5 cm or smaller, its use is not warranted.

Abstract
High re-excision rates in breast-conserving surgery call for a new intraoperative approach to the lumpectomy margin evaluation problem. The unique intraoperative imaging system, presented here, demonstrated the capability of photoacoustic tomography (PAT) to deliver optical sensitivity and specificity, along with over 2-cm imaging depth, in a clinical setting. The system enabled the evaluation of tumor extent, shape, morphology, and position within lumpectomy specimens measuring up to 11 cm in diameter. The investigation included all major breast cancer-related lesions, such as invasive ductal carcinoma (IDC), multifocal IDC, ductal carcinoma in situ and combinations of these variants. Coregistration with established ultrasound (US) technology, as well as comparison to specimen radiography, validated the performance of PAT, which appeared to facilitate better tumor visualization. Contrary to expected PA contrast mechanisms, PAT images of hemoglobin distribution correlated poorly with US-determined tumor location, while hypointense regions in lipid-weighted PAT images were in better agreement with US.

Abstract
PURPOSE Better tools are needed to estimate local recurrence (LR) risk after breast-conserving surgery (BCS) for DCIS. The DCIS score (DS) was validated as a predictor of LR in E5194 and Ontario DCIS cohort (ODC) after BCS. We combined data from E5194 and ODC adjusting for clinicopathological factors to provide refined estimates of the 10-year risk of LR after treatment by BCS alone. METHODS Data from E5194 and ODC were combined. Patients with positive margins or multifocality were excluded. Identical Cox regression models were fit for each study. Patient-specific meta-analysis was used to calculate precision-weighted estimates of 10-year LR risk by DS, age, tumor size and year of diagnosis. RESULTS The combined cohort includes 773 patients. The DS and age at diagnosis, tumor size and year of diagnosis provided independent prognostic information on the 10-year LR risk (p ≤ 0.009). Hazard ratios from E5194 and ODC cohorts were similar for the DS (2.48, 1.95 per 50 units), tumor size ≤ 1 versus > 1-2.5 cm (1.45, 1.47), age ≥ 50 versus < 50 year (0.61, 0.84) and year ≥ 2000 (0.67, 0.49). Utilization of DS combined with tumor size and age at diagnosis predicted more women with very low (≤ 8%) or higher (> 15%) 10-year LR risk after BCS alone compared to utilization of DS alone or clinicopathological factors alone. CONCLUSIONS The combined analysis provides refined estimates of 10-year LR risk after BCS for DCIS. Adding information on tumor size and age at diagnosis to the DS adjusting for year of diagnosis provides improved LR risk estimates to guide treatment decision making.

Abstract
Background The objective of the present study was to evaluate the effectiveness of postoperative radiotherapy after breast conserving surgery (BCS) in DCIS in a large patient population treated in clinical practice. Methods Data were provided by the population-based Munich Cancer Registry. Between 1998 and 2014, 1048 female patients with diagnosis of DCIS and treated at two Breast Care Centres were included in this observational study. The effectiveness of postoperative radiotherapy and variables predicting the use of radiotherapy were retrospectively analysed. Results After adjusting for age, tumour characteristics and therapies, Cox regression analysis for local recurrence-free survival identified RT as an independent predictor for improved local control (HR: 0.579; 95%CI: 0.384–0.872, p = 0.008). Ten-year cumulative incidence of in-breast recurrences was 20.0% following BCS, compared to 13.6% in patients receiving postoperative radiotherapy (p = 0.012). As an estimate for disease-specific survival, 10-year relative survival was 105.4% for patients receiving postoperative radiotherapy and 101.6% without radiotherapy. On multivariate analysis, postoperative radiotherapy was not associated with improved overall survival (HR 0.526; 95%CI: 0.263–1.052, p = 0.069). Over time, a significant increase of RT was registered: while 1998 only 42.9% of patients received postoperative radiotherapy, the proportion rose to 91.2% in 2014. Women aged < 50 years (OR: 2.559, 95%CI: 1.416–4.625, p < 0.001) or with negative hormone receptor status (OR: 2.625, 95%CI: 1.458–4.728, p = 0.001) or receiving endocrine therapy (OR: 1.762, 95%CI: 1.060–2.927, p = 0.029) were more likely to receive postoperative radiotherapy after BCS. Conclusions In conclusion, this study provides insights regarding the adoption and treatment pattern of postoperative RT following BCS for DCIS in a large cohort reflecting “real-life” clinical practice in this setting. Postoperative RT was found to be associated with a reduced risk of ipsilateral recurrence and no survival benefit compared to observation alone.

Abstract
Ductal carcinoma in situ (DCIS) accounts for 20% of all newly diagnosed breast cancers. Mastectomy was once the gold standard for the treatment of DCIS; however, breast-conserving surgery (BCS) has been adopted as the treatment of choice for patients with small, screen-detected lesions. Both adjuvant radiation and hormonal therapy following BCS have been demonstrated in randomized trials to reduce the risk of both invasive and DCIS recurrence, but neither affects survival. With the variety of surgical and adjuvant treatment options available, there has been great interest in tailoring the treatment to the individual, with the goal of optimizing the balance of risks and benefits according to the values and priorities of the woman herself. Prospective studies of women with "low-risk" DCIS treated with BCS alone have successfully identified women at lower than average risk but have not achieved the goal of identifying a subset of women with DCIS at minimal risk of recurrence after surgical excision alone. No studies have evaluated the safety of medical management alone.

Abstract
BACKGROUND The current study was conducted to examine the association between ipsilateral breast tumor recurrence (IBTR) and the timing of radiotherapy (RT) in women with ductal carcinoma in situ (DCIS) undergoing breast-conserving surgery (BCS). METHODS Women with DCIS who were treated with BCS and RT from 1980 through 2010 were identified from a prospectively maintained database. IBTR rates, measured from the time of RT completion, were compared between those who initiated RT ≤8 weeks, >8 to 12 weeks, and >12 weeks after the completion of surgery. The association between RT timing and IBTR was evaluated by Kaplan-Meier and log-rank analyses; Cox modeling was used for multivariable analysis. RESULTS A total of 1323 women met the inclusion criteria. The median follow-up was 6.6 years, with 311 patients followed for ≥10 years. A total of 126 IBTR events occurred. Patients were categorized by RT timing: 806 patients (61%) with timing of ≤8 weeks, 386 patients (29%) with timing of >8 to 12 weeks, and 131 patients (10%) with timing >12 weeks. The 5-year and 10-year IBTR rates were 5.8% and 13.0%, respectively, for RT starting ≤8 weeks after surgery; 3.8% and 7.6%, respectively, for RT starting >8 to 12 weeks after surgery; and 8.8% and 23.0%, respectively, for an RT delay >12 weeks after surgery (P = .004). On multivariable analysis, menopause (hazard ratio [HR], 0.54; P = .0009) and endocrine therapy (HR, 0.45; P = .002) were found to be protective against IBTR, whereas a delay in RT >12 weeks compared with ≤8 weeks was associated with a higher risk of IBTR (HR, 1.92; P = .014). There was no difference in IBTR noted between RT initiation at ≤8 weeks and initiation at >8 to 12 weeks after BCS (P = .3). CONCLUSIONS A delay in RT >12 weeks is associated with a significantly higher risk of IBTR in women undergoing BCS for DCIS. Efforts should be made to avoid delays in starting RT to minimize the risk of disease recurrence. Cancer 2018;124:46-54. © 2017 American Cancer Society.

Abstract
INTRODUCTION Preoperative assessment of pure Ductal Carcinoma Insitu (DCIS) is essential in the surgical planning. The role of Magnetic resonance imaging (MRI) has long been debated. The impact of MRI on the management of High Grade (HG) DCIS was assessed, whether it accurately captures the true size of this entity in comparison to conventional imaging, and, if MRI use would reduce the number of re-excision surgery. METHOD Ninety-one consecutive patients with HG DCIS, who were identified from a prospectively collected data at Kettering General Hospital between April 2011 and December 2015. All patients had preoperative MRI scan in addition to the standard breast imaging. This was compared to a control group of consecutive patients (n=52) which was obtained from a period just before 2011. Impact on surgical planning and number of surgeries for each patient was compared. The size of HG DCIS estimated by MRI was compared to the final histological size. Secondary outcomes included change of initial surgical plan and detection of occult contralateral breast cancer. RESULTS MRI group had 91 patients with median age of 63. Seventy percent of which presented through the screening program. The overall sensitivity of MRI to detect HG DCIS was 77% (70/91) with a false negative rate FNR of 23% (21/91). Therefore, 70 patients only were included in the data analysis. The control group included 52 screening patients with comparable baseline characteristics. Re-excision (or completion mastectomy) rates were higher in the control group 26% compared to 8% in the MRI group (P-value 0.012). MRI use correctly converted the initial plan of breast conservation to mastectomy in 9 patients (13%). Five patients had additional ipsilateral malignant features (7%).Occult contra lateral disease, was diagnosed in 2 patients (3%). CONCLUSION This study suggests that MRI could be an important tool in reducing the re-excision rates in the surgical management of HG DCIS. Although still controversial, selective MRI imaging can be useful in the preoperative diagnosis and evaluation of HG DCIS. Case by case discussion at MDT is crucial. Wider adaptation of MRI when indicated in the assessment of breast lesions with proper correlation to histology postoperatively is a key in improving our MRI interpretation skills, helping us to exploit the full scope of this useful tool.

Abstract
BACKGROUND Women with ductal carcinoma in situ (DCIS) are increasingly choosing bilateral mastectomy. We sought to quantify rates of contralateral breast cancer (CBC) and ipsilateral breast tumor recurrence (IBTR) after breast-conserving surgery (BCS) for DCIS, and to compare risk factors for CBC and IBTR. METHODS From 1978 to 2011, DCIS patients undergoing BCS with a contralateral breast at risk were identified from a prospectively maintained database. The association of clinicopathologic and treatment factors with CBC and IBTR were evaluated using Kaplan-Meier analysis, multivariable Cox regression, and competing risk regression (CRR). RESULTS Of 2759 patients identified, 151 developed CBC and 344 developed IBTR. Five- and 10-year Kaplan-Meier CBC rates were 3.2 and 6.4%. Overall, 10-year IBTR rates were 2.5-fold higher than CBC rates, and, without radiation, 4-fold higher. On CRR, 5- and 10-year rates were 2.9 and 5.8% for CBC, and 7.8 and 14.5% for IBTR. CBC risk and invasive CBC risk were not significantly associated with age, family history, presentation, nuclear grade, year of surgery, or radiation. By multivariable Cox regression, endocrine therapy was associated with lower CBC risk (hazard ratio 0.57, p = 0.03). Ten-year risk of subsequent CBC in the subset of patients who developed IBTR was similar to the cohort as a whole (8.1 vs. 6.4%). CONCLUSIONS CBC rates were low across all groups, including those who experienced IBTR. CBC was not associated with factors that increase IBTR risk. While factors associated with IBTR risk are important in decision making regarding management of the index DCIS, they are not an indication for contralateral prophylactic mastectomy.

Abstract
Multimodal treatment approaches have substantially improved the outcome of breast cancer patients in the last decades. Radiotherapy is an integral component of multimodal treatment concepts used in curative and palliative intention in numerous clinical situations from precursor lesions such as ductal carcinoma in situ (DCIS) to advanced breast cancer. This review addresses current controversial topics in radiotherapy with special consideration of DCIS, accelerated partial breast irradiation (APBI) and regional nodal irradiation (RNI) and provides an update on the clinical practice guidelines of the Breast Cancer Expert Panel of the German Society of Radiation Oncology (DEGRO).

Abstract
Background Controversy exists regarding the optimal negative margin width for ductal carcinoma in situ (DCIS) treated with breast-conserving surgery and whole-breast irradiation (WBRT). Methods A multidisciplinary consensus panel used a meta-analysis of margin width and ipsilateral breast tumor recurrence (IBTR) from a systematic review of 20 studies including 7883 patients and other published literature as the evidence base for consensus. Results Negative margins halve the risk of IBTR compared with positive margins defined as ink on DCIS. A 2 mm margin minimizes the risk of IBTR compared with smaller negative margins. More widely clear margins do not significantly decrease IBTR compared with 2 mm margins. Negative margins less than 2 mm alone are not an indication for mastectomy, and factors known to impact rates of IBTR should be considered in determining the need for re-excision. Conclusion The use of a 2 mm margin as the standard for an adequate margin in DCIS treated with WBRT is associated with low rates of IBTR and has the potential to decrease re-excision rates, improve cosmetic outcome, and decrease health care costs. Clinical judgment should be used in determining the need for further surgery in patients with negative margins < 2 mm.

Abstract
Purpose Controversy exists regarding the optimal negative margin width for ductal carcinoma in situ (DCIS) treated with breast-conserving surgery and whole-breast irradiation. Methods A multidisciplinary consensus panel used a meta-analysis of margin width and ipsilateral breast tumor recurrence (IBTR) from a systematic review of 20 studies including 7,883 patients and other published literature as the evidence base for consensus. Results Negative margins halve the risk of IBTR compared with positive margins defined as ink on DCIS. A 2-mm margin minimizes the risk of IBTR compared with smaller negative margins. More widely clear margins do not significantly decrease IBTR compared with 2-mm margins. Negative margins narrower than 2 mm alone are not an indication for mastectomy, and factors known to affect rates of IBTR should be considered in determining the need for re-excision. Conclusion Use of a 2-mm margin as the standard for an adequate margin in DCIS treated with whole-breast irradiation is associated with lower rates of IBTR and has the potential to decrease re-excision rates, improve cosmetic outcomes, and decrease health care costs. Clinical judgment should be used in determining the need for further surgery in patients with negative margins narrower than 2 mm.

Ann Surg Oncol 2016; 23:2816-24.

Abstract
BACKGROUND Age is a known risk factor for recurrence in women with ductal carcinoma in situ (DCIS) treated with breast-conserving surgery (BCS). We explored the relationship between age, other risk factors, and recurrence. METHODS Using a prospectively maintained database of DCIS patients undergoing BCS from 1978 to 2010, the association of age and recurrence risk was analyzed using Kaplan-Meier estimates, multivariable analysis, and competing risk multivariable analysis. RESULTS Overall, 2996 cases were identified. Median follow-up for those without recurrence was 75 months; 732 were followed for ≥10 years, and 363 (12 %) had recurrence [192 (53 %) DCIS, 160 (44 %) invasive, 11 (3 %) unknown]. Risk of recurrence decreased with age, even after adjustment for eight clinicopathologic variables on multivariable analysis [hazard ratios (HR), with <40 years of age as the reference: 40-49 years, 0.82 (p = 0.36), 50-59 years, 0.46 (p = 0.0005), 60-69 years, 0.50 (p = 0.003), 70-79 years, 0.56 (p = 0.02), ≥80 years, 0.21 (p = 0.0015)]. This association persisted for cohorts with and without radiation therapy. Using competing risk multivariable analysis, the effect of age on invasive recurrence was empirically stronger than for DCIS recurrence. Ten-year invasive recurrence was 16 and 6.5 % in women <40 years of age and women ≥40 years of age, respectively. Only 0.6 % of the population ultimately developed distant disease; those <40 years of age constituted 4.7 % (141/2996) of the population, but 21 % (4/19) of those developed distant disease. CONCLUSIONS The risk of recurrence of DCIS decreases with age. This effect is particularly strong at the extremes of age and is independent of other clinicopathologic factors. The oldest women are at low risk of recurrence, while the youngest women have a higher overall, and especially invasive, recurrence rate, although mortality remains low. These findings should be incorporated into risk/benefit discussions of treatment options.

Do LORIS Trial Eligibility Criteria Identify a Ductal Carcinoma In Situ Patient Population at Low Risk of Upgrade to Invasive Carcinoma? Ann Surg Oncol 2016; 23:3487-3493.

Abstract
BACKGROUND The Surgery Versus Active Monitoring for Low-Risk DCIS (LORIS) trial is studying the safety of monitoring core-biopsy diagnosed low-risk ductal carcinoma in situ (DCIS) without excision. We sought to determine the incidence and characteristics of synchronous invasive carcinoma found in LORIS-eligible women who underwent excision, as this knowledge is essential in assessing the safety of observation alone. METHODS Women meeting LORIS eligibility criteria (age ≥46 years, screen-detected calcifications, non-high-grade DCIS diagnosed by core biopsy, absence of nipple discharge, or strong family history of breast cancer) who underwent surgical excision from 2009 to 2012 were identified. Histologic findings of excision specimens were reviewed. RESULTS Overall, 296 LORIS-eligible cases were identified; 58 (20 %) had invasive carcinoma on final pathology (90 % invasive ductal, 78 % >1 mm in size, 21 % high grade, 3 % triple negative, 9 % HER2 amplified). Of these, 18 (31 %) were pT1b or larger and 3 (5 %) were pN1. Among eligible upgraded cases, 90 % received radiation, 89 % received endocrine therapy, and 18 % were recommended chemotherapy. Women upgraded to invasive carcinoma were more likely to have intermediate-grade DCIS on core biopsy and to have undergone mastectomy. CONCLUSIONS Among LORIS-eligible women, 20 % had invasive carcinoma at surgical excision that was heterogeneous in grade, size, and receptor status. Information gained from surgical excision influenced receipt of adjuvant radiation and endocrine therapy in most patients, and indicated benefit from chemotherapy in 18 % of patients. Surgical excision is warranted until additional risk stratification is available to identify a cohort of DCIS patients at lower risk for clinically significant synchronous invasive carcinoma.

Abstract
BACKGROUND The purpose of the study was to identify the effect of final surgical margin (SM) status and re-excision on outcomes in patients with ductal carcinoma in situ (DCIS) who underwent breast conservation therapy (BCT). PATIENTS AND METHODS The study population consisted of women diagnosed with DCIS who underwent BCT between 1989 and 2014. All women received adjuvant whole breast radiation and a boost. The primary end point was local control (LC). Final SMs were defined according to margin width: negative SM was defined as > 2 mm, close SM was defined as > 0 to ≤ 2 mm, and a positive SM was defined as tumor on ink. The Cox proportional hazards model was used to determine predictors of outcomes on multivariable analysis. Actuarial incidence of LC was estimated using the Kaplan-Meier method. RESULTS A total of 498 patients were included; 400 patients had a final negative SM, 87 had a close SM, and 11 had a positive SM. A total of 172 patients received adjuvant hormonal therapy, 265 patients required ≥ 1 re-excision. Patients with positive or close SMs were more likely to receive a radiation dose > 60 Gy (P < .001) and undergo re-excision (P < .01). The 10-year LC rates were not significantly different between patients with a negative (93.5%), close (91.8%), or positive (100%) SM (P = .57). There was no difference in LC in patients who underwent re-excision for initial close or positive SMs (P = .55). CONCLUSION This single-institution experience showed that risks of local recurrence remain poorly characterized. Re-excision and whole breast radiation with boost resulted in excellent LC for women with DCIS. Trials aimed at personalized deintensified local therapy are warranted.
