Abstract
Multiple tools exist to assess a patient's breast cancer risk. The choice of risk model depends on the patient's risk factors and how the calculation will impact care. High-risk patients-those with a lifetime breast cancer risk of ≥20%-are, for instance, eligible for supplemental screening with breast magnetic resonance imaging. Those with an elevated short-term breast cancer risk (frequently defined as a 5-year risk ≥1.66%) should be offered endocrine prophylaxis. High-risk patients should also receive guidance on modification of lifestyle factors that affect breast cancer risk.

An absence of equipoise: Examining surgeons' decision talk during encounters with women considering breast cancer surgery. PLoS One 2021; 16:e0260704. [PMID: 34914705 PMCID: PMC8675712 DOI: 10.1371/journal.pone.0260704] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2021] [Accepted: 11/15/2021] [Indexed: 11/25/2022] Open
Abstract
Shared decision-making is recommended for decisions with multiple reasonable options, yet clinicians often subtly or explicitly guide choices. Using purposive sampling, we performed a secondary analysis of 142 audio-recorded encounters between 13 surgeons and women eligible for breast-conserving surgery with radiation or mastectomy. We trained 9 surgeons in shared decision-making and provided them one of two conversation aids; 4 surgeons practiced as usual. Based on a published taxonomy of treatment recommendations (pronouncements, suggestions, proposals, offers, assertions), we examined how surgeons framed choices with patients. Many surgeons made assertions providing information and advice (usual care 71% vs. intervention 66%; p = 0.54). Some made strong pronouncements (usual care 51% vs. intervention 36%; p = .09). Few made proposals and offers, leaving the door open for deliberation (proposals usual care 21% vs. intervention 26%; p = 0.51; offers usual care 40% vs. intervention 40%; p = 0.98). Surgeons were significantly more likely to describe options as comparable when using a conversation aid, mentioning this in all intervention group encounters (usual care 64% vs. intervention 100%; p<0.001). Conversation aids can facilitate offers of comparable options, but other conversational actions can inhibit aspects of shared decision-making.

Impact of consensus guidelines for breast-conserving surgery in patients with ductal carcinoma in situ. Cancer Rep (Hoboken) 2021; 5:e1502. [PMID: 34245135 PMCID: PMC9124516 DOI: 10.1002/cnr2.1502] [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: 05/12/2021] [Revised: 06/13/2021] [Accepted: 06/29/2021] [Indexed: 11/07/2022] Open
Abstract
Background Consensus guidelines published in 2016 recommended a 2 mm free margin as the standard for negative margins in patients undergoing breast‐conserving surgery (BCS) for ductal carcinoma in situ (DCIS). The goal of the guideline recommendation was standardization of re‐excision practices. Aims To evaluate the impact of this consensus guideline on our institutional practices. Methods We identified all patients at our institution with pure DCIS who were initially treated with BCS from September 2014 to August 2018 using a prospectively‐maintained institutional database. A retrospective chart review was performed to determine margin status and re‐excision rates during the 2 years before and the 2 years after the guideline was published in order to determine the effect on our re‐excision rates. Close margins were defined as <2 mm. Results In the 2 years before the consensus guideline was published, 184 patients with DCIS underwent BCS. Twenty‐six patients had positive margins and 24 underwent re‐excision, including three who had completion mastectomy. Of the remaining 159 patients, 76 had ≥2 mm (negative) margins. The remaining 82 patients had close margins and 48 of these patients (58.5%) underwent re‐excision, including one who had a completion mastectomy. Excluding the patients with positive margins, our re‐excision rate was 30.4% prior to the guideline. In the 2 years after the consensus guideline was published, 192 patients with DCIS underwent initial BCS. Twenty‐four patients had positive margins and 22 underwent re‐excision, including three who had completion mastectomy. Of the remaining 168 patients, 95 patients had ≥2 mm (negative) margins. The remaining 73 patients had close margins and 45 of those patients (61.6%) underwent re‐excision, including six who had completion mastectomy. Excluding the patients with positive margins, our re‐excision rate was 26.8% after the guideline. Conclusions Our institution's re‐excision rate did not change significantly during the 2 years before and after the publication of the consensus guideline on adequate margins for patients undergoing BCT for DCIS. Our overall re‐excision rate decreased slightly. However, of the patients who had close margins, a larger proportion underwent re‐excision after the guideline was published. The guideline publication appears to have affected our institutional practices slightly, but not dramatically as many of our surgeons' practices were comparable to the guideline recommendations prior to 2016. We continue to use clinical judgment based on patient and tumor characteristics in deciding which patients will benefit from margin re‐excision.

What matters most: Randomized controlled trial of breast cancer surgery conversation aids across socioeconomic strata. Cancer 2020; 127:422-436. [PMID: 33170506 PMCID: PMC7983934 DOI: 10.1002/cncr.33248] [Citation(s) in RCA: 35] [Impact Index Per Article: 8.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/18/2020] [Revised: 08/02/2020] [Accepted: 08/18/2020] [Indexed: 01/17/2023]
Abstract
Background Women of lower socioeconomic status (SES) with early‐stage breast cancer are more likely to report poorer physician‐patient communication, lower satisfaction with surgery, lower involvement in decision making, and higher decision regret compared to women of higher SES. The objective of this study was to understand how to support women across socioeconomic strata in making breast cancer surgery choices. Methods We conducted a 3‐arm (Option Grid, Picture Option Grid, and usual care), multisite, randomized controlled superiority trial with surgeon‐level randomization. The Option Grid (text only) and Picture Option Grid (pictures plus text) conversation aids were evidence‐based summaries of available breast cancer surgery options on paper. Decision quality (primary outcome), treatment choice, treatment intention, shared decision making (SDM), anxiety, quality of life, decision regret, and coordination of care were measured from T0 (pre‐consultation) to T5 (1‐year after surgery. Results Sixteen surgeons saw 571 of 622 consented patients. Patients in the Picture Option Grid arm (n = 248) had higher knowledge (immediately after the visit [T2] and 1 week after surgery or within 2 weeks of the first postoperative visit [T3]), an improved decision process (T2 and T3), lower decision regret (T3), and more SDM (observed and self‐reported) compared to usual care (n = 257). Patients in the Option Grid arm (n = 66) had higher decision process scores (T2 and T3), better coordination of care (12 weeks after surgery or within 2 weeks of the second postoperative visit [T4]), and more observed SDM (during the surgical visit [T1]) compared to usual care arm. Subgroup analyses suggested that the Picture Option Grid had more impact among women of lower SES and health literacy. Neither intervention affected concordance, treatment choice, or anxiety. Conclusions Paper‐based conversation aids improved key outcomes over usual care. The Picture Option Grid had more impact among disadvantaged patients. Lay Summary The objective of this study was to understand how to help women with lower incomes or less formal education to make breast cancer surgery choices. Compared with usual care, a conversation aid with pictures and text led to higher knowledge. It improved the decision process and shared decision making (SDM) and lowered decision regret. A text‐only conversation aid led to an improved decision process, more coordinated care, and higher SDM compared to usual care. The conversation aid with pictures was more helpful for women with lower income or less formal education. Conversation aids with pictures and text helped women make better breast cancer surgery choices.
A paper‐based pictorial conversation aid (pictures plus text) is beneficial to all patients with early‐stage breast cancer and particularly to disadvantaged patients. Between‐surgeon variation suggests that the maximal impact of such interventions requires standardized physician training combined with these interventions.

Predictors of Locoregional Recurrence After Failure to Achieve Pathologic Complete Response to Neoadjuvant Chemotherapy in Triple-Negative Breast Cancer. J Natl Compr Canc Netw 2020; 17:348-356. [PMID: 30959467 DOI: 10.6004/jnccn.2018.7103] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2018] [Accepted: 11/05/2018] [Indexed: 11/17/2022]
Abstract
BACKGROUND This study evaluated factors predictive of locoregional recurrence (LRR) in women with triple-negative breast cancer (TNBC) treated with neoadjuvant chemotherapy who do not experience pathologic complete response (pCR). METHODS This is a single-institution retrospective review of women with TNBC treated with neoadjuvant chemotherapy, surgery, and radiation therapy in 2000 through 2013. LRR was estimated between patients with and without pCR using the Kaplan-Meier method. Patient-, tumor-, and treatment-specific factors in patients without pCR were analyzed using the Cox proportional hazards method to evaluate factors predictive of LRR. Log-rank statistics were then used to compare LRR among these risk factors. RESULTS A total of 153 patients with a median follow-up of 48.6 months were included. The 4-year overall survival and LRR were 70% and 15%, respectively, and the 4-year LRR in patients with pCR was 0% versus 22.0% in those without (P<.001). In patients without pCR, lymphovascular space invasion (LVSI; hazard ratio, 3.92; 95% CI, 1.64-9.38; P=.002) and extranodal extension (ENE; hazard ratio, 3.32; 95% CI, 1.35-8.15; P=.009) were significant predictors of LRR in multivariable analysis. In these patients, the 4-year LRR with LVSI was 39.8% versus 15.0% without (P<.001). Similarly, the 4-year LRR was 48.1% with ENE versus 16.1% without (P=.002). In patients without pCR, the presence of both LVSI and ENE were associated with an even further increased risk of LRR compared with patients with either LVSI or ENE alone and those with neither LVSI nor ENE in the residual tumor (P<.001). CONCLUSIONS In patients without pCR, the presence of LVSI and ENE increases the risk of LRR in TNBC. The risk of LRR is compounded when both LVSI and ENE are present in the same patient. Future clinical trials are warranted to lower the risk of LRR in these high-risk patients.

Single-Institution Phase 1/2 Prospective Clinical Trial of Single-Fraction, High-Gradient Adjuvant Partial-Breast Irradiation for Hormone Sensitive Stage 0-I Breast Cancer. Int J Radiat Oncol Biol Phys 2020; 107:344-352. [PMID: 32084524 DOI: 10.1016/j.ijrobp.2020.02.021] [Citation(s) in RCA: 17] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2019] [Revised: 02/05/2020] [Accepted: 02/07/2020] [Indexed: 12/13/2022]
Abstract
PURPOSE We sought to evaluate the feasibility and tolerability of a novel accelerated partial breast irradiation regimen delivered in a single fraction postoperatively. METHODS AND MATERIALS We enrolled 50 patients with low-risk, hormone-sensitive breast cancer from 2015 to 2018 on a prospective phase 1/2 trial to receive single-fraction, high-gradient partial-breast irradiation (SFHGPBI) 2 to 8 weeks after lumpectomy for node-negative, invasive, or in situ breast cancer. The high gradient was achieved by prescribing 20 Gy to the surgical bed and 5 Gy to the breast tissue within 1 cm of the surgical bed simultaneously in 1 fraction using external beam. RESULTS The median age was 65 (range, 52-84). Ten patients (20%) had small-volume ductal carcinoma in situ while the remainder had stage I disease. At a median follow-up of 25 months, we evaluated toxicity, patient- and physician-reported cosmesis, patient-reported quality of life (QOL), and initial tumor control. There was no Common Terminology Criteria for Adverse Events v4.0 grade 3+ toxicity. Only 34% of patients experienced grade 1 erythema. Good-to-excellent pretreatment cosmesis was present in 100% and 98% per physicians and patients, respectively, and did not change post-SFHGPBI. Quantitative cosmesis by percentage of breast retraction assessment significantly improved over time during the post-SFHGPBI period per mixed repeated measures modeling (P = .0026). QOL per European Organization for Research and Treatment of Cancer QOL Questionnaires C30 and BR-23 did not decline other than temporarily in the systemic therapy effects and hair loss domains, both of which returned to pretreatment values. There was 1 noninvasive in-breast recurrence in a separate untreated quadrant 18 months post-SFHGPBI and 1 isolated axillary recurrence 30 months post-SFHGPBI, both salvaged successfully. There were no distant recurrences or cancer-related deaths observed. CONCLUSIONS Accelerated partial-breast irradiation delivered in a single fraction postoperatively using external beam techniques is a novel, feasible, well-tolerated regimen. SFHGPBI does not adversely affect cosmesis or QOL as reported by both physicians and patients. Initial tumor control rates are excellent, with longer follow-up required to confirm efficacy.

Oncologic Safety and Outcomes in Patients Undergoing Nipple-Sparing Mastectomy. J Am Coll Surg 2020; 230:535-541. [PMID: 32032724 DOI: 10.1016/j.jamcollsurg.2019.12.028] [Citation(s) in RCA: 18] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2019] [Accepted: 12/16/2019] [Indexed: 11/24/2022]
Abstract
BACKGROUND Nipple-sparing mastectomy (NSM) is an alternative to skin-sparing mastectomy in appropriately selected patients. The aim of this study was to review our experience with NSM and to evaluate for oncologic safety. STUDY DESIGN Patients who underwent NSM at our institution from September 2008 through August 2017 were identified after IRB approval. Data included patient age, tobacco use, tumor size, hormone receptor status, lymph node status, radiation and chemotherapy use, incision type, and reconstruction type. Statistical analyses were performed using ANOVA and chi-square tests. RESULTS There were 322 patients who underwent 588 NSM (83% bilateral, 17% unilateral), including 399 (68%) for malignancy (Stage 0 [27%], I [44%], II [25%] and III [4%]). The overall rate of wound complication was 18.9%. Tobacco use increased complication (37.5% vs 16.3%, p < 0.001), as did adjuvant radiation therapy (31.4% vs 17.4%, p = 0.014). Patients with lymph node involvement and larger tumor size had a higher rate of complication (31.3% vs 17.2%, p = 0.016). Patients undergoing circumareolar incisions had a higher rate of complication than those undergoing lateral radial, inframammary fold, or curvilinear incisions (43.5% vs 17.4% vs 17.4% vs 14.3%, respectively, p = 0.018). Six (1%) local chest wall recurrences occurred during the follow-up period, none of which involved the nipple-areolar complex. Four patients (1%) suffered a distant recurrence. CONCLUSIONS Most NSM performed at our institution are in patients with malignancy. The oncologic safety is confirmed by the low locoregional recurrence rate. Tobacco use and adjuvant radiation therapy remain the most significant risk factors for complication, highlighting the need for careful patient selection and patient counseling regarding modifiable risk factors and expected outcomes.

Abstract
BACKGROUND Triple negative breast cancer (TNBC) has worse prognosis than other subtypes of breast cancer, and many patients develop brain metastasis (BM). We developed a simple predictive model to stratify the risk of BM in TNBC patients receiving neo-adjuvant chemotherapy (NAC), surgery, and radiation therapy (RT). METHODS Patients with TNBC who received NAC, surgery, and RT were included. Cox proportional hazards method was used to evaluate factors associated with BM. Significant factors predictive for BM on multivariate analysis (MVA) were used to develop a risk score. Patients were divided into three risk groups: low, intermediate, and high. A receiver operating characteristic (ROC) curve was drawn to evaluate the value of the risk group in predicting BM. This predictive model was externally validated. RESULTS A total of 160 patients were included. The median follow-up was 47.4 months. The median age at diagnosis was 49.9 years. The 2-year freedom from BM was 90.5%. Persistent lymph node positivity, HR 8.75 (1.76-43.52, P = 0.01), and lack of downstaging, HR 3.46 (1.03-11.62, P = 0.04), were significant predictors for BM. The 2-year rate of BM was 0%, 10.7%, and 30.3% (P < 0.001) in patients belonging to low-, intermediate-, and high-risk groups, respectively. Area under the ROC curve was 0.81 (P < 0.001). This model was externally validated (C-index = 0.79). CONCLUSIONS Lack of downstaging and persistent lymph node positivity after NAC are associated with development of BM in TNBC. This model can be used by the clinicians to stratify patients into the three risk groups to identify those at increased risk of developing BM and potentially impact surveillance strategies.

Abstract
Background: The NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) recommend that patients with clinical stage I/II breast cancer undergo advanced imaging for staging only when symptomatic. Regardless, many asymptomatic patients undergo chest CT. The goal of this study was to assess the use and results of chest CT in these patients at an NCCN Member Institution. Methods: Patients with breast cancer diagnosed between 1998 and 2012 were identified in a prospectively maintained database. All patients with clinical stage I/II disease who did not receive neoadjuvant chemotherapy were included. Data collected included demographics, tumor size, node status, chest CT within 6 months of diagnosis, imaging findings, need for additional workup, and identification of metastatic disease. Appropriate statistical tests were used for analysis. Results: From 1998 to 2012, 3,321 patients were diagnosed with early-stage breast cancer. Of these, 2,062 (62.1%) had clinical stage I breast cancer at diagnosis and 1,259 (37.9%) had stage II; 227 patients (11%) with stage I and 456 (36.2%) with stage II breast cancer received staging chest CT. Of patients undergoing CT, 184 (26.9%) were found to have pulmonary nodules, which measured ≤5 mm for 128 patients (69.6%), 5 to 10 mm for 46 patients (25.0%), 11 to 20 mm for 6 patients (3.2%), and ≥20 mm for 4 patients (2.2%). Patients undergoing chest CT for staging subsequently underwent a mean of 2.34 (range, 0-16) additional CTs in follow-up. Of all patients undergoing chest CT for staging, only 9 (1.3%) were ultimately diagnosed with pulmonary metastases at an average of 25 months (range, 0-97) after initial staging chest CT. Conclusions: A significant percentage of patients with stage I/II breast cancer underwent unnecessary chest CT as part of their initial workup. Nearly one-third of these patients were found to have pulmonary nodules, but only 1.3% were ever diagnosed with pulmonary metastases. Adherence to NCCN Guidelines will reduce the excessive use of CT chest imaging.

Abstract
BACKGROUND The Society of Surgical Oncology and American Society of Radiation Oncology consensus statement was the first professional guideline in breast oncology to declare "no ink on tumor" as a negative margin in patients with stages I/II breast cancer undergoing breast-conservation therapy. We sought to analyze the financial impact of this guideline at our institution using a historic cohort. STUDY DESIGN We identified women undergoing re-excision after breast-conserving surgery for invasive breast cancer from 2010 through 2013 using a prospectively maintained institutional database. Clinical and billing data were extracted from the medical record and from administrative resources using CPT codes. Descriptive statistics were used in data analysis. RESULTS Of 254 women in the study population, 238 (93.7%) had stage I/II disease and 182 (71.7%) had invasive disease with ductal carcinoma in situ. A subcohort of 83 patients (32.7%) who underwent breast-conservation therapy for stage I/II disease without neoadjuvant chemotherapy had negative margins after the index procedure, per the Society of Surgical Oncology and American Society of Radiation Oncology guideline. The majority had invasive ductal carcinoma (n = 70 [84.3%]) and had invasive disease (n = 45 [54.2%]), and/or ductal carcinoma in situ (n = 49 [59.0%]) within 1 mm of the specimen margin. Seventy-nine patients underwent 1 re-excision and 4 patients underwent 2 re-excisions, accounting for 81 hours of operative time. Considering facility fees and primary surgeon billing alone, the overall estimated cost reduction would have been $195,919, or $2,360 per affected patient, under the guideline recommendations. CONCLUSIONS Implementation of the Society of Surgical Oncology and American Society of Radiation Oncology consensus guideline holds great potential to optimize resource use. Application of the guideline to a retrospective cohort at our institution would have decreased the overall re-excision rate by 5.6% and reduced costs by nearly $200,000. Additional analysis of patient outcomes and margin assessment methods is needed to define the long-term impact on surgical practice.

Successful Completion of the Pilot Phase of a Randomized Controlled Trial Comparing Sentinel Lymph Node Biopsy to No Further Axillary Staging in Patients with Clinical T1-T2 N0 Breast Cancer and Normal Axillary Ultrasound. J Am Coll Surg 2016; 223:399-407. [PMID: 27212005 DOI: 10.1016/j.jamcollsurg.2016.04.048] [Citation(s) in RCA: 26] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2016] [Revised: 04/21/2016] [Accepted: 04/21/2016] [Indexed: 12/19/2022]
Abstract
BACKGROUND Axillary surgery is not considered therapeutic in patients with clinical T1-T2 N0 breast cancer. The importance of axillary staging is eroding in an era in which tumor biology, as defined by biomarker and gene expression profile, is increasingly important in medical decision making. We hypothesized that axillary ultrasound (AUS) is a noninvasive alternative to sentinel lymph node biopsy (SLNB), and AUS could replace SLNB without compromising patient care. STUDY DESIGN Patients with clinical T1-T2 N0 breast cancer and normal AUS were eligible for enrollment. Subjects were randomized to no further axillary staging (arm 1) vs SLNB (arm 2). Descriptive statistics were used to describe the results of the pilot phase of the randomized controlled trial. RESULTS Sixty-eight subjects were enrolled in the pilot phase of the trial (34 subjects in arm 1, no further staging; 32 subjects in arm 2, SLNB; and 2 subjects voluntarily withdrew from the trial). The median age was 61 years (range 40 to 80 years) in arm 1 and 59 years (range 31 to 81 years) in arm 2, and there were no significant clinical or pathologic differences between the arms. Median follow-up was 17 months (range 1 to 32 months). The negative predictive value (NPV) of AUS for identification of clinically significant axillary disease (>2.0 mm) was 96.9%. No axillary recurrences have been observed in either arm. CONCLUSIONS Successful completion of the pilot phase of the randomized controlled trial confirms the feasibility of the study design, and provides prospective evidence supporting the ability of AUS to exclude clinically significant disease in the axilla. The results provide strong support for a phase 2 randomized controlled trial.

Abstract
SUMMARY Axillary lymph node dissection was used to treat and to provide staging information for women with invasive breast cancer. With the adoption of sentinel lymph node biopsy over the past two decades, evaluation and management of the axilla has become less invasive for many patients. However, as treatment decisions are more frequently based on tumor biology rather than anatomic staging information, the information obtained from even more minimal axillary surgery may be less clinically relevant, and any surgery may cause morbidity. Imaging technologies, such as axillary ultrasound, offer the capability of providing some staging information without the risks associated with surgery. In addition, the therapeutic need for axillary surgery is in question, and less invasive means of managing the axilla are under investigation.

A prospective longitudinal clinical trial evaluating quality of life after breast-conserving surgery and high-dose-rate interstitial brachytherapy for early-stage breast cancer. Int J Radiat Oncol Biol Phys 2013; 87:1043-50.

Abstract
PURPOSE To prospectively examine quality of life (QOL) of patients with early stage breast cancer treated with accelerated partial breast irradiation (APBI) using high-dose-rate (HDR) interstitial brachytherapy. METHODS AND MATERIALS Between March 2004 and December 2008, 151 patients with early stage breast cancer were enrolled in a phase 2 prospective clinical trial. Eligible patients included those with Tis-T2 tumors measuring ≤3 cm excised with negative surgical margins and with no nodal involvement. Patients received 3.4 Gy twice daily to a total dose of 34 Gy. QOL was measured using European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30, version 3.0, and QLQ-BR23 questionnaires. The QLQ-C30 and QLQ-BR23 questionnaires were evaluated during pretreatment and then at 6 to 8 weeks, 3 to 4 months, 6 to 8 months, and 1 and 2 years after treatment. RESULTS The median follow-up was 55 months. Breast symptom scores remained stable in the months after treatment, and they significantly improved 6 to 8 months after treatment. Scores for emotional functioning, social functioning, and future perspective showed significant improvement 2 years after treatment. Symptomatic fat necrosis was associated with several changes in QOL, including increased pain, breast symptoms, systemic treatment side effects, dyspnea, and fatigue, as well as decreased role functioning, emotional functioning, and social functioning. CONCLUSIONS HDR multicatheter interstitial brachytherapy was well tolerated, with no significant detrimental effect on measured QOL scales/items through 2 years of follow-up. Compared to pretreatment scores, there was improvement in breast symptoms, emotional functioning, social functioning, and future perspective 2 years after treatment.

Abstract
The incidence of breast cancer has been on the rise in the United States over the past several decades. The advanced longevity of the population during this same time period, specifically of elderly women, translates to increases in the absolute number of women diagnosed with breast cancer yearly. This, in combination with decreasing mortality rates, has now led to an increase in the number of breast cancer survivors who need long-term follow-up. There has been significant debate over what tests should be obtained, how often they should be obtained, how long surveillance should be continued, and by whom this should be performed. We review the published guidelines for surveillance, available data regarding low- versus high-intensity surveillance plans, current practice patterns, and recommendations for future strategies.

Abstract
Breast-conserving surgery with lumpectomy and adjuvant radiation is the treatment of choice for the majority of early-stage breast cancers. The goals of surgery are to remove the tumor with adequate margins while maintaining an excellent cosmetic outcome. Multiple factors have been associated with higher local recurrence rates, including positive surgical margins. For most nonpalpable breast cancers, needle localization is considered the gold standard for tumor localization when performing lumpectomies. By contrast, palpable breast cancers have historically been excised to grossly negative margins based on palpation alone, which may lead to higher positive margin rates. As a result, ultrasound has been proposed as a tool for intraoperative guidance in the surgical excision of palpable masses. The trial under discussion is a randomized study demonstrating that the use of ultrasound intraoperatively to guide breast conservation surgery decreases the rate of positive margins and the volume of excised tissue, potentially allowing for a better cosmetic outcome.

Positive margin rates following breast-conserving surgery for stage I-III breast cancer: palpable versus nonpalpable tumors. J Surg Res 2012; 177:109-15.

Abstract
BACKGROUND Margin status is a significant risk factor for local recurrence. We sought to examine whether the method of tumor localization predicted the margin status and the need for re-excision for both nonpalpable and palpable breast cancer. METHODS We identified 358 consecutive breast cancer patients who were treated with breast-conserving therapy (BCT) from 1999 to 2006. Data included patient and tumor characteristics, method of localization (needle versus palpation), and pathologic outcomes. Descriptive statistics were used for data summary and data were compared using χ(2). RESULTS Of 358 patients undergoing BCT, 234 (65%) underwent needle localization for a nonpalpable tumor and 124 (35%) underwent a palpation-guided procedure. Patients undergoing palpation-guided procedures were younger and had larger tumors at a more advanced pathologic stage of disease than those undergoing needle localization procedures (P < 0.05 for each). Patient race, tumor grade, presence of lymphovascular invasion, biomarker profile, and nodal status were not significantly different between the two groups (P > 0.05). Overall, 137 patients (38%) had one or more positive margins: 90 of 234 (38%) who had a needle localization procedure and 47 of 124 (38%) who had a palpation-guided procedure (P > 0.05). The number of margins affected did not differ significantly between the two groups. CONCLUSION Although patients with palpable breast cancer had larger tumors than those with nonpalpable breast cancer, the incidence and number of positive margins was similar to those who had needle localization for nonpalpable tumors. Improved methods of localization are needed to reduce the rate of positive margins and the need for re-excision.

Abstract
BACKGROUND We investigated factors associated with positive margins following mastectomy and the impact on outcomes. METHODS We identified 240 patients with stage I-III invasive breast cancer who underwent mastectomy from 1999 to 2009. Data included patient and tumor characteristics, pathologic margin assessment, and outcomes. Margin positivity was defined as the presence of in situ or invasive malignancy at any margin. Descriptive statistics were used for data summary and were compared using χ(2). RESULTS Of the 240 patients, 132 (55%) had a simple mastectomy with sentinel lymph node biopsy and 108 (45%) had a modified radical mastectomy. Overall, 21 patients (9%) had positive margins, including 12 (57%) with one positive margin, 3 (14%) with two positive margins, and 6 (29%) with three or more positive margins. The most commonly affected margin was the deep margin (48% of patients). Eight of the 21 patients (38%) received adjuvant chest wall irradiation. There were no differences between patients who had a positive margin and those who did not with respect to patient age, race, percentage of in situ component, tumor size, tumor grade, lymphovascular invasion, or immunostain profile (P > 0.05 for all). None of the patients with positive margins experienced a local recurrence. CONCLUSIONS Positive margins following mastectomy occurred in nearly 10% of our patients. No specific patient or tumor characteristics predicted a risk for having a positive margin. Despite the finding that only approximately 40% of patients received adjuvant radiation in the setting of a positive margin, no local recurrences have been observed.

Abstract
BACKGROUND We sought to determine the re-excision rate following lumpectomy for palpable breast cancers using intraoperative ultrasound (US). A secondary aim was to investigate the impact on surgical decision-making. METHODS We identified 73 women who underwent US-guided lumpectomy for palpable breast cancer between 2006 and 2010. A cohort of 124 women who underwent palpation-guided lumpectomy was used for a comparison group. Data included patient demographics, tumor characteristics, intraoperative findings, and pathologic outcomes. Descriptive statistics were used for data summary and compared by chi-square or t test, as appropriate. RESULTS A total of 73 women underwent US-guided lumpectomy, and 124 women underwent palpation-guided lumpectomy (median age 55 years). Patients undergoing palpation-guided lumpectomy had smaller tumors that were more likely to be HER2/neu amplified compared with patients undergoing US-guided lumpectomy (P < 0.05 for each). There were no differences between the 2 groups with respect to patient age, tumor grade, and estrogen/progesterone receptor status (P > 0.05 for each). Re-excision rates were similar in both groups [17 (23%) in the US group versus 31 (25%) in the palpation group; P > 0.05]. In the US group, 45 patients (62%) had additional shave margins taken based on US interrogation of the specimen, and 12 patients (16%) were spared a 2nd procedure based on the use of intraoperative US. CONCLUSIONS Although palpable breast cancers can be excised based on direct palpation or needle localization, we believe that US guidance provides an excellent tool to aid the breast surgeon. Only 10% of patients had a positive margin on final pathology as a result, and the overall re-excision rate was acceptable.

Abstract
OBJECTIVES The study was designed to determine which histological lesions produce cellular atypia in lavage specimens and whether ductoscopy adds useful information for the evaluation of high-risk patients with atypical lavage cytology. METHODS We prospectively recruited women ≥35 years at high risk for developing breast cancer. All underwent ductal lavage. Women found to have atypia underwent ductoscopy-directed duct excision (group 1). Women without atypia were observed (group 2). Data included patient demographics, risk assessment, cytologic and histologic findings, and outcomes. Descriptive statistics were utilized for data summary and were compared using Fisher's exact test. RESULTS We enrolled 102 women; 93 (91%) were Caucasian. Their median age was 49 (range 34-73) years with a median follow-up of 80 (range 5-90) months. Overall, 27 (26%) had atypical lavage cytology (group 1), and 75 (74%) had benign cytology (group 2). Subsequent duct excision in group 1 revealed benign histology in 11 (44%), papillomas in 9 (36%), atypical hyperplasia (AH) in 4 (16%), and ductal carcinoma in situ (DCIS) in 1 (4%). At follow-up, three patients developed breast cancer, including one group 1 patient and two group 2 patients. There were no differences between groups 1 and 2 according to patient demographics, Gail scores, or risk for subsequent breast cancer (P > 0.05). CONCLUSIONS Although 20% of high-risk women with ductal lavage atypia have AH or malignancy on subsequent excision, the majority do not. Atypia identified by ductal lavage is not associated with a higher risk of developing subsequent breast cancer, even in this high-risk population.

Are we overtreating papillomas diagnosed on core needle biopsy? Ann Surg Oncol 2010; 18:946-51.

Abstract
BACKGROUND Breast papillomas often are diagnosed with core needle biopsy (CNB). Most studies support excision for atypical papillomas, because as many as one half will be upgraded to malignancy on final pathology. The literature is less clear on the management of papillomas without atypia on CNB. Our goal was to determine factors associated with pathology upgrade on excision. METHODS Our pathology database was searched for breast papillomas diagnosed by CNB during the past 10 years. We identified 277 charts and excluded lesions associated with atypia or malignancy on CNB. Two groups were identified: papillomas that were surgically excised (group 1) and those that were not (group 2). Charts were reviewed for the subsequent diagnosis of cancer or high-risk lesions. Appropriate statistical tests were used to analyze the data. RESULTS A total of 193 papillomas were identified. Eighty-two lesions were excised (42%). Caucasian women were more likely to undergo excision (p = 0.03). Twelve percent of excised lesions were upgraded to malignancy. Increasing age was a predictor of upgrading, but this was not significant. Clinical presentation, lesion location, biopsy technique, and breast cancer history were not associated with pathology upgrade. Two lesions in group 2 ultimately required excision due to enlargement, and both were upgraded to malignancy. CONCLUSIONS Twenty-four percent of papillomas diagnosed on CNB have upgraded pathology on excision--half to malignancy. All of the cancers diagnosed were stage 0 or I. For patients in whom excision was not performed, 2 of 111 papillomas were later excised and upgraded to malignancy.
