RESUMO

BACKGROUND: Targeted axillary dissection (TAD) involves sentinel lymph node biopsy (SLNB) and excision of a biopsy-proven node marked by a clip. This study evaluates the feasibility of non-radioactive wireless localizers for targeted excision of clipped axillary lymph nodes. METHODS: We identified biopsy-proven, node-positive breast cancer patients treated with neoadjuvant therapy (NAT) and TAD from 2016 to 2020, and included those with a clipped node localized using SAVI SCOUT, Magseed, or RFID Tag. Primary outcome measures were (1) successful localization (ultrasound or mammographic-guided placement < 10 mm from target), and (2) retrieval of the clipped node during TAD, documented by specimen radiography or gross visualization. Secondary outcomes included rates of completion axillary lymph node dissection (cALND) and complications. RESULTS: Overall, 57 patients were included; 1 (1.8%) patient had no clip visible at the time of localization, and no radiographic confirmation of clip placement at the time of biopsy, and was therefore excluded. In the remaining 56 patients, localization was successful in 53 (94.6%) patients and the clipped node was retrieved during TAD in 51 (91.1%) patients. Twenty-three of 27 (85.2%) ypN0 patients were spared cALND; 3 (11.1%) patients had cALND for failed clipped node retrieval during TAD, and 1 (3.7%) for false-positive frozen section. In patients with TAD alone, the rates of axillary seroma and infection were 20.0% and 8.6%, respectively. CONCLUSIONS: Wireless non-radioactive localizers are feasible for axillary localization after NAT, with high success rates of retrieving clipped nodes. The lack of signal decay is an advantage of these devices, allowing flexibility in timing of placement.

RESUMO

PURPOSE: We sought to determine whether smartphone GPS data uncovered differences in recovery after breast-conserving surgery (BCS) and mastectomy, and how these data aligned with self-reported quality of life (QoL). METHODS: In a prospective pilot study, adult smartphone-owners undergoing breast surgery downloaded an application that continuously collected smartphone GPS data for 1 week preoperatively and 6 months postoperatively. QoL was assessed with the Short-Form-36 (SF36) via smartphone delivery preoperatively and 4 and 12 weeks postoperatively. Endpoints were trends in daily GPS-derived distance traveled and home time, as well as SF36 Physical (PCS) and Mental Component Scores (MCS) comparing BCS and mastectomy patients. RESULTS: Thirty-one patients were included. Sixteen BCS and fifteen mastectomy patients were followed for a mean of 201 (SD 161) and 174 (107) days, respectively. There were no baseline differences in demographics, PCS/MCS, home time, or distance traveled. Through 12 weeks postoperatively, mastectomy patients spent more time at home [e.g., week 4: 16.7 h 95% CI (14.3, 19.6) vs. 11.0 h (9.4, 12.9), p < 0.001] and traveled shorter distances [e.g., week 4: 52.5 km 95% CI (36.1, 76.0) vs. 107.7 km (75.8-152.9), p = 0.009] compared with BCS patients. There were no significant QoL differences throughout the study as measured by the MCS [e.g., week 4 difference: 7.83 95% CI (- 9.02, 24.7), p = 0.362] or PCS [e.g., week 4 difference: 8.14 (- 6.67, 22.9), p = 0.281]. GPS and QoL trends were uncorrelated (ρ < ± 0.26, p > 0.05). CONCLUSIONS: Differences in BCS and mastectomy recovery were successfully captured using smartphone GPS data. These data may describe currently unmeasured aspects of physical and mental recovery, which could supplement traditional and QoL outcomes to inform shared decision-making.

RESUMO

PURPOSE: To independently evaluate the impact of axillary surgery type and regional lymph node radiation (RLNR) on breast cancer-related lymphedema (BCRL) rates in patients with breast cancer. PATIENTS AND METHODS: From 2005 to 2018, 1,815 patients with invasive breast cancer were enrolled in a lymphedema screening trial. Patients were divided into the following 4 groups according to axillary surgery approach: sentinel lymph node biopsy (SLNB) alone, SLNB+RLNR, axillary lymph node dissection (ALND) alone, and ALND+RLNR. A perometer was used to objectively assess limb volume. All patients received baseline preoperative and follow-up measurements after treatment. Lymphedema was defined as a ≥ 10% relative increase in arm volume arising > 3 months postoperatively. The primary end point was the BCRL rate across the groups. Secondary end points were 5-year locoregional control and disease-free-survival. RESULTS: The cohort included 1,340 patients with SLNB alone, 121 with SLNB+RLNR, 91 with ALND alone, and 263 with ALND+RLNR. The overall median follow-up time after diagnosis was 52.7 months for the entire cohort. The 5-year cumulative incidence rates of BCRL were 30.1%, 24.9%, 10.7%, and 8.0% for ALND+RLNR, ALND alone, SLNB+RLNR, and SLNB alone, respectively. Multivariable Cox models adjusted for age, body mass index, surgery, and reconstruction type showed that the ALND-alone group had a significantly higher BCRL risk (hazard ratio [HR], 2.66; P = .02) compared with the SLNB+RLNR group. There was no significant difference in BCRL risk between the ALND+RLNR and ALND-alone groups (HR, 1.20; P = .49) and between the SLNB-alone and SLNB+RLNR groups (HR, 1.33; P = .44). The 5-year locoregional control rates were similar for the ALND+RLNR, ALND-alone, SLNB+RLNR, and SLNB-alone groups (2.8%, 3.8%, 0%, and 2.3%, respectively). CONCLUSION: Although RLNR adds to the risk of lymphedema, the main risk factor is the type of axillary surgery used.

RESUMO

PURPOSE: During the COVID-19 pandemic, most breast surgery for benign and malignant conditions has been postponed, creating a backlog of patients who will need surgery. A fair and transparent system for assessing the risk of further delaying surgery for individual patients to prioritize surgical scheduling is needed. METHODS: Factors related to risk of delaying surgery for breast patients were identified. Scores were assigned to each factor, with higher scores indicating a greater risk from delaying surgery. REDCap and Microsoft Excel tools were designed to track and score delayed patients. RESULTS: Published data and multidisciplinary clinical judgement were used to assign risk scores based on patient and tumor factors, length of delay, and tumor response to preoperative therapy. Patients completing neoadjuvant chemotherapy were assigned the highest scores as their options for delaying surgery are most limited. Among patients receiving neoadjuvant endocrine therapy or no medical therapy, higher scores were assigned for low-estrogen receptor or high-genomic risk scores, higher grade, larger tumors, younger age and longer delay. High priority scores were assigned for progression during preoperative therapy. Low scores were assigned for re-excisions, atypical lesions and other benign indications. There was good agreement of the tool's ranking of sample patients with rankings by experienced clinicians. The tool generates risk-stratified patient lists by surgeon or institution to facilitate assignment of surgery dates. CONCLUSIONS: This tool generates a clinically consistent, risk-stratified priority list of breast surgical procedures delayed by the COVID-19 pandemic. This systematic approach may facilitate surgical scheduling as conditions normalize.

RESUMO

BACKGROUND: Clinical trials are currently ongoing to determine the safety and efficacy of active surveillance (AS) versus usual care (surgical and radiation treatment) for women with ductal carcinoma in situ (DCIS). This study aimed to determine upgrade rates of DCIS at needle biopsy to invasive carcinoma at surgery among women who meet the eligibility criteria for AS trials. METHODS: A retrospective review was performed of consecutive women at an academic medical center with a diagnosis of DCIS at needle biopsy from 2007 to 2016. Medical records were reviewed for mode of presentation, imaging findings, biopsy pathology results, and surgical outcomes. Each patient with DCIS was evaluated for AS trial eligibility based on published criteria for the COMET, LORD, and LORIS trials. RESULTS: During a 10-year period, DCIS was diagnosed in 858 women (mean age 58 years; range 28-89 years). Of the 858 women, 498 (58%) were eligible for the COMET trial, 101 (11.8%) for the LORD trial, and 343 (40%) for the LORIS trial. The rates of upgrade to invasive carcinoma were 12% (60/498) for the COMET trial, 5% (5/101) for the LORD trial, and 11.1% (38/343) for the LORIS trial. The invasive carcinomas ranged from 0.2 to 20 mm, and all were node-negative. CONCLUSIONS: Women who meet the eligibility criteria for DCIS AS trials remain at risk for occult invasive carcinoma at presentation, with upgrade rates ranging from 5 to 12%. These findings suggest that more precise criteria are needed to ensure that women with invasive carcinoma are excluded from AS trials.

RESUMO

Tele-education is the use of communications technologies to distribute knowledge from one health care provider to another when distance separates providers. At the University of Arkansas for Medical Sciences, tele-education has been used for more than two decades to educate and support rural obstetrician/gynecologists throughout the state. Tele-education at University of Arkansas for Medical Sciences incorporates numerous interactive videoconferences and other digital portals and platforms. Continued provider education through tele-education increases access to quality care and evidenced-based practices for rural populations and is an effective strategy in the battle against health care disparities.

RESUMO

PURPOSE: While various studies have highlighted the prognostic significance of pathologic complete response (pCR) after neoadjuvant chemotherapy (NAT), the impact of additional adjuvant therapy after pCR is not known. EXPERIMENTAL DESIGN: PubMed was searched for studies with NAT for breast cancer and individual patient-level data was extracted for analysis using plot digitizer software. HRs, with 95% probability intervals (PI), measuring the association between pCR and overall survival (OS) or event-free survival (EFS), were estimated using Bayesian piece-wise exponential proportional hazards hierarchical models including pCR as predictor. RESULTS: Overall, 52 of 3,209 publications met inclusion criteria, totaling 27,895 patients. Patients with a pCR after NAT had significantly better EFS (HR = 0.31; 95% PI, 0.24-0.39), particularly for triple-negative (HR = 0.18; 95% PI, 0.10-0.31) and HER2+ (HR = 0.32; 95% PI, 0.21-0.47) disease. Similarly, pCR after NAT was also associated with improved survival (HR = 0.22; 95% PI, 0.15-0.30). The association of pCR with improved EFS was similar among patients who received subsequent adjuvant chemotherapy (HR = 0.36; 95% PI, 0.19-0.67) and those without adjuvant chemotherapy (HR = 0.36; 95% PI, 0.27-0.54), with no significant difference between the two groups (P = 0.60). CONCLUSIONS: Achieving pCR following NAT is associated with significantly better EFS and OS, particularly for triple-negative and HER2+ breast cancer. The similar outcomes with or without adjuvant chemotherapy in patients who attain pCR likely reflects tumor biology and systemic clearance of micrometastatic disease, highlighting the potential of escalation/deescalation strategies in the adjuvant setting based on neoadjuvant response.See related commentary by Esserman, p. 2771.

RESUMO

BACKGROUND: Obtaining tumor-free margins is critical to prevent recurrence after lumpectomy for breast cancer. Unfortunately, current approaches leave positive margins that require second surgeries in 20-40% of patients. We assessed the LUM Imaging System for real-time, intraoperative detection of residual tumor. METHODS: Breast lumpectomy cavity walls and excised specimens were assessed with the LUM Imaging System after 1 mg/kg intravenous LUM015, a protease-activatable fluorescent agent. Fluorescence at potential sites of residual tumor in lumpectomy cavity walls was evaluated intraoperatively with a sterile hand-held probe, with real-time predictive results displayed on a monitor intraoperatively, and later correlated with histopathology. RESULTS: In vivo lumpectomy cavities and excised specimens were imaged after LUM015 injection in 45 women undergoing breast cancer surgery. Invasive ductal and lobular cancers and intraductal cancer (DCIS) were included. A total of 570 cavity margin surfaces in 40 patients were used for algorithm development. Image analysis and display took approximately 1 s per 2.6-cm-diameter circular margin surface. All breast cancer subtypes could be distinguished from adjacent normal tissue. For all imaged cavity surfaces, sensitivity for tumor detection was 84%. Among 8 patients with positive margins after standard surgery, sensitivity for residual tumor detection was 100%; 2 of 8 were spared second surgeries because additional tissue was excised at sites of LUM015 signal. Specificity was 73%, with some benign tissues showing elevated fluorescent signal. CONCLUSIONS: The LUM015 agent and LUM Imaging System allow rapid identification of residual tumor in the lumpectomy cavity of breast cancer patients and may reduce rates of positive margins.

RESUMO

BACKGROUND: We previously reported that breast conservation was feasible for women with large or irregularly shaped breast cancers when tumor resection was guided by multiple localizing wires. We now report long-term outcomes of multiple-wire versus single-wire localized lumpectomies for breast cancer. PATIENTS AND METHODS: We retrospectively reviewed wire-localized lumpectomies at our institution from May 2000 to November 2006. Rates of ipsilateral in-breast tumor recurrence, metastasis, and subsequent unplanned diagnostic imaging and biopsy were compared between multiple-wire and single-wire cohorts. RESULTS: We identified 112 multiple-wire and 160 single-wire breast cancer lumpectomies that achieved clear margins. Median age was 64 years in the multiple-wire cohort and 57 years in the single-wire cohort. Mean lumpectomy volume was 75 mL in multiple-wire patients and 49 mL in single-wire patients (P = .003). Invasive tumor size, axillary node status, and use of radiation and systemic therapy were similar, but the multiple-wire group had more patients with ductal carcinoma-in-situ only (38% vs. 28%). At 108 months' median follow-up, there was no significant difference in local or distant recurrence rates between multiple-wire and single-wire cohorts. Six (5%) multiple-wire patients and 6 (4%) single-wire patients had local recurrences and 3 (3%) multiple-wire and 5 (3%) single-wire patients developed metastatic disease. Unplanned diagnostic imaging was required for 53 (47%) multiple-wire and 65 (41%) single-wire patients. Subsequent ipsilateral biopsy occurred in 15 (13%) multiple-wire and 19 (12%) single-wire patients. CONCLUSION: Breast-conserving surgery with multiple localizing wires is a safe alternative to mastectomy for breast cancer patients with large mammographic lesions.

RESUMO

OBJECTIVES: This study evaluates complications and reconstructive failure rates in implant-based reconstruction with radiotherapy. BACKGROUND: Postmastectomy radiotherapy may adversely affect breast reconstructive outcomes. However, the comparative effect of radiotherapy on direct-to-implant versus tissue expander-implant reconstruction has not been examined. METHODS: Single institution retrospective review was performed and patients were followed 2 to 10 years. RESULTS: Of 1566 patients, 265 patients received radiation (149 immediate implants and 116 tissue expanders). Demographics were similar except more smokers in the expander group (7.7% vs 1.3%; P = 0.012). Patients who received radiation with an expander in place had overall more complications (32.8% vs 11.4%; P < 0.001), skin necrosis (10.3% vs 4.0%; P = 0.043), wound breakdown (9.5% vs 2.7%; P = 0.029), and infections (16.4% vs 4.03%; P = 0.001) leading to a higher rate of explantation (16.4% vs 4.0%; P < 0.001). A radiation boost likewise predicted complications [odds ratio (OR) 2.199, 95% confidence interval (CI) 1.154-4.188, P = 0.017]. When comparing reconstructive outcomes, radiated expanders had a higher failure rate (21.6% vs 11.4%; P = 0.025). Revision for capsular contracture was similar between the 2 cohorts (11.4% vs 11.2%; P = 0.959) as were revision rates for contour asymmetry and breast asymmetry. In our multivariable logistic regression analysis, radiation to the expander had a higher risk of reconstruction failure than radiation to the permanent implant (OR 2.020, 95% CI 1.010-4.037, P = 0.047). CONCLUSION: Most patients had successful implant-based reconstructions after mastectomy and radiotherapy. Our study showed radiotherapy after direct-to-implant breast reconstruction had a lower rate of complications and reconstructive failure compared to tissue expander-implant reconstruction.

RESUMO

Importance: Patient-generated health data captured from smartphone sensors have the potential to better quantify the physical outcomes of surgery. The ability of these data to discriminate between postoperative trends in physical activity remains unknown. Objective: To assess whether physical activity captured from smartphone accelerometer data can be used to describe postoperative recovery among patients undergoing cancer operations. Design, Setting, and Participants: This prospective observational cohort study was conducted from July 2017 to April 2019 in a single academic tertiary care hospital in the United States. Preoperatively, adults (age ≥18 years) who spoke English and were undergoing elective operations for skin, soft tissue, head, neck, and abdominal cancers were approached. Patients were excluded if they did not own a smartphone. Exposures: Study participants downloaded an application that collected smartphone accelerometer data continuously for 1 week preoperatively and 6 months postoperatively. Main Outcomes and Measures: The primary end points were trends in daily exertional activity and the ability to achieve at least 60 minutes of daily exertional activity after surgery among patients with vs without a clinically significant postoperative event. Postoperative events were defined as complications, emergency department presentations, readmissions, reoperations, and mortality. Results: A total of 139 individuals were approached. In the 62 enrolled patients, who were followed up for a median (interquartile range [IQR]) of 147 (77-179) days, there were no preprocedural differences between patients with vs without a postoperative event. Seventeen patients (27%) experienced a postoperative event. These patients had longer operations than those without a postoperative event (median [IQR], 225 [152-402] minutes vs 107 [68-174] minutes; P < .001), as well as greater blood loss (median [IQR], 200 [35-515] mL vs 25 [5-100] mL; P = .006) and more follow-up visits (median [IQR], 2 [2-4] visits vs 1 [1-2] visits; P = .002). Compared with mean baseline daily exertional activity, patients with a postoperative event had lower activity at week 1 (difference, -41.6 [95% CI, -75.1 to -8.0] minutes; P = .02), week 3 (difference, -40.0 [95% CI, -72.3 to -3.6] minutes; P = .03), week 5 (difference, -39.6 [95% CI, -69.1 to -10.1] minutes; P = .01), and week 6 (difference, -36.2 [95% CI, -64.5 to -7.8] minutes; P = .01) postoperatively. Fewer of these patients were able to achieve 60 minutes of daily exertional activity in the 6 weeks postoperatively (proportions: week 1, 0.40 [95% CI, 0.31-0.49]; P < .001; week 2, 0.49 [95% CI, 0.40-0.58]; P = .003; week 3, 0.39 [95% CI, 0.30-0.48]; P < .001; week 4, 0.47 [95% CI, 0.38-0.57]; P < .001; week 5, 0.51 [95% CI, 0.42-0.60]; P < .001; week 6, 0.73 [95% CI, 0.68-0.79] vs 0.43 [95% CI, 0.33-0.52]; P < .001). Conclusions and Relevance: Smartphone accelerometer data can describe differences in postoperative physical activity among patients with vs without a postoperative event. These data help objectively quantify patient-centered surgical recovery, which have the potential to improve and promote shared decision-making, recovery monitoring, and patient engagement.

RESUMO

PURPOSE: To evaluate the safety and efficacy of proton beam radiation therapy (RT) for patients with breast cancer who require regional nodal irradiation. METHODS: Patients with nonmetastatic breast cancer who required postoperative RT to the breast/chest wall and regional lymphatics and who were considered suboptimal candidates for conventional RT were eligible. The primary end point was the incidence of grade 3 or higher radiation pneumonitis (RP) or any grade 4 toxicity within 3 months of RT. Secondary end points were 5-year locoregional failure, overall survival, and acute and late toxicities per Common Terminology Criteria for Adverse Events (version 4.0). Strain echocardiography and cardiac biomarkers were obtained before and after RT to assess early cardiac changes. RESULTS: Seventy patients completed RT between 2011 and 2016. Median follow-up was 55 months (range, 17 to 82 months). Of 69 evaluable patients, median age was 45 years (range, 24 to 70 years). Sixty-three patients (91%) had left-sided breast cancer, two had bilateral breast cancer, and five had right-sided breast cancer. Sixty-five (94%) had stage II to III breast cancer. Sixty-eight (99%) received systemic chemotherapy. Fifty (72%) underwent immediate reconstruction. Median dose to the chest wall/breast was 49.7 Gy (relative biological effectiveness) and to the internal mammary nodes, 48.8 Gy (relative biological effectiveness), which indicates comprehensive coverage. Among 62 surviving patients, the 5-year rates for locoregional failure and overall survival were 1.5% and 91%, respectively. One patient developed grade 2 RP, and none developed grade 3 RP. No grade 4 toxicities occurred. The unplanned surgical re-intervention rate at 5 years was 33%. No significant changes in echocardiography or cardiac biomarkers after RT were found. CONCLUSION: Proton beam RT for breast cancer has low toxicity rates and similar rates of disease control compared with historical data of conventional RT. No early cardiac changes were observed, which paves the way for randomized studies to compare proton beam RT with standard RT.

RESUMO

BACKGROUND: This study examined the effects of an enhanced recovery program on inpatient opioid requirements and hospital length of stay (LOS) for mastectomy patients undergoing immediate reconstruction. METHODS: An enhanced recovery program for patients undergoing mastectomy with immediate tissue expander (TE) or implant reconstruction was evaluated by comparing a contemporary cohort of 611 patients in 2016-2018 with a historical cohort of 188 patients in 2010. Opioid use and LOS were compared over time and stratified by laterality, mastectomy type, axillary procedure, and reconstruction. Associations were assessed by uni- and multivariate analyses. RESULTS: In 2010, 95.2% of patients required intravenous (IV) opioids, with a last dose 15.5 h after completion of surgery, compared with 68.7% of patients in 2016-2018, with a last dose 1.8 h after surgery (p < 0.001). Patients prescribed gabapentin postoperatively were less likely to require inpatient IV or oral opioids (p < 0.001). The mean LOS decreased from 37 h in 2010 to 27.5 h in 2016-2018 without an increase in the readmission rate (6.9% vs. 4.1%; p = 0.112). Patients were more likely to stay more than one night if they were older (p = 0.012), had undergone bilateral mastectomies (p < 0.001) or TE reconstruction (p = 0.012), and had surgery in 2010 compared with 2016-2018 (p < 0.001). Even after adjustment for LOS, IV opioid use remained significantly associated with year of surgery (p < 0.001). CONCLUSIONS: Compared with 2010, patients undergoing mastectomy with TE or implant reconstruction in 2016-2018 required less inpatient opioids and had decreased LOS. The authors attribute this to an enhanced recovery program focused on preoperative counseling, non-opioid analgesics, and improved surgical efficiencies.

RESUMO

INTRODUCTION: Bilateral reduction mammoplasty is one of the most common plastic surgery procedures performed in the U.S. This study examines the incidence, management, and prognosis of incidental breast cancer identified in reduction specimens from a large cohort of reduction mammoplasty patients. METHODS: Breast pathology reports were retrospectively reviewed for evidence of incidental cancers in bilateral reduction mammoplasty specimens from five institutions between 1990 and 2017. RESULTS: A total of 4804 women met the inclusion criteria of this study; incidental cancer was identified in 45 breasts of 39 (0.8%) patients. Six patients (15%) had bilateral cancer. Overall, the maximum diagnosis by breast was 16 invasive cancers and 29 ductal carcinomas in situs. Thirty-three patients had unilateral cancer, 15 (45.5%) of which had high-risk lesions in the contralateral breast. Twenty-one patients underwent mastectomy (12 bilateral and nine unilateral), residual cancer was found in 10 in 25 (40%) therapeutic mastectomies. Seven patients did not undergo mastectomy received breast radiation. The median follow-up was 92 months. No local recurrences were observed in the patients undergoing mastectomy or radiation. Three of 11 (27%) patients who did not undergo mastectomy or radiation developed a local recurrence. The overall survival rate was 87.2% and disease-free survival was 82.1%. CONCLUSIONS: Patients undergoing reduction mammoplasty for macromastia have a small but definite risk of incidental breast cancer. The high rate of bilateral cancer, contralateral high-risk lesions, and residual disease at mastectomy mandates thorough pathologic evaluation and careful follow-up of these patients. Mastectomy or breast radiation is recommended for local control given the high likelihood of local recurrence without either.

RESUMO

PURPOSE: Giving an additional radiation dose to the incision or chest wall has been a practice, but it has never been studied in a randomized setting, and it might lead to inferior cosmetic outcomes. This study aims to evaluate whether delivery of a chest wall boost (CWB) to the mastectomy scar or chest wall is independently associated with reconstruction complications and to assess its disease control efficacy in the setting of breast reconstruction. METHODS AND MATERIALS: We conducted a retrospective chart review of 746 patients with breast cancer who underwent mastectomy, breast reconstruction, and PMRT; all underwent treatment at our institution during 1997 to 2016. Various reconstruction techniques were used among this cohort including autologous reconstruction, single-stage direct-to-implant reconstruction, and 2-stage tissue expander implant. Cohorts were divided by administration of CWB. The primary objective was comparing the rate of reconstruction complications including skin necrosis, fat necrosis and infection between groups. Subgroup analysis for patients with implant-based reconstruction was performed to evaluate the effect of CWB on implant-related complications such as capsular contracture, implant exposure, and implant failure. The secondary objective was comparison of the cumulative incidence of local failure between groups overall and within clinically high-risk subgroups. RESULTS: The median follow-up was 5.2 years. Most clinicopathologic features were well balanced between the 379 (51%) patients who received CWB and the 367 (49%) who did not. On multivariate analysis, CWB was significantly associated with infection, skin necrosis, and implant exposure. For implant reconstruction patients, CWB independently increased risks of implant failure. CWB administration was not associated with local tumor control benefits, even in high-risk subgroups. CONCLUSIONS: Our findings suggest that omission of chest wall boost in postmastectomy radiation improves breast reconstruction outcomes without compromising local tumor control.

RESUMO

BACKGROUND: Nipple-sparing mastectomies (NSMs) preserve the intact nipple, including nipple duct orifices. Retained orifices might remain patent and communicate with the underlying reconstruction. We report the incidence and outcomes of nipple discharge after NSM in pregnant and nonpregnant women. PATIENTS AND METHODS: Retrospective review of all NSMs at our institution from June 2007 to June 2018 was performed. Subsequent pregnancies and nipple discharge were documented. Patient demographic, operative, histopathology, and cancer treatment data were collected. Descriptive analysis was performed for patients who developed nipple discharge. RESULTS: From June 2007 to June 2018, 2778 NSM procedures were performed in 1620 patients, with a mean age of 48 (range, 20-80) years. Fifteen hundred sixty-eight NSMs were therapeutic and 1210 were for risk reduction. Thirty-three subsequent pregnancies were observed in 27 patients, with a mean age of 33 (range, 26-42) years at NSM. Bilateral or unilateral discharge occurred in 6 of 27 (22%) postpartum patients and resolved spontaneously. At 54 months mean follow-up after NSM (range, 16-98 months) and 23 (range, 1-61) months after delivery, no local-regional recurrences were observed. In 1593 patients without subsequent pregnancy, there were 4 patients (0.25%) treated with bilateral NSM with subsequent unilateral watery nipple discharge. There was no evidence of associated malignancy on physical exam, imaging, or cytology, and with 55 to 110 months follow-up, no new or recurrent cancers have been observed. CONCLUSION: Despite extensive removal of nipple and subareolar duct tissue during NSM, milky nipple discharge is possible postpartum. Watery, acellular discharge occurs rarely in nonpregnant patients. To date, no patient with discharge has developed a local recurrence or new breast cancer.

RESUMO

The use of contralateral prophylactic mastectomy (CPM) is increasing among breast cancer patients who are at average or "sporadic" risk for contralateral breast cancer. Because CPM provides no survival benefit for these patients, it is not medically recommended for them. Decision support aids may facilitate more informed, higher quality CPM decision. The purpose of this study was to evaluate the feasibility and acceptability of B-Sure, an online decision support aid to facilitate informed decisions regarding CPM, and to compare the impact of B-Sure in increasing CPM knowledge, reducing decisional conflict, and increasing preparedness to make the CPM decision among breast cancer patients at sporadic risk who are considering CPM. Ninety-three patients with unilateral, nonhereditary breast cancer considering CPM completed a baseline survey, were randomized to receive B-Sure or Usual care, and completed a 4-week follow-up survey assessing decisional conflict, preparedness to make the CPM decision, and CPM knowledge as well as self-efficacy, perceived risk, worry, CPM motivations, and the surgical decision. Study participation was high. B-Sure was viewed by almost 80% of the participants and was evaluated positively. At follow-up, patients assigned to B-Sure reported significantly higher clarity regarding the personal values relevant to the CPM decision and higher knowledge about CPM. B-Sure had smaller effects on other aspects of decisional conflict. B-Sure improved CPM knowledge and reduced decisional conflict. Patients considering CPM may benefit from an online decision support aid, but may be sensitive to approaches that they perceive as biased against CPM.

RESUMO

PURPOSE: Mammoplasty removes random samples of breast tissue from asymptomatic women providing a unique method for evaluating background prevalence of breast pathology in normal population. Our goal was to identify the rate of atypical breast lesions and cancers in women of various ages in the largest mammoplasty cohort reported to date. METHODS: We analyzed pathologic reports from patients undergoing bilateral mammoplasty, using natural language processing algorithm, verified by human review. Patients with a prior history of breast cancer or atypia were excluded. RESULTS: A total of 4775 patients were deemed eligible. Median age was 40 (range 13-86) and was higher in patients with any incidental finding compared to patients with normal reports (52 vs. 39 years, p = 0.0001). Pathological findings were detected in 7.06% (337) of procedures. Benign high-risk lesions were found in 299 patients (6.26%). Invasive carcinoma and ductal carcinoma in situ were detected in 15 (0.31%) and 23 (0.48%) patients, respectively. The rate of atypias and cancers increased with age. CONCLUSION: The overall rate of abnormal findings in asymptomatic patients undergoing mammoplasty was 7.06%, increasing with age. As these results are based on random sample of breast tissue, they likely underestimate the prevalence of abnormal findings in asymptomatic women.
