ABSTRACT
BACKGROUND: The objective of this study was to describe patient values and personality traits associated with breast surgery choice for patients with breast cancer. METHODS: A survey based on qualitative patient interviews and the Big-Five personality trait profile was distributed to Love Research Army volunteers aged 18-70 years old who underwent breast cancer surgery from 2009 to 2020. Multivariable logistic regression analysis was used to determine independent patient values and personality traits for the choice of breast-conserving surgery (BCS), unilateral mastectomy (UM) and bilateral mastectomy (BM). RESULTS: 1497 participants completed the survey. Open-mindedness was associated with UM and sociability was associated with BM. A majority of patients prioritized cancer outcomes. Compared to BM patients, BCS and UM patients were significantly more likely to choose values associated with maintaining their self-image, optimizing surgical recovery, and following their doctor's recommendation. CONCLUSIONS: Other values besides cancer outcomes differentiate patient surgical choice for BCS or mastectomy.

INTRODUCTION: The objective of this study was to examine the impact of the early part of the COVID-19 pandemic on the number of newly diagnosed breast cancer cases at Commission on Cancer (CoC)-accredited facilities relative to the United States (U.S.) population. METHODS: We examined the incidence of breast cancer cases at CoC sites using the U.S. Census population as the denominator. Breast cancer incidence was stratified by patient age, race and ethnicity, and geographic location. RESULTS: A total of 1,499,806 patients with breast cancer were included. For females, breast cancer cases per 100,000 individuals went from 188 in 2015 to 203 in 2019 and then dropped to 176 in 2020 with a 15.7% decrease from 2019 to 2020. Breast cancer cases per 100,000 males went from 1.7 in 2015 to 1.8 in 2019 and then declined to 1.5 in 2020 with a 21.8% decrease from 2019 to 2020. For both females and males, cases per 100,000 individuals decreased from 2019 to 2020 for almost all age groups. For females, rates dropped from 2019 to 2020 for all races and ethnicities and geographic locations. The largest percent change was seen among Hispanic patients (-18.4%) and patients in the Middle Atlantic division (-18.6%). The stage distribution (0-IV) for female and male patients remained stable from 2018 to 2020. CONCLUSION: The first year of the COVID-19 pandemic was associated with a decreased number of newly diagnosed breast cancer cases at Commission on Cancer sites.

BACKGROUND: The American Society of Breast Surgeons released a consensus statement that genetic testing should be made available to all patients with a personal history of breast cancer. However, it is not clear whether physicians feel comfortable with universal genetic testing (UGT) or if they have sufficient knowledge to interpret results and manage them appropriately. OBJECTIVE: The purpose of this study was to explore breast surgeons' attitudes toward UGT. METHODS: Breast surgeons were consented and scheduled for a semi-structured virtual interview. Transcripts were uploaded into qualitative analysis software where they were exhaustively and iteratively coded. Codes were then organized into higher-order categories and themes and data saturation were assessed. RESULTS: Thirty-one surgeons completed the qualitative interview. Most surgeons practiced in the academic or community setting and most practiced in the Midwest (71.0%). The majority (90.3%) reported having a structured genetics program. The majority (96.8%) referred their patients to genetics for counseling and most preferred ordering testing through a genetic services provider. Some surgeons had concerns about access to genetic services. A minority of surgeons order UGT for all newly diagnosed breast cancer patients. The majority of respondents thought that more training in genetics was needed for surgeons. Many surgeons expressed concern about the psychosocial effects of UGT on patients. CONCLUSIONS: Many surgeons expressed concerns about UGT, mainly related to discomfort with their training, access to genetic services, and the psychosocial impact on their patients. Future work is needed to determine how to improve surgeon's comfort level in implementing UGT.

INTRODUCTION: Studies have shown a decrease in bilateral mastectomy (BM) rates over the past five to ten years, but it is not clear if these decreases are the same across different patient races. METHODS: Using the National Cancer Database (NCDB) we examined BM rates for patients with AJCC Stage 0-II unilateral breast cancer from 2004 to 2020 for White versus nonwhite races (Blacks, Hispanics, and Asians). Multivariable logistic regression was used to identify patient and facility factors associated with BM by patient race from 2004 to 2006 and 2018-2020. RESULTS: Of 1,187,864 patients, 791,594 (66.6%) had breast conserving surgery (BCS), 258,588 (21.8%) had unilateral mastectomy (UM) and 137,682 (11.6%) had BM. Our patient population was 927,530 (78.1%) White patients, 124,636 (10.5%) Black patients, 68,048 (5.7%) Hispanic patients, and 48,341 (4.1%) Asian patients. The BM rate steadily increased from 5.6% to 15.6% from 2004 to 2013, at which point the BM rate decreased to 11.3% in 2020. The decrease in BM was seen across all races, and in 2020, 6,487 (11.7%) Whites underwent BM compared to 506 (10.7%) Hispanics, 331 (9.2%) Asians, and 723 (9.1%) Blacks. Race was a significant independent factor for BM in 2004-2006 and 2018-2020 but all races were more likely to undergo BM in 2004 compared to 2020 after adjusting for patient and facility factors. Compared to Whites, the odds of undergoing BM were OR 0.41 (0.37-0.45) in 2004 compared to OR 0.66 (0.63-0.69) in 2020 for Blacks, OR 0.44 (0.38-0.52) and OR 0.61 (0.57-0.65) for Asians and OR 0.59 (0.52-0.66) and OR 0.71 (0.67-0.75) for Hispanics, respectively. CONCLUSION: BM rates for all races have declined since 2013, and differences in rates of BM amongst races have narrowed.

BACKGROUND: The delay of elective surgeries by the coronavirus 2019 (COVID-19) pandemic prompted concern among surgeons to delay estrogen receptor (ER)-negative ductal carcinoma in situ (DCIS) for fear of missing an ER-negative invasive cancer and compromising survival of patients. STUDY DESIGN: Female patients ≥40 years old diagnosed with ER-negative DCIS from 2004 to 2017 were examined from the National Cancer Database. Multivariable logistic regression, adjusting for patient and tumor factors, was used to determine factors associated with tumor upstage. Multivariable Cox proportional hazards modeling was used to determine if surgical delay impacted overall survival of ER-negative DCIS patients that were upstaged to invasive disease. RESULTS: There were 219,731 patients with DCIS of which 24,338 (11.1%) had tumor upstage. Of these patients, 5,675 (16.2%) of ER-negative and 18,663 (10.1%) of ER-positive DCIS patients were upstaged (p ≤ 0.001). From 2004 to 2017, ER-negative DCIS upstage rates increased from 12.9% to 18.9%. Independent factors associated with tumor upstage were younger age (odds ratio [OR] 0.75 [95% CI 0.69 to 0.81]) and Black race (OR 1.34 [95% CI 1.22 to 1.46]). Compared with patients with ≤30 days between biopsy and surgery, patients with a 31- to 60-day interval (OR 1.13 [95% CI 1.05 to 1.20]) and a >60-day interval (OR 1.12 [95% CI 1.02 to 1.23]) had an increased rate of tumor upstage. Among ER-negative DCIS patients whose tumors were upstaged to invasive disease, Cox proportional hazard regression modeling showed no association between the number of days between biopsy and surgery and overall survival. CONCLUSIONS: Delays in surgery were associated with higher tumor upstage rates but not with worse overall survival.

BACKGROUND: Little is known about the experience of the male breast cancer patient. Mastectomy is often offered despite evidence that breast-conserving surgery (BCS) provides similar outcomes. METHODS: Two concurrent online surveys were distributed from August to October 2020 via social media to male breast cancer (MBC) patients and by email to American Society of Breast Surgeon members. The MBC patients were asked their opinions about their surgery, and the surgeons were asked to provide surgical recommendations for MBC patients. RESULTS: The survey involved 63 MBC patients with a mean age of 62 years (range, 31-79 years). Five MBC patients (7.9 %) stated that their surgeon recommended BCS, but 54 (85.7 %) of the patients underwent unilateral, and 8 (12.7 %) underwent bilateral mastectomy. Most of the patients (n = 60, 96.8 %) had no reconstruction. One third of the patients (n = 21, 33.3 %) felt somewhat or very uncomfortable with their appearance after surgery. The response rate was 16.5 % for the surgeons. Of the 438 surgeons who answered the survey, 298 (73.3 %) were female, 215 (51.7 %) were fellowship-trained, and 244 (58.9 %) had been practicing for 16 years or longer. More than half of surgeons (n = 259, 59.1 %) routinely offered BCS to eligible men, and 180 (41.3 %) stated they had performed BCS on a man with breast cancer. Whereas 89 (20.8 %) of the surgeons stated that they routinely offer reconstruction to MBC patients, 87 (20.3 %) said they do not offer reconstruction, 96 (22.4 %) said they offer it only if the patient requests it, and 157 (36.6 %) said they never consider it as an option. CONCLUSIONS: The study found discordance between MBC patients' satisfaction with their surgery and surgeon recommendations and experience. These data present an opportunity to optimize the MBC patient experience.

BACKGROUND: The recent data on decision regret of patients undergoing breast cancer surgery are sparse. METHODS: An electronic cross-sectional survey was distributed to Love Research Army volunteers ages 18-70 years who underwent breast cancer surgery from 2009 to 2020. Decision regret scores were compared among patients who underwent bilateral mastectomy (BM), unilateral mastectomy (UM), breast-conserving surgery (BCS), and BCS first (BCS followed by re-excision or mastectomy) and between procedures during different time periods. Multivariable logistic regression, adjusted for patient and tumor factors, was used to determine whether surgery type was associated with a regret score in the highest quartile range. RESULTS: The survey was completed by 2148 women, 1525 (71.0%) of whom reported their surgery choice and answered all questions on the regret scale. The mean age of the participants was 50 years, and the median year of surgery was 2014. The median decision regret score for all the patients was 5 (interquartile range [IQR], 0-20) on a 100-point scale. The regret score of 342 participants (22.4%) was 25 or higher (BCS, 20.2%; BCS first, 31.9%; UM, 30.8%; BM, 15.4%; p < 0.001). In the multivariable analysis, BM was associated with less regret than UM (odds ratio [OR], 0.40 (range, 0.27-0.58); p < 0.001), BCS (OR, 0.56 (range, 0.38-0.83; p = 0.003), or BCS first (OR, 0.32; range, 0.21-0.49; p < 0.001). During the three periods analyzed (2009-2012, 2013-2016, and 2017-2020), the BM and BCS patients had the lowest regret scores of all the surgical types. CONCLUSIONS: Decision regret was low among the patients undergoing breast cancer surgery but lowest among the BM patients after adjustment for clinical and tumor factors including complications.

BACKGROUND: The objective of this study was to examine whether an exercise program and standardized operating room positioning protocol (EOPP) would improve surgeon muscle workload and/or surgeon perception of mental/physical workload for nipple-sparing mastectomy (NSM). METHODS: This prospective study analyzed muscle workload by EMG of four surgeons performing NSM before and after an EOPP. Surveys were administered assessing surgeon perception of mental/physical workload. EMG data were analyzed using repeated-measures ANOVA, controlling for surgeon, first assistant, duration and difficulty of procedure, left or right side, and sequence of the procedure. RESULTS: A total of 56 NSM cases performed by 3 surgeons were analyzed. One surgeon was excluded because of muscle injury and undergoing active physical therapy during the study period. After implementation of the EOPP, the left (P = 0.005) and right (P = 0.020) upper trapezii muscles had a significant decrease in overall ergonomic workload but there was no significant change in overall ergonomic workload for the bilateral cervical erector spinae, anterior deltoid, and lumbar erector spinae muscle groups. When analyzing muscle group exertion by surgeon, there was significant variability in all muscles except the left cervical erector spinae. Following the EOPP, surgeons reported that the procedures were more physically (P = 0.01) and mentally (P = 0.002) demanding and visualization (P = 0.04) was worse. The breast laterality and sequence did not affect muscle exertion. CONCLUSIONS: An EOPP decreased the overall ergonomic workload of one muscle group for surgeons performing NSM but did not impact surgeon perception of mental/physical workload. Further investigation is needed to improve surgeon ergonomics.

PURPOSE: To examine how treatment delays brought on by the COVID-19 pandemic impacted the physical and emotional well-being of physicians treating these patients. METHODS: A cross-sectional survey of physician breast specialists was posted from April 23rd to June 11th, 2020 on membership list serves and social media platforms of the National Accreditation Program for Breast Centers and the American Society of Breast Surgeons. Physician well-being was measured using 6 COVID-19 burnout emotions and the 4-item PROMIS short form for anxiety and sleep disturbance. We examined associations between treatment delays and physician well-being, adjusting for demographic factors, COVID-19 testing and ten COVID-19 pandemic concerns. RESULTS: 870 physicians completed the survey, 61% were surgeons. The mean age of physicians was 52 and 548 (63.9%) were female. 669 (79.4%) reported some delay in patient care as a result of the COVID-19 pandemic. 384 (44.1%) and 529 (60.8%) of physicians scored outside normal limits for anxiety and sleep disturbance, respectively. After adjusting for demographic factors and COVID-19 testing, mean anxiety and COVID-19 burnout scores were significantly higher among physicians whose patients experienced either delays in surgery, adjuvant chemotherapy, radiation, breast imaging or specialty consultation. A multivariable model adjusting for ten physician COVID-19 concerns and delays showed that "delays will impact my emotional well-being" was the strongest concern associated with anxiety, sleep disturbance and COVID-19 burnout factors. CONCLUSIONS: Breast cancer treatment delays during the initial surge of the COVID-19 pandemic in the United States were associated with a negative impact on physician emotional wellness.

PURPOSE: More women with unilateral early stage breast cancer are electing bilateral mastectomy (BM). Many cite anxiety, fear of recurrence, and certain aesthetic desires in their decision-making. Yet conflicting data exist regarding how these factors both inform and are modulated by medical decision-making, especially among women eligible for breast conservation (BCT). This study sought to assess the trajectories of women undergoing various surgical procedures for breast cancer. METHODS: We performed a prospective longitudinal study of women with unilateral, non-hereditary breast cancer who underwent BCT, unilateral mastectomy (UM), or BM. Women completed surveys before surgery and at 1, 9, and 15 months postop. Surveys included questions about treatment preferences, decisional control, the HADS-A anxiety scale, the Fear of Relapse/Recurrence Scale (FRRS), and the BREAST-Q. The Kruskal-Wallis test was used to compare outcomes between BCT, UM, and BM groups at each time point. RESULTS: 203 women were recruited and 177 (87.2%) completed 15-month follow-up. Of these, 101 (57.0%) underwent BCT, 33 (18.6%) underwent UM, and 43 (24.2%) underwent BM. Generalized anxiety and FRRS scores were similar between BCT, UM, and BM groups and declined uniformly after surgery. Although baseline breast satisfaction was similar between groups, at 15 months, it was significantly lower in BM patients than in BCT patients. Women who felt "very" confident and "very" informed before surgery had lower anxiety, lower fear of recurrence, better psychosocial well-being (PSWB), and greater breast satisfaction at 15 months. CONCLUSION: While patients who undergo mastectomy have less long-term breast satisfaction, all patients can expect to experience similar improvements in anxiety and PSWB. Efforts should be made to ensure that patients are informed and confident regardless of which surgery is chosen, for this is the greatest predictor of better outcomes.

BACKGROUND: Few decision aids for newly diagnosed breast cancer patients are used by surgeons during their consultations with patients. METHODS: From 2017 to 2019, an online interactive breast cancer in-visit decision aid (BIDA) was used on 63 patients and 57 patients underwent usual care (UC). We compared knowledge, decision involvement, anxiety and distress (HADS scale), quality of life (PROMIS), fear of recurrence, body image, and patient values between BIDA and UC before surgery. A knowledge score of ≥ 57% was considered "high knowledge." RESULTS: A total of 188 patients were enrolled of which 120 (63.8%) completed all study procedures. Patient demographic characteristics and anxiety and quality of life (QOL) at baseline were similar between patients in BIDA and UC cohorts. After seeing the surgeon, patients in the BIDA group had higher composite knowledge scores compared with UC patients [n = 55 (87.3%) vs. n = 39 (68.4%) respectively, p = 0.012]. Patients in the BIDA cohort reported being asked more often their surgical preference (p = 0.013) and discussing bilateral mastectomy (BM) as an option (p = 0.048). There was a trend of less patients in the BIDA cohort undergoing BM then in the UC cohort [10 (15.9%) vs. 14 (24.6%), p = 0.49]. Anxiety and distress, QOL, fear of recurrence, and body image were not significantly different between BIDA and UC cohorts. CONCLUSIONS: A decision aid used by surgeons during their consultation was associated with higher knowledge levels, patients reporting more discussion about BM, and a trend of lower BMs. A larger study with more patients is needed to confirm this finding.

BACKGROUND: The utilization of OncotypeDx in the setting of neoadjuvant chemotherapy (NCT) is not well defined. The objective of this study was to determine what proportion of hormone receptor (HR)-positive patients undergoing NCT would not benefit from chemotherapy based on OncotypeDx recurrence scores (RS) and predictors of a high RS as defined by the TAILORx trial. METHODS: The National Cancer Data Base was used to identify patients with unilateral clinical stage I-III HR+/Her2- breast cancer who had an OncotypeDx score and who had undergone NCT. Patients undergoing adjuvant chemotherapy were used as a comparison group. RESULTS: Of 307,666 patients, 41.8% had testing with OncotypeDx. Of these, 76.6% had no chemotherapy, 22.3% adjuvant chemotherapy, and 1.1% NCT. OncotypeDx testing in NCT patients increased from 4.9% in 2010 to 8.2% in 2015. Of NCT patients with OncotypeDx testing, 11.6% had RS < 11, 44.4% RS 11-25, and 43.9% RS > 25. In patients age ≤ 50 years, 14.5% had RS < 11, 12.4% RS 11-15, 31.4% RS 16-25, and 41.7% RS > 25. Predictors of RS > 25 on multivariable analysis included grade 3 tumors (odds ratio [OR] 3.83) and PR-negative tumors (OR 5.26) but not clinical T or N stage (p > 0.05). CONCLUSIONS: More than half of patients with OncotypeDx testing are being overtreated with NCT, and a third of younger patients are being overtreated. Predictors of a high RS are reliably available at core biopsy, suggesting an application of OncotypeDx in determining the need for NCT for some HR-positive breast cancers.

BACKGROUND: Nipple-sparing mastectomies (NSMs) with reconstruction are believed to be more difficult to perform than skin-sparing mastectomies (SSMs), but there is little quantitative data to support this claim. METHODS: This prospective study analyzed four surgeons performing mastectomies. Electromyography (EMG) electrodes placed on selected muscle groups on each surgeon were used to capture muscle exertion intraoperatively and a percentage of maximum voluntary exertion was calculated (%MVE). Data regarding surgeon demographics, exercise habits, musculoskeletal problems, and surgery-specific workload was collected using a questionnaire. RESULTS: A total of 61 mastectomies were analyzed; 40 were NSM and 21 were SSM/total mastectomies. NSM were considered to be more mentally demanding and physically demanding than SSM (p < 0.001). When the surgeons' EMG data was analyzed as a group, there was a statistically significant difference in %MVE for NSM versus SSM at high muscle activity in bilateral anterior deltoid muscle groups and at average muscle activity for the left anterior deltoid muscle only. At low muscle activity, there was a statistically significant increase in activation for SSM versus NSM in bilateral cervical erector spinae. Repeated measures ANOVA was performed, which showed statistically significant differences at high muscle activity between NSM and SSM in the left cervical erector spinae and bilateral anterior deltoid muscles. CONCLUSIONS: Our pilot study shows that intraoperative EMGs can assess muscle activity for mastectomy operations and show a difference between NSM and SSM. This is the first study to provide quantitative data on muscle strain with NSM.

BACKGROUND: In 2014, the Society of Surgical Oncology and American Society for Radiation Oncology guidelines defined negative margin for stage I and II breast cancer as "no tumor on ink." We hypothesized that repeat operation rates have decreased since the guideline introduction and would be associated with changes in overall surgical trends. STUDY DESIGN: The National Cancer Database was used to identify women who underwent initial breast-conserving surgery (BCS) for stage I and II breast cancer from 2004 to 2015. RESULTS: Of 521,578 patients that underwent initial BCS, 82.7% had BCS alone and 17.3% had repeat operation: 67% with BCS followed by another BCS, 24% with BCS followed by unilateral mastectomy, and 9% with BCS followed by bilateral mastectomy (BM). The repeat operation rate decreased from 16.2% in 2004 to 14.0% in 2015 (p < 0.01). Breast-conserving surgery with repeat BCS decreased from 12.8% to 9.7%, and BCS followed by BM increased from 0.7% in 2004 to 1.9% 2013, then decreased to 1.4% in 2015. Trends for all surgical patients regardless of initial procedure showed a BCS rate of 64.0% in 2013 that increased to 67.6% in 2015. The BM rate increased from 4.6% in 2004 to 13.6% in 2013, then decreased to 12.8% in 2015 (p < 0.05). Adjusted multivariable regression found independent predictors of repeat operation to be diagnosis before 2014 (odds ratio [OR] 1.25), age younger than 50 years (OR 1.70), Her2neu receptor-positive tumors (OR 1.61), and lobular histology (OR 1.61). CONCLUSIONS: Repeat operation rates are decreasing after 2014, which is also associated with a rise in BCS and decrease in BM rates. Dissemination of margin guidelines for early-stage breast cancer might be impacting overall surgical trends.
