Differential preferences in breast aesthetics by self-identified demographics assessed on a national survey

Boyd, Carter J; Bekisz, Jonathan M; Hemal, Kshipra; Sorenson, Thomas J; Karp, Nolan S
There is a paucity of literature examining how preferences differ amongst various demographic groups. This study aimed to assess how perceptions of the ideal breast differ between respondents stratified by self-identified demographic factors. A cohort of 25 patients from the senior surgeon's practice presenting for breast surgery was assembled. Pre-operative anteroposterior photographs of these patients were distributed via Qualtrics (Seattle, WA) to a large sample designed to be representative of the demographics of the United States. Survey questions aimed to measure respondents' impressions of 'breast attractiveness'. Respondents were asked to rate breasts on a Likert scale. Survey responses were analysed for differences in breast aesthetic preferences by sex, gender, sexual orientation, and race. Males rated all breasts higher on the Likert scale for attractiveness than females (2.8 vs 2.5, p < 0.001). Despite this discrepancy, ratings amongst male and female respondents were highly correlated with one another (R = 0.940; p < 0.0001). Considering sexual orientation, individuals attracted to women provided significantly higher attractiveness ratings to all breasts compared to individuals attracted to men only (2.8 vs 2.5, p < 0.001). White or Caucasian individuals ascribed significantly higher breast attractiveness ratings than Asian individuals (2.7 vs 2.2, p < 0.001), but not Black or African American individuals (2.7 vs 2.4, p = 0.23). Despite these racial discrepancies in mean breast attractiveness, ratings amongst the three groups were highly correlated. In a sample representative of the United States, a difference in breast aesthetic appraisal was observed by demographic factors. These findings merit further investigation to understand these trends and observations.

Artificial Intelligence as a Triage Tool during the Perioperative Period: Pilot Study of Accuracy and Accessibility for Clinical Application

Boyd, Carter J; Hemal, Kshipra; Sorenson, Thomas J; Patel, Parth A; Bekisz, Jonathan M; Choi, Mihye; Karp, Nolan S
BACKGROUND/UNASSIGNED:Given the dialogistic properties of ChatGPT, we hypothesized that this artificial intelligence (AI) function can be used as a self-service tool where clinical questions can be directly answered by AI. Our objective was to assess the content, accuracy, and accessibility of AI-generated content regarding common perioperative questions for reduction mammaplasty. METHODS/UNASSIGNED:less than 0.05. RESULTS/UNASSIGNED:< 0.0001). AI outputs specifically recommended following surgeon provided postoperative instructions in 82.5% of instances. CONCLUSIONS/UNASSIGNED:Currently available AI tools, in their nascent form, can provide recommendations for common perioperative questions and concerns for reduction mammaplasty. With further calibration, AI interfaces may serve as a tool for fielding patient queries in the future; however, patients must always retain the ability to bypass technology and be able to contact their surgeon.

Hardy-Abeloos, Camille; Xiao, Julie; Oh, Cheongeun; Barbee, David; Shah, Bhartesh; Maisonet, Olivier; Perez, Carmen; Adams, Sylvia; Schnabel, Freya; Axelrod, Deborah; Guth, Amber; Karp, Nolan; Cahlon, Oren; Gerber, Naamit
Purpose: Our institution was an early adopter of 5-fraction accelerated partial breast irradiation (ABPI) to treat women with early-stage breast cancer. This study reports long-term oncologic and cosmetic outcomes. Methods: We included patients receiving APBI 600 cGy × 5 fx delivered every other day or every day between 2010 and 2022. Logistic regression models were used to identify factors associated with development of late toxicities, clinician, and patient-rated cosmesis. Kaplan"“Meier methodology was used to calculate overall survival (OS), disease-free survival (DFS), and locoregional recurrence-free survival (LR-RFS). Results: 442 patients received APBI either daily (56%) or every other day (44%) in the prone position (92%). At a median follow-up of 48 months (range: 5.96"“155 months), 12 (2.7%) patients developed a local recurrence (LR). Out of 258 patients with > 3-month toxicity data available, the most common late grade ≥ 2 adverse event was breast fibrosis (6.2%). On multivariate analysis, daily APBI treatment (vs every other day) did not correlate with an increased risk of any late grade ≥ 2 toxicity though it did correlate with a lower risk of any late grade ≥ 2 fibrosis. Overall, at a median follow-up of 80 months, the rates of good"“excellent physician and patient-rated cosmesis were 95% and 85%, respectively, with no difference between patients treated on consecutive vs. every other day. On multivariate analysis, patients who did not receive any adjuvant therapy were at increased risk of developing a LR. Five-year OS, LRFS, and DFS were 97.2%, 97.7%, and 89.5%, respectively. Conclusions: Five-fraction APBI delivered primarily in the prone position either daily or every other day was effective with low rates of local recurrence, minimal toxicity, and excellent cosmesis at long-term follow-up.

Low Cancer Occurrence Rate following Prophylactic Nipple-Sparing Mastectomy

Boyd, Carter J; Ramesh, Sruthi; Bekisz, Jonathan M; Guth, Amber A; Axelrod, Deborah M; Shapiro, Richard L; Hiotis, Karen; Schnabel, Freya R; Karp, Nolan S; Choi, Mihye
BACKGROUND:Nipple-sparing mastectomy (NSM) has become widely available for breast cancer prophylaxis. There are limited data on its long-term oncologic safety. The objective of this study was to determine the incidence of breast cancer in patients who underwent prophylactic NSM. METHODS:All patients undergoing prophylactic NSM at a single institution from 2006 through 2019 were retrospectively reviewed. Patient demographic factors, genetic predispositions, mastectomy specimen pathology, and oncologic occurrences at follow-up were recorded. Descriptive statistics were performed where necessary to classify demographic factors and oncologic characteristics. RESULTS:A total of 871 prophylactic NSMs were performed on 641 patients, with median follow-up of 82.0 months (standard error 1.24). A total of 94.4% of patients ( n = 605) underwent bilateral NSMs, although only the prophylactic mastectomy was considered. The majority of mastectomy specimens (69.6%) had no identifiable pathology. A total of 38 specimens (4.4%) had cancer identified in mastectomy specimens, with ductal carcinoma in situ being the most common (92.1%; n = 35). Multifocal or multicentric disease was observed in seven cases (18.4%) and lymphovascular invasion was identified in two (5.3%). One patient (0.16%), who was a BRCA2 variant carrier, was found to have breast cancer 6.5 years after prophylactic mastectomy. CONCLUSIONS:Overall primary oncologic occurrence rates are very low in high-risk patients undergoing prophylactic NSM. In addition to reducing the risk of oncologic occurrence, prophylactic surgery itself may be therapeutic in a small proportion of patients. Continued surveillance for these patients remains important to assess at longer follow-up intervals. CLINICAL QUESTION/LEVEL OF EVIDENCE/METHODS:Risk, IV.

The Underused Superomedial Pedicle Reduction Mammaplasty: Safe and Effective Outcomes

Morrison, Kerry A; Karp, Nolan S; Choi, Mihye
BACKGROUND:The superomedial pedicle for reduction mammaplasty remains less commonly performed than the inferior pedicle. This study seeks to delineate the complication profiles and outcomes for reduction mammaplasty using a superomedial pedicle technique in a large series. METHODS:A retrospective review was conducted of all consecutively performed reduction mammaplasty cases at a single institution by two plastic surgeons over a 2-year period. All consecutive superomedial pedicle reduction mammaplasty cases for benign symptomatic macromastia were included. RESULTS:A total of 462 breasts were analyzed. Mean age was 38.3 ± 13.38 years, mean body mass index was 28.5 ± 4.95, and mean reduction weight was 644.4 ± 299.16 g. Regarding surgical technique, a superomedial pedicle was used in all cases; Wise-pattern incision was used in 81.4%, and short-scar incision was used in 18.6%. The mean sternal notch-to-nipple measurement was 31.2 ± 4.54 cm. There was a 19.7% rate of any complication, the majority of which were minor in nature, including any wound healing complications treated with local wound care (7.5%) and scarring with intervention in the office (8.6%). There was no statistically significant difference in breast reduction complications and outcomes using the superomedial pedicle, regardless of sternal notch-to-nipple distance. Body mass index ( P = 0.029) and breast reduction specimen operative weight ( P = 0.004) were the only significant risk factors for a surgical complication, and with each additional gram of reduction weight, the odds of a surgical complication increased by 1.001. Mean follow-up time was 40.5 ± 7.1 months. CONCLUSION:The superomedial pedicle is an excellent option for reduction mammaplasty, portending a favorable complication profile and long-term outcomes.

Preauthorization Inconsistencies Prevail in Reduction Mammaplasty

Boyd, Carter J.; Hemal, Kshipra; Cohen, Joshua M.; Daar, David A.; Gwin, John; Zupko, Karen; Karp, Nolan S.
Background: Despite evidence documenting the physical and psychological benefits of breast reduction, third-party payer approval remains a cumbersome process. The objective of this study was to assess differences in medical necessity criteria for reduction mammaplasty among US insurance carriers while analyzing trends in claim denials and appeals. Methods: The medical necessity criteria for reduction mammaplasty were retrieved from seven large health insurance carriers. Data were extracted from each policy, including claim requirements for approval. Additionally, prospective data on claims and denials submitted from January through August 2022 were collected from The Auctus Group, a medical consulting firm. Results: All the policies have been updated since January 2020. Five of the seven policies specifically listed what documentation was required for preauthorization approval, with five third-party payers requiring photograph documentation. Policies required documentation of one to three symptoms lasting from 6 weeks to 1 year. All companies reported a tissue resection estimate threshold, but cutoffs varied. Of 380 reduction mammaplasties performed, 158 (41.6%) received a denial on initial insurance submission. Considering appeals, a total of 216 denials were reviewed with an average of 1.37 denials per patient. Of the 158 initial denials, 104 (65.8%) of these were from claims that received preauthorization. In 12 cases, third-party payers stated that no prior authorization was necessary yet still denied the claim. Conclusions: Wide variability exists in medical necessity criteria for reduction mammaplasty policies among major insurance carriers. These nuances introduce inefficiencies for practices contributing to high denial and appeal rates while delaying surgical care for patients.

No Cancer Occurrences in 10-year Follow-up after Prophylactic Nipple-sparing Mastectomy

Boyd, Carter J.; Bekisz, Jonathan M.; Ramesh, Sruthi; Hemal, Kshipra; Guth, Amber A.; Axelrod, Deborah M.; Shapiro, Richard L.; Hiotis, Karen; Schnabel, Freya R.; Choi, Mihye; Karp, Nolan S.
Background: Prophylactic nipple-sparing mastectomies (NSM) have become increasingly common, although there is little long-Term data on its efficacy in prevention of breast cancer. The objective of this study was to assess the incidence of breast cancer in a cohort of patients undergoing prophylactic NSM with a median follow-up of 10 years. Methods: Patients receiving prophylactic NSM at a single institution from 2006 to 2019 were included in a retrospective nature. Patient demographics, genetic mutations, operative details, and specimen pathology were recorded, and all postoperative patient visits and documentation were screened for cancer occurrence. Descriptive statics were performed where appropriate. Results: Two hundred eighty-four prophylactic NSMs were performed on 228 patients with a median follow-up of 120.5 ± 15.7 months. Roughly, a third of patients had a known genetic mutation, with 21% BRCA1 and 12% BRCA2. The majority (73%) of prophylactic specimens had no abnormal pathology. The most commonly observed pathologies were atypical lobular hyperplasia (10%) and ductal carcinoma in situ (7%). Cancer was identified in 10% of specimens, with only one case of lymphovascular invasion. Thus far, there have been no incidences of locoregional breast cancer occurrence in this cohort. Conclusions: The long-Term breast cancer occurrence rate in this cohort of prophylactic NSM patients at the time of this study is negligible. Despite this, continued surveillance of these patients is necessary until lifetime risk of occurrence following NSM has been established.
