Proportion of Patients With Ductal Carcinoma In Situ That Qualify for Observation Criteria Set Forth by Clinical Trials.

BACKGROUND: The COMET, LORD, and LORIS clinical trials are investigating the role of active surveillance in low-risk ductal carcinoma in situ (DCIS). The objective of this study was to identify the proportion of patients eligible for these trials amongst a cohort of patients treated at our institution. METHODS: Retrospective chart review was performed of patients diagnosed with DCIS who were treated from 2013 to 2022. Clinical, tumor, and imaging inclusion and exclusion criteria of the aforementioned observation trials were applied to determine the proportion of patients eligible for each trial. Upgrade rate to invasive cancer were examined across all three groups. RESULTS: Of 1223 patients diagnosed with DCIS, applying the criteria of each trial, 245 (20%), 238 (19.4%), and 264 (21.6%) patients were eligible for the COMET, LORD, and LORIS trials, respectively. High-grade DCIS and mass on imaging had the largest impact on exclusion. Nineteen (7.8%) of women who qualified for COMET were upgraded to invasive disease at excision, compared to 18 (7.6%) for LORD, and 19 (7.2%) for LORIS. CONCLUSIONS: One in five patients diagnosed with DCIS at our institution would qualify for observation with current trial eligibility. Observation of DCIS may have limited impact on all DCIS patients.

Patient values in breast cancer surgical decision-making - The WhySurg study.

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.

Rates of newly diagnosed breast cancer at commission on cancer facilities during the early phase of the COVID-19 pandemic.

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.

Trends in bilateral mastectomy rates among different racial backgrounds: A National Cancer Database study.

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.

Rates of Bilateral Mastectomy in Patients With Early-Stage Breast Cancer.

This cohort study builds on previous research from the National Cancer Database to assess whether rates of bilateral mastectomy continue to increase.

Male Breast Cancer Patient and Surgeon Experience: The Male WhySurg Study.

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.
