Impact of the COVID-19 pandemic on breast cancer mortality in the US: estimates from collaborative simulation modeling.
This study’s objective was to project the impact of COVID-19 on future breast cancer mortality between 2020 and 2030. Three established Cancer Intervention and Surveillance Modeling Network breast cancer models were used to model reductions in mammography screening use, delays in symptomatic cancer diagnosis, and reduced use of chemotherapy for women with early-stage disease for the first 6 months of the pandemic with return to prepandemic patterns after that time. The models project by 2030 950 cumulative excess breast cancers deaths related to reduced screening, 1314 deaths associated with delayed diagnosis of symptomatic cases, and 151 deaths associated with reduced chemotherapy use in women with hormone positive, early-stage cancer.

Effect of a randomized trial of a web-based intervention on patient-provider communication about breast density.
This study evaluated a personalized web-based intervention between women and their providers designed to improve breast cancer risk communication. This randomized trial included women aged 40-69 years with 504 women in the control group and 492 women who used the intervention website. The website included information about breast density, personalized breast cancer risk, chemoprevention, and magnetic resonance imaging. Participants self-reported their communication about density with providers at 6 weeks and 12 months. Women in the intervention arm were 2.39 times more likely to report density communication at 6 weeks than the control arm. This effect persisted at 12 months. At 6 weeks the effect was only significant among women who reported versus those who did not report any previous density discussions. A quarter of women in each arm did not have a density conversation at any point during the study.

Arm morbidity after local therapy for young breast cancer patients.
This study assessed patient-reported arm morbidity in the Young Women's Breast Cancer Study (YWS). Participants were over 1300 women with breast cancer diagnosed at age 40 or younger and who were enrolled in the YWS. Findings showed that high rates of self-reported arm morbidity in young breast cancer survivors were reported, particularly in patients receiving axillary lymph node dissection and post-mastectomy radiation therapy. Recommendations included attention to the risks and benefits of differing local therapy strategies for axillary lymph node dissection and post-mastectomy radiation therapy patients.

Association of local therapy with quality-of-life outcomes in young women with breast cancer.
Researchers examined the association of surgery with longer-term satisfaction and quality of life (QOL) in young breast cancer survivors. Participants were women 40 years or older who enrolled in the Young Women's Breast Cancer Study. The results suggested that local therapy in young breast cancer survivors is persistently associated with poorer scores in multiple QOL domains, particularly among those treated with mastectomy and radiotherapy, irrespective of breast reconstruction. Socioeconomic stressors also appear to play a role.

Impact of fertility concerns on endocrine therapy decisions in young breast cancer survivors.
The diagnosis and treatment of breast cancer can have profound effects on a young woman's family planning and fertility, particularly among women with hormone receptor-positive breast cancer. In this paper the authors discuss the Young Women's Breast Cancer Study, a multicenter cohort of women aged 40 years or younger and newly diagnosed with breast cancer from 2006 to 2016. The investigators concluded that concern about fertility was a contributor to adjuvant ET decisions among a substantial proportion of young breast cancer survivors.

Trends in contralateral prophylactic mastectomy utilization for small unilateral breast cancer.
This study describes trends in contralateral prophylactic mastectomy (CPM) utilization for small unilateral breast cancer instead of breast-conserving surgery (BCS) which is recommended. The authors used the National Cancer Database to identify women with unilateral, T1 breast cancer. Of the total cohort of 765,487, 69% underwent BCS and 31% chose mastectomy. Of 176,673 women aged 70 years or older, 75% underwent BCS and 25% chose mastectomy. CPM rates have increased in both cohorts since 2006. Patient factors such as younger age, white rate, private insurance, tumor factors, and facility factors were associated with increased CPM rates compared with unilateral mastectomy.

The "sweet spot" revisited: optimal recall rates for cancer detection with 2D and 3D digital screening mammography in the Metro Chicago Breast Cancer Registry.
The authors examined the trade-offs for higher recall rates in terms of biopsy recommendations and cancer detection in mammography in a single large health care organization. 2D analog, 2D digital, and 3D digital mammography screenings among women 40-79 years old with cancer follow-up were examined. They found that the results of their investigation were in contrast to those of a recent study suggesting appropriateness of higher recall rates. They concluded that optimal cancer detection appeared to be in the recall rate range of 7-9% for both 2D digital mammography and 3D tomosynthesis.

Variations in persistent use of low-value breast cancer surgery.
Through the Choosing Wisely campaign, surgical specialties identified 4 low-value breast cancer operations. Preliminary data suggest varying rates of deimplementation and have identified patient-level and clinician-level determinants of continued overuse. However, little information exists about facility-level variation or determinants of differential deimplementation. In this retrospective cohort study the investigators sought to identify variation and determinants of persistent use of low-value breast cancer surgical care.

Assessment of a risk-based approach for triaging mammography examinations during periods of reduced capacity.
Breast cancer screening, surveillance, and diagnostic imaging services were profoundly limited during the initial phase of the coronavirus disease 2019 (COVID-19) pandemic. The objective of this population-based cohort study was to develop a risk-based strategy for triaging mammograms during periods of decreased capacity. The investigators found that clinical indication and individual risk factors were associated with cancer detection and suggest these may be useful for prioritizing mammography in times and settings of decreased capacity.

Comparative access to and use of digital breast tomosynthesis screening by women's race/ethnicity and socioeconomic status.
This study looked at access to digital breast tomography (DBT) versus regular mammography and whether women of minority race/ethnicity and lower socioeconomic status experienced lower DBT access during the early adoption period and persistently lower DBT use over time. This cross-sectional study included 92 geographically diverse imaging facilities across 5 US states, with over 2.3 million screening examinations performed among women aged 40 to 89 years from January 1, 2011, to December 31, 2017. Data were analyzed from June 2019, to August 2020. Women who used DBT increased for all women from 3.3% in 2011 to 82.6% in 2017. In 2012, Black, Hispanic, Asian American, and women with less than a high school education had lower DBT access compared to White women attending the same facility and also college graduates. Lower DBT access continued over time regardless of the number of years after facility-level DBT adoption.

Gaps in online breast cancer treatment information for older women.
This study’s goal was to assess the availability of web-based educational materials targeting older women facing early-stage breast cancer treatment. Routine use of sentinel lymph node biopsy (SLNB) and adjuvant radiotherapy offers no overall survival benefit and may not be perceived as desirable by older women. National guidelines allow omission of these treatments for older women. The authors systematically reviewed the top 25 hospital websites ranked as “Best Hospitals for Cancer” by U.S. News & World Report, as well as the websites of four prominent national cancer organizations. Only one national organization and no hospital websites included the recommendation to avoid routine SLNB. Only 2 hospitals and 2 national organizations included information for patients older than 70 years suggesting possible omission of adjuvant radiotherapy.

Medical maximizing-minimizing preferences in relation to low-value services for older women with hormone receptor-positive breast cancer: a qualitative study.
In this qualitative study, researchers conducted 30 semi-structured interviews with women age 70 or older without a previous diagnosis of breast cancer in order to elicit perspectives on breast cancer treatment in relation to their medical maximizing-minimizing preferences, as determined by the single-item maximizer-minimizer elicitation question (MM1). They found that medical maximizing-minimizing preferences in older women corresponded with preferences for breast cancer treatment options that guidelines identify as potentially unnecessary.

Trends in breast cancer treatment de-implementation in older patients with hormone receptor-positive breast cancer: a mixed methods study.
Guidelines allow for the omission of sentinel lymph node biopsy (SLNB) and post-lumpectomy radiotherapy in women >/= 70 years of age with hormone receptor-positive (HR +) breast cancer. Despite this, national data suggest these procedures have not been widely de-implemented. The objectives of this study were to evaluate trends in SLNB and post-lumpectomy radiotherapy utilization in patients who were eligible for omission and evaluate patient preferences as a target for de-implementation of low-value care.
