Are there differences in overall survival among older breast cancer patients by race and ethnicity?

Background: Non-Hispanic Black women have lower breast cancer incidence but twice the mortality of non-Hispanic White women. Recent data suggest that the overall survival difference may not be observed in older women. This study aims to determine overall survival in women aged ≥70 years with operable breast cancer by race and ethnicity and factors contributing to overall survival.

Examining the false-negative rate of a negative axillary node ultrasound-guided core needle biopsy in breast cancer patients undergoing upfront surgery.

Background: Axillary assessment in breast cancer is key to determining an upfront surgery or neoadjuvant chemotherapy (NAC) approach. We investigated the false-negative rate (FNR) of axillary-node ultrasound-guided core-needle biopsy (US-CNBx) and the surgical management of pN ​+ ​patients.

Methods: This single-institution study from 2010 to 2020 included patients with benign findings on US-CNBx and upfront surgery.

Postsurgical pyoderma gangrenosum after mastectomy with a familial component.

Postsurgical pyoderma gangrenosum (PSPG) is a rare, ulcerative skin condition that presents a diagnostic challenge due to its similar presentation to infectious etiologies in the postsurgical period-often leading to gratuitous and unnecessary surgery and antibiotic use. We report a 37-year-old female with breast cancer who received neoadjuvant chemotherapy and immunotherapy and underwent bilateral skin-sparing mastectomies who developed delayed bilateral mastectomy skin flap necrosis secondary to PSPG. This case had rare factors associated with the development of PSPG such as preoperative systemic therapy and a familial component.

Evaluating the Accuracy, Quality, and Readability of Online Breast Cancer Information.

Objective: To assess the accuracy, quality, and readability of patient-focused breast cancer websites using expert evaluation and validated tools.

Background: Ensuring access to accurate, high-quality, and readable online health information supports informed decision-making and health equity but has not been recently evaluated.

Methods: A qualitative analysis on 50 websites was conducted; the first 10 eligible websites for the following search terms were included: "breast cancer," "breast surgery," "breast reconstructive surgery," "breast chemotherapy," and "breast radiation therapy.

The Use of Sentinel Lymph Node Biopsy in Patients Undergoing Mastectomy for DCIS.

Background: Current guidelines do not recommend routine sentinel node biopsy (SLNB) for ductal carcinoma in situ (DCIS), except in the setting of mastectomy or microinvasive disease. This study aimed to evaluate national SLNB utilization in women undergoing upfront mastectomy for DCIS, identify predictors of SLNB utilization, and determine the percentage with a positive SLNB.

Methods: A retrospective cohort analysis was performed using the NCDB of women with clinical DCIS who underwent upfront mastectomy between 2012 and 2017.

The Impact of a Breast Cancer Risk Assessment on the Decision for Gender-Affirming Chest Masculinization Surgery in Transgender and Gender-Diverse Individuals: A Pilot Single-Arm Educational Intervention Trial.

Background: Persons assigned female or intersex at birth and identify as transgender and/or gender-diverse (TGD) may undergo gender-affirming chest masculinization surgery (GACMS); however, GACMS is not considered equivalent to risk-reducing mastectomies (RRM). This study aimed to estimate the prevalence of elevated breast cancer (BC) risk in TGD persons, compare self-perceived versus calculated risk, and determine how risk impacts the decision for GACMS versus RRM.

Methods: A prospective single-arm pilot educational intervention trial was conducted in individuals assigned female or intersex at birth, age ≥ 18 years, considering GACMS, without a BC history or a known pathogenic variant.

Tumors, Treatments, and Trust: Cancer Characteristics, Outcomes, and Screening Uptake in Transgender and Gender-Diverse Patients.

Background: More than 2.5 million adults in the United States identify as transgender or gender-diverse (TGD), but little data exist on cancer screening and care for this population. We examined cancer characteristics, screening adherence, genetic testing, and provider inclusive language for TGD patients with cancer.

An Annual Symposium on Disparities in Milwaukee, WI, with a 2023 Focus on Older Adults with Cancer.

Purpose Of Review: Cancer-related inequities are prevalent in Wisconsin, with lower survival rates for breast, colorectal, and lung cancer patients from marginalized communities. This manuscript describes the ongoing efforts at the Medical College of Wisconsin and potential pathways of community engagement to promote education and awareness in reducing inequities in cancer care.

Recent Findings: While some cancer inequities are related to aggressive disease biology, health-related social risks may be addressed through community-academic partnerships via an open dialogue between the community members and academic faculty.

Divergent Cellular Expression Patterns of PD-L1 and PD-L2 Proteins in Breast Cancer.

PD-L1 immunohistochemistry (IHC) has become an established method for predicting cancer response to targeted anti-PD1 immunotherapies, including breast cancer (BC). The alternative PD-1 ligand, PD-L2, remains understudied but may be a complementary predictive marker. Prospective analysis of 32 breast cancers revealed divergent expression patterns of PD-L1 and PD-L2.

Risk Factors for Skin Flap and Nipple-Areolar Necrosis in Patients Undergoing Nipple-Sparing Mastectomy With Deep Inferior Epigastric Perforator Flap Reconstruction.

Introduction: Nipple-sparing mastectomy (NSM) with deep inferior epigastric perforator (DIEP) flap reconstruction is a surgical option for select patients with or at risk of breast cancer. However, post-operative skin flap and nipple-areolar complex (NAC) necrosis remain common complications. This study aimed to identify factors associated with necrosis in patients undergoing NSM with DIEP reconstruction.

Does Neoadjuvant Chemotherapy in Clinical T1-T2 N0 Triple-Negative Breast Cancer Increase the Extent of Axillary Surgery?

Background: Current management strategies for early-stage triple-negative breast cancer (TNBC) include upfront surgery to determine pathologic stage to guide chemotherapy recommendations, or neoadjuvant chemotherapy (NAC) to de-escalate surgery, elucidate tumor response, and determine the role of adjuvant chemotherapy. However, patients who receive NAC with residual pathological nodal (pN) involvement require axillary lymph node dissection (ALND) as they are Z11/AMAROS ineligible. We aimed to evaluate the impact of NAC compared with upfront surgery on pN status and ALND rates in cT1-2N0 TNBC.

Systematic Review on Gender-Affirming Testosterone Therapy and the Risk of Breast Cancer: A Challenge for Physicians Treating Patients from Transgender and Gender-Diverse Populations.

Conflicting evidence exists about the risk of breast cancer in transgender and gender-diverse (TGD) patients treated with testosterone. This review aimed to summarize current knowledge regarding the risk of breast cancer associated with gender-affirming testosterone treatment (GATT). A systematic literature search using the Preferred Reporting Items for Systematic Review and Meta-Analysis checklist was conducted in January 2023 through Ovid, Scopus, and Web of Science databases.

National trends in neoadjuvant chemotherapy utilization in patients with early-stage node-negative triple-negative breast cancer: the impact of the CREATE-X trial.

Purpose: Neoadjuvant chemotherapy (NAC) for triple-negative breast cancer (TNBC) allows for assessment of tumor pathological response and has survival implications. In 2017, the CREATE-X trial demonstrated survival benefit with adjuvant capecitabine in patients TNBC and residual disease after NAC. We aimed to assess national rates of NAC for cT1-2N0M0 TNBC before and after CREATE-X and examine factors associated with receiving NAC vs adjuvant chemotherapy (AC).
