Introduction: Therapeutic clinical trials frequently lack diverse representation, hindering generalizability and exacerbating preexisting disparities in clinical outcomes. This study explored associations between breast cancer patient demographics, clinical trial eligibility, and enrollment in a National Cancer Institute (NCI)-designated cancer center.

Patients And Methods: This prospective cohort study included patients with breast cancer screened for therapeutic clinical trials from July 2020 to January 2024.

Mental health challenges are common following cancer diagnosis, negatively impacting treatment and quality of life for breast cancer (BC) patients. This pilot study provides an understanding of the impacts of BC diagnosis and care experiences on the mental health of patients seen at the Aga Khan University Hospital in Nairobi, Kenya. We conducted 40 in-depth interviews, including 10 women with newly diagnosed BC, 10 women with metastatic BC, 10 family members and 10 healthcare professionals.

Introduction: Cancer-related stigma is a key driver of advanced breast cancer stage in Sub-Saharan Africa (SSA). We developed and tested the impact of a breast cancer survivor-led Stigma reduction intervention (SRI) on stigma and treatment adherence of newly diagnosed patients with breast cancer in Tanzania.

Methods: Breast cancer survivors were trained on breast cancer knowledge and motivational interviewing.

Purpose: Black women are less likely to receive screening mammograms, are more likely to develop breast cancer at an earlier age, and more likely to die from breast cancer when compared to White women. Affordable Care Act (ACA) provisions decreased cost sharing for women's preventive screening, potentially mitigating screening disparities. We examined enrollment of a high-risk screening program before and after ACA implementation stratified by race.

Background: Breast cancer is the most common cancer-affecting women globally, with disproportionally high mortality rates in lower-income countries, including Ethiopia. The stage at diagnosis is a well-defined predictive system that determines the likelihood of breast cancer mortality. Early-stage breast cancer at diagnosis is associated with better treatment outcomes as compared with late stage.

Purpose: This study evaluates the relationship between geography and ethnicity on the completeness of documentation of diagnostic work-up and treatment modalities in Sudan for patients with breast cancer.

Methods: This retrospective study used data abstracted from patients with breast cancer receiving cancer care at Sudan's largest cancer centre (Radiation and Isotopes Center Khartoum) in 2017. Patient demographic and clinical characteristics were abstracted from paper medical records.

Purpose: Black women are less likely to receive screening mammograms and are at a higher lifetime risk for developing breast cancer compared to their White counterparts. Affordable Care Act (ACA) provisions decreased cost sharing for women's preventive screening, potentially mitigating screening disparities. We examined enrollment of a high-risk screening program before and after ACA implementation stratified by race.

Article Synopsis
  • - The first Lancet Oncology Commission on Global Cancer Surgery, published in 2015, emphasized the global burden of cancer and the critical role of surgical care, while highlighting existing gaps in providing safe and accessible cancer surgery.
  • - The new Commission builds on the previous work by proposing actionable solutions aimed at enhancing access to cancer surgery globally, involving expertise from international leaders in the field.
  • - It outlines solution frameworks across nine domains tailored to the six WHO regions, with eight specific actions designed to improve cancer surgical capacity and promote equity, affordability, and safety for all patients.

Breast Cancer is the most common female cancer worldwide with significant global disparities, particularly disadvantaging women of African Ancestry. Though the United States and Sub-Saharan Africa are seemingly very different settings, there are many important parallels between the experience of getting diagnosed and treated for breast cancer in these two geographic regions for women of African ancestry. This commentary explores the parallels and differences and proposes an agenda to move forward to narrow the disparities gaps for some of the worlds most vulnerable women.

Background: American Indians/Alaska Natives (AI/AN) receive less colorectal cancer (CRC) screening than other populations. Using gastroenterologist (GI) locations as a measure of colonoscopy access, we correlate GI density and AI/AN CRC screening rates.

Methods: We identified GIs from the 2016 National Provider Identifier registry, and calculated GI density per 100,000 people.

Background: Malignant phyllodes (MP) and primary breast sarcomas (PBS) are rare neoplasms with overlapping histopathologic features. We compared overall survival (OS) and estimated the association of surgery and therapies with OS.

Methods: We utilized the National Cancer Database (2004-2016).

Breast surgical oncology is a rapidly evolving field with significant advances shaped by practice-changing research. Three areas of ongoing controversy are (1) high rates of contralateral prophylactic mastectomy (CPM) in the United States despite uncertain benefit, (2) indications for and use of neoadjuvant chemotherapy (NACT) and endocrine therapy (NET), and (3) staging and treatment of the axilla, particularly after neoadjuvant systemic therapy. We discuss the patient populations for whom CPM may or may not be beneficial, indications for NACT and NET, and the trend toward de-escalation of locoregional axillary treatment.

Background: Retrospective studies have reported that breast cancer patients who perceived more personal responsibility for the surgery decision were more likely to undergo aggressive surgery. We examined this in a prospective study.

Methods: 100 newly diagnosed breast cancer patients identified their decision- making role using the Patient Preference Scale.

What Is Known And Objectives: There is a lack of consensus regarding optimal anticoagulation regimen and duration for inferior vena cava (IVC) thrombus due to the paucity of clinical evidence. A case of IVC thrombus treated with 3 months of rivaroxaban therapy is reported.

Case Description: Fifty-two-year-old male Caucasian presented following a motorcycle accident, with multiple left rib fractures requiring emergent amputation surgeries.

Purpose: Despite the increasing burden, breast cancer control in sub-Saharan Africa is insufficient. Late diagnosis and lack of early detection and screening services contribute to high mortality. Clinical breast exam (CBE) screening can be valuable in low-income countries, including use of community health workers and non-health professionals to conduct exams.

Background: The non-profit and volunteer sector has made notable contributions to delivering surgical services in low-and middle-income countries (LMICs). As an estimated 55 % of surgical care delivered in some LMICs is via charitable organizations; the financial contributions of this sector provides valuable insight into understanding financing priorities in global surgery.

Methods: Databases of registered charitable organizations in five high-income nations (United States, United Kingdom, Canada, Australia, and New Zealand) were searched to identify organizations committed exclusively to surgery in LMICs and their financial data.

Background: Breast cancer awareness and early detection are limited in sub-Saharan Africa. Resource limitations make screening mammography or clinical breast examination (CBE) by physicians or nurses impractical in many settings. We aimed to assess feasibility and performance of CBE by laywomen in urban health clinics in Malawi.

Objective: The funds available for global surgical delivery, capacity building and research are unknown and presumed to be low. Meanwhile, conditions amenable to surgery are estimated to account for nearly 30% of the global burden of disease. We describe funds given to these efforts from the USA, the world's largest donor nation.
