Background: Breast cancer incidence rates are rising in Africa and mortality is highest in West Africa. Reasons for poor survival are multifactorial but delays in seeking appropriate health care result in late presentation which contributes significantly to poor outcomes. Total delays of more than 3 months have been associated with advanced stage at presentation and poorer survival.

Purpose: Breast cancer is the leading type of cancer diagnosed and the second leading cause of cancer-related death in Ghana. Mammography and ultrasound have proven benefits in the early detection of breast cancer. This study evaluates mammography, breast ultrasound, and radiology work force availability throughout Ghana.

Purpose: Assessing risk of recurrence for nonmetastatic triple-negative breast cancer (TNBC) is a key determinant of therapeutic strategy. The best predictor of recurrence risk is failure to achieve a pathologic complete response after preoperative chemotherapy, but it imperfectly correlates with the definitive end points of relapse-free and overall survival (OS). The inability to accurately predict recurrence has led to increasingly toxic treatment regimens for patients with early-stage TNBC.

Purpose: Breast cancer is the most frequent cancer and second most common cause of cancer-related death in Ghana. Early detection and access to diagnostic services are vital for early treatment initiation and improved survival. This study characterizes the geographic access to hospital-based breast cancer diagnostic services in Ghana as a framework for expansion.

Introduction: Breast cancer is the most diagnosed cancer among Mongolian women and mortality rates are high. We describe a virtual multi-institutional and multidisciplinary tumor board (MTB) for breast cancer created to assist the National Cancer Center of Mongolia.

Materials And Methods: A virtual MTB for breast cancer was conducted with participation of two United States and 1 Mongolian cancer centers.

Breast cancer in Ghana is a growing public health problem with increasing incidence and poor outcomes. Lack of access to comprehensive treatment in Ghana may be a contributing factor to its high mortality. The purpose of this study was to evaluate the availability of treatments nationwide and systematically identify high yield areas for targeted expansion.

PET/CT with F-fluoroestradiol (FES) (FDA-approved in 2020) depicts tissues expressing estrogen receptor (ER). Invasive lobular carcinoma (ILC) is commonly ER positive. The primary aim of this study was to assess the frequency with which sites of histologically proven ILC have abnormal uptake on FES PET/CT.

Article Synopsis
  • Palpable ductal carcinoma in-situ (pDCIS) is a type of DCIS that presents as a clinical mass and is hypothesized to be more aggressive than screen-detected DCIS.
  • A study analyzed 83 female patients with DCIS, finding that pDCIS lesions were larger and more often biopsied using ultrasound, but both types had similar rates of recurrence and upgrades to invasive cancer.
  • The findings suggest that while pDCIS shows some aggressive characteristics, it does not significantly differ from screen-detected DCIS in terms of recurrence or progression to invasive disease.

Purpose: Breast cancer-related lymphedema (BCRL) represents a significant concern for patients following breast cancer treatment, and assessment for BCRL represents a key component of survivorship efforts. Growing data has demonstrated the benefits of early detection and treatment of BCRL. Traditional diagnostic modalities are less able to detect reversible subclinical BCRL while newer techniques such as bioimpedance spectroscopy (BIS) have shown the ability to detect subclinical BCRL, allowing for early intervention and low rates of chronic BCRL with level I evidence.

Purpose: Breast cancer-related lymphedema (BCRL) represents a dreaded complication of breast cancer treatment that can lead to morbidity, diminished quality of life, and psychosocial harm and is associated with increased costs of care. Increasingly, data has supported the concept of prospective BCRL surveillance coupled with early intervention to mitigate these effects.

Methods: We performed a systematic review of the literature searching for published randomized and prospective data evaluating prospective BCRL surveillance with early intervention.

Granulomatous lobular mastitis (GLM) is a rare and chronic benign inflammatory disease of the breast. Difficulties exist in the management of GLM for many front-line surgeons and medical specialists who care for patients with inflammatory disorders of the breast. This consensus is summarized to establish evidence-based recommendations for the management of GLM.

Objectives: Define the services available for the care of breast cancer at hospitals in the Eastern Region of Ghana, identify areas of the region with limited access to care through geospatial mapping, and test a novel survey instrument in anticipation of a nationwide scale up of the study.

Design: A cross-sectional, facility-based survey study.

Setting: This study was conducted at 33 of the 34 hospitals in the Eastern Region of Ghana from March 2020 to May 2020.

Background: Transitioning from trainee to attending surgeon requires learners to become educators. The purpose of this study is to evaluate educational strategies utilized by surgeons, define gaps in preparation for operative teaching, and identify opportunities to support this transition.

Methods: A web-based, Association of Surgical Education approved survey was distributed to attending surgeons.

Background: The Gambia has one of the lowest survival rates for breast cancer in Africa. Contributing factors are late presentation, delays within the healthcare system, and decreased availability of resources. We aimed to characterize the capacity and geographic location of healthcare facilities in the country and calculate the proportion of the population with access to breast cancer care.

Background: There exists a dogma of surgical nihilism for patients with cirrhosis and breast cancer causing de-escalation of surgery and impacting survival. We hypothesized that breast cancer surgery would not result in a significant change in the Model for End-Stage Liver Disease-Sodium (MELD-Na) scores before and after surgery.

Methods: We performed a single institutional retrospective review of medical records between January 2013 and July 2019 of patients with concurrent cirrhosis and breast cancer.

Background: An arteriovenous fistula (AVF) exposes the outflow vein to arterial magnitudes and frequencies of blood pressure and flow, triggering molecular pathways that result in venous remodeling and AVF maturation. It is unknown, however, how venous remodeling, that is lumen dilation and wall thickening, affects venous mechanical properties. We hypothesized that a fistula is more compliant compared with a vein because of altered contributions of collagen and elastin to the mechanical properties.

Objective: Statin therapy has been associated with a decreased incidence of venous thromboembolism (VTE) in clinical trials and enhanced thrombus resolution in animal models. The effect of statins on thrombus resolution has not been reported clinically. This study investigates the association of statins with thrombus resolution or improvement in patients with deep venous thrombosis (DVT).

Gallbladder agenesis (GA) is an extremely rare congenital entity. The incidence is around 1 per 6500 live births. The majority of patients, estimated between 50 to 70 percent, remain asymptomatic while those who are symptomatic report symptoms mimicking biliary colic.

Article Synopsis
  • The Caprini model evaluates venous thromboembolism risk using 30 factors and aims to determine its correlation with pulmonary embolism (PE) prevalence in deep venous thrombosis (DVT) patients.
  • A study analyzed 838 DVT patients, revealing that 25.9% had PE, with a significant portion presenting as hemodynamically significant.
  • Results showed no strong link between the Caprini model and PE risk, indicating that prior surgery and sepsis are linked to lower PE prevalence, while proximal DVT is linked to higher rates of significant PE.

Objective: Provoked deep venous thrombosis (DVT) is precipitated by a specific event. This paper compares the characteristics of provoked DVT in patients with transient risk (TR) factors and patients with continuous risk (CR) factors.

Methods: A retrospective review of records of all consecutive patients diagnosed with DVT between January 2013 and August 2014 was performed.
