Analysis of Risk Factors, Treatment Patterns, and Survival Outcomes After Emergency Presentation With Colorectal Cancer: A Prospective Multicenter Cohort Study in Nigeria.
J Surg Oncol
November 2024
Background And Objectives: Prospective data on presentation and outcomes of colorectal cancer (CRC) in Nigeria are limited; however, emergency presentation with advanced disease is thought common.
Methods: Consecutive CRC patients presenting at six sites over 6 years were included. Risk factors for emergency presentation were evaluated using logistic regression methods.
Article Synopsis
- Cholecystectomy and common bile duct exploration are frequent surgeries in Nigeria that can lead to complications like biliary tree injury and retained stones, necessitating repeat surgeries.
- A study at Obafemi Awolowo University Teaching Hospital examined the use of endoscopic retrograde cholangiopancreatography (ERCP) for managing these complications from March 2018 to April 2023, using various imaging techniques before the procedures.
- The study involved 72 ERCPs on 45 patients, with common issues like ascending cholangitis and retained stones, showcasing that ERCP was successful and reduced unnecessary surgeries, with recommendations for swift referrals in such cases.
Breast Cancer Stage at Diagnosis in a Nigerian Hospital: Trend over a Decade.
West Afr J Med
December 2023
Background: Breast cancer outcomes are poor in Nigeria, partly due to late-stage diagnosis. To assess the impact of past and present interventions, a review of an institutional data base was performed to determine the trend with respect to stage at diagnosis over a decade.
Methods: A retrospective analysis of an institutional data base was performed over a decade.
Purpose: Mammography, breast ultrasound (US), and US-guided breast biopsy are essential services for breast cancer early detection and diagnosis. This study undertook a comprehensive evaluation to determine population-level access to these services for breast cancer early detection and diagnosis in Nigeria using a previously validated geographic information system (GIS) model.
Methods: A comprehensive list of public and private facilities offering mammography, breast US, and US-guided breast biopsy was compiled using publicly available facility data and a survey administered nationally to Nigerian radiologists.
The African Research Group for Oncology (ARGO) was formed in 2013 to undertake methodologically rigorous cancer research in Nigeria, and to strengthen cancer research capacity in the country through training and mentorship of physicians, scientists, and other healthcare workers. Here, we describe how ARGO's work in colorectal cancer (CRC) has evolved over the past decade. This includes the consortium's scientific contributions to the understanding of CRC in Nigeria and globally and its research capacity-building program.
