Core Needle Biopsy Versus Fine-Needle Aspiration for Lymph Node Evaluation in Breast Cancer: Diagnostic Accuracy and Cost Analysis in a Public Health System

Key Points

To evaluate the diagnostic accuracy and cost-effectiveness of core needle biopsy (CNB) versus fine-needle aspiration (FNA) for lymph node assessment in breast cancer.
Comparison of CNB and FNA diagnostic accuracy
Cost analysis of both techniques
Evaluation within a public health system
Focus on low- and middle-income countries
CNB shows higher diagnostic accuracy than FNA
CNB is more cost-effective than FNA
Prioritizing CNB can improve resource allocation in public healthcare systems

Abstract

CNB offers superior diagnostic performance and greater economic efficiency compared with FNA for lymph node evaluation in breast cancer. Prioritizing CNB as the first-line diagnostic approach could improve resource allocation in public healthcare systems, particularly in low- and middle-income countries where cost-effectiveness is crucial to expanding access to high-quality cancer care.
