A study conducted at the First Affiliated Hospital of Nanjing Medical University in China evaluated the diagnostic yield of ultrasonography (US)-guided core needle biopsy (CNB) for soft tissue tumors (STTs) and analyzed the factors contributing to diagnostic failure. The study included 139 patients with STTs who underwent both US-guided CNB and surgical resection. The diagnostic yield of US-guided CNB for STTs was found to be 78.4%, but when considering only the correct biological potential classification of STTs, the yield increased to 80.6%. Adipocytic tumors, vascular tumors, and indeterminate US diagnosis were identified as risk factors for diagnostic failure, while grade III vascular density in Color Doppler US improved diagnostic accuracy. The study concluded that US-guided CNB can be an effective modality for diagnosing STTs, with increased yield in certain cases. [Extracted from the article] |
