Article Synopsis
- A multicenter study aimed to develop a risk stratification system (RSS) using ultrasonography (US) and clinical details to predict the malignancy of soft tissue masses (STMs).
- The study analyzed data from over 1,000 patients, categorizing STMs into six risk categories based on clinical and US characteristics, such as age and mass size.
- The RSS showed strong diagnostic accuracy with AUC values of 0.883 and 0.849 in different test sets, indicating it could enhance communication among healthcare providers and improve treatment decisions for STM patients.
Objective: To evaluate the effectiveness of contrast-enhanced ultrasound (CEUS) guided core needle biopsy (CNB) in diagnosing soft tissue tumors (STTs) and to identify the conventional ultrasonography (US) features of STTs that are recommended for CEUS-guided CNB.
Materials And Methods: A retrospective study was conducted on 123 patients with surgically confirmed STTs. Before surgeries, all subjects underwent CNB under the guidance of US or CEUS.
Analysis on diagnostic failure of US-guided core needle biopsy for soft tissue tumors.

Purpose: To evaluate the diagnostic yield of ultrasonography (US)-guided core needle biopsy (CNB) in the diagnosis of soft tissue tumors (STTs) and to analyze the failure factors.
Methods: 139 patients with STTs that underwent both US-guided CNB and surgical resection were collected retrospectively. Compared with the histopathological results of surgical resection, the biopsy failure was defined as the following conditions: indefinitive diagnosis, including insufficient samples and unknown subtypes with correct biological potential classification; wrong diagnosis, including wrong biological potential classification and wrong subtypes with correct biological potential classification.
