U.S., July 16 -- ClinicalTrials.gov registry received information related to the study (NCT07066774) titled 'Biopsy Needle Size in Soft Tissue Sarcoma' on July 04.
Brief Summary: Soft tissue sarcomas (STS) require accurate biopsy for diagnosis, grading, and management decisions. Although tru-cut biopsy is widely used, the optimal needle gauge remains uncertain. This study aimed to compare diagnostic accuracy and biopsy concordance rates of 14 G, 16 G, and 18 G tru-cut biopsy needles for extremity STS.
1. Is there any difference between the diagnostic accuracy measurements of 14G, 16G and 18G tru-cut biopsy needles for diagnosis of soft tissue sarcomas in extremities?
2. Do tumor size, tumor depth, tumor subtype and histological grade of ...
