Biopsy Needle Size in Soft Tissue Sarcoma
Diagnostic Accuracy of Different Tru-Cut Needle Sizes in Soft Tissue Sarcomas: A Prospective Blinded Study
Source: ClinicalTrials.gov · Last updated 15 Jul 2025
Brief summary (registry, in English)
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 the tumor affect the "matching score"s of biopsies? 3. Do tumor size, tumor depth, tumor subtype and histological grade of the tumor affect the biopsy result concordance and/or diagnostic accuracy measurements? 4. Does needle gauge effect successful tumoral tissue sampling or prediction of histological grade of soft tissue sarcomas?

Who cannot take part
Copied verbatim from ClinicalTrials.gov and grouped by topic. Only the trial team decides who can take part.
Prior treatment
- Patients with a prior diagnosis of the existing mass, coagulation disorders, active infection at the tumor site, a history of previous surgery or radiotherapy to the tumor region, medical conditions contraindicating tru-cut biopsy, or those who did not consent to participate after detailed explanation of the study, were excluded.
Who the study is looking for
- Patients presenting to the Orthopedic Oncology outpatient clinic at Ankara Bilkent City Hospital with suspected or preliminary findings on physical examination suggesting soft tissue sarcoma.
- Patients presenting to the Orthopedic Oncology outpatient clinic at Ankara Bilkent City Hospital with suspected or preliminary findings on radiological imaging suggesting soft tissue sarcoma.
- Patients with soft tissue masses in extremities which require pathological examination
