Biopsy Needle Size in Soft Tissue Sarcoma

NCT07066774 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 30

Last updated 2025-07-15

No results posted yet for this study

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 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?

Conditions

  • Soft Tissue Sarcoma of the Limb

Interventions

DIAGNOSTIC_TEST

Tru-cut Biopsy with 14 G Needle

Each participant underwent Percutaneous Tru-cut Biopsy with 14G tru-cut needle in a single session procedure. There are no studies to our knowledge to compare samples from the same tumor

DIAGNOSTIC_TEST

Tru-cut Biopsy with 16G tru-cut needle

Each participant underwent Percutaneous Tru-cut Biopsy with 16 tru-cut needle in a single session procedure. There are no studies to our knowledge to compare samples from the same tumor

DIAGNOSTIC_TEST

Tru-cut Biopsy with 18G tru-cut needle

Each participant underwent Percutaneous Tru-cut Biopsy with 18G tru-cut needle in a single session procedure. There are no studies to our knowledge to compare samples from the same tumor
