Percutaneous needle biopsy in the diagnosis of soft tissue tumors A potent tool in underdeveloped countries

摘要

Fine needle aspiration biopsy is a useful tool in the pre-operative evaluation and grading of soft tissue tumors, and offer patients the advantage of neo-adjuvant/ adjuvant chemotherapy or radiotherapy. Our study aimed at correlating the clinical, radiological and cytological findings of benign and malignant tumors of soft tissues and evaluating the usefulness of percutaneous needle biopsy as a diagnostic tool. Out of a total of 136 cases of soft tissue tumors aspirated, 110 were benign and 26 malignant. Upper extremity including axilla was the most frequently involved site of benign soft tissue tumors with 37 cases, while the lower extremity including inguinal area was the most common site of malignant soft tissue tumors with 10 cases. Sensitivity and specificity of cytological diagnosis was 77.8 and 92.3%, respectively, while the positive and negative predictive value was 87.5 and 86.7%, respectively, with the diagnostic accuracy being 86.9%.
