Evaluating Fine Needle Aspiration Cytology for Diagnostics of Soft Tissue and Bone Tumours

Cytopathology, EarlyView.
Systematic comparison of needle aspiration cytology and histopathology for 503 tumours in soft tissue and bone showed high concordance (positive predictive value 94%–100%, negative predictive value 83%–89%). In this original study, the authors show that FNAC is a safe and non‐invasive method for diagnosing suspected sarcomas, with the main objective to
