The role of repeat biopsy in non-diagnostic initial core needle biopsy for soft tissue and bone sarcoma: a systematic review and meta-analysis JF - Mesentery and Peritoneum; Vol 10 (April 30, 2026): Mesentery and Peritoneum (Abstracts for the Sylvester O'Halloran Perioperative Symposium 2026) Y2 - 2026 KW - N2 - Core needle biopsy (CNB) has emerged as the biopsy method of choice for suspected soft tissue or bone sarcoma. Though recent literature suggests high diagnostic accuracy and yield, nondiagnostic CNBs often occur. There is a lack of large-scale data on the role of repeat biopsy in this context. Our aim was to assess the role of repeat biopsy, specifically addressing the diagnostic yield using a large data set. UR - https://map.amegroups.org/article/view/11225
