Accuracy of Histology and Malignancy Grade between Preoperative Biopsy and Surgical Specimens in Primary Retroperitoneal Sarcoma. A Study from the Prospective Retroperitoneal Sarcoma Registry (Resar)
While preoperative biopsy for RPS provides satisfactory histologic accuracy, tumor grade is frequently underestimated. This diagnostic inaccuracy may impact treatment decisions, particularly regarding preoperative therapies. Incorporating additional diagnostic factors may improve the accuracy of preoperative assessment.
