A study of rib biopsy

A retrospective study of one decade of rib biopsy in four hospitals in Nashville, Tenn, showed 61 biopsies were done in 60 patients. The typical patient was a male in his seventh decade. Preferred operative technique was open biopsy with general anesthesia. One half of the patients had metastatic malignancy; most of the known primary tumors were lung cancer. About one fifth of specimens were normal ribs. Biopsy was done in nine of these because of false-positive scintigraphy. Accurate preoperative chest wall localization is critical in order to minimize intraoperative decision-making problems. Yield of rib biopsy should be increased by more careful clinical observation, including critical evaluation of bone scans, avoiding overinterpretation of physical findings and observing for healing of possible rib fractures.
