Summary

Rib biopsy is a valuable diagnostic tool, particularly for metastatic malignancy. Careful patient selection and imaging review can improve the diagnostic yield of this procedure.

Area of Science:

  • Thoracic surgery
  • Surgical pathology
  • Diagnostic imaging

Background:

  • Rib biopsies are performed to diagnose various chest wall conditions.
  • Metastatic malignancy is a common indication for rib biopsy, often originating from lung cancer.

Purpose of the Study:

  • To analyze a decade of rib biopsy data from four Nashville hospitals.
  • To identify patient demographics, common indications, and outcomes.
  • To provide recommendations for improving the diagnostic yield of rib biopsy.

Main Methods:

  • Retrospective chart review of 61 rib biopsies performed on 60 patients over ten years.
  • Analysis of patient demographics, operative techniques, primary tumor types, and specimen findings.
  • Review of indications for biopsy, including false-positive scintigraphy.

Main Results:

  • The typical patient was a male in his seventh decade.
  • Open biopsy under general anesthesia was the preferred technique.
  • Malignant metastatic disease was present in 50% of patients, with lung cancer being the most frequent primary tumor.
  • 19% of specimens showed normal ribs, with nine biopsies performed due to false-positive bone scans.

Conclusions:

  • Accurate preoperative chest wall localization is crucial for successful rib biopsy.
  • Improving the diagnostic yield requires meticulous clinical evaluation, critical assessment of bone scans, and avoiding overinterpretation of physical findings.
  • Observing for rib fracture healing can also inform diagnostic decisions.
