Biopsy of bone tumours

Area of Science:

• Oncology
• Orthopedic Surgery
• Pathology

Background:

• Bone biopsy is vital for diagnosing bone tumors.
• Chemotherapy necessitates biopsy for treatment evaluation.
• Malignant bone tumors require accurate diagnosis and treatment monitoring.

Purpose of the Study:

• To evaluate the efficacy and complications of bone biopsies.
• To compare open versus drill biopsy techniques.
• To assess fracture risk following bone biopsy in chemotherapy patients.

Main Methods:

• Retrospective analysis of 206 bone biopsies from 136 patients (1978-1982).
• Comparison of open biopsy (99) and drill biopsy (107) techniques.
• Documentation of complications and pathological fractures.

Main Results:

• Overall complication rate was low and not serious.
• Pathological fractures occurred exclusively in patients receiving chemotherapy.
• Open biopsies yielded superior histologic material (98%) compared to drill biopsies (70%).
• 10% of biopsies were non-representative.

Conclusions:

• Bone biopsy is essential for bone tumor diagnosis and treatment assessment.
• Open biopsy is generally superior for obtaining adequate histologic samples.
• Chemotherapy patients, particularly those with long bone malignancies, are at risk for post-biopsy pathological fractures.
