epidemiologic study of bone tumorous in Alexandria

ABSTRACT

The records of 368 patients with bone tumours and tumour-like conditions presented to El Hadra University Orthopaedic Hospital over a three-year period were studied. Benign tumours constituted 30.2% and malignant tumours were 25.8% of cases. Tumours with variable behaviour comprised 9.5% of the studied cases. Metastatic tumours and tumour-like lesions comprised 12.2% and 22.3% of cases, respectively. The male to female ratio was 11. The highest age incidence was in the second and third decades of life. All bones were affected except for the carpal bones. The highest incidence was in the femur [36%] followed by the humerus and tibia [16% for each]. Nearly all types of the common bone tumours and tumour-like lesions were encountered. Osteochondroma was the commonest benign tumour while osteosarcoma was the commonest primary malignant bone tumour. Of the tumour-like lesions, simple bone cyst was the commonest. Benign tumours presented more commonly with swelling, while pain and swelling were more common with malignant tumours. Metastatic and tumour-like lesions presented more frequently with pathologic fractures
