Primary bony chest wall tumours.

A retrospective review of 81 cases of primary chest wall tumours was carried out to analyse their clinical, radiological and surgical features. There were 37 malignant and 44 benign lesions; 72 were found in the ribs and nine in the sternum, of which five were malignant and four benign. Benign tumours of the ribs outnumbered malignant ones by a ratio of 5:4. The distinction between benign and malignant lesions is difficult clinically and radiologically unless cortical destruction and soft tissue swelling are present. The pathological differentiation is also not possible in all cases. All the patients with benign tumours were treated by excision with no recurrences or deaths. The overall 5-year survival for primary malignant chest wall tumours was 43% and 10-year survival was 27%. These were the results of radical en bloc excisions. Based on our experiences we believe that all tumours of the bony chest wall should be considered potentially malignant and wide excision should be performed, not only to provide adequate tissue for diagnosis but also to allow the best chance of cure in malignant lesions.
