Abstract
Introduction: Malignant tumours of the foot and ankle are rare. The aim of the study was to document one of the largest series of malignant tumours affecting the foot and ankle and to assess the outcomes following limb salvage and amputation.
Methods: The study was a retrospective review of the patients with a malignant tumour of the foot and ankle. Demographic details, diagnosis, treatment and outcomes were retrieved from the electronic patient records containing information on over 20 000 patients seen over a 25 year period.
Results: Two hundred and twenty five patients had malignant tumours affecting the foot and ankle. It was common in the fifth decade (35 patients). The mean age was 46 years. The commonest diagnosis was synovial sarcoma (40 patients) followed by chondrosarcoma (23 patients) and Ewing’s sarcoma (21 patients). The mean tumour size was 5.6 cm (0.8 to 17.5 cm). 82 patients (37%) underwent an unplanned excision and 13% (29 patients) presented with metastases at diagnosis. Primary bone tumours were 28% (64 patients), soft tissue sarcomas were 62% and metastatic tumours were 8% while lymphoreticular malignancies were (1%). Limb salvage was possible in 71% (156 patients). 29% (65 patients) had a below knee amputation. 7% (15 patients) had a local recurrence. The 5 years survival was 63%. The 5 years survival for the patients who had limb salvage was 68% compared with 54% for the patients who had an amputation (p 0.03).
Conclusion: Though amputation can provide better local control, limb salvage surgery improves survival.
