Abstract
Introduction and Aim: This project reports on patients treated with malignant fibula pathology at the London Bone Tumor Service with the aim of reporting on the prognosis for such patients.
Method and Results: Over a 15-year period, The London Bone Tumor Service has treated 39 patients with malignant fibula pathology: Osteosarcoma (23), Ewing’s sarcoma (16). Proximal fibula pathology was more common (29), distal (five) and diaphyseal (five). Thirty-two patients were treated with wide local excision initially, one below knee amputation, three above knee amputations, two were not fit for surgery and two died while receiving chemotherapy. Two patients required subsequent above knee amputations and one patient a hip disarticulation. Relapse was very common in proximal fibula osteosarcoma. Only 7/23 patients avoided both metastasis and local recurrence.
The five-year survival rate of osteosarcoma of the proximal fibula is 33%, distal fibula 100% and diaphyseal 100%. Ewing’s sarcoma of the proximal fibula is 40%, diaphyseal 50% and distal fibula 100%.
Conclusion: Despite relatively early presentation of symptoms, the prognosis of proximal fibula osteosarcoma and Ewing’s remains poor. Unlike the prognosis of both distal and diaphyseal pathology, which remains excellent.
