Treatment of Epithelioid Sarcoma at the Royal Marsden Hospital

PURPOSE The aim of this study was to assess treatment and outcome with respect to clinical and pathological features. PATIENTS AND METHODS Thirty-nine patients were identified (range 7-66 years, mean 23). Initial treatment comprised local excision in 11 patients and wide excision in 14. Post-operative external beam radiotherapy was prescribed in 22 patients with a total dose of 60 Gy, delivered in two phases. RESULTS The cause-specific survival for the entire group was 79, 63, 56 and 45% at 1, 3, 5 and 10 years, respectively. A distal limb location was associated with a better prognosis than proximal limb location (P = 0.04). CONCLUSIONS Our data favour treatment with wide functional excision followed by radical dose radiotherapy in attempt to minimize risk of local recurrence, especially when primary tumours are bigger than 3 cm. Our data also suggest the same treatment for local recurrence, when technically possible, to avoid amputation.
