Abstract
Fifty-one patients with soft tissue sarcoma of the upper limb were studied to identify risk factors for local recurrence and survival. More than half (53 per cent) of the patients referred had locally recurrent disease. The flexor aspect of the forearm was the most common site of origin. The majority of patients were managed by a combination of conservative surgery and radical radiotherapy. Wide or radical excision was achieved in 49 per cent of cases. One-third of patients required partial resection of bone or neurovascular structures; 75 per cent of them had presented with local recurrence after treatment elsewhere. Skin grafts and flap repairs were used more often in patients with local recurrence (P = 0.013) and 20 (74 per cent) of those referred with locally recurrent disease have had no further local relapse. The overall 5-year survival rate of 80 per cent (95 per cent confidence interval 61–90 per cent) supports a policy of conservative surgery. Factors associated with a lower survival rate were deep fixation, origin in the flexor aspect of the forearm, and previous local recurrence. Deep fixation was also associated with an increased risk of local recurrence. Referral to a specialist unit at the time of initial presentation may result in lower rates of local recurrence and may improve the survival rate.
