Chemotherapy of sarcomas of the limbs by regional perfusion.

From 1957 to 1975, 113 patients with sarcoma of the extremities have been treated with chemotherapy by regional perfusion, either alone or as an adjunct to excisional surgery. Perfusion alone in 54 patients was associated with an early response rate of 83%, but only four patients had complete regression of tumor for longer than three months. When perfusion was followed by immediate or delayed excision, better results were obtained. In 49 Stage I patients and in 24 Stage II patients, cumulative survivals of 66% and 59% were obtained at five years and 66% and 51% at 10 years. The procedure has also been useful in saving functional limbs by converting tumors to operability, and in the palliation of pain and ulceration.
