Amputation of the lower limb as palliative treatment for debilitating musculoskeletal cancer

Limb sparing surgery has replaced amputation surgery for treating sarcomas of the lower limb in most cases. Wide resection followed by postoperative radiation therapy can achieve acceptable local control and survival rates in patients with bone and soft-tissue sarcomas of the lower limb. Recurrent or persistent disease constitutes a major oncological problem. Local symptoms such as agonizing pain, fractures, tumor fungation, inability to walk and inability to maintain daily activities, further impair the patient's quality of life. In this clinical set-up palliative amputation of the limb should be considered. Fourteen patients with soft-tissue or bone sarcomas underwent palliative major amputation. The procedures included: hemipelvectomy, hip disarticulation, knee disarticulation, above or below-knee amputation. Local control of the disease and pain, and improvement of the performance status were observed in 13 evaluable patients. The mobility was restored in 13/14 patients. The median survival following the procedure was 9 months. There was only one case of immediate post-operative death. Severe phantom pain was not reported by any of the patients. Quality of life was reported to be improved by two-thirds of the patients. We found palliative major amputation surgery worth-performing in low-performance status cancer patients with locally advanced disease of the lower limb.
