Isolated limb perfusion for extremity sarcoma

Isolated limb perfusion has been used in patients with extremity sarcomas for over 40 years. In the majority of patients this approach has been employed as a limb-sparing alternative for patients with amputation as their only treatment option. Despite this long history of use in the treatment of patients with extremity sarcomas, many questions remain with respect to the appropriate drug or combination of drugs to be used in the perfusion circuit, the role of hyperthermia in isolated perfusion, and the use of hyperthermic perfusion in the neoadjuvant or adjuvant setting. Although many non-randomized studies have been performed, they suffer from a variety of problems, including small patient numbers, variety of chemotherapeutic agents employed, multiple levels of hyperthermia, and subjective evaluation of what constitutes amputation as a potential treatment option.
