    Abstract:
    BACKGROUND: Tumor necrosis factor-alpha (TNFalpha)-based hyperthermic isolated limb perfusion (HILP) is routinely carried out at most oncological institutions in the treatment of locally advanced soft tissue limb sarcoma (STS), employing high TNFalpha dosages. After a phase I-II study, the SITILO (Italian Society of Integrated Locoregional Therapies in Oncology) centers began to employ the lower dose of 1 mg of TNFalpha. The aim of this paper is to report on the results obtained in 75 patients with limb-threatening STS treated with a low TNFalpha dose and doxorubicin (Dx). PATIENTS AND METHODS: HILP with TNFalpha (at a dosage of either <or=1 mg or >1 mg) and Dx was administered to 75 patients with limb-threatening STS: 37 males and 38 females; median age 50 years; tumor in the lower and upper limbs in 58 and 17 patients, respectively; primary and recurrent tumors in 45 and 30 patients, respectively. Most tumors (77%) were high grade. Tumor resection was carried out 6 to 8 weeks after HILP. RESULTS: The grade of limb toxicity was mild to moderate in the vast majority of patients (76%). Grades IV and V were observed, but only when high muscle temperatures were recorded and high TNFalpha dosages were employed. Systemic toxicity was also mild to moderate and there were no postoperative deaths. Complete and partial tumor responses were 34% and 48%, respectively, with an overall response of 82% . Limb sparing surgery was carried out in 85.3% of patients. At a median follow-up of 28 months, 16 recurrences (21.3%) were recorded, with a 5-year locoregional disease-free survival of 63% . The 5-year disease-free survival and overall survival were 36.7% and 61.6%, respectively. CONCLUSION: HILP with 1 mg of TNFalpha is an effective neoadjuvant therapy resulting in a high rate of limb sparing in limb-threatening STS, with acceptable local reactions and negligible systemic toxicity.
