Neoadjuvant therapy in soft-tissue sarcomas is still a controversial issues regarding indications, patients selection and treatment protocols. In the last fifteen years (1990–2005) at our Institution more than 600 patients affected by soft tissue sarcomas of the limbs and superficial trunk were surgically treated. Among these patients, 49 received preoperative chemotherapy (epirubicin plus ifosfamide, according to Italian Sarcoma Group protocol), associated to preoperative conventional external beam radiationtherapy in 36 cases (73.5%). The histologic types were liposarcoma (30,6%), synovial sarcoma (20,4%), fibrosarcoma (16,3%), pleomorphic sarcoma or malignant fibrous histiocitoma (12,1%), leiomyosarcoma (8,2%), other histotypes (12,1%). Tumor size was 10 cm or larger in 21 cases, 6 to 9 cm in 23 patients and 5 cm or smaller in 5 cases. Neoplasms were high-grade (Broders grade 3 or 4) in all cases but five. After neoadjuvant treatment we performed a limb-sparing surgical excision of the tumor in 47 patients (96%), while a primary amputation of the limb was necessary in only two cases (4.1%). A vascularized miocutaneous flap was used in 8 cases, and adequate surgical margins were achieved in more than 70% of the cases. Postoperative chemotherapy was given in 26 cases (53%), postoperative radiotherapy just in 5 (10%). We report the outcome data on these 49 cases, regarding overall survival, local or distant relapse, local and systemic complications, early and long-term limb salvage rate.

Abstract
Neoadjuvant therapy in soft-tissue sarcomas is still a controversial issues regarding indications, patients selection and treatment protocols. In the last fifteen years (1990–2005) at our Institution more than 600 patients affected by soft tissue sarcomas of the limbs and superficial trunk were surgically treated. Among these patients, 49 received preoperative chemotherapy (epirubicin plus ifosfamide, according to Italian Sarcoma Group protocol), associated to preoperative conventional external beam radiationtherapy in 36 cases (73.5%). The histologic types were liposarcoma (30,6%), synovial sarcoma (20,4%), fibrosarcoma (16,3%), pleomorphic sarcoma or malignant fibrous histiocitoma (12,1%), leiomyosarcoma (8,2%), other histotypes (12,1%). Tumor size was 10 cm or larger in 21 cases, 6 to 9 cm in 23 patients and 5 cm or smaller in 5 cases. Neoplasms were high-grade (Broders grade 3 or 4) in all cases but five. After neoadjuvant treatment we performed a limb-sparing surgical excision of the tumor in 47 patients (96%), while a primary amputation of the limb was necessary in only two cases (4.1%). A vascularized miocutaneous flap was used in 8 cases, and adequate surgical margins were achieved in more than 70% of the cases. Postoperative chemotherapy was given in 26 cases (53%), postoperative radiotherapy just in 5 (10%). We report the outcome data on these 49 cases, regarding overall survival, local or distant relapse, local and systemic complications, early and long-term limb salvage rate.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
