Sarcoma developed in irradiated area: Preliminary results of the SARI trial

Radiotherapy and surgery are the two main pillars of the locoregional treatment of cancer. The risk of second malignancy is better evaluated and constitutes a major issue regarding radioprotection of the patients. Among malignant disease observed in the surviving irradiated patients, the occurrence of sarcoma is a rare event but associated with a poor outcome since the 5 year overall survival is estimated at 10 to 35 %. The SARI protocol, written in 2011, included 120 patients and 240 controlled patients, irradiated in the same conditions but without sarcoma observed during the follow up. The main objective was to identify the clinical and biological factors associated with the occurrence of such a complication. The secondary objective was to identify the dosimetric characteristics of the treatment of the primary. Preliminary results will be presented during the 2016 meeting of the French radiation oncology society. (C) 2016 Societe francaise de radiotherapie oncologique (SFRO).
