title: Multimodality treatment of locally advanced soft-tissue sarcomas of the extremities.
abstract: BACKGROUND
  Adjuvant radiotherapy (RTE) still has a fundamental role as a post-operative treatment of locally advanced soft tissues sarcomas of the extremities. Moreover the employment of combined modalities in locally advanced soft tissues sarcomas of the extremities allow to maximize the chance of local cure even in difficult presentation cases, and possibly improve survival, especially in high-risk disease patients. In patients with sarcomas of the extremities in which definitive surgery has not been radical (with positive or "close" margins) radiotherapy can improve the results in terms of Disease Free Survival (DFS) and, together with chemotherapy, of Overall Survival (OS). We recommend radiotherapy in case of deep tumor location, inadequate surgical margins and grade 3 tumour; for positive or "marginal (or close)" excision (that means inadequate surgery) or in selected patients with a bad prognosis, we believe that a multidisciplinary approach can be preferable.
  
  
  BACKGROUND
  Adjuvant radiotherapy (RTE) still has a fundamental role as a post-operative treatment. In patients with sarcomas of the extremities in whom definitive surgery has been or not radical (positive or "close" margins), radiotherapy with chemotherapy can improve the results in terms of Disease Free Survival (DFS) and Overall Survival (OS), while RTE alone seems to improve local control.
  
  
  METHODS
  From 1/2000 to 12/2005 we treated 34 patients affected by locally advanced sarcomas of the upper or lower extremities with radiotherapy (doses ranging from 54 to 66 Gy) and chemotherapy in 18/34 with an adjuvant scheme that consisted in Epirubicine (120 mg/m(2)) plus Ifosfamide (7000-9000 mg/m(2)).
  
  
  RESULTS
  Disease Free Survival (DFS) and the Overall Survival (OS) rates were 76% and 82%, respectively. Eighteen patients developed one or more long-term side effects. Most of these complications were mild: all patients experienced only erithema, edema, local sclerosis or moderate pain.
  
  
  CONCLUSIONS
  Radiotherapy has an important role as a post-operative treatment also when surgery was non-radical. It improves local control more in patients with high-grade sarcomas of the extremity with positive or close margins. It is still difficult to assess the role of adjuvant chemotherapy.
