title: Isolated limb perfusion with cisplatin and doxorubicin for locally advanced soft tissue sarcoma of an extremity.
abstract: OBJECTIVE
  To identify independent adverse clinico-pathological factors for disease-free and overall survival in patients undergoing isolated limb perfusion (ILP) with cisplatin and doxorubicin for locally advanced soft tissue sarcoma (STS) of an extremity.
  
  
  METHODS
  A retrospective analysis was carried out, using a univariate method and a multivariate analysis, to look at the patient, tumour and treatment associated with prognostic factors in 37 patients with locally advanced STSs of the limbs who underwent ILP with cisplatin and doxorubicin. Patient's age, gender, presenting status, tumour location, tumour grade, tumour stage according to TNM classification, tumour size and radiotherapy (RT) were analysed. Survival curves were calculated according to the Kaplan-Meier method. A Cox proportional hazard model was used to indicate which factors related to overall survival and the recurrence-free interval after ILP.
  
  
  RESULTS
  No major systemic toxicity was seen. Regional toxicity was limited. Limb salvage was achieved in 94.6% of the patients. The estimated 5-year overall and disease-free survival rates were 62% and 54%, respectively. It was found that tumour stage, tumour grade, presenting status, RT and tumour size were associated with cumulative overall survival when the Kaplan-Meier method was applied (P<0.05). By Cox proportional hazards model, only tumour grade (P=0. 0254) was found to have significant influence on overall survival; however, tumour stage (P=0.0157) and RT (P=0.0014) were related to disease-free survival.
  
  
  CONCLUSIONS
  ILP and delayed excision followed by RT achieves good limb salvage rates and may improve survival.
