title: Prognostic variables for the selection of patients with operable soft tissue sarcomas to be considered in adjuvant chemotherapy trials.
abstract: From 1975 to 1988, 144 patients naive of treatment, with non-metastatic soft tissue sarcoma were treated at Fondation Bergonié by surgery, followed by radiotherapy and without chemotherapy. An analysis of prognostic variables was done on this population to determine patients for whom an adjuvant chemotherapy would be relevant. Prognostic variables in overall survival (OS), metastasis-free survival (MFS), disease-free and local free recurrence survivals were analysed by univariate and multivariate analysis. In multivariate analysis using Cox's model, only tumour depth and tumour grade were significant with the MFS end point, while tumour depth, tumour grade and tumour site were significant when considering OS. A predictive stratification for patients is proposed: a favourable prognostic group with grade 1 tumour or superficial, grade 2 tumour (5-year OS: 97.8%; 5-year MFS: 100%); an intermediate prognostic group with deep, grade 2 tumour or superficial, grade 3 tumour (5-year OS: 58.8%; 5-year MFS: 48.1%); and finally a poor prognostic group with deep, grade 3 tumour (5-year OS: 31.7%; 5-year MFS: 34.1%). Patients in the intermediate and poor prognostic groups who present a high metastatic risk are to be considered for adjuvant chemotherapy trials.
