In the present study, the outcome, patterns of local recurrence and survival, as well as prognostic factors, were evaluated in patients surgically treated for soft tissue sarcomas. Between January 1979 and July 1993, 316 consecutive patients were referred to the Sarcoma Centre in Aarhus with localised malignant soft tissue sarcoma of the extremities or trunk. If possible, the patients were treated with a limb-sparing resection, primarily by use of a wide excision. 50 patients received adjuvant radiotherapy. There were 161 men (51%) and 155 women (49%) median age 56 years (range 1-94 years). 94 patients (30%) had tumours in the trunk, including shoulder and buttock lesions, 163 (52%) in the lower extremity and 59 (19%) in the upper extremity. 52 patients (16%) had grade 1 tumour, 60 (19%) grade 2 and 204 (65%) grades 3A-3B. The 5-year local recurrence rate was 18% and the 5-year survival rate was 75%. Multivariate analysis indicated the following variables as independent unfavourable factors for local recurrence: extracompartmental location, histological high grade, local excision, no adjuvant radiotherapy and intralesional/marginal excision. Independent unfavourable factors for survival were advanced age, extracompartmental location, histological high grade, lower extremity location and large tumour size. If the variable local recurrence was included in the analysis, it was found to have a very strong influence on survival. Based on these variables, a prognostic model was developed.
