Staging of soft-tissue sarcomas. Prognostic analysis of clinical and pathological features.
In a retrospective study of all 137 patients with soft-tissue sarcoma treated by surgery between 1972 and 1984, the clinical course was related to several host and tumour features, including the Surgical Staging System of Enneking, Spanier and Goodman (1980). Only patients free from metastasis with untreated primary lesions on admission were included. According to the Surgical Staging System, nine tumours were IA, 18 IB, 38 IIA and 72 IIB. Only 12 patients underwent amputation; 125 were treated by local surgery. The mean follow-up time was ten years (minimum five). For the whole series the probability of seven-year survival was 0.65; 42 patients (31%) died from tumour disease. All these had metastases and 24 also had local recurrence. The local recurrence rate was 36%. Multivariate analysis identified large tumour size and high histological grade as significant risk factors for metastatic disease and tumour-related death. Sex, age, tumour site, surgical margin and local recurrence showed no correlation with survival. The prognostic contribution of compartmentality was virtually nil. Histological grade combined with tumour size was found to give better prognostic information than that obtained by the Surgical Staging System.
