AbstractTen of 16 consecutive patients (63%) with Stages III-IVA soft tissue sarcoma presenting between 1975 and 1978 and treated with surgery, radiotherapy and adjuvant chemotherapy have remained disease-free with a median follow-up of three years (range, 28-68 months). Survival at three years was 86%. However, in the American Joint Committee (AJC) soft tissue sarcoma staging system published in 1977, Grade 3 soft tissue sarcomas were associated with a three-year survival of 35% and almost 90% of the patients destined to fail did so within three years of diagnosis (8). To determine if the observed improvement in survival resulted merely from lesions with favorable prognostic determinants at diagnosis, study patients were matched for stage, histologic type and location of the primary lesion with controls generated from these 1215 carefully reviewed sarcoma patients collected from the data base of the Task Force on Soft Tissue Sarcomas of the AJC. Only control cases whose histology had been reviewed and who had been treated with surgery (with or without radiotherapy) were included in the analysis. Cases survived significantly longer than controls at three years (p less than 0.001) and, in fact, disease-free survival of cases (63%) was superior to overall survival of controls (27%) (p less than 0.01). Our data support the conclusion that patients with high-grade soft tissue sarcoma treated by an experienced multimodality team have a three-year disease-free survival of approximately 63%. The impact of each component of multimodality therapy cannot be determined, and improved survival may result, in addition, from improved diagnostic and staging techniques currently available.
