Abstract

INTRODUCTION: In patients with advanced soft tissue sarcoma (STS) treated with chemotherapy, WHO performance status, histologic subtype and histologic grade are known prognostic factors. Although the difference between the subgroups: locally advanced disease only, metastatic disease only and both local and metastatic disease is easily made, its prognostic relevance is thus far unknown. The aim of this EORTC database study was to study the difference in prognosis between these subgroups in patients receiving first-line chemotherapy for advanced STS.

METHODS: A retrospective database analysis was performed on 2473 patients receiving first-line chemotherapy for advanced STS from 12 EORTC sarcoma trials to establish the difference in prognosis for the three subgroups. End-points were overall survival, progression-free survival and overall response rate. Factors studied were age, sex, histologic subtype, histologic grade, WHO performance status, treatment and time since initial diagnosis.

RESULTS: Overall survival differed significantly between patients with locally advanced disease only, with metastatic disease only and with both locally advanced and metastatic disease with a median overall survival of 15.4, 12.9 and 10.6 months, respectively. Similar differences were seen for progression-free survival (5.8, 4.3 and 3.2 months, respectively).

CONCLUSION: This large retrospective database study shows that patients with advanced STSs treated with first-line chemotherapy with locally advanced disease, metastatic disease and both local and metastatic disease have different outcomes. This should be accounted for in future study design, interpretation and comparison of study results and daily practice.
