Abstract
Purpose: A total of 2,185 patients with advanced soft tissue sarcomas who had been treated in seven clinical trials investigating the use of doxorubicin- or epirubicin-containing regimens as first-line chemotherapy were studied in this prognostic-factor analysis. Patients and Methods:: Overall survival time (median, 51 weeks) and response to chemotherapy (26% complete response or partial response) were the two end paints. The cofactors were sex; age; performance status; prior therapies; the presence of locoregional or recurrent disease; lung, liver and bone metastases at the rime of entry onto the trial: long time period between the initial diagnosis of sarcoma and entry onto the study; and histologic type and grade. Results: Univariate analyses showed (a) a significant, favorable influence of good performance status, young age, and absence of river metastases on both survival time and response rate, (b) a significant, favorable influence of low histopathologic disease grade on survival time, despite a significantly lower response rate, (c) increased survival time for patients with a long time period between the initial diagnosis of sarcoma and entry onto the study, despite equivalent response rates, and (d) increased survival time with liposarcoma or synovial sarcoma, a decreased survival time with malignant fibrous histiocytoma, a lower response rare with leiomyosarcoma, and a higher response rate with liposarcoma (P < .05 for all log-rank and chi(2) tests). The Cox model selected good performance status (P < .0001), absence of liver metastases (P = .0001), low histopathologic grade (P = .0002), long time lapse since initial diagnosis (P = .0004), and young age (P = .0045) as favorable prognostic factors of survival time. The logistic model selected absence of liver metastases (P .0001), young age(P = .0024), high histopathologic grade (P = .0051), and liposarcoma (P = .0065) as favorable prognostic factors of response race. Conclusion: This analysis demonstrates that for advanced soft tissue sarcoma, response to chemotherapy is no, predicted by the same factors as is overall survival time. This needs to be taken into account in the interpretation of trials assessing the value of new agents for this disease on the basis of response to treatment. J Clin Oncol 17:150-157.
