Treatment of recurrent or advanced uterine sarcoma. A randomized trial of doxorubicin versus doxorubicin and cyclophosphamide (a phase III trial of the Gynecologic Oncology Group).

Recurrent or metastatic uterine sarcoma represents an ominous and aggressive form of malignant disease. In an attempt to define a beneficial treatment program, we compared treatment with doxorubicin (A) 60 mg/m2 versus a combination of doxorubicin 60 mg/m2 and cyclophosphamide 500 mg/m (CA), each regimen given every 3 weeks. Of 132 patients entered on study, 104 were eligible; 50 received A and 54 CA. Pretreatment characteristics were similar, and no patient had received prior chemotherapy. The proportion of complete responses (CR) + partial responses (PR) for measurable disease patients was 5 of 26 (19%) for both A and CA. Multivariate analysis done on progression-free interval (PFI) and survival (S) showed CA to be of no benefit over A (PFI, P = 0.22; S, P = 0.55). For both A and CA patients, measurable disease (PFI, P = 0.002; S, P = 0.02, respectively), performance status (PFI, P = 0.004; S, P = 0.0002; respectively), and sites of residual disease (PFI, P = 0.008; S, P = 0.003, respectively) were detected as prognostic variables. Conversely, histologic type, age, and recurrence status (primary versus recurrent at entry) were not prognostic indicators. These data indicate no significant benefit of CA versus A alone in patients with uterine sarcoma.
