Gemcitabine and Docetaxel in Patients With Unresectable Leiomyosarcoma: Results of a Phase II Trial

Thirty-four patients (median age, 55 years; range, 32 to 74 years) have enrolled. Fourteen had received prior pelvic radiation. Sixteen of 34 patients had progressed after doxorubicin-based therapy; 18 had no prior chemotherapy. Among 34 patients, complete response was observed in three patients and partial response in 15, for an overall response rate of 53% (95% confidence interval, 35% to 70%). Seven patients had stable disease. Fifty percent of patients previously treated with doxorubicin responded. Hematologic toxicity was common (neutropenia: grade 3, 15%; grade 4, 6%; thrombocytopenia: grade 3, 26%; grade 4, 3%), but neutropenic fever (6%) and bleeding events (0%) were rare. The median time to progression was 5.6 months (range, 4 to 10 months).

Gemcitabine plus docetaxel is tolerable and highly active in treated and untreated patients with LMS.
