Phase 2 trial of single agent docetaxel in platinum and paclitaxel-refractory ovarian cancer, fallopian tube cancer, and primary carcinoma of the peritoneum.
OBJECTIVE
Previously reported data have suggested the lack of complete cross-resistance between docetaxel and paclitaxel in ovarian cancer. We wished to evaluate the biological and clinical activity of docetaxel in a patient population with well-characterized platinum and paclitaxel-refractory ovarian cancer.


METHODS
In this single-institution phase 2 trial, 30 women with advanced ovarian cancer whose disease had either failed to respond to primary platinum-paclitaxel chemotherapy or where the cancer had progressed within 3 months of their last treatment with both a platinum agent and paclitaxel were treated with single agent docetaxel (75 mg/m(2) q 3 weeks). Due to a prior history of excessive chemotherapy-induced neutropenia, 3 patients initiated treatment at a dose of 60 mg/m(2).


RESULTS
The median number of courses of docetaxel delivered on this protocol was 3 (range 1-7), with 7 patients requiring dose reductions due to treatment-related side effects. The most common toxicities included grade 4 neutropenia, neutropenic fever, and grade >/=2 fatigue experienced by 9 (30%), 2 (7%), 5 (17%) patients, respectively. Three patients (10%) achieved both an objective response (by CA-125 criteria) and symptomatic improvement (e.g., decrease in pain and ascites). The durations of responses were 3, 4, and 6 months.


CONCLUSIONS
Single-agent docetaxel has modest, but definite activity in patients with well-characterized platinum and paclitaxel-resistant ovarian cancer. Use of this drug should be considered a rational management approach in appropriately selected patients in this clinical setting.
