Treatment of uterine papillary serous carcinoma with paclitaxel.
OBJECTIVE
The aim of this study was to determine the effectiveness and toxicity of monthly treatment with intravenous paclitaxel for women with advanced or recurrent uterine papillary serous carcinoma (UPSC).


METHODS
Consenting women with histologically confirmed advanced (FIGO stage III or IV) or recurrent UPSC were treated on an Institutional Review Board approved protocol of a 24-h intravenous infusion of 200 mg/m(2) of paclitaxel every 3 weeks. Both measurable and nonmeasurable disease cases were enrolled. Treatment was continued until disease progression, patient intolerance, or (in women with nonmeasurable disease) completion of six courses.


RESULTS
Twenty patients received from 1 to 11 cycles of therapy. Two women died of disease after 1 cycle of therapy and were not evaluable for response. Among 13 women with measurable tumor receiving 2 or more cycles of therapy, 4 had a complete clinical response and 6 had a partial response (objective response rate, 77%). The median time to progression was 7.3 months (range, 2-21 months). All 3 remaining patients with measurable disease had stable disease for a median of 6 months. The 5 patients without evaluable disease received 5 to 6 cycles of adjuvant paclitaxel. Three developed recurrence (range, 4-10 months; median, 7.2 months). Neutropenia was the major toxicity. Eleven of the 20 patients required G-CSF support, and 9 were hospitalized for neutropenic fever. One woman had reversible cardiac symptoms, which might have been related to paclitaxel treatment. At the time of analysis (mean follow-up, 23 months; range, 4.3-59.9 months), 13 women had died of disease, 4 were alive with disease, and 2 were disease free. All 3 disease-free patients had been treated for nonmeasurable advanced stage disease.


CONCLUSIONS
Paclitaxel appears to have excellent activity in the treatment of advanced or recurrent UPSC, an uncommon but aggressive malignancy. Longer survival appears to be more common among women with small-volume disease.
