Phase II study of paclitaxel as salvage treatment in advanced endometrial cancer
1Department of Obstetrics and Gynecology, S. Gerardo Hospital, University of Milan, Monza, Italy.
Objective:
To evaluate the antitumour activity of paclitaxel in patients with endometrial cancer pretreated with cisplatin, doxorubicin and cyclophosphamide (PAC).
Materials And Methods:
Eligible patients had complete initial surgery, expected survival > or = 3 months, performance status < or = 1, measurable or evaluable disease. Paclitaxel was given over three hours at the dose of 175 mg/m2, repeated every 3 weeks. Tumour response was first evaluated after 3 cycles. A maximum of 10 cycles was given in responders.
Results:
19 patients entered the study and a total of 105 cycles were administered. Complete and partial responses were achieved in 2 and 5 patients, respectively, for an overall response rate of 37% (95% CI: 16%-62%). The response rate in patients refractory to platinum was 22%. One patient is alive without evidence of disease 16 months after the start of treatment. The most common side effects were mild to moderate myalgia and peripheral neuropathy, which occurred in 31% and 47% of patients, respectively. In only 1 patient treatment had to be discontinued because of severe myalgia.
Conclusion:
Paclitaxel is active in patients with endometrial cancer pretreated with PAC. Further studies with paclitaxel incorporated in the initial treatment for advanced disease are warranted.
