Circadian-timed combination doxorubicin-cisplatin chemotherapy for advanced endometrial carcinoma. A phase II study of the Gynecologic Oncology Group.
Patients with advanced or recurrent endometrial cancer of any cell type having measurable disease have been entered into this study to determine the effectiveness and toxicity of circadian-timed doxorubicin-cisplatin chemotherapy. This Phase II study involved no randomization with treatment initiated with doxorubicin 60 mg/m2 over 30 minutes at 6:00 a.m., followed by cisplatin 60 mg/m2 over 30 minutes at 6:00 p.m. every 28 days. Treatment was continued for eight cycles or to a maximum tolerable doxorubicin dose of 480 mg/m2 for patients without progression. Thereafter, responders continued on cisplatin alone. A review of 30 evaluable patients showed 6 (20%) complete responses, 12 (40%) partial responses, and 7 (23%) with stable disease. The number of treatment courses ranged from 2 to 14 with a median of 6.5. the median white blood cell nadir for the 27 patients experiencing leukopenia was 1,600/mm3 (range: 300-3,600/mm3) For the 16 patients experiencing thrombocytopenia the median nadir was 48,500/mm3 (range: 8,000-138,000/mm3). There were no treatment-related deaths. Circadian-timed delivery of doxorubicin-cisplatin chemotherapy was reasonably well tolerated and demonstrated notable response rates in patients with advanced or recurrent endometrial carcinoma.
