OBJECTIVES:

• Determine the antitumor activity of flavopiridol in patients with recurrent or persistent endometrial carcinoma.
• Determine the nature and degree of toxicity of this drug in these patients.

OUTLINE: This is a multicenter study.

Patients receive flavopiridol IV over 1 hour on days 1-3. Treatment repeats every 21 days for at least 2 courses in the absence of disease progression or unacceptable toxicity.

Patients are followed every 3 months for 2 years, every 6 months for 3 years, and then annually thereafter.

PROJECTED ACCRUAL: A total of 19-51 patients will be accrued for this study within 10-24 months.

DISEASE CHARACTERISTICS:

• Histologically confirmed primary endometrial carcinoma

  • Recurrent or persistent disease
  • Refractory to curative therapy or established treatment

• Previously treated with only 1 prior cytotoxic chemotherapy regimen (either single agent or combination therapy) for endometrial carcinoma

  • Initial treatment may include high-dose, consolidation, or extended therapy administered after surgical or non-surgical assessment

• At least 1 unidimensionally measurable lesion

  • At least 20 mm by conventional techniques OR
  • At least 10 mm by spiral CT scan
  • At least 1 target lesion outside previously irradiated field
• Ineligible for higher priority Gynecologic Oncology Group (GOG) protocol, defined as any active GOG phase III protocol for the same patient population

• At least 6 months since prior re-vascularization procedures (e.g., coronary artery bypass graft, carotid endarterectomy or bypass, or angioplasty with or without stents)

Other:

• At least 3 weeks since other prior therapy for endometrial carcinoma
• At least 6 months since prior thrombolytic procedures
• No prior cyclin-dependent kinase inhibitors
• No prior anticancer therapy that would preclude study
