Paclitaxel and Carboplatin in Treating Patients With Persistent or Recurrent Stage III or Stage IV Uterine Cancer

OBJECTIVES:

- Determine the antitumor activity of paclitaxel and carboplatin in patients with
persistent or recurrent stage III or IV uterine carcinosarcoma.

- Determine the nature and degree of toxicity of this regimen in these patients.

OUTLINE: This is a non-randomized, multicenter study.

Patients receive paclitaxel IV over 3 hours followed by carboplatin IV over 30 minutes on day
1. Courses repeat every 21 days in the absence of disease progression or unacceptable
toxicity.

After completion of study treatment, patients are followed every 3 months for 2 years and
then every 6 months for 3 years.

PROJECTED ACCRUAL: Approximately 14-47 patients will be accrued for this study within 20
months.

DISEASE CHARACTERISTICS:

- Histologically confirmed uterine carcinosarcoma (mixed mesodermal tumor)

- Stage III or IV disease

- Persistent or recurrent disease

- Documented disease progression

- Measurable disease, defined as ≥ 1 unidimensionally measurable lesion ≥ 20 mm by
conventional techniques OR ≥ 10 mm by spiral CT scan

- At least 1 target lesion

- Tumors within a previously irradiated field are not considered target
lesions unless there is documented disease progression

- Ineligible for any higher priority Gynecology Oncology Group (GOG) protocol (i.e., any
active GOG phase III protocol for the same patient population)
