RATIONALE: Drugs used in chemotherapy, such as paclitaxel and carboplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination therapy) may kill more tumor cells.

PURPOSE: This phase II trial is studying how well giving paclitaxel together with carboplatin works 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.

Ages Eligible for Study:  18 Years and above,  Genders Eligible for Study:  Both
