Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells. Colony-stimulating factors such as filgrastim or pegfilgrastim may increase the number of immune cells found in bone marrow or peripheral blood and may help a person's immune system recover from the side effects of chemotherapy. This phase II trial is studying how well combination chemotherapy plus filgrastim or pegfilgrastim works in treating patients with recurrent or persistent cancer of the uterus.
