Doxorubicin Hydrochloride Liposome and Carboplatin in Treating Patients With Recurrent, Stage III, or Stage IV Primary Endometrial Cancer

RATIONALE: Drugs used in chemotherapy, such as doxorubicin hydrochloride liposome 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 chemotherapy) may kill more tumor cells. PURPOSE: This phase II trial is studying how well giving doxorubicin hydrochloride liposome together with carboplatin works in treating patients with recurrent, stage III, or stage IV primary endometrial cancer.
