Doxorubicin Hydrochloride and Alvocidib in Treating Patients With Metastatic or Recurrent Sarcoma That Cannot Be Removed By Surgery

This phase I trial is studying the side effects and best dose of alvocidib when given with doxorubicin hydrochloride in treating patients with metastatic or recurrent sarcoma that cannot be removed by surgery. Drugs used in chemotherapy, such as doxorubicin hydrochloride and alvocidib, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Alvocidib may also help doxorubicin hydrochloride work better by making tumor cells more sensitive to the drug. Giving more than one drug may kill more tumor cells
