Doxorubicin Hydrochloride Liposome and Bortezomib in Treating Patients With Refractory Hematologic Cancer or Malignant Solid Tumor or Metastatic Breast Cancer

RATIONALE: Drugs used in chemotherapy, such as doxorubicin hydrochloride liposome, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Bortezomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving doxorubicin hydrochloride liposome together with bortezomib may kill more cancer cells. PURPOSE: This phase I/II trial is studying the side effects and best dose of bortezomib when given together with doxorubicin hydrochloride liposome and to see how well they work in treating patients with refractory hematologic cancer or malignant solid tumor or metastatic breast cancer.
