Summary
RATIONALE: Temsirolimus may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Monoclonal antibodies, such as bevacizumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Bevacizumab may also stop the growth of tumor cells by blocking blood flow to the tumor. Giving temsirolimus together with bevacizumab may be a better way to block tumor growth.
PURPOSE: This phase I/II trial is studying the side effects and best dose of temsirolimus when given together with bevacizumab and to see how well it works in treating patients with hormone-resistant metastatic prostate cancer that did not respond to chemotherapy.
