RATIONALE: 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. Erlotinib and everolimus may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Bevacizumab and everolimus may also block blood flow to the tumor. Giving everolimus and erlotinib together with bevacizumab may kill more tumor cells.
