RATIONALE: Monoclonal antibodies, such as volociximab, 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. Volociximab may also stop the growth of non-small cell lung cancer by blocking blood flow to the tumor. Erlotinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving volociximab together with erlotinib may kill more tumor cells.
