 RATIONALE: Drugs used in chemotherapy, such as docetaxel, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Thalidomide may stop the growth of non-small cell lung cancer by blocking blood flow to the tumor. Thalidomide may also help docetaxel work better by making tumor cells more sensitive to the drug. Giving docetaxel together with thalidomide may kill more tumor cells.
