Summary
Brief summary (as posted)
This phase I/II trial is studying the side effects of giving paclitaxel together with radiation therapy with or without trastuzumab and to see how well it works to kill any remaining tumor cells in patients who have undergone surgery for bladder cancer. Drugs used in chemotherapy, such as paclitaxel, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Radiation therapy uses high-energy x-rays to kill tumor cells. Paclitaxel may also make tumor cells more sensitive to radiation therapy. Monoclonal antibodies, such as trastuzumab, 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. Giving paclitaxel together with radiation therapy and trastuzumab may kill more tumor cells. Giving these treatments after surgery may kill any remaining tumor cells.
