Summary
This phase II trial studies how well lapatinib ditosylate and radiation therapy work in
treating patients with locally advanced or locally recurrent breast cancer. Lapatinib
ditosylate may stop the growth of tumor cells by blocking some of the enzymes needed for cell
growth. Radiation therapy uses high energy x rays to kill tumor cells. Giving lapatinib
ditosylate together with radiation therapy may be an effective treatment for breast cancer.
