Lapatinib Ditosylate and Radiation Therapy in Treating Patients With Locally Advanced or Locally Recurrent Breast Cancer

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.
