Short Course Radiation Therapy and Combination Chemotherapy for the Treatment of Stage II-III Rectal Cancer
About
Brief Summary
This phase I trial investigates how well short-course radiation therapy followed by combination chemotherapy works in treating patients with stage II-III rectal cancer. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Chemotherapy drugs, such as leucovorin, fluorouracil, oxaliplatin, and capecitabine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving short-course radiation therapy and combination chemotherapy may reduce the need for surgery and therefore improve quality of life.
