TAS-102 and Yttrium-90 Microsphere Radioembolization in Treating Patients with Metastatic Colorectal Cancer That Cannot Be Removed by Surgery

Trial Status: complete

This phase I trial studies the side effects and best dose of trifluridine/tipiracil hydrochloride combination agent TAS-102 (TAS-102) and to see how well it works when given together with Yttrium-90 microsphere radioembolization in treating patients with colorectal cancer that has spread to other places in the body (metastatic) and cannot be removed by surgery (unresectable). Drugs used in the chemotherapy, such as trifluridine/tipiracil hydrochloride combination agent TAS-102, 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. Chemoembolization kills tumor cells by carrying drugs directly into blood vessels near tumors and then blocking the blood flow to allow a higher concentration of the drug to reach the tumor for a longer period of time. Chemoembolization may cause fewer side effects in treating patients with colorectal cancer. Giving trifluridine/tipiracil hydrochloride combination agent TAS-102 and Yttrium-90 microsphere radioembolization may work better in treating patients with colorectal cancer.
