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.

PRIMARY OBJECTIVES:
I. To determine maximum tolerated dose (MTD) of TAS-102 when used in combination with liver radioembolization using Yttrium-90 (90Y) resin microspheres.
II. To determine dose limiting toxicities of TAS-102 when used in combination with liver radioembolization using 90Y resin microspheres.
III. To determine the safety (adverse events) of TAS-102/90Y radioembolization combination therapy.
SECONDARY OBJECTIVES:
I. To measure radiographic overall response rate (by Response Evaluation Criteria in Solid Tumors [RECIST] version 1.1) to combination of TAS-102 and radioembolization using 90Y resin microspheres.
II. To measure progression free survival (PFS).
III. To measure hepatic progression free survival (HPFS).
IV. To measure extrahepatic progression free survival (EHPFS).
V. To measure overall survival (OS).
VI. To measure proportion of patients with carcinoembryonic antigen (CEA) response defined as >= 50% decline from baseline (in patients with baseline level >= 20) post combination therapy with TAS-102 and 90Y radioembolization.
OUTLINE: This is a dose escalation study of trifluridine/tipiracil hydrochloride combination agent TAS-102.
Patients receive trifluridine/tipiracil hydrochloride combination agent TAS-102 orally on days 1-5, and 8-13 of cycles 1 and 2, and then on days 1-5 and 8-12 of subsequent cycles. Patients undergo Yttrium-90 microsphere radioembolization on day 3 of cycles 1 and 2. Cycles repeat every 28 days in the absence of disease progression or unexpected toxicity.
After completion of study treatment, patients are followed up at 3, 6, 9, and 12 months.
