      This phase I trial studies the side effects and best dose of trifluridine/tipiracil&#xD;
      hydrochloride combination agent TAS-102 (TAS-102) when given together with radiation therapy&#xD;
      in treating patients with rectal cancer that has come back, spread to other places in the&#xD;
      body, or cannot be removed by surgery. Drugs used in chemotherapy, such as TAS-102, work in&#xD;
      different ways to stop the growth of tumor cells, either by killing the cells, by stopping&#xD;
      them from dividing, or by stopping them from spreading. Radiation therapy uses high-energy&#xD;
      x-rays to kill tumor cells and shrink tumors. Giving TAS-102 with radiation therapy may kill&#xD;
      more tumor cells.&#xD;

      PRIMARY OBJECTIVES:&#xD;
&#xD;
      I. To determine the maximum tolerated dose and dose-limiting toxicity of TAS-102 when&#xD;
      administered in combination with concurrent radiation therapy in patients with locally&#xD;
      recurrent or metastatic rectal cancer.&#xD;
&#xD;
      SECONDARY OBJECTIVES:&#xD;
&#xD;
      I. To determine the overall response rate (ORR) to concurrent TAS-102 and radiation therapy&#xD;
      in patients with locally recurrent or metastatic rectal cancer.&#xD;
&#xD;
      II. To determine the progression-free survival (PFS) in patients with locally recurrent or&#xD;
      metastatic rectal cancer who receive concurrent TAS-102 and radiation therapy.&#xD;
&#xD;
      III. To determine the overall survival (OS) in patients with locally recurrent or metastatic&#xD;
      rectal cancer who receive combined TAS-102 and radiation therapy.&#xD;
&#xD;
      IV. To determine quality of life (QoL) among patients with locally recurrent or metastatic&#xD;
      rectal cancer who receive concurrent TAS-102 and radiation therapy.&#xD;
&#xD;
      V. To determine the number of patients who are able to undergo surgical resection following&#xD;
      concurrent treatment with TAS-102 and radiation therapy. Of this subset of patients, the&#xD;
      investigators will assess rates of pathologic complete response (pCR), tumor regression grade&#xD;
      (TRG) and rates of R0 resection.&#xD;
&#xD;
      OUTLINE: This is a dose-escalation study of trifluridine/tipiracil hydrochloride combination&#xD;
      agent TAS-102.&#xD;
&#xD;
      Patients receive trifluridine/tipiracil hydrochloride combination agent TAS-102 orally (PO)&#xD;
      twice daily (BID) and undergo radiation therapy in 10 fractions on days 1-5 and 8-12 in the&#xD;
      absence of disease progression or unacceptable toxicity.&#xD;
&#xD;
      After completion of study treatment, patients are followed up at 4-6 weeks, and at 3 and 6&#xD;
      months.&#xD;

This phase I trial studies the side effects and best dose of trifluridine/tipiracil
      hydrochloride combination agent TAS-102 (TAS-102) when given together with radiation therapy
      in treating patients with rectal cancer that has come back, spread to other places in the
      body, or cannot be removed by surgery. Drugs used in chemotherapy, such as 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. Radiation therapy uses high-energy
      x-rays to kill tumor cells and shrink tumors. Giving TAS-102 with radiation therapy may kill
      more tumor cells.
PRIMARY OBJECTIVES:

      I. To determine the maximum tolerated dose and dose-limiting toxicity of TAS-102 when
      administered in combination with concurrent radiation therapy in patients with locally
      recurrent or metastatic rectal cancer.

      SECONDARY OBJECTIVES:

      I. To determine the overall response rate (ORR) to concurrent TAS-102 and radiation therapy
      in patients with locally recurrent or metastatic rectal cancer.

      II. To determine the progression-free survival (PFS) in patients with locally recurrent or
      metastatic rectal cancer who receive concurrent TAS-102 and radiation therapy.

      III. To determine the overall survival (OS) in patients with locally recurrent or metastatic
      rectal cancer who receive combined TAS-102 and radiation therapy.

      IV. To determine quality of life (QoL) among patients with locally recurrent or metastatic
      rectal cancer who receive concurrent TAS-102 and radiation therapy.

      V. To determine the number of patients who are able to undergo surgical resection following
      concurrent treatment with TAS-102 and radiation therapy. Of this subset of patients, the
      investigators will assess rates of pathologic complete response (pCR), tumor regression grade
      (TRG) and rates of R0 resection.

      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 (PO)
      twice daily (BID) and undergo radiation therapy in 10 fractions on days 1-5 and 8-12 in the
      absence of disease progression or unacceptable toxicity.

      After completion of study treatment, patients are followed up at 4-6 weeks, and at 3 and 6
      months.

description: Responses will be summarized by simple descriptive summary statistics delineating complete and partial responses as well as stable and progressive disease in this patient population.
measure: Incidence and severity of adverse events graded according to the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 4.0
time frame: Up to 6 months
description: Will be tabulated and summarized.
measure: Incidence of toxicities graded according to the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 4.0
time frame: Up to 6 months
description: Overall toxicity incidence as well as toxicity profiles by dose level and patient will be explored and summarized. Frequency distributions, graphical techniques and other descriptive measures will form the basis of these analyses.
measure: Median progression free survival
time frame: Up to 6 months
description: Kaplan Meier curves will be utilized to estimate the median progression free survival in the expansion cohort.
measure: Number of patients that make it to surgery
time frame: Up to 6 months
description: Will assess rates of pathologic complete response (pCR), tumor regression grade (TRG), and rates of R0 resection.
measure: Overall survival
time frame: Up to 6 months
description: Kaplan Meier curves will be utilized to estimate the overall survival in the expansion cohort.
measure: Quality of life (QoL) as assessed by the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30)
time frame: Up to 6 months
description: Descriptive statistics of testing measures, including patients' pain and quality of life scores, will be calculated and correlated to treatment dose and response.
measure: Time to progression
time frame: Up to 6 months
description: Will be summarized descriptively.
measure: Time to treatment failure
time frame: From registration to documentation of progression, unacceptable toxicity, or refusal to continue participation by the patient, assessed up to 6 months
description: Will be summarized descriptively.
measure: Time until any treatment related toxicity
time frame: Up to 6 months
description: Will be summarized descriptively.
measure: Time until hematologic nadirs (absolute neutrophil count [ANC], platelets, hemoglobin)
time frame: Up to 6 months
description: Will be summarized descriptively.
measure: Time until treatment related grade 3+ toxicity
time frame: Up to 6 months
description: Will be summarized descriptively.
