Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Inclusion Criteria:

  • Histologically or cytologically confirmed locally residual or recurrent cancer of the rectum or anus
  • Prior pelvic EBRT

    • Eligible for infusional 5-FU or capecitabine
    • Will not undergo surgery for the study disease
    • Able to receive HDR brachytherapy ANC ≥ 1.5 cells/mm3 and PLT ≥100,000/mm3
  • Adequate Renal function: Creatinine <1.5 x the upper limit of normal (ULN) or calculated creatinine clearance of ≥ 50cc/min
  • Adequate Hepatic functions: Bilirubin less than 1.5 mg/dL; (except in patients with Gilbert's Syndrome, who must have a total bilirubin less than 3.0 mg/dL)

Exclusion Criteria:

  • Women who are pregnant.

Male subjects must also agree to use effective contraception during the treatment period and until 1 year after the completion of brachytherapy.
  • Patients with any other concurrent medical or psychiatric condition or disease which, in the investigator's judgment, would make them inappropriate candidates for entry into this study.
  • Patients on concurrent anti-cancer therapy other than that allowed in the study.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: endorectal brachytherapy, concurrent chemo and questionnaires
This is a phase I, dose-escalation study to evaluate the safety of endorectal brachytherapy with concurrent capecitabine or 5-fluoruracil (5-FU) in the management of locally recurrent/residual rectal or anal cancer in patients who have received pelvic external beam radiation therapy (EBRT) +/- chemotherapy. We will use magnetic resonance imaging (MRI) with dynamic contrast enhancement (DCE) and diffusion weighted imaging (DWI) series to contribute to the assessment of tumor response.
Radiation: endorectal brachytherapy
Patients will receive 3 fractions of endorectal brachytherapy, each spaced apart by 7 days (+/- 1 day). The three dose tiers will be 1500cGy (500cGy per fraction), 1800cGy (600cGy per fraction), and 2100cGy (700cGy per fraction).
Drug: concurrent capecitabine or 5-FU

Patients will receive 500 mg and 150 mg oral tablets of capecitabine for the prescribed dose of 825 mg/m2 BID, morning and evening (total daily dose of 1650 mg/m2 ). Dosages will be rounded to the nearest 150 mg or 500 mg. Tablets should be swallowed with water within 30 minutes after a meal. Capecitabine will be started on the Monday of the first week of brachytherapy (day 1) and taken on weekdays (Monday through Friday) during weeks of brachytherapy only.

Administration of 5-FU should be only by the intravenous route taking care to avoid extravasation. Patients will receive 225 mg/m2/day, as a continuous venous infusion by a portable pump for the 3 weeks of treatment. The infusional 5-FU will be exchanged every 7 days.

Behavioral: Questionnaires
Patients should complete the 2 quality of life questionnaires during their follow-up appointments. If they are unable to be seen in follow-up, they may complete the questionnaires at home and email or mail them back to the investigator. Should there be any incomplete or ambiguous answers, a follow-up phone call will be made by a member of the research team for clarification. Additionally, if the questionnaires have not been returned within 3 weeks after the time when they are due, a member of the research team will call the patient, and the questions will be completed over the phone.

  • Quality of Life Assessment
  • Bowel Function Assessment

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
maximum tolerated dose (MTD)
Time Frame: 1 year
will employ a standard 3+3 dose-escalation scheme. Patients will be accrued to the study in cohorts of 3. An initial cohort of 3 patients will be treated to each dose. The dose level will be escalated if none of the 3 patients exhibits any DLT within 90 days of completion of brachytherapy. Dose escalation will not take place until every patient in the prior dose cohort has been monitored for 90 days.
1 year

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
tumor response
Time Frame: 3, 6, and 12 months
MRI with DCE & DWI (unless contraindicated) after brachytherapy
3, 6, and 12 months
