Testing Diet Intervention versus Non-Diet Intervention for Management of Bowel Symptoms in Rectal Cancer Survivors
- PRIOR TO STEP 1 REGISTRATION:
- Patients must have prior history of rectosigmoid colon cancer or rectal cancer, or sigmoid colon cancer. For patients with sigmoid colon cancer, there must be documentation of either partial proctectomy and/or anastomosis to the rectum
- Patients must have a post-surgical permanent ostomy or anastomosis
- Patient’s last date of treatment for rectal cancer (any surgery, chemotherapy, radiation therapy) must be at least 6 months prior to registration and not more than 24 months prior to registration
- Anastomosis patients must have low anterior resection syndrome (LARS) score of 21-42 (minor to major symptoms) within 7 calendar days prior to registration
- Patient must have completed all baseline questionnaires within 7 days prior to registration
- The S1820 Patient Contact form must be completed prior to patient registration
- Patients must be able to read, write and speak English. Study materials and telephone calls are only available in English
- Patients with a prior malignancy or concurrent malignancy that is currently not being treated, whose natural history or treatment (in the opinion of the treating physician) does not have the potential to interfere with the safety or efficacy assessment of the investigational regimen are eligible for this trial
- Patients who are currently undergoing treatment for another cancer will have a different symptom profile than what this study is targeting and are not eligible
- Patients who have been diagnosed with inflammatory bowel disease (IBD), such as ulcerative colitis or Crohn’s disease, are not eligible
- PRIOR TO STEP 2 REGISTRATION:
- Patient must meet all eligibility criteria for step 1
- Patient must have successfully completed (“pass”) the run-in period, as per email notification from the University of Arizona
- Patient must be registered to step 2 no more than 40 days after step 1 registration. If day 40 falls on a weekend or holiday, the limit may be extended to the next working day
- Patients must be informed of the investigational nature of this study and must sign and give written informed consent in accordance with institutional and federal guidelines
- As a part of the Oncology Patient Enrollment Network (OPEN) registration process the treating institution's identity is provided in order to ensure that the current (within 365 days) date of institutional review board approval for this study has been entered in the system

I. To compare total bowel function score, as measured by the Memorial Sloan-Kettering Cancer Center Bowel Function Instrument (BFI), at 18 weeks post-randomization between the intervention and attention control arms.
I. To compare total bowel function score at 26 weeks post-randomization between the intervention and attention control arms.
II. To compare bowel function subscale scores (dietary, urgency, frequency), as measured by the BFI at both 18- and 26- weeks post-randomization between the intervention and attention control arms.
III. To compare lower anterior resection syndrome (LARS) scores (for anastomosis participants only), quality of life, and dietary quality at both 18- and 26- weeks post-randomization between the intervention and attention control arms.
IV. To compare motivation, self-efficacy, and positive/negative affect at both 18- and 26- weeks post-randomization between the intervention and attention control arms.
V. To assess study feasibility, adherence, retention, and acceptability at both 18 and 26 weeks post-randomization.
VI. To explore variation in primary and exploratory study outcomes according to sex, and to investigate whether intervention effects on the primary outcome differ across subgroups defined by sex.
OUTLINE: Patients are randomized to 1 of 2 arms.
ARM I: Patients receive diet modification coaching via telephone for 10 sessions over 15-60 minutes over 17 weeks. Patients also receive 3 motivational messages per week via email and/or text message beginning after session 6.
ARM II: Patients receive general healthy living education via telephone for 10 sessions over 15-60 minutes over 17 weeks. Patients also receive 3 motivational messages per week via email and/or text message beginning after session 6.
After completion of study, patients are followed up at 26 weeks.
