ABSTRACT
PURPOSE: Many survivors of rectal cancer experience persistent bowel dysfunction. There are few evidence-based symptom management interventions to improve bowel control. The purpose of this study is to describe recruitment and pre-randomization baseline sociodemographic, health status, and clinical characteristics for SWOG S1820, a trial of the Altering Intake, Managing Symptoms in Rectal Cancer (AIMS-RC) intervention. METHODS: SWOG S1820 aimed to determine the preliminary efficacy, feasibility, and acceptability of AIMS-RC, a symptom management intervention for bowel health, comparing intervention to attention control. Survivors with a history of cancers of the rectosigmoid colon or rectum, within 6-24 months of primary treatment completion, with a post-surgical permanent ostomy or anastomosis, and over 18 years of age were enrolled. Outcomes included total bowel function, low anterior resection syndrome, quality of life, motivation for managing bowel health, self-efficacy for managing symptoms, positive and negative affect, and study feasibility and acceptability. RESULTS: The trial completed accrual over a 29-month period and enrolled 117 participants from 34 institutions across 17 states and one US Pacific territory. At baseline, most enrolled participants reported self-imposed diet adjustments after surgery, persistent dietary intolerances, and bowel discomfort post-treatment, with high levels of constipation and diarrhea (grades 1-4). CONCLUSIONS: SWOG S1820 was able to recruit, in a timely manner, a study cohort that is demographically representative of US survivors of rectal cancer. Baseline characteristics illustrate the connection between diet/eating and bowel symptoms post-treatment, with many participants reporting diet adjustments and persistent inability to be comfortable with dietary intake.

BACKGROUND: Survivors of rectal cancer experience persistent bowel dysfunction after treatments. Dietary interventions may be an effective approach for symptom management and posttreatment diet quality. SWOG S1820 was a pilot randomized trial of the Altering Intake, Managing Symptoms in Rectal Cancer (AIMS-RC) intervention for bowel dysfunction in survivors of rectal cancer. METHODS: Ninety-three posttreatment survivors were randomized to the AIMS-RC group (N = 47) or the Healthy Living Education attention control group (N = 46) after informed consent and completion of a prerandomization run-in. Outcome measures were completed at baseline and at 18 and 26 weeks postrandomization. The primary end point was total bowel function score, and exploratory end points included low anterior resection syndrome (LARS) score, quality of life, dietary quality, motivation, self-efficacy, and positive/negative affect. RESULTS: Most participants were White and college educated, with a mean age of 55.2 years and median time since surgery of 13.1 months. There were no statistically significant differences in total bowel function score by group, with the AIMS-RC group demonstrating statistically significant improvements in the exploratory end points of LARS (p = .01) and the frequency subscale of the bowel function index (p = .03). The AIMS-RC group reported significantly higher acceptability of the study. CONCLUSIONS: SWOG S1820 did not provide evidence of benefit from the AIMS-RC intervention relative to the attention control. Select secondary end points did demonstrate improvements. The study was highly feasible and acceptable for participants in the National Cancer Institute Community Oncology Research Program. Findings provide strong support for further refinement and effectiveness testing of the AIMS-RC intervention.

BACKGROUND AND OBJECTIVES: Following gastric and esophageal cancer surgery, patients often experience significant, prolonged eating-related symptoms. One promising approach to help patients improve their eating-related quality of life (QOL) is through self-management coaching to aid in diet modification. We performed a randomized pilot study of a nutritionist-led telehealth intervention for the self-management of eating after gastroesophageal cancer surgery. METHODS: Patients who were within 30 days of resuming oral intake after undergoing surgery for gastric and/or esophageal cancer were consented and then randomized to the intervention or usual care. The intervention was performed by a nutritionist trained in self-management coaching and delivered in four telehealth sessions over 4 months. The following outcomes were measured at baseline and at 6 months after baseline: QOL (EORTC QLQC30), weight, body mass index, and sarcopenia. RESULTS: Fifty-three patients were enrolled. 22/27 usual care and 21/26 intervention patients completed the study for a retention rate of 81%. Differences between the intervention and control groups were not statistically significant, but the intervention group had indications of greater improvements in overall QOL as measured by EORTC QLQC30 Summary Score (8.7 vs. 2.3, p = 0.17) as well as greater improvements in 4/5 functional domains (p > 0.3). The intervention group also had slightly more weight gain (6 kg vs. 3 kg, p = 0.3) and less sarcopenia (3/16 vs. 9/18, p = 0.07). CONCLUSIONS: This pilot study demonstrated the feasibility and acceptability of a telehealth intervention for self-management of eating symptoms after gastroesophageal cancer surgery. There were trends toward improved overall QOL in the intervention group. A larger study is needed to validate the results.
