# Baseline characteristics and recruitment for SWOG S1820: altering intake, managing bowel symptoms in survivors of rectal cancer (AIMS-RC)

## TL;DR

This study reports on the recruitment and baseline characteristics of a trial testing a dietary intervention to manage bowel symptoms in rectal cancer survivors.

## Contribution

The study provides baseline data and recruitment insights for a novel dietary symptom management intervention in rectal cancer survivors.

## Key findings

- The trial enrolled 117 participants from 34 institutions across 17 states and a US Pacific territory.
- Baseline data showed persistent bowel dysfunction and diet adjustments among participants.
- Recruitment was timely and the cohort was demographically representative of US rectal cancer survivors.

## Abstract

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.

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.

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).

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.
