Feasibility trial of STRONG: A digital intervention to improve nutritional management for individuals with esophageal and gastroesophageal junction cancer.

INTRODUCTION

Individuals with esophageal and gastroesophageal junction (GEJ) cancers are at especially high risk of malnutrition. However, most patients with malnutrition do not receive adequate nutritional support. We conducted a single-arm trial to test the implementation of Support Through Remote Observation and Nutrition Guidance (STRONG), a multilevel digital intervention to improve nutritional outcomes for patients with locally advanced esophageal and gastroesophageal junction cancer.

METHODS

Participants received five nutritional counseling sessions with a dietitian, logged daily food intake through the Fitbit app, and completed five study assessments related to patient malnutrition, nutrition-related symptoms, and quality-of-life outcomes. We assessed the feasibility, acceptability, and usability of STRONG against a priori benchmarks.

RESULTS

Participants (N = 17) had a median age of 68 years, and 71 % were male. Feasibility benchmarks were met for participants completing the baseline assessment (94 %), completing four out of five assessments (82 %), and participant retention (85 %). Among participants who only received an oral diet during the study period, adherence to dietetic appointments (89 %) and food intake tracking (78 %) were high. Participant recruitment rate (47 %) was slightly below the benchmark (50 %). All participants found the intervention to be acceptable. Usability of the intervention was high, with 69 % and 92 % of participants reporting high satisfaction with tracking food intake through the Fitbit and the dietitian-led nutrition counseling sessions, respectively.

CONCLUSION

Our study demonstrated that STRONG could be implemented with high feasibility, acceptability, and usability for esophageal and GEJ cancer patients. Findings from this study can guide a future efficacy study to assess the impact of STRONG on patient outcomes.

CLINICAL TRIAL REGISTRATION: The Support Through Remote Observation and Nutrition Guidance Program for Gastroesophageal Cancer Patients (STRONG-GEC) study was registered on clinicaltrials.gov (NCT05438940) in June 2022 prior to participant enrollment.
