• Conditions: Prognostic Stage IB Breast Cancer AJCC v8; Anatomic Stage IIIC Breast Cancer AJCC v8; Prognostic Stage I Breast Cancer AJCC v8; Prognostic Stage IA Breast Cancer AJCC v8; Prognostic Stage IIA Breast Cancer AJCC v8; Prognostic Stage IIB Breast Cancer AJCC v8; Prognostic Stage IIIA Breast Cancer AJCC v8; Anatomic Stage 0 Breast Cancer AJCC v8; Anatomic Stage I Breast Cancer AJCC v8; Anatomic Stage IIA Breast Cancer AJCC v8

• Registration Number: NCT04200482
• Lead Sponsor: Fred Hutchinson Cancer Center

Brief Summary

The purpose of this phase II trial is to identify the most effective dose level (number of classes) of a diet and physical activity lifestyle program based on how well it improves diet and physical activity in stage 0-III breast cancer survivors. Study results may provide researchers with information on how to best implement diet and physical activity recommendations among breast cancer survivors.

Detailed Description

OUTLINE: Participants are randomized to 1 of 2 arms.

ARM A (LOW DOSE): Participants attend one diet and physical activity class delivered remotely via Zoom and receive an eHealth communication intervention for 6 months.

ARM B (HIGH DOSE): Participants attend 12 twice monthly diet and physical activity online sessions delivered remotely via Zoom and receive an eHealth communication intervention for 6 months.

Primary Outcome Measures

Name	Time	Method
Accrual rate	At 6 months	Accrual rate will be measured by number of participants randomized during each month of study accrual.
Adherence: Responsiveness to eHealth communication	At 6 months	Adherence will be measured by the number of responses to text messages per participant.
Biospecimen collection rate	At 6 months	Biospecimen collection rate will be assessed based on number of biospecimens collected.
Retention	At 6 months	Retention will be measured by the number of completed study assessments per participants.
Acceptability: Questions during exit interview	At 6 months	Acceptability will be measured by questions asking about trial acceptability in the exit questionnaire.
Adherence: Session(s) Attendance	At 6 months	Adherence will be measured by number of online session(s) attended per participant.

Secondary Outcome Measures

Name	Time	Method
Change in daily servings of fruits and vegetables per day	Baseline to 6 months	Will be assessed by 24-hour dietary recalls.
Change in minutes per week of moderate-to-vigorous physical activity	Baseline to 6 months	Will be assessed by 7-day accelerometer data.
Change in systemic inflammation	Baseline to 6 months	Will be assessed by fasting blood concentrations of high sensitivity C-reactive protein.
Change in gut barrier permeability	Baseline to 6 months	Will be assessed by fasting circulating levels of gut bacterial endotoxin liposaccharide-binding protein.
