Exercise Intervention in Targeting Adiposity and Inflammation With Movement to Improve Prognosis in Breast Cancer

21 ottobre 2019 aggiornato da: University of Southern California

Taking AIM at Breast Cancer: Targeting Adiposity and Inflammation With Movement to Improve Prognosis in Breast Cancer Survivors

This randomized phase II trial studies how well exercise intervention works in targeting adiposity and inflammation with movement to improve prognosis in stage I-III breast cancer survivors. Different types of exercise may reduce inflammation in fat tissue and minimize the risk of cancer recurrence related to being overweight or obese.

Panoramica dello studio

Descrizione dettagliata

PRIMARY OBJECTIVES:

I. To determine the effects of a 4-month circuit, interval-based aerobic and resistance exercise (CARE) intervention on obesity-associated chronic inflammation.

SECONDARY OBJECTIVES:

I. To determine the effects of a 4-month CARE intervention on sarcopenic obesity.

TERTIARY OBJECTIVES:

I. To determine the effects of a 4-month CARE intervention on breast cancer prognosis and assess whether reductions in chronic inflammation are associated with breast cancer prognosis.

OUTLINE: Patients are randomized to 1 of 3 groups.

GROUP I: Patients undergo supervised CARE program over 50 minutes comprising of warm up over 5 minutes, moderate to vigorous aerobic and resistance exercises over 40 minutes, and cool down over 5 minutes 3 days per week for 16 weeks.

GROUP II: Patients undergo supervised traditional aerobic and resistance exercise (TARE) program over 80 minutes comprising of warm up over 5 minutes, aerobic exercise over 15 minutes, resistance exercise over 55 minutes, and cool down over 5 minutes 3 days per week for 16 weeks.

GROUP III: Patients undergo home-based stretching program comprising of one set of 3-4 static stretching exercises held for 30 seconds 3 days per week for 16 weeks. Patients receive instructional digital video disc (DVD) and booklet of the flexibility exercises. Patients also complete a weekly activity log. After completion of the stretching program, patients may optionally undergo the CARE program as in group I.

After completion of study, patients are followed up at week 34, 8 and 12 months, and then every year for 8 years.

Cosa sta misurando lo studio?

Misure di risultato primarie

Misura del risultato
Misura Descrizione
Lasso di tempo
Reduction of adipose tissue inflammation assessed by measuring M1 and M2 adipose tissue macrophages, crown-like structures, and adipose tissue secretion levels of inflammatory cytokines secreted
Lasso di tempo: Up to 16 weeks
Analyses for each of the continuous outcomes will involve mixed effects linear regression models, to incorporate the repeatedly measured outcomes. Dependent variables will be the 2- and 4-month measurements of trial outcomes assessed during and at the end of the intervention period. Independent variables will include two indicator variables for treatment group (TARE, attention control) relative to CARE, the baseline value of the outcome, and an indicator variable for measurement time (2-month/4-month). The treatment group effect (2 degrees of freedom) will test for differences in TARE and/or attention control, relative to CARE on the 2- and 4-month outcomes.
Up to 16 weeks

Misure di risultato secondarie

Recurrence-free interval defined as events directly attributable to the original breast cancer including invasive ipsilateral breast tumor recurrence; local, regional or distant recurrence; and death from breast cancer
Lasso di tempo: Up to 8 years
A competing risks analysis will be conducted, with death modeled as a competing event, using the Fine-Gray proportional hazards model. Analyses will be presented unadjusted, as well as adjusted for prognostic variables (age, estrogen receptor (ER)/HER2 status, tumor size, presence/number of positive nodes, and surgery (mastectomy vs. breast-sparing).
Up to 8 years
Sarcopenic obesity assessed using dual energy X-ray absorptiometry
Lasso di tempo: Up to 8 months
Analyses for each of the continuous outcomes will involve mixed effects linear regression models, to incorporate the repeatedly measured outcomes. Dependent variables will be the 2- and 4-month measurements of trial outcomes assessed during and at the end of the intervention period. Independent variables will include two indicator variables for treatment group (TARE, attention control) relative to CARE, the baseline value of the outcome, and an indicator variable for measurement time (2-month/4-month).

Lasso di tempo
Disease free survival (DFS)
Lasso di tempo: From randomization to documentation of disease recurrence or death from any cause, assessed up to 8 years
Kaplan-Meier estimates and log-rank tests will be used to estimate and initially test cumulative survival probabilities by treatment group. Cox proportional hazards models will be used to compare treatment groups (with 2 indicator variables for treatment group). Ancillary analyses will assess associations of inflammation measures with DFS. Results will be presented as hazard ratios, with 95% confidence intervals.
