Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study evaluates the link between muscle health and immune health in breast cancer survivors. Regular exercise is known to improve overall survival in cancer patients but the mechanism is not known. In this study the investigators will evaluate if improving muscle mass and strength via exercise improves the immune system's ability to fight cancer.

This is a one armed study where in 30 breast cancer survivors will be recruited to a 4 month exercise intervention. Increase in muscle mass and strength will be correlated with immune cell frequency and function.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Breast cancer survivors with stronger and larger muscles have better overall survival and lower recurrence than women with weaker and smaller muscles. However, the mechanism for this association is currently unknown. A recent study from the investigators has shown that there is an association between the frequency of immune cell types that kill cancer and higher muscle mass and strength, with higher muscle mass and strength correlating with a higher frequency of cancer killing, effector memory, T cells. The investigators thus propose that increasing muscle mass and strength can improve overall survival and reduce recurrence by increasing the number of cancer killing immune T cells.

To test this hypothesis, the investigators will recruit 30 breast cancer survivors to an exercise program designed to increase their muscle mass and strength. The program will be optimized to each participant's level of fitness and strength and will be designed by experts in the field. Personal trainers will teach the participants how to exercise and use muscle resistance training equipment using the correct technique and will monitor progress to avoid injuries and to maximize training benefits.

The investigators will collect blood (to study immune cell subsets) and measure muscle strength and body composition (to measure muscle mass) for participants before and after the study.

The duration of the exercise training protocol is 4 months and participants will be asked to exercise 4 days a week; 2 days at the gym and 2 days at home.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Exercise

Four months of muscle resistance training (exercise) designed to increase muscle mass and strength. The exercise protocol includes four different lifts with weights including, squats, bench press, dead lift and overhead press. The weights for each lift will be optimized for each participant and increased as the participant adapts to the exercise routine.

Group Type EXPERIMENTAL

Exercise Intervention

Intervention Type OTHER

Participants will exercise under the supervision of expert personal trainers and follow an optimized exercise program tailored to the strength and fitness level of each participant. Participants will exercise for 16 weeks; 2 days a week at the gym for an hour and 2 days of the week at home for 45 minutes.
