What is the purpose of this trial?

This trial explores how exercise affects inflammation and blood vessel health in women undergoing breast cancer treatment. Researchers aim to determine if regular exercise during chemotherapy reduces unwanted effects on small blood vessels. Participants will either follow a structured exercise program or join a control group without the exercise plan. This trial suits women diagnosed with non-metastatic breast cancer who are currently receiving specific chemotherapy treatments and can safely engage in moderate exercise. As an unphased trial, it offers a unique opportunity to contribute to understanding the broader benefits of exercise during cancer treatment.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. Please consult with the trial coordinators or your doctor for guidance.

What prior data suggests that this exercise intervention is safe for breast cancer patients?

Research shows that exercise programs like "Taking Charge during Treatment" (TCT) are generally safe for breast cancer survivors. Studies have found that regular physical activity can lower inflammation and improve heart health. In past research, participants have completed exercise plans similar to TCT without major problems.

Similar exercise studies have reported no serious side effects, suggesting that the TCT program is likely safe for participants. This indicates that the TCT program, which promotes moderate to vigorous exercise, could be a safe choice for those undergoing cancer treatment. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about the "Taking Charge during Treatment" (TCT) intervention because it focuses on empowering breast cancer patients to actively manage inflammation through exercise, which is different from traditional treatments that often rely on medication alone. Unlike standard therapies, TCT integrates the American College of Sports Medicine's exercise guidelines, encouraging participants to engage in regular moderate to vigorous physical activity and resistance training during and after chemotherapy. This approach not only promotes physical fitness but also aims to improve overall well-being, potentially reducing inflammation in a natural, non-pharmacological way. By incorporating tools like activity trackers and personalized text messaging support, TCT ensures participants stay motivated and engaged throughout their treatment journey.

What evidence suggests that the Taking Charge during Treatment (TCT) Intervention could be effective for breast cancer-related inflammation?

Research has shown that exercise can help lower inflammation, which is important for people with breast cancer. In this trial, participants may be assigned to the Taking Charge during Treatment (TCT) Intervention. Studies have found that this intervention can improve heart health by reducing inflammation and possibly lowering the risk of major heart issues. Following the TCT's guidelines of regular moderate to vigorous exercise and resistance training can also boost overall health and quality of life for cancer survivors. Evidence suggests that staying active during cancer treatment can help manage inflammation and improve the outlook for breast cancer patients. ^{2 6 7 8 9}

What Are the Treatments Tested in This Trial?

Interventions

• Taking Charge during Treatment (TCT) Intervention

Trial Overview The study tests the 'Taking Charge during Treatment' (TCT) Intervention aimed at understanding how cancer treatment-induced inflammation affects blood vessel function and if exercise can mitigate these effects. It uses advanced -omics technologies to predict microvascular dysfunction from chemotherapy.

How Is the Trial Designed?

Group I: Taking Charge during Treatment (TCT) Intervention Active Control 1 Intervention

Taking Charge during Treatment (TCT) Intervention. TCT is a 16-20week intervention that promotes adoption of the ACSM exercise guidelines for cancer survivors during treatment, including regular moderate to vigorous physical activity (150 minutes per week of moderate activity or 75 minutes per week of vigorous activity) and a minimum of twice weekly resistance training (RT) minutes during CTx and after. Participants will receive "Take Charge" program binder, 2-4 x weekly text messaging, activity tracker and resistance bands.

Group II: Control Group Active Control 1 Intervention

To ensure scientific rigor allowing us to test causal pathways associated with exercise, women will be randomized to the TCT intervention or control group arm. The control group will not receive the TCT intervention The investigators experience teaches us that to increase the likelihood of retaining control group participants, the investigators must offer some resources. Thus, the investigators will provide the control group with a one-page summary of the American College of Sports Medicine exercise recommendations, and the "Take Charge" program binder at the completion of the study. Participants will also receive resistance bands and activity tracker at the end of the study. 95 The investigators will also send weekly text messages with supportive content not related to exercise or lifestyle (i.e., a riddle, "take a moment to smile today," a picture of a baby animal).

Published Research Related to This Trial

A 12-week study involving 40 breast cancer survivors showed that high-intensity interval training (HIIT) led to greater reductions in body mass, fat mass, and inflammatory markers (like TNF-α and IL-6) compared to moderate-intensity continuous training (MICT).

HIIT also significantly improved physical fitness, as indicated by increases in VO2peak and lower body strength, suggesting it may be a more effective exercise therapy for managing chronic inflammation and improving health outcomes in breast cancer survivors.

In a pilot trial involving 10 breast cancer patients undergoing neoadjuvant chemotherapy, adding a supervised exercise program resulted in a significant decrease in body mass index (BMI) compared to those receiving chemotherapy alone (28.0 vs. 35.8, P = 0.03).

While the exercise group showed a trend towards lower Ki-67 levels (7% vs. 29%, P = 0.14), indicating potential benefits in tumor proliferation rates, the difference was not statistically significant, suggesting further research is needed to confirm these findings.

In a study involving 394 cancer patients, both high-intensity (HI) and low-to-moderate intensity (LMI) exercise did not show significant differences in inflammatory markers, indicating that exercise intensity may not impact inflammation levels during cancer treatment.

However, in a subgroup of 154 breast cancer patients undergoing chemotherapy, HI exercise led to a smaller increase in C-reactive protein (CRP) and tumor-necrosis factor alpha (TNFA) immediately after treatment compared to LMI, suggesting that HI exercise may help mitigate chemotherapy-related inflammation.

A 16-week exercise intervention involving resistance and high-intensity interval training (RT-HIIT) significantly reduced inflammation markers (IL-6 and CD8a) in breast cancer patients undergoing chemotherapy, which correlated with lower levels of fatigue.

The study found that changes in these inflammation markers mediated the exercise's beneficial effects on fatigue, suggesting that exercise can be an effective strategy to combat chemotherapy-induced fatigue by reducing inflammation.

A meta-analysis of eight high-quality trials involving 478 breast cancer survivors found that exercise significantly reduced inflammatory markers such as IL6, TNFα, and IL8, suggesting a positive effect on the tumor microenvironment.

The results support the idea that exercise can help modulate chronic low-grade inflammation in breast cancer survivors, reinforcing the importance of exercise as part of their treatment and recovery plan.

In a study involving 11 breast cancer survivors, 16 weeks of combined aerobic and resistance exercise training significantly reduced the production of pro-inflammatory cytokines IL-1ß and IL-6 in monocytes, suggesting an anti-inflammatory effect of exercise.

Acute exercise led to a temporary decrease in the expression of toll-like receptors (TLR2 and TLR4) on monocytes, indicating a potential immediate response to exercise, although this effect was not sustained with ongoing training.

An 8-week combined aerobic and strength exercise program for 16 female breast cancer survivors did not significantly alter the levels of key cytokines related to breast cancer, such as IL6 and IL8, indicating limited impact on inflammation or immune response.

However, the exercise intervention did stabilize CTACK levels in the exercise group, while levels increased in the control group, suggesting a potential benefit of exercise in maintaining certain cytokine levels post-treatment.

In a study of 75 postmenopausal breast cancer survivors, exercise did not significantly change levels of inflammatory markers IL-6, CRP, and TNF-α compared to usual care, suggesting that the relationship between physical activity and breast cancer survival may not be directly linked to inflammation.

However, women who achieved 80% of their exercise goals showed a significant reduction in IL-6 levels, indicating that meeting exercise targets may have beneficial effects on inflammation in this population.
