Tumour Cell Response to Acute Aerobic Exercise in Breast Cancer Survivors: Modulatory Effects of Exercise Type and Intensity

Summary

Cancer has emerged as a prominent cause of mortality in the 21st century, with breast cancer (BC) being the most diagnosed malignancy. Multidisciplinary cancer management has improved survival chances, but side effects and long-term consequences of treatments have significant implications for cancer survivors' health-related quality of life. Exercise is increasingly considered and used in cancer treatment and follow-up. However, studies demonstrating the biological mechanisms underlying the anticarcinogenic effects (ACE) of exercise are insufficient to justify the most appropriate physical activity for different clinical scenarios. Achieving scientific excellence in understanding the ACE of exercise in cancer management is critical to optimize treatment and enhance patients' quality of life.

Eligibility

Inclusion Criteria (intervention group):

* Reproductive age (premenopausal);
* Diagnosis of Stage II-III Triple-Negative Breast Cancer (TNBC) (negative for estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2));
* Timeframe of 3 to 9 months after completion of surgery, adjuvant chemotherapy, radiation therapy, and/or immunotherapy;
* Physician-certified (cardiologist) physical fitness for exercise testing, supported by echocardiography (ECHO).

Inclusion Criteria (control group):

* Reproductive age (premenopausal);
* No current or prior diagnosis of any type of cancer;
* Matched by age, body constitution, and physical fitness to the breast cancer participant group.

Exclusion Criteria:

* Pregnancy;
* Autoimmune diseases (e.g., thyroiditis, inflammatory bowel disease, atopic dermatitis, etc.);
* Endocrine disorders (e.g., metabolic syndrome, diabetes);
* Cardiovascular diseases;
* Diagnosis of any other type of oncological disease;
* Any condition for which physical activity is contraindicated (e.g., asthma, COPD, spinal disc herniation, severe iron deficiency anemia).
