Summary

In this randomized, controlled, prospective, two-arm intervention study, the investigators plan to investigate the effects of high-intensity interval training in women diagnosed with triple-negative breast cancer. Breast cancer is one of the most common cancers and one of the leading causes of cancer-related deaths worldwide. Among the different subtypes, triple-negative breast cancer accounts for about 15-20% of all breast cancer cases and is characterized by a more aggressive clinical course. Recent results indicate that the percentage of patients with a pathologic complete response was 13% higher in the chemotherapy-immunotherapy group (by 64.8%) than in the placebo-chemotherapy group (51.2). High-intensity interval training has a positive effect on the immune system, suggesting that it may improve the efficacy of chemo-immunotherapy, leading to a higher rate of pathologic complete response (pCR) in patients with newly diagnosed triple-negative breast cancer. In addition to the immunomodulatory effects, this exercise model could boost microvascular perfusion, thereby improving tumor perfusion, enhancing chemo-immunotherapy and leading to better outcomes.

Detailed description

Recent clinical trials showed promising results in patients with triple negative breast cancer (TNBC) who received four cycles of pembrolizumab (at a dose of 200 mg) every three weeks + standard chemotherapy, compared to patients who received placebo + chemotherapy alone. Importantly, the overall risk of disease progression that precluded surgery, local or distant recurrence, occurrence of a second primary cancer, or death from any cause was 37% lower with pembrolizumab chemotherapy compared to placebo chemotherapy. Exercise training is a supportive multi-effect strategy with the ability to influence multiple organ systems. There is growing epidemiologic evidence that a physically active lifestyle is associated with a lower risk of developing cancer, particularly colon and breast cancer. Recent preclinical studies suggest that exercise can control and attenuate the growth of tumor cells. Therefore, exercise could be a potential means to increase the rate of pCR in cancer patients in general. High-intensity interval training resulted in higher cardiorespiratory fitness levels, particularly in breast cancer and lung patients who exercised for at least 8 weeks, with a significant improvement (from 2.40 to 4.19 mL-min-1-kg-1) observed compared to control groups. The aim of this study is to investigate the effects of HIIT training on immune system response and pCR rates (most commonly defined as complete eradication of the tumor as a surrogate parameter for good prognosis) during neoadjuvant immunochemotherapy in women with TNBC. The working hypothesis is that HIIT training would activate the immune system and enhance the combination of neoadjuvant treatment, leading to higher rates of pCR in the aerobic group compared to the usual treatment group. Thus, this exercise model may also promote microvascular perfusion, improve tumor perfusion, and potentially lead to more favorable outcomes in neoadjuvant therapy, increasing the efficacy of systemic treatments and allowing for better therapeutic outcomes. The researchers support the idea that high-intensity aerobic exercise may at least partially challenge the large heterogeneity in response to medical treatment in women with a first diagnosis of TNBC and lead to higher response rates in the experimental group.

Interventions

Type	Name	Description
OTHER	Exercise intervention - High intensity interval training on a cycle-ergometer	The experimental group starts with 5 minutes of unloaded cycling, followed by 3 × 3-minute HIIT training sequences alternating between: i) 30 seconds at 90% of maximal PO (70 rpm for 30 seconds) and ii) 30 seconds of light pedaling at 20% of PO). Recent work suggests that this high-intensity approach to aerobic exercise is feasible and safe, even during acute oncology treatment. The HIIT sequences are interspersed with two 3-minute cycling sessions at moderate intensity. The training session will be concluded with a 5-minute cool-down by cycling (light pedaling) and stretching. This protocol will be performed twice a week throughout the study, and all patients who reach an 80% adherence threshold for the exercise intervention will be included in the final analysis.
