Brief Summary

The RE-CARE project is designed to evaluate the effects of a 24-week, remotely supervised, combined high-intensity interval aerobic and resistance exercise training on physical health and quality of life in patients with breast cancer (BC) undergoing neoadjuvant chemotherapy (NACT). The study will enroll women aged 30-65 years with previously untreated, primary breast cancer, clinical stage IIA-IIB or IIIA-IIIC, who are scheduled to receive doxorubicin/cyclophosphamide-based NACT. Participants will be randomly allocated to either an experimental intervention group or a control group. At baseline, comprehensive assessments will be conducted to evaluate cardiorespiratory fitness, physical endurance, muscle strength, cognitive function, and health-related quality of life. The primary objective is to determine the impact of the remotely supervised combined aerobic and resistance exercise on incidence and severity of NACT-related adverse effects in patients with BC.

Outcome Measures

Primary Outcomes (3)

  • Change in cardiorespiratory functioning, assessed by incremental test according to the University of Northern Colorado Cancer Rehabilitation Institute (UNCCRI) Treadmill protocol

    The UNCCRI Treadmill Protocol includes twenty-one 1-minute stages, with systematic increments in treadmill speed and/or grade at each stage. Outcome measures will include maximal oxygen uptake (max ml/kg/min) and ventilatory variables such as minute ventilation (L/min) and respiratory exchange ratio (RER). Heart rate (beats/min) will be continuously monitored throughout each test using a heart rate monitor. Time to exhaustion, treadmill speed, and treadmill grade will be recorded at the point of test termination. Data obtained will be analyzed using repeated-measures analysis and linear mixed-effects models.

    From baseline to 6 months after the intervention

  • Change in Health-Related Quality of Life, assessed by European Organisation for Research and Treatment of Cancer Core Quality of Life questionnaire-Core 30 (EORTC QLQ-C30)

    Participants will be asked to complete the EORTC QLQ-C30, a 30-item questionnaire, electronically. This instrument includes a global health status/quality-of-life scale and multiple functional subscales (physical, emotional, cognitive, social, and role functioning). It further incorporates several symptom subscales assessing fatigue, nausea and vomiting, pain, dyspnea, insomnia, appetite loss, constipation, diarrhea, and financial difficulties. Patients respond to the items using Likert scale (1 = "Not at all," 2 = "A little," 3 = "Quite a bit," and 4 = "Very much"). All scales and single-item measures yield scores ranging from 0 to 100%. For the functional scales, higher scores indicate better functioning, but for the symptom scales, higher scores reflect greater symptom severity. Data obtained will be analyzed using repeated-measures analysis and linear mixed-effects models.

    From baseline to 6 months after the intervention

  • Change in Health-Related Quality of Life, assessed by European Organisation for Research and Treatment of Cancer Core Quality of Life questionnaire - Breast Specific module EORTC QLQ-BR23.

    In addition, participants will complete the EORTC QLQ-BR23, a 23-item, breast cancer-specific questionnaire that includes functional scales (body image, sexual functioning, sexual enjoyment, future perspective) and symptom scales (systemic therapy side effects, breast symptoms, arm symptoms). Patients respond to the items using Likert scale (1 = "Not at all," 2 = "A little," 3 = "Quite a bit," and 4 = "Very much"). All scales and single-item measures yield scores ranging from 0 to 100%. Data obtained will be analyzed using repeated-measures analysis and linear mixed-effects models.

    From baseline to 6 months after the intervention

Secondary Outcomes (11)

  • Change in body composition assessed by Body Height (m)

    From baseline to 6 months after the intervention

  • Change in body composition assessed by Body Weight (kg)

    From baseline to 6 months after the intervention

  • Change in body composition assessed by Body Mass Index (BMI)

    From baseline to 6 months after the intervention

  • Change in physical functioning, assessed by 6 Minute Walk tests (6MWT)

    From baseline to 6 months after the intervention

  • Change in lower limb strength, assessed by 30 second sit to stand (30STS)

    From baseline to 6 months after the intervention

  • +6 more secondary outcomes

Study Arms (2)

Control group

NO INTERVENTION

The control group will maintain their routine activities and usual care and will receive the American College of Sports Medicine (ACSM) guidelines (Campbell et al., 2019), but they will not be assigned any structured physical exercise program during the study period.

Intervention group

EXPERIMENTAL
Other: Intervention Group

Interventions

The intervention group will receive remotely supervised sessions conducted by health professionals approximately three times per week for 24 weeks, ensuring no more than 48 hours elapse between two sessions. Individually customized aerobic high intensity interval and resistance training sessions will be carried out on alternating days using a smartwatch, heart rate monitor (polar H10 sensor), resistance bands with real-time monitoring sensors (bandcizer sensor), and the linked smartphone applications (Resistance Band Tracker and Polar Flow).
