Effects of Moderate-intensity Interval Aerobic Exercise (MIIAE) on Inflammatory, Immune, Metabolic, Physical Fitness, and Quality of Life Parameters in Breast Cancer Patients Undergoing Radiotherapy.

2026년 5월 6일 업데이트: Universidad Francisco de Vitoria

Breast cancer and its treatment with radiotherapy may be associated with systemic inflammatory, hematological, cardiac, body composition, functional and quality-of-life alterations. Exercise has emerged as a non-pharmacological strategy with potential benefits during oncological treatment; however, further evidence is needed regarding the effects of supervised moderate-intensity interval aerobic exercise during radiotherapy.

This randomized controlled trial aims to evaluate the effects of a supervised moderate-intensity interval aerobic exercise programme on systemic inflammatory and immune-derived hematological indices, cardiac biomarkers, body composition, muscle strength, lower-limb power, sleep quality and breast cancer-specific quality of life in women with breast cancer undergoing radiotherapy.

Participants will be allocated to either an experimental group performing supervised moderate-intensity interval aerobic exercise during radiotherapy or to a control group receiving usual care without structured exercise during the study period. Outcomes will be assessed at baseline and after completion of the intervention period.

실험적: Moderate-Intensity Interval Aerobic Exercise
Participants perform a supervised moderate-intensity interval aerobic exercise programme during the radiotherapy treatment period. Training is conducted 3 days per week, on alternate days, under the supervision of a physiotherapist experienced in therapeutic exercise in oncology. Exercise intensity is prescribed individually according to baseline physiological testing, including lactate response, perceived exertion and clinical tolerance. Participants continue receiving standard oncological care during radiotherapy.
다른: Moderate-Intensity Interval Aerobic Exercise
Structured and supervised aerobic exercise intervention based on moderate-intensity interval training. The programme includes repeated aerobic exercise bouts interspersed with recovery periods. Exercise intensity is individually prescribed and adjusted according to baseline physiological assessment, including blood lactate response, perceived exertion and clinical tolerance. The intervention is delivered during the radiotherapy treatment period as an adjunct to standard oncological care.
간섭 없음: Usual Care During Radiotherapy
Participants allocated to the control group receive standard oncological care during the radiotherapy treatment period and do not participate in a structured exercise programme during the study period. Participants are instructed to maintain their usual lifestyle throughout radiotherapy. After completion of the study, participants in the control group are offered the same supervised moderate-intensity interval aerobic exercise programme delivered to the experimental group.

주요 결과 측정

결과 측정
측정값 설명
기간
Systemic Immune-Inflammation Index (SII)
기간: Baseline (pre-intervention) and immediately after intervention
Systemic Immune-Inflammation Index (SII) will be calculated from peripheral blood parameters obtained through standard hematological analysis using an automated analyzer. The index will be computed using the formula: platelet count × neutrophil count / lymphocyte count. Blood samples will be collected under standardized conditions after an overnight fast, with participants instructed to avoid vasoactive medication, caffeine, alcohol and tobacco prior to sampling. Post-intervention samples will be obtained at least 48 hours after the last exercise session to ensure assessment of chronic rather than acute responses. This composite index will be used to quantify changes in systemic inflammatory and immune status associated with the intervention.
Baseline (pre-intervention) and immediately after intervention
Neutrophil-to-Lymphocyte Ratio (NLR)
기간: Baseline (pre-intervention) and immediately after intervention
Neutrophil-to-Lymphocyte Ratio (NLR) will be calculated from absolute neutrophil and lymphocyte counts obtained through peripheral blood analysis using an automated hematology analyzer. This index will be used as a marker of systemic inflammatory balance.
Baseline (pre-intervention) and immediately after intervention
Platelet Count
기간: Baseline (pre-intervention) and immediately after intervention
Platelet count will be obtained from peripheral blood samples using standard hematological procedures and automated analysis, and will be used as a parameter of systemic inflammatory and hematological status.
Baseline (pre-intervention) and immediately after intervention
Neutrophil Count
기간: Baseline (pre-intervention) and immediately after intervention
Absolute neutrophil count will be obtained from peripheral blood analysis using an automated hematology analyzer and will be used to assess innate immune response.
Baseline (pre-intervention) and immediately after intervention

Relative Lower-Limb Power: Handgrip Strength
기간: Baseline (pre-intervention) and immediately after intervention
Right and left handgrip strength will be measured (kg) using a calibrated handheld dynamometer.

The highest reproducible value for each hand will be recorded.
Baseline (pre-intervention) and immediately after intervention
Relative Lower-Limb Power (Chair Stand Test)
기간: Baseline (pre-intervention) and immediately after intervention
Relative lower-limb power will be assessed using the 30-second Chair Stand Test. Participants will perform as many full stands as possible from a standardized chair (≈43-45 cm height) within 30 seconds, with arms crossed over the chest. The number of repetitions will be recorded. A relative lower-limb power index will be derived from repetitions and body mass, expressed in W/kg equivalent units, providing an estimate of lower-limb functional performance normalized by body mass.
Baseline (pre-intervention) and immediately after intervention
Breast Cancer-Specific Functional Quality of Life
기간: Baseline (pre-intervention) and immediately after intervention
Functional quality of life will be assessed using the functional scales of the EORTC QLQ-C30 and QLQ-BR45 questionnaires. Scores will be linearly transformed to a 0-100 scale, where higher scores indicate better functional status.
