OvS Breast: Ovarian Suppression in Breast Cancer Interventions

Combined intervention evaluation on weight control

A combined intervention based on physical exercise, nutritional control, and individualized psycho-oncological support can achieve weight control and maintain adequate body composition in premenopausal women with localized breast cancer expressing estrogen receptors and progesterone receptors who receive adjuvant treatment. The psycho-oncological intervention program aims to increase motivation to adhere to the physical exercise program and nutritional recommendations and maintain long-term healthy lifestyle habits.

Combined intervention evaluation in body composition

The variables weight, kilograms, fat mass, lean mass, and extracellular water will be obtained with the Tanita BC-601 Gold scale, including an impedance meter. The height, waist, and hip circumferences will be obtained with a tape measure. These measurements are necessary for calculating the BMI and the waist-high index (measure in centimeters). Weight and height will be combined to report BMI in kg/m\^2 Units of measure: weight in kilograms, height in meters.

Improve Quality of Life on Patient Report Outcomes

To evaluate the impact of the combined intervention program on patient-reported outcomes (PROs) (exercise level , asthenia, self-perception, anxiety and depression). The combination of several validated tests allows us to establish a balanced measure with the multi-professional approaches that care for the patient. Patient Reported Outcomes (PROs): These will be assessed and collected by completing validated questionnaires for this purpose. * Quality of life: EuroQoL-5D questionnaire * Fatigue: FACIT-Fatigue questionnaire * Level of physical activity: International Physical Activity Questionnaire (IPAQ) * Self-perception/self-esteem: Rosemberg Self-Esteem Scale * Anxiety and Depression: Hospital Anxiety and Depression Scale (HADS)

Nutritional Status follow-up

Nutritional status: It will be assessed using the following tools at the beginning, 6 weeks after the start of the intervention and at the end of the 12 weeks.The combination of several validated tests allows us to establish a balanced measure of the specific situation in each patient. * 3-day nutritional record * Predimed Mediterranean diet adherence questionnaire * WCRF/AICR recommendations compliance scale

Psycho-oncological assessment

Psycho-oncological assessment: It will be assessed with the following questionnaires that the patient will complete at the beginning and the end of the 12 weeks of intervention. The combination of several validated tests allows us to establish a measure that relates the emotional state with the variables of physical exercise The PANAS affectivity scale will have an additional intermediate evaluation six weeks after the start of the intervention. * PANAS affectivity scale * Transtheoretical model of change in physical exercise (CMTCEJ) questionnaire. * MOS social support questionnaire

Cardiorespiratory Fitness: Evaluation of physical activity performance

Evaluation of physical activity performance thought: -Cardiorespiratory fitness (CRF): The Bruce test will be evaluated to determine the maximum oxygen consumption (VO2max, milliliters/kilogram/minute). -Cardiac variability (HR at rest and maximum (beats/minute)): It will be measured with an HR receiver before the Bruce test (at rest) and at the time of finishing it (maximum effort)
