Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Introduction: The significant improvement in breast cancer survival, largely attributable to biomedical and technological progress, makes it increasingly necessary to investigate the secondary effects linked to this pathology. Among these, cancer-related cognitive impairment (CRCI) stands out as one of the most frequent yet frequently overlooked complications.

Objective: To evaluate the impact of a structured cognitive training program on the management of CRCI in patients with breast cancer receiving active treatment.

Methodology: A randomized controlled clinical trial will be conducted with two arms: an Intervention Group (IG) and a Control Group (CG). The study will include patients with a recent diagnosis of breast cancer. Based on sample size calculations, 50 participants will be recruited-25 per group-to detect a minimum difference of 2.95 points on the MoCA (Montreal Cognitive Assessment), a tool commonly used to assess cognitive performance. All participants will receive an informational leaflet aligned with the latest WHO recommendations for preventing cognitive decline. In addition, the IG will complete an individualized cognitive training (CT) program focused on everyday cognitive skills (EC). The program will provide a dossier with 80 training sessions, structured into four phases (P1-P4) of 20 activities each, to be implemented monthly. Baseline assessments and a follow-up four months after the intervention will be carried out in both groups. Variables collected will include sociodemographic and clinical data, as well as outcome measures for cognitive status (MoCA), everyday cognition (PECC), anxiety levels (Hamilton scale), functional capacity (LB), sleep quality (PSQI), quality of life (ECOG), and subjective memory complaints (FACT-COG).

Impact: Findings from this study could support the development of targeted cognitive rehabilitation strategies and the implementation of clinical protocols for individuals undergoing breast cancer treatment. By addressing CRCI-an underrecognized but increasingly prevalent issue given rising survival rates-these interventions may contribute to improving patients' overall quality of life.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Group intervention

The program is organized into four progressive months: (1) cognitive and emotional security, with activities focused on attention, basic memory, and group bonding; (2) flexibility and problem solving, where executive functions, language, and personal narrative are stimulated; (3) cognitive challenges and emotional control, which strengthen spatial memory, self-concept, and relaxation techniques; and (4) closure and consolidation of learning, dedicated to reinforcing achievements, promoting gratitude, and strengthening mutual support. In this way, ALMA not only seeks to train the mind, but also to provide a space for comprehensive support for the emotional and physical well-being of the participants.

Group Type EXPERIMENTAL

Health Education Program

Intervention Type BEHAVIORAL

An informative leaflet will promote a healthy lifestyle with WHO guidelines to reduce cognitive decline, recommending a balanced diet, physical activity, social engagement, cognitive games, good sleep, stress management, hydration, and avoiding smoking and excessive alcohol.

Individual intervention group

The indiviudal cognitive training program (CT) focused on everyday cognition (EC) will be conducted individually. Each participant will receive a dossier specifically designed for the study.

The intervention will consist of four training periods over a duration of 4 months (Period 1, P1; Period 2, P2; Period 3, P3; Period 4, P4), with 20 activities each. Each period will last one month (5 activities per week).

Group Type EXPERIMENTAL

Group training program

Intervention Type BEHAVIORAL

The group cognitive training program (CT) on everyday cognition (EC) will be individualized, with each participant receiving a tailored dossier. The intervention includes four 1-month training periods (P1-P4), each featuring 20 activities, conducted at a rate of 5 activities per week over 4 months.

Health Education Program

Instructions and recommendations will be provided in an informative leaflet to promote an active and healthy lifestyle, encouraging self-care and good practices. This leaflet will include the new WHO guidelines, which recommend specific measures to reduce the risk of cognitive decline. These measures are: Eating healthy foods, engaging in physical activity, maintaining social connections, playing challenging cognitive games, getting good sleep, managing stress, staying hydrated, and avoiding smoking and excessive alcohol consumption.
