Programa de reducción del estrés basado en mindfulness para la disminución del dolor en el cáncer de mama.

Abstract

This study aimed to analyze the efficacy of the Mindfulness-Based Stress Reduction (MBSR) program in reducing pain in women with breast cancer. Pain is a common symptom in this population and significantly impacts their quality of life. This research employed a systematic review using both qualitative and quantitative approaches, focusing exclusively on randomized clinical trials published between 2014 and 2024. The CONSORT statement and the RoB 2.0 tool were used to assess reporting quality and risk of bias, respectively. The search was conducted in PubMed, Scopus, and ProQuest, yielding 11 articles. These studies showed a reduction in physical pain within the intervention group; however, this reduction was not statistically significant compared to the control group. Furthermore, it had a small Cohen's d effect (d = 0.17). In line with this, a high risk of bias was identified through the RoB 2.0 tool in most documents and moderate reporting quality could be determined through CONSORT. In conclusion, the included trials did not demonstrate a statistically or clinically relevant difference in pain perception between groups, and the effect size was small. These findings highlight the need to explore other complementary interventions for pain management in this population.
