Dolor crónico tras la cirugía de mama: incidencia, factores de riesgo e impacto en la calidad de vida

Introduction and objectives

Breast cancer is the most frequently diagnosed malignancy, and chronic pain after breast surgery (CPBS) is an increasingly recognized therapy-related problem. We evaluated CPBS incidence, characteristics, associated factors, and impact on patient quality of life (QoL).

Materials and methods

Six-month observational prospective study in patients undergoing breast surgery in a tertiary university hospital. Data were collected using several questionnaires: Pain Catastrophizing Scale, Brief Pain Inventory-Short Form, Douleur Neuropathique 4 Questionnaire, and European Organization for Research and Treatment of Cancer Quality of Life Questionnaire and its Breast Cancer Module.

Results

A total of 112 patients completed the study. Approximately, one third (34.8%) developed CPBS, almost all with potentially neuropathic pain. CPBS interfered with patients’ daily life and reduced their QoL. Diabetes (p=.028), catastrophizing (p=.042), and acute postoperative pain severity (p<.001) were associated with CPBS.

Conclusions

This study broadens our understanding of CPBS and shows the impact of this syndrome. Healthcare workers need to be aware of CPBS and take steps to prevent and treat it, and provide patients with adequate information.
