ABSTRACT
OBJECTIVES: Non-Cyclical mastalgia (NCM) is a chronic breast pain condition in women of reproductive age, often linked to anxiety and reduced quality of life (QoL). Evidence suggests central sensitization (CS) may contribute to NCM, but its clinical significance and management remain unclear.
METHODS: This cross-sectional study included 201 women aged 25 to 65, with 106 NCM patients and 95 healthy controls, to investigate the association between NCM and central sensitization syndromes (CSS). Data collection involved demographic characteristics and assessments using the Central Sensitization Inventory (CSI), Nottingham Health Profile (NHP), Short-Form McGill Pain Questionnaire (SF-MPQ), Pain Detect, Leeds Assessment of Neuropathic Symptoms and Signs (LANSS), and Hospital Anxiety and Depression Scale (HADS). The main outcome is to reveal the interrelationship between NCM and CSS.
RESULTS: NCM patients had significantly higher Central Sensitization Inventory-A (CSI-A) scores than controls (p < 0.001), with 15.1% surpassing the critical threshold of 40, indicating pronounced CS. NCM patients also had increased NHP-1, NHP-2, and HADS-total scores (p = 0.008, p = 0.003, p = 0.004), reflecting greater distress. Subgroup analyses showed more intense pain (p < 0.001) and sleep disturbances (p = 0.002). CSI-A scores strongly correlated with SF-MPQ, LANSS, Pain Detect, and HADS (all p < 0.001). Regression analysis identified pain duration, Pain Detect, and SF-MPQ sensory scores as key predictors of CSI-A (p < 0.001).
DISCUSSION: NCM shares characteristics with chronic pain syndromes linked to CSS. Multidisciplinary approaches and innovative treatments, such as cognitive therapies combined with integrative approaches may improve outcomes.
