Non-Cyclical Mastalgia as a Central Sensitization Component: Implications for Multidisciplinary Treatment Approaches

Area of Science:

• Pain research
• Women's health
• Central sensitization syndromes

Background:

• Non-cyclical mastalgia (NCM) is a chronic breast pain condition affecting women of reproductive age.
• NCM is associated with anxiety and reduced quality of life (QoL).
• Central sensitization (CS) is hypothesized to contribute to NCM, but its role is not fully understood.

Purpose of the Study:

• To investigate the association between NCM and central sensitization syndromes (CSS).
• To determine the clinical significance of CS in NCM patients.
• To explore potential management strategies for NCM.

Main Methods:

• Cross-sectional study of 201 women (106 NCM patients, 95 controls).
• Data collected: demographics, 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), Hospital Anxiety and Depression Scale (HADS).
• Main outcome: interrelationship between NCM and CSS.

Main Results:

• NCM patients exhibited significantly higher CSI-A scores than controls (p < 0.001).
• 15.1% of NCM patients exceeded the CS threshold (CSI-A > 40).
• NCM patients reported greater distress (higher NHP and HADS scores), pain, and sleep disturbances.
• CSI-A scores strongly correlated with pain measures (SF-MPQ, LANSS, Pain Detect) and HADS (all p < 0.001).
• Pain duration, Pain Detect, and SF-MPQ sensory scores predicted CSI-A (p < 0.001).

Conclusions:

• NCM exhibits characteristics consistent with chronic pain syndromes associated with CSS.
• Multidisciplinary and integrative treatment approaches may enhance outcomes for NCM.
• Cognitive therapies combined with integrative approaches show promise for managing NCM.
