Current approaches to diagnosing and treating idiopathic granulomatous mastitis: A summary from in-depth clinician interviews.

BACKGROUND

Idiopathic granulomatous mastitis (IGM) is a rare, chronic inflammatory breast condition primarily affecting women of reproductive age. Its diagnosis is challenging due to similarities with other breast disorders, necessitating exclusion of other granulomatous diseases. The management of IGM remains inconsistent and unclear, with high recurrence rates and varying practices.

METHODS

This qualitative study involved semi-structured interviews with nine clinicians from Singapore, Malaysia, and Egypt to examine current diagnostic and therapeutic approaches for IGM. Transcripts were analysed using NVivo software for coding and summarisation.

FINDINGS

Clinicians predominantly used imaging and histopathology for diagnosis. Treatment commonly involved corticosteroids, though dosages and tapering regimens varied widely. Methotrexate was used sparingly for refractory cases due to associated risks. Surgical interventions were infrequent, reflecting a preference for medical management. There was a consensus on the need for randomised controlled trials (RCTs) to establish standardised treatment protocols.

INTERPRETATION

This study reveals the complex nature of IGM diagnosis and treatment from clinicians in Singapore, Malaysia and Egypt. This underscores the need for more specific and definitive diagnostic tests, rather than relying on exclusionary methods, and standardised treatment guidelines. Multi-centre RCTs are essential for developing evidence-based protocols to improve patient outcomes and address regional differences effectively.
