A case report of breast cancer recurrence with cystitis: the impact of immune checkpoint inhibitor therapy on the incidence of cystitis

Key Points

• Cystitis was observed as a rare immune-related condition linked to immune checkpoint inhibitors in breast cancer recurrence.
• The case highlights the specific immune-mediated mechanisms that may lead to increased cystitis incidence.
• Observational analysis of the adverse effects associated with immune checkpoint inhibitor therapy in cancer treatment.
• This finding supports the notion that further investigation is necessary to understand the underlying causes of cystitis.
