Low-Dose Cisplatin-Based Radiation Therapy for Refractory Recurrent Respiratory Papillomatosis.

Recurrent respiratory papilloma (RRP) often presents multiple lesions in the respiratory tract and sometimes becomes fatal because of severe airway obstruction. We report the case of a 69-year-old woman who had juvenile-onset RRP in the trachea that was refractory to surgical treatment, and complete remission was achieved by low-dose cisplatin combined with de-escalated radiotherapy without any side effects. This case report is the first to illustrate the data on low-dose cisplatin for refractory benign RRP, and our experience reinforces the opinion that low-dose cisplatin combined with de-escalated radiotherapy can be an effective and safe treatment alternative for uncontrollable and lethal RRP.
