    Abstract:
    Recurrent respiratory papillomatosis is a viral-induced disease, associated with exophytic epithelial lesions affecting the upper airways. Problem of treatment is the high recurrence of papilloma growth after surgical removal; therefore, adjuvant therapy schemes have been established. We used cidofovir, 7.5 mg/ml, in adjuvant therapy in the past years. Out of 31 adult patients treated with the drug, 26 (83.9 %) are at the moment in complete response. 19 (73 % of pts with CR) of those 26 patients were cured with a number of injections between 1 and 4 (mean 2.5). We did not see any clinical manifestation of renal toxicity or neutropenia (superinfection) necessitating a blood test. Six patients presented dysplasia during the treatment with the drug, while six patients had dysplasia prior to cidofovir injection. Due to recurrent nature of the disease and the high number of mechanical and laser surgeries required we treated one tracheal stenosis, two scarred larynx, and two glottic synechiaes. There is still an ongoing discussion within the European Laryngological Society about the effectiveness and possible side effects of this drug. Results show promising long-term effects of adjuvant use of cidofovir, without any relevant side effects.
