podophyllin and Tongue-Neoplasms

The aim of this study was to present a new topical treatment protocol for oral hairy leukoplakia (OHL), consisting of a 25% podophyllin resin with a 1% penciclovir cream (PP), and to compare this topical treatment protocol's efficacy with that of 2 other topical treatment protocols: a 25% podophyllin resin (P) and a 25% podophyllin resin with a 5% acyclovir cream (PA).. Forty-two human immunodeficiency virus-positive patients with 69 OHL lesions were randomly treated using P, PA, or PP (14 patients in each topical treatment protocol). Clinical healing was determined when the white plaque could no longer be seen in the primary location of the lesion. Topical treatment performance was evaluated by clinical healing within each week of topical treatment protocol as well as by the recurrence of the lesion. Statistical survival analysis was performed using a Cox proportional hazards model.. Approximately 55% of the patients presented with clinical healing of OHL within 7-8 weeks of each topical treatment protocol. After the sixth week, the PA treatment protocol presented a faster clinical healing rate of OHL. Recurrence was observed in 3 and 7 OHL lesions treated with P and PP treatment protocols, respectively.. The PP treatment protocol proved to be effective; however, the PA treatment protocol was more effective in the clinical healing rate for OHL than P and PP after the sixth week of treatment, and no recurrent OHL was observed in the PA treatment group.

Ten HIV-infected patients who had bilateral hairy leukoplakia on the tongue were treated with topical podophyllum resin 25% solution. Only one side of the bilateral lesion was treated and the other side served as the control and was not treated. The lesions on both the treatment and control sides were evaluated at day 2, 7, and 30 by an investigator who had not been involved in the initial treatment and had no knowledge of which side had been treated. Therefore the treatment side is compared with the control side in a single-subject design, single-blind control setting. The lesions were judged by the degree of resolution and assigned a number of 0 to 4 with 4 indicating the highest degree of resolution and 0 indicating no resolution or worsening of the condition. The results were analyzed by Student's t test. Significant resolution of hairy leukoplakia was noted on the treatment side compared with the control side at the 2-, 7-, and 30-day levels; the 2-day results were the most significant. Furthermore, the patients reported minimal side effects, which included burning sensation, bad or altered taste, and pain, that were of mild intensity and short duration. The side effects were reported to occur immediately after the topical application. Patient tolerance and acceptance were found to be very favorable. No systemic side effect was reported. We conclude that single topical application of podophyllum resin 25% solution is efficacious in producing significant short-term resolution of HIV-related oral hairy leukoplakia. We also conclude that it is a safe topical regimen with minimal side effects.
