Comparative study on the sustained efficacy of diphencyprone immunotherapy versus cryotherapy in viral warts.

摘要

This study compared the sustained clearance rate of viral warts treated with topical diphencyprone (DCP) therapy (group A) versus cryotherapy (group B). After 12 months follow-up, 93.3% (42/45) of group A and 76.3% (29/38) of group B presented sustained clinical clearance. Our data suggest that topical DCP therapy may lead to the induction of the long-term immunity to human papillomavirus (HPV).
