Cryotherapy No Better Than 50% Salicylic Acid, Costs More
Emma Hitt, PhD
September 26, 2011 — For the treatment of verrucae, cryotherapy using liquid nitrogen and patient daily self-treatment with 50% salicylic acid appear to result in similar efficacy outcomes, although cryotherapy is more expensive, according to the findings of a new randomized trial conducted in the United Kingdom.
Sarah Cockayne, MSc, from the Department of Health Sciences, York Trials Unit, University of York, United Kingdom, and colleague reported their findings in the September issue of Health Technology Assessment.
According to the researchers, it is estimated that almost 2 million people in England and Wales visit their general practitioner for the treatment of cutaneous warts each year, at a cost of £40 million. However, the “evidence base on which to inform clinical decision-making is poor,” according to the authors. In addition, they note, a 2006 Cochrane review of 60 studies concluded that a trial comparing topical salicylic acid with cryotherapy was “urgently needed.”
The current study, called the Effective Verruca Treatments trial, sought to assess the clinical effectiveness, acceptability, and cost-effectiveness of cryotherapy compared with salicylic acid for the treatment of verrucae.
