Hydrogen Peroxide Trial to Investigate the Efficacy of 30%H2O2 as a Topical Application Before Definitive Treatment

Summary

Previous work suggests that topical treatment with 33% hydrogen peroxide can reduce lesion size and, in about half of patients, can cause complete pathologic response. For patients with reduction in lesions size, the required size of the surgical excision or radiation field will be similarly decreased, thus potentially limiting associated morbidity and better cosmetic outcomes. Additionally, patients that experience a complete pathological response will be able to avoid additional treatment with either surgery or radiation. This will benefit both patients as well as helping to decreased use of health care resources. For the current study we will be using 30% hydrogen peroxide as it is commercially available. If this study shows positive results, it could lead to significant benefit on both a patient and systems level. Locally, our cancer Centre treats approximately 700 new patients per year who fit into the study criteria and could potentially benefit from this novel neoadjuvant treatment that is fairly inexpensive.

Hydrogen Peroxide 30 % Topical Solution

Patients will be seen by the radiation therapists involved with the study after randomization. Prior to application of hydrogen peroxide solutions, the patients' lesions will be prepared and debrided of keratinous debris and oils using sterile 70% isopropyl alcohol. Then, the appropriate hydrogen peroxide solution (30% for Arm 1 or 3% for Arm 2) will be rubbed into the lesion and a 1cm border all around the lesion until blanching of the lesion is observed. Hydrogen peroxide will be reapplied after one hour. This process will be repeated weekly for three additional applications for this study. If there is complete clinical response, further hydrogen peroxide will not be done. Patients will be accessed for definitive treatment 4 weeks later.
