Previous investigations have shown the efficacy of H<jats:sub>2<\/jats:sub>O<jats:sub>2<\/jats:sub> in treating skin conditions such as seborrheic keratosis and actinic keratosis. In an area like the face, reconstruction of excision defects and ultimately aesthetic outcomes are of utmost importance. Hydrogen peroxide may represent a simple yet effective method at shrinking non-melanoma skin cancers (NMSC) of the head and neck before they are excised. <\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p> Eleven consecutive patients presenting to our cutaneous malignancy clinic had their skin lesions evaluated by the senior author for participation in the study. Lesion length and width was measured. Hydrogen peroxide formulated at a concentration of 33% was rubbed into the lesion until blanching was observed. Lesions were re-measured at follow up. Excisional biopsy was then performed and histopathological diagnosis was obtained. Statistical analyses compared pre- and post-treatment lesion dimensions. <\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p> Seventeen biopsy-proven NMSC lesions were included in this investigation. Statistically significant reductions in the length ( p\u2009&lt;\u20090.001) and width ( p\u2009&lt;\u20090.001) were observed with H<jats:sub>2<\/jats:sub>O<jats:sub>2<\/jats:sub> treatment. For some lesions, H<jats:sub>2<\/jats:sub>O<jats:sub>2<\/jats:sub> was the sole treatment required, with post-treatment biopsy demonstrating no evidence of malignancy. Patients endured minimal discomfort during treatment and no long-term side effects were observed. Follow up at 6 months revealed no recurrences. <\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p> We have demonstrated a significant reduction in the size of multiple lesions after application of 33% hydrogen peroxide, simplifying definitive excision and reconstruction. Hydrogen peroxide demonstrated an ability to successfully treat non-melanoma skin cancers as well. <\/jats:p><\/jats:sec>","DOI":"10.1186\/s40463-020-00433-6","type":"journal-article","created":{"date-parts":[[2020,6,2]],"date-time":"2020-06-02T18:05:26Z","timestamp":1591121126000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":9,"title":["33% hydrogen peroxide as a Neoadjuvant treatment in the surgical excision of non-melanoma skin cancers: A case series"],"prefix":"10.1177","volume":"49","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9328-8266","authenticated-orcid":false,"given":"N.","family":"Mundi","sequence":"first","affiliation":[{"name":"Department of Otolaryngology \u2013 Head and Neck Surgery, London Health Sciences Centre, Victoria Hospital, University of Western Ontario, 800 Commissioners Road E, N6A 5W9, London, ON, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"K.","family":"Jordan","sequence":"additional","affiliation":[{"name":"Departments of Oncology and Biophysics, University of Western Ontario, London, Ontario, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"P.","family":"Doyle","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology \u2013 Head and Neck Surgery, London Health Sciences Centre, Victoria Hospital, University of Western Ontario, 800 Commissioners Road E, N6A 5W9, London, ON, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"C.","family":"Moore","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology \u2013 Head and Neck Surgery, London Health Sciences Centre, Victoria Hospital, University of Western Ontario, 800 Commissioners Road E, N6A 5W9, London, ON, Canada"},{"name":"Division of Facial Plastic and Reconstructive Surgery, Department of Otolaryngology \u2013 Head and Neck Surgery, University of Western Ontario, London, Ontario, Canada"},{"name":"Division of Surgical Oncology, Department of Oncology, University of Western Ontario, London, Ontario, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2020,1,1]]},"reference":[{"key":"bibr1-s40463-020-00433-6","doi-asserted-by":"publisher","DOI":"10.1097\/01.bcr.0000188296.85105.22"},{"key":"bibr2-s40463-020-00433-6","doi-asserted-by":"publisher","DOI":"10.1016\/S0021-9258(17)45394-4"},{"key":"bibr3-s40463-020-00433-6","unstructured":"Ancira M, Miller M, Inventors.
