The primary aim of this study was to assess the efficacy and mechanism of hyperbaric oxygen therapy （HBOT） to reduce the keloid recurrence rate after surgical excision and radiotherapy. Methods： （1） A total of 240 patients were randomly divided into two groups. Patients in the HBOT group （O group） received HBOT after surgical excision and radiotherapy. Patients in the other group were treated with only surgical excision and radiotherapy （K group）. （2） Scar tissue from recurrent patients was collected after a second operation. Hematoxylin and eosin （H＆E） staining was used to observe keloid morphology. Certain inflammatory factors （interleukin-6 （IL-6）, hypoxia-inducible factor-1α （HIF-1α）, tumor necrosis factor-α （TNF-α）, nuclear factor KB （NF-κB）, and vascular endothelial growth factor （VEGF）） were measured using immunohistochemical staining. Results： （1） The recurrence rate of the O group （5.97%） was significantly lower than that of the K group （14.15%）, P〈0.05. Moreover, patients in the O group reported greater satisfaction than those in the K group （P〈0.05）. （2） Compared with the recurrent scar tissue of the K group, the expression levels of the inflammatory factors were lower in the recurrent scar tissue of the O group. Conclusions： Adjunctive HBOT effectively reduces the keloid recurrence rate after surgical excision and radiotherapy by improving the oxygen level of the tissue and alleviating the inflammatory process.展开更多
