Application and clinical efficacy of Sufu medical chitosan hydrogel dressing in radiation skin damage caused by radiotherapy for cervical cancer

Abstract

Objectives: To investigate the benefits of Sufu medical chitosan hydrogel dressing(Sufu) in the prevention and control of radiation skin damage during radiotherapy for cervical cancer as a combined modality. Methods: Ninety-seven cervical cancer patients who underwent radiotherapy at the Cancer Hospital of China Medical University between May 2017 and November 2018 were recruited according to given inclusion and exclusion criteria. The patients were assigned to a control group (n=48, washing the perineal area with normal saline) and an observation group (n=49, application of Sufu onto the site of radiotherapy in addition to washing the perineal area with normal saline). The treatment regimens for the two groups continued until the end of radiotherapy. A comparison of the RTOG (Radiation Therapy Oncology Group) grading of acute radiation-induced skin reactions (ARISRs), pain intensity (measured by the verbal rating scale (VRS)) and post-treatment wound healing was drawn between the two groups. Results: In the observation group, 81.6% (40/49) of the patients had radiation dermatitis, which was significantly lower than the incidence rate (95.8%, 46/48) in the control group (P <0.05). The observation group was at higher risk of radiation dermatitis when given a high radiation dose, while the control group was more likely to have radiation dermatitis when administered with a moderate radiation dose (P <0.05). The median time of occurrence of pain and the median time of onset of skin reactions were significantly later in the observation group as compared with the control group (P <0.05, respectively). In the observation group, the pain relief rate was 92.50% at Day-3, and the wound healing rate was 95.0% at Day-7, significantly higher than in the control group (73.9% and 80.4%) (P <0.05, respectively). Conclusions: During radiotherapy for cervical cancer, Sufu can effectively prevent and control radiation-induced skin and mucous membrane damage, delay the onset of radiation dermatitis and substantially reduce the incidence rate, relieve radiation dermatitis and pain and promote wound healing. doi: https://doi.org/10.12669/pjms.38.8.5569 How to cite this:He X, Hu X, Dong X, Li S, Ni Y.
