Abstract
This review explores the mechanisms of chronic radiation-induced skin injury fibrosis, focusing on the transition from acute radiation damage to a chronic fibrotic state. It reviewed the cellular and molecular responses of the skin to radiation, highlighting the role of myofibroblasts and the significant impact of Transforming Growth Factor-beta (TGF-β) in promoting fibroblast-to-myofibroblast transformation. The review delves into the epigenetic regulation of fibrotic gene expression, the contribution of extracellular matrix proteins to the fibrotic microenvironment, and the regulation of the immune system in the context of fibrosis. Additionally, it discusses the potential of biomaterials and artificial intelligence in medical research to advance the understanding and treatment of radiation-induced skin fibrosis, suggesting future directions involving bioinformatics and personalized therapeutic strategies to enhance patient quality of life.

Abstract
Radiation injury has a complex pathophysiology and can result in long-term impediment of the dermal barrier function. Historically, its treatment has been no different to that of thermal burns and it is not always possible to prevent an unpredictable and uncontrolled extension of the radiation-induced reactions. Non-invasive physical plasma (NIPP), a highly energised gas encompassing a combination of various reactive species, positively affects the key players involved in wound healing and proves to be a promising treatment option for chronic wounds and inflammatory skin disorders. Recent clinical evidence also suggests preliminary efficacy in radiation injury following therapeutic irradiation as a part of cancer therapy. Further research is warranted to also investigate the clinical value of NIPP in the context of unplanned or accidental radiation exposure, either as a topical treatment or possibly as an intraoperative procedure, to potentially improve the dermatological outcome and reduce symptoms in radiation victims.

Abstract
Ionizing radiation causes injury to the skin that produces a complex clinical presentation that is managed by various paradigms without clear standards. The situation is further complicated by the fact that clinicians and researchers often use different terms and billing codes to describe the spectrum of cutaneous injury. There is, however, general agreement between the two most commonly-used diagnostic scales, the Radiation Therapy Oncology Group and the Common Terminology Criteria for Adverse Events, and in their use to describe skin injury following radiation therapy. These scales are typically used by radiation oncologists to quantify radiation dermatitis, a component of the radiation-related disorders of the skin and subcutaneous tissue family of diagnoses. In rare cases, patients with severe injury may require treatment by wound care or burn specialists, in which case the disease is described as a “radiation burn” and coded as a burn or corrosion. Further compounding the issue, most US government agencies use the term Cutaneous Radiation Injury to indicate skin damage resulting from large, whole-body exposures. In contrast, the US Food and Drug Administration approves products for radiation dermatitis or “burns caused by radiation oncology procedures.” A review of the literature and comparison of clinical presentations shows that each of these terms represents a similar injury, and can be used interchangeably. Herein we provide a comparative review of the commonly used terminology for radiation-induced skin injury. Further, we recommend standardization across clinicians, providers, and researchers involved in the diagnosis, care, and investigation of radiation-induced skin injury. This will facilitate collaboration and broader inclusion criteria for grant-research and clinical trials and will assist in assessing therapeutic options particularly relevant to patient skin pigmentation response differences.

Abstract
Background: Radiation skin injury (RSI) causes changes in skin temperature, but detailed information on the thermographic responses is currently lacking. We investigated thermographic patterns after radiotherapy. We hypothesized that skin temperature may be used as a diagnostic and early predictor of RSI severity.Method: All breast cancer patients received radiotherapy after unilateral postmastectomy. The contralateral supraclavicular area served as control, and the frontal thermal image of torso was taken by a thermal infrared imager weekly. We defined areas of interest on bilateral symmetrical supraclavicular area, and analyzed the difference of average and maximum skin temperature (DSTaverage and DSTmax) between them. The extent of the weekly variation in DST (DSTW) was calculated using a mathematical formula to represent a trend of skin temperature change. RSI and symptoms related to RSI were scored from baseline to 2 weeks after the end of radiotherapy.Results: Forty-one patients were enrolled in this study. In comparison to the baseline, the DSTaverage and DSTmax increased significantly over time during radiotherapy (p < .05). The onset of DST increase was accompanied by the onset of radiation dermatitis, and the maximal DST also appeared at the peak of Radiation Therapy Oncology Group (RTOG) and symptom scores. Radiation dose, DSTaverage, burning-feeling and pulling were the independent variables affecting RTOG score according to multivariate analysis (p < .001, p < .034, p < .001, p < .001). Patients with DSTWaverage >1.223 or DSTWmax >1.114 in second week showed a late higher dermatitis score (RTOG score ≥2).Conclusion: This study confirmed that RSI was associated with thermographic response. Our results suggested that the follow-up observations of skin temperature during radiotherapy could provide the objective evaluation criteria and prediction methods for RSI.

Abstract
A porcine skin model was developed to characterize the dose-dependent response to high-dose radiation. The dorsal skin of a mini pig was divided into four paraspinal sections, with 11 small irradiation fields (2 cm × 2 cm) in each section, and a single fraction of 15, 30, 50 or 75 Gy was delivered to each section using a 6 MeV electron beam. A spectrophotometer measured gross skin changes, and a biopsy for each radiation dose was performed in the 1st, 2nd, 4th, 6th and 9th weeks for histology, immunostaining with anti-CD31, and western blotting with IL-6 and TGF-β1 to determine the degree of skin damage. After a 4-week latency period, erythema and dry desquamation, moist desquamation, and ulceration appeared at 4, 6 and 9 weeks, respectively. Gross skin toxicity was more pronounced, occurred early and continued to progress with irradiation >50 Gy, whereas complete healing was observed 12 weeks after 15 Gy. Spectrophotometry showed erythema indices rapidly increased during the first 4 weeks after irradiation. The number of eosinophils began rising sharply at 4 weeks and normalized after reaching peaks at 7-8 weeks. Microvessel density showed a biphasic pattern with a transient peak at 1 week, a nadir at 4-6 weeks, and maximum recovery at 9 weeks. Increase in the levels of IL-6 and TGF-β1 was detected soon after irradiation. Most of these parameters indicated complete healing of the skin 12 weeks after 15 Gy. Our porcine skin model provides an effective platform for studying high-dose radiation-induced skin injury, in particular histologic and molecular changes, during the early latency period.
