- Brief Summary
It is estimated that there will be 670,000 new cases of cancer worldwide in 2020-2022 and it is known that the most commonly instituted treatments in cancer are chemotherapy, radiotherapy and surgery. However, these treatments have undesirable side effects, such as Radiodermatitis after Radiotherapy (RD). In fact, the prevalence of possible side effects after radiotherapy is estimated to be 80 to 90%. Radiotherapy complications are associated with a negative impact on patients' quality of life and few supportive measures are available for such complications. Thus, the management of these side effects has been studied in the literature until the present day. On the other hand, Photobiomodulation (PBM) has an important role in wound repair and tissue regeneration, as it influences the different phases of lesion resolution, including the inflammatory phase, the proliferative phase and the remodeling phase. Thus, the aim of this study is to report a case series of Cancer Patients diagnosed with radiotherapy-induced acute radiodermatitis on Palliative Care, treated with PBM. This is a case series report and the study data will be extracted from the medical records of forty cancer patients with grade 2 or 3 RD followed up from September 2023 at the Laser Therapy Outpatient Clinic in a Universitary Hospital. The outcomes are the size of the lesion, the presence of pain assessed by the Visual Analogue Scale (VAS), the Portuguese Version of WHOQOL BREF Scale and the RTOG Scale (Radiation Therapy Oncology Group Scale) to assess the degree of Radiodermatitis before and after PBM therapy. The data will be subjected to a statistical analysis and will be discussed. Data with positive or negative results will be reported.

Thus, the aim of this study is to report a case series of forty cancer patients on palliative care diagnosed with radiotherapy-induced acute radiodermatitis Grade 2or 3, treated with PBM. This is a case series report and the study data will be extracted from the medical records of patients with grade 2 or 3 RD followed up from September 2023 at the Laser Therapy Outpatient Clinic in a Universitary Hospital. The outcomes are the size of the lesion, the presence of pain assessed by the Visual Analogue Scale (VAS), the Portuguese Version of WHOQOL BREF Scale and the RTOG Scale (Radiation Therapy Oncology Group Scale) to assess the degree of Radiodermatitis before and after PBM therapy. The assessment will be done pre-treatment, weekly during PBM therapy and post-treatment. The PBM therapy are focal low-level laser therapy, 1 to 3 Joules per point, depending on the degree of pain, wavelength 633 to 685 nm, transcutaneously on the surface of the tissue injured by radiotherapy, three times a week during radiotherapy treatment and two more applications after the end of radiotherapy The data will be subjected to a statistical analysis and will be discussed. Data with positive or negative results will be reported.

- Arm && Interventions
Group Intervention Description Radiodermatitis Case Group Photobiomodulation Therapy 40 patients on palliative care with grade 2 or grade 3 radiodermatitis after radiotherapy for the treatment of cancer submitted to a PBM therapy protocol
- Primary Outcome Measures
Name Time Method Lesion Size Change from Baseline at 14 days after end of radiotherapy treatment] Evaluation of lesion measurement in centimeters
Toxicity criteria of the Radiation Therapy Oncology Group Scale (RTOG Scale) Change from Baseline at 14 days after end of radiotherapy treatment] RTOG scale assess the degree and intensity of RD. It identifies degree 0 (no reaction), 1 (faint erythema, dry desquamation, epilation, diminished sweating), 2 (moderate, brisk erythema, exudative dermatitis in plaques and moderate edema), 3 (exudative dermatitis, besides cutaneous folds and intense edema) and 4 (ulceration, hemorrhage, necrosis).
Portuguese version of The World Health Organization Quality of Life Scale (WHOQOL-BREF) Change from Baseline at 14 days after end of radiotherapy treatment] The WHOWOL BREF scale assess multidimensional aspects of geral quality of life of patients. The multidimensional scale is composed by 26 items, classified from 1 to 5 according to the intensity of the symptom presented. The global score is calculated by adding up all the items as well as the score for each domain is evaluated adding it individually for each item, which can range from 0 to 130,
- Secondary Outcome Measures
Name Time Method Visual Analog Scale of Pain Change from Baseline at 14 days after end of radiotherapy treatment] VAS Scale assess the pain intensity. The VAS consists of a 10cm line, with two end points representing 0 ('no pain') and 10 ('pain as bad as it could possibly be').
