About

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.

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 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.

Sex: All

Volunteers: No Healthy Volunteers

Inclusion criteria

1. Older than 18 years;
2. Patients with any oncological etiology;
3. With the presence of established radiodermatitis RTOG II or III;
4. Patients who are undergoing palliative oncological care and RD standard treatment;
5. Patients who do not present clinical signs of another pathology that justifies the presence of the skin lesion;
6. Patients do not have local skin infection

Exclusion criteria

• Critical clinical states;
• Patients with skin lesions of another cause even when undergoing RT;
• Patients referred to the laser clinic for the prevention of radiodermatitis without the active RD lesion.
• Patients who have used another photobiomodulation therapy protocol foresaw injury not related to the study.
• All contraindications already defined in the routine referral to the outpatient clinic (patients who have an active tumor at the site to be irradiated; individuals with a history of photosensitivity to photonic or light therapy; patients who have undiagnosed lesions in the treatment region; patients using topical photosensitizing medications or creams; cognitive, psychiatric or neurological changes that prevent the free understanding of the PBM therapy
