Abstract
In recent years, several types of platelet concentrates have been investigated and applied in many fields, particularly in the musculoskeletal system. Platelet-rich fibrin (PRF) is an autologous biomaterial, a second-generation platelet concentrate containing platelets and growth factors in the form of fibrin membranes prepared from the blood of patients without additives. During tissue regeneration, platelet concentrates contain a higher percentage of leukocytes and a flexible fibrin net as a scaffold to improve cell migration in angiogenic, osteogenic, and antibacterial capacities during tissue regeneration. PRF enables the release of molecules over a longer period, which promotes tissue healing and regeneration. The potential of PRF to simulate the physiology and immunology of wound healing is also due to the high concentrations of released growth factors and anti-inflammatory cytokines that stimulate vessel formation, cell proliferation, and differentiation. These products have been used safely in clinical applications because of their autologous origin and minimally invasive nature. We focused on a narrative review of PRF therapy and its effects on musculoskeletal, oral, and maxillofacial surgeries and dermatology. We explored the components leading to the biological activity and the published preclinical and clinical research that supports its application in musculoskeletal therapy. The research generally supports the use of PRF as an adjuvant for various chronic muscle, cartilage, and tendon injuries. Further clinical trials are needed to prove the benefits of utilizing the potential of PRF.

Abstract
Aim In advanced gastric cancer, symptoms such as loss of appetite, stomach tightness, occasional pain, vomiting blood, and melena may occur. Palliative radiation therapy may be indicated in such cases. This study aimed to investigate the clinical outcomes of palliative radiotherapy in patients with advanced-stage gastric carcinoma. Methods From April 2018 to October 2022, consecutive patients with non-resected advanced gastric cancer who received radiation therapy for palliation of symptoms were included. Results A total of 23 patients with advanced-stage gastric carcinoma were analyzed in this study. Twelve male and 11 female patients were included. The median overall survival period was 3.9 months (95% confidence interval: 1.0-8.7 months). Sixteen patients required erythrocyte transfusion before radiotherapy; for 13 patients (83%), the required units of erythrocyte transfusion decreased after palliative radiotherapy. The mean erythrocyte transfusion units significantly decreased from 4.2 (standard deviation [SD]: 4.3) to 1.7 (SD: 3.6) (p = 0.02). No adverse events of grade ≥3 were observed in this study population. Conclusion Palliative radiation therapy for advanced gastric cancer yielded a good response rate and can be a useful treatment option.
