The aim of the work: is to increase the effectiveness of radiation therapy of non-small cell lung cancer and squamous cell carcinoma of the head and neck by radiomodification with cyclooxygenase-2 inhibitors (celecoxibs) in combination with cytostatics (cisplatin) based on determining the mechanisms of their radiosensitizing action. Methods of research and equipment: clinical and instrumental, immunoassay, dosimetric, statistical; the immunoenzymometric analyzer Immunochem-2100, the universal dosimeter UNIDOS_E, the linear accelerator Clinac-600. Theoretical and practical results: it is established that the frequency of regressions during irradiation on a linear accelerator in the mode of classical fractionation in combination with COX-2 inhibitor and cisplatin in patients with GDR increases by 13.3%, reaches 83.3%, due to the number partial regressions, in patients with PRGS - 40% due to complete regressions. A comparative analysis of VEGF changes in radiation therapy (PT) showed that a more pronounced decrease in VEGF was observed after PT in combination with cisplatin and COX-2 inhibitor-ranselex than in PT in combination with ranselex alone, which increases inhibition of angiogenesis. Novelty: for the first time, scientific data were obtained on the mechanisms of radiation therapy in combination with COX-2 inhibitor - rancelex and cisplatin on the content of proangiogenic factor VEGF and inducers of angiogenesis COX-2 and PGE-2 in the serum of patients with NDRL and PRGS. Implementation efficiency: improving the effectiveness of treatment. Domain of usage: radiation oncology. Product Description popup.authors Artiukh Serhii V. Bilozor Nataliya V. Grebinyk Lidiya V.
