The study included 425 patients with lung cancer of various histological types. Saliva samples were collected before treatment and 34 biochemical parameters were determined. Prognostic factors were analyzed by multivariate analysis using Cox’s proportional hazard model. Results have shown that for squamous cell carcinoma, LDH activity below 1748 U/L was an independent prognostically unfavorable factor (HR = 2.89; 95% CI 1.28 – 6.46; р = 0.00330). For adenocarcinoma, there was a combination of factors: the content of imidazole compounds above 0.311 mmol/L, seromucoids below 0.098 c.u. and uric acid less than 83 nmol/mL (HR = 7.91; 95% CI 2.52 – 24.11; р = 0.00004). For neuroendocrine lung cancer, an unfavorable prognosis was associated with the urea content below 8 mmol/L, NO below 24 nmol/mL and ALP activity below 74 E/L (HR = 12.50; 95% CI 1.09 – 138.7; р = 0.01184). For radical surgery, an unfavorable prognosis was associated with LDH activity below 545 U/L (HR = 7.20; 95% CI 2.13 – 23.70; p = 0.00968), for combined treatment, with the NO level below 15 nmol/mL (HR = 5.64; 95% CI 1.89 – 16.46; p = 0.02797). The worst prognosis for palliative treatment was observed at the NO level below 24 nmol/mL and the imidazole compound content above 0.311 mmol/L (HR = 2.73; 95% CI 1.07 – 12.92; р = 0.01827). The identified parameters can be used to predict lung cancer and personalized patient’s treatment.</p>}, number={3}, journal={Biomedical Chemistry: Research and Methods}, author={Bel’skaya, L.V. and Kosenok, V.K.}, year={2020}, month={Sep.}, pages={e00133} }
