Systemic inflammation in salivary gland cancer

Abstract

Relevance. The inflammatory process and endogenous intoxication of the patient’s body has a negative impact on the course of many malignant neoplasms, including salivary gland cancer.The objective of the study was to determine the influence of some factors of systemic inflammation and endogenous intoxication in salivary gland cancer.Methods and materials. A prospective study included the data of 59 patients with salivary gland cancer. The influence of peripheral blood parameters and relative indicators characterizing systemic inflammation on overall and disease-free survival was assessed.Results. As a result of the multivariate analysis, it was revealed that an increase in the level of the relative number of peripheral blood neutrophils by more than 60.08 % increases the risk of death in patients from salivary gland cancer by 3.90 times (p=0.0456; HR 3.90: 95 % CI 1.03–14.79). The level of the absolute number of peripheral blood lymphocytes, not exceeding 1.49x109 /l, increases the risk of disease progression by 8.72 times (p=0.0002, R 8.72: 95 % CI 2.78–27.28).Conclusion. Individual factors of systemic inflammation and endogenous intoxication, it is advisable to evaluate at the stage of planning the primary treatment of patients with salivary gland cancer, in order to determine the prognosis of the disease and optimize the choice of tactics for the primary treatment of patients.
