Diagnostic and prognostic potential of the resident non-small cell lung cancer microbiome.
The data of a comprehensive comparative study of the taxonomic composition of the resident microbiome of tumors from 26 patients with non-small cell lung cancer are presented. Analysis of taxonomic diversity revealed 10 types, 280 genera and 788 species of microorganisms. The analysis of the relative content and prognostic significance was carried out for 62 dominant genera. Differences in the relative abundance of bacteria of the genera Acinetobacter, Halomonas, and Chryseobacterium between tumor and conditionally normal lung tissue were found, but their diagnostic potential was not confirmed. The correlation analysis did not reveal any relationship between the content of various genera of bacteria and the histological type of the tumor, its localization, and the age of the patients. Differences were found in the content of the studied bacteria depending on the stage of the disease, the presence of regional metastases and tumor differentiation. The prognostic significance of bacteria of the genera Variovorax and Pseudoclavibacter in non-small cell lung cancer was established. The results obtained can be used in the development of new effective methods for the diagnosis and prognosis of non-small cell lung cancer.
