At the same time, for the first time, we revealed that a high bacterial load of an immunosuppressed tumor (with a large number of FOXP3 + cells) is a marker of a poor prognosis in NSCLC compared with a group with a high bacterial load and low FOXP3 content (HR 4.651 (1.362–15.88); p = 0.0116; Figure 7). This evidence concerns the gene FOXP3 and neoplasm.
