Conclusions:Conclusions:• It was revealed that recognition of lung cancer patients with It was revealed that recognition of lung cancer patients with
distant metastases from lung cancer patients without distant distant metastases from lung cancer patients without distant metastases significantly depended on: metastases significantly depended on:
• 1) level of B-cell circuit; 1) level of B-cell circuit; • 2) value of K-cell circuit; 2) value of K-cell circuit; • 3) level of humoral immunity; 3) level of humoral immunity; • 4) neutrophils circuit; 4) neutrophils circuit; • 5) value of cell ratio factors (ratio of cancer cell population to 5) value of cell ratio factors (ratio of cancer cell population to
immune cell subpopulations in integral patient organism); immune cell subpopulations in integral patient organism); • 6) lung cancer characteristics (T1-4, N0-3,G1-3, histology, tumor 6) lung cancer characteristics (T1-4, N0-3,G1-3, histology, tumor
