Detection of disseminated tumor cells and their relationship with a population of bone marrow lymphocytes in patients with non-small cell lung cancer
Introduction.Detection of disseminated tumor cells (DTC) in solid tumors is an important component of the assessment of disease prognosis. Bone marrow damage is common. There is evidence indicating an important role for bone marrow lymphocyte subpopulations in hematogenous metastasis. Aim.To eval...

Materials and methods.62 bone marrow samples of patients with a verified diagnosis of NSCLC: adenocarcinoma (33), squamous cell carcinoma (27), other types (2).

Results.In bone marrow, DTC (EPCAM+CD45-) were found in 43.5% of patients with NSCLC (1 cell per 10 million myelocariоcytes was taken as the threshold value). The presence of DTC did not correlate with the size of the tumor, the status of the lymph nodes, and the stage of the tumor process.

Conclusion.The possibility of detecting DTC in the bone marrow of patients with NSCLC was established, in 43.5% of patients with NSCLC in the bone marrow DTC was detected, and their presence was established even with a localized tumor process.
