Immunophenotype of isolated tumour cells in the blood, bone marrow and lymph nodes of patients with gastric cancer.

Immunophenotype of isolated (disseminated or circulating) tumour cells (ITC) in the blood, bone marrow and lymph nodes were studied in patients with gastric cancer. Coexpression of metalloproteinases inducer (EMMPRIN), chemokine receptors (CCR6, CXCR4) and adhesion molecules (Ep-CAM, CD44) was determined on cytokeratin positive (CK + ) cells in CD45 – cell population
