Isolation by size of epithelial tumor cells in peripheral blood of patients with breast cancer: correlation with real-time reverse transcriptase-polymerase chain reaction results and feasibility of molecular analysis by laser microdissection.

The aim of this study is the counting and the immunomorphological and molecular characterization of circulating tumor cells (CTCs) by the isolation by size of epithelial tumor cells (ISET) method in the peripheral blood of patients with breast cancer. An evaluation of the method's ability to reveal the presence of occult carcinoma cells in blood of a… CONTINUE READING
