Mesenchymal circulating tumor cells and Ki67: Their mutual correlation and prognostic implications in hepatocellular carcinoma

Mesenchymal circulating tumor cells (M-CTCs) may be related to tumor progression, and Ki67 expression is known to be involved in tumor proliferation. The aim of the present study was to explore the relationship between M-CTCs and Ki67 in hepatocellular carcinoma (HCC) and their ability to predict prognosis.
