Circulating tumor cell-based tailor-made therapy for hepatocellular carcinoma

We detected telomerase-positive cells in the peripheral blood of hepatocellular carcinoma using a new method “TelomeScan”. We confirmed that most of the cells we detected were circulating tumor cells, which was a promising marker of metastasis. Interestingly, we detected the cells even in early stages, indicating another factor is needed to form metastatic lesions. We could not completely overcome the problems of false-positive and false negative and they must be addressed in the future.
