Current progress in research of circulating tumor cells / 南方医科大学学报

ABSTRACT

Circulating tumor cells are tumor cells that spontaneously or, following operations, migrate into the peripheral blood circulation from the primary tumor or metastatic tumor. As diagnostic, prognostic and predictive biomarkers in many types of cancers including breast cancer, lung cancer, pancreatic cancer and colorectal cancer, circulating tumor cells contribute to the early diagnosis of cancers, drug resistance monitoring, prognostic assessment, survival analysis, detection of tumor recurrence and evaluation of drug efficacy to assist in treatment decision?making and adjustment of treatment plans. However, the current approaches to the detection of circulating tumor cells still have limitations, and the development of new detection methods with higher sensitivity and specificity will be helpful for better use of these cells. Herein the authors review the research progress in circulating tumor cells in terms of the detection techniques, clinical applications of circulating tumor cells, and their prospects in future clinical practice.
