Circulating Tumor Cells as Potential Biomarkers: Current Trends and Future Perspectives

Abstract

Subramanyam RV* and Nandini DB

Metastasis among the cancer patients results in poor prognosis and reduces overall survival drastically. Biomarkers of cancer are present in various body fluids and tissues which may be detected easily. Discovery of these biomarkers has led to tremendous improvement in diagnosis and clinical outcome of cancer patients. Circulating tumor cells (CTCs) are one such bio fluid based markers which have been extensively studied in current times as diagnostic, predictive and prognostic markers.
