Figure 1. Liquid biopsy. Distant from the original tumor, samples from blood, CSF, or urine can serve as an easily acquired and low-risk source of tumor-derived nucleic acids (RNA and DNA) for further analysis to predict and monitor tumor progression and treatment response. CSF: Cerebrospinal fluid; CTC: circulating tumor cell; EV: extracellular vesicle; TEP: tumor educated platelets.
