Liquid biopsy initially analyzed only circulating tumor cells (CTCs), but now extends to the analysis of the many components released by the tumor in body effluents (mainly blood), including cell-free circulating DNA, mRNA, non-coding RNA, long non-coding RNA, glycoprotein, “tumor educated platelets” (TEPs), or vesicles such as exosomes (Poulet, Massias & Taly, 2019). This evidence concerns the gene ART4 and neoplasm.
