Studies conducted on PCAT19 in prostate cancer and laryngeal cancer (Gao, Xia, et al. [26], Xu, Guo, and Zhang [15]) demonstrated that aggressiveness of prostate cancer is positively associated with increased expression of PCAT19 Gao, Xia, et al. [26], and upregulation of PCAT19 in laryngeal tumor tissue is associated with shorter overall survival time (Xu, Guo, and Zhang [15]). This evidence concerns the gene PCAT19 and laryngeal carcinoma.
