A Neuroendocrine tumor cells in CRC detected by immunostaining for CgA (magnification x 100). B Neuroendocrine tumor cells in CRC detected by immunostaining for SYP (magnification x 100). C Relative expression of CgA in CRC and corresponding non-cancerous tissues from TCGA. ***P < 0.001. D Relative expression of SYP in CRC and corresponding non-cancerous tissues from TCGA. ***P < 0.001. E Kaplan–Meier curve analysis of the correlation of CgA expression and overall survival or progression-free survival from TCGA. F Kaplan–Meier curve analysis of the correlation of SYP expression and overall survival or progression-free survival from TCGA.
