Notably, a higher level of NEFM expression correlated with favorable OS of pancreatic ductal adenocarcinoma, pheochromocytoma and paraganglioma, whereas with poor OS of kidney renal clear cell carcinoma, lung adenocarcinoma, stomach adenocarcinoma, bladder carcinoma, head–neck squamous cell carcinoma, ovarian cancer and sarcoma as demonstrated in Kaplan–Meier plotter databases. Here, NEFM is linked to paraganglioma.
