Core Tip

Core Tip: The present study utilized data extracted from a publicly available Surveillance, Epidemiology, and End Results database and employed multivariate cox analysis, revealing that lymph node ratio (LNR), positive lymph node (PLN), and log odds of PLNs (LODDS) staging systems was significantly related to mortality among patients with colorectal neuroendocrine neoplasms treated surgically. Additionally, the LODDS staging demonstrated a higher prognostic value compared to the PLN and LNR staging systems.
