Hua J, et al. - Researchers investigated the ideal number of examined lymph nodes (ELNs) for accurate staging of pancreatic cancer using the nodal staging score model by assessing clinicopathological data for patients with resected pancreatic cancer from the Surveillance, Epidemiology, and End Results (SEER) database (development cohort) and Fudan University Shanghai Cancer Center database (validation cohort). Outcomes revealed that T stage influenced the optimal number of ELNs for adequate staging of pancreatic cancer. Examination of at least 16, 21, and 23 LNs was recommended for T1, T2, and T3 tumors, respectively, as a nodal staging quality measure for both surgery and pathological analysis.
