Core Tip

Core Tip: A large database was analyzed to investigate survival outcomes related to lymph node assessment in locally advanced gastric cancer patients with radical gastrectomy. Independent of TNM-stage, the group with assessment of < 16 lymph nodes (LNs) had significantly worse survival than two other groups, 16-29 LNs and ≥ 30 LNs. Stage migration because of inadequate specimen analysis and improper lymphadenectomy was the main root cause.
