Cadaveric study reveals baseline regional lymph node counts in upper abdominal stations, highlighting undercounting in standard gastric cancer lymphadenectomy.

Key Points

To establish the true baseline anatomical number and distribution of regional lymph nodes in upper abdominal sites relevant to gastric cancer lymphadenectomy.
Examined regional lymph node stations defined by the Japanese Research Society for Gastric Cancer in N=30 cadavers.
Applied a tissue-clearing technique to dissolve fat and visualize all lymph nodes with a diameter of at least 1 mm.
Dissection of stations 1–11 (corresponding to R2 resection) revealed an average of 27 nodes (range: 17–44 nodes).
Dissection of stations 1–16 (corresponding to R3 resection) yielded an average of 43 nodes (range: 25–64 nodes).
Observed anatomical node counts exceeded typical surgical retrieval numbers and showed substantial individual variation across stations.
