Minimum Number of Lymph Nodes Required for Staging Adenocarcinoma of the Appendix

Researchers aimed to determine the minimum number of lymph nodes (lns) needed to accurately stage adenocarcinoma of the appendix. They analyzed data from 3,602 patients and found that harvesting at least ten lns was necessary to minimize the risk of missing lymph node positive (lnp) disease. Failing to evaluate at least ten lns was also associated with a negative impact on overall survival.
