The study aimed to determine the minimum number of regional lymph nodes (LNs) required to accurately stage adenocarcinoma of the appendix (AC). The researchers analyzed data from 3,602 AC patients and found that harvesting at least ten LNs was necessary to minimize the risk of missing LN-positive disease. Examining fewer than ten LNs was an independent negative prognostic factor for overall survival. Thus, an adequate number of regional LNs must be assessed to determine LN status in AC patients.
