Core Tip

Core tip: Lymphadenectomy of colorectal cancer is a decisive factor for the prognostic staging of the patient. A limit of 12 lymph nodes (LNs) is still not the gold standard and accessible only in highly specialized centers. There are different variables that can affect the retrieval of LNs; some are non-modifiable and pose the question of whether the minimum number of examined LNs must be individually assigned.
