Clinical significance of the number of lymph nodes detected for stage Ⅱ colorectal cancer / 国际外科学杂志

ABSTRACT

Colorectal cancer is a threat to human health, the disease rate of stage Ⅱ colorectal cancer is increasing. Some prognostic factors have been researched, and the number of harvested lymph nodes is a very important factor. Harvesting more lymph nodes will reduce the relapse rate and increase the survival rate. It remains controversial for the minimum number of lymph nodes, and UICC and AJCC recommended that the minimum number was 12. Some factors will influence the number of harvested lymph nodes,for ex-ample, the patient's situation, tumor itself, surgeon and pathologist's skills , and so on.
