Abstract
The debate regarding the two possible roles of lymphadenectomy in surgical oncology, prognostic or therapeutic, is still ongoing. Furthermore, the use of lymphadenectomy as a proxy for the quality of the surgical procedure is another feature of discussion. Nevertheless, this reckoning depends on patient conditions, aggressiveness of the tumor, the surgeon, and the pathologist, and then it is not an absolute surrogate for the surgical quality. The international guidelines recommend a minimum of 12 lymph nodes harvested for pathological examination in colorectal cancer (CRC) surgery. There is a growing literature on reporting better survival when the lymph node yield is high, even when these nodes are negative for malignancy. On the other hand, there are studies reporting no survival benefit with high lymph node yield in stage I-II of CRC. Herein we review the roles of the lymphadenectomy in CRC, and discuss the results of studies on lymph node harvesting.
