Lymph Node Retrieval after Preoperative Chemoradiotherapy for Rectal Cancer

Journal of Gastrointestinal Surgery, 05/29/2012

Preoperative chemoradiotherapy reduces the lymph node yield in rectal cancer. The number of retrieved lymph nodes is affected by degree of histopathologic response of the tumor to chemoradiation. Thus, number of lymph nodes should not be used as a surrogate for oncologic adequacy of resection after neoadjuvant chemoradiotherapy for rectal cancer.
