Long-term outcome and prognostic factors for patients with para-aortic lymph node dissection in left-sided colorectal cancer

Authors:

Abstract
Para-aortic lymph node (PALN) metastasis of colorectal cancer is rare, and the treatment strategy for PALN metastasis (PALNM) is not established in contrast to liver or lung metastases. We sought to evaluate the survival outcomes and prognostic factors among patients undergoing surgery combined with extended lymphadenectomy for PALNM from left-sided colorectal cancer.
