Lymph Node Ratio-based Staging System Outperforms the Seventh AJCC System for Gastric Cancer Validation Analysis With National Taiwan University Hospital Cancer Registry

摘要

Background: On the basis of SEER data, in which most gastric cancer patients had limited lymph node dissection, node ratio based staging system (TNrM) has been shown to have better accuracy than the AJCC TNM system. This study is to validate the result with patients from Taiwan, where D2 lymphadenectomy is routinely performed.
