Impact on survival of the number of lymph nodes removed in patients with node-negative gastric cancer submitted to extended lymph node dissection
PURPOSE: This study was designed to establish whether the number of lymph nodes
removed has an effect on prognosis in patients with node-negative gastric cancer.
PATIENTS AND METHODS: We retrospectively analysed data of 114 consecutive patients
who underwent gastrectomy and extended lymph node dissection for node-negative
adenocarcinoma of the stomach between 2000 and 2005. Standard survival methods and
restricted cubic spline multivariable Cox regression models were applied. RESULTS …
