Prognostic importance of lymph node yield after curative resection of gastroenteropancreatic neuroendocrine tumours

Figure 1 Kaplan Meier curve of relapse-free survival according to lymph node yield in patients with gastroenteropancreatic neuroendocrine tumours who underwent resection of primary tumour and regional lymphadenectomy. Lymph node yield ≥ 8: P = 0.0365; Hazard ratio = 2.65; 95%CI: 1.06-6.62.

Figure 2 Kaplan Meier plot of relapse-free survival according to LN positivity in patients with gastroenteropancreatic neuroendocrine tumours who underwent curative resection. P = 0.0840; Hazard ratio = 2.62; 95%CI: 0.88-7.78.

Figure 3 Kaplan Meier plot of relapse-free survival according to tumour localisation: Pancreatic neuroendocrine tumours, small intestinal neuroendocrine tumours and others. Pancreas: P = 0.0063; Hazard ratio = 10.69; 95%CI: 1.95-58.56. Small intestine: P = 0.0043; Hazard ratio = 12.17; 95%CI: 2.19-67.69.
