New Evidence of Emerging Nodal Metastasis in Staging System after Surgical pNET Resection as Predictive Factor for Recurrence. Result from Monocentric Retrospective Series


Introduction: New evidence is emerging of the role of pNETs lymphatic metastasis in terms of Oncological Outcomes. A specific staging classification is not actually available.

Aim(s): Aim of the present research is to validate the impact of metastatic nodes on Overall Survival (OS) and Disease Free Survival (DFS) according to the emerging evidence.

Materials and methods: Patients who underwent radical surgery for pNETs between 2003 and 2018 were identified and retrospective analyzed. Several data about demographic population, peri-operative outcomes, surgical procedure, tumor location, histopathology and follow-up Outcomes were recorded. Statistical analysis with univariate and multivariate analysis were performed while OS and DFS were compared using Kaplan Meier Curve.
