The Prognostic Impact of Extracapsular Lymph Node Involvement (ECLNI) in Ductal Pancreatic Adenocarcinoma (DPAC).
Presence and extent of extracapsular lymph node involvement (ECLNI) will be scored by

ECLNI is defined as metastatic adenocarcinoma extending through the nodal capsule into the
perinodal fatty tissue.
Observers: 1 experienced board-certified GI pathologist, blinded for follow-up results.
Follow-up data are obtained by reviewing patients charts and by a telephone survey of the
patient's GP/gastroenterologist in November 2007.
