Patients with resected, histologically re-confirmed pancreatic ductal adenocarcinoma (PDAC) can achieve long-term survival despite T3 tumour or nodal involvement. The Finnish Register Study 2000-2013

This is the largest single-nationwide cohort of long-term survivors with confirmed PDAC. Comprehensive pathological evaluation is mandatory for an adequate PDAC diagnosis and true survival analysis. Long-term survival can be achieved even in T3 patients with nodal involvement and may be explained by favorable tumour biology.
