Extranodal extension influences prognosis in pancreatic body/tail cancer: A retrospective cohort study
Background/Purpose
Extranodal extension (ENE) is an established prognostic factor in various malignancies, affecting survival in pancreatic head cancer (PHC). However, its significance in pancreatic body/tail cancer (PBTC) remains unclear. Therefore, we aimed to investigate the impact of ENE on PTBC prognosis.
Methods
We analyzed data collected from electronic medical records of patients with PBTC who underwent distal pancreatectomy at a single center between January 2011 and December 2015. The patients were categorized based on ENE presence and prognostic implications were evaluated using Kaplan–Meier survival curves and Cox proportional hazards model.
Results
PBTC cases involving lymph node (LN) metastasis and ENE exhibited significantly lower disease-free (DFS) and overall survival (OS) rates compared to cases without LN metastasis or ENE (median DFS; N0, 23 months; LN+/ENE−, 10 months; LN+/ENE+, 5 months; p < .001). No statistically significant difference was observed in DFS and OS rates between patients with N1/N2 in the group without ENE and those with ENE+. Multivariate analysis confirmed ENE as a significant adverse prognostic factor.
Conclusions
ENE significantly predicts poor prognosis in PBTC, particularly in cases with nodal metastasis. The current cancer staging system for PBTC should incorporate ENE status. Moreover, different staging systems should be considered for PHC and PBTC.
