Presence of pancreatic intraepithelial neoplasia-3 in a background of chronic pancreatitis in pancreatic cancer patients
The clinical significance of pancreatic intraepithelial neoplasia (PanIN) lesions in non-neoplastic pancreata of pancreatic ductal adenocarcinoma (PDAC) patients remains controversial. As chronic inflammation has been recently demonstrated to promote dissemination of in situ precancerous lesions, we...

description | The clinical significance of pancreatic intraepithelial neoplasia (PanIN) lesions in non-neoplastic pancreata of pancreatic ductal adenocarcinoma (PDAC) patients remains controversial. As chronic inflammation has been recently demonstrated to promote dissemination of in situ precancerous lesions, we investigated the prognostic significance of PanINs associated with chronic pancreatitis (CP) in PDAC patients. This retrospective study analyzed 125 curatively resected PDAC specimens for the presence of PanIN and CP. Univariate and multivariate analyses were performed to identify significant predictive factors for poor disease-free survival (DFS) and overall survival (OS). Immunohistochemical staining for E-cadherin and S100A4, markers of epithelial-mesenchymal transition, was performed on resected specimens containing PanIN-3 lesions. CP was observed in 27.2% (34/125) and PanIN-3 in 25.6% (32/125) of specimens. In the presence of CP, PanIN-3 was significantly associated with decreased survival (DFS: 4.3 vs 15.5 months, P = 0.021; OS: 16.3 vs 30.9 months, P = 0.004). PanIN-3 was not a prognostic factor in the absence of CP. The presence of both PanIN-3 and CP was associated with a reduced survival compared to the other cases, in both univariate (DFS: P = 0.039; OS: P = 0.023) and multivariate (DFS: P = 0.020; OS: P = 0.076) analyses. Furthermore, E-cadherin loss and S100A4 expression were more frequently observed in PanIN-3 lesions of CP specimens than in those of non-CP specimens, although not statistically significant. PanIN-3 in association with CP is a significant prognostic factor for decreased survival in PDAC patients, suggesting that chronic inflammation may accelerate the progression of preinvasive high-grade PanIN. |
