| Description | The aim of this study was to investigate the prognostic significance of membranous beta-catenin and cytoplasmic beta-catenin expression in pancreatic cancer patients (pts). One hundred pts with histologically verified exocrine pancreatic ductal adenocarcinoma were retrospectively studied. The membranous beta-catenin, cytoplasmic beta-catenin, and cell nucleus beta-catenin expression were immunohistochemically evaluated. The expression of membranous beta-catenin was <5% in none of the pts, 5-25% in one patient, 26-50% in 2 pts, 51-75% in 14 pts, and >75% in 81 pts. The expression of cytoplasmic beta-catenin was <5% in 34 pts, 5-25% in 42 pts, 26-50% in 18 pts, 51-75% in 3 pts, and >75% in one patient. The expression of beta-catenin in the cell nucleus was negative in all pts. At the time of the last follow-up, 21 pts were alive and 79 pts had died. Median OS was 1.3 (0.4-2.3) years in pts with membranous beta-catenin expression <= 75% and 1.7 (1.3-2.1) years in pts with membranous beta-catenin expression >75% (p=0.045). Median OS was (1.3-2.0) 1.6 years in pts with cytoplasmic beta-catenin expression <= 25% and 0.9 (0.5-1.2) years in pts with cytoplasmic beta-catenin expression >25% (p=0.040). In the univariate Cox proportional hazard models HR (95% CI) was 0.556 (0.311-0.995) in pts with membranous beta-catenin expression >75% (p=0.048) and 2.200 (1.216-3.980) in pts with cytoplasmic beta-catenin expression >25% (p=0.009). The present results indicate a favorable prognostic significance of membranous beta-catenin expression in pancreatic cancer. |
