- Abstract
- The role of beta-catenin and Dickkopf-1 (DKK1) is dependent on the specific immunobiology of T cell inflammation in biliary tract cancer (BTC). We aimed to analyze the role of DKK1 or beta-catenin as a prognostic factor in BTC, and determine the clinical associations of ss-catenin and DKK1 with CD8+ tumor-infiltrating lymphocytes (TIL). We used data from The Cancer Genome Atlas Research Network and the clinicopathological data of 145 patients with BTC who had undergone primary radical resection between 2006 and 2016. CD8+ TIL expression was a significant predictor of favorable overall survival (OS) and relapse-free survival (RFS) (median OS, 34.9 months in high-TIL, 16.7 months in low-TIL, P < 0.0001 respectively; median RFS, 27.1 months in high-TIL, 10.0 months in low-TIL, P < 0.0001 respectively). In the high-CD8+ TIL BTC group, the tumor expression of beta-catenin and DKK1 had a significant negative impact on either OS or RFS. In the low-TIL BTC group, there were no differences according to ss-catenin and DKK1 expression. Cox regression multivariate analysis demonstrated that CD8+ TIL and beta-catenin retained significant association with OS. Among patients with resected BTC, the beta-catenin and DKK1 protein and high CD8+ TIL levels were associated with poor and good clinical outcomes, respectively.
