Biomarkers for the diagnosis, prognosis, and targeting therapy of gallbladder cancers are not clinically available. This study demonstrated that the percentage of cases with positive SHP2 and UGP2 expression significantly correlated with the percentage of cases with positive vimentin, β-catenin, MMP2, MMP9, and Ki-67 expression, large tumor size, high TNM stage, lymph node metastasis, and survival in patients with adenocarcinomas and squamous cell/adenosquamous carcinomas. Positive SHP2 and UGP2 expression are independent poor-prognostic factors in both types of tumors. Our study suggested that positive SHP2 and UGP2 expression correlated with clinicopathological and biological behaviors, and poor-prognosis of gallbladder cancer. [ABSTRACT FROM PUBLISHER]

Cofilin-1 (CFL1) and Arp3 expression in 46 squamous cell and adenosquamous carcinomas (SC/ASCs) and 80 adenocarcinomas (ACs) were measured by using immunohistochemistry. Positive CFL1 and Arp3 expression were significantly associated with large tumor size, high TNM stage, lymph node metastasis, and decreased overall survival in both SC/ASC and AC patients ( p < .001). Multivariate Cox regression analysis showed that positive CFL1 and Arp3 expression are independent poor-prognostic factors for both SC/ASC and AC patients. Our study suggested that positive CFL1 and Arp3 expression are closely related to tumor progression, metastasis, and poor prognosis of gallbladder cancer. [ABSTRACT FROM AUTHOR]
