Abstract
Background
Squamous cell/adenosquamous carcinoma (SC/ASC) is a rarely identified form of gallbladder cancer with poorly understood clinical features. As such, there is an urgent need to identify novel prognostic biomarkers for such gallbladder SC/ASC cases, and for gallbladder adenocarcinomas (ACs).
Methods
The levels of ACO2 and ANPEP proteins were assessed via an EnVision-based immunohistochemical approach using 46 SC/ASC and 80 AC patient samples.
Results
There was a marked reduction in levels of ACO2 and ANPEP in gallbladder AC relative to normal adjacent tissue or benign gallbladder lesions. The was a significant correlation between lack of ACO2 and ANPEP and larger tumors, higher tumor-node-metastasis (TNM) staging, invasion, metastasis to regional lymph nodes, and ineligibility for surgical resection in both SC/ASC and AC tumor samples. Kaplan–Meier survival analyses further confirmed a relationship between ACO2 and ANPEP negativity and decreased overall survival in patients with these diseases (p < 0.05 or p < 0.01), and a multivariate regression analysis further established that ACO2 negativity and ANPEP negativity were independently predictive of poor SC/ASC and AC patient outcomes.
Conclusions
ACO2 and ANPEP may have key physiological relevance in cancers of the gallbladder and thus warrant investigation as prognostic biomarkers.
