Trefoil factor family protein 1 (
TFF1
,
pS2
) interacts with mucins to protect gastrointestinal epithelium against injury and contributes to mucosal repair by promoting epithelial cell migration and restitution. Moreover,
TFF1
has antiproliferative and anti-apoptotic effects and promotes cell scattering and invasion. We investigated
TFF1
expression in healthy and inflamed non-neoplastic gallbladder mucosa as well as in gallbladder carcinomas (n=57) and corresponding metastases (n=18), using a tissue microarray technique.
TFF1
immunoreactivity was absent in healthy mucosa, focally observed in epithelium with inflammatory changes and present in 35% of primary and 24% of metastatic cancer tissues. Immunoreactivity significantly decreased with increasing tumour stage (P=0.009) and increasing tumour grade (P=0.001). Patients with
TFF1
positive tumours showed a more favourable outcome compared to patients with
TFF1
negative tumours in univariate analysis (P=0.006). However, multivariate analysis proved resection status and tumour grade as the only independent prognostic factors. In conclusion,
TFF1
is expressed in inflamed non-neoplastic gallbladder epithelium and in low stage and low grade gallbladder carcinomas. Thus,
TFF1
may be the missing link between gallstones,
chronic cholecystitis
and gallbladder cancer. Further studies are needed to evaluate whether
TFF1
immunostaining can be used as a diagnostic tool to identify patients with a more favourable outcome.
