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.
