Abstract

Backgrounds/aims: Pancreatic cancer is one of the most fatal human malignancies with poor prognosis, despite advances in therapy. Here, we evaluated the potential role of collagen type VI α3 chain (COL6A3) as a non-invasive biomarker for pancreatic adenocarcinoma.

Methods: In this study, we investigated immunohistochemically the expression of COL6A3 in 30 patients with resectable pancreatic adenocarcinoma by immunohistochemistry in a tissue sample of the cancer and a tissue sample of normal pancreas for each patient. Also, we looked for associations between COL6A3 and other prognostic factors of pancreatic cancer.

Results: All of the pancreatic cancer tissue samples revealed in different ranges of intensity from weak (+) in 16.67%, moderate (+2) in 50%, to strongly positive (+3) in 33.33% staining for COL6A3. We found no moderate or strongly positive staining in normal pancreatic tissue. There was only weak positive staining in 23 samples (76.67%) and 7 (23.30%) were negative. Also, there was significant correlation between COL6A3 moderate and strongly expression and negative prognostic factors for pancreatic cancer.

Conclusions: The greatest density of COL6A3 was observed in pancreatic cancer tissues and was correlated with negative prognostic factors for pancreatic cancer. Therefore, we suggest that COL6A3 could be used as prognostic factor in pancreatic cancer, but more studies need to prove its value.

Keywords: COL6A3; Pancreatic adenocarcinoma; Prognosis.
