We aimed to investigate the relationship between blood groups and pancreatic cancer in a Turkish population in Western Blacksea region. Methods: This is a retrospective study. Zonguldak Karaelmas University outpatient oncology clinic records were screened for the period between 2004 and 2011. Results: The median age of patients were 56 (±16) and 132 of 633 study population had pancreatic cancer. Pancreatic cancer patients had significantly higher rates of blood group A compared to controls (OR

The median survival (IR) time in subjects having the blood groups A, B, AB and O were 7.0 (1-28), 7.0 (2-38), 10 (2-36) and 9.0 (2-48) months respectively; the blood group 0 had significantly higher overall survival (OS) compared to the non-0 groups (p 0.04). Conclusions: Pancreatic cancer patients had more common blood group A in our population. Moreover, blood group AB appeared to be a protective factor against pancreatic cancer in our population. Blood group 0 had a significantly longer survival compared to non-0, regardless of prognostic factors.
