The Comparison of Pre-diagnostic and Diagnostic Thrombocyte Levels in Pancreatic and Biliary Tract Cancers

Abstract Aim The role of thrombocytes in tumor growth and metastatic spread was defined after the discovery of tumor fragments disseminated with thrombi brake off and embolization in distant body sites. Most cancers reported being related with thrombocytosis. In this study, we try to evaluate the variation of thrombocyte levels of biliary and pancreatic cancers in time to diagnosis. Material And Methods The patient records of Afyonkarahisar Health Sciences University Department of Medical Oncology between 2012 and 2018 were retrospectively analyzed. The patients who have 6 months or prior CBC before the diagnosis included in the study. Results A total number of 42 patients included in the study which was composed by 17 pancreatic, 17 biliary tract and 8 gallbladder adenocarcinomas after the complete evaluation of medical records. The mean (median) thrombocyte levels were 239000 (230000) and 260000 (251000) in pre-diagnostic and diagnostic groups respectively. The mean time between the prior blood test and diagnosis were 15.9 months. There was a statistically non-significant difference between pre-diagnostic and diagnostic thrombocyte levels. (p=0.08) The correlation was positive which determines thrombocyte levels increase with the time to diagnosis. When the thrombocyte levels categorized with the cut-off 400000 in the time of diagnosis and before diagnosis, there is a significant difference between groups. (p=0.04) Conclusion In this study, we found an elevation in the thrombocyte levels through the diagnosis of pancreaticobiliary tumors. The thrombocyte levels may be an indicator for this condition, but the alteration in normal ranges through the diagnosis makes it an unpractical marker.
