Background:
The prognostic value of D-dimers concentration in portal blood in patients with pancreatic cancer has been established in several studies. Thyroid hormones and their receptors, especially T3 also seems to have a specific role in process of neoplasia and metastatic spread.
Objective:
The aim of the study was to look for changes of thyroid hormones concentration between portal and peripheral blood.
Methods:
We included prospectively 8 patients with pancreatic cancer, without liver dysfunction, qualified to surgical treatment. D-dimers, THS, fT3, fT4 concentration was determined in blood samples from portal and peripheral vein taken intraoperatively.
Results:
The difference and quotient of portal and peripheral concentration of D-dimers, THS, fT3 and fT4 was calculated (D-dimer-; THS-; fT3-; fT4-d and -q). The level of D-dimers measured in portal blood was > 2700 ng/mL in 3 patients. The peripheral fT3 level was significantly higher In high portal D-dimers group. FT3 change coefficients showed strong statistically significant negative correlation with portal D-dimer concentration level.
Conclusions:
We suggest that fT3 or its receptors can influence progression of pancreatic malignancies. The results of this study are also a new evidence that both fT3 and portal D-dimers are biologically linked to intensity of local neoplastic process. Nevertheless, deeper knowledge about portal circulation probably constitute missing part in understanding nature of pancreatic neoplasia. Investigations both on larger group and in the field of basic sciences are needed.
