Overview
Introduction:
Pancreatic cancer (PDAC) is one of the most aggressive malignancies. Its incidence increases worldwide and, despite the developments in cancer research, mortality rates have not decreased. Poor prognosis of the disease is due to many factors, mainly late diagnosis. Distant metastases and peritoneal carcinomatosis are caused by hematogenous and lymphogenous spreading of the tumorous cells. One of the factors that may influence patient survival are so-called circulating tumor cells (CTCs). The aim of our work was to evaluate the possible influence of CTCs on the survival of patients with PDAC.
Method:
We included patients who underwent a radical or palliative surgical intervention at the First Department of Surgery of Medical Faculty and University Hospital in Olomouc between 1 January 2008 and 31 December 2012. The required samples for CTCs detection were taken from each patient. The detection of the CTCs was performed using real-time RT-PCR. The results were statistically processed and evaluated.
Results:
We included 126 patients in total, of which 88 were treated radically and 38 received palliative treatment. Mean age was 63 years in patients with radical and 64 years in patients with palliative surgery. Mean survival time in radically treated patients was 29.6 months, in patients with palliative treatment the mean survival time was 8.5 months. The survival time of radically treated patients with CTCs was 27.2 months, without CTCs it was 33.8 months.
Conclusion:
We did not prove a statistically significant difference in survival between radically treated PDAC patients with and without detected CTCs in our work.
Key words:
pancreatic cancer – circulating tumor cells − survival
