Purpose:
Pancreatic cancer is a highly aggressive malignant tumour with poor prognosis. The median survival is only 6 months. This study investigated the prognostic value of nuclear export protein chromosomal region maintenance/exportin 1/Xpo1 (CRM1) expression in pancreas cancer.
Methods:
CRM1 expression was detected, by Western blot, in pancreatic tissue from 69 cancer patients and 10 normal subjects.
Results:
CRM1 showed increased expression in pancreatic cancer tissue (P = 0.007). The high expression of CRM1 was associated with increased serum levels of CEA (P = 0.002) and CA19-9 (P = 0.005). There was an association between CRM1 expression and tumour size (P = 0.01), lymphadenopathy (P = 0.004) and liver metastasis (P = 0.003). High CRM1 expression was not correlated with the other clinicopathological parameters. High CRM1 expression was a prognostic indicator for progression-free survival (PFS) (P = 0.006) as well as overall survival (OS) (P = 0.001). Expression of CRM1 was an independent prognostic parameter for poorer PFS and OS (95% CI, 1.27-5.39).
Conclusions:
CRM1 expression demonstrated prognostic value in pancreatic cancer. Prospective studies are required to determine the prognostic role of high expression of CRM1 in pancreatic cancer.
