| Research Abstract |
Pancreatic cancer still remains one of the most lethal diseases with increasing incidence. We recently identified Apolipoprotein C-1 (ApoC-1) as the serum biomarker for pancreatic cancer by serum protein profiling using surface-enhanced laser desorption ionization time-of-flight mass spectrometry (SELDI-TOF MS). The purpose of this study is to confirm whether serum ApoC-1 levels of patients with pancreatic cancer were a valuable marker using convenient ELISA method, and also whether ApoC-1 expression in resected pancreatic cancer tissue correlates with prognosis of patients after surgery.
We analyzed ApoC-1 serum level of 32 patients by two proteomic approaches. We also investigate whether ApoC-1 positive expression in resected tissues of patients with pancreatic cancer showed meaningful results in clinical outcome.
ApoC-1 serum levels were significantly decreased in compared preoperative and postoperative serum of patients both SELDI analysis and ELISA method. ApoC-1 levels of pancreatic cancer patients are significantly higher than that of patients with benign pancreatic disease by ELISA method. Furthermore, the immunohistochemical staining of ApoC-1 indicated that overexpression of ApoC-1 in resected pancreatic cancer tissues showed poor prognosis of patients (log rank-test ; P<0.038).
These results suggested that ApoC-1 positive expression was possible to predict poor prognosis of pancreatic cancer patients after surgery.
