Measurement of soluble (s) P-selectin levels has been proposed as a diagnostic tool for monitoring the clinical course of human neoplasms. Thus, our study was aimed at analyzing the role of sP-selectin in association with clinicopathological variables in 181 patients with primary (n=149) or metastatic (n=32) colorectal cancer (CRC), 34 patients with benign diseases and 181 control subjects. The results obtained showed that sP-selectin levels were higher in patients with CRC compared either to patients with benign disease (p=0.006) or controls (p=0.003). No differences were observed between the latter and patients with benign diseases. Increased median sP-selectin levels were significantly associated with the presence of distant metastasis (68.2 ng/ml vs. 48.6 ng/ml, p=0.002). Of interest, carcinoembryonic antigen (CEA) levels were independently associated to sP-selectin (regression coefficient=0.28, p<0.002). Cox's proportional hazards survival analysis of primary CRC patients demonstrated that beside the stage of disease sP-selectin levels had an independent prognostic role in predicting recurrent disease (HR=2.22, p=0.019) and mortality from CRC (HR=3.44, p=0.017). These results suggest that measurement of plasma sP-selectin might represent a prognostic indicator in the management of patients with CRC. (C) 2004 Wiley-Liss, Inc.

Abstract
Measurement of soluble (s) P-selectin levels has been proposed as a diagnostic tool for monitoring the clinical course of human neoplasms. Thus, our study was aimed at analyzing the role of sP-selectin in association with clinicopathological variables in 181 patients with primary (n=149) or metastatic (n=32) colorectal cancer (CRC), 34 patients with benign diseases and 181 control subjects. The results obtained showed that sP-selectin levels were higher in patients with CRC compared either to patients with benign disease (p=0.006) or controls (p=0.003). No differences were observed between the latter and patients with benign diseases. Increased median sP-selectin levels were significantly associated with the presence of distant metastasis (68.2 ng/ml vs. 48.6 ng/ml, p=0.002). Of interest, carcinoembryonic antigen (CEA) levels were independently associated to sP-selectin (regression coefficient=0.28, p<0.002). Cox's proportional hazards survival analysis of primary CRC patients demonstrated that beside the stage of disease sP-selectin levels had an independent prognostic role in predicting recurrent disease (HR=2.22, p=0.019) and mortality from CRC (HR=3.44, p=0.017). These results suggest that measurement of plasma sP-selectin might represent a prognostic indicator in the management of patients with CRC.
