Abstract

Platelet-derived growth factor (PDGF)-C and PDGF-D are frequently upregulated in human cancers and play important roles in tumor progression, angiogenesis and metastasis. However, the distribution, frequency and prognostic value of PDGF‑C and PDGF‑D expression in gastric cancer have not been clarified. The present study evaluated the association between expression of PDGF‑C and PDGF‑D, clinicopathological factors and outcomes, in patients with gastric cancer. Gastric adenocarcinoma tumor samples were obtained from 204 patients who underwent curative gastrectomy between 2003 and 2007. The expression of PDGF‑C and PDGF‑D was analyzed by immunohistochemical staining. High expression of PDGF‑C and PDGF‑D was detected in 114 (56%) and 151 (74%) tumors, respectively. PDGF‑D expression was significantly associated with tumor depth (P=0.039), histopathology (P<0.01), tumor stage (P=0.01) and recurrence (P<0.01), whereas PDGF‑C expression correlated only with histopathology (P=0.05). High PDGF‑D expression was also associated with significantly shorter relapse‑free survival (RFS) time (P<0.01), whilst high PDGF‑C expression was associated with marginally, but not significantly, shorter RFS (P=0.10). On multivariate analysis, high PDGF‑D expression was determined to be an independent prognostic factor (hazard ratio, 3.3; 95% confidence interval, 1.20‑9.4; P=0.02). These findings indicate that high PDGF‑D expression is strongly associated with tumor progression, recurrence, distant metastasis and poor outcomes in patients with gastric cancer. PDGF‑D may therefore be an independent prognostic factor and a novel therapeutic target.
