Abstract

Overall survival remains unsatisfactory in stage II/III gastric cancer, even after curative surgery and adjuvant chemotherapy. Platelet‑derived growth factor receptor‑β (PDGFR‑β) is associated with the proliferation of cancer cells. The present study therefore investigated the association of PDGFR‑β gene expression with patient outcome in 134 stage II/III gastric cancer patients who received adjuvant chemotherapy with S‑1. Relative PDGFR‑β gene expression was measured in surgical cancer tissue and adjacent normal mucosa specimens by reverse transcription‑quantitative polymerase chain reaction. The PDGFR‑β gene expression levels were found to be significantly higher in the cancer tissues compared with the adjacent normal mucosa. A high level of PDGFR‑β gene expression was associated with a significantly poorer 5‑year overall survival rate compared with a low level of PDGFR‑β expression. Upon multivariate analysis, PDGFR‑β gene expression was found to be an independent predictor of survival. Overall, the study indicates that PDGFR‑β overexpression in gastric cancer tissues is a useful independent predictor of outcome in patients with stage II/III gastric cancer who receive adjuvant chemotherapy with S‑1.
