Abstract:
Objective Prostate cancer is one of the most common cancer in males .The article was to investigate the expres-sion and clinicopathological significance of VEGF-C mRNA in prostate cancer , finding the molecular marker for early diagnosis and prognosis assessment of prostate cancer . Methods TaqMan real-time polymerase chain reaction ( PCR) analysis was used to detect the expression of VEGF-C mRNA in 3 prostate cancer cell lines(PC-3, DU145 and LNCap), 32 cases of prostate cancer (Pca) sam-ples and 15 cases of benign prostatic hyperplasia (BPH).Analysis was also made on the correlations of VEGF-C mRNA expression, clinicopathological features and prognosis . Results High levels of VEGF-C mRNA were detected in PC-3 ( 153 .31 ±26 .24 ) and DU145(194.62 ±41.36)compared to LNcap(1.00 ±0.00).The expression of VEGF-C mRNA in prostate cancer tissues was 3.43 folds higher than that in the benign prostatic hyperplasia tissues ([13.67 ±1.95] vs [11.89 ±1.63], P=0.004).The high expres-sion of VEGF-C mRNA in prostate cancer was associated with high Gleason score ( P =0.004 ) and lymph node metastasis ( P =0.015).In patients with high expression and low expression of VEGF-C mRNA, the 3-year survival rate was 12.5%and 40.0%re-spectively(P=0.033). Conclusion The VEGF-C mRNA expression may be related to the biological behavior of prostate cancer .It is suggested that VEGF-C mRNA can be used as a prognostic marker for prostate cancer .
