Down-regulation of EGFL8: a novel biomarker for advanced gastric cancer.

Anticancer Research 2011 October
BACKGROUND: Recently, we have reported an important role of epidermal growth factor-like domain 8 (EGFL8) in the progression of colorectal cancer (CRC) and documented EGFL8 to be a novel prognostic biomarker for this malignancy. However, the function of EGFL8 in the other human gastroenterological malignancies such as gastric cancer remains largely unknown.

PATIENTS AND METHODS: EGFL8 expression in 53 cases of gastric cancer and the corresponding normal tissues were determined by quantitative real-time PCR and the EGFL8 down-regulation score for each patient was calculated. Subsequently, the correlations between EGFL8 down-regulation score and the clinicopathological features of gastric cancer were evaluated.

RESULTS: EGFL8 expression was significantly lower in the gastric cancer tissues than the corresponding normal tissues (p=0.0001) and the down-regulation of EGFL8 was evident in 73.6% (39/53) of the gastric carcinomas. More importantly, EGFL8 down-regulation was correlated significantly with peritoneal dissemination (p=0.037) and high TNM stage (p=0.025) of gastric cancer.

CONCLUSION: The down-regulation of EGFL8 might be a novel biomarker for advanced gastric cancer.
