Abstract
AIM: To examine the expression of WWOX and p53 proteins in gastric cancer, and to analyze the possible mechanisms behind the malignant growth of gastric cancer.
METHODS: The expression of WWOX and p53 proteins was detected by immunohistochemistry in 70 paraffin-embedded samples of gastric cancer and 20 tumor-adjacent normal tissue samples. Statistical analyses were then performed to analyze the relationship between WWOX and p53 expression and clinicopathologic parameters of gastric cancer.
RESULTS: The positive rate of expression of p53 protein in gastric cancer was significantly higher than that in normal gastric tissue (51.42% vs 0.00%, P < 0.05). Expression of p53 protein in gastric cancer was related with depth of invasion, lymph node metastasis, and tumor clinical stage (all P < 0.05). The positive rate of expression of WWOX protein was significantly lower in gastric cancer than in normal gastric tissue (41.43% vs 90.00%, P < 0.05). Expression of WWOX protein in gastric cancer was related with depth of invasion and clinical stage, but not with lymph node metastasis. There is a negative correlation between WWOX and p53 expression in gastric cancer.
CONCLUSION: Detection of expression of p53 protein and WWOX proteins might be useful for early diagnosis and evaluation of prognosis of gastric cancer.
