Abstract
AIM: To detect the expression of c-Cbl and Cbl-b in gastric cancer and to analyze their clinical significance.
METHODS: One hundred gastric cancer surgical resection specimens collected between January 2012 and December 2014 were included in an observation group, and 20 adjacent normal gastric tissues were included in a control group. The two groups of specimens were used for preparation of tissue chip. The expression of c-Cbl and Cbl-b was detected by immunohistochemical method, and the relationship between c-Cbl and Cbl-b expression and clinical and pathological features of gastric cancer was analyzed.
RESULTS: The positive rates of c-Cbl and Cbl-b in the observation group were 72% and 83%, respectively, which were significantly higher than those in the control group (20% and 25%, respectively). c-Cbl expression had a significant positive correlation with tumor stage and depth of invasion. The expression of Cbl-b was significantly positively correlated with tumor stage and lymph node metastasis. c-Cbl expression was positively correlated with Cbl-b expression in gastric cancer (P < 0.05). There were 29 cases of specimens that were strongly positive for both proteins, and the clinical and pathological characteristics of these patients were mainly late stage, increased number of metastatic lymph nodes, deep tumor infiltration and poor differentiation.
CONCLUSION: The expression of c-Cbl and Cbl-b increases in the development and invasion of gastric cancer, and the detection of c-Cbl and Cbl-b expression has clinical significance and value for clinical diagnosis of gastric cancer.
