Abstract:
Objective To analyze the expression and clinical significance of PIK 3CA protein in squamous cell carcinoma of the esophagus .Methods Forty -five samples of surgical resection of esophageal squamous cell carcinoma were collected as the observation group ,and 45 normal tissues adjacent to the carcinoma were selected as the control group.The expression of PIK3CA protein in the tissues of esophageal squamous cell carcinoma and the corresponding para cancerous tissue was detected by immunohistochemistry ( IHC).Results The results of IHC showed that the positive expression rate of PIK 3CA protein in esophageal squamous cell carcinoma was 53.33%, which in adjacent normal tissues was 0.00%,the difference was statistically significant (χ2 =32.727,P<0.01).The positive expression rate of PIK3CA protein was correlated with lymph node metastasis ,differentiation and clinical stage of esophageal squamous cell carcinoma (χ2 =5.180,8.201,13.566,P=0.023,0.017,0.001),and was not correlated with the degree of tumor invasion (χ2 =0.952,P =0.329).Conclusion The expression of PIK3CA protein is abnormal in esophageal squamous cell carcinoma ,and the expression of PIK3CA protein plays a role in the occurrence and development of esophageal squamous cell carcinoma .
