The analysis on Tiam2 for expression in esophageal carcinoma: A descriptive study

Rationale: To investigate T lymphoma invasion and metastasis inducing factor 2 (Tiam2) protein for expression in esophageal carcinoma and relationship with clinical features among cases with tumors. Patient concerns: In primary esophageal cancer patients, surgical resection of tumor tissue was performed in 65 cases and adjacent normal esophageal tissue in 20 cases. Diagnoses: Primary esophageal carcinoma (57 cases squamous cell carcinoma, 8 cases adenosquamous carcinoma). Interventions: The expression level of Tiam2 protein in esophageal carcinoma tissues and normal esophageal tissues by SP immunohistochemical method. The expression intensity was quantitatively analyzed by using Image-pro plus software for image analysis, while SPSS26.0 software was used for a statistical analysis on the data. Outcomes: Tiam2 was highly expressed in esophageal squamous cell carcinoma and adenosquamous cell carcinoma, but low expressed in normal esophageal tissue. The expression level of Tiam2 protein was not correlated with gender and age of patients (P > .05), but was correlated with lymph node metastasis of esophageal carcinoma, TNM stage and differentiation degree of esophageal squamous cell carcinoma (P < .05). Tiam2 was positively correlated with Tiam1 for protein expression in esophageal carcinoma (r = .704, P < .001). Lessons: The increased expression of Tiam2 protein in esophageal cancer may be an early molecular event of esophageal cancer. Tiam2 protein has a high expression level in esophageal carcinoma related to lymph node metastasis, TNM stage and differentiation degree, which suggests that Tiam2 protein plays an important role in the invasion and metastasis of esophageal carcinoma. There is a positive correlation between Tiam2 and Tiam1 protein expressions in esophageal carcinoma, suggesting that the 2 proteins may have a definite internal relationship.
