ABSTRACT
Objective@#To observe the expression and clinical significance of galectin-1 in Chinese laryngeal squamous cell carcinoma patients.@*Methods@#Immunohistochemical technique was used to test the galecin-1 protein expression in the 50 laryngeal squamous cell carcinoma patients and Western blot method was used to test the galecin-1 protein expression in the 3 of the patients. SAS 9.4 software was used to analyze the relationship between the galectin-1 protein and the clinical degrees, pathological grades and lymph node metastasis in all the cases.@*Results@#In the 50 laryngeal squamous cell carcinoma patients, the positive rate of galectin-1 protein was 74% (37/50). The expression of galectin-1 protein was correlated with the severity of clinical staging, pathological differentiation and lymph node metastasis.@*Conclusions@#High expression of galectin protein related with the occurrence and development of head and neck squamous cell carcinomas.
