Abstract:

BACKGROUND: With the deepening of tumor stem cell research, lung cancer stem cells have become one of the research hotspots.
OBJECTIVE: To evaluate the expression of tumor stem cell marker CD133 in lung cancer tissues, and to evaluate the correlation with the clinicopathologic characteristics of lung cancer.
METHODS: Immunohistochemical staining was used to detect the positive expression rate of CD133 in lung cancer tissues with different types and differentiation degrees, as well as to analyze the correlation between CD133 positive expression and the clinicopathologic characteristics, including the age, gender,   
size of the tumor, histological type, stage and grade, degree of differentiation, lymphatic metastasis and prognosis.
RESULTS AND CONCLUSION: CD133 had higher positive expression rate in various types of lung cancer tissues, but the positive expression rate had correlation neither with the clinical characteristics of the patients including age and gender, nor with the histological type, stage and grade and the degree of differentiation. The positive expression rate was closely related with lymphatic metastasis and prognosis. The positive expression rate of CD133 was higher in the lung cancer tissues with lymphatic metastasis, and 5-year survival rate was significantly lower with poor prognosis.
