ABSTRACT

Objective:

To investigate the correlation between CD133 expression and clinicopathological features in triple negative breast cancer (TNBC) patients, and the impact of CD133 on prognosis in these patients.

Methods:

Data of 70 patients who received surgical treatment in our center from Jan. 2008 to Dec. 2012 were collected. Immunohistochemistry was used to examine the expression of CD133. Patients were divided into two groups according to CD133 expression. Univariate analysis, Cox and Logistic regression multivariate analysis were used in order to investigate the correlation between CD133 expression and clinicopathological features. Kaplan-Meier curve and Log-rank analysis were used to evaluate DFS (disease-free survival) and OS (overall survival) .

Results:

CD133 was expressed in cytomembrane and cytoplasm with expression rate of 95.71% (67/70) . Of which, 64.29% (45/70) of patients were low CD133 expression and 35.71% (25/70) were high expression. High CD133 expression was significantly correlated with younger age (≤50) ( P=0.007) and larger tumor size (>2 cm) ( P=0.020) . Tumor size ( P=0.035) , axillary status ( P=0.001) , Ki67 ( P=0.005) and CD133 expression ( P=0.014) were independent predictors of recurrence and metastasis in TNBC patients. Axillary status was independent predictor of death event ( P=0.008) . Increased CD133 was associated with poor prognosis. Compared with high expression, patients with low CD133 expression had better DFS ( P=0.002) and OS ( P=0.088) , while OS did not reach significant difference.

Conclusion:

CD133 expression was correlated with age and tumor size in TNBC patients. High expression was associated with recurrence, metastasis and poor prognosis. Thus, CD133 may be a potential biomarker in predicting prognosis in TNBC.
