ABSTRACT
Objective To study the expression of cyclin E and epidermal growth factor receptor (EGFR) in breast carcinoma and their correlation with metastasis,relapse and survival time. [WT5”HZ]Methods Cyclin E and EGFR expressions at protein level were determined by immunohistochemistry technique in 110 patients with breast carcinoma. Results Of the 110 patients,cyclin E and EGFR positive expression were both in 60 (54.55%),and there was a positive relationship between cyclin E and EGFR expression (r s=0.823,P =0.001);Cyclin E and EGFR expression level were correlated with clinical stage (? 2=12.86,P =0.005;? 2=14.21,P =0.004),tumor histological grading (? 2=8.86,P =0.005;? 2=4.90,P =0.04),lymph node metastasis (? 2=10.22,P =0.001;? 2=9.62,P =0.002),ER expression (? 2=29.8,P =0.001;? 2=32.08,P =0.001) and PR expression (? 2=19.56,P =0.001;? 2=26.92,P =0.001). The rate of local relapse and distant metastasis in cases with positive cyclin E and EGFR expression were significantly higher than that in cases with negative expression (? 2=7.33,P =0.01;? 2=7.88,P =0.005);The mean survival time and 5-year survival rate in cases with positive cyclin E and EGFR was significantly shorter than that in cases with negative expression. [WT5”HZ]ConclusionCyclin E and EGFR expression can predict the relapse and metastasis of breast carcinoma. They can be used as markers of prognosis of breast carcinoma in clinical practice.
