EXPRESSION OF c-erbB-2 AND PCNA IN CERVICAL ADENOCARCINOMA AND ITS SIGNIFICATION

摘要

Objective: To investigate the significance of cerbB-2 and PCNA expression in adenocarcinoma.Methods: Expression of c-erbB-2 and PCNA in 74 cases of adenocarcinoma of the uterine cervix was examined by immunohistochemistry. Results: The expression of cerbB-2 was detected in 34 cases. The positive staining of c-erbB-2 was associated with increased lymph node metastasis (57.1% Vs 24.0%, P=0.041) and lower 5-year survival rate (32.4% Vs 58.9%, P=0.008). The average PCNA labeling index (PCNA LI) was 40.6% (0.1%-91.4%). High PCNA LI was associated with lymph node metastasis (56.4% Vs 38.5%, P=0.016) and lower 5-year survival rate (28.7% Vs 64.4%, P=0.005). Positive staining of c-erbB-2 were associated with high PCNA LI(44.7% Vs 34.6% P=0.003). Conclusions: c-erbB-2 and PCNA LI were associated with malignant biological behavior and poor prognosis of patients with cervical adenocarcinoma.
