e16554 Background: To explore the expression pattern and clinical significance of the CLU and proliferation indices ki67 in cervical cancer. Methods: 59 cases treated at Cancer Center Sun Yat-sen University during 1989–2006 were enrolled in the study group. The relationship was analyzed for the expressions of CLU and Ki67 with clinical factors. Results: In this study positivity of CLU in cervical SCC, 10% (3/31) cases weak positive, adenocarcinoma 21% (4/19) weak positive in small cell carcinoma 11% (1/9) moderate positive. Control groups, CLU weak positive expression, 21% (3/14) CIN 2–3 and 14% (2/13) normal squamous epithelium.CLU expression found 100% (31/31) normal endocervical glands.The Ki67 in SCC 13% (4/31) cases weak positive and 5% (1/19) adenocarcinoma. All cases small cell carcinoma revealed negative. No significant difference of the CLU expression rate between normal cervical epithelium, CIN II-III and SCC (p = 0.561). No significant difference of CLU expression rate between normal endocervical gland and adenocarcinoma (p = 0.119) as well. In Ki67, there was no significant difference of Ki67 rates between CIN 2–3 and normal squamous epithelium (p = 0.585). No significant difference of Ki67 expression rates between adenocarcinoma and normal squamous epithelium (p = 0.341). The expression of CLU and Ki67 had no correlation with FIGO stage, SCC antigen level, grade of differentiation, deep stromal invasion, and lymph node metastasis. Finally, the expression of CLU and Ki67 was not related to the 5-years DFS rates, and CLU expression was not correlated with Ki67 expression (rs = 0.500, p = 0.391). Conclusions: CLU and Ki67 was in lower rates in cervical cancer, and was not associated with any clinicopathological features. It is suggested that CLU and Ki67 have no distinct role in carcinogenesis. The further larger studies are needed to verify the results of this study. No significant financial relationships to disclose.
