| Abstract
Background: In cervical cancer patients it has been reported that there in a signifcant Ki-67/MIB-1 expression
is correlated with survival in cervical cancer patients. However, the prognostic value is still not well understood.
Materials and Methods: In the present meta-analysis the prognostic value of Ki-67/MIB-1 with regard to overall
survival (OS) and disease-free survival (DFS) in cervical cancer was investigated. The databases of PubMed, ISI
Web of Science, Cochrane Central Register of Controlled Trials, EMBASE, Science Direct and Wiley Online
Library were used to identify appropriate literature. Results: In order to explore the relationship between Ki-67/
MIB-1 and cervical cancer, we have included 13 studies covering 894 patients in the current meta-analysis. The
effect of Ki-67/MIB-1 on OS for pooled random effects HR estimate was 1.63 (95%confdence interval (CI) 1.09-
2.45; P<0.05). The pooled HR for DFS was 1.26 (95%CI 0.58-2.73; P>0.05) and the subgroup analysis indicated
Ki-67/MIB1 was associated with DFS (HR=3.67, 95%CI 2.65-5.09) in Asians. Conclusions: According to this
meta-analysis, Ki-67/MIB-1 has prognostic value for OS in patients suffering from cervical cancer. For better
evaluation of the prognostic role of Ki-67/MIB-1 on DFS, studies with larger numbers of patients are needed to
validate present fndings in the future. |
