Aim:
The aim of the present study was to investigate the impact of cyclin E expression on cancer-specific survival, as well as on conventional clinocopathological and prognostic factors in endometrial endometrioid adenocarcinoma.
Materials And Methods:
The study consisted of 211 patients surgically treated for endometrial endometrioid adenocarcinoma at the Oulu University Hospital between 1992-2000. Tissue samples were immunohistochemically stained for cyclin E and clinicopathological data were retrospectively retrieved from the patients' records.
Results:
Cyclin E expression correlated with grade but not with the Fédération Internationale de Gynécologie Obstétrique (FIGO) stage or myometrial invasion. Univariate and multivariate survival analyses were performed between patients grouped according to a receiver operating characteristic (ROC) curve-derived cut-off value. A statistically significant difference in survival was demonstrated between patient groups in Kaplan-Meier analysis.
Conclusion:
Contrary to previous literature, we found a correlation between cyclin E expression and prognosis. Further large-scale studies are required to confirm our findings.

M-Cdk Drives Transition Into Mitosis
Cyclin-dependent kinases, or Cdks, work in concert with cyclins to control cell cycle transitions. M-Cdk, a complex of Cdk1 bound to M cyclin, is a well-known example of this coordinated control that drives the transition from the G2 to the M phase.
