title: CCND1 G870A polymorphism and cervical cancer risk: a case-control study and meta-analysis.
abstract: OBJECTIVE
  Cyclin D1 (CCND1) is a key regulatory protein in the G1/S checkpoint of the cell cycle. We hypothesized that the G870A polymorphism of CCND1 is associated with the risk for cervical cancer and performed a meta-analysis of eligible studies to evaluate this relationship.
  
  
  METHODS
  In a case-control study of 300 patients with newly diagnosed cervical cancer and 312 cancer-free controls who were frequency-matched by age, we genotyped the G870A polymorphism of CCND1 by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). A meta-analysis was performed using five case-control studies, including our results.
  
  
  RESULTS
  No significant association was observed between the G870A polymorphism of CCND1 and cervical cancer risk. Further, in our meta-analysis, there was no significant risk of cervical cancer that correlated with the G870A polymorphism of CCND1. In the stratified analysis by race, however, individuals who harbored the AA or AA/AG genotypes were at significantly greater risk compared with GG carriers in the Asian population.
  
  
  CONCLUSIONS
  The G870A polymorphism in CCND1 may not contribute to the etiology of cervical cancer in Chinese populations.
