title: Centralisation of services for gynaecological cancers - a Cochrane systematic review.
abstract: OBJECTIVE
  Gynaecological cancers are the second most common cancers among women. It has been suggested that centralised care improves outcomes but consensus is lacking. This systematic review assesses the effectiveness of centralisation of care for patients with gynaecological cancer, in particular, survival advantage.
  
  
  METHODS
  A comprehensive search of the Cochrane Gynaecological Cancer Group Trials Register, CENTRAL (The Cochrane Library, Issue 4, 2010), MEDLINE, and EMBASE up to November 2010 was conducted. Registers of clinical trials, abstracts of scientific meetings, and reference lists of included studies were also searched. Randomised controlled trials (RCTs), quasi-RCTs, controlled before-and-after studies, interrupted time series studies, and observational studies were included and multivariable analysis to adjust for baseline case mix were used.
  
  
  RESULTS
  Five retrospective observational studies met the inclusion criteria. Meta-analysis of three studies assessing over 9000 women suggested that institutions with gynaecologic oncologists on site may prolong survival in women with ovarian cancer, compared to community or general hospitals: hazard ratio (HR) of death was 0.90 (95% confidence interval (CI) 0.82 to 0.99). Similarly, another meta-analysis of three studies assessing over 50,000 women, found that teaching centres or regional cancer centres may prolong survival in women with any gynaecological cancer compared to community or general hospitals (HR 0.91; 95% CI 0.84 to 0.99). The largest of these studies included all gynaecological malignancies and assessed 48,981 women, so the findings extend beyond ovarian cancer. One study compared community hospitals with semi-specialised gynaecologists versus general hospitals and reported non-significantly better disease-specific survival in women with ovarian cancer (HR 0.89; 95% CI 0.78 to 1.01). The findings of included studies were highly consistent.
  
  
  CONCLUSIONS
  The meta-analysis provides evidence to suggest that women with gynaecological cancer who received treatment in specialised centres had longer survival than those managed elsewhere.
