Quality Indicators and Survival Outcome in Stage IIIB-IVB Epithelial Ovarian Cancer Treated at a Single Institution

To investigate the overall survival rate, quality indicators and treatment outcome in FIGO stage IIIB-IVB epithelial ovarian cancer at a University Hospital in Sweden between 2006 and 2015. A cohort of 110 patients was followed-up for 3-12 years after cancer diagnosis. Three main groups (primary surgery, neoadjuvant chemotherapy, palliative treatment), and six subgroups were defined according to treatment modality. The mean age was 65 years. Patients were observed for a mean of 50 months. The total resection frequency was 83%. Significant differences in overall survival at 5 years were observed between the groups varying from 60% to 12%. Patient age, tumor stage and complete tumor removal at surgery were significant, independent prognostic factors of overall survival. Complication rate was a significant adverse prognostic factor in univariate analysis. Data discrepancy was observed between public quality reports and locally obtained data.
