- Abstract
Objective. We aimed to evaluate prognostic factors impacting on overall survival during a 20 year period with substantial changes in surgical approach and chemotherapy management of patients with epithelial ovarian carcinoma stage IV. Design. A retrospective population-based study. Setting. The Norwegian Radium Hospital during 1985-2005. Population. Three hundred and ninety-four patients with epithelial ovarian carcinoma stage IV treated at the Norwegian Radium Hospital. Methods. The cohort was divided into two groups (1985-1995 and 1996-2005), and clinical and pathological characteristics were compared. Univariate and multivariate analyses were performed to identify prognostic factors during 1985-1995, 1996-2005 and 1985-2005. Main outcome measures. Prognostic factors and overall survival in the three periods. Results. Median overall survival improved from 1985-1995 to 1996-2005 (from 1.3 to 2.1 years). More patients had macroscopic radical surgery (28 vs. 11%), received neoadjuvant chemotherapy and were treated with platinum-taxane combination therapy from 1996-2005 compared to 1985-1995. Patients with primary surgery had improved median overall survival from 1996-2005 compared to 1985-1995. In multivariate analyses, surgical approach was not a prognostic factor for overall survival, but chemotherapy was during 1985-2005. Postoperative residual tumor was a prognostic factor for overall survival in all periods. Conclusions. Macroscopic radical surgery is a strong prognostic factor for overall survival and is achievable in a subset of patients with epithelial ovarian carcinoma stage IV. Improved selection criteria for what treatment algorithm to choose for patients with epithelial ovarian carcinoma stage IV are warranted.
