The results of treatment of epithelial ovarian cancer after centralisation of primary surgery. Results from North Jutland, Denmark

Abstract

Objective. The study was performed to evaluate the results of treatment of ovarian carcinoma after the introduction of centralised primary surgery in the County of North Jutland, Denmark. Method. Prospective study of consecutive cases of ovarian cancer undergoing primary surgical treatment at the Gynecologic Oncologic Center after the introduction of centralised primary surgery. Results of treatment recorded up to the date of last examination or death. Results. From 1999 to 2002, 107 patients with primary epithelial ovarian cancer underwent primary surgery at the Gynecologic Oncologic Center, Aalborg. This corresponds to 95.5% of patients with invasive carcinoma in the County of North Jutland. All patients with Stage I to Stage IIIB disease had a complete, macroscopically radical cytoreduction performed. In patients with Stage III and IV invasive tumors, the optimal debulking rate was 79.5%, and, in Stage IIIC and IV, the optimal debulking rate was 78.2%. Intra-operative and post-operative complications were generally few. Post-operative death, defined as death within 30 days after surgery, was observed in 4 cases (3.7%). After primary surgery, platinum-based chemotherapy was given in most cases. For Stage I to IV invasive cancer, the median survival was 46 months. In patients with Stage IIIC and IV disease, the median survival was 32 months. In optimally debulked Stage IIIC and IV disease, the median survival was 41 months. Conclusions. The results indicate a survival benefit after introduction of centralised primary surgery. Compared to existing national and regional data on survival in ovarian cancer, the results indicate an increase in median survival for all stages of approximately 15 months. Centralisation of primary surgery to centres with the necessary expertise may be the most significant way to increase survival in ovarian cancer in Denmark.
