Summary
Brief summary (as posted)
The purpose of this study is to determine, whether there is clinical benefit of using fdg-PET/CT (F-18-fluorodeoxyglucose- positron emission tomography/computed tomography)compared to contrast-enhanced CT in primary treatment of advanced epithelial ovarian cancer (EOC) * Objectives * the impact of preoperative PET/CT compared to CT on EOC stage definition * to compare the value of preoperative PET/CT, CT and laparoscopy in intra-abdominal tumour assessment. Laparotomy findings evaluated by surgeon and histopathologic results serve as the reference standard. * to compare serum markers HE4(human epididymis protein 4) and CA125 (cancer antigen 125) with FDG-PET/CT and CT in treatment response evaluation during neoadjuvant chemotherapy and primary treatment of EOC * to compare FDG PET/CT based treatment response evaluation with RECIST and GCIG criteria * Methods * All the patients will undergo FDG-PET/CT prior surgery, after possible neoadjuvant chemotherapy (NACT) and 4 weeks after completion of primary platinum-based chemotherapy. * CA125 and HE4 levels are measured pre-operatively, with every chemotherapy cycle and regularly during follow-up until 1st disease relapse

Arms (0)
[]Primary outcomes (1)
- measure
- PET/CT (positron emission tomography/computed tomography)compared with contrast-enhanced CT in preoperative evaluation of disease burden in patients with advanced Epithelial ovarian cancer (EOC).
- timeFrame
- PET/CT, contrast-enhanced CT and surgical status and histopathological findings are compared 1 month after surgery
- description
- Patient is scanned with whole body Fdg PET/CT and contrast-enhanced CT in a row within 3 weeks preoperatively. Findings are compared with intraoperative surgical status evaluated by operator and confirmed with biopsies.
Secondary outcomes (4)
- measure
- Neoadjuvant chemotherapy (NACT) response evaluation with PET/CT compared with contrast-enhanced CT after 3 cycles of chemotherapy
- timeFrame
- Outcome measure: after interval debulking surgery, about 4 months
- description
- Fdg PET/CT and a contrast-enhanced CT are performed in a row at the time of diagnosis and repeated after 3 cycles of chemotherapy. Finding are compared with disease status in the interval debulking surgery evaluated by operator and histological specimen.
