Study acronymCHORUS
Study objectivesThe aim of this trial is to assess the acceptability of this randomised trial to clinicians and patients. It is intended that between 100 and 150 patients be randomised over a period of 18 months. If this is achieved, a large phase III trial is planned to follow on from this feasibility trial. The aim of the phase III trial is to determine the impact of the timing of surgery and chemotherapy in patients with advanced epithelial ovarian, primary peritoneal, or fallopian tube cancer, in terms of survival, progression-free survival, and quality of life.

Health condition(s) or problem(s) studiedAdvanced epithelial ovarian, primary peritoneal or fallopian tube carcinoma
InterventionPrimary surgery arm (control):
This comprises radical surgery followed by 6 cycles of carboplatin-based chemotherapy at 3-weekly intervals. The interval between randomisation and the initiation of surgery should be a maximum of 4 weeks. Chemotherapy should commence within 6 weeks of primary surgery. Interval debulking surgery may be carried out at the discretion of the clinician if appropriate and if stated as the intention prior to randomisation; this should be carried out as close as possible to 3 weeks after the 3rd cycle of chemotherapy. Chemotherapy should be resumed within 6 weeks of interval debulking surgery.

Neoadjuvant chemotherapy arm:
This comprises histological or cytological confirmation of disease followed by 3 cycles of carboplatin-based chemotherapy at 3-weekly intervals. Neoadjuvant chemotherapy should be carried out within 4 weeks of randomisation. Surgery following neoadjuvant chemotherapy to be performed as close as possible to 3 weeks after the 3rd cycle of chemotherapy. A further 3 cycles of carboplatin-based chemotherapy should be given within 6 weeks of surgery.

Doses of chemotherapy regimens:
Paclitaxel and carboplatin combination:
Paclitaxel 175 mg/m2, Carboplatin 5 x (51Cr-EDTA or measured clearance + 25) mg or 6 x (calculated clearance + 25) mg repeated every 3 weeks for 6 cycles
Carboplatin as a single agent:
Carboplatin 6 x (51Cr-EDTA or measured clearance + 25) mg or 7 x (calculated clearance + 25) mg
The chemotherapy regimens chosen were based on results from the ICON3 trial.
