A Phase 3 interventional study of Maximal cytoreductive surgery and HIPEC in Ovarian Epithelial Cancer Recurrent, sponsored by UNICANCER. Active, not recruiting at 33 sites in 3 countries. Open to female participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-05-20.

CHIPOR hypothesis is that the adjunction of platinum HIPEC in first relapsed epithelial ovarian cancer is able to improve the median Overall Survival (OS) by 12 months. In that hypothesis, with alpha risk of 5%, a power beta of 80%, during a 3 years period of inclusion and a 3 years follow-up, the number of patients to include is 404. Taking into account a 10% failure, an overall number of 444 patients is required.
The patient received before the surgery a second line chemotherapy, platinum-based regimen with either carboplatine-paclitaxel, or carboplatine-caelyx. At the end of the six courses IV chemotherapy, if the disease is still responding and if a complete cytoreductive surgery seems possible, the patient is included after signed informed consent and will be operated 5 to 8 weeks after the last second-line chemotherapy cycle.
So, during the surgery the patient will be randomized if the complete cytoreductive surgery is really done and will then receive:
The HIPEC will be done at the end of the surgery. At the end of cytoreductive surgery, tumor residual disease must be null or very limited (Sugarbaker completeness cytoreduction: CC0 (no residual)-CC1 (residual \< 0.25cm).
Two methods will be used for the HIPEC: Open or closed abdomen, depends on the site practice. Each site will use the same method during the study for all included patients.
UNICANCER is the lead sponsor of 215 studies on the registry; 52 are open to participants now.
Counted across the registry records on this site, refreshed daily.
