Introduction/Background*In advanced ovarian cancer surgery, there is rather limited published evidence, drawn from a small sample, providing information about risk factors for anastomotic leak.

Methodology In our previous work, Twelve pre-/intraoperative variables were analysed as potential independent risk factors for anastomotic leak. A predictive model was created to stablish the risk of anastomotic leak for a given patient.

Result(s)*The validation of our proposed predictive model will emerge from the collaborative research performed by 12 centers: 6 from Spain, 2 from United Kingdom, 1 from Italy, 1 from France and 2 from Germany.

Conclusion*Due to the low incidence of AL in ovarian cancer patients, a restrictive stoma policy based on the presence of risk factors should be the actual recommendation. The AL risk for each patient can be predicted by our multivariate model.
