Controversies in the treatment of advanced ovarian cancer in the PARP inhibitors era: a Delphi consensus

Objective: Our aim was to reach a consensus on the management of the most controversial issues of advanced ovarian cancer.Methods: Nominal group and Delphi techniques were used. A steering committee of 5 experts analyzed current management of advanced ovarian cancer, identified controversies, critically analyzed the evidence, and formulated guiding statements for clinicians. Subsequently, a panel of 15 experts was selected to test agreement with the statements through two Delphi rounds. Items were scored on a 4-point Likert scale from 1 (totally disagree) to 4 (totally agree). In the first and second rounds, consensus was considered if & GE;70% of answers pertained to category 1 or category 4.Results: Overall, 112 statements were incorporated in the following areas: 1) biomarkers and hereditary ovarian cancer; 2) first-line treatment; 3) recurrent disease when platinum might be the best option; and 4) post-poly(adenosine diphosphate-ribose) polymerase (PARP) inhibitors setting. In the first Delphi round, 37 statements reached consensus and did thus not pass to the second round. After the second round, another 18 statements reached consensus. Forty-six of the consensus were with the agreement and 9 with the disagreement.Conclusion: Through the methodology used, a consensus was reached in approximately half of the statements. The results of this work may be useful in addressing the most controversial issues on the management of advanced ovarian cancer.
