Objective: There are no data, and thus no consensus, on the optimal duration of poly(ADP-ribose) polymerase (PARP) inhibitor maintenance therapy for exceptional responders (here defined as progression-free for 5 years or longer) with platinum sensitive recurrent ovarian cancer. The current licence is to continue PARP inhibitors until progression or toxicity; however, international practice varies considerably. The risks of late progression and late-onset myeloid malignancies, defined as occurring beyond 5 years of PARP inhibition, are unknown. This study aims to examine the practice patterns and opinions regarding the management and surveillance protocols of exceptional responders with platinum sensitive recurrent ovarian cancer.
Methods: An online international survey of experts from June 2023 to June 2024 was carried out, disseminated at Gynaecologic Cancer Intergroup meetings and by Chairs of Cooperative Groups.
Results: 210 responses were received from 26 countries including Australia (27 respondents), Germany (24), the UK (21), the Netherlands (16), France (13), Spain (12), Canada (12), Italy (11), Japan (11), and other countries (63). Most respondents did not have institutional or trials group guidelines regarding duration of PARP inhibitors (154, 73.3%). For the minority with guidelines, recommendations varied: 1 year (2), 2 years (13), 3 years (4), and indefinite treatment (22). Individual practice varied considerably for those without guidelines: most (116, 76.3%) recommended ≥5 years of PARP inhibition, of which 73 (48.0%) recommended indefinite PARP inhibition. Sixty-six respondents (31.4%) reported having patients with late progression and 46 (22.0%) had cases with late-onset myeloid malignancies. Surveillance practices varied widely across all respondents.
Conclusions: This international survey highlights the diverse practice variations and disparate views on the optimal duration of maintenance therapy with PARP inhibitors in platinum sensitive recurrent ovarian cancer. The responses suggest a notable risk of late progression and myelodysplastic syndrome/acute myeloid leukemia among exceptional responders which needs confirmation. Detailed individual patient data is required to draw more reliable conclusions; another study is underway addressing this.
