Prevention and management of PARP inhibitor-related haematological toxicities in prostate cancer: French expert opinion using the Delphi method.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Haematological toxicities (anaemia, neutropenia and thrombocytopenia), a known class effect of poly-ADP ribose polymerase inhibitors (PARPi) may limit exposure to PARPi and therefore impact efficacy. Objective: This study aimed to provide practical and detailed recommendations for the prevention and management of these toxicities in metastatic prostate cancer in the real world. Design: A national consensus study was performed using a modified Delphi methodology. Methods: A multidisciplinary steering committee of 9 French experts formulated and submitted 38 statements to the vote of 33 French healthcare professionals experienced in oncology and PARPi in prostate and/or breast/ovarian cancers. Results: All recommendations achieved a consensus. Before initiating PARPi, haematological disorders should be investigated and appropriate corrective measures implemented. The haemoglobin level should ideally be ⩾10 g/dl and a minimum delay of 4 weeks should be respected after chemotherapy. Monitoring should be frequent for the first 3 months of treatment, at least every 15 days, and even more frequent in patients at high-risk of toxicity. In the event of symptomatic grade 2 or 3 anaemia, grade 2 or 3 thrombocytopenia and grade 3 neutropenia, PARPi treatment should be discontinued until return to grade 1. Transfusion may be considered in symptomatic grade 2 or 3 anaemia. Myelodysplastic syndrome/acute myeloid leukaemia should be suspected in cases of cytopenia persisting beyond 4 weeks or changes in the blood count after maintenance of an optimal therapeutic dose over the long term. Conclusion: These proposals complement existing recommendations to guide healthcare professionals in real-world practice, and so optimise metastatic prostate cancer patient's ability to maximally benefit from PARPi.
