1 · What the graph read from it

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.

2 · The registry

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

purpose of reviewPARP inhibitors (PARPi) have rapidly reshaped the treatment landscape for metastatic prostate cancer, moving from biomarker-selected monotherapy in metastatic castration-resistant prostate cancer (mCRPC) to first-line combination strategies with androgen receptor pathway inhibitors (ARPIs) and more recently, into metastatic hormone-sensitive disease (mHSPC). This review summarizes the evidence-based use of PARPi in metastatic prostate cancer, integrating the mechanistic rationale and guideline perspectives. We also highlight the resistance mechanisms that inform patient selection and underpin emerging strategies. RECENT

findingsThe most consistent and clinically meaningful benefit from PARPi is observed among patients with deleterious BRCA1/2 alterations, whereas outcomes among patients with non- BRCA defective homologous recombination repair (HRR) gene subsets are heterogeneous and often modest. Pairing PARPi with ARPI in mCRPC patients bearing HRR mutations, especially BRCA1/2 mutations, not only improves clinical outcomes but also increases toxicity. Furthermore, uncertainty remains regarding the overall impact of the incremental benefit of PARPi/ARPI combinations over sequential therapy. Expansion into mHSPC further underscores the field's shift toward earlier, genomically guided treatment intensification strategies. SUMMARY: Clinical practice is converging on early comprehensive genomic testing and prioritization of PARPi-based therapy for HRR-altered, especially BRCA1/2 -mutated, prostate cancer. Key research priorities include functional biomarkers beyond gene panels, rational combinations to prevent/overcome resistance, and optimized sequencing across disease states.
