Circulating tumor DNA-guided treatment decision in metastatic castration-resistant prostate cancer patients: a cost-effectiveness analysis.
Article in Therapeutic advances in medical oncology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled 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.
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: The androgen receptor pathway inhibitors (ARPI), abiraterone acetate and enzalutamide, are commonly used in first-line treatment of patients with metastatic castration-resistant prostate cancer (mCRPC). However, early resistance to ARPI treatment occurs frequently. Traditionally, the response is evaluated 3-6 months after the start of treatment. However, recent findings indicate that by detecting circulating tumor DNA (ctDNA) at baseline and 4 weeks after ARPI treatment initiation, patients with a nondurable response can be identified after 4 weeks of treatment, enabling an early switch to alternative treatments. Objective: This study aims to evaluate the cost-effectiveness of ctDNA-guided treatment switch after 4 weeks of ARPI therapy in mCRPC patients compared to standard of care. Design: A cost-effectiveness analysis. Methods: A cost-effectiveness analysis was conducted by creating a Markov state transition model to simulate progression, mortality, and treatment costs over a 5-year time horizon comparing ctDNA-guided care versus standard of care. The outcomes measured were incremental treatment costs per life-years and quality-adjusted life-years (QALYs) gained. Results: The analysis showed an incremental cost-effectiveness ratio of €65,400.86 per QALY gained and an incremental net monetary benefit of €2716.62. Thereby, the use of ctDNA-guided treatment was cost-effective in comparison to standard care in 74% of the simulations using a willingness-to-pay threshold of €80,000 per QALY gained. Conclusion: Our study demonstrated the cost-effectiveness of using a ctDNA-guided early therapy switch in non-responders after only 4 weeks of first-line ARPI therapy in mCRPC patients. This paves the way for implementing ctDNA-guided treatment decisions in clinical practice.
