Strategy for PSA progression in patients undergoing salvage radiation for biochemical recurrence after radical prostatectomy.
Article in International journal of clinical oncology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundThe treatment strategy for prostate-specific antigen (PSA) progression in patients who receive salvage radiation therapy (RT) for biochemical recurrence (BCR) after radical prostatectomy (RP) is salvage androgen deprivation therapy (ADT). However, its optimal timing is highly controversial.
methodsThe study sample consisted of 77 men who underwent RP, received salvage RT against BCR, and underwent salvage ADT for PSA progression. The endpoint of this study was development to castration-resistant prostate cancer (CRPC), from the start of salvage RT.
resultsThe median follow-up time was 9.5 years, and 20 patients experienced CRPC. The multivariable analysis identified PSA-doubling time (PSA-DT) ≤ 12 months (hazard ratio, 3.5) and seminal vesicle invasion (SVI) (hazard ratio, 4.4) as independent risk factors. We defined the high-risk and low-risk groups as those with one or two risk factors and no risk factors, respectively. In the high-risk group, a significant difference in time to CRPC was observed between patients who received salvage ADT at PSA ≤ 1.0 ng/mL (n = 8) and at > 1.0 ng/mL (n = 27) (10-year non-CRPC rate: 100.0% vs. 46.3%, respectively). In contrast, in the low-risk group, no significant difference in CRPC-free survival was observed between patients who received salvage ADT at PSA ≤ 1.0 ng/mL (n = 14) and at > 1.0 ng/mL (n = 28) (10-year non-CRPC rate: 86.4% vs. 80.8%, respectively).
conclusionIn high-risk patients (PSA-DT ≤ 12 months and/or SVI), salvage ADT for PSA progression after salvage RT should be started before the PSA levels exceed 1.0 ng/mL.
