High 11-Ketotestosterone Linked to Shorter Time to Castration Resistance in Recurrent Nonmetastatic Prostate Cancer.

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
purposeThe contribution of 11-oxygenated androgens to the progression of lethal prostate cancer (PCa) remains unresolved. We hypothesized that evaluating circulating levels of 11-oxygenated androgens, such as the androgen receptor agonist 11-ketotestosterone (11KT), could serve as a potential predictor of the onset of castration-resistant PCa (CRPC). MATERIALS AND
methodsWe used mass spectrometry to quantify 11-oxygenated androgens in postoperative plasma samples acquired from 145 patients who subsequently received androgen deprivation therapy for biochemical recurrence and achieved castrated testosterone levels. Kaplan-Meier survival analyses and multivariable Cox models were used to investigate relationships between steroids and CRPC.
resultsOf 145 patients, 31 developed CRPC with a median time to CRPC of 57 months. 11-Oxygenated androgen levels were unaffected by androgen deprivation therapy, which stands in contrast to the observed changes in testosterone and other steroids. 11KT was the most abundant androgen but was not linked to clinical features. Kaplan-Meier analysis revealed that 11KT levels above the median of 273 pg/mL were associated with a shorter time to CRPC (
conclusions11KT is a key component of the hormonal profile predictive of earlier onset of CRPC. Enhancing our understanding of the specific role of 11KT in the progression to CRPC could help optimize hormonal therapy for castration-sensitive patients with PCa and CRPC.
