Values of alkaline phosphatase at the diagnosis of castration resistance and response to primary androgen deprivation therapy as predictors of subsequent metastasis in non-metastatic castration-resistant 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
purposeAmong various therapeutic options available for metastatic castration-resistant prostate cancer (mCRPC), only apalutamide and enzalutamide have shown evidences of improved metastasis-free survival (MFS) for non-metastatic castration-resistant prostate cancer (nmCRPC). However, there is a paucity of evidence to indicate who may be targeted for aggressive therapy among patients with nmCRPC. The objectives of this retrospective study were to explore predictors of metastasis in patients with nmCRPC and to identify a subpopulation of patients with nmCRPC who may benefit from aggressive therapy.
methodsA total of 115 patients with CRPC who had no metastasis detected at the time of diagnosis of CRPC were included in this retrospective study. All patients were treated at Jikei University and its affiliated hospitals. The primary outcome measure was MFS from the time of diagnosis of CRPC. Predictors of MFS were also explored with a multivariate Cox hazard model.
resultsThe median observation period after diagnosis of CRPC was 30 months (range 2-143 months). Kaplan-Meier analysis revealed a median MFS of 76. Multivariate analysis demonstrated that low alkaline phosphatase (ALP) values at diagnosis of CRPC and favorable response to primary androgen deprivation therapy (ADT) were significant predictors of longer MFS (P = 0.011, and 0.031, respectively).
conclusionsResults of this study suggest that high ALP values at diagnosis of CRPC and poor response to primary ADT may predict the propensity of metastasis in patients with nmCRPC. Further prospective studies will be required enrolling more patients to confirm our findings.
