The Omission of Upfront Treatment Intensification Does Not Adversely Affect Oncological Outcomes in a Subset of Castration-Highly Sensitive Metastatic 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
BACKGROUND/
aimIn patients with metastatic castration-sensitive prostate cancer (mCSPC), upfront treatment intensification with the addition of new hormonal agents and/or docetaxel to androgen deprivation therapy (ADT) is recommended. However, this modality is potentially excessive in a subset of these patients. This study aimed to identify patients who may be eligible to omit upfront treatment intensification. PATIENTS AND
methodsPatients with mCSPC who underwent ADT were enrolled. The association between undetectable prostate-specific antigen (PSA) (<0.2 ng/ml) after ADT initiation and overall or castration-resistance-free survival was evaluated.
resultsNinety-seven out of the 242 enrolled patients had low-risk and/or low-volume cancer and were further analyzed. Of these, 45 (46.4%) patients achieved undetectable PSA. The median follow-up period after ADT initiation was 70 months. The median overall survival among patients with undetectable PSA was quite long, reaching 226 months and significantly longer than that among patients with detectable PSA [71 months, hazard ratio (HR)=0.27, 95% confidence interval (CI)=0.15-0.49, p<0.001]. Time to development of castration-resistance was also long and significantly longer in the undetectable PSA group than that in the detectable PSA group (median: 124 vs. 17 months, HR=0.20, 95% CI=0.12-0.34, p<0.001).
conclusionPatients with low-risk and/or low-volume mCSPC showed long-term survival when undetectable PSA was achieved during conventional ADT. In these patients, skipping upfront treatment intensification does not seem to negatively impact survival.
