Treatment outcomes and comparative survival analysis of intraductal carcinoma of the prostate.
Article in International urology and nephrology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Not yet cited in PubMed.
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
purposeIntraductal carcinoma of the prostate is a rare subset of prostate cancer, for which no consensus treatment guidelines exist. We seek to investigate treatment and survival outcomes for IDC-P in the context of current NCCN guidelines.
methodsThe Surveillance, Epidemiology, and End Results (SEER) database was queried to identify patients with intraductal carcinoma of the prostate diagnosed between 2000 and 2020. Cox regression analysis and log-rank comparisons of both overall and cause-specific survival over 5- and 10-year timeframes were conducted.
results945 patients were identified. Cox regression analysis demonstrated treatment with unimodal surgery (hazard ratio (HR) = 3.70, p = 0.005) was associated with decreased 10-year cause-specific survival, while unimodal treatment with radiotherapy was associated with decreased 5- and 10-year overall survival (HR = 2.14, p = 0.025; HR = 2.16, p = 0.005, respectively). Univariate survival subanalysis of treatment regimens demonstrated decreased 5-year cause-specific (p = 0.004) and overall (p = 0.019) survival among patients that received only radiotherapy as treatment. Radical prostatectomy alone was non-inferior to radical prostatectomy with adjuvant radiotherapy in the context of 10-year overall survival (90% vs 80%; p = 0.58).
conclusionDifferences in both 5- and 10-year overall survival and cause-specific survival were present among patients diagnosed with IDC-P. Treatment with unimodal radiotherapy among patients with IDC-P was associated with decreased survival compared to treatment with radical prostatectomy ± adjuvant radiotherapy, while radical prostatectomy alone was non-inferior to radical prostatectomy with adjuvant radiotherapy. Further research into the risk stratification and optimal treatment of these patients is warranted.
