Salvage prostate bed plus elective pelvic node radiation without androgen deprivation therapy.
Article in Journal of cancer research and clinical oncology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. 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
background and purposeIn men with biochemical recurrence (BCR) of prostate cancer (PCA) after radical prostatectomy (RP), there is limited data on the effectiveness of adding elective pelvic nodal radiation (EPNI) to salvage prostate bed radiation (PBRT) without androgen deprivation therapy (ADT) to prevent progression. MATERIALS AND
methodsRetrospective chart review of 326 patients treated for BCR of PCA from a single institution was performed to capture baseline pre-operative PSA, pathologic details, post-operative PSA, treatment details (radiation and ADT), subsequent failure (rising PSA), response to radiation, and subsequent outcomes after radiation.
resultsBetween 2004 through 2017, 326 patients received PBRT. Majority (n = 253; 78%) did not receive ADT. Majority received EPNI (n = 227; 90%) with salvage PBRT (n = 213; 94%). The median pre-PBRT PSA was 0.50 ng/ml (0.10-75.60 ng/ml). Of the patients that did not receive ADT, 83% (210/253) achieved an undetectable (< 0.2 ng/ml) PSA after salvage PBRT. After a median follow-up of 87 months, 172 (53%) patients were without a rising PSA and 50 (15%) developed metastatic disease.
conclusionOutcomes with salvage PBRT plus EPNI without ADT appear comparable to salvage PBRT plus EPNI plus ADT. These results need confirmation in a randomized setting.
