1 · What the graph read from it

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.

2 · The registry

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

introductionFocal therapy (FT) ablates areas of prostate cancer rather than treating the whole gland. We compared oncological outcomes of FT to radical prostatectomy (RP).

methodsUsing prospective multicentre databases of 761 FT and 572 RP cases (November/2005-September/2018), patients with PSA < 20 ng/ml, Gleason </= 4 + 3 and stage </= T2c were 1-1 propensity score-matched for treatment year, age, PSA, Gleason, T-stage, cancer core length and use of neoadjuvant hormones. FT included 1-2 sessions. Primary outcome was failure-free survival (FFS) defined by need for salvage local or systemic therapy or metastases. Differences in FFS were determined using Kaplan-Meier analysis with log-rank test.

results335 radical prostatectomy and 501 focal therapy patients were eligible for matching. For focal therapy, 420 had HIFU and 81 cryotherapy. Cryotherapy was used predominantly for anterior cancer. After matching, 246 RP and 246 FT cases were identified. For radical prostatectomy, mean (SD) age was 63.4 (5.6) years, median (IQR) PSA 7.9 g/ml (6-10) and median (IQR) follow-up 64 (30-89) months. For focal therapy, these were 63.3 (6.9) years, 7.9 ng/ml (5.5-10.6) and 49 [34-67] months, respectively. At 3, 5 and 8 years, FFS (95%CI) was 86% (81-91%), 82% (77-88%) and 79% (73-86%) for radical prostatectomy compared to 91% (87-95%), 86% (81-92%) and 83% (76-90%) following focal therapy (p = 0.12).

conclusionsIn patients with non-metastatic low- intermediate prostate cancer, oncological outcomes over 8 years were similar between focal therapy and radical prostatectomy.
