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

backgroundTo explore whether metastatic castration-resistant prostate cancer (mCRPC) patients with distinct intraductal carcinoma of the prostate (IDC-P) subtypes respond differently to abiraterone and docetaxel treatment.

methodsWe retrospectively analyzed data of 170 mCRPC patients receiving abiraterone or docetaxel as first-line therapy. PSA response, PSA progression-free survival (PSA-PFS), radiographic progression-free survival (rPFS), and overall survival (OS) were analyzed based on the presence of IDC-P and its subpatterns.

resultsIDC-P was confirmed in 91/170 (53.5%) patients. Among them 36/91 (39.6%) and 55/91 (60.4%) harbored IDC-P patterns 1 and 2, respectively. Patients with IDC-P pattern 1 shared similar clinical outcomes to those without IDC-P in both abiraterone and docetaxel treatment. However, against cases without IDC-P or with IDC-P pattern 1, patients with IDC-P pattern 2 had markedly poorer prognosis in either abiraterone (mPSA-PFS: 11.9 vs. 11.1 vs. 6.1 months, p < 0.001; mrPFS: 18.9 vs. 19.4 vs. 9.6 months, p < 0.001) or docetaxel (mPSA-PFS: 6.2 vs. 6.6 vs. 3.0 months, p < 0.001; mrPFS: 15.1 vs. 12.6 vs. 5.5 months, p < 0.001) treatment. For patients without IDC-P, docetaxel had comparable therapeutic efficacy with abiraterone. However, the efficacy of docetaxel was significantly inferior to abiraterone in patients with either IDC-P pattern 1 (mPSA-PFS: 6.6 vs. 11.1 months, p = 0.021; mrPFS: 12.6 vs. 19.4 months, p = 0.027) or pattern 2 (mPSA-PFS: 3.0 vs. 6.1 months, p = 0.003; mrPFS: 5.5 vs. 9.6 months, p = 0.007).

conclusionCompared to docetaxel, abiraterone exhibited better efficacy in patients with IDC-P of either pattern. However, IDC-P pattern 2 responded unsatisfactorily to either abiraterone or docetaxel therapy. Novel therapeutic strategies for IDC-P pattern 2 need further investigations.
