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

purposeNumerous treatment breakthroughs for patients with metastatic castration-resistant prostate cancer (mCRPC) have been demonstrated in clinical trials in the past 15 years. However, real-world evidence on the changing epidemiology and longevity of this population has not been demonstrated. This study assessed prevalence trends for mCRPC over eight years in a large managed care population.

methodsIn a claims database, adult male patients were included with ≥ 1 claim for prostate cancer, pharmacologic/surgical castration, and metastatic disease during the identification period. The index mCRPC date was the first metastatic claim; six months of continuous enrollment before and after was required. Patients with metastatic disease at baseline were excluded. Patients were followed until death, end of study, or disenrollment, whichever was earliest. Total, mCRPC per-prostate cancer, and age-specific prevalence rates were calculated cross-sectionally for each year under study (2010-2017).

resultsOf 343,089 patients identified with a claim for prostate cancer, 3690 mCRPC cases (1.1%) were identified. Incidence (new cases per year) remained relatively constant over the study period while prevalence of mCRPC (total cases per year) increased. mCRPC prevalence increased with increasing age. Total and mCRPC per-prostate cancer prevalence rates increased in monotonic, year-over-year trends from 2010 to 2017, while incidence (new cases per year) of mCRPC remained relatively stable.

conclusionThis study found increasing prevalence of mCRPC in an insured patient population during the 8-year period, coupled with stable incidence, validating that patients with the disease are living longer. With the addition of androgen receptor-directed therapies and poly(ADP-ribose) polymerase inhibitors in recent years, this trend will likely continue.
