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

Men with metastatic castration-resistant prostate cancer (mCRPC) frequently have circulating tumor cells (CTCs) that are detectable in their peripheral blood. The CellSearch® method of enumerating CTCs is presently the only FDA-cleared CTC test available clinically for men with mCRPC and has been shown to have prognostic significance in this setting, both before and during systemic therapy. Clinical utility, reflecting the ability of this test to favorably change outcomes, is a more controversial and higher bar. The CellSearch® CTC assay can provide updated prognostic and potentially surrogate information in specific clinical scenarios and in clinical trials, but formal randomized trials of clinical utility remain an unmet clinical need. Recent data suggest that CTCs may harbor genetic information (such as the androgen receptor splice variant 7, AR-V7) relevant to changing clinical management and predicting treatment sensitivity or resistance to cancer therapies such as enzalutamide, abiraterone, and taxane chemotherapies. Further molecular characterization of CTCs, cell-free DNA, or RNA can also provide additional information that may have clinical utility. Thus, CTC research is moving toward predictive medicine, based on the biologic characterization and improvements in clinical outcomes associated with heterogeneous cell types both within and between patients.
