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.

Abstract

purposeHistone deacetylase inhibitors (HDACis) have been shown to overcome resistance to epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) linked to epigenetic changes and epithelial-mesenchymal transition (EMT) state. This randomized phase II study evaluated the outcome of erlotinib with and without the isoform selective HDACi, entinostat. PATIENTS AND

methodsPreviously treated patients with stage IIIB/IV non-small-cell lung cancer, no prior EGFR-TKIs, and performance status ≤ 2 were randomly administered erlotinib 150 mg on days 1 through 28 plus entinostat 10 mg orally on days 1 and 15 every 28 days (EE) or erlotinib plus placebo (EP). The primary end point was 4-month progression-free survival (PFS) rate with additional end points including 6-month PFS rate, PFS, and overall survival (OS). Exploratory analyses included EMT- and EGFR-related biomarker analysis on archival tissue.

resultsOne hundred thirty-two patients were enrolled (EE, 67; EP, 65). The 4-month PFS rate was comparable for both groups (EE, 18% v EP, 20%; P = .7). In the subset of patients with high E-cadherin levels, OS was longer in the EE group compared with the EP group (9.4 v 5.4 months; hazard ratio, 0.35; 95% CI, 0.13 to 0.92; P = .03) with a corresponding trend toward increased PFS. The adverse event (AE) profile was acceptable, with rash, fatigue, diarrhea, and nausea the most common AEs in both groups.

conclusionErlotinib combined with entinostat did not improve the outcomes of patients in the overall study population when compared with erlotinib monotherapy. High E-cadherin expression levels at time of diagnosis indicate an increased sensitivity to HDACi/EGFR-TKI inhibition providing the basis for a biomarker-driven validation study.
