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

Resistance to chemotherapy provides a major challenge in treatment of metastatic cancer. Prolonged exposure to almost any drug regimen leads to the formation of resistant subclones in almost all advanced solid tumors. Tumor heterogeneity because of intrinsic genetic instability is seen as one of the major contributing factors. In this work, we present evidence that genetic instability measured by mutation frequency is induced by treatment with the EGFR inhibitor afatinib or cisplatin in head and neck squamous cancer cells. We find that APOBEC3B and polymerase iota are upregulated, and inhibition of MEK1/2 by U0126 leads to downregulation on the protein level. Costimulation of afatnib and cisplatin with U0126 leads to a significantly lower mutation frequency. These findings may represent a molecular mechanism for dynamically controlling genetic instability during chemotherapy in head and neck squamous cell carcinoma (HNSCC) cancer cells.
