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

Invasive malignant melanoma (MM) is an aggressive tumor with no curative therapy in advanced stages. Chemotherapy has not demonstrated its efficacy in MM and current treatment for tumors carrying the most frequent BRAFV600E mutation consists of BRAF inhibitors alone or in combination with MAPK pathway inhibitors. We previously found that BRAF inhibition prevents activation of the DNA-damage repair (DDR) pathway in colorectal cancer thus potentiating the effect of chemotherapy. We now show that different chemotherapy agents inflict DNA damage in MM cells, which is efficiently repaired, associated with activation of the ATM-dependent DDR machinery. Pharmacologic inhibition of BRAF impairs ATM and DDR activation in these cells, leading to sustained DNA damage. Combination treatments involving DNA-damaging agents and BRAF inhibitors increase tumor cell death in vitro and in vivo, and impede MM regrowth after treatment cessation. We propose to reconsider the use of chemotherapy in combination with BRAF inhibitors for MM treatment.
