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

Approximately 30% of human cancers harbor a gain-in-function mutation in the RAS gene, resulting in constitutive activation of the RAS protein to stimulate downstream signaling, including the RAS-mitogen activated protein kinase pathway that drives cancer cells to proliferate and metastasize. RAS-driven oncogenesis also promotes immune evasion by increasing the expression of programmed cell death ligand-1, reducing the expression of major histocompatibility complex molecules that present antigens to T-lymphocytes and altering the expression of cytokines that promote the differentiation and accumulation of immune suppressive cell types such as myeloid-derived suppressor cells, regulatory T-cells, and cancer-associated fibroblasts. Together, these changes lead to an immune suppressive tumor microenvironment that impedes T-cell activation and infiltration and promotes the outgrowth and metastasis of tumor cells. As a result, despite the growing success of checkpoint immunotherapy, many patients with RAS-driven tumors experience resistance to therapy and poor clinical outcomes. Therefore, RAS inhibitors in development have the potential to weaken cancer cell immune evasion and enhance the antitumor immune response to improve survival of patients with RAS-driven cancers. This review highlights the potential of RAS inhibitors to enhance or broaden the anti-cancer activity of currently available checkpoint immunotherapy.
