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

DNA mismatch repair (MMR) is one of many evolutionarily conserved processes that act as guardians of genomic integrity. MMR proteins recognize errors that occur during DNA replication and initiate countermeasures to rectify those mistakes. MMR deficiency (MMRd) therefore leads to a dramatic accumulation of mutations. The MMRd genomic signature is characterized by a high frequency of single-base substitutions as well as insertions and/or deletions that preferentially occur in short nucleotide repeat sequences known as microsatellites. This accumulation leads to a phenomenon termed microsatellite instability, which accordingly serves as a marker of underlying MMRd. MMRd is associated with hereditary cancer syndromes such as Lynch syndrome and constitutional MMRd as well as with sporadic tumour development across a variety of tissues. High baseline immune cell infiltration is a characteristic feature of MMRd/microsatellite instability-high tumours, as is the upregulation of immune checkpoints. Importantly, the molecular profile of MMRd tumours confers remarkable sensitivity to immune-checkpoint inhibitors (ICIs). Many patients with MMRd disease derive durable clinical benefit when treated with these agents regardless of the primary tumour site. Nevertheless, a substantial subset of these patients will fail to respond to ICI, and increasing research is focused on identifying the factors that confer resistance. In this Review, we begin by discussing the biological function of the MMR machinery as well as the genomic sequelae of MMRd before then examining the clinical implications of MMRd with a specific focus on cancer predisposition, diagnostic approaches, therapeutic strategies and potential mechanisms of resistance to ICIs.
