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

Colon adenocarcinoma is a well-studied surgical pathology with a streamlined treatment regimen. The typical areas of disease metastasis include liver and lungs, however, there have been reports of unusual locations of disease spread. This includes metastases to the breast, thyroid and testes, which often lead to deferral from conventional treatments. An 83-year-old female presented to her general practitioner with dizziness, fatigue, and altered bowel motions. Subsequently, a surgeon is confronted with this case of mucinous adenocarcinoma with axillary metastasis, diagnosed by FluoroDeoxyGlucose (FDG) Positron Emission Tomography (PET) with Computed Tomography (CT) and confirmed with biopsy. Her tumour was found to be both microsatellite instability/mismatch repair (MSI/MMR) deficient and KRAS A146V positive. How should this influence treatment? We discuss this pathology, its treatment implications, as well as a brief literature review. This is the first case of metastatic colorectal cancer to the axilla in Australia and the only reported of such cases in literature with both MSI/MMR deficiency and KRAS146V mutation.
