Eldest gastric cancer patient with high microsatellite instability responding to pembrolizumab.
Article in International cancer conference journal, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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.
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
Pembrolizumab has been associated with a high tumor response rate among high microsatellite instability (MSI-H) cancer patients. The efficacy and safety of pembrolizumab in the treatment of MSI-H gastric cancer (GC) patients aged ≥ 85 years have not been reported. This study reports the case of an 89-year-old woman diagnosed with stage IIA MSI-H GC based on her chief complaint of abdominal pain. We considered surgery, but it was contraindicated due to the patient's age and cardiovascular comorbidity. Therefore, we administered pembrolizumab after receiving approval from the ethics committee, and no significant adverse events were noted. The tumor was markedly responsive to pembrolizumab, and the computed tomography and endoscopic findings revealed a complete response. This is the first report on the efficacy and safety of pembrolizumab in the treatment of GC in an "oldest old" patient with MSI-H.
