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

Primary vaginal cancer is a rare malignancy with a lack of international guidelines and supporting clinical trial evidence to guide decision making. Historical results have shown poor outcomes with chemotherapy for stage IVB vaginal squamous cell carcinoma (SCC). The evolving role of checkpoint inhibitors in rare gynaecological cancers prompted us to investigate the role of pembrolizumab in this setting. The efficacy of pembrolizumab in vaginal SCC has never been investigated in any clinical trial. There is established data to support the use of concurrent chemoradiotherapy in gynaecological cancers, however, the data for concurrent use of immunotherapy and radiotherapy is still lacking but is the subject of several clinical trials. We herein present the first reported case of chemotherapy refractory vaginal SCC with complete response to pembrolizumab and concurrent pelvic radiotherapy. We also present wall-eyed bilateral internuclear ophthalmoplegia (WEBINO) as a rare but new immune related adverse event.
