Squamous Cell Carcinoma of Duodenum Secondary to Metastasis From Recurrent Head and Neck Cancer: A Case Report and Literature Review.
Article in Cureus, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
This report describes a case involving the diagnosis and treatment of squamous cell carcinoma (SCC) of the duodenum, which was found to be a metastatic lesion originating from recurrent head and neck cancer (HNC) in a 74-year-old female patient. The patient had a past medical history of gastroesophageal reflux disease (GERD), tonsillar SCC, and recurrent HNC. She presented with symptoms of burning, tingling, and numbness of the throat and left side of the tongue. Upon examination with an esophagogastroduodenoscopy, an ulcerated hard area mass was detected in the third portion of the duodenum. Biopsy results confirmed the mass to be a metastatic poorly differentiated SCC. The incidence of head and neck squamous cell carcinoma (HNSCC) metastasis to the duodenum is rare, likely due to the unique anatomic location and the lack of lymphatic drainage in the area. The patient was treated with a combination of paclitaxel, carboplatin, and pembrolizumab. This case underscores the significance of considering unusual sites of metastasis in HNSCC patients and utilizing advanced imaging modalities and immunotherapy to detect and treat these locations effectively.
