Finger gangrene as initial manifestation of esophageal squamous cell carcinoma: a case report.
Article in Frontiers in oncology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Esophageal cancer exhibits a high incidence in the Chaoshan region of south China, an area characterized by distinctive dietary habits prominently featuring the consumption of preserved pickles and hot tea. Common metastatic sites of esophageal cancer include the lungs, liver, brains, and bones, while occurrence in the distal ends of the limbs is exceptionally rare. Here we present a case of a 62-year-old man from China's Chaoshan region presented with progressive right ring finger pain, swelling, and gangrene. After the amputation of digit, histopathology unexpectedly identified well-differentiated esophageal squamous cell carcinoma (ESCC) with positive margins. A comprehensive retrospective evaluation of medical history identified previously undocumented intermittent dysphagia and mild thoracodorsal pain, postdating the initial presentation of digital symptom by one months. The Esophageal Cancer Multidisciplinary Team confirmed the diagnosis of mid-thoracic ESCC at stage T4bN2M1 according to the AJCC(The American Joint Committee on Cancer, AJCC) 8th edition criteria based on further examinations. Following a multidisciplinary approach encompassing digital amputation, immunochemotherapy, and localized radiotherapy to the primary lesion, the disease achieved partial response according to RECIST(Response Evaluation Criteria in Solid Tumors, RECIST) 1.1 criteria.This case highlights the diagnostic challenges of rare metastatic presentations in ESCC, and the critical importance of recognizing atypical symptoms in high-risk populations. Early multidisciplinary intervention may improve outcomes in rare oligometastatic disease.
