Pediatric Alpha-Fetoprotein-Producing Gastric Cancer Presenting With Dysphagia and Multiple Liver Tumors.

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
backgroundAlpha-fetoprotein (AFP)-producing gastric cancer (AFPGC) is resistant to chemotherapy and is associated with poor prognosis. Pediatric gastric cancer has an incidence of 0.02% among gastric cancer patients, with a median survival of 5 months. CASE: A 13-year-old boy presented with progressive dysphagia for 2 months, accompanied by loss of appetite and significant weight loss. Liver dysfunction and multiple lesions were observed. Laboratory investigations revealed elevated liver enzymes and tumor markers, including AFP, at 24 502 ng/mL. Computed tomography (CT) showed thickening of the gastric cardia and multiple liver lesions. Upper gastrointestinal endoscopy revealed a type 2 tumor in the cardia. Histopathology confirmed adenocarcinoma, and immunohistochemical staining was positive for AFP, establishing a diagnosis of AFPGC with liver metastases (Stage IV). Given the unresectable and HER2-negative nature of the cancer, chemotherapy with TS-1 and cisplatin was initiated, resulting in a temporary reduction in AFP levels and tumor size. However, disease progression was noted after 3 months, requiring a switch in treatment to ramucirumab, paclitaxel, bleomycin, etoposide, cisplatin, or a study drug. Despite these efforts, the patient succumbed to the disease 16 months after initial treatment.
conclusionAFPGC in children is extremely rare, with few reported cases. The 16-month survival observed in this case exceeds previously reported durations (8 and 4 months). Systematic evaluation of persistent gastrointestinal symptoms enabled earlier diagnosis. Standard adult gastric cancer treatment protocols appeared more effective than AFP-tumor-specific regimens, suggesting they may be optimal for pediatric AFPGC as well. Early diagnosis through detailed history-taking and prompt endoscopic examinations in children with gastrointestinal symptoms may lead to significantly prolonged survival and improved management in this rare malignancy.
