The Morphologic Spectrum of Mediastinal Yolk Sac Tumors: Diagnostic Challenges and Pitfalls.
Review in Cancers, 2026. 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
Pure mediastinal yolk sac tumor is an uncommon and aggressive malignant germ cell neoplasm that presents considerable diagnostic difficulties owing to its pronounced clinical and morphological variability. Mediastinal yolk sac tumors, in contrast to their gonadal equivalents, typically occur at later stages, are typically associated with mixed germ cell components, and have a diverse array of histologic patterns that may resemble both germ cell and somatic malignancies. Accurate identification of these types of cancer is essential since diagnostic misclassification may significantly impact treatment and prognosis. This review provides a comprehensive overview of the morphologic spectrum of mediastinal yolk sac tumor, with emphasis on both classic and variant histologic patterns, including reticular, solid, glandular, papillary, hepatoid, and other less common growth forms. The immunohistochemical correlations of these patterns and their role in resolving diagnostic dilemmas are discussed, along with key differential diagnoses encountered in small mediastinal biopsy specimens. Particular attention is given to the limitations of limited tissue sampling, the impact of post-chemotherapy morphologic changes, and the potential for misinterpretation in this challenging anatomic site. By integrating morphologic features with clinical, radiologic, and laboratory findings, this review aims to enhance diagnostic accuracy and improve recognition of mediastinal yolk sac tumor across its diverse presentations.
