Thymoma with Extensive Necrosis: A Case Report and Literature Review.
Article in Surgical case reports, 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
introductionThymomas are associated with necrosis and hemorrhage in approximately 5% of cases; however, cases in which necrotic tissue constitutes the majority of tumors are rare. CASE PRESENTATION: A 30-year-old man was referred to our hospital with transient anterior chest pain and a mediastinal mass detected on a health check-up. Positron emission tomography/computed tomography showed no fluorodeoxyglucose uptake, and serum and biochemical analyses revealed no elevated inflammatory responses or tumor marker levels. Based on imaging findings, thymic cysts and thymomas were considered differential diagnoses, and thoracoscopic mediastinal tumor resection was performed. The encapsulated tumor, which was adherent to the lung via the thickened pleura, was successfully resected, and a rapid diagnosis of thymoma was made. Final pathological examination confirmed a type B2 thymoma, with necrosis comprising approximately 80% of the tumor. The patient has been followed up on an outpatient basis, with no recurrence at 1 year after surgery.
conclusionsExtensive necrosis in thymic tumors often suggests high-grade malignancy, but may also occur in necrotic thymoma with a favorable prognosis. Recognizing this possibility is essential to avoid overtreatment and guide appropriate surgical management.
