Metastatic Chondroblastic Osteosarcoma Involving the Thoracic Aorta Managed with Thoracic Endovascular Aortic Repair: A Case Report and Tribute.
Article in Vascular specialist international, 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
Chondroblastic osteosarcoma is a rare and aggressive subtype of osteosarcoma, and thoracic aortic involvement is exceptionally uncommon. We report a 57-year-old male with multifocal metastatic chondroblastic osteosarcoma presenting as a mediastinal mass encasing the descending thoracic aorta. He presented with painful thigh swellings, fatigue, and weight loss for three weeks. His history included right orchidectomy and chemotherapy for a germ cell tumor 30 years earlier, with remission. Biopsy of the thigh lesions confirmed metastatic chondroblastic osteosarcoma. Staging computed tomography revealed an unresectable mediastinal mass encasing the descending thoracic aorta, with intraluminal thrombus causing near-total occlusion. Positron emission tomography-computed tomography demonstrated avidity involving the mediastinal mass and partial uptake in the thrombus. Thoracic endovascular aortic repair relieved the stenosis and enabled systemic therapy. Despite systemic and palliative therapies, the patient succumbed to progressive disease 13 months after diagnosis. This case highlights the role of endovascular repair in malignant aortic involvement.
