A Case of Breast Cancer Recurrence Mimicking a Thymus Tumor With Vascular Invasion.
Article in Cureus, 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
Mediastinal tumors have many differential diagnoses, making it challenging to confirm a diagnosis through imaging alone. We report a case of mediastinal recurrence of breast cancer mimicking a thymic tumor, with invasion of the left innominate vein, occurring 13 years post surgery. Given the tumor thrombus extending into the superior vena cava (SVC), surgical resection was performed to prevent life-threatening complications and to achieve definitive diagnosis and treatment. Breast cancer is known for its slow growth and late recurrence. While axillary lymph nodes (ALNs) are the most common site of breast cancer drainage, alternative pathways such as the internal mammary lymph nodes may also play a role in disease spread. Recurrence of breast cancer in IMLN can mimic mediastinal tumors, such as thymoma or thymic cancer. Therefore, in patients with a history of breast cancer, a mediastinal tumor should raise suspicion for breast cancer recurrence, even if it involves the innominate vein or occurs after a long interval.
