A Rare but Lethal Malignant Cardiac Mass
Bibliographic record
Abstract
Primary cardiac tumors are extremely rare. Incidence is approximately 0.017% of all primary tumors. Spindle cell sarcoma is the rarest, with only four cases reported and there are no guidelines for treating this condition. Cardiac sarcomas have symptoms by different mechanisms including obstruction, local invasion, and embolisms and in some cases the first manifestation could be a sudden cardiac death. Diagnosis is made with imaging techniques such as echocardiogram, cardiac computed tomography (CT), and magnetic resonance imaging (MRI) and confirmed with tissue biopsy. Patients with malignant tumors have a poor prognosis with an average mean survival of 6 months. Complete resection of the tumor remains the best treatment available. Spindle cell sarcoma may present with few symptoms and may remain silent until an advanced stage, thus limiting the few therapeutic options available.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
