Concurrent Splenic and Right Atrial Mass at Presentation in Dogs with HSA: A Retrospective Study
Bibliographic record
Abstract
The objective of this retrospective study was to evaluate the presence of concurrent splenic and cardiac hemangiosarcoma (HSA). Dogs were divided into two groups: group 1 included 23 dogs with splenic HSA, and group 2 included 31 dogs with a cardiac HSA. All dogs were fully assessed for metastasis with thoracic radiography, abdominal and/or cardiac ultrasound, and/or postmortem examination. Two dogs (8.7%) in group 1 had a concurrent cardiac mass. Neither of these dogs had pericardial effusion, and both were golden retrievers. Thirteen of the dogs in group 1 presented with a hemoabdomen. Concurrent intra-abdominal metastasis was noted in seven dogs. In group 2, 9/31 (29%) of the dogs had a concurrent splenic HSA, and 13/31 (42%) of the dogs had evidence of metastasis to another site. There was a significant association between age and the presence of nonsplenic metastasis (odds ratio, 0.457). The rate of concurrent right atrial mass detected by cardiac ultrasound in dogs with splenic HSA was 8.7%, which is less than previously reported. For dogs with right atrial HSA, the risk of metastasis to nonsplenic sites decreases with age.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
