Abstract

fetched live from OpenAlex

A 62-year-old woman presented to our institution with a 3-year history of left-sided breast mass. Diagnostic imaging three years prior suggested the presence of a lipoma with no suspicious findings. The patient noted that the mass continued to grow with no significant clinical symptoms. Imaging revealed a substantial difference in breast size, with the left breast largely occupied by a fatty vascular soft tissue mass. The patient was diagnosed with liposarcoma arising from or infiltrating the pectoralis major and minor muscles. The patient underwent a mastectomy, and the final pathology results confirmed an atypical lipomatous tumour with well-differentiated liposarcoma components. Liposarcoma should be considered and ruled out in cases of any large or growing fatty masses in the breast.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
