Cyto‐histological correlations inprimary, recurrent, and metastatic bone and soft tissue osteosarcoma. Institut Curie's experience
Bibliographic record
Abstract
To determine diagnostic cytomorphologic features of osteosarcoma on fine-needle aspiration materials, we reviewed the cytologic material and corresponding histologic slides of 126 tumors in 107 patients. Fifty-five (43.6%) tumors were primary, 31 (24.6%) were recurrent, and 40 (31.8%) were metastatic. Review of original cytology reports revealed that 120 (95.3%) tumors were diagnosed as malignant. Six (4.7%) cases were reported as suspicious, false-negative, or unsatisfactory samples. Our findings showed that osteoblastic roundish cells, spindle-shaped cells, reactive giant cells, and osteoid were the most consistent features representative of osteosarcoma. Periosteal reactions, fractures with callous formation, giant cells of osteoclastic type in various conditions, chondrosarcoma with enchondral ossification are entities to consider in the differential diagnosis.

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.
