Primary orbital mesenchymal chondrosarcoma: clinicopathological characteristics and prognostic prediction
Bibliographic record
Abstract
OBJECTIVE: This study aimed to analyze the clinicopathological characteristics of a rare malignant tumour, primary orbital mesenchymal chondrosarcoma (MCS), and identify the risk factors influencing its prognosis. METHODS: A total of 15 patients with histologically confirmed primary orbital MCS were enrolled between April 2013 and October 2022. The relationships between clinicopathological features and outcomes, including recurrence and survival were analyzed. RESULTS: During the follow-up period, 9 patients (60%) experienced disease relapse, and 7 patients (46.7%) succumbed to the disease. Immunohistochemical analysis showed positive rates for SMA, CD-99, S-100, vimentin, and Bcl-2 at 60%, 60%, 53.3%, 100%, and 93.3%, respectively. The Ki67 index was positively associated with the recurrence and mortality rates. CONCLUSION: Our study suggested that the Ki67 index could be a vital prognostic factor for MCS. Further follow-up studies are required to assess the efficacy of chemotherapy and radiotherapy in improving patient outcomes.

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.
