Osteopontin (OPN) expression in thyroid carcinoma.
Bibliographic record
Abstract
BACKGROUND: Osteopontin (OPN) and its interacting partner CEA-cell adhesion molecule (CEACAM1) mediate similar biological functions and have been expressed in several types of cancer. Here we investigated the prognostic significance of OPN in thyroid tumours and correlated our findings with the expression of CEACAM1. MATERIALS AND METHODS: 297 human thyroid samples were collected in a tissue microarray and as fresh frozen samples to perform immunohistochemistry and western blotting for OPN and to compare these data with our previously published data on CEACAM1 expression. RESULTS: Nearly all normal samples were negative for OPN. Some thyroid adenomas were weakly OPN positive whereas many carcinomas were strongly positive. In contrast to CEACAM1, which was preferentially expressed in metastatic papillary carcinomas, no associations were found between OPN expression and patient age, gender and tumour size. CONCLUSION: These results may have future implications for the diagnosis and management of patients with thyroid cancers.

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.
