Abstract
Matrix metalloproteinases (MMPs) are enzymes thought to be involved in tumor invasion. We hypothesized that MMP-2 and MMP-11 overexpression was associated with the aggressiveness of ovarian carcinoma. This study was performed on samples from 100 patients with stage III ovarian carcinomas treated surgically between 1990 and 2000. Immunohistochemical staining was performed on ovarian tumors and peritoneal implants using monoclonal antibodies. Overexpression was defined as more than 10% of cells expressing the marker. Multivariate analyses showed that only MMP-2 overexpression by cancer cells in peritoneal implants was associated with a significant risk of death by disease (hazard ratio, 2.65; 95% confidence interval, 1.41-4.97; P =.003). MMP-11 overexpression was not predictive of survival. These results suggest that MMP-2 overexpression by cancer cells in peritoneal implants and not in the primary ovarian cancer is predictive of ovarian cancer prognosis and more likely reflects the presence of particularly aggressive clones of cancer cells.

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 it
