Expression of p53 in Inverted Papilloma and Malignancy Associated with Inverted Papilloma
Bibliographic record
Abstract
OBJECTIVE: To determine the association of p53 protein in malignant cases of inverted papilloma compared with cases of benign inverted papilloma of the sinonasal tract. DESIGN: Case-control study of archived pathologic material. SETTING: Tertiary care hospital. METHODS: Archived pathologic material of cases of malignancy associated with inverted papilloma and controls of benign inverted papilloma were obtained from Mount Sinai Hospital. These were subjected to immunohistochemistry for p53. Clinical correlation was obtained by retrospective chart review. MAIN OUTCOME MEASURES: Staining of pathologic specimens for p53 and survival or recurrence. RESULTS: Four of the five cases of malignancy associated with inverted papilloma demonstrated overexpression of p53. None of the benign cases of inverted papilloma demonstrated overexpression. Only two of the five patients with malignancy associated with inverted papilloma were alive at 2 years. CONCLUSIONS: Overexpression of p53 may serve as a marker for malignant transformation of inverted papilloma.

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.
