Correlation between Campanacci’s radiological classification of giant cell tumor of bone and expression of Cyclin D1 and PCNA
Bibliographic record
Abstract
Giant cell tumor of bone is considered by his behavior a benign but aggressive neoplasm. The objective of our study was to determine if there is a correlation between the Campanacci’s radiological classification of giant cell tumors of bone and the expression by immunohistochemistry of Cyclin D1 and proliferation cell nuclear antibody (PCNA). A retrospective and descriptive study was made. In total, there were 27 cases. All cases showed Cyclin D1 and PCNA positivity. Rho Spearman for Campanacci and Cyclin D1 expression was 0.06 and for Campanacci and PCNA was 0.418. We conclude that there is a positive correlation between PCNA expression in giant cell tumors of Bone and the Campanacci’s radiological classification II and III, butCyclin D1 expression was no related with radiologic features.

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.
