A Comparative Study of Bcl-2 Expression in Oral Leukoplakia with Dysplasia, Verrucous Carcinoma, and Oral Squamous Cell Carcinoma
Bibliographic record
Abstract
Aim: To study the immunohistochemical expression of Bcl-2 in oral leukoplakia with dysplasia, verrucous carcinoma and oral squamous cell carcinoma(OSCC). Methodology: A total of 80 formalin-fixed , paraffin- embedded specimens were selected , amongst them 30 cases of different grades of dysplasia- 10 mild, 10 moderate and 10 severe and 30 oral squamous cell carcinoma of various grades- 10 well differentiated, 10 moderately differentiated and 10 poorly differentiated, 10 verrucous carcinoma had been included in the study. 10 normal buccal mucosa were used as control group. Results: The immunohistochemical expression of Bcl-2 in oral leukoplakia with different grades of dysplasia, in verrucous carcinoma and in different grades of oral squamous cell carcinoma with normal mucosa were compared. Moreover, the expression of Bcl-2 was found to increase significantly between dysplasia and different grades of oral squamous cell carcinoma. Conclusion: The expression of Bcl-2 has always guided the researchers towards mapping the progression of dysplasia as well as malignant transformation at the molecular level.

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.
