Abstract
The rates of cell proliferation and programmed cell death (apoptosis) reflect tumor cell dynamics and are considered to directly influence biological progression and tumor response to therapy. Bax and Bcl-2 are members of a gene family that influence apoptosis and have been used as surrogate markers in the evaluation of this process. Sixty-three fine-needle tumor samples from an equal number of patients with breast carcinomas were analyzed for Bax, Bcl-2, and DNA content by flow cytometry. The results were correlated with classical clinicopathological parameters. Bax values varied widely among tumors and showed no significant correlation with any of the clinicopathological parameters analyzed. Bcl-2 levels ranged from 4% to 91%, correlated positively with estrogen (P = 0.0004) and progesterone (P = 0.0045) receptor positivity, and were more associated with low S-phase tumor values. In contrast, high S-phase values correlated with estrogen receptor negativity, high grade, and DNA aneuploidy. The study results indicate that Bcl-2 and S-phase analysis of fine-needle samples of breast carcinomas provide a convenient tool for the assessment of these tumors.

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
