Effects of whole brain radiation on blood counts
Bibliographic record
Abstract
Background: Whole brain radiation therapy is commonly used in the treatment of patients with CNS metastatic disease. Radiation to other areas of the body is associated with decrease in bone marrow proliferation. It is unclear what the effects ofWBRT have on blood counts. Methods: Retrospective chart review of patients with brain metastases treated with WBRT with recorded hematologic valuesbefore and after treatment. Univariate analysis was performed to identify statistical differences in outcome via paired t -testing. Results: Forty-nine patients were analyzed. Median age was 61 and 36 subjects were female. Analysis revealed significantly amedian decrease of 0.87 g/dL in hemoglobin values ( p < .01) and 34 in platelet counts ( p < .01) after treatment, but no significantdecrease in WBC values ( p > .05). Conclusion: WBRT leads to a decrease in Hgb and platelets but does not appear to affect WBC counts. Physicians and patientsshould be aware of this side effect of WBRT.KeyWords: Whole brain radiotherapy, Anemia, Metastatic brain cancer

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.
