Abstract
BACKGROUND: Sentinel lymph node biopsy (SNB) is rapidly gaining acceptance as an alternative to axillary dissection (AD) in patients with early breast cancer. Debate continues regarding the optimum technique for sentinel node (SN) mapping. We have used our series of 364 SNBs to compare two different techniques. METHODS: A retrospective review of patients undergoing SNB by surgeons in our breast service. Overall results were analysed, with particular attention to those having blue dye alone and those having blue dye in combination with radio-labelled colloid. SNs were analysed using haematoxylin-eosin and immunohistochemical staining. RESULTS: SN identification rates were similar: 96% for dye alone and 89% for dye and colloid in combination. Twenty-one per cent of SN mapped with dye alone contained metastases, compared to 30% with dye and colloid in combination. The false-negative rate was correspondingly higher in the dye alone group (21 vs 2.8%). CONCLUSION: SNB using dye and colloid in combination was significantly superior to dye alone in this series. We advocate using both dye and colloid for intraoperative SN mapping.

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
