Occult Primary Breast Cancer Presenting With Axillary Nodal Metastasis: Report of 3 Cases
Bibliographic record
Abstract
Occult primary breast cancer presenting as axillary metastasis is a very rare entity of breast cancer. Diagnosis and treatment management represent a real challenge in the absence of consensual attitude. We report 3 cases of occult breast cancer who presented with metastatic nodule in the axilla. Although histology identified a metastatic adenocarcinoma in the lymph nodes, mammography failed to detect the primary tumor. Immunohistochemistry showed that the biopsied lymph nodes were positive for both estrogen and progesterone receptors in all cases, suggesting the breast as the site of the primary tumor. Breast MRI was normal in addition to thoraco-abdomino-pelvic scan. Axillary dissection was performed with breast conservation followed by ipsilateral breast radiotherapy, then adjuvant chemotherapy. They are currently being treated with tamoxifen without evidence of disease with a median follow up of 8 months. doi: http://dx.doi.org/10.4021/jcgo42w

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.
