Secretory Breast Carcinoma: Unique, Triple-Negative Carcinoma With a Favorable Prognosis and Characteristic Molecular Expression
Bibliographic record
Abstract
Secretory carcinoma is a rare but distinct subtype of breast carcinoma, with characteristic histomorphology and generally favorable prognosis. Although it was originally described as a juvenile breast carcinoma, occurring in young children, most cases have been reported in adults of both sexes. As the name implies, the characteristic histomorphology is the presence of a large amount of intracellular and extracellular, eosinophilic secretion material that stains positive for periodic acid-Schiff. Most tumors stain positive for S100 and negative for estrogen receptor, progesterone receptor, and ERBB2 (formerly HER2/neu) (ie, triple negative). In addition, some secretory carcinomas demonstrate a basal-like immunoprofile. Recent studies have shown the characteristic molecular feature: a balanced translocation t(12;15), resulting in an ETS variant 6-neurotrophic tyrosine kinase receptor type 3 (ETV6-NTRK3) fusion gene encoding a chimeric tyrosine kinase. Although rare events of axillary lymph node or distant metastases have been documented, the prognosis is generally excellent. The methods of surgical treatment and the role of adjuvant therapy, particularly for young patients, remain controversial.

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.
