Pure Primary Squamous Cell Carcinomas of the Breast: A Report of Eight Cases
Bibliographic record
Abstract
Pure primary squamous cell carcinoma (PPSCC) of the breast is a rare neoplasm included in World Health Organization Classification of tumors (2003) in metaplastic breast cancer. It accounts for less than 0.1% of all breast carcinomas. We performed a retrospective review of all women diagnosed or treated as PPSCC, from January 2004 to June 2009 to assess clinical presentation, surgical and pathological findings, treatment and outcome. Eight patients were identified. The median age was 48.2 (range: 40 - 57) years. The average tumor size was 7.3 cm, with a range of 3.5 to 18 cm. There were one well differentiated, three moderately differentiated and four poorly differentiated PPSCC. Two cases were stage IIA, two cases stage IIIA and three cases stage IIIB. Primary treatment was mastectomy in six patients and large local excision in one patient. There was lymph node (LN) involvement in one patient. Estrogen and progesterone receptors status and over expression of HER 2 were assessed and none tumors was positive. Cytokeratin 5/6 and/or Cytokeratin 14 were positive in all tumors. All patients were treated by radiotherapy and chemotherapy. Though PPSCC of the breast is a very rare and aggressive disease, in our experience it’s relatively frequent. Strict histologic criteria should be used to diagnose PPSCC, because they have significantly lower axillary lymph node metastasis, lower estrogen and PR positivity, and they are often treatment-refractory. The role of different new chemotherapy regimens needs to be explored. doi:10.4021/jmc2010.07.105e

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.
