Gastric metastases from primary breast cancers: rare causes of common gastrointestinal disorders
Bibliographic record
Abstract
We report two cases of gastric metastases from primary breast cancers. In case 1, a 31-year-old woman with right-sided ductal breast carcinoma presented with nausea, vomiting and frank haematemesis, 8 months after mastectomy and adjuvant chemotherapy. An esophagogastroduodenoscopy (EGD) revealed multiple ulcerated gastric lesions secondary to metastatic adenocarcinoma from primary breast tumour. In case 2, an 84-year-old woman with a history of left lobular carcinoma presented with early satiety, 17 years after initial mastectomy and adjuvant endocrine therapy. An EGD revealed unspecific gastric mucosa with thickened and erythematous folds and biopsies revealed adenocarcinoma from primary breast carcinoma. Our cases demonstrate how gastric metastases have variable, non-specific clinical and endoscopic presentations. Symptoms may include nausea, vomiting, early satiety and gastrointestinal (GI) bleeding. Endoscopic appearance may range from thickened gastric folds to ulcerating lesions. Our cases demonstrate that gastric metastases should be considered in patients with breast cancer history presenting with GI symptoms.

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.
