Metastatic pancreatic cancer with complete response to FOLFIRINOX treatment
Bibliographic record
Abstract
A 59-year-old woman presented with abdominal pain associated with nausea and night sweats. A large mass was found in the pancreatic tail and innumerable liver lesions were identified. Ultrasound-guided biopsy of a liver nodule confirmed moderately differentiated adenocarcinoma consistent with a pancreatobiliary primary. On FOLFIRINOX chemotherapy, subsequent CT scans showed shrinkage of the pancreatic mass and liver metastases. Her cancer antigen 19-9 (CA 19-9) normalised after 11 months. Oxaliplatin was discontinued due to peripheral neuropathy but she completed 37 cycles of FOLFIRI during which her pancreatic mass disappeared, liver lesions decreased in size and were subsequently deemed to be scar tissue by the radiologist. After 4 years of treatment, the patient agreed to a break from chemotherapy. Eighteen months afterwards, an MRI abdomen continues to demonstrate no visible pancreatic mass and the two remaining liver lesions, believed to be scar tissue, remain stable. Her CA 19-9 level remains normal. This appears to be a complete response to FOLFIRINOX/FOLFIRI chemotherapy in a patient with metastatic pancreatic cancer.

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.
