A Rare Case of Severe Lactic Acidosis from 5-Fluorouracil after mFOLFOX6 Treatment in a Patient with Advanced Gastric Cancer
Bibliographic record
Abstract
Gastric cancer is one of the most common cancers worldwide and is one of the deadliest types of neoplasm. Many patients present with an advanced stage where palliative chemotherapy is the standard of care. 5-Fluorouracil (5-FU) remains the backbone of systemic therapy treatment in advanced gastric cancer, although is associated with many side effects. While cases of encephalopathy caused by hyperammonemia have been reported, lactic acidosis after systemic 5-FU exposure is exceedingly rare. We present here for the first time a case of type B lactic acidosis secondary to mFOLFOX6 therapy in advanced gastric cancer. This patient presented with acute delirium, dystonia, and a lactate of 11.7 mmol/L, which peaked to 18.7 mmol/L, within 48 h of chemotherapy treatment. Routine clinical monitoring of lactate may be beneficial to avoid this potentially life-threatening adverse event.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
