Incidence and Risk Factors for Early Hepatotoxicity and Its Impact on Survival in Patients with Myelofibrosis Undergoing Allogeneic Hematopoietic Cell Transplantation
Bibliographic record
Abstract
Allogeneic hematopoietic cell transplantation (HCT) is commonly associated with hepatic complications. Patients with myelofibrosis (MF) often develop liver dysfunction in the early posttransplantation period; however, this has not yet been studied in a systematic fashion. We retrospectively evaluated 53 patients with MF who underwent HCT to assess the prevalence of acute liver toxicity and risk factors and the impact on survival. We compared the prevalence of acute hepatic complications in that group and a matched control group of 53 patients with myelodysplastic syndrome (MDS). In the MF group, during the first 6 weeks after HCT, the incidence of mild (34.2-102.6 μM), moderate (102.6-342 μM), and severe (>342 μM) hyperbilirubinemia was 34%, 40%, and 4%, respectively (normal, <22 μM). The incidence of mild/moderate transaminitis (2-10 times the upper limit of normal) was 23%, and that of severe transaminitis (>10 times the upper limit of normal) was 6%. Veno-occlusive disease as defined by the Baltimore criteria was observed in 19 patients (36%) in the MF group. Compared with MDS, MF was associated with a significantly higher incidence of moderate/severe hyperbilirubinemia (44% versus 21%; P = .02) and veno-occlusive disease (36% versus 19%; P = .05). A history of portal hypertension, biopsy-proven hepatic iron overload, or splanchnic vein thrombosis was a strong predictor of moderate/severe hyperbilirubinemia (P = .02). Acute hepatocellular injury with moderate/severe hyperbilirubinemia or transaminitis was associated with inferior survival at 12 months (P = .02) in the MF group. We conclude that patients with MF are at significant risk of early hepatotoxicity after HCT, which is associated with an adverse impact on survival.

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.
