Isolated Renal Relapse in a Post-Allogenic Transplant Adult Patient With Acute Lymphoblastic Leukemia
Bibliographic record
Abstract
Acute lymphoblastic leukemia (ALL) is an aggressive hematological neoplasm typically more common in children than adults. More prolonged remissions and a potential cure can be achieved if allogeneic hematopoietic stem cell transplantation (allo-HSCT) is performed. Outcomes after allo-HSCT vary significantly among patients, and multiple factors contribute to these outcomes. Isolated extramedullary relapse (iEMR) after allo-HSCT is rare. We present the case of a 43-year-old man who was diagnosed with Philadelphia chromosome-negative (Ph-neg), B-cell ALL and underwent haploidentical allo-HSCT because of high-risk features at diagnosis. One year later, he was admitted to the hospital with facial and peripheral edema, proteinuria, elevated serum creatinine levels, and hypertension. Renal biopsy was performed immediately. Renal infiltration of TdT+ leukemic cells was detected by immunohistochemistry. Bone marrow aspiration, lumbar puncture, and computed tomography (CT) scans were performed to identify other sites of possible relapse. No other sites were identified, and an extramedullary isolated renal relapse was diagnosed. Intensive re-induction with chemotherapy was not possible because of the coronavirus disease 2019 (COVID-19) infection. Six weeks later, a medullary relapse was noted. Medullary infiltration of B-cell ALL after allo-HSCT has a historically poor prognosis; however, iEMR appears to have a better overall prognosis. The optimal treatment for renal iEMR is still a matter of debate.

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.
