Allogeneic haematopoietic stem‐cell transplantation for relapsed and refractory aggressive histology non‐Hodgkin lymphoma*
Bibliographic record
Abstract
Forty-four patients with relapsed or refractory aggressive histology non-Hodgkin lymphoma (NHL) (diffuse large B cell, n = 23; peripheral T cell, n = 5; transformed B cell, n = 16) proceeded to allogeneic stem cell transplant (allo-SCT) between 1987 and 2003. Median age at transplant was 40 years (range 19-56 years). At the time of transplant, 35 were chemosensitive and nine were chemorefractory. Thirty-three patients had matched sibling donors and 11 had unrelated donors. Forty-two patients (95%) received radiation-based conditioning regimens. Event-free survival (EFS) and overall survival (OS) at 5 years was 43% [95% confidence interval (CI): 27-58%] and 48% (95% CI: 32-63%) respectively. Treatment-related mortality was 25% at 1 year. Grade III-IV acute graft-versus-host disease (GVHD) was the only significant variable affecting OS and EFS, and had a negative impact. Chronic GVHD did not influence survival. Lymphoma relapse <12 months after initial therapy predicted for increased risk of relapse post-transplant (P = 0.02). Patients with chemorefractory lymphoma were not at increased risk of relapse (P = 0.20) with four of nine patients remaining alive without disease 12-103 months post-transplant. In conclusion, allo-SCT for relapsed or refractory aggressive histology NHL results in long-term EFS and OS of 40-50%. Patients with chemorefractory disease can have a durable remission post-transplant.

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.
