Newly diagnosed multiple myeloma patients treated with tandem auto‐allogeneic stem cell transplant have better overall survival with similar outcomes at time of relapse compared to patients who received autologous transplant only
Bibliographic record
Abstract
BACKGROUND: Long-term survival in patients progressing after tandem autologous-allogeneic stem cell transplant (SCT) has been reported, suggesting a persistent graft-vs-myeloma (GvM) effect even after post-transplant progression. METHODS: In order to confirm this observation, we updated the results of our previously published cohort of 92 newly diagnosed myeloma patients who received tandem transplant and compared them with 81 contemporary patients who received autologous transplant only. RESULTS: With a median follow-up of 13.1 and 10.2 years, respectively, median overall survival (OS) in the tandem group has not been reached, compared with 6.1 years after auto-SCT (P ≤ .001). Disease progression occurred less frequently after tandem transplant, with an estimated 10-year cumulative incidence of 49% vs 76% (P ≤ .001). Cumulative incidence of extensive chronic graft-vs-host disease (cGVHD) was high at 83%, with modest benefits on OS (60% vs 49%, P = .550) but sharp improvement of progression-free survival (PFS; 55% vs 10%, P = .002) at 10 years associated with development of cGVHD. After first progression, median OS was 5.8 years in tandem and 5.2 years in the auto-group (P = .062); median PFS was also similar. CONCLUSION: Despite confirmation of better outcomes after upfront tandem transplant, our data do not support persistence of a strong, clinically significant graft-vs-myeloma effect after first progression, emphasizing the need to better characterize the GvM effect.

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.
