Treatment of elderly patients with acute lymphoblastic leukaemia using a paediatric‐based protocol
Bibliographic record
Abstract
All newly diagnosed patients aged 60-79 years with acute lymphoblastic leukaemia (ALL) receiving induction chemotherapy with a modified paediatric-based regimen over a 7-year period were retrospectively analysed (n = 51, median age 65 years). The treatment regimen consisted of induction, central nervous system prophylaxis, seven cycles of intensification and 24 cycles of maintenance. BCR-ABL1 negative patients received weekly asparaginase during intensification, while BCR-ABL1+ patients received daily imatinib. Post-remission therapy was given in an outpatient setting. The complete response rate was 75%, with an induction mortality of 20%; 6% of patients had resistant disease. 37% of patients who achieved a complete remission relapsed. The estimated 5-year overall survival was 40% for BCR-ABL1 negative and 47% for BCR-ABL1+ patients (P = not significant); the 5-year disease-free survival was 57% and 39%, respectively (P = NS). The post-induction phase was generally well tolerated, with 81% able to complete the intensification phase and proceed to maintenance. In conclusion, administration of this modified paediatric-based protocol is feasible and active for elderly patients with ALL. Survival is superior to most previously reported series in this age group, but remains worse compared to younger patients. Further improvement of the toxicity profile, particularly during induction, is required to improve outcomes.

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.
