Outcomes of older patients (≥60 years) with acquired aplastic anaemia treated with immunosuppressive therapy
Bibliographic record
Abstract
We report a single center experience in treating 24 consecutive patients > or = 60 years old for aplastic anaemia (AA) with immunosuppressive therapy (IST). The main outcomes of interest were the tolerability and toxicity of IST, response rate and survival. Median age was 70 years (range 61-78). Seven patients received standard IST consisting of standard dose antithymocyteglobulin (ATG) with or without ciclosporin (CsA), and 17 patients received attenuated IST consisting of at least a 50% dose reduction of ATG with CsA or CsA alone. Six patients (25%) had early deaths, mostly due to infection. Early mortality appeared higher in the standard IST group although this was not statistically significant (43% vs. 18%, P = 0.4). The 2-year cumulative incidence of response was 42% [95% confidence interval (CI) 26-69%]. Responders had significantly better survival than non-responders (P = 0.0002). The 3-year probability of overall survival was 49% (95% CI 27-68%). Moderate or severe co-morbidities (P = 0.03) as determined by Charlson Co-morbidity Index and very severe AA (P = 0.007) were associated with significantly inferior overall survival while age was not. Nine out of 14 evaluable patients in the attenuated IST group had durable responses to treatment, suggesting that patients not suitable for standard IST can still benefit from attenuated IST.

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.
