The Effect of Lenalidomide on Health-Related Quality of Life in Patients With Lower-Risk Non-del(5q) Myelodysplastic Syndromes: Results From the MDS-005 Study
Bibliographic record
Abstract
BACKGROUND: The phase III MDS-005 study compared lenalidomide versus placebo in red blood cell transfusion-dependent (RBC-TD) patients with lower-risk non-del(5q) myelodysplastic syndromes (MDS), ineligible/refractory to erythropoiesis-stimulating agents. Lenalidomide-treated patients were more likely to achieve transfusion independence (TI) ≥ 8 weeks (26.9% vs. 2.5%; P < .001) and hemoglobin increase ≥ 1.5 g/dL (19.4% vs. 2.5%) versus placebo. PATIENTS AND METHODS: Patients were randomized 2:1 to oral lenalidomide 10 mg once daily or placebo once daily (both on 28-day cycles). Patients with creatinine clearance 40 to 60 mL/min were given lenalidomide 5 mg once daily. Health-related quality of life (HRQoL), a predefined secondary end point, was assessed using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 questionnaire at baseline, week 12, week 24, every 12 weeks thereafter, and at discontinuation. RESULTS: At week 24, lenalidomide was associated with benefit versus placebo across all 5 preselected questionnaire scales (fatigue, dyspnea, global quality of life, physical functioning, and emotional functioning). After adjustment for baseline scores, only emotional functioning achieved significance (P = .047). Further improvement versus baseline was observed for patients who continued lenalidomide after week 24. In post hoc analyses, achievement of TI ≥ 8 weeks was associated with significant improvements across all scales (P < .01); an increase in hemoglobin level correlated with significant improvements in all scales at week 24, except emotional functioning (P < .05). CONCLUSION: Lenalidomide did not adversely affect HRQoL in RBC-TD patients with lower-risk non-del(5q) MDS and response to lenalidomide was associated with significant improvements in HRQoL.

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.
