A Single‐Center Study on Frontline Treatment for Multiple Myeloma Patients With 1q Abnormalities
Bibliographic record
Abstract
ABSTRACT Introduction Chromosome 1q copy gains (with‐1q‐gain) is a frequently observed genetic abnormality in multiple myeloma (MM) patients. Recent research has demonstrated that 1q gain is a prognostic factor, linked to poorer clinical outcomes. Methods This study was conducted at the Princess Margaret Cancer Centre to examine the clinical outcomes of newly diagnosed MM patients’ with‐1q‐gain or without‐1q‐gain abnormality. The study included 275 patients, with 161 (58.5%) with‐1q‐gain abnormality. The median follow‐up time for the cohort was 94.3 months (95% CI 30.1–38.6). Results The patients’ with‐1q‐gain when compared to without‐1q‐gain were more likely to have other high‐risk cytogenetic abnormalities (34.8% vs. 14.0%, p < 0.001) and more advanced disease according to the International Staging System (ISS III, p < 0.014). Furthermore, a relatively higher proportion of with‐1q‐gain patients received tandem autologous stem cell transplant (ASCT) as frontline therapy (36.2% vs. 8.7%, p ≤ 0.001). To assess the impact of 1q copy number, patients with 3 copies of 1q (1q‐gain3) were compared to those with ≥4 copies (1q‐Amp). No significant differences were observed between the two groups. Conclusion In conclusion, our study provides insight into the clinical significance of 1q gain abnormality in MM patients at a single center, and highlights its association with adverse prognostic features and treatment 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.
