Bibliographic record
Abstract
63 Background: The correlation of radiological response and pt-reported outcomes (PROs) in advanced NSCLC remains underreported. This interim analysis evaluated QoL by response (RECIST v1.1) in SCC NSCLC pts treated with nab-P/C during the induction part of the ABOUND.sqm study. Methods: In the ongoing phase III ABOUND.sqm study, pts with advanced SCC NSCLC are treated with first-line nab-P 100 mg/m2 d 1, 8, 15 and C AUC 6 mg•min/mL d 1 (21-d cycles) for 4 cycles (induction). Pts not progressing are randomized 2:1 to maintenance nab-P 100 mg/m2d 1 and 8 of each 21-d cycle + best supportive care (BSC) or BSC alone until progression. The primary endpoint is PFS from randomization to maintenance. QoL, an exploratory endpoint, was assessed with predefined PRO instruments, LCSS and EQ-5D-5L, on d 1 of each cycle. Pts with a radiological CR/ PR are considered responders (R) in this analysis (57% of evaluable pts). As the study is ongoing, this pre-planned analysis included QoL and tumor response data that were reported up to the cutoff date. Results: Baseline (BL) characteristics were similar for Rs (n = 73) and non-Rs (n = 55). Over 80% of pts completed BL + ≥ 1 post-BL PRO assessments. For LCSS, average total score and symptom burden index improved during induction chemotherapy; a higher percentage of Rs vs non-Rs had clinically meaningful improvements (≥ 10 mm [VAS]) from BL in composite LCSS cough, shortness of breath, & hemoptysis (56% vs 38%). Of pts reporting BL EQ-5D-5L dimension problem(s), a higher percentage of Rs vs non-Rs reported complete resolution at least once during treatment (Table). Conclusions: These results indicate that Rs and non-Rs maintained/improved QoL during induction therapy with nab-P/C. Rs appeared to have greater improvements in LCSS and EQ-5D-5L. Radiological response translates into meaningful QoL improvement. Clinical trial information: NCT02027428. [Table: see text]

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.
