Exercise in patients with advanced non-small cell lung cancer (NSCLC): Compliance and population characteristics of patients referred to the McGill Cancer Nutrition-Rehabilitation Program (CNRP)
Bibliographic record
Abstract
8631 Background: Few studies focus on exercise in advanced NSCLC. We evaluated compliance with exercise prescription in stages 3/4 NSCLC. Methods: Patients (pts) referred to the CNRP, a multidisciplinary clinic, for weight/functional loss were evaluated for participation in a supervised exercise program. Compliance with exercise was scored as 0 (refused/home exercise), 1 (<6 sessions in 2 mo), and 2 (≥ 6 sessions in 2 mo). Gender, age, PS, stage, CRP, weight loss, and quality of life [Edmonton Syptom Assessment Scale (ESAS)] were assessed by univariate and multivariate analyses. Survival from the time of exercise prescription was calculated using the Kaplan-Meier method and compared using the log-rank test. Results: 168 pts were referred to the CNRP from April 2002 to September 2005. 92/168 (54%) were prescribed exercise. Of the 76 remaining pts, 3 (4%) refused, and 6 (8%) were on an exercise trial. Others were excluded due to bone metastasis/severe pain (50 pts, 66%), cardiovascular instability (13 pts, 17%) or poor PS (4 pts, 5%). Of the 92 who were prescribed exercise, the compliance score was 0 in 38 (41%), 1 in 37 (40%) and 2 in 17(19%). There were no significant differences in gender, age, PS, stage, ESAS, and weight loss at the time of referral among the three compliance groups. Most pts (15/17) with a compliance score of 2 were referred prior to or during initial treatment, whereas those with compliance scores of 0 and 1 were referred later in the course of treatment. Compliance with exercise correlated with survival (p<0.001). The median survival from time of exercise prescription for pts with a compliance score of 2 was 22 mo (95%CI 13.4,30.2); compared with 5 mo (95%CI 3.7,5.6) and 7 mo (95%CI 2.5,11.5) for those with compliance scores of 0 and 1 respectively. No serious adverse events occurred. Conclusion: A select group of advanced NSCLC pts can exercise safely at a moderate-high level. Those referred earlier tended to be more compliant, and their longer survival may reflect a lead time bias. Clinical trials are needed to evaluate efficacy of exercise in newly diagnosed NSCLC. No significant financial relationships to disclose.

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.
