MA06.10 - A Pooled Analysis Comparing the Outcomes of Elderly to Younger Patients on NCTN Trials of Concurrent CCRT for Stage 3 NSCLC (ID 4219)
17:06 - 17:12 | Author(s): J. Schiller
- Abstract
- Presentation
Background:
Concurrent chemoradiotherapy (CCRT) is the standard treatment (TRT) for stage 3 NSCLC. Elderly patients (pts) are common, may have increased toxicity,& poorer results from CCRT
Methods:
Individual patient data (IPD) from NCTN phase 2/3 trials of CCRT for stage 3 NSCLC from 1990-2012 was collected. We compared the overall survival (OS), progression-free survival (PFS), & adverse events (AE’s) for pts age ≥70 years (yrs) (elderly) vs. <70 yrs (younger). Unadjusted & adjusted Hazard Ratios (HRs) for survival time & their confidence intervals (CIs) were estimated by single-predictor & multivariable Cox models. Unadjusted & adjusted Odds Ratio (OR) for AE’s & their CIs were obtained from single-predictor & multivariable logistic regression models
Results:
IPD from 16 trials were analyzed; 2,768 pts were younger & 832 were elderly. Median OS & PFS for elderly & younger pts are in the table. In the unadjusted & multivariable models elderly pts had worse OS (HR=1.23; 95%CI =1.13-1.35, and 1.20; 95%CI=1.10-1.32, respectively). In the unadjusted & multivariable models, elderly & younger pts had a similar PFS (HR=1.02; 95% CI=0.94-1.11 and 1.01, 95% CI=0.92-1.10, respectively). Elderly pts had a higher rate of grade ≥3 AE’s in the unadjusted & multivariable models (OR=1.25; 95% CI=1.00-1.57 and 1.30; 95%CI=1.03-1.62, respectively). A lower percentage of elderly pts compared to younger completed TRT (47% and 57%, respectively; P<0.0001) & higher percentage stopped due to AE’s (20% and 13%; P<0.0001). Grade ≥ 3 AE’s (occurring at a rate ≥ 2.5%) with a higher rate in the elderly: neutropenia, dyspnea, fatigue, anorexia, vomiting, dehydration, hypoxia, hypotension, & pneumonitis (P<0.05).
a: Log-rank test for survival times, chi-square test for AE’s, and Fisher’s exact test for deaths. The P-values from these tests are unadjusted. b: Data available on 2,091 patientsAge ≥ 70yrs Age < 70 yrs P-value[a] Median OS (months) 17.0 20.7 < 0.01 Median PFS (months) 8.7 9.1 0.68 All toxicities grade ≥3 86% 84% 0.04 Hematologic AE’s grade ≥3 65% 61% 0.04 Non-hematologic AE’s ≥3 68% 62% <0.01 Grade 5 AE’s 9.0% 4.4% <0.01 TRT related deaths[b] 3.2% 2.0% 0.12
Conclusion:
Elderly pts in CCRT trials had worse OS, similar PFS, & a higher rate of severe AE's.

OA04.02 - Smoking Behavior in Patients with Early Stage Non-Small Cell Lung Cancer: A Report from ECOG-ACRIN 1505 Trial (ID 5385)
11:10 - 11:20 | Author(s): J. Schiller
- Abstract
- Presentation
Background:
Approximately 85% of lung cancer is related to cigarette smoking. Smoking cessation has been reported to benefit patients even after the diagnosis of lung cancer. We studied the smoking behavior of patients with lung cancer in a phase 3 study for early stage lung cancer.
Methods:
The ECOG-ACRIN 1505 study enrolled patients with stages IB, II and IIIA non-small cell lung cancer (NSCLC) after they had undergone surgical resection. It was designed to evaluate whether the addition of bevacizumab would improve survival relative to cisplatin-based chemotherapy alone. Studying the correlation between smoking status and outcome was a secondary endpoint. Patients completed a questionnaire about their smoking habits at baseline, 3, 6, 9 and 12 months after study entry.
Results:
Out of 1501 patients enrolled, 99%, 90%, 85%, 82% and 80% responded to the questionnaire at baseline, 3, 6, 9 and 12 months respectively. Nearly 90% reported having smoking during their lifetime. At study entry, 12% reported ongoing smoking. The median age patients started smoking was 17 years and the median age at which they quit smoking was 55 years. The median number of cigarettes smoked per day was 20. Approximately 4% smoked cigars (median number 2/day). Of the 40% that reported smoking after the diagnosis of lung cancer, only 15% reported smoking at 12 months. At 12 months after study entry, among those who continued to smoke, 79% reported smoking fewer cigarettes/day, whereas 11% smoked more cigarettes. When asked about the number of cigarettes smoked at 12 mos, 63% reported smoking fewer than 10 cigarettes/day. The incidence of grades 3-5 toxicity was 76% in smokers versus 69% in non-smokers (p=0.06). There were no differences in dose reductions for chemotherapy (P=0.55) or bevacizumab (P=0.90) between smokers and non-smokers. The median number of chemotherapy cycles were nearly identical for smokers and never-smokers. The disease-free survival (DFS) and OS for smokers relative to never-smokers were 0.97 (P=0.83) and 1.54 (P=0.01) respectively.
Conclusion:
This is the first comprehensive, prospective report of smoking habits of patients with lung cancer. There were a high rate of smoking cessation and reduction in number of cigarettes smoked, that was maintained at 12m after study entry. Toxicity and DFS did not differ significantly between smokers and never-smokers, though overall survival was more favorable with the never-smokers. Study was coordinated by ECOG-ACRIN (Robert L. Comis, M.D., Chair) and supported in part by Public Health Service Grants CA180820, CA180888, CA180821, & CA180863.
