    • Abstract

    Background
    The impact of a systematic use of a Comprehensive Geriatric Assessment (CGA) on management strategies in elderly patients with no small cell lung cancer (NSCLC) is not well established. The objective of this study was to analyze if items of CGA may predict overall survival of elderly patients with NSCLC treated by chemotherapy or erlotinib in first or second lines setting.

    Methods
    Individuals data’s of GFPC 0504 study (population of fit elderly patients) and GFPC 0505 study (population of frail elderly patients) were pooled. The aim of these two prospective phase 2 trials were to compare a strategy using chemotherapy (doublet in fit patients, monotherapy in frail patients) in first line followed by erlotinib in second line to the reverse strategy (erlotinib in first line, followed by chemotherapy), in terms of progression-free survival (PFS) in second line period. Secondary outcomes were to compare first-line PFS, overall survival (OS), tolerance and costs. All patients had a complete comprehensive geriatric assessment, evaluating diverse areas as functional status, nutritional status, cognition, psychological functioning, and social support, at randomization. Predictive factors associated with OS were searched using Kaplan-Meier curves and logrank tests in the univariate analysis. A Cox model was used for the multivariate analysis.

    Results
    195 patients were included. Mean age was 77 years. 135 (70%) patients were males, 172 (89%) were stage IV and 109 (56%) were no or ex-smokers. At CGA assessment, 176 patients (70%) had an IADLD score of 3 or 4, 129 pts (66%) had a 0 or 1Charlson score, 167 pts (86%) had a simplified Charlson score < 8, 19 pts had a MMS score < 30, 146 pts (75%) had a situational score >10, 33 (17%) had a nutritional score <8. Factors predicting OS in the univariate analysis were 1-3 PS scores (1.5 [1.1 – 2.0], p=0.01); no or ex-smoker (0.70 [0.52–0.95], p = 0.02); 2-4 Charlson score (2.0 [1.4 – 2.7], p<0.0001, Simplified Charlson score ≥ 8 (1.50 [1.10–2.07],p=0.03), nutritional score>8 (0.60 [0.42 – 0.91], p= 0.01); 2 level mobility score (0.15 [0.04 – 0.62], p = 0.009). In the multivariate analysis, remained 1-3 PS (1.4 [1.02 – 1.9], p = 0.04), 2-4 Charlson score (1.46 [1.07 – 1.99], p=0.02), >8 nutritional score (0.69 [0.46 – 1.04], p= 0.07), level 2 mobility score level (0.25 [0.06 – 1.01], p = 0.06)

    Conclusion
    Comorbidities, nutritional and mobility scores, in this specific elderly population are predictive of OS. Prospective studies using large prospective cohort are needed to better select the more relevant management for elderly with advance NSCLC.
