      • Abstract

      Background
      Few studies are dedicated to elderly patients with unresectable stage IIIA/B. We used a Standardized Geriatric Assessment (SGA) to select fit elderly patients and assess if this population can benefit from standard of care, namely concurrent CRT.

      Methods
      The aim of this multicentric phase II opened-study was to assess CRT in patients older 70 years with locally advanced NSCLC, evaluated as “fit” according to SGA.CRT associated oral vinorelbine (30 mg/m²/week) and IV cisplatinum (30 mg/m²/week) during 6 weeks concurrently with radiotherapy (66 Gy, 33 fractions, 6,5 weeks). Main inclusion criterias were : PS ≤ 1, weight loss < 10%, creatinine clearance ³ 50 ml/mn abreviated, VEMS ³ 40%, PaO2 ³ 60 mm Hg, KCO ³ 60% and patient classified as fit according to SGA. The principal end-point was early treatment tolerance (number of patients with adverse event grade ³ 3 (except nausea and vomiting) or grade 4 for hematologic toxicity and asthenia. Secondary end-points were RECIST response 4 weeks after treatment, quality of life, tolerance, progression-free survival and overall survival. Using a Simon's optimal plan in 2 steps, the total number of patients to be included was 59 with an intermediate analysis after 19 patients. Toxicities and serious adverse events were monitored by an independent peer committee.

      Results
      Interim analysis was done after 23 inclusions in 19 evaluable patients: males 84% , mean age 74.6 (70 to 83) years, 3 patients didn’t end the treatment (1 disease progression, 1 cons-indication for radiotherapy, 1 patient choice). Four patients had adverse event ≥ 3 (except nausea and vomiting) or grade 4 hematologic toxicity and asthenia. Treatment efficacy was: 1 RC, 10 RP, 5 SD, 1 PD. Two patients were not evaluable (1 early death, 1 patient’s refusal to further treatment). The independent peer committee judged that toxicities were acceptable and consistent with what was expected. Study is ongoing with 44 enroled patients currently.

      Conclusion
      The interim analysis of a phase II study of CRT in fit elderly patients with no resecable locally advanced NSCLC assessed by SGA showed an acceptable toxicity. Results will be upgraded for the congress.

      P3.10-041 - Impact of a Comprehensive Geriatric Assessment on management strategies in elderly patients with advanced no small cell lung cancer (NSCLC): a polled analysis of two phase 2 prospective study of the GFPC group. (ID 2418)

      • 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.
