Demographics of Lung Cancer in
the Older Patient
Individuals > age 65: fastest growing segment of U.S. population
More than 2/3 of patients with adv. lung cancer older than 65*
Median age of diagnosis for lung cancer in the U.S. is 70*
35% of lung cancer patients > 75*
Likelihood of receiving treatment decreases with advancing age
Clinical trial participation also decreases with advancing age
– Analysis of SWOG trials 1993 – 1996 (Hutchins NEJM 341:2061,1999)
39% of patients on lung trials > 65 vs. 66% of general population > 65
– NCI analysis 1997 – 2000 (Lewis J Clin Oncol 21:1383, 2003)
42% of patients on lung trials > 65 vs. 70% of general population > 65

Chemotherapy in the Elderly Patient:
Special Challenges
Higher frequency of comorbid conditions
Higher prevalence of polypharmacy increasing the risk of
adverse drug interactions
Reduced hepatic, renal, lung function, immune
competence and bone marrow reserve
Impaired social, emotional or financial resources
Prospective Phase III Chemotherapy
Trials in Elderly Patients with
Advanced NSCLC
ELVIS (1999) (154 pts)
– vinorelbine vs. BSC: improved survival and QOL with vinorelbine
SIOG (2000) (120 pts)
– vinorelbine vs. vinorelbine + gemcitabine: improved survival, but
enhanced toxicity with the combination
MILES (2003) (698 pts)
– vinorelbine vs. gemcitabine vs. vinorelbine + gemcitabine:
overall survival similar among arms; combination regimen more
toxic
WJTOG (2006) (182 pts)
– vinorelbine vs. docetaxel: improved response, PFS and survival
with docetaxel (though underpowered to show a statistically
significant benefit wrt OS)

Trend for greater toxicity in some studies, particularly
myelosuppression
Trend for improved tolerance of carboplatin vs. cisplatin

Molecularly Targeted Agents: Role in Elderly
Patients with Advanced NSCLC
Potential for increased use given “favorable” toxicity profile
Limited prospective data to date
Retrospective analysis of BR21 showed that age did not dilute the survival
benefit of erlotinib vs placebo in the 2nd and 3rd line setting
Prospective phase II trial with erlotinib suggests benefit
Subset analyses of extended access trials with single-agent gefitinib have
demonstrated clinical activity and modest toxicity
Phase II trial of gefitinib + gemcitabine or vinorelbine (Scagliotti ASCO
2004); antineoplastic activity not enhanced; excessive toxicity for vinorelbine
and gefitinib
Prospective phase III trial of gefitinib vs vinorelbine shows equivalent
survival, improved QoL (IASLC ’07)
Retrospective analysis of bevacizumab combined with chemotherapy
suggests caution

Response rates were similar between age groups.
Elderly patients, compared with young patients, had significantly more overall and
severe (grade 3 and 4) toxicity (35% v 18%; P < .001), were more likely to discontinue
treatment as a result of treatment-related toxicity (12% v 3%; P < .0001), and had lower
relative dose-intensity (64% v 82% received > 90% planned dose; P < .001).
Conclusion: Elderly pts treated with erlotinib have similar survival and QOL benefits
compared to younger pts, with somewhat greater toxicity

Multivariate analysis revealed elderly patients with lower Brinkman index
tended to be more sensitive to gefitinib (odds ratio: 4.57, 95% confidence
interval: 0.91-22.72, p = 0.0642).
Conclusions: Tx with gefitinib appeared to be as safe and effective in
elderly patients (aged 75 or older) with NSCLC as in non-elderly patients

Gefitinib in the Elderly with NSCLC
Prospective study of gefitinib 250 mg/d in advanced chemo-exposed NSCLC pts >
70. From August 2001 to May 2003,
40 consecutive pts enrolled from three Italian institutions from 8/01 to 5/03
OR% - 5% (1 CR, 1 PR) 18 disease stabilizations (NC: 45%) lasting at least 2 mos
– six patients (15%) who had disease stabilisation of 6 months or longer,
– median duration of response was 4.4 months (range 1.7-9.2).
No data on PFS or OS
Side effects generally mild and consisted of diarrhoea and skin toxicity.
– Grade 1-2 diarrhoea in 23.6%; one pt experienced grade 4 diarrhoea, requiring
hospitalization.
– Grade 1-2 skin toxicity, including rash, pruritus, dry skin, and acne in 20 pts
(50%).
Conclusions: Gefitinib is safe and well tolerated in elderly pretreated NSCLC
patients with reasonable disease control rate.

Phase 2 trial of docetaxel and gefitinib in Txnaïve pts with advanced NSCLC > 70 yrs of age
Eligibility: chemotherapy-naïve NSCLC patients, 70 years of age or older
Tx Design:
– Docetaxel 75 mg/m(2) every 3 weeks - 2 cycles beyond maximal response
– Gefitinib 250 mg po until PD
Primary endpoint - response rate (RR); Secondary endpoints : OS and PFS
RESULTS: 44 patients initiated therapy between March 2003 and May 2005.
Seventeen patients (40%; 95% confidence interval [CI], 26%-57%) had a partial response
48% had stable disease.
Median PFS was 6.9 months (95% CI, 3.95-7.8 months).
Median survival time was 9.6 months (95% CI, 4.6-16.3 months).
Univariate analyses: sex; ECOG PS, and Charlson comorbidities index (CCI) score proved
predictors of improved survival
Multivariate analyses: female sex was a statistically significant predictor of survival.
– median survivals were 22.8 months in women and 4.8 months in men.
Most common adverse events being hyperglycemia, fatigue.
CONCLUSIONS: Combination docetaxel and gefitinib: active and well tolerated in patients
with advanced NSCLC who are 70 years of age and older; merits further investigation
especially in women

Introduction
Elderly patients (> 70 years) account for
approximately 50% of all cases of lung cancer
Elderly patients with a good performance status can
be treated with platin-based two drug combinations
Two drug combinations appear to have superior
efficacy when compared to monotherapy for the
elderly (Lilenbaum et al, J Clin Oncol 2005; Sederholm et
al J Clin Oncol 2005)
In general, when compared to younger patients, the
elderly have:
– Reduced hepatic and renal function
– Altered volume of distribution
– More co-morbid illness
Objectives
To compare the outcomes between carboplatin
and paclitaxel combination (PC) chemotherapy
and PC with Bevacizumab (PCB) for elderly
patients enrolled to ECOG 4599.
To study the differences in safety and efficacy
between elderly and younger patients treated
with PCB in ECOG 4599
Methods
Subset analysis of ECOG 4599 database
Elderly patients defined as those > 70 years of
age at the time of study entry
< 70 years comprised the non-elderly group
Data available as of November 1, 2005 (same
release date as that used for the final ECOG
technical report for the study)
Results
Eligible cases = 850 (PC : n=433; PCB : n=417)
> 70 years: n=224 (26%)
> 80 years: 1.6%
Median age:

Conclusions: Elderly
enrolled in E 4599
Proportion of elderly patients on ECOG 4599 is the highest
recorded among ECOG phase III trials.
PCB is associated with higher degree of toxicity in elderly
patients, when compared to treatment with PC alone.
No significant improvement in survival or PFS was noted with
PCB over PC for the elderly (but PC out-performed historic
controls in this study).
When compared to younger patients, the elderly experienced
more toxicity and more TRDs with PCB.
The observations are limited by the post-hoc, retrospective
nature of this analysis.
The safety and efficacy of bevacizumab-chemotherapy
combinations in elderly patients with NSCLC merits further
scrutiny.

Elderly patients with Advanced
NSCLC: Treatment Principles
Age alone should not be a criterion for treatment
selection in advanced disease
PS is the primary determinant of prognosis in
elderly patients with advanced NSCLC
Dedicated trials in patients aged 70 to 79 with PS
0-1 may no longer be necessary, but we have yet
to show the superiority of a platinum-based
regimen compared to a single agent in an elderly
specific trial
Dedicated studies are urgently needed in
octogenarians
Assessment of co-morbidities and potential
impact on outcome is an important research goal
Targeted Tx in Elderly Patients with
Advanced NSCLC: Basic Tenets
Erlotinib as a single agent is safe and feasible in both
the Tx-naïve setting and in the 2nd/3rd line venue
Bevacizumab in combination with standard
chemotherapy in Tx-naïve NSCLC yields
– improved OR% and a trend toward increased PFS, but
– demonstrates no survival advantage in post-hoc analysis
– And it causes significantly more toxicity, including
neutropenia, FN, GI bleeding, proteinuria, motor neuropathy,
dizziness, and TRDs.
E1505, while it allows elderly pts to be enrolled, does
not permit carboplatin-based therapy.
The role of other molecular-targeted agents and angioinhibitory agents merits further investigation in the
adjuvant setting, especially in the elderly, who are
likely to be under-represented in current chemo-based
adjuvant efforts
