Aging affects chemotherapy toxicity and effectiveness • Pharmacokinetic changes that increase toxicity • decreased volume of distribution (Vd) • decreased glomerular filtration rate (GFR) • decreased hepatic metabolism • decreased intestinal absorption • Pharmacodynamic changes that limit effectiveness • increased expression of multidrug resistance (MDR) gene • decreased apoptosis • increased tumour anoxia • decreased cell proliferation Balducci L, Carreca I, et al Oncologist. 2000;5:224-237.

Should Older Patients Receive Combination Chemotherapy For Advanced Stage Non-Small Cell Lung Cancer (NSCLC)? An Analysis of Southwest Oncology Trials 9509 and 9308Karen Kelly, Sheryl Giarritta, Stephen Hayes, Wallace Akerley, Paul Hesketh, Antoinette Wozniak, Kathy Albain, John Crowley, David R. Gandara
OBJECTIVES To determine the effect of age > 70 on survival, toxicity, and drug delivery in patients with a good performance status (PS) 0 - 1 receiving combination chemotherapy for advanced stage NSCLC.
METHODS SWOG 9509 Paclitaxel + Carboplatin versus Vinorelbine + Cisplatin SWOG 9308 Vinorelbine + Cisplatin versus Cisplatin A retrospective analysis was conducted on two recent SWOG trials in advanced NSCLC:
METHODS 1. The analysis identified two age groups: patients < 70 years of age and patients > 70 years of age. 2. The cohorts were compared for: a) baseline characteristics b) efficacy of treatment c) toxicity d) drug delivery
Toxicity * p-value for all grades of toxicities
CONCLUSIONS 1. Relatively few older patients (19%) entered these cooperative group trials. 2. There was a trend toward shorter survival in older patients (p=.06). 3. Grade 3-5 toxicities occurred more frequently in older patients (p=.06).
CONCLUSIONS 4. Fewer patients of any age were able to complete VC compared to PCb. 5. A significantly larger number of older patients discontinued VC due to toxicity as compared to PCb. 6. Trials should be specifically designed for this population.

Navelbine in the Elderly: Summary • E.L.V.I.S.: first Phase III trial demonstrating a survival advantage for single-agent chemotherapy vs BSC • Navelbine is generally well tolerated in the elderly patient • Age does not appear to change or increase toxicity • Greater sensitivity of some older individuals cannot be ruled out
Gemcitabine Plus Vinorelbine vs Vinorelbine Alone in Patients with NSCLC: SICOG Study • Patients with Stage IIIB/IV NSCLC • Age 70 years at diagnosis • Randomized to: • Vinorelbine 30 mg/m2 d1, 8 q 3 weeks vs. • Vinorelbine 30 mg/m2 d 1, 8 • Gemcitabine 1250 mg/m2 d 1, d 8 administered q 3 weeks

MILES Trial - Conclusions • Polychemotherapy with gemcitabine + vinorelbine does not improve outcomes compared to single-agent vinorelbine or gemcitabine • Single-agent chemotherapy should remain a standard for advanced NSCLC elderly patients • Baseline QoL predictive of outcome, though no difference observed in Qol or IADL between each arm ASCO 2001 Abstract 1230 ORAL PRESENTATION
