More than 40% of cases of all lung cancers are diagnosed in patients over the age of 70 years. Elderly patients have more comorbidities and tend to be less tolerant to toxic medical treatments than their younger counterparts. Thus, clinical data obtained in a younger population cannot be automatically extrapolated to the great majority of nonselected elderly patients with non-small cell lung cancer (NSCLC). The bulk of prospective clinical data regarding chemotherapy and molecularly targeted therapy for elderly NSCLC patients come from studies in advanced disease. In elderly advanced NSCLC patients, single-agent chemotherapy with third-generation agents (vinorelbine, gemcitabine, taxanes) is to be considered the routine standard of care for unselected patients, based on phase II and III trials specifically designed for this special population. Cisplatin-based chemotherapy with cisplatin at attenuated doses has been demonstrated to be an active and feasible option in phase II trials. Among targeted therapies, the epidermal growth factor receptor tyrosine kinase inhibitors, erlotinib and gefitinib, have relevant phase II prospective data showing activity and good tolerability as first-line treatment in this population. Concerning the antivascular endothelial growth factor monoclonal antibody, bevacizumab, combined with chemotherapy, particular care must be taken for elderly patients because of the higher incidence of cardiovascular comorbidities. The lack of data on octogenarians suggest that clinicians should exercise caution when applying the existing data on chemotherapy and targeted therapies for patients aged 70-79 years to those aged >80 years. Further specifically designed clinical trials are needed to optimize medical treatment of NSCLC in elderly patients.
