Chemotherapy in elderly patients with advanced lung cancer. Part II: Treatment of non-small cell lung cancer (NSCLC).

Increasing interest in the treatment of elderly patients or patients with poor performance status (PS) with non-small cell lung cancer (NSCLC) has led to a number of subgroup analyses of clinical trials, and even more importantly, the conduction of trials specifically designed for this cohort. These studies allow some important conclusions. Data from retrospective studies and meta-analyses indicate that the use of platinum-based two-drug combinations in selected, fit elderly patients may produce response rates, survival, and toxicity comparable to those in younger patients. This excludes a per se inferior effectiveness of chemotherapy in the population of elderly patients with NSCLC. A number of more recently introduced agents with a favourable toxicity profile have significantly increased treatment options. Single- agent therapy with vinorelbine, when compared to best supportive care, has been shown to give a statistically significant survival benefit and improve quality of life. Conflicting data from phase II/III trials in elderly patients with NSCLC exist regarding a potential benefit of combination chemotherapy over single-agent treatment in the total cohort of elderly patients, including those with comorbidities or declining functional reserve. A review of the most important trials, assessing treatment options in elderly patients with lung cancer, either prospectively or retrospectively, is provided, and still unresolved issues are addressed.
