title: Small cell lung cancer in the elderly.
abstract: Mortality rates for patients with lung cancer remain high, despite advances both in our understanding of lung cancer biology and in survival statistics for other types of cancer. Important strategies for improving the figures for lung cancer are identification of subgroups at highest risk for the disease and targeting high-intensity therapy to patients with the greatest chance for cure. In this context, special attention must be given to the elderly population, which accounts for approximately 60% of all cancer cases. Recognizing that close to 13% of the population of the United States can be considered elderly and that this figure is expected to more than double over the next 40 years, the elderly cohort clearly has a significant impact on cancer statistics in general. While approximately 26% of lung cancer patients are potentially curable, the 74% majority has only a remote chance of being cured of their disease. More active therapeutic modalities, with a meaningful effect on survival and quality of life but with more acceptable toxicity than intensive therapy designed for patients with a good chance of cure, are clearly needed for these patients. Several studies have demonstrated that use of oral active agents such as etoposide, alone or in combination with other agents, produce an overall response rate and median survival time similar to those of the more intensive schedules. Once further studies clarify the optimum schedule for use of oral etoposide, it is hoped that its use in combination with other therapeutic agents and/or with radiation therapy will improve the overall response and survival rates among patients at high risk or with poor prognostic factors, such as the elderly.
