Practice pearls in the management of lung cancer in the elderly

Lung cancer is a disease that afflicts the elderly. It is a leading cause of cancer mortality worldwide. Treatment of lung cancer which was predominantly combination chemotherapy was initially thought to be too toxic for older patients with cancer due to their frail state. However a number of recent studies have shown that this is not necessarily true and many elderly can actually tolerate combination chemotherapy and derive just as much benefit from it as younger patients with lung cancer do. More recently it has been found that a significant proportion of lung cancer patients have tumors that harbor mutations that are targetable by molecularly targeted therapy (MTT). These targeted therapies have a much better tolerated side effect profile, hence have been used in elderly patient with lung cancer with great success. A new generation of drugs called immune checkpoint inhibitors have now come into the fray with exciting results in the second line treatment of lung cancer with a low side effect profile. A key element in deciding whether an elderly patient with lung cancer can tolerate treatment involves a detailed assessment using the comprehensive geriatric assessment (CGA). A number of CGA and clinical factors have also been found to be able to predict chemotherapy associated toxicity. This review of lung cancer in the elderly was part of a lecture on "Practice pearls in the management of lung cancer in the elderly" presented at the SIOG Annual Meeting in Prague in November 2015.
