Palliative therapy for lung cancer.

Attention to palliation is imperative in the management of patients with lung cancer, given the burden of symptoms and the incurable nature of the illness in a large proportion of patients. Focus on symptom control and enhancing quality of life can and should coexist with active treatment of the cancer process and attempts at prolongation of life. This article reviews some of the methodological issues in assessing palliation, and presents the evidence for the role of various therapeutic modalities in palliation of thoracic symptoms, including external beam radiotherapy, brachytherapy, chemotherapy, photodynamic therapy, and vascular stents. Palliation of metastatic disease, particularly bone and brain metastases, is also reviewed.
