Medically Inoperable Lung Carcinoma: The Role of Radiation Therapy.

Although surgery has traditionally been the treatment of choice for patients with resectable non-small cell lung cancer, for those with significant medical problems where surgery is contraindicated, radiation therapy (RT) is a reasonable treatment modality. In contrast to the widely held belief that RT confers little benefit to these patients, a review of the literature and our own series of 245 patients shows that RT can provide significant tumor shrinkage, improved symptoms, and in a small but not negligible number of patients, cure. Several prognostic factors have emerged, including patient performance status, prior weight loss, tumor size, and radiation dose.
