Lung Cancer
Low-Dose Spiral CT

Frederic Grannis, MD, head, Section of Thoracic Surgery, and Arnold Rotter, MD, CT section chief, Diagnostic Radiology, are developing the City of Hope Early Lung Cancer Detection Project. The project uses low-dose spiral computed tomography (CT)—an x-ray exam that is more sensitive than a chest x-ray—to increase the likelihood of early detection. Today, only about 20 percent of lung cancers are found at an early stage. In contrast, a recent trial of low-dose spiral CT of the lung detected more than 80 percent of cancers at an early stage. The technique should improve the survival of lung cancer patients, just as better screening processes have improved survival rates for breast cancer, colon cancer, and prostate cancer.
