Fox 5 News health reporter Beth Galvin features the first “patient” in a Brain Tumor trial that combined surgery with a new experimental agent. Petey, a dog, is a part of a research trial aimed at translating new brain cancer therapies to humans by assessing results in dogs with similar diseases.
Winship Cancer Institute of Emory University neurosurgeon, Costas Hadjipanayis, MD, PhD, developed the experimental agent in his Brain Tumor Nanotechology Laboratory. Petey’s tumor was partially removed in surgery at the University of Georgia (UGA) College of Veterinary Medicine, and the new, investigational drug was infused directly into the tumor area. Now, 15 months later, his tumor has shrunk and Petey is seizure-free and doing well. Watch the full story here:
What if there were a way for 32,000 of the 160,000 lives lost each year related to cigarette smoking to be saved? There may just be. Findings from a recent study show the risk of dying from lung cancer could be reduced by 20 percent by use of a low-dose helical computed tomography (CT) scan. In other words, this type of CT screening could save over 30,000 lives a year.
Lung cancer is the leading cause of cancer-related deaths, and as such, cancer research and treatment experts are constantly looking for ways to reduce the pervasive nature of the disease. The National Cancer Institute (NCI) launched the multi-center National Lung Screening Trial (NLST) in 2002. The trial compared two ways of detecting lung cancer using low dose helical (spiral) CT vs a standard chest X-Ray. Part of this research study was actually led at Emory by radiologist and researcher Dr. Kay Vydareny.
The trial aimed to determine the effects of low-dose helical CT scans vs chest X-Rays on lung cancer death rates in high-risk populations. Both chest X-rays and helical CT scans have been used as a means to find lung cancer early, but the effects of these screening techniques on lung cancer mortality rates had not been determined.
Over a 20-month period, more than 53,000 current or former heavy smokers ages 55 to 74 joined NLST at 33 study sites across the United States. In November 2010, the initial findings from NLST were released. The conclusion? Clinical trial participants who received low-dose helical CT scans had a 20 percent lower risk of dying from lung cancer than participants who received standard chest X-rays.
While the benefits of low-dose helical CT scans in the reduction of lung cancer deaths are obvious, not every diagnostic option comes completely risk free. The CT scans can occasionally detect suspicious abnormalities that do not turn out to be lung cancer – known as false positives. Many of these abnormalities are scars from smoking, areas of inflammation or other noncancerous conditions that may require additional testing to determine that they are not harmful. These tests have been known to cause undue anxiety for patients and may sometimes lead to biopsies or surgeries.
“It is certainly an individual’s choice whether they want to be screened for lung cancer with a CT scan if they have no symptoms. However, it is important to make certain that such individuals have complete information and be well-informed before having such a scan. If a patient has symptoms, such as a persistent cough, weight loss, persistent hoarseness or trouble breathing, he or she should see a physician as soon as possible. Often these symptoms are due to something other than lung cancer, but more tests should be performed to make certain,” says Vydareny.
What should a person at high-risk for lung cancer do? The answer that all physicians agree on is to stop smoking right now, the sooner the better. Or even better … don’t start smoking ever, further reducing the chances of getting cancer or suffering from a stroke or heart attack as well.
“All physicians hope that there will be a test that can screen for early lung cancer and that the dismal prognosis of those with lung cancer will improve. Perhaps it will be screening with CT scans. Perhaps it will be a blood test,” says Vydareny. “That day hopefully will come, but it has not yet arrived. But if you are or have been a heavy smoker, your first step should be to consult your primary care physician to discuss all possible screening options.”
Winship Cancer Institute of Emory University, Georgia’s only National Cancer Institute-designated cancer center, serves as the coordinating center for cancer research and care throughout Emory University and Emory Healthcare. Seeing more than 14,000 patients each year, Winship at Emory offers patients with access to progressive resources, technology and cancer treatment options. To benefit from these investigational advancements in cancer treatment, it is important to seek care from an academic medical center like Winship at Emory, first. Through discoveries made possible by a dedicated team of many of the nation’s best physicians and researchers, Winship at Emory works hard toward a future when science triumphs over cancer.
