Study: CT cost-effectively screens for lung disease in non-smoking women

Performing a high-resolution CT on non-smoking women age 24 to 53 with a collapsed lung can be a cost-effective screening for lymphangioleiomyomatosis (LAM), according to a study published online Feb. 18 in the American Journal of Respiratory and Critical Care Medicine.

LAM, a rare lung disease, occurs when cells begin to grow and spread to the lungs, kidneys, lymph nodes and vessels. "Women with LAM who first experience spontaneous lung collapse will, on average, experience two more,” according to Brent Kinder, MD, the study's senior investigator.

Kinder and colleagues of the University of Cincinnati in Ohio evaluated the cost-effectiveness of screening patients for LAM by evaluating the rates of spontaneous pneumothorax and the prevalence of LAM in relation to age, gender and smoking status. The researchers used 2007 Medicare data.

According to the authors, the prevalence of LAM in non-smoking women between the ages of 25-54 with spontaneous pneumothorax is estimated
at 5 percent, based on available literature.
