ASTRO: SBRT doubles survival in early-stage lung cancer
By Brian Casey
BOSTON - Patients with stage I non-small cell lung cancer who were treated with stereotactic body radiation therapy (SBRT) had more than twice the survival of patients treated with conventional radiation therapy, according to a study presented on Sunday at the American Society for Radiation Oncology (ASTRO) meeting.

ASTRO: Outreach boosts radiation therapy rates for blacks
By Brian Casey
BOSTON - A patient outreach program essentially eliminated the treatment gap between the number of black and white patients who received radiation therapy for early-stage lung cancer, according to a paper presented on Monday at the American Society for Radiation Oncology (ASTRO) conference.

Later positive CT lung scans portend worse outcomes
By AuntMinnie.com staff writers
Individuals undergoing annual CT lung cancer screening fare worse when the results are positive in the second or third annual round, concludes a new study based on the National Lung Screening Trial. Conversely, patients who had a noncancerous positive result at the first screening lived longer.

Advanced visualization tool assesses lung disease
By Eric Barnes
An Australian start-up firm called 4Dx has developed a new technique that combines fluoroscopy and advanced visualization to generate high-resolution images of lung-tissue motion and airflow. The firm hopes the technology will enable researchers to view and measure abnormal function in lung regions at the earliest clinical stages of disease.

How low can CT radiation dose go for lung screening?
By Eric Barnes
We're making progress in the race to reduce radiation dose for CT lung cancer screening to ever-lower levels. But as dose drops, image noise grows. Fortunately, researchers are refining image processing techniques that can improve image quality while driving CT dose down to the level of a chest x-ray.

Lung abnormalities at CT linked to in-hospital death
By Eric Barnes
In critically ill patients, the presence of interstitial lung abnormalities detected on CT scans increases a patient's risk of dying in the hospital, concludes a recent study. But the modality can help by diagnosing more patients and identifying those at greater risk.

DR tomo beats x-ray, especially for small chest lesions
By Brian Casey
Radiologists who interpreted images acquired with a digital radiography (DR) tomosynthesis system were nearly four times more likely to find chest nodules than those interpreting conventional DR studies -- and tomo's edge grew as the nodules got smaller, according to a new study in Radiology.

COPD severity mirrors lung cancer incidence
By Eric Barnes
A new analysis of patients who participated in the National Lung Screening Trial shows a clear relationship between the severity of chronic obstructive pulmonary disease (COPD) and lung cancer incidence at screening. The findings suggest that COPD patients should be included in CT lung screening programs.
