European screening trial sees lower lung cancer rates

By Eric Barnes

European radiologists, like their U.S. counterparts, have embarked on new efforts to answer the very long-term question of whether CT lung cancer screening and intervention in smokers can reduce mortality. Researchers from the Netherlands recently presented preliminary results from the Nelson trial, which is screening current and former smokers with MDCT and also includes an unscreened control group.

Lack of ischemic mitral regurgitation on postop echo doesn't preclude additional problems

By Shalmali Pal

SAN FRANCISCO - When coronary bypass surgery is performed, ischemic mitral regurgitation (IMR) must be addressed as this complication is associated with poor long-term survival. But the durability of valve repair for IMR is currently under fire, despite its popularity over replacement procedures. Unfortunately, good postoperative echocardiography results cannot guarantee that the patient will not experience IMR, according to surgeons from Canada.

CT, PET staging may negate need for mediastinoscopy in lung cancer

By Shalmali Pal

SAN FRANCISCO - Assessing lung cancer patients with CT and PET may identify some mediastinal lymph node metastases reliably enough to jettison mediastinoscopy, according to a presentation Monday at the American Association for Thoracic Surgery (AATS) meeting.

RFA demonstrates 'surprising' efficacy for treatment of lung malignancies

By Peggy Peck

NEW ORLEANS - What's good for the liver is good for the lung, according to results from a multicenter pilot trial of radiofrequency ablation (RFA). Italian investigators successfully used RFA to treat non-small cell lung cancer (NSCLC) in patients who were not candidates for surgery, external beam radiotherapy, and/or chemotherapy.

CT screening detects early lung cancers, but mortality benefits unclear

By N. Shivapriya

CT screening of high-risk patients detects many smaller early stage lung cancers, according to a study by Mayo Clinic researchers. But the data does not suggest a mortality benefit, and it is also unclear if the findings represent a true stage shift, the group concluded after a five-year prospective study of 1,520 current and former smokers, both men and women.
