Testing the test: lung cancer staging with CT, PET, TBNA, and mediastinoscopy
By Eric Barnes
Comparing four lung cancer staging methods in a 45-minute talk might seem overambitious, but Dr. Atul Mehta was prepared. The noted pulmonologist reviewed nearly 1,500 studies on CT, PET, transbronchial needle aspiration and mediastinoscopy for a presentation at last week's Chest 2000 conference.

Radiation therapy for lung cancer patients may affect normal lung tissue
By Eric Barnes
SAN FRANCISCO - A PET imaging study presented at this week's Chest 2000 conference found that radiation therapy for lung cancer may induce changes in untreated lung tissues. Follow-up studies will be needed to determine what PET is actually finding, but the modality could play an important monitoring role in radiation therapy.

Dedicated PET and hybrid PET are equally accurate for assessing lung cancer
By Eric Barnes
SAN FRANCISCO - The images are fuzzier, but coincidence-detection style hybrid PET scanners are just as accurate as dedicated PET scanners for the diagnosis and staging of most bronchogenic carcinomas. That's the conclusion of researchers from the University Hospitals of Cleveland, who evaluated 23 patients with both systems.

FDG-PET finds all but the smallest lymph node lesions
By Eric Barnes
Detecting nodal metastases accurately is essential for evaluating patients with melanoma. A study in the September Journal of Nuclear Medicine said FDG-PET was reasonably sensitive and specific for the detection of lymph node metastases, yet it failed to adequately detect microscopic disease, and produced some false-positive results.
