Larger Debate Underlies Spiral CT Screening for Lung Cancer
Disagreement over spiral computed tomographys place in lung cancer screening continues. Nine months after results from the Early Lung Cancer Action Project were published, some proponents say that the technology could be the single most important advance in decades, with some claiming that it could ratchet up lung cancer survival to 80%. Others say that the exact benefits and risks have yet to be determined and are asking for better proof. The argument appears to reflect a much larger divide over what evidence is required and how it should be obtained before an emerging early cancer detection technology is broadly adopted.
Claudia I. Henschke, M.D., Ph.D., principal investigator of the ELCAP study and division chief of chest imaging at Cornell University Medical Center in New York, considers spiral CT a breakthrough in lung cancer screening. But as positive as her studys data look, many critics are calling for more
