Study questions value of CT screens for lung cancer
Screening CT leads to early lung cancer diagnosis but does not cut lung cancer death rates for people who receive annual screening, according to a large international study.
Screening CT leads to early lung cancer diagnosis but does not cut lung cancer death rates for people who receive annual screening, according to a large international study.
Dr. Peter Bach and colleagues at Memorial Sloan-Kettering Cancer Center in New York City evaluated 3246 asymptomatic men and women with a median age of 60 who had smoked or still smoked for an average of 39 years. Beginning in 1998, subjects underwent screening for lung cancer with multislice CT at the Mayo Clinic in Rochester, MN, the H. Lee Moffitt Cancer Center & Research Institute in Tampa, or Instituto Tumori in Milan, Italy. Subjects received an initial CT scan and then at least three subsequent annual exams.
CT screening found nearly three times as many lung cancers as predicted. However, early detection and treatment did not lead to a decrease in advanced lung cancers or a reduction in deaths from lung cancer (JAMA 2007; 297:953-961).
Can AI Enhance CT Detection of Incidental Extrapulmonary Abnormalities and Prediction of Mortality?
September 18th 2024Emphasizing multi-structure segmentation and feature extraction from chest CT scans, an emerging AI model demonstrated an approximately 70 percent AUC for predicting significant incidental extrapulmonary findings as well as two-year and 10-year all-cause mortality.
Comparing Digital Breast Tomosynthesis to Digital Mammography: What a Long-Term Study Reveals
September 17th 2024In a study involving over 272,000 breast cancer screening exams, digital breast tomosynthesis (DBT) had a higher breast cancer detection rate and a lower rate of advanced cancer presentation at the time of diagnosis in comparison to digital mammography.
