In 2006, I-ELCAP’s findings were published in the New England Journal of Medicine. This publication was able to show that:
- lung cancers diagnosed under screening were typically small, including small cell carcinomas, and
- the estimated cure rate of patients whose lung cancer was diagnosed under screening.
After long-term follow-up of 31,456 asymptomatic participants, 484 of whom had lung cancer diagnosed under CT screening of which 414 (86%) had clinical Stage I disease, the estimated overall cure rate for the 484 patients diagnosed under CT screening was 80% (95% CI: 74% - 85%). With these and other publications, I-ELCAP has remained at the forefront of screening research and is often the first to call attention to important new topics. Such topics included, but are not limited to; nodule growth rate assessment, identification of different types of nodules (solid, part-solid, and nonsolid), differing pathologic findings and survival rates, identification of emphysema, coronary artery calcifications, mediastinal masses, and the importance of including smoking cessation into the screening program.
