This site is made available for public non-profit use, that is, by individuals, universities, research institutes and hospitals and medical practices which are non-for-profit. The site makes possible downloads of one spreadsheet calculator which produces 6-year lung cancer risk (probability) estimates according to the Tammemagi 2012 (PLCOM2012) Lung Cancer Risk Prediction Model, the details of which were published in:
Tammemagi MC, Katki HA, Hocking WG, Church TR, Caporaso N, Kvale PA, Chaturvedi AK, Silvestri GA, Riley TL, Commins J, Berg CD. Selection Criteria for Lung-Cancer Screening. New England Journal of Medicine. 2013;368(8):728-36.
Also, this site makes possible the downloading of two separate spreadsheet calculators which are based on a full (extended) model and a parsimonious model both of which predict the probability that a nodule detected on computed tomography (CT) screen is malignant. Details of these models are published in:
