Lung Cancer Models (lcmodels) R package
The R package provides individual risks of lung cancer and lung cancer death based on various published papers: Bach et al., 2003; Spitz et al., 2007; Cassidy et al., 2008 (LLP); Hoggart et al., 2012; Tammemagi et al., 2013; Marcus et al., 2015 (LLPi); Wilson and Weissfeld, 2015 (Pittsburgh); Katki et al., 2016 (LCRAT, LCDRAT, and versions constrained to a few variables); Katki et al., 2018; Cheung et al., 2019 (LYFS-CT).
This package also estimates the Life Years Gained From Screening-CT (LYFS-CT) as per Cheung et al., 2019. It requires the same variables as LCDRAT plus 12 additional comorbidities and the year of patient assessment.

The Excel tool provides individual risks of lung cancer incidence (LCRAT), lung cancer death (LCDRAT), and life gained from screening with CT (LYFS-CT) based on Katki et al., 2016, and Cheung et al., 2019.
