Validation of Deep Learning Algorithm by using extended follow-up data in the National Lung Screening Trial
A Deep Learning Algorithm (DeepLR, Dr. Huang, etc 2019) has been developed using NLST original data from participants who had received at least two CT screening scans up to 2 years apart in the NLST. In this project, we will apply this DeepLR to extended follow-up data in the NLST. We aim to compare accuracy of DeepLR scores to predict lung cancer incidence at 1 year, 2 years, and 3 years with the Lung CT Screening Reporting & Data System (Lung-RADS) and volume doubling time, using time-dependent area under the receiver operating characteristic curve (AUC) analysis. We will also modify DeepLR with more clinical variables.
The aims of this study are i) to compare accuracy of DeepLR scores to predict lung cancer incidence in extended NLST follow-up data, and 2) to modify DeepLR by adding more clinical variables.
