Title
Mortality Reduction by year
Summary
We would like to request access to all the images for the PLCO study for use in our approved PLCO-24 project. In this project, we are interested in determining the rate of lung cancer deaths prevented by screening on an annual basis. The PLCO data is ideal for this due to its large size and long period of follow up. In this way we will see when the effect of screening becomes maximal as well as when the effect is no longer apparent. In order to make these determinations we will need to know when the screening occurred, and when the cancer was diagnosed, and also whether the cancer was diagnosed as a result of screening or was either interval or was diagnosed after screening was completed. We will also need to know whether the patient was alive or died of the cancer and any other information if available regarding competing cause of death or recurrent disease. We will also need to be able to compare this information with the control arm of the study.
Aims
1- Determine proportional reduction in mortality as a function of time
2- Determine when effects related to the screening reach their maximum
3- Determine when effects from screening are no longer apparent
4- Determine rates of competing caused of death
