Impact of the National Lung Screening Trial (NLST) publication and Medicare Lung cancer screening payment on lung cancer incidence rates: An interrupted time series analysis.

Introduction: Explore the impact of the Lung Cancer Screening Trial (NLST-September-2011) and the Medicare approval for CT-screening (CT-LCS-AP-February-2015) on lung cancer incidence rates, mortality, and the percentage of early-stage lung cancer diagnosis (ESLCD-T1-T2N0M0).

Methods: Retrospective interrupted time series analysis using SEER-18 database. All individuals with lung cancer (LC) diagnosis from 2006 to 2016 were included.

Factors associated with diagnosis of stages I and II lung cancer: a multivariate analysis.

Objective: To present the overall survival rate for lung cancer and identify the factors associated with early diagnosis of stage I and II lung cancer.

Methods: This is a retrospective cohort study including individuals diagnosed with lung cancer, from January 2009 to December 2017, according to the cancer registry at UMass Memorial Medical Center. Five-year overall survival and its associated factors were identified by Kaplan-Meier curves and Cox's proportional hazards model.
