Abstract
The United States Preventative Task Force (USPTF) previously recommended lung cancer screening using LDCT annually for individuals aged 55 to 74 years who have a 30 pack-year history and are either current smokers or quit within the past 15 years. Nevertheless, lung cancer screening using LDCT varies greatly. We describe the characteristics of individuals screened for lung cancer screening at JPS Health Network compared with the characteristics of individuals across the United States in various health settings undergoing similar screening. Our results provide insight into characteristics of individuals undergoing lung cancer screening with LDCT. Further research is needed to understand potential changes to characteristics of the screened population after implementation of the new screening guidelines.
Research Question:¿What are the demographic characteristics of patients who underwent lung cancer screening at JPS Health Network in Fort Worth, Texas? How do the demographic characteristics among individuals screened for lung cancer at JPS Health Network compare with cohorts reported in prior studies?
Background and Significance for the Questions:¿The National Lung Cancer Screening Trial (NLST) was a large, randomized trial that aimed to compare low dose computed tomography (LDCT) with conventional radiography to detect lung cancer. Based on the results of the NLST, lung cancer screening using LDCT is recommended annually for individuals aged 55 to 74 years who have a 30 pack-year history and are either current smokers or quit within the past 15 years. Nevertheless, lung cancer screening uptake based on these guidelines varies greatly among populations. Materials and Methods:¿We utilized demographic and socioeconomic data from the JPS Health Network electronic medical records to identify and describe a study cohort. Our eligible population includes patients who have sought care at JPS, between age 55 and 77 years, have no symptoms of lung cancer, have a 30-pack year smoking history, and currently smoke or quit within the past 15 years.
Results: 5 prior studies and the current study were included in our analysis. The mean age of patients screened with LDCT ranged between 61 and 66 years. The proportion of females ranged between 26% and 53%. Racial/ethnic minorities comprised between 27% and 67% of study populations. The mean age of our study population was 62.5 years (standard deviation=4.89). Our study population included an almost equal number of male and female patients, 37.8% were racial/ethnic minorities, 61.8% were current smokers, and the median duration of smoking was 40 pack-years.
Discussion/Conclusions: Our findings illuminate characteristics of individuals being screened for lung cancer in a socioeconomically marginalized population across various demographic factors. In addition, our results provide insight into how potential disparities in lung screening compare to that of the national population at large.
