Thoracic disease, Research, Epidemiology, Assessment, and Treatment

Our goal is to ultimately improve the diagnosis and treatment of lung cancer for all populations. We are a multidisciplinary team of biostatisticians, nurses, thoracic surgeons and epidemiologists that perform cutting edge research in epidemiologic and clinical studies of lung cancer. We collaborate with leading investigators with expertise in genetics, epidemiology, medicine, surgery, pulmonology, bioinformatics, and health services research to improve the prevention and clinical care of lung cancer.

Congratulations to TREAT team members Melinda Aldrich, PhD, MPH, Kim Sandler, MD, and Jennifer Richmond, PhD, MSPH! They were part of the team (also including Melissa McPheeters, PhD, MPH, and Travis Osterman, DO) that won first place in the Techquity Design Challenge sponsored by the Vanderbilt Clinical Informatics Center. The title of their presentation was "Capture of Smoking History in EHR for Assessment of Lung Cancer Screening Eligibility" and their proposed revisions will be implemented in the Vanderbilt EHR.

TREAT team member research published in JAMA Oncology has played a key role in new lung cancer screening guidelines. VUMC Reporter article "Vanderbilt research played key role in new lung screen guidelines" highlights the effect this research, whose authors include TREAT members Melinda Aldrich, PhD, MPH, Kim Sandler, MD, Eric Grogan, MD, MPH, and Jeffrey Blume, PhD, had on new USPSTF lung cancer screening guidelines.

VUMC Reporter article "Surgery risk model proves invaluable during pandemic" highlights the work of a team of investigators, including TREAT members Eric Grogan, MD, MPH, Stephen Deppen, PhD, and Maren Shipe, MD, MPH, who created complex decision analysis models that balanced the risk of COVID-19 infection against the risk of disease progression if surgical procedures were delayed during the pandemic. When the team analyzed six specific disease-surgery pairs in relation to model patients, they determined that proceeding with surgery in hospitals with low perioperative COVID-19 infection rates rather than waiting three to six months would likely result in an improved five-year survival for the patients.

Nashville Lung Cancer Screening Trial

Read "Saved by the Scan", the story of a participant in the Nashville Lung Cancer Screening Trial who credits the low-dose CT scan she received as part of the trial and subsequent physician care with saving her life. 

Vanderbilt Lung Screening Program

Read "A decade after lung cancer, aspiring minister aims for a ‘significant life’". An illness and CT-scan led to a diagnosis of lung cancer for Mr. Taylor Stokes. TREAT member Eric Grogan, MD, MPH, performed the surgery to remove the tumor from Mr. Stokes’ lung and now Mr. Stokes has annual follow-up scans through Vanderbilt’s Lung Screening Program.


Vanderbilt University Medical Center’s (VUMC) Lung Screening Program for patients at high risk for cancer recently reached a milestone, enrolling more than 700 patients and performing more than 1,000 CT screening examinations. TREAT member Kim Sandler, MD, is co-director of the Lung Screening Program. Read more at
