WTC Chest CT Imaging Archive

Lung Cancer Clinical Trial

Official title: Pulmonary Diseases in WTC Workers: Symptoms, Function, and Chest CT Correlates

Status Active, not recruiting

Clinical Trial Summary

Dr. Rafael E de la Hoz and colleagues have performed standardized and computer-assisted readings of all chest CT scans received by WTC workers and volunteers at the Mount Sinai Medical Center between 2003 and 2016. The clinical team sought to assess all findings suggestive of airway, interstitial, and neoplastic disease in a systematic way, and correlate those findings with clinical, functional, and exposure indicators. The study team's research will also involve analyses of longitudinal imaging and functional trends, and characterization of the WTC related lower airway diseases and their risk factors, with a focus on obesity-related imaging markers. The study team also plans to characterize the transitions into chronic obstructive pulmonary disease (COPD) among these workers.

Clinical Trial Description

The goal of this proposal is to characterize WTC-related lower airway disorders, and use novel imaging approaches to the investigation of obesity, one of their most important risk factors for poor clinical outcome and chronicity. To that end, the clinical team will utilize the WTC Pulmonary Evaluation Unit Chest CT Imaging Archive, an already established large imaging database, linked to extensive related databases that include disease symptoms, both pre-WTC and WTC-related occupational exposures, detailed pulmonary function and longitudinal spirometry measurements, visual imaging classification and grading, and quantitative computer assisted method (QCAM) measurements of airway, pulmonary parenchymal, pleural, and cardiovascular abnormalities. During the course of the proposed research project, the clinical team will continue to enrich most sources of data with periodic updates, in order to accrue information on the trajectories of the different clinical, functional, and imaging abnormalities observed in this population, and investigate the role of key adverse risk factors directly, and in collaboration with other investigators. In a related project, the research team will focus on COPD, classifying its severity, investigating its diagnostic stability, progression, and transitions, characterize structural abnormalities as assessed by chest CT imaging, and examine the interaction of WTC-related exposure levels with tobacco smoking on increasing the risk of for the disease.
