title = "Combining three cohorts of world trade center rescue/recovery workers for assessing cancer incidence and mortality",
abstract = "Three cohorts including the Fire Department of the City of New York (FDNY), the World Trade Center Health Registry (WTCHR), and the General Responder Cohort (GRC), each funded by the World Trade Center Health Program have reported associations between WTC-exposures and cancer. Results have generally been consistent with effect estimates for excess incidence for all cancers ranging from 6 to 14% above background rates. Pooling would increase sample size and de-duplicate cases between the cohorts. However, pooling required time consuming steps: obtaining Institutional Review Board (IRB) approvals and legal agreements from entities involved; establish-ing an honest broker for managing the data; de-duplicating the pooled cohort files; applying to State Cancer Registries (SCRs) for matched cancer cases; and finalizing analysis data files. Obtaining SCR data use agreements ranged from 6.5 to 114.5 weeks with six states requiring >20 weeks. Records from FDNY (n = 16,221), WTCHR (n = 29,372), and GRC (n = 33,427) were combined de-duplicated resulting in 69,102 unique individuals. Overall, 7894 cancer tumors were matched to the pooled cohort, increasing the number cancers by as much as 58% compared to previous analyses. Pooling resulted in a coherent resource for future research for studies on rare cancers and mortality, with more representative of occupations and WTC-exposure.",

note = "Funding Information: The current project, “Incidence, Latency, and Survival after World Trade Center Exposure,” was funded by the National Institute for Occupational Safety and Health (NIOSH) in 2016 to establish the “Combined WTC Rescue/recovery Cohort” (the combined Cohort), a study population that includes rescue/recovery workers from the three cohorts described above. The overall aim of the project was to pool and de-duplicate data from three cohorts (FDNY, WTCHR, and GRC) for joint research on cancer incidence, latency and survival. The study design called for use of identical case ascertainment methods across the cohorts using state cancer registries; it also called for collaboration with the New York State Cancer Registry to manage and coordinate data pooling, and linking pooled data to 13 SCRs, ensure data security and confidentiality, and to harmonize data formats. There was also agreement to use a common exposure metric in the analysis.
