Pre-malignant States to Hematologic Malignancies in Firefighters

Firefighters from the Charlotte Fire Department, ages 40-49 and with at least 5 years on the job experience will be offered consent for this study. Consented and eligible participants will have labs collected at the Baseline visit to evaluate for CHIP and monoclonal gammopathy. Buccal swabs (also collected at Baseline) and any remaining blood from the Baseline labs will be collected from participants who consent to collection and banking of their samples for future research. Participants will also complete the Firefighter History Assessment at Baseline.

If clonal hematopoiesis (CHIP) results are interpreted by the investigator as abnormal, the participant will be given a clinical referral if indicated for discussion of diagnosis, potential further diagnostic tests, and implications per standard CHIP management guidelines. If monoclonal gammopathy or other (concerning) abnormality of the complete blood count is detected, the participant will be provided a referral for a clinic visit for diagnostic assessments and followed up per standard of care.

If the participant proceeds with the referral and diagnostic work-up, the final diagnosis (if any) resulting from the initial diagnostic assessment(s) will be collected
