What this trial studies

This observational study aims to assess whether firefighters' exposure to hazardous compounds increases the incidence of pre-malignant hematological conditions, which may lead to hematologic malignancies. Participants aged 40-49 from the Charlotte Fire Department with at least five years of service will undergo lab tests to evaluate for clonal hematopoiesis and monoclonal gammopathy. Additionally, buccal swabs and blood samples will be collected for future research. If any abnormalities are detected, participants will receive referrals for further diagnostic assessments.

Who should consider this trial

Good fit: Ideal candidates for this study are firefighters aged 40-49 with a minimum of five years of experience at the Charlotte Fire Department.

Not a fit: Patients currently diagnosed with a hematologic malignancy will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to early detection and management of pre-malignant conditions in firefighters, potentially reducing the risk of developing blood cancers.

How similar studies have performed: While there is ongoing research into the health impacts of occupational exposures in firefighters, this specific focus on pre-malignant hematological conditions is relatively novel.
