Purpose

The goal of this observational cohort study is to learn how toxin and occupational exposures, germline genetic variation, and immune dysregulation relate to B-cell non-Hodgkin lymphoma among active-duty service members and other Military Health System beneficiaries. The main questions are whether specific exposures and germline variants are associated with B-cell NHL subtype, immune dysfunction, and clinical outcomes. Participants will complete exposure and medical-history surveys, provide biospecimens for immune and genomic testing, and may be followed annually for up to 3 years.

Inclusion Criteria

  • Age 4 years old and older with a clinical diagnosis of B-cell NHL. - Must be willing to undergo phlebotomy and/or skin punch biopsy. - Must be willing to undergo whole genome sequencing, which includes return of primary and secondary findings.

Exclusion Criteria

  • Has any condition that, in the opinion of the Principal Investigator, contraindicates participation in this study. Examples of situation that may contraindicate participation include but are not limited to a) some cases of cerebral vascular accidents where an individual no longer has the capacity to make their own medical decisions and a conservator or responsible family member is not available and b) an individual has active suicidal ideation and is a danger to themselves at the time of enrollment. - Does not have access to health care and primary care clinician. - Actively undergoing induction treatment for NHL.

Detailed Description

This prospective observational registry and biorepository study evaluates the relationship between occupational/environmental toxin exposures, immune dysregulation, and germline genetic susceptibility in active-duty service members (ADSMs) and other Military Health System (MHS) beneficiaries with B-cell non-Hodgkin lymphoma (NHL). Participants will be enrolled into one of three cohorts based on disease status and age, including individuals in remission, newly diagnosed adults, and treatment-naïve pediatric patients. The study will collect clinical, epidemiologic, immunologic, and genomic data longitudinally for up to 3 years. Participants will complete standardized surveys assessing demographics, military history, occupational/environmental exposures, medical history, and family history. Additional military exposure data may be obtained from the Department of Defense Individual Longitudinal Exposure Record (ILER). Clinical data abstracted from the electronic medical record will include lymphoma subtype, staging, pathology, treatment history, laboratory values, infectious complications, immune phenotyping, treatment response, recurrence, second malignancies, and survival outcomes. Biospecimens may include peripheral blood, skin fibroblasts, residual tumor tissue, bone marrow aspirate, and archived serum samples from the Department of Defense Serum Repository (DODSR). Germline and somatic genomic analyses will be performed using next-generation sequencing platforms, including whole genome sequencing. Immunologic analyses may include lymphocyte subsets, B-cell phenotyping, T-cell phenotyping, activation markers, cytokine profiling, and functional immune assays. The primary objectives are to characterize toxin exposures and immune dysregulation in B-cell NHL, identify germline pathogenic variants associated with lymphoma susceptibility, and establish a comprehensive longitudinal database and biospecimen repository for future translational research. Exploratory analyses will evaluate relationships among environmental exposures, genomic variants, immune phenotypes, lymphoma subtype, and clinical outcomes.

Notice

Study information shown on this site is derived from ClinicalTrials.gov (a public registry operated by the National Institutes of Health). The listing of studies provided is not certain to be all studies for which you might be eligible. Furthermore, study eligibility requirements can be difficult to understand and may change over time, so it is wise to speak with your medical care provider and individual research study teams when making decisions related to participation.
