Follicular Lymphoma Clinical Trials

Experimental: Prospective Group

Study participants with untreated, newly diagnosed follicular lymphoma will have blood collected for cfDNA testing before, during, and after their first-line treatment or observation period

Experimental: Retrospective Group

Study participants who have received first-line treatment for follicular lymphoma and are in complete remission will have blood collected for cfDNA testing. In the retrospective cohort, MSKCC patients with CRs lasting ≥10 years after induction therapy will be studied. Initial tumor tissue (if available) will be collected to examine the status of s cfDNA in patients with long-term remissions. Blood samples will be collected once, if the patient has interesting results (e.g. positive cfDNA sample despite CR on imaging, etc.) then additional blood samples may be taken during follow up visits.
