Follicular lymphoma is a type of cancer of the lymph nodes. Lab studies are important for cancer research. They help scientists better understand differences in the cancer biology of different patients. Researchers want to collect serial samples over time from people with follicular lymphoma to help them design future treatments.


To collect a variety of samples from people with follicular lymphoma to study how these diseases progress and respond to treatment.


Adults at least 18 years old who have been diagnosed with, but have not yet had any treatment for, follicular lymphoma.


Participants will be screened with medical history and physical exam. They will answer questions about daily functioning. They will have blood and urine tests. They may have scans and have tissue samples taken.

Participants will be monitored about every 4 months for up to 2 years. They will repeat screening tests. They will have a cheek swab. A small brush will be rubbed against the inside of the cheek to wipe off some cells.

Participants will have imaging scans about every 8 months for up to 2 years.

Participants may have a bone marrow aspiration and biopsy. The hipbone will be numbed with a small needle.

A needle will be put into the hipbone, and about 2 tablespoons of bone marrow will be taken out through the needle.

Participants will continue being monitored every 6 months for up to 5 years, then 1 time a year.
