18F- Fluorothymidine to Evaluate Treatment Response in Lymphoma
Lymphoma
About this trial
This is an interventional diagnostic trial for Lymphoma focused on measuring 18F-Fluorothymidine, PET/CT, FLT, Lymphoma, FDG
Eligibility Criteria
- INCLUSION CRITERIA:
Participant must be enrolled in a lymphoma therapy study at the National Institutes of Health (NIH) Clinical Center OR be enrolled in the Cancer and Leukemia Group B (CALGB) 50303 study at another site OR undergoing a new course of treatment of lymphoma at another facility.
Participants must have a clinical course consistent with lymphoma and have available documentation of lymphoma from either the National Cancer Institute (NCI) or from an outside pathology laboratory.
Participant must be 18 years or older.
Eastern Cooperative Oncology Group (ECOG) Performance score of 0 or 1.
Ability to provide informed consent. All patients must sign a document of informed consent indicating their understanding of the investigational nature and risks of the study before any protocol related studies are performed.
For subjects enrolling in early response arm
- Must be enrolled in CALGB 50303 or a lymphoma therapy study at the NIH Clinical Center or undergoing a new course of treatment of lymphoma at another facility
- Must not have begun lymphoma therapy for this tumor occurrence/ relapse
- Prior completed therapy does NOT affect eligibility
For subjects enrolling in the residual FDG avid mass arm
- Must have a residual (18)F-fluorodeoxyglucose (FDG) positron emission tomography (PET) positive mass greater than equal to 1cm, with uptake greater than that of mediastinal blood pool.
- Participant will undergo a repeat FDG PET/CT scan if the original FDG/PET imaging performed at an outside institution is not of adequate imaging quality for subjects enrolling in the residual FDG mass arm.
EXCLUSION CRITERIA:
Known allergy to fluorothymidine.
Participants for whom enrollment would significantly delay (greater than 2 weeks) the scheduled standard of care therapy.
Participants with any coexisting medical or psychiatric condition that is likely to interfere with study procedures and/or results are excluded.
Participants with severe claustrophobia not relieved by oral anxiolytic medication or patients weighing greater than 136 kg (weight limit for scanner table).
Other medical conditions deemed by the Principal Investigator (PI) or associates to make the patient ineligible for protocol procedures.

Arm 2
Experimental
Experimental
Group A - Participants Scanned at Baseline & After Chemotherapy
Group B - Participants Scanned in the Evaluation of Residual Masses After Therapy
Patients undergo 3'-deoxy-3'-[18F] fluorothymidine (FLT) and fluorodeoxyglucose F 18 (FDG) PET/CT scans at baseline, after 2 courses of chemotherapy, and after completion of chemotherapy. Patients with residual FDG-positive mass after completion of therapy may be enrolled in group B.
Patients who have completed treatment in whom FDG-PET shows a remaining tumor mass undergo an FLT PET/CT scan . Patients also undergo a biopsy or fine-needle aspiration, if clinically indicated.
