Brief summary

Background: * Positron emission tomography (PET) uses radioactive substances called radiotracers to locate areas of cancer in the body. For this test, the patient is given an injection of the radiotracer and lies in a large donut-shaped scanner that detects where in the body the radioactivity accumulates. Computed tomography (CT) scans use low dose x-rays that help to better localize where the radioactive tracer is concentrating. PET/CT scans are usually done in lymphoma patients before treatment starts and at the end of treatment to evaluate the response to therapy. * PET scans typically use a sugar-like radioactive tracer called fluorodeoxyglucose (FDG) and low-dose x-rays. Sometimes, however, FDG PET scans show what looks like active disease and presence of a mass after chemotherapy even when there are no live cancer cells. Doctors have particular problems in evaluating response to treatment when this happens because they can't tell if the mass is active cancer or just dead tumor cells. * An experimental radiotracer called 18F- Fluorothymidine (FLT) has high uptake in active tumor cells and may be better able to evaluate treatment response. Objectives: \- To test the use of FLT PET/CT imaging in assessing treatment response in patients with lymphoma. Eligibility: \- Patients 18 years of age or older who are enrolled in a lymphoma therapy study at the National Institutes of Health (NIH) Clinical Center or in the Cancer and Leukemia Group B (CALGB) 50330 study at another location. Design: \- There are two arms in this study: * The first arm evaluates FLT as an early predictor of tumor response to therapy. Patients are imaged with FLT and FDG PET before starting treatment, following two cycles of therapy and after treatment ends. * The second arm evaluates the ability of FLT to distinguish if a mass that remains after treatment has viable cancer or dead tissue. Patients who have completed treatment and in whom FDG PET shows a remaining tumor mass are imaged with FLT PET. Following the scan, the tumor is biopsied for verification.

Detailed description

Background: * 3-deoxy-3-18F-fluorothymidine (FLT) positron emission tomography (FLT PET)/Compute tomography (CT) has been shown to correlate with the rate of cellular/tumor proliferation. * The Imaging Subcommittee of the International Harmonization Project in Lymphoma recommends performing fluorodeoxyglucose (FDG) positron emission tomography (PET) at least 3 weeks, and preferably 6-8 weeks after chemotherapy or chemoimmunotherapy and 8-12 weeks after radiation or chemoradiation therapy due to high FDG accumulation in inflammatory tissues. * FLT uptake in inflammatory lesions is less prominent than FDG and it is likely that FLT PET/CT can better differentiate inflammation from tumor. * FLT PET/CT imaging is expected to better differentiate between treatment induced inflammation and malignancy and should enable early prediction of therapeutic response. * FLT PET/CT imaging is expected to differentiate between residual inflammatory residual masses from residual malignancy and therefore guide appropriate treatment. Primary Objectives: * To estimate the diagnostic accuracy of FLT PET/CT as an early indicator of complete response to therapy in B and T cell lymphoma. * To estimate the diagnostic accuracy of FLT PET/CT in the evaluation of residual masses after therapy. Eligibility: * Participant must be enrolled in a lymphoma therapy study at the National Institutes of Health (NIH) Clinical Center OR be enrolled in the CALGB 50303 study at another site OR undergoing a new course of treatment of lymphoma at another facility. The National Cancer Institute (NCI) Laboratory of Pathology will confirm diagnosis for subjects enrolled at all CALGB study sites. * Participants must have a clinical course consistent with lymphoma and have available documentation of lymphoma from either the NCI or from an outside pathology laboratory. * Subjects enrolling in the early response arm must undergo baseline FLT PET prior to receiving a new course of lymphoma therapy. * Subjects enrolling in the residual mass evaluation arm can be enrolled at the time the FDG avid residual mass is discovered (i.e. no pre-therapy FLT image is required). * Subjects can enroll in both arms of the study. * Participant must be 18 years or older. * Eastern Cooperative Oncology Group (ECOG) Performance score of 0 or 1. * Serum glutamic-oxaloacetic transaminase (SGOT), serum glutamic-pyruvic transaminase (SGPT) less than 5 times upper limit of normal (ULN). * bilirubin less than or equal to 2 times ULN. Design: There are 2 arms in this study * The first arm will assess FLT as an early predictor of tumor response to therapy (treatment naive or recurrent disease). Subjects are imaged with FLT and FDG PET pre-therapy, following 2 cycles of therapy and post therapy. * The second arm will assess lymphoma patients with FDG PET positive residual mass. Subjects are imaged with FLT PET prior to standard of care biopsy of residual mass. If initial FDG PET data is not available in Digital Imaging and Communications in Medicine (DICOM) format or is of suboptimal image quality, a repeat FDG PET/CT at the study site may be required. * We will accrue 70 participants (40 in the early response arm and 30 in the residual mass arm) to this study.

Time to Progression

The time to progression (defined as time in months from 3'-deoxy-3'-\[18F\] fluorothymidine (FLT)-scan until patient progressed) was compared between the two groups (patients with higher Maximum Standard Uptake Value (SUVmax) vs lower SUVmax, using the median SUV value).

Time frame: up to 4.5 years

Population: 3/6 participants were analyzed because 3 did not progress while on study. Data collected only from the Group of patients scanned at baseline and after chemotherapy for this Outcome Measure.

Tumor(s) Maximum Standard Uptake Value (SUVmax) at Baseline and at Mid-treatment (Post-2 Cycles) Scan

The SUVmax (defined as radiotracer uptake in a region of interest normalized by the injected activity and body weight) was measured within the tumor(s). The SUVmax was defined as the uptake value of the hottest pixels, within a volume of interest containing the entire tumor(s). SUVmax was calculated at baseline and after 2-cycles of therapy.

Time frame: Up to 4.5 years

Population: 8/9 participants were analyzed because the FLT dose failed synthesis in 1 participant, 1 participant refused to be imaged.

Tumor(s) Maximum Standard Uptake Value (SUVmax) at Baseline Scan and SUVmax After Completion Scan in Responders and Non-responders' Patients

The SUVmax (defined as radiotracer uptake in a region of interest normalized by the injected activity and body weight) was measured within the tumor(s). The SUVmax was defined as the uptake value of the hottest pixels, within a volume of interest containing the entire tumor(s). SUVmax was calculated at baseline and after completion of therapy.

Time frame: up to 4.5 years

Population: 8/9 participants were analyzed at baseline and 6/9 were analyzed after completion of therapy because 6 patients completed the 3 scans (baseline, at 2-cycles and after completion of therapy). This outcome measure data is collected only for one of the Arm/Group. The other group of participants were not scanned at baseline and after treatment. This data is for baseline (8 patients) and after therapy (6 patients). The outcome measure refers to baseline and after completion of therapy.

Tumor Uptake With Fluorothymidine (FLT) - Maximum Standard Uptake Value (SUVmax)

The maximum standard uptake value (SUVmax) (defined as radiotracer uptake in a region of interest normalized by the injected activity and body weight) was measured within the tumor(s). The SUVmax was defined as the uptake value of the hottest pixels, within a volume of interest containing the entire tumor(s).

Time frame: Up to 4.5 years

Population: 6/9 participants were analyzed after completion of therapy because the FLT dose failed synthesis in 1 participant at baseline and was not scanned at completion, 1 participant refused to be imaged and 1 participant missed scan appointment. The other group of participants were not scanned at baseline and after treatment.

Number of Participants With Non-serious Adverse Events Assessed by the Common Terminology Criteria for Adverse Events (CTCAE v4.0)

Here is the number of participants with non-serious adverse events assessed by the Common Terminology Criteria for Adverse Events (CTCAE v4.0). A non-serious adverse event is any untoward medical occurrence. A serious adverse event is an adverse event or suspected adverse reaction that results in death, a life-threatening adverse drug experience, hospitalization, disruption of the ability to conduct normal life functions, congenital anomaly/birth defect or important medical events that jeopardize the patient or subject and may require medical or surgical intervention to prevent one of the previous outcomes mentioned.

Time frame: Date treatment consent signed to date off study, approximately 4 years, 7 months and 9 days.

Population: 8/9 patients were injected with the tracer (FLT) and scanned in the first Arm/Group, and 21/22 in the second Arm/Group.
