FLT-PET/CT vs FDG-PET/CT for Therapy Monitoring of Diffuse Large B-cell Lymphoma

Patients will undergo conventional staging methods (CSM), including PDG-PET/CT, for their disease within 4 weeks prior to planned initiation of R-CHOP given for 6 cycles every 3 weeks. These patients will then have FLT-PET/CT and FDG-PET/CT scans performed 18-24 days after the second cycle of R-CHOP. After completion of six cycles of chemotherapy, CSM will be repeated, including FDG-PET/CT but only if the post cycle 2 FDG-PET/CT was positive to assess response and determine the appropriate patient management.

Primary Outcome Measures:
  • Positive Predictive Value (PPV) of 3'-deoxy-3'-[F-18]-fluorothymidine (FLT) Positron emission tomography (PET/CT) versus Fluorodeoxyglucose (FDG)PET/CT [ Time Frame: 24 Months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Overall survival after initiation of therapy [ Time Frame: 24 months ] [ Designated as safety issue: No ]

Estimated Enrollment: 137
Study Start Date: September 2011
Estimated Study Completion Date: December 2016
Estimated Primary Completion Date: December 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: FLT-PET/CT and FDG-PET/CT scan
Patients will have FLT-PET/CT and FDG-PET/CT scans performed 18-24 days after the second cycle of R-CHOP.
Procedure: FLT-PET/CT
Standard of Care
Other Name: FLT Positive Emission Tomography
Procedure: FDG-PET/CT
Standard of Care
Other Name: FDB Positive Emission Tomography
Drug: FLT
5 mCi IV
Other Name: fluoro-L-thymidine

Detailed Description:

-Primary Objective

Investigate whether the PPV of FLT-PET/CT is significantly higher than that of FDG-PET/CT by following up patients for at least 24 months post-therapy or until evidence of persistent disease/disease progression.

-Secondary Objectives

Investigate whether the event free survival (EFS) of patients with FDG-PET/CT-positive and FLT-PET/CT negative scans is not significantly lower than that of patients with concordantly negative FDG-PET/CT and FLT-PET/CT scans and that the NPV or FLT-PET/CT is similar to that of FDG-PET/CT

Correlate interim FLT-PET/CT and FDG-PET/CT with the International Prognostic Index (IPI), a well-established predictor of outcome in DLBCL, to determine their independent prognostic value from the IPI


Ages Eligible for Study:   Child, Adult, Senior
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • All patients must have a histologic or cytological diagnosis of de novo DLBCL and be scheduled to receive first line chemotherapy with R-CHOP given every 21 days (R-CHOP-21) within 6 weeks of their enrollment and for 6 cycles.
  • Patients must be >=18 years of age, but there will be no discrimination based on gender, race, creed, or ethnic background.
  • Patients must have an ECOG performance status of 0-2.
  • Patients must sign an informed consent, and be mentally responsible.

Exclusion Criteria:

  • Subjects with significant concurrent medical complications that in the judgment of the Principal Investigator(s) could affect the patient's ability to complete the planned trial, including the multiple imaging studies.
  • Patients with history of prior lymphoma (e.g., follicular lymphoma) and/or second cancers other than basal cell carcinoma.
  • Patients planned to be treated with R-CHOP-14 (i.e., R-CHOP given every 14 days) will be excluded (this should be extremely rare, if at all, since R-CHOP-21 is the standard treatment.
  • Patients who are scheduled to receive Rituxan or any other therapy (e.g., XRT, radioimmunotherapy) as adjuvant therapy after completion of R-CHOP-21.
  • Pregnant women will be excluded.
  • Women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) after study entry and for the duration of study participation. The effects of FLT on the developing human fetus are unknown. Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately. A screening urine human chorionic gonadtropin (hCG) (pregnancy test) will be administered in Nuclear Medicine to women of childbearing potential before each FLT scan and pregnant women will be stopped from participating further in this study.
