Fludeoxyglucose F 18 Positron Emission Tomography in Predicting Risk of Relapse in Patients With Non-Hodgkin's Lymphoma Who Are Undergoing Combination Chemotherapy With or Without Autologous Stem Cell or Bone Marrow Transplant
RATIONALE: Drugs used in chemotherapy work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more cancer cells. Giving chemotherapy with an autologous stem cell or bone marrow transplant may allow more chemotherapy to be given so that more cancer cells are killed. Procedures, such as fludeoxyglucose F 18 positron emission tomography (FDG-PET) (done during chemotherapy) may help doctors predict a patient's risk of relapse and help plan the best treatment.
PURPOSE: This phase II trial is studying how well FDG-PET works in predicting risk of relapse in patients with aggressive non-Hodgkin's lymphoma who are undergoing combination chemotherapy with or without autologous stem cell or bone marrow transplant.

- 2-year event free survival [ Designated as safety issue: No ]
- Overall survival [ Designated as safety issue: No ]
- Predictive value of early negative fludeoxyglucose F 18 positron emission tomography (FDG-PET) [ Designated as safety issue: No ]
- Correlation of International Prognostic Index risk category with FDG-PET results and overall outcome [ Designated as safety issue: No ]
|Study Start Date:||February 2004|
|Primary Completion Date:||February 2009 (Final data collection date for primary outcome measure)|
- Determine event-free survival of patients with aggressive non-Hodgkin's lymphoma treated with early high-dose therapy and autologous peripheral blood stem cell (PBSC) or bone marrow transplantation (BMT) based on positive fludeoxyglucose F 18 positron emission tomography (FDG-PET) results obtained during first-line chemotherapy.
- Compare event-free survival of patients treated with this regimen with historical event-free survival of patients with positive FDG-PET results obtained during first-line chemotherapy that are not treated with early high-dose therapy.
- Compare overall survival of patients treated with a standard treatment regimen vs early high-dose therapy and autologous PBSC or BMT based on FDG-PET results obtained during first-line chemotherapy.
- Determine the predictive value of an early negative FDG-PET result in these patients.
- Correlate International Prognostic Index risk category with FDG-PET results and overall outcome in these patients.
OUTLINE: This is a pilot study.
- First-line chemotherapy: Patients receive cyclophosphamide IV, doxorubicin IV, and vincristine IV on day 1, oral prednisone on days 1-5, and rituximab IV on day 1 (patients with CD20-positive disease only) OR another standard first-line chemotherapy regimen. Treatment repeats every 14-21 days for 2 or 3 courses in the absence of disease progression or unacceptable toxicity.
- Radiographic staging: Between days 11-20 of course 2 or 3 OR days 11-13 of course 3 of first-line chemotherapy, patients receive fludeoxyglucose F 18 (FDG) IV. One hour later, patients undergo whole-body FDG-positron emission tomography (PET) and CT scan. Patients with no evidence of malignant disease by FDG-PET (i.e., negative result) receive a standard treatment regimen that may include localized radiotherapy for limited stage or bulky disease followed, 4-6 weeks later, by a repeat whole-body FDG-PET and CT scan. Patients with progressive disease after first-line chemotherapy are removed from the study. Patients with evidence of malignant disease by FDG-PET (i.e., positive result) and stable disease or better proceed to ESHAP chemotherapy.
- ESHAP chemotherapy: Patients receive etoposide IV over 2 hours, methylprednisolone IV, and cisplatin IV over 3 hours on days 1-4 followed by cytarabine IV over 2 hours on day 5. Patients with CD20-positive disease also receive rituximab IV on day 1. Treatment repeats every 14-21 days for 2 courses in the absence of disease progression or unacceptable toxicity. Beginning 1 day after completion of course 2, patients receive filgrastim (G-CSF) subcutaneously once daily followed by leukapheresis to collect peripheral blood stem cells (PBSC). Some patients may also undergo bone marrow (BM) harvest if sufficient PBSC are not collected. Patients with a sufficient number of stem cells proceed to high-dose therapy and autologous PBSC transplantation (PBSCT) or BM transplantation (BMT).
- High-dose therapy and PBSCT or BMT: No more than 4 weeks after completion of PBSC collection or BM harvest, patients receive high-dose therapy that may include cyclophosphamide and total-body irradiation OR busulfan and cyclophosphamide. Patients then undergo PBSCT or BMT. Between 4-6 weeks after completion of PBSCT or BMT, patients undergo repeat whole-body FDG-PET and CT scan. Patients may also undergo consolidative radiotherapy to the sites of bulky disease at the discretion of the physician.
After completion of study treatment, patients are followed at 4 weeks, every 3 months for 2 years, every 6 months for 1 year, and then annually for 2 years.
PROJECTED ACCRUAL: A total of 55 patients will be accrued for this study within 18 months.
