- Brief Summary
RATIONALE: Radiolabeled monoclonal antibodies, such as iodine I 131 tositumomab, can find cancer cells and carry cancer-killing substances to them without harming normal cells. Monoclonal antibodies, such as rituximab, can block cancer growth in different ways. Some block the ability of cancer cells to grow and spread. Others find cancer cells and help kill them or carry cancer-killing substances to them. Drugs used in chemotherapy, such as cyclophosphamide, doxorubicin, vincristine, and prednisone, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving a radiolabeled monoclonal antibody together with rituximab and combination chemotherapy may kill more cancer cells.
PURPOSE: This phase II trial is studying how well giving iodine I 131 tositumomab together with rituximab and combination chemotherapy works in treating older patients with stage II, stage III, or stage IV B-cell non-Hodgkin's lymphoma.
- Detailed Description
OBJECTIVES:
* Determine the 2-year progression-free survival of older patients with previously untreated bulky stage II or stage III or IV diffuse large B-cell non-Hodgkin's lymphoma treated with iodine I 131 tositumomab in combination with rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone.
* Determine the response rate (partial response, complete unconfirmed response, and complete response) in patients treated with this regimen.
* Determine the 2-year progression-free survival and response rate (partial response, complete unconfirmed response, and complete response) in B-cell lymphoma 2 (BCL-2) positive patients treated with this regimen.
OUTLINE: This is a multicenter study.
* Rituximab and chemotherapy: Patients receive R-CHOP comprising rituximab IV over 6 hours; cyclophosphamide IV over 15-45 minutes; doxorubicin IV over 5-20 minutes; and vincristine IV over 5-15 minutes on day 1 and oral prednisone on days 1-5. Treatment repeats every 21 days for up to 6 courses in the absence of disease progression or unacceptable toxicity. Patients then undergo a restaging evaluation. Patients without progressive disease receive CHOP chemotherapy comprising cyclophosphamide, doxorubicin, vincristine, and prednisone as outlined above. Treatment with CHOP chemotherapy repeats every 21 days for 2 courses.
* Radiolabeled monoclonal antibody therapy: Approximately 4-8 weeks after completion of chemotherapy, patients receive tositumomab IV over 1 hour followed by a dosimetric dose of iodine I 131 tositumomab IV over 20 minutes. Patients then undergo gamma scans over a 1-week period in order to determine the correct treatment dose of iodine I 131 tositumomab. No more than 2 weeks after administration of the dosimetric dose, patients receive tositumomab IV over 1 hour followed by a treatment dose of iodine I 131 tositumomab IV over 20 minutes.
After completion of study treatment, patients are followed periodically for up to 5 years.
PROJECTED ACCRUAL: A total of 80 patients will be accrued for this study within 15 months.

- Primary Outcome Measures
Name Time Method Progression-free Survival (PFS) at 2 Years 0-2 years Clinical responses were evaluated according to International Workshop NHL criteria (Cheson et al, 1999). Progression disease was defined as if a (CR, CRU) was not achieved at a previous assessment, a 50% increase in the SPD of target measurable lesions over the smallest sum observed (over baseline if no decrease during therapy) using the same techniques as baseline. Appearance of a new lesion/site. Unequivocal progression of non-measurable disease in the opinion of the treating physician (an explanation must be provided). Death due to disease without prior documentation of progression. PFS is measured from date of registration to date of first observation of progressive disease, or death due to any cause. Patients last known to be alive and progression-free are censored at date of last contact.
Response Rate (Complete, Complete Unconfirmed, and Partial) 6 months Complete Response(CR) is a complete disappearance of all disease with the exception of nodes. No new lesions. previously enlarged organs must have regressed and not be palpable. Bone marrow(BM) must be negative if positive at baseline. Normalization of markers. CR Unconfirmed (CRU) does not qualify for CR above, due to a residual nodal mass or an indeterminate BM. Partial Response(PR) is a 50% decrease in the sum of products of greatest diameters (SPD) for up to 6 identified dominant lesions, including spleenic and hepatic nodules from baseline. No new lesions and no increase in the size of liver, spleen or other nodes.
- Secondary Outcome Measures
Name Time Method Number of Patients With Grade 3 Through Grade 5 Adverse Events That Are Related to Study Drug 6 months (assessed at the end of each cycle of chemotherapy for 8 cycles (1 cycle= 21 days), at restaging, and at the end of each radiolabeled antibody treatment) Adverse Events (AEs) are reported by the NCI Common Terminology Criteria for Adverse Events (CTCAE) version 3.0. For each patient, worst grade of each event type is reported. Grade 3 = Severe, Grade 4 = Life-threatening, Grade 5 = Fatal.
