Combination Chemotherapy and Denileukin Diftitox in Treating Patients With Newly Diagnosed T-Cell Non-Hodgkin Lymphoma

Study Overview
=================
Brief Summary
-----------------
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. Combinations of biological substances in denileukin diftitox may be able to carry cancer-killing substances directly to non-Hodgkin lymphoma cells. Giving combination chemotherapy together with denileukin diftitox may kill more cancer cells. PURPOSE: This clinical trial is studying how well giving combination chemotherapy together with denileukin diftitox works in treating patients with newly diagnosed T-cell non-Hodgkin lymphoma.

Detailed Description
-----------------
OBJECTIVES: Primary To evaluate failure-free survival of patients with newly diagnosed peripheral T-cell non-Hodgkin lymphoma treated with cyclophosphamide, doxorubicin hydrochloride, vincristine, prednisone (CHOP), and denileukin diftitox (Ontak®) alternating with high-dose methotrexate, leucovorin calcium, cytarabine, and Ontak® (CHOP-MONTAK regimen). Secondary To determine the response rate (CR, CRu, and PR) in these patients. To determine the overall survival of these patients. To determine the toxicity profile of this regimen. To correlate response with CD25 expression in these patients. OUTLINE: Courses 1, 3, and 5: Patients receive cyclophosphamide IV over 30 minutes, doxorubicin hydrochloride IV, and vincristine IV on day 1; oral prednisone once daily on days 1-5; and denileukin diftitox IV over 60 minutes on days 1 and 2. Treatment repeats every 21 days for 3 courses in the absence of disease progression or unacceptable toxicity. Courses 2, 4, and 6: Patients receive high-dose methotrexate (MTX) IV over 24 hours on day 1; cytarabine IV over 2 hours every 12 hours on days 2 and 3; and leucovorin calcium IV over 15 minutes every 6 hours for 8 doses beginning 12 hours after the last dose of each MTX infusion. Patients also receive denileukin diftitox IV over 60 minutes for 2 doses once MTX blood levels have cleared. Treatment repeats every 21 days for 3 courses in the absence of disease progression or unacceptable toxicity. Patients undergo tumor tissue and blood sample collection periodically for correlative studies. Samples are analyzed for CD25-positive or -negative expression and response rate via flow cytometry. After completion of study treatment, patients are followed every 3 months for 2 years, every 4 months for 1 year, every 6 months for 2 years, and then annually thereafter.
