RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Monoclonal antibodies, such as rituximab, can locate cancer cells and either kill them or deliver cancer-killing substances to them without harming normal cells. Radiation therapy uses high-energy x-rays to damage cancer cells. Combining chemotherapy with monoclonal antibody therapy and radiation therapy may kill more cancer cells.

PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy plus rituximab and radiation therapy in treating patients who have stage I or stage II non-Hodgkin's lymphoma.

Study Design

Intervention model single group assignment
Primary purpose treatment
Masking open label
3 21-day cycles of CHOP (cyclophosphamide 750 mg/m^2, doxorubicin 50 mg/m^2, vincristine 1.4 mg/m^2, prednisone 100 mg x 5 days) + Rituximab 375 mg/m^2 (x 2 days for cycle 1, x 3 days for cycles 2-3). RT 4000-5500 cGy given in 25 fractions starting 3 weeks after completion of CHOP + Rituximab.
375 mg/m^2 on days 1,8 of cycle 1, then on days 1-3 of cycles 2-3.
750 mg/m^2 on day 10 of cycle 1, then on day 21 of cycles 2-3.
doxorubicin hydrochloride
50 mg/m^2 on day 10 of cycle 1, then on day 21 of cycles 2-3.
100 mg on days 10-14 of cycle 1, then on days 3-7 of cycles 2-3.
vincristine sulfate
1.4 mg/m^2 on day 10 of cycle 1, then on day 3 of cycles 2-3.
radiation therapy
4000-5500 cGy given in 25 fractions starting 3 weeks after completion of CHOP + Rituximab.

Primary Outcomes

Progression-free survival
time frame: every 6 weeks while on protocol treatment, then every 6 months for 2 years, then annually thereafter

Eligibility Criteria

All participants at least 18 years old.

DISEASE CHARACTERISTICS: Histologically confirmed stage I, IE, or non-bulky II or IIE non-Hodgkin's lymphoma of one of the following subtypes: Diffuse large B-cell Mantle cell High grade B-cell, Burkitt's or Burkitt like Anaplastic large cell (B-cell phenotype only) Lymphoma must express CD20 All disease must be encompassable in a single radiation port (including any resected disease) Must have at least 1 of the following adverse prognostic features: Non-bulky stage II or non-bulky stage IIE disease Over 60 years of age Zubrod performance status of 2 Elevated serum LDH A new classification scheme for adult non-Hodgkin's lymphoma has been adopted by PDQ. The terminology of "indolent" or "aggressive" lymphoma will replace the former terminology of "low", "intermediate", or "high" grade lymphoma. However, this protocol uses the former terminology.

Additional Information

Official title Evaluation of CHOP Plus Rituximab Plus Involved Field Radiotherapy for Stages I, IE, and Non-Bulky Stages II and IIE, CD20 Positive, High-Risk Localized Aggressive Histologies of Non-Hodgkin's Lymphoma
Description OBJECTIVES: I. Assess two year progression free survival after treatment with cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) plus rituximab followed by radiotherapy in patients with stage I, IE, or non-bulky stage II or IIE high risk localized intermediate or high grade non-Hodgkin's lymphoma. II. Determine the toxicity of this treatment in these patients. OUTLINE: Patients receive rituximab IV on days 1 and 8 of the first course, then on day 1 of courses 2 and 3. Patients receive cyclophosphamide IV over 1-2 hours, doxorubicin IV, and vincristine IV on day 10 of the first course, then on day 3 of courses 2 and 3. Patients receive oral prednisone on days 10-14 of the first course, then on days 3-7 of courses 2 and 3. Treatment repeats every 21 days for 3 courses in the absence of disease progression or unacceptable toxicity. Chemotherapy is followed by radiotherapy administered 5 days a week for 4-5 weeks. Patients are followed every 6 months for two years, and then annually thereafter. PROJECTED ACCRUAL: A total of 60 patients will be accrued for this study.
