This randomized phase III trial studies rituximab when given together with two different combination chemotherapy regimens to compare how well they work in treating patients with diffuse large B-cell non-Hodgkin's lymphoma. Monoclonal antibodies, such as rituximab, may block cancer growth in different ways by targeting certain cells. Drugs used in chemotherapy work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving rituximab together with combination chemotherapy may kill more cancer cells. It is not yet known which combination chemotherapy regimen is more effective when given with rituximab in treating diffuse large B-cell non-Hodgkin's lymphoma. PURPOSE: This randomized phase III trial is studying rituximab when given together with two different combination chemotherapy regimens to compare how well they work in treating patients with diffuse large B-cell lymphoma.
PRIMARY OBJECTIVES: I. To compare the event-free survival of rituximab, cyclophosphamide, doxorubicin hydrochloride, vincristine sulfate, prednisone (R-CHOP) versus dose-adjusted (DA-) etoposide, prednisone, vincristine sulfate, doxorubicin hydrochloride, cyclophosphamide, and rituximab (EPOCH-R) chemotherapy in untreated cluster of differentiation (CD)20 positive (+) diffuse large B-cell lymphomas. II. To develop a molecular predictor of outcome of R-CHOP and DA-EPOCH-R chemotherapy using molecular profiling. SECONDARY OBJECTIVES: I. To compare the response rates, overall survival and toxicity of R-CHOP versus DA-EPOCH-R. II. To define the pharmacogenomics of untreated diffuse large B-cell lymphoma (DLBCL) and correlate clinical parameters (toxicity, response, survival outcomes and laboratory results) with molecular profiling. III. To assess the use of molecular profiling for pathological diagnosis. IV. To identify new therapeutic targets using molecular profiling. V. To perform a comprehensive analysis of somatic alterations to the tumor genome and to understand which genomic alterations are somatically acquired by the tumor and which are encoded in the germ line of the patient. VI. To identify biomarkers of response to chemotherapy by fludeoxyglucose F 18 (FDG)-positron emission tomography (PET)/computed tomography (CT) imaging that are predictive of histopathologic remissions and survival in patients with stage I (mediastinal), II, III, or IV untreated DLBCL. VII. To evaluate the use of semiquantitative measurements of FDG uptake in defining FDG-PET/CT based biomarkers of response to chemotherapy in patients with DLBCL. VIII. To determine whether FDG-PET/CT measurements of tumor response after the second cycle of chemotherapy can predict clinical response. IX. To establish a standardized protocol for FDG-PET/CT image acquisition. X. To determine additional FDG-PET/CT parameters (e.g., the ratio of tumor maximum standard uptake value \[SUVmax\] to liver SUVmean; SUVs corrected for body surface area and lean body mass; nuclear medicine physician's assessment) and evaluate their utility in refining FDG-PET/CT based biomarkers of response to therapy. XI. To evaluate inter-institutional reproducibility of FDG-PET/CT measurements for this indication. OUTLINE: Patients are randomized to 1 of 2 treatment arms.

Progression-Free Survival Rate at 2 and 5 Years
Progression-free survival (PFS) is defined as the time from randomization to progression, relapse, or death from any cause, whichever occurred first. Progression (PD) or Relapse\> * ≥ 50% increase from nadir in the SPD of any previously identified abnormal node for PRs or nonresponders.\> * Appearance of any new lesion during or after completion of therapy.\> * PET+ is not a criterion for progressive disease. Patients only with PET+ findings must have evidence of progression on CT or biopsy proven.\> The PFS rate (percentage of participants who are alive and progression-free) at 2 and 5 years Kaplan Meier estimates and 95% Confidence Intervals are reported below.
Time frame: Up to 5 years post-registration
Response Rate
The overall response rate is defined as the percentage of participants with a response (Complete Response or Partial Response)
Time frame: Up to 5 years post-registration
Overall Survival Rate at 2 and 5 Years
Overall survival is defined as the time from randomization to death due to any cause. The overall survival (OS) rate (percentage of participants who are still alive) at 2 and 5 years Kaplan Meier estimates and 95% confidence intervals are reported below.
Time frame: Up to 5 years post-registration
