Eligibility Criteria:
Inclusion Criteria:~* Previously untreated histologically or cytologically documented B-cell non-Hodgkin's lymphoma; the following histologies are eligible: diffuse large B-cell lymphoma, high-grade large cell immunoblastic lymphoma, anaplastic large cell lymphoma, Burkitt's lymphoma, high-grade B-cell lymphoma, Burkitt-like (small non-cleaved lymphoma)~* Tumors must be CD20 positive~* Documented HIV infection: documentation may be serologic (ELISA, western blot), culture, or quantitative PCR or bDNA assays~* Evaluable or measurable disease~* Stage I and IE or Stage II-IV disease patients~* ANC \>= 1000 cells/mm\^3~* Platelet count \>= 75,000/mm\^3 unless cytopenias are secondary to lymphoma~* All patients must be off colony stimulating factor therapy at least 24 hours prior to chemotherapy~* Transaminase =\< 5 times the upper limit of normal unless secondary to hepatic infiltration with lymphoma or isolated hyperbilirubinemia associated with the use of indinavir or other antiretrovirals~* Total Bilirubin \< 2.0 unless secondary to hepatic infiltration with lymphoma or isolated hyperbilirubinemia associated with the use of indinavir or other antiretrovirals; for bilirubin \> 3.0 due to hepatic involvement the initial dose of doxorubicin will be decreased by 50% and the initial dose of vincristine will be omitted~* Creatinine \< 2.0 unless due to lymphoma~* KPS \>= 50 (ECOG PS 0, 1, or 2)~* Able to give consent~* Female patients must have a negative pregnancy test within 72 hours of entering into the study; males and females must agree to use adequate birth control if conception is possible during the study; women must avoid pregnancy and men avoid fathering children while in the study~* Patients already receiving erythropoeitin or G-CSF are eligible~* Patients must have a left ventricular ejection fraction that is at or above the lower institutional limits of normal, as assessed by nuclear scan or echocardiogram obtained within 12 weeks of registration~* Lymphomatous meningitis (patients with a positive CSF cytology are eligible)~Exclusion Criteria:~* Previous chemotherapy or radiotherapy for this lymphoma~* Primary Central Nervous System Lymphoma (parenchymal brain or spinal cord tumor)~* Acute active HIV-associated opportunistic infection requiring antibiotic treatment; patients with mycobacterium avium are not excluded; chronic therapy with potentially myelosuppressive agents is allowed provided that entry hematologic criteria are met~* Concurrent malignancy (excluding in situ cervical cancer, or non-metastatic non-melanomatous skin cancer, or Kaposi's sarcoma not requiring systemic chemotherapy)~* Previous therapy with rituximab within 12 months; patients treated with rituximab more than 12 months earlier are eligible only if it was given for indications other than the treatment of intermediate- or high-grade lymphoma (eg, low-grade lymphoma or ITP)

Study Arms:
- Arm I (Type: EXPERIMENTAL): Patients receive rituximab intravenously (IV) over 2-4 hours prior to each course of chemotherapy. Treatment repeats every 3 weeks for 4-6 courses. Patients who achieve a complete response after 4 courses of chemotherapy and rituximab receive additional rituximab alone weekly for 2 weeks.
- Arm II (Type: EXPERIMENTAL): Patients do not receive rituximab concurrently with chemotherapy. Beginning 4 weeks after completion of chemotherapy, patients receive rituximab IV over 2-4 hours weekly for 6 weeks.

Based on this trial design, predict the completion outcome and termination type (if applicable).

Answer: outcome: complete
