Ascorbic Acid and Chemotherapy for the Treatment of Relapsed or Refractory Lymphoma, CCUS, and Chronic Myelomonocytic Leukemia

Inclusion Criteria: * Age \>= 18 years * Biopsy-proven relapsed or refractory lymphomas; relapsed is defined as a relapse that occurred after having a response to the last therapy that lasted \> 6 months; refractory is no response or relapse within 6 months; previous biopsies \< 6 months prior to treatment on this protocol will be acceptable * NOTE: Arms A/B - relapsed or refractory DLBCL within 24 months from the end of anthracycline-based therapy; no prior salvage therapy; patients can have received radiation therapy as part of initial treatment but not specifically for relapse * NOTE: Arm C patients include relapsed or refractory lymphoma patients of any type for which the recommended treatment includes one of the platinum-based regimens; of note, relapsed or refractory double-hit high grade lymphoma patients and relapsed or refractory Hodgkin lymphoma patients will be enrolled in Arm C; there is no limit on the number of prior therapies for Arm C patients; the patient must be eligible for a platinum-based regimen and must not have received the same regimen in the past without responding * Measurable or assessable disease: measurable disease is defined as measurable by computed tomography (CT) \[dedicated CT or the CT portion of a positron emission tomography (PET)/CT\] or magnetic resonance imaging (MRI): to be considered measurable, there must be at least one lesion that has a single diameter of \>= 1.5 cm * NOTE: Skin lesions can be used if the area is \>= 1.5 cm in at least one diameter and photographed with a ruler; patients with assessable disease by PET are also eligible as long as the assessable disease is biopsy proven lymphoma * Arms A/B - eligible for treatment with ifosfamide, carboplatin, and etoposide (+/- rituximab) * Arm C eligible for treatment with one of the following standard, every 3 week, platinum-based salvage regimens (with or without monoclonal antibody as appropriate for the disease): * Ifosfamide/carboplatin/etoposide (ICE) or rituximab/ifosfamide/carboplatin/etoposide (RICE); * Cisplatin, cytarabine (cytosine arabinoside), dexamethasone (DHAP) or RDHAP; * Gemcitabine hydrochloride (gemcitabine), dexamethasone, cisplatin (GDP) or rituximab, gemcitabine, dexamethasone, cisplatin (RGDP); * Gemcitabine and oxaliplatin (GemOx) or rituximab, gemcitabine and oxaliplatin (RGemOx); * Oxaliplatin, cytosine arabinoside, dexamethasone (OAD) or rituximab, oxaliplatin, cytosine arabinoside, dexamethasone (ROAD) * Eastern Cooperative Oncology Group (ECOG) performance status (PS) 0, 1 or 2 * Hemoglobin \>= 8.0 g/dL (may transfuse to meet this requirement), obtained =\< 14 days prior to registration * Absolute neutrophil count (ANC) \>= 1500/mm\^3, obtained =\< 14 days prior to registration * Platelet count \>= 75000/mm\^3, obtained =\< 14 days prior to registration * Total bilirubin =\< 2 x upper limit of normal (ULN) (if \> 2 x ULN direct bilirubin is required and should be =\< 1.5 x ULN), obtained =\< 14 days prior to registration * Alanine aminotransferase (ALT) and aspartate transaminase (AST) =\< 3 x ULN (=\< 5 x ULN for patients with liver involvement), obtained =\< 14 days prior to registration * Creatinine =\< 1.6 mg/dL; if over 1.6 then the calculated creatinine clearance must be \>= 55 ml/min using the Cockcroft-Gault formula, obtained =\< 7 days prior to registration * Negative pregnancy test done =\< 7 days prior to registration, for persons of childbearing potential only * NOTE: If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required * Human immunodeficiency virus (HIV) test done =\< 14 days prior to registration * If positive, the CD4 count must be \> 400 * Provide written informed consent * Willingness to have a central venous line \[peripherally inserted central catheter (PICC) or PORT\] * Willingness to provide mandatory blood specimens for correlative research * Willingness to provide mandatory tissue specimens for correlative research * Willingness to return to enrolling institution for follow-up (during the active monitoring phase of the study) * Willingness to follow the requirements of the intravenous ascorbic acid program schedule * ARM D: Patients who had a diagnosis of CCUS with one or more TET2 mutations or TET2 mutations with concurrent splicing genes mutations (SRSF2, U2AF1, SF3B1, and ZRSR2) or epigenetic regulator mutations (DNMT3A, EZH2, IDH1, IDH2). CCUS diagnosis being defined based on the absence of definitive morphologic evidence of hematologic neoplasms from bone marrow biopsy evaluation combined with evidence of pathogenic myeloid somatic mutation with a variant allele frequency (VAF) of at least 2% using our institution's next generation sequencing (NGS) panel (OncoHeme, Mayo Clinic) * ARM D: ECOG performance status (PS) 0, 1 or 2 * ARM D: Patients must meet at least 1 of these 3 laboratory criteria to be enrolled: * Hemoglobin =\< 10g/dL (obtained =\< 7 days prior to registration) * Absolute neutrophil count (ANC) =\< 1000/mm\^3 (obtained =\< 7 days prior to registration) * Platelet count =\< 100,000/mm\^ 3 (obtained =\< 7 days prior to registration) * ARM D: Total bilirubin =\< 2 x ULN (if \> 2 x ULN direct bilirubin is required and should be =\< 1.5 x ULN) (obtained =\<7 days prior to registration) * ARM D: Alanine aminotransferase (ALT) and aspartate transaminase (AST) =\< 3 x ULN (=\< 5 x ULN for patients with liver involvement) (obtained =\<7 days prior to registration) * ARM D: Creatinine =\< 1.6 mg/dL (obtained =\<7 days prior to registration). If \> 1.6, then the Calculated creatinine clearance must be \>= 55 ml/min using the Cockcroft-Gault formula * ARM D: Negative pregnancy test, for persons of childbearing potential only (obtained =\< 7 days prior to registration). NOTE: If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required. * ARM D: Provide written informed consent * ARM D: Willingness to
