  • Very early relapse (< 6 months from the end of initial therapy, including chemotherapy ± radiation)
  • Advanced stage (III or IV) at diagnosis who relapse less than one year from the end of initial therapy
  • Note that patients with low-stage disease (IA or IIA) at initial diagnosis, who were treated with radiation alone or fewer than four cycles of chemotherapy will NOT be eligible
• Patients must have measurable disease, documented by clinical and radiographic criteria
• Patients must have a life expectancy of >= 8 weeks (>= 56 days)

• Patients must have fully recovered from the acute toxic effects of all prior anti-cancer chemotherapy

  • At least 14 days after the last dose of myelosuppressive chemotherapy (28 days if prior nitrosourea); Note: cytoreduction with hydroxyurea can be initiated and continued for up to 24 hours prior to the start of therapy
  • At least 14 days after the last dose of a long-acting growth factor (e.g. Neulasta) or 7 days for short-acting growth factor; for agents that have known adverse events occurring beyond 7 days after administration, this period must be extended beyond the time during which adverse events are known to occur; the duration of this interval must be discussed with the study chair
  • At least 7 days after the last dose of a biologic agent; for agents that have known adverse events occurring beyond 7 days after administration, this period must be extended beyond the time during which adverse events are known to occur; the duration of this interval must be discussed with the study chair
  • At least 42 days after the completion of any type of immunotherapy, e.g. tumor vaccines
  • At least 3 half-lives of the antibody after the last dose of a monoclonal antibody
  • At least 14 days after local palliative radiation therapy (XRT) (small port); at least 150 days must have elapsed if prior total body irradiation (TBI), craniospinal XRT or if >= 50% radiation of pelvis; at least 42 days must have elapsed if other substantial bone marrow (BM) radiation
  • Patients with prior autologous or allogeneic stem cell transplant (SCT) are excluded from this study
  • At least 28 days must have elapsed since the most recent dose of bleomycin, to allow adequate time to detect evidence of bleomycin-related pulmonary toxicity
• PART A: FOR PATIENTS WITH KNOWN BONE MARROW INVOLVEMENT (Completed as of Amendment 4)
• Peripheral absolute neutrophil count (ANC) >= 1000/uL
• Platelet count >= 100,000/uL (transfusion independent, defined as not receiving platelet transfusions for at least 7 days prior to enrollment)
• PART B: FOR PATIENTS WITHOUT KNOWN BONE MARROW INVOLVEMENT
• Peripheral absolute neutrophil count (ANC) >= 750/uL
• Platelet count >= 75,000/uL (transfusion independent, defined as not receiving platelet transfusions for at least 7 days prior to enrollment)
• Patients with lymphoma metastatic to bone marrow who have granulocytopenia, anemia, and/or thrombocytopenia will be eligible for study but not evaluable for hematologic toxicity (in Part A, there will be a maximum of one per cohort); such patients must meet the blood counts as in Part A (may receive transfusions provided they are not known to be refractory to red cell or platelet transfusions); if dose-limiting hematologic toxicity is observed, all subsequent patients enrolled in Part A must be evaluable for hematologic toxicity
• Creatinine clearance or radioisotope glomerular filtration rate (GFR) >= 70 ml/min/1.73 m^2 OR

• A serum creatinine based on age/gender as follows:

  • =< 0.6 mg/dL (for 1 to < 2 years of age)
  • =< 0.8 mg/dL (for 2 to < 6 years of age)
  • =< 1.0 mg/dL (for 6 to < 10 years of age)
  • =< 1.2 mg/dL (for 10 to < 13 years of age)
  • =< 1.4 mg/dL (for females >= 13 years of age)
  • =< 1.5 mg/dL (for males 13 to < 16 years of age)
  • =< 1.7 mg/dL (for males >= 16 years of age)
• Bilirubin (sum of conjugated + unconjugated) =< 1.5 x upper limit of normal (ULN) for age
• Serum glutamate pyruvate transaminase (SGPT) (alanine aminotransferase [ALT]) < 2.5 x upper limit of normal (ULN) for age; for the purpose of this study, the ULN for SGPT is 45 U/L
• Serum albumin >= 2 g/dL
• No evidence of dyspnea at rest, no exercise intolerance due to pulmonary insufficiency, and a pulse oximetry > 92% while breathing room air
• Forced expiratory volume in one second (FEV1)/forced vital capacity (FVC) > 60% by pulmonary function test (PFT), unless due to large mediastinal mass from HL; carbon monoxide diffusion capacity (DLCO), FEV1, and forced vital capacity all > 50% predicted value; Note: pulmonary function testing is not required for children < 8 years old, or for any child who is developmentally unable to comply with pulmonary function testing
• Patients with seizure disorder may be enrolled if on anticonvulsants and well controlled
• Nervous system disorders (Common Terminology Criteria for Adverse Events [CTCAE] version [v] 4) resulting from prior therapy must be < grade 2
