Eligibility

Inclusion

  • Patients with tumors other than DSRCT without measurable or evaluable disease will only be considered if they have \<20% chance of long term disease-free survival.
  • Patients with DSCRT are not required to have measurable or evaluable disease.
  • For tumors other than DSRCT, Burtomab reactivity must be confirmed by immunohistochemistry.
  • For tumors other than DSRCT, patients must have a history of tumor progression or recurrence or failure to achieve complete response with standard therapy or \<20% chance of long term disease-free survival.

Exclusion

  • Severe major organ toxicity. Renal, cardiac, hepatic, pulmonary, gastrointestinal and neurologic toxicity should all be grade 1 or less (per NCI CTC version 3 criteria) with the following exceptions: serum AST,ALT and alkaline phosphatase should be ≤5 x upper limit of normal (ULN), serum bilirubin ≤ 3 x ULN and nausea and vomiting should be ≤ grade 2 Patients with myelosuppression are not excluded if ANC ≥ 500/uL.
  • Active serious infections not controlled by antibiotics.
  • Patients with clinically suspected dense intraperitoneal adhesions preventing adequate IP distribution.
  • Platelet count should be \> 50,000/ul and hemoglobin should be \> 8gm/dl. Patients may receive platelet or red blood cell transfusions to maintain hemoglobin and platelets at clinical appropriate levels.
  • Patients previously treated with murine monoclonal antibodies will be excluded if they have a HAMA level of \>1000U/ml.
