Brief Summary

The experimental anti-cancer drug IL13-PE38QQR, which is being developed for the treatment of malignant brain tumors, is composed of parts of two proteins: the immune system cytokine IL13 and a toxin from the bacterium Pseudomonas aeruginosa. The IL13 part of the drug binds to another protein, the IL13 receptor, when this receptor is displayed on the outside surface of cells. Cells with drug bound to the IL13 receptor take up the drug, and the toxin part of the drug then kills those cells. Since brain tumor cells display the IL13 receptor, they are potential targets that may be killed by this drug. This is a pilot study to visualize the distribution of IL13-PE38QQR infused into and around brain tumor tissue before and after surgical removal of the tumor in adult patients with recurrent malignant glioma. Stored tumor tissue will be tested for presence of the receptor protein, which is required for study entry. Eligible patients will then undergo biopsy to confirm the diagnosis of recurrent malignant glioma. IL13-PE38QQR will be infused for 96 hours into and around tumor tissue through catheters that have been placed surgically. For the first 48 hours the drug will be mixed with a radioactive tracer, so that the distribution of the drug can be followed by a type of scanning called SPECT. Surgery to remove the tumor will be performed approximately 15 days after the end of the infusion. Catheters will again be placed surgically, and IL13-PE38QQR will be infused a second time for 96 hours. Radioactive tracer will be included in the infusion for the first 48 hours. For both infusions, SPECT scans will be taken at 6, 24, and 48 hours after the start of infusion. MRI scans will be taken within 90 minutes of the 24 and 48 hour SPECT scans. Patients will be followed closely with further scans and laboratory tests until completion of the study approximately 58 days after completion of the second infusion.

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

DISEASE CHARACTERISTICS * Archival tumor sample must express IL13Rα2 by immuno-histochemistry (IHC) analysis * Must have prior histologic diagnosis of supratentorial malignant glioma (Grade 3 or 4), including glioblastoma multiforme, anaplastic astrocytoma, anaplastic oligodendroglioma, or mixed oligoastrocytoma (excludes glioma of unknown grade). Patients with clinical/radiographic diagnosis of malignant glioma may be registered pending histologic confirmation. * Must have undergone prior surgical resection and received external beam radiotherapy with at least 48 Gy tumor dose, completed at least 8 weeks prior to study * Must have recurrent or progressive supratentorial malignant glioma compared with a previous diagnostic study * Baseline tumor measured within 2 weeks prior to study entry * Stereotactic biopsy at study entry must confirm the presence of glioma (malignant, unless previously documented) * Recurrent or progressive tumor must have a solid contrast-enhancing region at least 1.0 cm and no more than 5.0 cm in maximum diameter. One satellite lesion is permitted if separated by 3 cm or less from the primary mass. PATIENT CHARACTERISTICS * Age 18 and over * Karnofsky Performance Score of at least 70 * Absolute neutrophil count at least 1500/mm\^3 * Hemoglobin at least 10 gm/dL * Platelet count at least 100,000/mm\^3 * PT and aPTT within institutional limit of normal * Must be candidate for re-operation * Must have recovered from toxicity of prior therapy. Minimum intervals required: at least 6 months after approved intratumoral chemotherapy (e.g. carmustine wafer), at least 6 weeks after nitrosourea-containing chemotherapy, at least 4 weeks after any investigational agent or any other cytotoxic chemotherapy, at least 2 weeks after vincristine or non-cytotoxic chemotherapy * Must practice an effective method of birth control during the study * Must understand the investigational nature of this study and its potential risks and benefits, and sign an approved written informed consent prior to performance of any study-specific procedure * No patients with tumor crossing the midline (tumor involving corpus callosum is permitted if not crossing midline), more than two foci of tumor, or non-parenchymal tumor dissemination (e.g. subependymal or leptomeningeal) * No patients with impending herniation (e.g. midline shift greater than 1.0 cm), uncontrolled seizures, or requirement for immediate palliative treatment * No patients who have received localized therapy for glioma, e.g. focal single-fraction radiotherapy, brachytherapy, or intracerebral infusion of chemotherapy or cytotoxin * No patients who are receiving any concurrent chemotherapy or any other investigational agent (corticosteroids are permitted) * No patients with a known allergy to iodine or to contrast medium that may be utilized in scans required by this protocol * Female patients must not be pregnant or breast-feeding * No patients unwilling or unable to follow protocol requirements
