The Center for Neuro-Oncology

The Center for Neuro-Oncology at The Western Pennsylvania Hospital provides specialized, comprehensive care for adults with suspected, newly diagnosed, or recurrent central nervous system tumors including malignant glial tumors, metastatic brain lesions, tumors of the vertebral column and spinal cord, and benign lesions such as meningiomas, pituitary adenomas, and low-grade astrocytomas.

Because of their interests in the treatment of these tumors and in establishing high standards of care for patients with malignant brain lesions, physicians and researchers of the Center for Neuro-Oncology serve as principal investigators in a variety of clinical trials. The Center is thus able to offer investigational as well as the most current clinical procedures for characterization of gliomas and other tumors and for treatment of these lesions.

Internet-Based Brain Tumor Study

The Center for Neuro-Oncology at The Western Pennsylvania Hospital offer patients participation in the Internet-Based Virtual Brain Tumor clinical Study, a retrospective and prospective study to determine brain tumor treatment trends and which treatments or combination of treatments have been most effective for various types of brain tumors. Participants in the study follow whatever treatment of combination of treatments their physicians recommend and use the Internet to report their treatments and outcomes. Participants are asked to mail copies of reports of all operative procedures pathology examinations, imaging studies, and treatments.

All information collected for the internet-Based Virtual Brain Tumor Clinical Study is kept in strict confidence; only statistical analyses of the data will be released. Although the study is not designed to prove the efficacy of one treatment over another, it is expected to provide information about what treatments have been most effective for each type of brain tumor. Such knowledge may increase and individuals patients' confidence in making treatment choices.

Any patient with a brain tumor is eligible to participate in this free Internet-based study, regardless of tumor type, physical or mental condition, or prior or current treatments. The Internet-Based Virtual Bran Tumor Clinical Study is located at: http://www.virtualtrials.com

Radiation Therapy

Interstitial Radiation
The Center for Neuro-Oncology conduced a trial of interstitial radiation therapy in patients with glioblastoma, placing iodine-125 implants to deliver 40 cGy/hour therapy for approximately one week to newly diagnosed tumors or tumors that had failed to respond to previous therapy.

This study was part of a National Institutes of Health randomized trial planned and written by Center for Neuro-Oncology faculty. Results indicated that patients receiving high-dose-rate therapy for a short time survived significantly longer than those not receiving any implants.

The Center for Neuro-Oncology continues to provide interstitial radiation therapy in addition to the standard therapy of intravenous chemotherapy and external beam radiation. A subsequent study being conducted at the Center is investigating the effectiveness of interstitial hyperthermia, with or without a chemotherapeutic agent, in conjunction with interstitial radiation.

External Beam Radiation
The Center for Neuro-Oncology is also conducting clinical trials of external beam radiation delivery to malignant brain tumors. Patients with a single metastatic brain tumor may undergo complete surgical resection of the tumor with or without whole brain external beam radiation therapy or a "boost" treatment of focused (conformal) radiation.

Conformal Radiation
For those with recurrent brain tumors and some patients with metastatic tumors, the center for Neuro-Oncology offers participation in a trial of three-dimensional conformal radiation therapy using the Peacock system. By applying radiation in three dimensions, the beams conform to the shape of the tumor, maximizing the dose of radiation to the tumor and minimizing damage to surrounding brain tissue.

Patients receiving conformal radiation have a customized mask placed over the face and skull for attachment of the linear accelerator localizing system. They then undergo weekday treatments for one to several weeks. The effects of therapy are evaluated from magnetic resonance and/or computed tomography scans obtained before treatment and during follow-up. Some patients may need to undergo surgery after radiation therapy, for removal of necrotic tissue.

Chemotherapy Innovations

The Center for Neuro-Oncology conducts research into new chemotherapeutic agents, optimal dosing, and novel techniques for delivery of these drugs directly into the tumor. Patients may be offered participation in the following chemotherapy protocols:

  • BCNU delivery via biodegradable implant
  • High-dose tamoxifen
  • Temosolomide
  • Multiple-agent chemotherapy
  • Antiangiogenesis drug treatment

Biodegradable BCNU Implant
The Center for Neuro-Oncology recently completed a multicenter placebo-controlled trial of the safety and efficacy of intraoperatively placed biodegradable BCNU for treatment of recurrent glioma. For the study, a total of 222 patients scheduled for re-operation to manage recurrent malignant brain tumors were randomly assigned to receive a biodegradable disc with or without 3.85 percent BCNU. The 110 patients who received active medication survived a mean of 31 weeks compared with a means of 23 weeks' survival for the 112 patients who received a placebo.

The positive results of this study have led researchers to begin investigating the use of higher doses of BCNU and the use of biodegradable wafer chemotherapy as the initial therapy for brain tumors. This research also gives promise of possible therapy for brain tumors with other chemotherapeutic agents avoids the morbidity of systemically administered agents and thus provides the patient a better quality of life during therapy.

High-Dose Tamoxifen
Patients with a glioblastoma multiforme or astrocytoma may be candidates for a trial of oral tamoxifen, which may be combined with radiation therapy and/or other chemotherapy, depending on the patient's general condition.

Temozolomide
Temozolomide, a new drug developed in England, is being investigated at the Center for Neuro-Oncology for its effectiveness in treating anaplastic astrocytomas at first relapse and in a randomized, open-label comparison trial with procarbazine for patient with biolblastoma at first relapse. Researchers are evaluating the pharmacokinetic and pharmacodynamic properties of temozolomide and the drug's efficacy, based on tumor response after 6 months of therapy.

Multiple-Agent Chemotherapy
Patients with recurrent malignant gliomas may be candidates for a study of oral procarbazine, either alone or in combination with tamoxifen. The trial is being conducted at several centers, and patients may receive radiation therapy and/or other chemotherapeutic agents, such as tamoxifen, while in the procarbazine trial.

Innovative Therapies

Novel therapies being investigated at the Center for Neuro-Oncology include interstitial hyperthermia and immune system therapies.

Combination radiotherapy, Interstitial Hyperthermia, and Chemotherapy
The Center for Neuro-Oncology is participating with five other institutions across the nation in a stud of interstitial hyperthermia in combination with interstitial radiotherapy, with or without chemotherapy, in the treatment of glioblastomas. The results of previous research at the center for Neuro-Oncology showed that administering interstitial hyperthermia with interstitial radiation therapy can enhance therapeutic effects by a factor of two. The current research protocol is designed to continue this investigation, with the possible addition of chemotherapeutic agent in some patients.

Anti-Angiogenesis Phase II Trial
A new drug that prevents neovascularization in animal studies is being investigated in a clinical trial at the Center for Neuro-Oncology and several other centers for its ability to slow the growth of glioblastomas by inhibiting tumor neovasculariation.

Patients who are candidates for this trial and who choose to participate will receive a 1-hour intravenous infusion three times a week, with follow-up evaluations by physical examination, laboratory evaluations, and MRI staging of the tumor after 4 weeks and every 8 weeks thereafter. For patients who tolerate this therapy and whose tumors respond, therapy may continue indefinitely.

Gene Transfer Therapy
As part of a national trial, the center for Neuro-Oncology will soon be able to offer gene therapy to patients with newly diagnosed malignant gliomas. For this treatment, herpes simplex thyidine kinase is injected directly into the tumor, then IV ganciclovir is given. Injection of virus into the lesion results in herpes infection limited to tumor cells; the IV ganciclovir then kills the infected cells, resulting in tumor destruction.
