Treatment for brain cancer may include radiation therapy. Radiation therapy is the treatment of tumors with X-rays. This study is related to understanding the side effects of radiation treatment for brain tumors. This study is being conducted by the University of Rochester Cancer Center to compare the extent of side effects of brain cancer treatment with changes in levels of blood proteins called cytokines.
The purpose of this study is to evaluate the sensitivity and specificity of "A-PROTEIN" levels in patients with brain tumors. A-PROTEIN levels will be analyzed both pre and post treatment. Levels in blood and/or cerebrospinal fluid (CSF) will be analyzed and correlated with the underlying diagnosis and outcome.
The purpose of this study is to determine whether very high dosages of chemotherapy will improve the chance of surviving cancer.
This is a comparison of radiotherapy fractionation schemes for brain metastasis.
In patients with malignant glioma, to determine the efficacy of prophylaxis with LMWH (dalteparin) compared to placebo, both commenced beyond the immediate postoperative period, for the prevention of VTE.
Although malignant brain tumors are the most common type of primary brain tumor, there are a number of other benign brain tumors that exist. Many difficulties exist with treating these tumors that have led to controversies in the best treatment. A common issue among these brain tumors is the risk of long term side effects from treatment. What limits the use of curative radiation therapy is the ability to deliver a maximal dose to the tumor while minimizing the amount of radiation to the normal structures in the brain. A new method of delivering radiation, called tomotherapy, has been acquired at the Cross Cancer Institute (CCI) and will be used in this study. It has the ability to deliver a high dose of radiation to the tumor while minimizing the amount of radiation to normal brain structures. This study will use this method of radiation therapy to deliver radiation and see if the long term side effects from radiation therapy can be reduced.
This study examines surgery versus radiosurgery (highly focussed radiation) for the treatment of cancer which has spread to one spot in the brain (solitary brain "metastasis"). For these two treatment options, it will compare patients' survival times, quality of life, control rate of the brain metastases and side effects. It uses the most rigorous scientific method available called "randomisation" which minimises biases that exist with other types of studies. It will involve 30 - 40 patients.
Positron Emission Tomography (PET) is a specialised nuclear medicine procedure that uses positron emitting radiolabeled tracer molecules to measure biological activity. The most common of these radiolabeled tracers is 18F-fluorodeoxyglucose (18F-FDG), which is used to determine abnormal glucose metabolism in tumours and other sites. It has general applications in all areas where abnormal glucose metabolism may be present including in circumstances such as differentiating the tumour from scar tissue; evaluating the presence of the tumour in light of rising tumour markers and normal morphological imaging techniques; and assessing response to therapy where other techniques are deemed to be unhelpful. The Cross Cancer Institute (CCI) has recently been funded to establish a PET centre, and this study will prove the effectiveness of PET scanning in the Canadian health care environment and validate the data that have been developed in other jurisdictions in specific oncologic indications.
This study will examine whether an experimental drug called GW572016 can delay tumor growth in patients with glioblastoma multiforme (GMB, a malignant brain tumor). GW572016 is believed to affect cancer cell function by interfering with the internal signaling needed for the cancer to grow. The study will also determine whether the presence of specific proteins in the tumor can predict what effects GW572016 will have on the tumor. Patients 18 years of age and older with GMB whose brain tumor does not respond to standard medical treatment and who can undergo surgery for their tumor may be eligible for this study. Candidates are screened with a physical examination and neurocognitive examination, blood tests, electrocardiogram (EKG), echocardiogram (ultrasound test of heart function) or MUGA scan (nuclear medicine test of heart function), magnetic resonance imaging (MRI) of the head, and computed tomography (CT) of the head. CT uses x-rays and MRI uses a magnetic field and radio waves to show brain structure. Participants undergo the following tests and procedures: - MRI and blood tests before surgery. - Surgery to remove the brain tumor. - Follow-up MRIs every 8 weeks after surgery. - Follow-up echocardiograms or MUGA scans every 8 weeks after surgery. - GW572016 treatment starting 7-10 days before surgery and continuing until the patient or doctor decides it is in the patient's best interest to stop it or until the tumor worsens. (The drug is stopped temporarily for surgery and a healing period after surgery.) - Blood tests every 2 weeks to evaluate the effects of GW572016 on the body. - Blood test before the first GW572016 treatment and at the time of surgery to assess the effect of the drug on the cells and to determine how much drug is present in the blood at the time of surgery. Participants are followed in clinic at least monthly while taking GW572016. While on treatment they keep a diary documenting their daily treatments. The diary is collected at the monthly follow-up exams. After the treatment ends, patients are contacted periodically by the research staff for the rest of their lives to follow the long-term effects of the study.
