Filter by:The standard treatment approach for patients with high-grade primary brain tumors includes maximum feasible surgical resection, followed by 6 weeks of concurrent cranial irradiation and daily low-dose temozolomide chemotherapy, followed by 12 cycles of high-dose temozolomide administered for 5 consecutive days every 4 weeks [Stupp 2005]. Contrast-enhanced MRI is the current standard for evaluating the success of therapy and monitoring for tumor recurrence. MRI is typically obtained prior to initial surgery, within 24 hours after surgery, at the conclusions of cranial irradiation, and then every 8 weeks during temozolomide chemotherapy until evidence of recurrence. Despite this careful clinical and radiographic surveillance, and despite decades of research into the histologic and molecular classification of primary brain tumors, our ability to predict tumor behavior remains very limited. Some gliomas will result in overall survival times of only months, whereas other histologically-identical gliomas may yield survivals of years to decades [Carson 2007, Curran 1993, Lamborn 2004]. Current assessment of tumor response to therapy is also poor. Patients with complete radiographic response after cranial irradiation often progress rapidly post-irradiation. In contrast, some patients with enhancing masses at the end of chemoradiotherapy may respond dramatically to further chemotherapy alone, or the masses may even disappear in the absence of further therapy (so called "tumor pseudoprogression") [Chamberlain 2007]. This confounding situation demonstrates a need for better assessment of tumor response.
The goal of this clinical research study is to find the highest tolerable dose of DNX-2401 that can be injected directly into brain tumors and into the surrounding brain tissue where tumor cells can multiply. A second goal is to study how the new drug DNX-2401 affects brain tumor cells and the body in general.
The purpose of this study is to evaluate the potential of [18F]-ML-10 to serve as a non-invasive imaging tool for the early detection of apoptosis in brain metastases in response to radiation therapy. Such early detection may improve clinical management of patients with brain metastases, as it may help early identification of non-responders, and subsequently potentially lead to optimization of radiation dose, early decision on focal irradiation of selected, non-responsive lesions, or early referral of the patient to surgery. The experimental design of the present study aims to evaluate the potential of non-invasive PET examination with [18F]-ML-10, to provide the clinician early in the course of treatment, via non-invasive molecular imaging of radiation-induced apoptosis, information on tumor responsiveness, that is currently available only several weeks to months after completion of the radiotherapy.
RATIONALE: Temsirolimus may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Studying samples of blood and tumor tissue from patients with cancer in the laboratory may help doctors learn more about how this treatment is used by the body. PURPOSE: The purpose of this study is to evaluate the feasibility of using a microdialysis catheter to see what effect temsirolimus has on various biological substances associated with brain tumors over time.
The purpose of this study is to test the safety of a new plan for treating glioblastoma. The usual first treatment for glioblastoma is to give focused radiation over 6 weeks in combination with a chemotherapy called temozolomide. In this study the radiation will be given over 2 weeks in combination with temozolomide and another drug, bevacizumab, will also be given. Our idea is that this treatment plan may attack both the tumor and the blood vessels feeding the tumor more effectively. This study will look at what effects, good or bad, this approach has on the patient and the tumor.
The purpose of this study is to determine the antitumor activity of PPX in combination with temozolomide and radiation for patients with newly diagnosed brain tumors.
The purpose of this study is to determine if certain MRI imaging sequences (pictures) are more helpful to the physicians in determining if a brain tumor has recurred or if the person has radiation injury following their treatment.
The purpose of this study is to improve overall survival while maintaining a good quality of life in pediatric patients with refractory or recurrent brain tumors (medulloblastomas, supratentorial PNETs, ependymomas WHO grade II and III). Response to different chemotherapy options (intravenous versus oral chemotherapy, intraventricular chemotherapy) as part of a multimodal therapy will be assessed. Progression-free, overall survival and toxicity will be evaluated additionally.
The goal of this study is to compare patient ratings of how severe their own symptoms may be, with their caregivers' ratings of how severe they think the patients' symptoms may be. This will be compared using a questionnaire that is given to patients with brain tumors and their caregivers. Researchers will also study any effects that these patients' neurocognitive function may have on these patients' and their caregivers' ratings of how severe the brain cancer symptoms may be.
The main purpose of this study is to evaluate the safety and performance of the AutoLITT system for the treatment of recurrent/progressive glioblastoma multiforme tumors (GBM).
