Glioblastoma News and Research

RSS

Glioblastoma is the most aggressive and malignant form of glioma, a type of primary brain cancer. Surgery is often used to treat gliomas, along with radiation. However, since surgery and radiation fail to cure the disease, doctors may turn to additional radiation or chemotherapy. In early stages glioblastoma tumors often grow without symptoms and therefore can become quite large before symptoms arise. When the tumor becomes symptomatic, tumor growth is usually very rapid and is accompanied by altered brain function, and if left untreated the disease becomes lethal. Although primary treatment is often successful in temporarily stopping the progression of the tumor, glioblastomas almost always recur and become lethal.

Sensitizing tumor response to cancer treatment

Two forms of skin and brain cancer respond very poorly to chemotherapy and radiation: melanoma and glioblastoma multiforme brain cancer.

Gene expression patterns in cancer could aid early screening and prevention

Distinctive patterns of genes turned off - or left on - in healthy versus cancerous cells could enable early screening for many common cancers and maybe help avoid them, Medical College of Georgia scientists say.

New drug blocks common cancer pathway

Scientists have developed a new drug which can reduce the growth of tumours in mice by up to 98 per cent, according to a study published in Molecular Cancer Therapeutics ** this week.

Overcoming the big ‘nanotech’ challenges

Whether in the fields of medicine, sustainable energy supply or environmental protection, without making use of nanotechnology we will not be capable of overcoming the challenges which the future presents. In parallel with these efforts, though, it is essential that we examine the new technology very carefully for potential risks, such as those presented by free nanoparticles.

DNA alterations on human chromosome 9 linked to glioblastoma

Mayo Clinic researchers and colleagues at the University of California San Francisco (UCSF) have found a connection between DNA alterations on human chromosome 9 and aggressive brain cancer known as glioblastoma. The findings are reported in the current online issue of Nature Genetics.

New biomarker predicts brain tumor's response to cediranib therapy

A report in Cancer Research, a journal of the American Association for Cancer Research, highlights a new biomarker that may be useful in identifying patients with recurrent glioblastoma, or brain tumors, who would respond better to anti-vascular endothelial growth factor therapy, specifically cediranib.

Glioblastoma may originate in neural stem cells

University of Michigan scientists have found that a deficiency in a key tumor suppressor gene in the brain leads to the most common type of adult brain cancer. The study, conducted in mice that mimic human cancer, points the way to more effective future treatments and a way to screen for the disease early.

FDA approves Avastin (bevacizumab) for treatment of glioblastoma multiforme

The U.S. Food and Drug Administration recently approved Avastin (bevacizumab) to treat patients with glioblastoma multiforme (GBM) when this form of brain cancer continues to progress following standard therapy.

New drug restricts the growth of neuroblastoma

Researchers from the Children's Cancer Hospital at The University of Texas M. D. Anderson Cancer Center have found a new drug that restricts the growth of neuroblastoma, a childhood brain cancer.

Seattle Genetics presents new data on antibody-drug conjugate

Seattle Genetics, Inc. has announced that data from its antibody-drug conjugate (ADC) programs, SGN-35 and SGN-75, were presented at the 2009 Annual Meeting of the American Association for Cancer Research (AACR) being held in Denver, CO. Preclinical data with SGN-35 further elucidate its mechanism of action and demonstrate its superior antitumor activity in lymphoma compared with non-targeted agents. In addition, data with SGN-75 indicate its therapeutic potential in multiple types of solid tumors.

First noninvasive technique to accurately predict mutations in human brain tumors

Donald O'Rourke, MD, Associate Professor of Neurosurgery at the University of Pennsylvania School of Medicine and colleagues, were able to accurately predict the specific genetic mutation that caused brain cancer in a group of patients studied using magnetic resonance imaging (MRI).

Discovery of possible way to block the spread of deadly brain tumors

Researchers at the Translational Genomics Research Institute (TGen) may have found a way to stop the often-rapid spread of deadly brain tumors.

Discovery of chemical compound that may stop deadly brain tumors

Researchers at the University of North Carolina at Chapel Hill School of Medicine have identified a compound that could be modified to treat one of the most deadly types of cancer, and discovered how a particular gene mutation contributes to tumor growth.

Rak gene helps protect tumor suppressor in breast cancer

Scientists at The University of Texas M. D. Anderson Cancer Center have discovered a gene that protects PTEN, a major tumor-suppressor that is reduced but rarely mutated in about half of all breast cancers.

Nanobiotix reports 'proof of concept' for use of nanoparticles in treating glioblastoma multiforme

Nanobiotix has announced that an independent preclinical study has validated the applicability of using its nanoparticles-nanoPDT-to treat glioblastoma multiforme, one of the most prevalent brain tumors. Nanobiotix expects to attract corporate partners for the development of nanoPDT as the Company focuses development efforts on its nanoXray technology.

Neurokinin 1 receptor may prove useful in treating deadly brain tumors

Duke University researchers have identified a receptor on the surface of cells that may give them another avenue of attack against glioblastoma, the most common and most deadly type of brain cancer.

Discovery of marker for severity in adult brain cancer

Researchers at UT Southwestern Medical Center have identified a new biological indicator that may help identify which brain-cancer patients have the most aggressive forms of the disease.

Cannabinoids have anti-cancer effects

Guillermo Velasco and colleagues, at Complutense University, Spain, have provided evidence that suggests that cannabinoids such as the main active component of marijuana (THC) have anticancer effects on human brain cancer cells.

Angiogenesis inhibitor improves glioblastoma survival by reducing edema

The beneficial effects of anti-angiogenesis drugs in the treatment of the deadly brain tumors called glioblastomas appear to result primarily from reduction of edema - the swelling of brain tissue - and not from any direct anti-tumor effect, according to a study from Massachusetts General Hospital (MGH) researchers.
