A Brain Tumor is the growth of abnormal cells in the tissues of the brain. Brain tumors can be benign (not cancer) or malignant (cancer).

Giant pituitary adenoma can be safely removed through nasal route

It’s even worse than being told you have a brain tumor: having a tumor so large, it’s in a category all its own. Giant pituitary adenoma is a so-called “benign” tumor that can cause visual loss and impair many of the body’s most basic functions. But fortunately, even the largest of these giant tumors—which can grow to the size of an egg and invade nearby structures--can be treated effectively using a multimodality approach starting with minimally invasive surgery through the nose, according to a new study at the John Wayne Cancer Institute at Saint John’s Health Center.

Potential new treatment for drug resistant brain tumors

Dr. Karen Newell, Ph. D., the lead researcher for bio technology company Viral Genetics (Pink Sheets: VRAL), will address the 4th Annual Aspen Symposium on Brain Tumor Immuno- and Stem Cell Therapy. Her presentation will highlight the potential for combining chemotherapy with compounds that interfere with the ability of brain tumor cells to generate the energy needed to repair chemotherapy induced DNA damage.

STAT3 is required for proliferation and maintenance of multipotency in glioblastoma stem cells

In a study published online in advance of print in Stem Cells, Tufts researchers report that the STAT3 gene regulates cancer stem cells in brain cancer. Cancer stem cells have many characteristics of stem cells and are thought to be the cells that drive tumor formation. The researchers report that STAT3 could become a target for cancer therapy, specifically in Glioblastoma multiforme (GBM), a type of malignant and aggressive brain tumor.

Canadian health care system may be getting 'bum rap'

Amid the debate about reforming heath care in the United States, it's tough to turn on your television these days without hearing a political ad condemning the Canadian health care system.

'Gang of six' Senate negotiators heading home, will keep working during break

"Senators headed home for their August break Thursday amid an escalating partisan battle over health-care reform, with a small band of lawmakers hoping to keep their delicately negotiated compromise alive," The Washington Post reports.

Scientists illuminate brain tumors with fluorescent nanoparticles

Brain cancer is among the deadliest of cancers. It's also one of the hardest to treat. Imaging results are often imprecise because brain cancers are extremely invasive. Surgeons must saw through the skull and safely remove as much of the tumor as they can. Then doctors use radiation or chemotherapy to destroy cancerous cells in the surrounding tissue.

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.

Discovery of new molecular pathway for targeting cancer

A UCLA study has identified a way to turn off a key signaling pathway involved in physiological processes that can also stimulate the development of cancer and other diseases. The findings may lead to new treatments and targeted drugs using this approach.

Discovery of new mechanism controlling neuronal migration

The molecular machinery that helps brain cells migrate to their correct place in the developing brain has been identified by scientists at St. Jude Children's Research Hospital.

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.

New brain visualization technology enables removal of fist-sized tumor

A new technology involving the fusion of four different types of images into a 3-D map of a patient's brain has helped University of Cincinnati (UC) specialists successfully remove a fist-sized tumor from the brain of an Indiana woman.

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.

Minimally invasive treatment of brain tumors on the horizon

Duke University engineers have taken a first step toward a minimally invasive treatment of brain tumors by combining chemotherapy with heat administered from the end of a catheter.

Needle biopsies safe in 'eloquent' areas of brain

After a review of 284 cases, specialists at the Brain Tumor Center at the University of Cincinnati (UC) Neuroscience Institute have concluded that performing a stereotactic needle biopsy in an area of the brain associated with language or other important functions carries no greater risk than a similar biopsy in a less critical area of the brain.

Researchers discuss combined approach to maximize benefits and minimize risks of stem cell therapy

Once placed into a patient's body, stem cells intended to treat or cure a disease could end up wreaking havoc simply because they are no longer under the control of the clinician.

MRI analysis software helps identify early Alzheimer’s disease

Analyzing MRI studies of the brain with software developed at the Martinos Center for Biomedical Imaging at Massachusetts General Hospital (MGH) may allow diagnosis of Alzheimer's disease and of mild cognitive impairment, a lesser form of dementia that precedes the development of Alzheimer's by several years.
