appears to be more effective than MRI technology, at least in this case, because the glow allows surgeons to see microscopic remnants of the tumor and areas of the cancer that might be mistaken for edema, or swelling, Berger explained. "This is an inexpensive way to identify high grade tumors," he said. National Cancer Institute.

A report describes a case in which a patient with glioblastoma swallowed a pill, called 5 ALA, and was taken to surgery about four hours later. The medication attached itself to tumor cells, causing them to glow brightly. Once the skull was opened, Nike Air Vapormax Flyknit Gray the doctors focused a blue light on the tumor, which gave the cancerous cells a pink glow, so the surgeons could differentiate malignant tissue from healthy tissue. The research is published in the Feb. 19 issue of the Journal of Neurosurgery.

The use of 5 ALA changed the patient's prognosis. "Multi centric disease worsens the prognosis," Berger explained.

In surgery, when the surgeons viewed the fluorescent tumor cells, they could tell rather than being a new tumor, the cancer had spread from its original location on the right side of the brain through a pathway along the wall of the right ventricle. The researchers found that the use of 5 ALA during surgery enabled them to see the actual pathway of the tumor as it had spread.

While Schulder said he thinks 5 ALA probably will add about six months to the anticipated survival of patients with high grade gliomas, he said that attempts to improve the ability to remove these tumors will only go so far. "In the end, however helpful the use of 5 ALA or similar compounds may be in the surgical removal of brain cancers, it won't be the Nike Vapormax Flyknit Cookies And Cream

answer. The treatments will have to be biological to truly have an impact on survival, and ultimately, on a cure."

see precisely where a tumor has spread in the brain. Some types of tumors can be particularly difficult to identify and remove, even with the benefit of MRI and surgical microscopes.

The report focused on the case of a 56 year old man who had undergone resection of a glioblastoma located in the right occipital lobe of his brain in 2005. Several years later, when symptoms reappeared, an MRI scan showed three distinct, new sites of tumor in the patient's right temporal lobe.

By Barbara Bronson GrayTUESDAY, Feb. 19 (HealthDay News) Neurosurgeons report that they harnessed the power of fluorescent light to illuminate a brain tumor so the entire growth could be removed.

Why do tumor cells respond differently to the fluorescent drug than the body's other cells do? Their metabolism involves porphyrin, which has a tremendous ability to absorb light, Berger explained. Porphyrin is an organic compound, like the pigment in red blood cells. The pill used in the case report is derived from porphyrin.
