This 14 year old girl suffers from a huge tumor in her face...
WINSTON-SALEM, NC - On November 30, physicians at the Gamma Knife Center at Wake Forest University Baptist Medical Center performed Leksell Gamma Knife stereotactic radiosurgery on one of the world's tallest men to treat a pituitary tumor and restore his potential for a promising basketball career.
Sun Ming Ming, a 23 year-old from China, came to the United States in 2005 hoping to be drafted by the National Basketball Association (NBA). At 7'9" his prospects looked good.
Though he was eligible for the draft, he lacked stamina, strength and speed. He was diagnosed with a tumor on his pituitary gland that was responsible for his extraordinary height as well as his lack of performance. The tumor caused the pituitary gland, which is located near the middle of the brain, behind the eyes and nose, to overproduce growth hormone.
"Ming's tumor is challenging in that it is located dangerously close to the optic nerves," said Volker W. Stieber, M.D., the radiation oncologist who is co-director of the Gamma Knife Center. Traditional surgery last year at a California hospital removed the majority of the tumor but enough tumor tissue remained that it continues to overproduce growth hormone at a level that will ultimately be fatal if he does not receive additional treatment.
"The Gamma Knife surgery is expected to stop the abnormal hormone production by destroying the residual tumor tissue which could not be removed by conventional invasive surgery," said Stieber.
The Gamma Knife Center at Wake Forest University Baptist Medical Center has one of the most experienced Gamma Knife treatment teams in the country at one of the nation's busiest Gamma Knife centers.
Gamma Knife radiosurgery is a non-invasive procedure in which a single, highly targeted dose of radiation is delivered through the skull to the tumor. The Leksell Gamma Knife is manufactured in Sweden by Elekta AB. The device focuses 201 beams of gamma radiation directly upon the targeted tissue, thus sparing the healthy surrounding brain tissue from radiation. The tissue is targeted with pinpoint accuracy using highly sophisticated imaging and three dimensional planning technologies.
Gamma Knife radiosurgery is most often performed as an outpatient procedure and Sun Ming Ming is expected to be released that afternoon. The effect of the treatment on stopping the production of new tumor cells is almost immediate; his doctors expect that it will take at least one year for his hormone levels to return to completely normal levels.
Children $ Tumors from Cell Phones?
Treating cancer often involves the use of high-tech equipment or spending hours at a time in the hospital. Now a new approach to controlling brain tumors is remarkably simple. For some patients, it’s as easy as taking a pill.
As the word “asbestos” stands for
inextinguishable property, the word
“mesothelioma” specifically means tumor.
The Pediatric Brain Tumor Foundation (PBTF) is giving an additional $6 million grant to its research institute at Duke University, bringing total funding for the program to $12 million.
Duke will use the funds to continue to sharpen its research focus on pediatric brain tumors, which are the leading cause of cancer death in children and adolescents. Four out of 10 children with a brain tumor die within five years of diagnosis, a statistic the PBTF intends to improve through its research institute program.
"The goal of this grant is to translate our understanding of childhood brain tumors into novel, less-invasive treatment methods," said Dianne Traynor, PBTF Director of Research Funding and Advocacy.

Intensity Modulated Radio Therapy Targets Cancer and Helps Minimize Treatment Side Effects
Despite constant advancements in cancer research and treatment, the science of eliminating tumors remains challenging. With many traditional radiation treatments, the exact position of a tumor and the proper dose of radiation needed can be difficult to determine and even harm healthy tissue.
Now a new target treatment system may make tracking tumors easier. Intensity modulated radio therapy, like Siemens' Artiste, finds and targets tumors giving them the proper dose of radiation each time. By using multiple sets of beams from multiple areas and modulating each beam to allow different energy at different parts of the beam, doctors can calculate doses so that they treat the tumors but exclude healthy tissue.
Because a tumor can change position within a patient from one day to the next, identifying the exact location is crucial. Intensity modulated radio therapy puts the radiation only where it's needed helping to minimize patient side effects.

Dr. Gail Rosseau, board-certified neurosurgeon and U.S. Surgeon General candidate, discusses the prevalence and most common symptoms related to pituitary tumors. Vision disturbances and symptoms related to the overproduction of hormones are two of the most serious symptoms which may require a surgical intervention. Surgery for pituitary tumors is performed through the nose using a small endoscope to extract the tumor with no visible incision. Surgery for pituitary tumors, in experienced hands such as Dr. Rosseau’s, typically takes 2-3 hours and most patients stay in the hospital for 2-3 days.
