Georgetown Lombardi researchers present new findings on head & neck cancers

2012-01-30
(Press-News.org) WASHINGTON, DC – Research physicians from Georgetown Lombardi Comprehensive Cancer Center will present new data about a complex group of cancers known as head and neck cancers at the Multidisciplinary Head and Neck Cancer Symposium, January 26 through 28, in Phoenix, Arizona.

Should patients with HPV+ head and neck cancers receive less chemotherapy? Georgetown researchers are examining a hypothesis about whether HPV+ patients with a head and neck cancer should receive more or less chemotherapy. "Given the rising number of patients with HPV-caused head and neck cancers, we need to find the right way to treat and cure, this disease," explains John Deeken, M.D., director of head and neck medical oncology at Georgetown Lombardi. "Some argue that we should decrease the intensity of treatment given how well HPV-positive cancers respond to treatment. Our research suggests the opposite -- that intensifying therapy in high-risk HPV-positive patients might well increase the cure rate of this disease. Clearly additional clinical studies are warranted to further test our findings." (See study abstract below.)

Examining a rare sequel of head and neck cancer – axillary node metastasis In a separate study, researchers are studying an unusual occurance linked to head and neck tumors involving metastasis in the axillary nodes. "It is postulated that this can be secondary to tumor blockage at the jugulo-subclavian junction and/or fibrosis of the cervical lymphatics following surgery or radiation therapy resulting in retrograde lymphatic flow," says Richard H. Comstock III, M.D, a 4th-year resident in the department of otolaryngology at MedStar Georgetown University Hospital. "Upon reviewing the patients in our series we found that they all had manipulation of their neck lymphatics with either surgery or radiation which we believe played a role in the development of axillary metastasis. In addition we present the only known case of axillary metastasis from a squamous cell skin malignancy." Comstock adds, "Clinicians should be aware of this potential complication of head and neck cancer an screen high risk patients accordingly." (See study abstract below.) ### The findings presented at this conference are from a limited peer-reviewed abstract. The data should be considered as preliminary until they are published in a peer-reviewed scientific or medical journal. The Multidisciplinary Head and Neck Cancer Symposium is co-sponsored by the American Society for Clinical Oncology, American Society for Radiation Oncology, American Head and Neck Society and the Society of Nuclear Medicine.

About Georgetown University Medical Center Georgetown University Medical Center is an internationally recognized academic medical center with a three-part mission of research, teaching and patient care (through MedStar Health). GUMC's mission is carried out with a strong emphasis on public service and a dedication to the Catholic, Jesuit principle of cura personalis -- or "care of the whole person." The Medical Center includes the School of Medicine and the School of Nursing & Health Studies, both nationally ranked; Georgetown Lombardi Comprehensive Cancer Center, designated as a comprehensive cancer center by the National Cancer Institute; and the Biomedical Graduate Research Organization (BGRO), which accounts for the majority of externally funded research at GUMC including a Clinical Translation and Science Award from the National Institutes of Health. In fiscal year 2010-11, GUMC accounted for 85 percent of the university's sponsored research funding.

Rap music powers rhythmic action of medical sensor

Rap music powers rhythmic action of medical sensor
2012-01-30
WEST LAFAYETTE, Ind. - The driving bass rhythm of rap music can be harnessed to power a new type of miniature medical sensor designed to be implanted in the body. Acoustic waves from music, particularly rap, were found to effectively recharge the pressure sensor. Such a device might ultimately help to treat people stricken with aneurisms or incontinence due to paralysis. The heart of the sensor is a vibrating cantilever, a thin beam attached at one end like a miniature diving board. Music within a certain range of frequencies, from 200-500 hertz, causes the cantilever ...

How seawater could corrode nuclear fuel

How seawater could corrode nuclear fuel
2012-01-30
Japan used seawater to cool nuclear fuel at the stricken Fukushima-Daiichi nuclear plant after the tsunami in March 2011 -- and that was probably the best action to take at the time, says Professor Alexandra Navrotsky of the University of California, Davis. But Navrotsky and others have since discovered a new way in which seawater can corrode nuclear fuel, forming uranium compounds that could potentially travel long distances, either in solution or as very small particles. The research team published its work Jan. 23 in the journal Proceedings of the National Academy ...

Believing the impossible and conspiracy theories

2012-01-30
Los Angeles, CA - Distrust and paranoia about government has a long history, and the feeling that there is a conspiracy of elites can lead to suspicion for authorities and the claims they make. For some, the attraction of conspiracy theories is so strong that it leads them to endorse entirely contradictory beliefs, according to a study in the current Social Psychological and Personality Science (published by SAGE). People who endorse conspiracy theories see authorities as fundamentally deceptive. The conviction that the "official story" is untrue can lead people to believe ...

IRCM researchers fuel an important debate in the field of molecular biology

2012-01-30
Dr. François Robert, molecular biology researcher at the Institut de recherches cliniques de Montréal (IRCM), and his team confirmed that the phosphorylation of RNA polymerase II, a key enzyme in the process of gene expression, is uniform across all genes. This discovery, which contributes to numerous debates on the topic within the scientific community, will be published tomorrow in the scientific journal Molecular Cell. Phosphorylation, or the addition of phosphate to a molecule, is one of the most important regulation mechanisms for cells. It allows, among other things, ...

A multi-university research group which includes several University of Notre Dame faculty and graduate students, has recently published a paper detailing new work on the analysis and dating of human bruises. The research, which is funded by the Gerber Foundation, will have particular application to pediatric medicine, as bruise age is often key evidence in child abuse cases. Using a combination of modeling and spectroscopy measurements, the researchers have advanced our understanding of the changing composition of aging bruises and developed new tools for detailed biomedical ...

Scripps research scientists illuminate cancer cells' survival strategy

Scripps research scientists illuminate cancer cells survival strategy
2012-01-30
LA JOLLA, CA -- A team led by scientists at The Scripps Research Institute has discovered key elements of a strategy commonly used by tumor cells to survive when they spread to distant organs. The finding could lead to drugs that could inhibit this metastasis in patients with tumors. A cell that breaks away from the primary tumor and finds itself in the alien environment of the bloodstream or a new organ, normally is destroyed by a process known as apoptosis. But tumor cells that express high levels of a certain surface protein are protected from apoptosis, greatly enhancing ...

Living on the edge: An innovative model of mangrove-hammock boundaries in Florida

2012-01-30
CORAL GABLES, FL. -- The key to understanding how future hurricanes and sea level rise may trigger changes to South Florida's native coastal forests lurks below the surface, according to a new model linking coastal forests to groundwater. Just inland from the familiar mangroves that line the coasts lie hardwood hammocks that are sensitive to salinity changes in water found in the soils. University of Miami (UM) Ecologist Donald L. DeAngelis, who is also a researcher for the U.S Geological Survey (USGS), has worked with collaborators to develop a novel computer model describing ...
