Treating breast cancer with "MammoSite" study

Treating breast cancer with MammoSite resulted in a low risk of complications and was generally well tolerated, according to a University of Pittsburgh School of Medicine study presented today at the 47th annual meeting of the American Society for Therapeutic Radiology and Oncology (ASTRO) in Denver.

Less invasive surgery effective in treatment of reflux disease

Laparoscopic (minimally invasive) surgery to treat severe reflux disease was effective in relieving symptoms and was associated with high rates of patient satisfaction five years after the procedure, according to a study in the October issue of Archives of Surgery.

Men who smoke cigarettes may experience a significant decline in their capacity to father a child

Sperm from nearly two-thirds of the chronic smokers in the study failed a special test that measures the ability of sperm to fertilize an egg. On average, those men showed a 75 percent decline in fertilizing capacity when compared to nonsmokers. Lead researcher Loni Burkman, Ph.D., presented the results today (Oct. 17, 2005) at the American Society of Reproductive Medicine annual meeting in Montreal, Quebec.

New tool that may prove to be invaluable for investigating the long-term mutagenic effects of chemotherapy and radiation

Scientists have developed a new tool that may prove to be invaluable for investigating the long-term mutagenic effects of chemotherapy and radiation, therapies that are widely used for the treatment of cancer.

Breast magnetic resonance imaging helps doctors select best treatment for early breast cancers

Breast magnetic resonance imaging enhances patient selection for accelerated, partial breast irradiation by detecting previously unsuspected, microscopic lesions within the breast, according to a study presented October 17, 2005, at the American Society for Therapeutic Radiology and Oncology's 47th Annual Meeting in Denver.

New genetic discovery may help explain why some people develop high blood pressure and others don't

It also gives new insight into how the kidneys govern the balance of salt in the body, a crucial task for regulating blood pressure. And, it reveals how a gene already linked to behavior and mental health can play a role in the body, as well as the brain.

Accelerated partial breast irradiation using balloon brachytherapy is an excellent option for women with early breast tumors

A new method of radiation -- accelerated partial breast irradiation using balloon brachytherapy -- makes it more convenient for breast cancer patients to receive radiation therapy after surgery and appears to be safe, offer good cosmetic results, and keep cancer from coming back, according to four-year results of an ongoing study presented October 17, 2005, at the American Society for Therapeutic Radiology and Oncology's 47th Annual Meeting in Denver.

Significant step forward in the genome era

In what promises to be a significant step forward in the genome era, the National Human Genome Research Institute (NHGRI) today announced plans to devote a portion of its large-scale sequencing capacity to efforts aimed at identifying the genetic roots of specific diseases that have long eluded gene hunters.

Researchers shed light on a key molecular switch in T helper cells

Defects in immune system cells called T helper cells may lead to diseases characterized by a faulty inflammatory response such as autoimmunity and asthma. Understanding the molecular steps involved in how T helper cells mature may help researchers develop treatments for these diseases.

Abused boys may 'learn' that violence is an acceptable method of conflict resolution in the home

According to a study in the October 18 issue of the Annals of Internal Medicine, a history of childhood physical abuse may be common in men from urban settings, and these men with physical abuse histories may be more likely to commit domestic violence. The study found that the childhood abuse was primarily committed by parents, with mothers being the most frequent abusers.

Course of radiation after prostate cancer surgery improves cancer-free survival rates

Patients with advanced stage prostate cancer who receive radiation therapy immediately after surgery to remove their prostate live longer without their cancer returning than patients who do not receive radiation after surgery, according to a study presented October 17, 2005, at the American Society for Therapeutic Radiology and Oncology's 47th Annual Meeting in Denver.

Radiation therapy combined with hormone therapy after surgery is more effective in keeping the breast cancer from returning

The current standard of care for early-stage breast cancer is breast conserving surgery (lumpectomy) to remove the tumor followed by radiation and hormone therapy to kill any remaining cells.

Radiation therapy combined with chemotherapy before surgery helps patients beat rectal cancer

For patients with rectal cancer, receiving radiation therapy and chemotherapy before surgery to shrink the tumor so it can be more easily removed helps keep the cancer from coming back, according to a study presented October 17, 2005, at the American Society for Therapeutic Radiology and Oncology's 47th Annual Meeting in Denver.

New glaucoma risk calculator

High eye pressure is the leading risk factor for glaucoma, and is the only modifiable one. If glaucoma is untreated, vision loss may continue, leading to blindness in some individuals.

WWOX gene finding could lead to a new strategy for treating lung cancer

The research focused on a gene known as WWOX, which is lost or silenced in a large majority of lung cancers, and in cancers of the breast, ovary, prostate, bladder, esophagus and pancreas. The work was led by scientists at The Ohio State University Comprehensive Cancer Center - Arthur G. James Cancer Hospital and Richard J. Solove Research Institute.

New treatment for the pediatric eye cancer retinoblastoma

Investigators at St. Jude Children's Research Hospital have demonstrated in laboratory studies a new treatment for the pediatric eye cancer retinoblastoma that appears to be more effective than the current standard therapy, and more likely to prevent the recurrence of this cancer. A report on their work appears in the October 15 issue of Clinical Cancer Research.

Rett syndrome discovery

The gene responsible for Rett syndrome, a devastating neurological disease found mostly in girls, not only silences some genes but in combination with another also regulates alternative splicing, crucial to the formation of proteins -- a finding that may explain the symptoms associated with this puzzling disorder and others related to it

New type of silicone gel breast implant

A new type of silicone breast implant, currently available to women who agree to be part of a clinical study, offers breast augmentation and reconstruction patients more natural looking breasts with a low complication rate, according to a recent study in Plastic and Reconstructive Surgery, the official medical journal of the American Society of Plastic Surgeons (ASPS).

New findings on brain tumors called ependymomas

Brain tumors called ependymomas that occur in different parts of the central nervous system appear to arise from subpopulations of stem cells called radial glia cells (RGCs), according to investigators at St. Jude Children's Research Hospital. The discovery explains why some identical-looking ependymomas are actually distinctly different diseases, the researchers said.

1G8 antibody signals prostate cancer cells to stop growing and die

Researchers at UCLA's Jonsson Cancer Center have uncovered the mechanism by which an antibody blocks the growth of prostate cancer in animal models, a discovery that could pave the way for development of a new molecularly targeted therapy.
