Radiation Therapy News and Research

RSS

Radiation therapy (also called radiotherapy, x-ray therapy, or irradiation) is the use of a certain type of energy (called ionizing radiation) to kill cancer cells and shrink tumors. Radiation therapy injures or destroys cells in the area being treated (the “target tissue”) by damaging their genetic material, making it impossible for these cells to continue to grow and divide. Although radiation damages both cancer cells and normal cells, most normal cells can recover from the effects of radiation and function properly. The goal of radiation therapy is to damage as many cancer cells as possible, while limiting harm to nearby healthy tissue.

African-American women breast cancer sufferers often refuse chemotherapy and radiation therapy

A new study finds that nearly one in four African American women with late stage breast cancer refused chemotherapy and radiation therapy, potentially life saving therapies.

Low oxygen levels in prostate tumors can predict recurrence

Fox Chase Cancer Center researchers have discovered that low-oxygen regions in prostate tumors can be used to predict a rise in prostate-specific antigen (PSA) levels, a marker of tumor recurrence in prostate cancer.

Genetic signature may predict patient response to GIST therapy

Researchers at Fox Chase Cancer Center uncovered a genetic pattern that may help predict how gastrointestinal stromal tumor (GIST) patients respond to the targeted therapy imatinib mesylate (Gleevec). Moreover, their findings point to genes that could be suppressed in order to make these tumors respond more readily to imatinib.

New therapy improves chances of living disease-free with neuroblastoma

A phase III study has shown that adding an antibody-based therapy that harnesses the body's immune system resulted in a 20 percent increase in the number of children living disease-free for at least two years with neuroblastoma.

Research looks at advanced radiation therapy technique for pancreatic cancer

According to the American Cancer Society, pancreatic cancer is the fourth leading cancer killer in the country, with more than 42,000 new cases expected to be diagnosed this year and more than 35,000 deaths. In New Jersey alone, 1,000 deaths are estimated from the disease, which only has a five-year, five-percent survival rate.

Loss of stromal protein major new prognostic factor in patients with breast cancer

Reporting online in the American Journal of Pathology, researchers from the Kimmel Cancer Center at Jefferson have implicated the loss of a stromal protein called caveolin-1 as a major new prognostic factor in patients with breast cancer, predicting early disease recurrence, metastasis and breast cancer patient survival.

AUA counters mainstream recommendations with new best practice statement on PSA testing

The American Urological Association (AUA) today issued new clinical guidance - which directly contrasts recent recommendations issued by other major groups - about prostate cancer screening, asserting that the prostate-specific antigen (PSA) test should be offered to well-informed, men aged 40 years or older who have a life expectancy of at least 10 years.

Study links arm/hand swelling to number of lymph nodes removed during breast cancer surgery

In older breast cancer survivors, the number of lymph nodes removed during surgery and the presence of cancer in the lymph nodes were the two factors most directly linked to the development of lymphedema, swelling of the arm and hand, according to a study from the Medical College of Wisconsin's Center for Patient Care and Outcomes Research in Milwaukee, Wisconsin.

Radiation device in the breast reduces complications for early stage breast cancer patients

A new study shows that the SAVI™ applicator, a small, expandable device inserted inside the breast to deliver partial breast irradiation, carries a low infection risk, a potential complication of such devices.

Grapefruit juice boosts efficacy of drug rapamycin

In a small, early clinical trial, researchers at the University of Chicago Medical Center have found that combining eight ounces of grapefruit juice with the drug rapamycin can increase drug levels, allowing lower doses of the drug to be given.

Acupuncture relieves symptoms of xerostomia

Twice weekly acupuncture treatments relieve debilitating symptoms of xerostomia - severe dry mouth - among patients treated with radiation for head and neck cancer, researchers from The University of Texas M. D. Anderson Cancer Center report in the current online issue of Head & Neck.

Omega-3 fatty acids may help cancer patients undergoing major operations

New research from Trinity College Dublin published in this month's Annals of Surgery points to a potentially significant advance in the treatment of patients undergoing major cancer surgery.

Monoclonal antibody cancer therapy

The strategy of using monoclonal antibodies for cancer treatment was first described in the late 1970s with the promise that they could be developed into therapies that were highly specific to cancer cells, killing them with few or no side effects.

New 90-second radiotherapy therapy called RapidArc

The University of Alabama at Birmingham (UAB) this month became the first U.S. medical center to offer a speedier cancer radiation therapy.

Link between certain types of radiation therapy and fertility problems in women

In female cancer patients of reproductive age, radiation treatment directly to the ovaries should be avoided because there is a direct relationship between certain types of radiation therapy and fertility problems, according to a review in the April 1 issue of the International Journal of Radiation Oncology*Biology*Physics , the official journal of the American Society for Radiation Oncology (ASTRO).

Brain vessel malformations - intervention or a hands-off approach?

Individuals diagnosed with a brain arteriovenous malformation (BAVM) -- an abnormal tangle of arteries and veins -- are at increased risk of vessel rupture and bleeding that can cause permanent brain damage.

3-drug chemotherapy combo increases organ preservation in patients with larynx cancer

Patients with larynx cancer who received a three-drug combination of docetaxel, cisplatin and 5-fluorouracil (TPF) during induction chemotherapy were more likely to retain larynx function than were patients treated with cisplatin and 5-fluoruracil (PF) alone, according to data from a randomized controlled trial in the March 24 online issue of the Journal of the National Cancer Institute.
