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.

Trastuzumab results promising for HER-2 positive breast cancer patients

Researchers have shown that patients who receive trastuzumab at the same time as post-chemotherapy radiation treatments for HER-2 positive breast cancer have no more risk for major side effects or complications than those who do not receive the drug.

Exercise is emerging as a new therapeutic weapon to tackle cancer

When individuals with breast or prostate cancer followed a moderate, home-based exercise program using resistance bands and walking, the patients had less fatigue during radiation treatments, greater strength and could walk farther and faster in only four weeks, researchers discovered in a pilot study.

Hormonal treatments reduce risk of cancer returning

Women diagnosed with breast cancer who carry a certain genetic mutation can have breast-sparing surgery but should consider hormonal treatments to reduce their risk of cancer returning.

Addition of gemcitabine to standard postoperative treatment increased pancreatic cancer patients' survival by 50 percent

Adding the cancer-fighting drug gemcitabine to standard therapy after surgery significantly improves survival for patients with the most common form of pancreatic cancer, according to a new multicenter study led by a University of Maryland radiation oncologist.

Taxotere combined with standard chemotherapy improves survival in advanced head and neck cancers

The addition of docetaxel (Taxotere) to an initial chemotherapy regimen for inoperable head and neck cancers reduced mortality by nearly 30 percent over three years following treatment compared to the standard two-drug combination.

Breast radiation device associated with complications

Doctors in New England have discovered that patients receiving accelerated-partial breast radiation therapy using a balloon brachytherapy system after lumpectomy for breast cancer can develop seroma, the retaining of fluid, in their breast which can require aspiration or make monitoring them by physical exam more difficult.

Effectiveness of radiation therapy for older women with early breast cancer

Elderly women with early-stage breast cancer had a lower risk of recurrence when they were treated with radiation therapy, according to a study in the Journal of the National Cancer Institute.

Gene family of potential tumor inhibitors identified

Proteins from a newly discovered family of genes, LRIG, function as a retardant for a protein that is important to tumor cells. It is probably this mechanism that lends the gene family its inhibiting effect on cancer tumors.

First animal model that mimics human head and neck cancer

An Oregon Health & Science University Cancer Institute research laboratory has developed a novel mouse model designed specifically to study the often devastating head and neck squamous cell cancers.

Promising chemo, therapeutic viruses, cutting-edge surgery debut at M. D. Anderson Cancer Center

Brain tumor specialists at The University of Texas M. D. Anderson Cancer Center are poised on the brink of a new era.

Breast removal not the only treatment option for non-invasive breast cancer

Breast conserving surgery, long known to be successful at treating the more common invasive cancer, can also be effective for this pre-invasive condition, according to a new study from researchers at the University of Michigan Comprehensive Cancer Center.

New procedure to treat fractured vertebrae caused by spinal tumors

A radiologist at the University of California, San Diego (UCSD) School of Medicine has developed a new procedure to treat fractured vertebrae caused by spinal tumors, a procedure that may decrease the risk of complications, which are experienced by 5 to 10% of patients with malignant tumors of the spine.

Breast conserving surgery is a good option for early breast cancer

For women diagnosed with a type of non-invasive breast cancer, removing the breast is not the only treatment option.

Does age matter in selection of treatment for men with early-stage prostate cancer?

For men under the age 55 with localized prostate cancer, external beam radiation may be an effective alternative to both conservative and more invasive treatments, according to a new study.

Obtaining and documenting informed patient consent prior to surgery

Obtaining and documenting informed patient consent prior to surgery is of vital importance, but both the process and documentation of consent can be inadequate.

Polymer-based therapy for breast cancer

Women who undergo surgery for breast cancer followed by radiation therapy often experience breast deformities that can only be corrected through reconstructive surgery.

3 May 2006

Initial experience of FDG-PET/CT guided IMRT of head and neck carcinoma

Doctors have discovered that combining images derived from positron emission tomography and computed tomography in the planning and delivery of radiation treatment for patients with head and neck cancer leads to more accurate delivery of the radiation dose and an increased chance for survival.

Surgical robot makes prostate removal safe for obese men

The use of a robotic system could make surgery for prostate cancer an option for thousands of obese men who might otherwise be turned down, report researchers from the University of Chicago in the April 2006 issue of the journal Urology.

New discovery could help improve some forms of chemotherapy

The research looked at XPB helicase from an archaea, a single cell organism similar to bacteria. Helicases are enzymes that unwind or separate the strands of the nucleic acid double helix, an action that is critical to transcription and nucleotide excision repair (NER), as well as other cell processes.

Fullerene shows promise in reducing radiation side effects

Using transparent zebrafish embryos, researchers at Jefferson Medical College in Philadelphia have shown that a microscopic nanoparticle can help fend off damage to normal tissue from radiation.
