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.

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.

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.

Skin cancer facts

Up to two-thirds of all cancers may be prevented through dietary and lifestyle changes. In the case of skin cancer, this could not be more true.

Doctors able to predict recurrence of high-risk breast cancers

International researchers have developed a prediction model to assist doctors in determining the chance of recurrence of cancer in high-risk breast cancer patients who have undergone a mastectomy followed by radiation therapy.

Call to speed access to innovative advances for all breast cancer patients

Breast cancer specialists and advocates at the 5th European Breast Cancer Conference (EBCC-5) called for patients to have equal and speedy access to new breast cancer treatments and procedures, as soon as they are validated by comparative clinical trials.

Salvage radiation therapy for PSA recurrence following radical prostatectomy

Salvage radiation therapy to the prostatic fossa is often employed in patients with rising PSA after radical prostatectomy (RP). Interestingly, only 25% of men with rising PSA after RP have a positive prostatic fossa biopsy, yet 70% of men with a negative biopsy will have their PSA decline to undetectable levels following salvage external beam radiotherapy.

Donepezil (Aricept) helps cognitive function in brain tumor patients after radiation

A drug that is marketed to treat Alzheimer's disease also improves cognitive function, mood and quality of life in brain tumor patients following radiation therapy, according to a research team at Wake Forest University Baptist Medical Center.

Low PSA score after radiation can predict prostate cancer return

A consortium of prostate cancer experts have discovered, through a clinical investigation, that prostate cancer patients who have a lower prostate specific antigen (PSA) score after radiation therapy to treat their cancer are less likely to have their prostate cancer return or spread to other parts of their body than patients with a higher PSA score.

The transcription factor MEF/ELF4 regulates the quiescence of primitive hematopoietic cells

Scientists have uncovered new information about what orchestrates the complex balance between blood stem cells and mature blood cells, a relationship that is often disrupted in leukemia.
