Radiation therapy (in North America), or radiotherapy (in the UK and Australia) also called radiation oncology, and sometimes abbreviated to XRT, is the medical use of ionizing radiation as part of cancer treatment to control malignant cells (not to be confused with radiology, the use of radiation in medical imaging and diagnosis).

Study examines increased use of new technologies for prostate cancer treatment

Use of advanced treatment technologies for prostate cancer, such as intensity-modulated radiotherapy and robotic prostatectomy, has increased among men with low-risk disease, high risk of noncancer mortality, or both, a population of patients who are unlikely to benefit from these treatments, according to a study in the June 26 issue of JAMA.

Dosimetry based on 3-D medical images estimates possible dose for targeted RIT in blood cancer patients

Outcomes can be bleak for non-Hodgkin lymphoma (NHL), a cancer that develops in the white blood cells of the immune system. Accurate estimation of radiation absorbed dose in radioimmunotherapy (RIT) based on state-of-the-art 3D imaging could lead to more personalized and effective treatments to improve patients' chances of living longer without progression of their cancer, say researchers at the Society of Nuclear Medicine and Molecular Imaging's 2013 Annual Meeting.

Researcher improves segmentation technique of PET images

Elena Prieto-Azkarate, a graduate in Telecommunications Engineering at the NUP/UPNA-Public University of Navarre and member of the Nuclear Medicine Service of the University College Hospital of Navarre, has implemented 12 algorithms to process medical images produced by means of PET (Positron Emission Tomography).

International clinical study shows that BioProtect Balloon Implant has potential to reduce rectal injury

Several years ago, Virginia Commonwealth University Massey Cancer Center became the first center in the United States to test an Israeli-invented device designed to increase the space between the prostate and the rectum in prostate cancer patients undergoing radiation therapy.

Aaxillary lymph node dissection and radiotherapy provide excellent regional control for patients with breast cancer

Final analysis of the EORTC 10981-22023 AMAROS (After Mapping of the Axilla: Radiotherapy Or Surgery?) trial has shown that both axillary lymph node dissection and axillary radiotherapy provide excellent regional control for breast cancer patients with a positive sentinel node biopsy

MRIgFU ablation therapy reduces pain in 67% of patients with bone tumors

Patients with cancer that has spread to their bones are often treated with radiation therapy to reduce pain. But if that treatment doesn't work, or can't be used again, a second, effective option now exists.

Porter Cancer Care Center to use new image-guided radiotherapy system for cancer treatment

Starting June 2013, the Porter Cancer Care Center at Porter Adventist Hospital becomes one of the few facilities in the country to offer highly advanced radiation therapy and radiosurgery cancer treatment options using the new Varian TrueBeam image-guided radiotherapy system.

Radiotherapy: First choice treatment for low-grade glioma

In a large, international, randomized trial, initial radiotherapy was compared to temozolomide chemotherapy. A statistically significant difference between the two treatment strategies was not observed for progression-free survival, although radiotherapy was numerically favored. However, molecular tumor characterization may allow the treatment approach to be personalized and one or the other treatment modality to be selected.

St James's Institute of Oncology orders two Versa HD systems to improve patient care

St James's Institute of Oncology, a leading radiotherapy center in the UK, recently ordered two Versa HD™ systems, an advanced linear accelerator designed to improve patient care and treat a wide range of tumors throughout the body.

Research suggests that IMRT may not be more effective in patients who had prostatectomy

Intensity-modulated radiation therapy has become the most commonly used type of radiation in prostate cancer, but research from the University of North Carolina suggests that the therapy may not be more effective than older, less expensive forms of radiation therapy in patients who have had a prostatectomy.

No significant benefit differences between IMRT and CRT therapies after prostatectomy

Use of the newer, more expensive intensity-modulated radiotherapy (IMRT) and use of the older conformal radiotherapy (CRT) after surgical removal of all or part of the prostate gland were associated with similar morbidity and cancer control outcomes, according to a study published Online First by JAMA Internal Medicine, a JAMA Network publication.

Researchers say that receiving cancer radiation therapy late in the day may minimize hair loss

Discovering that mouse hair has a circadian clock - a 24-hour cycle of growth followed by restorative repair - researchers suspect that hair loss in humans from toxic cancer radiotherapy and chemotherapy might be minimized if these treatments are given late in the day.

Researchers develop new mouse model to discover gene pathways that drive MPNST

University of Minnesota Medical School researchers from the Masonic Cancer Center, University of Minnesota, in partnership with the University's Brain Tumor Program, have developed a new mouse model of malignant peripheral nerve sheath tumors that allow them to discover new genes and gene pathways driving this type of cancer.

Loss of Merlin protein leads to abnormal growth of tumours

A study led by researchers from Plymouth University Peninsula Schools of Medicine and Dentistry has for the first time revealed how the loss of a particular tumour suppressing protein leads to the abnormal growth of tumours of the brain and nervous system.
