ASTRO: DCE-MRI predicts spine tumor recurrence
October 30, 2012 -- BOSTON - By measuring plasma volume in spine tumors with dynamic contrast-enhanced (DCE) MRI, physicians can better assess treatment response even when conventional MRI results show little regression after successful radiosurgery, according to a study presented on Monday at the American Society for Radiation Oncology (ASTRO) meeting.
ASTRO: Studies affirm proton therapy's prostate cancer benefits
October 30, 2012 -- Proton therapy produces as much of a survival and therapeutic benefit as other types of treatment for prostate cancer, according to four studies scheduled to be presented at the American Society for Radiation Oncology (ASTRO) annual meeting in Boston this week.
ASTRO: No rise in heart problems after breast radiotherapy
October 29, 2012 -- Breast cancer patients who undergo radiation therapy do not have increased cardiac morbidity compared with patients undergoing radical mastectomy, indicating that routine radiation therapy is safe, according to a study presented at the American Society for Radiation Oncology (ASTRO) meeting in Boston.
ASTRO: Proton therapy outperforms IMRT for prostate cancer
October 29, 2012 -- Men undergoing proton beam therapy reported a higher quality of life immediately following treatment compared to men who received other forms of radiotherapy, according to research presented on Sunday at the American Society for Radiation Oncology (ASTRO) meeting in Boston.
Superficial RT offers alternative to surgery for skin cancers
October 29, 2012 -- This year, more than 2.8 million basal cell carcinoma and an estimated 700,000 squamous cell carcinoma skin cancers will be diagnosed in the U.S. alone, according to an estimate from the Skin Cancer Foundation. Superficial radiation therapy (RT) is an emerging option for many of these patients.
Breast brachytherapy may cause more complications
October 25, 2012 -- Breast brachytherapy has become increasingly popular for older and elderly women with early-stage breast cancer, but they may wish to think twice before selecting this treatment, based on a study published in the Journal of Clinical Oncology.
10-year prostate cancer outcomes show rad therapy's benefit
October 19, 2012 -- Ten-year clinical outcomes for prostate cancer patients participating in a trial comparing postoperative radiotherapy with observation only show that patients who were irradiated had significantly improved biochemical progression-free survival and local control.
Learning from errors boosts QA in radiation therapy
October 16, 2012 -- Establishing a successful radiotherapy quality assurance (QA) program and a department-wide culture of safety is challenging. Sustaining it can be achieved with an incident learning system, as explained in an article published online in Practical Radiation Oncology.
Hybrid linac-MRI tracks motion during radiotherapy
October 8, 2012 -- Real-time tumor tracking could prove invaluable for radiotherapy of moving targets such as lung tumors. Using MRI for such tracking provides position verification without ionizing radiation. Researchers recently discussed the latest results of a prototype hybrid linac-MRI system being developed at the Cross Cancer Institute in Canada.
Real-time dose monitoring tool enhances VMAT radiotherapy QA
October 3, 2012 -- Radiation oncology departments expect their linear accelerators to delivery radiation doses accurately as programmed. While it's possible to check planned dose delivery after treatment, safety for patients is increased if dose data can be monitored in real-time.
Fasting enhances response of glioma to radiation therapy
October 3, 2012 -- Controlled fasting improves the effectiveness of chemotherapy and radiation therapy in mice with aggressive brain tumors, extending their survival, according to research published in September in PLOS One.
Risk markers found for erectile dysfunction after RT
October 1, 2012 -- Genetic markers associated with the development of erectile dysfunction in prostate cancer patients following radiation therapy (RT) have been identified, according to a study published online on September 27 in the International Journal of Radiation Oncology, Biology, Physics.
Study predicts cancer care costs to double by 2020
September 25, 2012 -- Cancer-related medical costs are expected to more than double in some U.S. states within eight years, according to a study published in the September issue of the American Journal of Managed Care.
ASCO BSC: Long-term APBI outcomes are favorable
September 19, 2012 -- Long-term outcomes of breast cancer patients participating in a clinical trial evaluating the effectiveness of accelerated partial-breast irradiation (APBI) continue to be favorable, according to a presentation in San Francisco last week at the American Society of Clinical Oncology's (ASCO) Breast Cancer Symposium (BCS).
Exploiting log files for optimal radiotherapy QA
September 18, 2012 -- Quality assurance (QA) of intensity-modulated radiation therapy (IMRT) is a vital component in the radiotherapy process, but current QA procedures are far from optimal. Log files produced by radiotherapy systems can be exploited to vastly improve IMRT quality assurance.
Cranial irradiation decreases NSCLC metastases
September 11, 2012 -- Cranial irradiation of patients with stage III non-small cell lung cancer (NSCLC) significantly reduces the risk of developing brain metastases. However, it has no effect on survival, according to a presentation at the Chicago Multidisciplinary Symposium in Thoracic Oncology held September 6-8.
Meningioma patients report good QOL years after radiotherapy
September 10, 2012 -- A patient diagnosed with meningioma of the skull base can have several treatment options, all with known risks. Radiation therapy may be the more palatable option, maintaining or improving quality of life (QOL), according to a new study published in Radiotherapy and Oncology.
