Majority of women with early-stage breast cancer in U.S. receive unnecessarily long courses of radiation

“Hypofractionated radiation is infrequently used for women with early-stage breast cancer, even though it’s high-quality, patient-centric cancer care at lower cost,” said lead author Bekelman, an assistant professor of Radiation Oncology, Medical Ethics and Health Policy at the University of Pennsylvania’s Perelman School of Medicine and Abramson Cancer Center. “It is clinically equivalent to longer duration radiation in curing breast cancer, has similar side effects, is more convenient for patients, and allows patients to return to work or home sooner.” Shown to reduce local recurrence and improve overall survival after breast conserving surgery, conventional whole breast radiation, given daily over five to seven weeks, has been the mainstay of treatment in the U.S. for women for decades…

Older breast cancer patients still get radiation despite limited benefit

The study suggests that doctors and patients may find it difficult to withhold treatment previously considered standard of care, even in the setting of high quality data demonstrating that the advantages are small. “The onus is on physicians to critically analyze data to shape our treatment recommendations for patients, weighing the potential toxicities of treatment against clinical benefit,” said Rachel Blitzblau, M.D., Ph.D., the Butler Harris Assistant Professor of Radiation Oncology at Duke University Medical Center. Blitzblau was the senior author of a study published online Dec. 8, 2014, in the journal Cancer. …

Ovarian cancer patients may benefit from pelvic radiotherapy

“Despite the intense therapeutic and surgical regimen typically used to treat ovarian cancer, outcomes remain poor,” said William Small Jr., MD, chair, Department of Radiation Oncology, LUHS. “This study provided encouraging preliminary results for the use of RT in women with ovarian cancer.” The study evaluated 56 patients with ovarian clear cell adenocarcinoma (CCA), an aggressive form of ovarian cancer that is more likely to be resistant to chemotherapy and to have a poorer prognosis than other forms of this disease. …

Technology developed to improve lung cancer detection, treatment

John Roeske, PhD, and colleagues presented how they developed and evaluated the technology at the recent annual meeting of the American Society for Therapeutic Radiology and Oncology. Their approach uses dual-energy imaging combined with fluoroscopy to view tumors during radiation therapy. This technology does not require an X-ray that produces both high-and low-energy images. Existing hardware can be used to eliminate visuals of the ribs and other bones making it easier to see the tumor…

Image Guided Radiation Therapy Is Commonly Used to Ensure Accuracy in Treating Pediatric Tumors

IGRT is the process of using frequent imaging, typically performed in the treatment room prior to radiation delivery, throughout a patient’s course of radiation therapy treatment to improve localization of the target and normal structures, which allows for more precise and accurate radiation delivery. IGRT is a common practice in both photon (traditional radiation therapy) and proton therapy to treat tumors close to sensitive structures and organs or in areas of the body prone to movement or change in shape. This study, “Practice patterns of photon and proton pediatric image guided radiation treatment: Results from an International Pediatric Research Consortium,” evaluates the use of IGRT in treatment planning for pediatric cancers in an international consortium comprised of seven institutions using either photon or proton therapy with dedicated pediatric expertise. Choosing optimal IGRT regimens that spare healthy tissue and organs is a particular concern for pediatric patients to help prevent potential late effects associated with the distribution of the radiation dose and the total radiation dose the patient receives. …

Body position in breast cancer radiation treatment matters, experts say — ScienceDaily

Dr. Julia White of Ohio State’s Comprehensive Cancer Center — James Cancer Hospital and Solove Research Institute has helped develop a modified treatment board that allows patients to lie comfortably on their stomachs while the breast tissue falls away from the chest wall, allowing the radiation to target the cancer. Traditionally, women who undergo radiation therapy lie on their backs in the supine position. …

Focus on treatment costs, value: Less radiation for elderly women with early breast cancer — ScienceDaily

The study, using a national database of more than 100,000 women treated during the last decade, found that today nationally radiation oncologists are less likely to use radiotherapy in women older than 70 with early-stage estrogen-receptor-positive breast cancer and that when they do, treatment is appropriately less-intensive. This follows a randomized trial demonstrating low rates of recurrence in women who don’t receive radiotherapy after lumpectomy, provided they take endocrine therapy. This confirms radiation oncologists are responding to a growing impetus to keep medical practices current and cost-effective, said first author Charles Rutter, M.D., a radiation oncology resident in Yale’s School of Medicine. …

Benefit of endocrine therapy in elderly women with low risk hormone receptor positive breast cancer? — ScienceDaily

The results, which Fox Chase researchers presented at the American Society for Radiation Oncology’s 56th Annual Meeting on September 14, suggest that low-risk patients over 65 years old with small tumors may achieve comparable survival after treatment with adjuvant radiation therapy alone — without undergoing endocrine therapy. …

Chemotherapy and stereotactic ablative radiation consecutively may be promising for patients with advanced pancreatic cancer

Surgery is the only potentially curative therapy for individuals with pancreatic ductal adenocarcinoma (PDA), the most common type of pancreatic cancer. However, pancreatic cancer is often diagnosed at an advanced stage, making surgical removal of the tumor or the organ challenging, if not impossible. …
