Imaging biomarkers show promise for cancer treatment response
February 8, 2013 -- Imaging biomarkers show promise as tools to assess patient response to chemotherapy and radiation therapy. Research on the use of biomarkers for brain tumors and esophageal cancers was presented in scientific sessions at the Cancer Imaging and Radiation Therapy Symposium, held February 8 and 9 in Orlando, FL.
Gold nanoparticles offer future potential as cancer treatment
February 7, 2013 -- Researchers have demonstrated the ability to harness powerful radioactive particles and direct them toward small cancer tumors using gold-plated nanoparticles, according to an article published online January 18 in PLOS One.
Accelerated RT with boost works well for breast cancer patients
February 6, 2013 -- Accelerated whole-breast radiation therapy (RT), which shortens radiation treatment duration by half, is proved to be as effective as conventional therapy for early-stage breast cancer patients. Whether a concomitant boost is needed remains a subject of debate among radiation oncologists due to the overall treatment's potential toxicity.
PET/CT predicts response to endorectal radiotherapy
January 30, 2013 -- PET/CT results can predict which patients will respond to high-dose-rate endorectal brachytherapy for stage II and III rectal cancer, according to a study presented at the American Society of Clinical Oncology Gastrointestinal Cancers Symposium. The results could pave the way for easier treatments and better outcomes.
Blacks treated less, die sooner from advanced colon cancer
January 29, 2013 -- When it comes to advanced metastatic colorectal cancer, blacks are less likely to be referred for treatment, less likely to receive it, and more likely to die sooner than whites, according to a study presented on Saturday at the American Society of Clinical Oncology Gastrointestinal Cancers Symposium.
Lumpectomy with RT tops mastectomy for early-stage cancer
January 28, 2013 -- Women with early-stage breast cancer sometimes opt for mastectomy rather than less radical surgery out of concern about cancer recurrence. But recurrence risk was lower for women who chose lumpectomy followed by radiation therapy (RT) compared with those who received mastectomies, according to a study published online on Monday in Cancer.
Qigong has benefits for breast cancer patients
January 25, 2013 -- Qigong, an ancient Chinese mind-body practice, reduces symptoms of depression and improves quality of life in women undergoing radiation therapy for breast cancer, according to a study published online January 25 in Cancer.
Bras aid positioning for large-breasted women during RT
January 25, 2013 -- Large-breasted women pose a challenge when radiation therapy (RT) for early-stage breast cancer is being planned and performed. Using a bra or bustier improves simulation and positioning in the supine position, according to an article published in the January issue of Practical Radiation Oncology.
AAPM issues guidelines for radiation therapy error databases
January 18, 2013 -- With the goal of improving radiation therapy safety, the American Association of Physicists in Medicine (AAPM) has published technical recommendations to aid developers of databases that are designed to track and record treatment errors and near misses.
Stereotactic radiosurgery shows promise for renal cancer
January 14, 2013 -- Stereotactic radiosurgery could be a useful treatment option for patients with localized primary renal cancer who do not have a prior history of pelvic or abdominal radiation, and for whom surgery is not appropriate, researchers in Ohio have concluded.
Beta-blockers improve outcomes of NSCLC patients
January 9, 2013 -- In a large study from MD Anderson Cancer Center, patients with non-small cell lung cancer (NSCLC) survived longer if they took beta-blockers while receiving treatment that included radiotherapy. Results were published online January 8 in the Annals of Oncology.
SBRT halves cost vs. IMRT for prostate cancer
January 3, 2013 -- As members of Congress grapple over ways to reduce the U.S. budget, the publication on December 27 in the American Journal of Clinical Oncology of a complex model analyzing the costs of radiation therapy for prostate cancer seems particularly timely.
Lymph node ratio predicts RT benefit for oral cancer
January 3, 2013 -- Radiation therapy (RT) can benefit some patients with oral cavity squamous cell carcinoma, but they can suffer acute as well as long-term toxicities. The use of lymph node ratios may help identify which patients will benefit the most, according to an article published online in Radiotherapy and Oncology.
Rad therapy doesn't help survival for stage I endometrial cancer
December 31, 2012 -- A Cochrane update evaluating radiation therapy for stage I endometrial cancer patients has again concluded that the treatment doesn't affect survival outcomes. But its findings, published in the Journal of the National Cancer Institute, sparked some controversy.
MRI helpful but not perfect for evaluating pancreatic cancer
December 27, 2012 -- Understanding how contrast-enhanced MRI underestimates tumor size compared to pathologic specimens may allow more precise assessment of tumor volume prior to radiation therapy for pancreatic cancer, according to researchers from Emory University.
FDG-PET/CT shines in assessing distant cancers
December 21, 2012 -- Whole-body FDG-PET/CT offers "excellent diagnostic performance" in the assessment of distant malignancies in patients with head and neck, breast, and lung cancers, according to a new study in the Journal of Nuclear Medicine.
Report: U.S. therapeutic radiopharma market set for growth
December 20, 2012 -- Fueled by new radiopharmaceuticals to treat various forms of cancer, U.S. sales of therapeutic radiopharmaceuticals over the next several years could reach $5.8 billion by 2020, according to a new market research report from Bio-Tech Systems.
