Oncology Imaging

 

Five years ago the American Society of Clinical Oncology (ASCO) advised clinicians not to order advanced imaging or tumor marker tests for survivors of early-stage breast cancer. Yet the exam orders keep coming.

Reviewing brain MRI of close to 4,000 children as part of an ongoing population-based study, European neuroradiologists and neuroscientists discovered at least one incidental finding in more than one-quarter of the cohort.

The National Academy of Medicine announced Monday, Oct. 17, that it elected 80 new members, including Deborah Watkins Bruner, RN, PhD, a professor of radiation oncology at Emory University in Atlanta. 

A single 90-minute examination designed to assess chemotherapy-induced injuries of the brain, heart and joints among childhood cancer survivors has been proven feasible by a new study.

Starting annual screening mammography for breast cancer at age 40 helps detect a significant number of cancers, according to a recent study published in the American Journal of Roentgenology.

ASTRO: Many lung cancers stand little chance against stereotactic body radiation therapy—and conventional radiotherapy’s days are numbered too

BOSTON—Stereotactic body radiation therapy (SBRC) has beaten the pants off conventional radiation therapy in the Veterans Health Administration, significantly boosting both overall and lung cancer-specific survival in thousands of patients with stage I non-small cell lung cancer (NSCLC) in the first decade of the 21st century. 

ASTRO: Targeted radiation cuts local recurrence of brain metastases, but other outcomes measures not as impressive

BOSTON—If given the chance to choose between two recurrence-busting radiotherapy methods, many patients who have had a metastatic tumor resected from their brain would likely choose finely targeted stereotactic radiosurgery (SRS) applied only to the surgical bed of the resected lesion over radiation therapy applied to the entire brain. 

ASTRO president outlines plan for greater patient safety, more ‘moonshot’ involvement

Helping radiation oncologists learn from their own medical errors, adopt standardized best practices and participate more prominently in the Obama administration’s “cancer moonshot”: Those three areas of activity currently top the priority list of the American Society for Radiation Oncology (ASTRO). 

MRI bests ultrasound for cancer screening of cirrhotic livers, but is it fiscally feasible?

When surveilling cirrhosis-stricken patients for hepatocellular carcinoma—or HCC, the frequently incurable cancer that starts in the liver and sometimes follows cirrhosis—MRI with liver-specific contrast can be a better diagnostic performer than ultrasound, the guideline-recommended screening tool for such situations. 

Cancer-detection software proves a worthy, albeit imperfect, ‘second reader’ of lung CT

Computer-aided detection (CAD) may be useful as a “second reader” of low-dose CT lung images, as four CAD systems in a small study found up to 70 percent of lung cancers a radiologist had missed yet missed around 20 percent of cancers that human eyes had caught.

Oncologic neurorads giving second-opinion reads hit 100 percent correct rate

Second-opinion interpretations of neuroimaging studies by subspecialized oncologic neuroradiologists can significantly cut error rates and, in the process, improve cancer care, according to the authors of a study published in the Sept. 1 issue of the biweekly journal Cancer.

‘Inevitable’ ioMRI increases brain-tumor procedure times

Intraoperative MRI (ioMRI) soon may be must-have technology for many if not most neurosurgical suites, but those looking to take the plunge for their brain-tumor service line should expect longer procedure times and more scrupulous pre-operative room preparation.

Multiple prior gadolinium doses may remain in numerous brain sections

Gadolinium-based contrast agents (GBCAs) have shown up as bright signals, or “hyperintensities,” in T1-weighted MR brain images of patients with no such contrast administered at present but 35 or more linear GBCA doses in the past. 

Study finds obesity more prevalent in those with history of cancer

New research from Columbia University shows that patients who’ve suffered from cancer may have a harder time warding off extra pounds, and it may be even more difficult for patients of color.

MRI and CT have contributed much to brain tumor care over the years

The prognosis for patients with meningiomas, the most common tumors of the brain and spinal cord, has improved in the decades since advanced imaging began aiding detection.
