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.

Stage I lung cancer patients still getting needlessly imaged for brain metastases

A new study supports the Choosing Wisely position that neuroimaging does not give worthwhile benefit to patients with screening-detected stage I non-small-cell lung cancer (NSCLC) but no symptoms of metastasis to the brain. However, the same study shows that many patients are receiving the imaging anyway.

Doctors test active surveillance care model to prevent overtreatment of prostate cancer

Urologists from the University of California, Sand Diego School of Medicine have collaborated with Genesis Healthcare Partners to test a new model of care for managing low-risk prostate cancer patients, according to results of a study published in the journal Urology.

Reducing bladder tumor recurrence with narrow band imaging

Researchers from the University of Birmingham in the United Kingdom have found that utilization of narrow band imaging can substantially reduce the risk recurrence from bladder cancer, according to results of a new study published in European Urology.

Imaging-based surveillance of pancreatic cancer candidates deemed ‘remarkable and encouraging’

The use of MR and/or ultrasound imaging to systematically surveil individuals at high risk of developing pancreatic ductal adenocarcinoma (PDAC) due to their carrying of a mutation in the CDNK2A gene has proven worthwhile, as researchers in a European study were able to detect most PDACs at a resectable stage.

Treatment costs of CT-related cancers could reach $2.6 billion over 10 years

Despite the many benefits of CT imaging—early diagnosis, enhanced diagnostic accuracy, improved outcomes, etc.—a small number of cancers resulting from patient exposure to radiation from CT scans can have a big financial impact on treatment costs, according to results of a study recently presented at the annual meeting of the American Roentgen Ray Society.

PET/MRI bests other modalities in imaging liver metastases related to colorectal cancer

Combined PET/MRI outperforms multidetector CT and PET alone in evaluating colorectal cancer liver metastases (CRLMs), according to study results published online April 19 in the journal Radiology.

Ultrasound-driven microbubbles target cancer cells

Scientists from Nanyang Technological University in Singapore have developed a technique that uses tiny gas bubbles and ultrasound vibrations to deliver cancer drugs directly to cancer cells, effectively treating the tumor while sparing normal healthy cells.

Research review: Are nanoparticles safe for personalized cancer care?

One promising area of research into patient-specific cancer treatment strategies is the utilization of nanotechnology to treat and monitor the disease more effectively. But first, researchers need to be determine exactly how certain inorganic nanoparticles used in potential cancer treatments affect the body—both positively and negatively.

Q&A: What’s the secret to building a successful lung cancer screening team?

How do you take an assortment of individual medical professionals from various disciplines and turn them into a well-oiled lung cancer screening machine? Geoffrey Rubin, MD, details the challenges of building and managing a multidisciplinary team and the overall benefits of effective screening programs on the radiology profession.

Radiotherapy reduces pain from bone metastases but barely lifts quality of life

Radiation treatments help relieve pain from bone metastases, but the alleviation isn’t pronounced enough to improve patients’ overall quality of life, according to a Dutch study posted online March 29 in the International Journal of Radiation Oncology*Biology*Physics.
