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.

Many smokers with elevated cancer risk don’t adhere to follow-up imaging recommendations

Just over half of current smokers who receive an abnormal chest CT exam adhere to radiologists’ recommendations for follow-up imaging within 30 days, according to results of a study published online Feb. 28 in the Journal of the American College of Radiology

Women with early breast cancer getting unnecessarily imaged in Michigan

The Great Lakes State is seeing rampant inconsistency statewide in the utilization of staging scans when women are diagnosed with early-stage breast cancer, and much of the variability owes to imaging orders that buck national guidelines.

Chemo better than chemoradiation for adjuvant treatment of pancreatic cancer

The first multicenter study analyzing recurrence patterns following post-surgery treatments for pancreatic cancer has shown that adjuvant chemotherapy is a good way to go, as it thwarts both local and distant recurrence. By comparison, adjuvent chemoradiation beats back local recurrence but not metastasis, which translates to less impact on overall survival.

Interrupted radiation-therapy regimens more compromised than previously thought

A new study reinforces the expectation that cancer patients who postpone radiation therapy treatments will have poorer outcomes than those who fully comply with the program as scheduled. No surprise there, but the researchers also found that the differences are sharp, consistent across disease sites and observable despite eventual program completion by the stragglers.

Clearer targets for brain tumor-busting drugs may emerge from new ‘toolkit’

German researchers have developed a way to combine MRI with ultramicroscopy to study the growth of blood vessels in glioma mouse models, and in exacting detail. Their new “toolkit” may aid future efforts to target particular vessels in brain tumors for glioblastoma therapies.

Doctor, lawyer upbraid Congress for ‘undermining science’ on mammo screening

Hot on the heels of final-draft guidelines from the U.S. Preventive Services Task Force (USPSTF) on screening mammography comes blistering commentary from two Georgetown University professors—one a physician and the other an attorney—taking Congress to task for the way it has acted to implement the recommendations.

Minority subgroup gets far less cancer but has much worse outcomes

Nothing kills more AANHPIs—that’s the population subset comprising Asian-Americans, Native Hawaiians and Pacific Islanders—than cancer. Yet AANHPIs have whopping 30 percent to 40 percent lower incidence and mortality rates than non-Hispanic whites for all cancers combined. 

Rads urged to overcome ‘stage fright’ when interpreting cancer images

Radiologists have a key role to play in cancer staging, but many seem to need a nudge to get on with it. 

Stats show cancer on the run—but the fight far from finished

The American Cancer Society is out with its annual rundown of cancer statistics, and overall the news is encouraging.

Researchers to test 4D CT’s potential for guiding tissue-sparing radiation therapy

A proposed clinical trial exploring the ability of 4D CT to identify healthy lung tissue that can be spared during cancer radiotherapy has received NIH funding.
