Zika virus has had a significant impact in North and South America, most notably by causing microcephaly in babies born to infected mothers. But Brazilian researchers have found the deadly virus may be an effective treatment for glioblastoma—the most common and aggressive form of malignant brain tumor in adults.

In patients with early-stage breast cancer, neoadjuvant chemotherapy (NAC) is a common treatment to reduce tumor size before surgery. A team has found dynamic diffuse optical tomography (DDOT) can detect if a tumor has responded to chemotherapy within two weeks of initial treatment—potentially life-saving information for patients. ​​​​​​​

Pairing ultrasound with a blood test to detect high alpha fetoprotein (AFP) levels demonstrated up to a 40 percent improvement in detecting early-stage liver cancer, according to new research published in the journal Gastroenterology.

Pennsylvania researchers discovered opposed-phase MRI imaging is less accurate in detecting treated spinal metastases compared to those lesions that are untreated.

Nuclear imaging may better locate recurrent prostate cancer after prostatectomy and aid in earlier detection after recurrence all while simultaneously providing the sensitive imaging needed to guide salvage radiotherapy in patients, according to a study in the February issue of The Journal of Nuclear Medicine.

Oxygen-filled microbubbles increase breast cancer sensitivity to radiation

Breast cancer is the most common form of cancer among women. And a new study finds injecting oxygen-filled microbubbles into breast cancer makes tumors three times more responsive to radiation treatment, according to an International Journal of Radiation Oncology study.

JAMA study asks: Do we need to reexamine lung cancer screening?

High rates of incidental findings, limited risk-reward outcomes and unnecessary emotional stress suggest to one group of authors that lung cancer screening efforts need to be refined and the risk and benefits clearly communicated to better screen high-risk patients.

Researchers successfully block 'siren call' of aggressive cancers

Researchers from Georgia have successfully stifled the production of a chemical sent by aggressive cancers to bone marrow allowing them to thrive in the body.

ACR releases new appropriateness criteria promoting patient-centered care

New appropriateness criteria created to get patients more involved in their own care have been released today, online in the Journal of the American College of Radiology.

MRI technology lets patients skip biopsy

Researchers have developed a new MRI technology that allows patients with suspected kidney tumors to bypass biopsies. A recent study, led by Ivan Pedrosa, MD and Jeffrey Cadeddu, MD with the Kidney Cancer Program at the University of Texas Southwestern Harold C. Simmons Comprehensive Cancer Center, was published online Jan. 2 in The Journal of Urology.
