Researchers at The University of Kansas Cancer Center have launched a clinical trial that eliminates radiation from the treatment protocol for an invasive type of breast cancer that accounts for one-fifth of all breast cancer patients.

A large Norwegian study using automated breast density measurements found that women with mammographically dense breast tissue have higher recall and biopsy rates, and increased odds of screen-detected and interval breast cancer. The study, published online in the journal Radiology, supports automated measurements as a future standard to ensure objective breast density classification for breast cancer screening, the researchers said.

In the battle against metastatic castrate-resistant prostate cancer, studies have demonstrated a high response rate to radionuclide therapy targeting prostate specific membrane antigen (PSMA) with the radionuclide lutetium-177 (177Lu). At the 2018 Annual Meeting of the Society of Nuclear Medicine and Molecular Imaging (SNMMI), researchers reported on a phase II prospective trial. Using gallium-68 positron emission tomography (PET) imaging, men who had exhausted conventional therapies were screened. Those with high PSMA-expression proceeded to 177Lu-PSMA617 (LuPSMA) therapy and experienced high response rates, which is clearly demonstrated in the PSMA PET imaging figure selected as the 2018 SNMMI Image of the Year.

Embolx Inc. has received 510(k) clearance from the U.S. Food and Drug Administration (FDA) for its next-generation family of Sniper Balloon Occlusion Microcatheters for pressure-directed arterial embolization therapy. Now commercially available in the United States, the next-generation family of Sniper devices offers physicians enhanced performance features to improve access and allow easy navigation through small complex vascular structures.

A team of biologists has joined up with civil engineers to create what is believed to be the first 3-D computer model to show precisely how the tiny tubes that funnel milk through the breasts of mammals form. Understanding how such ducts form, the team says, may lend insight into how diseases such as metastatic breast cancers spread throughout the body. A report on the model was published April 9 in Developmental Cell.

At the 2018 Society of Nuclear Medicine and Molecular Imaging (SNMMI) annual meeting, June 23-26, in Philadelphia, MILabs introduced the new VECTor6 positron emission tomography (PET) system loaded with innovative features. New features incorporated in its 4x4D omni-tomography design include PET, single photon emission computed tomography (SPECT), optical and X-ray computed tomography (CT) imaging modalities.
