The PET radiotracer 68Ga-PSMA-11 improved the detection of biochemically recurrent prostate cancer, according to results of a prospective trial published in JAMA Oncology.

International researchers have created a new ultrasound probe capable of delivering more precise treatment to women with gynecological cancers, reported authors of a feasibility study published in the Journal of Medical Imaging.

The American College of Physicians (ACP) now recommends women undergo mammography ever other year, beginning at age 50. The new guidelines have drawn criticism from the American College of Radiology and Society of Breast Imaging.

In women 65 and older, digital breast tomosynthesis (DBT) achieved a higher specificity for detecting breast cancer and identified the disease at an earlier stage compared to traditional 2-D mammography.

Whole-body PET/CT with the standard radiotracer 18F-FDG is a dependable screening tool for catching many metastases, distant as well as regional lymphatic, according to researchers at the University of Minnesota.

MIT researchers have developed a near-infrared imaging technique that can detect tumors deep in internal tissue before the cancer grows beyond a few hundred cells.

Patients diagnosed with colorectal cancer prior to turning 50 were often misdiagnosed, which may result in a diagnosis at more advanced stages of the disease, according to the American Association for Cancer Research (AACR).  

DBT also identified more cancers and lowered recall rates in patients of all ages and breast density types.

"The takeaway here is that screening does matter, and the expansion of Medicaid has increased usage of colon cancer screening for many Kentuckians who otherwise wouldn't have had access," wrote authors of a Feb. 22 study published in the Journal of the American College of Surgeons.

Stereotactic ablative body radiation therapy (SABR) nearly doubled the overall survival of patients with inoperable stage I lung cancer compared to standard radiotherapy, according to results of a multi-center phase III trial published in the Lancet Oncology.

Breast cancer screening centers may want to consider implementing digital breast tomosynthesis (DBT) and digital mammography (DM) into their practice, according to results of a recent Radiology study. Pairing both modalities significantly increased the sensitivity and specificity of detecting breast cancers.

Traditionally, men with low-risk prostate cancer had undergone radical prostatectomy or radiation, but many are now opting for a more conservative active surveillance approach, according to a Feb. 11 analysis published in JAMA.
