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 2D 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.

“Integration of a scoring system into structured prostate MRI reports could be of great value to clinical research as well as routine clinical care...," wrote authors of a new study published in the American Journal of Roentgenology, which examined how background signal-intensity changes affect prostate cancer detection.

“In this study, for patients with stage-IV disease, we have a treatment paradigm that can result in long-term survival while maintaining overall quality of life,” said senior author of the study, Dwight E. Heron, MD.

A new three-dimensional (3D) imaging technique to analyze tissue samples allowed scientists to determine that pancreatic cancers can start and grow in two distinct ways, according to a Jan. 30 study published in Nature. The findings solve a question that’s plagued researchers for decades.
