Scientists Use Thousands of Genetic Markers to Develop Risk Scores for Six Common Diseases: Findings May Have Implications for Clinical Laboratories

Study demonstrates how precision medicine is advancing because of new insights from the use and interpretation of whole-genome sequencing As part of the Genomic Medicine at Veterans Affairs Study (GenoVA), researchers from Harvard Medical School, Veterans Affairs Boston Healthcare System, and Brigham and Women’s Hospital in Massachusetts used thousands of genetic markers to develop and validate polygenic risk scores (PRS) for six common illnesses. These findings may eventually provide clinical...

University of Colorado Researchers Develop Miniature Colonoscopy Robot Capable of Collecting Biopsies and Transmit Diagnostic Information in Real Time

GI pathologists will be interested in how the Endoculus device uses tank-like treads to traverse the gastrointestinal tract, where it can capture images and perform biopsies Gastroenterologists (GI) may soon gain a useful new tool for use in gathering both biopsies and diagnostic information when examining the gastrointestinal tract. Ongoing development of a new robotic device promises both capabilities using technology that will be of interest to GI pathologists and clinical laboratory...

AdventHealth Gives 10,000 Floridians Free Genetic Tests, Sees Genomics as the Future of Precision Medicine

Many other healthcare systems also are partnering with private genetic testing companies to pursue research that drive precision medicine goals It is certainly unusual when a major health network announces that it will give away free genetic tests to 10,000 of its patients as a way to lay the foundation to expand clinical services involving precision medicine. However, pathologists and clinical laboratory managers should consider this free genetic testing program to be the latest marketplace...

Regenstrief Institute Finds Fecal Immunochemical Test May Be as Effective as Colonoscopy at Detecting Colorectal Cancers

Doctors may begin ordering FITs in greater numbers, increasing the demand on clinical laboratories to process these home tests All clinical laboratory managers and pathologists know that timely screening for colon cancer is an effective way to detect cancer early, when it is easiest to treat. But, invasive diagnostic approaches such as colonoscopies are not popular with consumers. Now comes news of a large-scale study that indicates the non-invasive fecal immunochemical test (FIT) can be as...

Researchers Discover Link between Gut Bacteria and the Effectiveness of Certain Cancer Drugs; Knowledge May Lead to New Types of Clinical Laboratory Tests

Microbiome is once again leading scientists toward a new understanding of how human gut bacteria can impact the efficacy and side-effects of certain cancer therapies Anatomic pathology researchers already know that a person’s genetics can affect the results of cancer treatments. Now it is becoming clear that a patient’s microbiome—which includes gut bacteria—may also impact the efficacy of particular cancer treatments. A recent study showed that gut bacteria can be used to determine whether a...
