Thursday, April 30, 2026, 11:00 AM–12:00 PM ET
Hear an expert discuss how Memorial Sloan Kettering Cancer Center (MSKCC) is utilizing
the oncoReveal® Nexus 21-gene panel to redefine turnaround time and actionable insights
in cancer care. Dr. Ewalt shares a perceptive look at the clinical need for rapid, front-line NGS sequencing, and how a unique, purpose built targeted NGS panel (Pillar Biosciences’ oncoReveal Nexus 21 gene Panel) was developed, validated and implemented clinically by Memorial Sloan Kettering Cancer Center (MSK-REACT) to complement their current comprehensive genomic profiling (CGP) approach.

Webinar presenter Mark Ewalt, MD, Associate Medical Director for Laboratory Operations for Diagnostic Molecular Pathology in the Molecular Diagnostics Service, Department of Pathology and Laboratory Medicine, MSKCC.

This session is designed to improve understanding and application of recent updates to synoptic pathology reporting protocols such as the latest Reporting Template for Reporting Results of Biomarker Testing of Specimens from Patients with Carcinoma of the Breast. These changes reflect evolving clinical guidelines that directly influence diagnostic accuracy and treatment selection in breast cancer care.

Webinar presenters Thaer Khoury, MD, FCAP, Chair, Pathology and Laboratory Medicine, Roswell Park Comprehensive Cancer Cente, and Colin Murphy,  CEO of mTuitive.

May 2020—Imagine the potential educational benefits of pathology residents being able to see the precise path that the eyes of experienced pathologists take as they scan a whole slide image. Preliminary research has suggested that showing residents visual representations of a pathologist’s eye-tracking movement overlaid over a whole slide image can impact how they learn, says Sharon E. Fox, MD, PhD, a pathologist at the Southeast Louisiana Veterans Healthcare System and associate director of research and development, Department of Pathology, Louisiana State University Health Sciences Center.

May 2020—Laboratory costs represent approximately three to four percent of overall health care expenses but drive 70 to 80 percent of decisions made by physicians. One way to control laboratory testing expenditures is through appropriate utilization. For example, thyroid and antinuclear antibody (ANA) testing have reliable initial screening tests, yet specialized testing is overutilized for both. In 2000 guidelines, the College of American Pathologists and American College of Rheumatology established that the ANA screen by immunofluorescence in the setting of a negative result is sufficiently sensitive not to perform further testing with subserologies and that thyroid-stimulating hormone (TSH) is a sensitive marker of thyroid function and can often be used without further testing with a normal TSH.

Anatomic Pathology Selected Abstracts

May 2020—Flat epithelial atypia is an alteration of terminal duct lobular units by a proliferation of ductal epithelium with low-grade atypia. No consensus exists regarding whether the diagnosis of flat epithelial atypia in core needle biopsy necessitates excision. The authors retrospectively identified all in-house core needle biopsies with flat epithelial atypia obtained at their institution between January 2012 and July 2018. They reviewed all core needle biopsy slides and assessed radiologic-pathologic concordance. An upgrade was defined as invasive carcinoma or ductal carcinoma in situ in the excision, or both. The excision slides of all upgraded cases were re-reviewed.

Molecular Pathology Selected Abstracts

May 2020—Each year a growing number of novel viruses are discovered in the wild animal kingdom with the use of next-generation sequencing technology. However, the current method of functionally assessing the zoonotic potential—that is, the potential to be transmitted to humans—of novel viruses involves synthesis of viral genomes (tens of thousands of bases) and reverse genetic engineering to produce a recombinant virus. This is expensive and time-consuming, and it is not practical due to the scale of new viral strains being discovered. To overcome this hurdle, Letko, et al., developed a rapid and cost-effective method that could functionally assess a number of related viruses for zoonotic potential. The essential component of viral cross-species transmission is cell entry, which is a multi-step process involving attachment of the virus to the host cell surface, receptor engagement, processing of host proteases, and downstream membrane fusion.

AST breakpoints: a case of not aging gracefully

April 2020—When Romney Humphries, PhD, D(ABMM), was section chief for clinical microbiology at UCLA Medical Center, it wasn’t unusual for her to take calls from worried clinicians who were concerned about patients who’d been transferred to the hospital for a higher level of care. The accompanying laboratory reports would indicate the presence of an isolate that was susceptible to a particular drug. But when Dr. Humphries’ lab did its own testing, the results were strikingly different: The isolate was drug resistant. When Dr. Humphries would call the first lab, the reason for the discrepancy became clear. “Sure enough, they were using old breakpoints,” says Dr. Humphries, who is now chief scientific officer, Accelerate Diagnostics, and professor of pathology, University of Arizona. Unlike Bordeaux, antimicrobial susceptibility test breakpoints do not age well. Over time, they might no longer be clinically useful, even as they continue to be used clinically. Dr. Humphries’ anecdote is, of course, just that—an anecdote.

Transfusion cases out of cabinet, into new book

April 2020—CAP Publications released this month a new book titled Transfusion Medicine: A Compendium of Educational Cases, from the CAP Transfusion, Apheresis, and Cellular Therapy Committee. In it are 20 cases, each with a history, discussion, and questions and answers. Read more.

Billing practices, problems — we ask the experts

April 2020—Billing and collecting for pathology and laboratory services is “tough and getting tougher.” That’s the view of consultant Al Sirmon of Pathology Practice Advisors, Pawleys Island, SC. “In what other industry,” he asks, “do you rely on a third party to decide how much and when you’re going to get paid for a service you provide to someone else?” On the bright side, he says: “We have better tools now.”
