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.

Thursday, May 28, 2026, 1:00–2:00 PM ET
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.

Abstracts

Clinical Pathology Selected Abstracts

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.

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.

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.

April 2020—An outbreak of pneumonia occurred in Wuhan, Hubei province, China, in December 2019. A novel coronavirus was identified as the causative agent and named SARS-CoV-2 by the World Health Organization (WHO). The disease, COVID-19, is considered a relative of severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS). SARS-CoV-2–infected patients presented with a dry cough, dyspnea, fever, and bilateral lung infiltrates.

April 2020—Lymphocytic esophagitis is a well-known manifestation of Crohn disease among children but is not considered an immune-mediated mucositis in adults. The authors conducted a study for which they hypothesized that adult-onset lymphocyte-predominant esophagitis is also an immune-mediated inflammatory pattern, the nature of which has been masked by other conditions that feature esophageal lymphocytosis and occur in older adults. The intent of the study was to consolidate diagnostic criteria for lymphocyte-predominant esophagitis and determine its clinical significance.

April 2020—Prior to the recent novel coronavirus outbreak, the vast majority of coronaviruses that were known to be pathogenic in humans caused mild symptoms, with the exception of two strains. These included SARS (severe acute respiratory syndrome coronavirus [SARS-CoV]) and MERS (Middle East respiratory syndrome coronavirus [MERS-CoV]). SARS was documented as having emerged in the Guangdong province in southern China in 2002 and having caused at least 774 reported fatalities worldwide, while MERS, which was first detected in Saudi Arabia in 2012, was responsible for at least 858 fatalities worldwide.

Clinical Pathology Selected Abstracts

March 2020—U.S. guidelines for human papillomavirus vaccination are 11 to 12 years, with a catch-up vaccination up to age 26 for women and 21 for men. The FDA recently expanded the approved age for HPV vaccination in adult women and men from nine through 45 years. The changes are based on safety data and efficacy as well as potential incremental population-level health benefits. The authors conducted a study to evaluate the added population-level effectiveness and cost-effectiveness of extending the current U.S. HPV vaccination program to women ages 27 through 45 years and men ages 22 through 45 years. They used HPV-ADVISE (agent-based dynamic model for vaccination and screening evaluation), a model for HPV infection and associated diseases specific to U.S. data.

Molecular Pathology Selected Abstracts

March 2020—Microsatellite instability status in solid tumors is a critical biomarker for predicting tumor response to an immune checkpoint inhibitor drug. The immune system is more likely to attack those tumors that have a high degree of microsatellite instability, a consequence of the genomic instability that also leads to generation of the neoantigens the immune system is designed to recognize.

Anatomic Pathology Abstracts

March 2020—Conflicting data about the clinical significance of microscopic Crohn disease activity at resection margins have led to varying practice patterns for routine reporting by pathologists. The authors performed a multicenter retrospective cohort study of 101 consecutive Crohn disease bowel resections during a 10-year period to characterize the association between active disease at resection margins and postoperative Crohn disease recurrence and time to recurrence. Margin slides were reviewed, and Crohn disease activity at the margins was graded as none, mild, moderate, or severe. The authors used logistic regression and Cox regression analyses, respectively, to evaluate the association between microscopic Crohn disease activity at the margins and postoperative recurrence and time to recurrence.

Blood utilization and transfusion reactions in pediatric patients transfused with platelets

February 2020—Even with advances in donor screening and infectious disease testing, the risk of transfusion-transmitted infections continues to be a concern. The FDA has approved a pathogen-reduction system for single-donor platelets, called Intercept Blood System (Cerus Corp.), to treat thrombocytopenic adult and pediatric patients.
