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.

From the President’s Desk—CAP accreditation: perspective-taking 101
October 2018—I grew up in the CAP as a volunteer in the Laboratory Accreditation Program. It’s a good place to dive in. Many of us do what I did—work our way through many volunteer opportunities over 30 years or more because each was so interesting. There are an amazing number of ways a person can approach challenges in a laboratory; more amazing is how many of the approaches will work. Partly that’s because the learning cuts both ways—I’ve learned as much when we were inspecting another laboratory as when my laboratory was being inspected.

RT-PCR detection of B. microti parasites using BMN antigens as amplification targets
October 2018—Babesia microti infection, which is transmitted through the bite of an infected tick, is a growing health concern and continues to be a threat to the blood supply, with 22 states having reported cases of babesiosis in 2014. While most healthy adults with Babesia infection are asymptomatic or present with mild symptoms, including fever, fatigue, and anemia, babesiosis can be severe or fatal in neonates, the elderly, and immunosuppressed individuals.

Analysis of ZC3H7B-BCOR high-grade endometrial stromal sarcomas
October 2018—High-grade endometrial stromal sarcoma likely encompasses underrecognized tumors harboring genetic abnormalities besides YWHAE–NUTM2 fusion. Triggered by three initial endometrial stromal sarcomas with ZC3H7B–BCOR fusion characterized by high-grade morphology and aggressive clinical behavior, the authors investigated the clinicopathologic features of this genetic subset by expanding the analysis to 17 such tumors. All of the tumors occurred in women who were a median age of 54 (range, 28–71) years.

Cell-free DNA tumor mutational burden predicts efficacy of immune checkpoint inhibitors
October 2018—Immune checkpoint inhibitors have emerged as a potent class of therapy for a variety of malignancies. The biologic rationale for these drugs is that somatic mutations, not necessarily in cancer driver genes, may accumulate in tumor cells, resulting in amino acid changes that create neoantigens (epitopes not present in normal cells during maturation of the immune system).

AMH immunoassays
October 2018—In the article “Satisfaction high with new automated AMH assays” (June 2018), the focus seems to be on the presumed advantages of the Roche Elecsys and Beckman Coulter Access automated anti-müllerian hormone assays over manual AMH assays. The article reports that the main advantages of the automated platforms are less variability in AMH measurements, greater assay turnaround time, and greater assay cost-effectiveness.
