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 Center, and Colin Murphy, CEO of mTuitive.
Moderated by: Bob McGonnagle, Publisher, CAP TODAY

In this webinar, we will examine how immune recognition after allogeneic HCT can influence leukemia relapse and disease progression. The session will highlight the clinical relevance of HLA loss of heterozygosity (LOH), approaches used for its detection, and how LOH findings may support transplant strategies, including considerations for donor selection in subsequent transplantation.
Webinar presenter Alberto Cardoso Martins Lima, PhD, Clinical consulting scientist in histocompatibility,
specializing in allogeneic hematopoietic cell transplantation (HCT) at IGEN/AFIP São Paulo and CHC/UFPR in Curitiba, Brazil

Big interest, gaps in early pancancer testing
August 2025—There’s the cart before the horse. There are certain equines that should not be flogged; others should not be backed. There’s closing the stable door at an unfortunate time.
Too few phlebotomists—is Aletta the answer?
July 2025—It was one of those infamous winter days in Chicago. The phlebotomy staff were calling off work, and Gregory S. Retzinger, MD, PhD, had reached his breaking point. Phlebotomists tend to be in short supply, and Northwestern Memorial Hospital, where Dr. Retzinger is medical director of pathology clinical services, is no exception.
Tumor marker testing in body fluids calls for caution
June 2025—With few FDA-cleared or -approved methods for tumor marker testing in body fluids, it is the laboratory that’s responsible for the tests. “A specimen arrives at your door, and you have to figure out what, if anything, you’re going to do,” said Jonathan Genzen, MD, PhD, MBA.
Taking on low, ultralow HER2 breast cancer
May 2025—Since the hunt began to identify low levels of HER2 in metastatic breast cancers, the action has revealed itself like the plot of a Henry James novel: Nothing much happens. Also, a lot happens. And each narrative thread is conveyed in hard-to-parse language. The goal has been to qualify patients for the antibody-drug conjugate trastuzumab deruxtecan (T-DXd), which was shown in the Destiny-Breast04 trial to significantly improve survival in so-called HER2-low cases. Immunohistochemistry assays were designed to identify strongly positive cases, however, and thus not useful for those at the 0 and 1+ end of the spectrum. Now, several years after the presentation of the D-B04 results at the ASCO 2022 annual meeting, which launched the low-end ship, pathologists and oncologists are adjusting to the implications of the most recent Destiny trial, D-B06. In late January, the FDA approved the drug Enhertu for HER2-low or HER2-ultralow cases, as well as the Ventana Pathway HER2 (4B5) companion diagnostic for assessing these lower levels of HER2 in patients with metastatic breast cancer.
For myeloid malignancies, how WHO-HEM5 and ICC differ
May 2025—How the World Health Organization fifth edition of hematolymphoid tumors and the International Consensus Classification differ for myeloid malignancies was highlighted in cases presented in a CAP24 session last fall. Sanam Loghavi, MD, associate professor of pathology and laboratory medicine, Department of Hematopathology, University of Texas MD Anderson Cancer Center, spoke of myelodysplastic neoplasms/syndromes (MDS) with defining genetic abnormalities and the allelic state of TP53 in MDS, among other things. (Kamran M. Mirza, MD, PhD, of the University of Michigan, co-presented.)
Not to be overlooked: lab administrative skill
April 2025—The transition from pathology training to practice is not just about diagnostic skill and confidence in that skill but also laboratory administrative duties, with experience in the latter harder to gain as a trainee.
