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

Moderated by: Bob McGonnagle, Publisher, CAP TODAY

Hear an expert discuss the expanded clinical utility of HER2 IHC scoring in metastatic breast cancer and its impact on your practice

Webinar presenter Michelle Shiller, DO, AP, CP, MGP, FACP, Baylor University Medical Center.

Wednesday, July 15, 2026, 1:00-2:00 PM ET
Hear an expert discuss how to integrate Kappa and Lambda in situ hybridization testing into your standard hematopathology workflow to accurately assess B-cell and plasma cell clonality. You will also gain the skills to recognize testing pitfalls in challenging reactive versus neoplastic proliferations and apply ancillary tools to resolve complex cases.

Clinical pathology selected abstracts

March 2024—Despite research into colorectal cancer screening and clinical experience, screening uptake remains low. Colorectal cancer (CRC) screening involves noninvasive tests, such as a fecal immunochemical test (FIT) and stool-based DNA tests, as well as invasive tests, such as colonoscopy. The latter has the best performance characteristics for early cancer and adenoma detection. The average adherence to CRC screening is 60.6 percent for U.S. patients aged 50 to 75 years, which is well below the 80 percent goal for adherence set by the National Colorectal Cancer Roundtable and American Cancer Society. Offering stool-based tests to patients who refuse colonoscopy results in only a modest increase in adherence, to 67 percent.

Anatomic pathology selected abstracts

March 2024—Lung transplantation is the definitive therapy for end-stage pulmonary sarcoidosis. While several case reports have described recurrent sarcoidosis in allografts, the incidence and clinicopathologic characteristics remain unclear. The authors conducted a study in which they characterized the clinical and histopathologic features of recurrent sarcoidosis diagnosed in post-transplant lung surveillance transbronchial biopsies (TBBx). They identified 35 patients who underwent lung transplant for pulmonary sarcoidosis during the study period. Eighteen (51 percent) of the patients experienced recurrent sarcoidosis post-transplant—seven females and 11 males (mean age at recurrence, 51.6 years).

Molecular pathology selected abstracts

March 2024—Human epidermal growth factor receptor 2 is a critical biomarker in breast cancer, gastrointestinal malignancies, and other cancers. HER2 protein expression can be evaluated using IHC, and the DNA copy number of its encoding gene, ERBB2, can be evaluated using FISH. In most clinical settings, IHC evaluation is categorized as positive (3+), equivocal (2+), or negative (0 to 1+), with equivocal cases being reflexed to FISH. Patients with HER2-positive tumors, defined as either 3+ or 2+/FISH positive, have been eligible to receive HER2-targeted therapy for many years. More recently, the FDA approved the antibody-drug conjugate trastuzumab deruxtecan (T-DXd) to treat patients with HER2-low breast cancer, defined as tumors with IHC 1+ or 2+/FISH negative. This promising treatment has allowed many more patients to receive molecular-targeted therapy.

Q. Is it a requirement that routine bacteriology cultures (for example, urine, sputum) be plated in a biological safety cabinet in your typical hospital biosafety level 2 laboratory? Is it safe to read these cultures on an open bench? Read answer.

Q. What source should a laboratory use for reference intervals for analytes? Read answer.

March 2024—While Dr. Seuss’ assertion that “the more that you read, the more things you will know” is generally accurate, it doesn’t address the fact that how information is presented affects comprehension, a truism that is not lost on Edward Klatt, MD, who knows whereof he speaks when it comes to sharing information on patient portals.

Put It on the Board

March 2024—The Food and Drug Administration approved in December the AvertD test, which assesses whether an individual may have an elevated risk of developing opioid use disorder. Its intended use is to inform the decision-making of patients and physicians about the use of oral opioids for acute pain relief.

Doing more, doing better in bladder cancer

February 2024—From her vantage at the University of Texas MD Anderson Cancer Center, Donna Hansel, MD, PhD, has a clear view of cancer’s latest frontiers. Progress and breakthroughs are the norm. But even she sounds impressed when she surveys the changes in her specialty, urothelial cancer. “We are now thinking what we never before thought was possible: We are thinking about cures and lifelong remission from disease,” says Dr. Hansel, division head and professor of pathology and laboratory medicine. It’s been a long time coming, says Dr. Hansel, who is also the Dr. Eva Lotzova and Peter Lotz memorial research chair. The disease historically has been caught in a sort of prepositional triangle—underfunded, overlooked, and underdiagnosed—with serious consequences. For years, she says, “We thought bladder cancer had only one treatment”—BCG, or Bacillus Calmette-Guérin, therapy. Because the field lacked a large volume of research to propel better diagnostics and treatments, “people died of this disease because it progressed.”

As AI use expands, ethics at the leading edge

February 2024—Artificial intelligence is sizzling, so much so that New Yorker magazine, evoking the dazzling and the potentially devouring nature of AI technology, tagged 2023 as “The Year A.I. Ate the Internet.”

Biomarker tests with discrepant results—why the differences?

February 2024—When multimodality testing reveals discordant biomarker results, which method is correct? Annette S. Kim, MD, PhD, and JinJuan Yao, MD, PhD, in a CAP23 session last fall used their cases to share strategies for resolving discrepancies—or, in some cases, what look like discrepancies.

With pipeline for pathologists, others lacking, eyes on AI

February 2024—Artificial intelligence and Medicare Advantage contracts were at the center of the Jan. 2 Compass Group virtual roundtable led by CAP TODAY publisher Bob McGonnagle. “If you want to get into the AI world, there are many lanes you can swim in,” said Michael Feldman, MD, PhD, of Indiana University School of Medicine.
