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

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.

2025 Issues

Requirement changes in microbiology, transfusion checklists

February 2025—Some of the CAP accreditation program requirements in the 2024 microbiology and transfusion medicine checklists, in the edition released Dec. 26, have been revised to simplify, clarify, and conserve resources. In transfusion, one new requirement was added to define policy requirements for the use of low-titer group O whole blood.

Views on digital pathology, AI, and the AP LIS

February 2025—Digital pathology, artificial intelligence, and anatomic pathology computer systems—seven participants in a Dec. 10, 2024 online roundtable talked with CAP TODAY publisher Bob McGonnagle about their experiences, plans, and predictions. Large academic center practices and small pathology practices—they considered all perspectives. Here is what they told us.

From the President’s Desk

February 2025—Five years ago, many of us were grappling with the earliest cases of a novel coronavirus in the United States. During the COVID-19 pandemic that ensued, we pathologists became more visible in a variety of ways, both to our clinical colleagues and to the general public.

February 2025—Pulmonary complications cause significant morbidity and mortality in post-hematopoietic stem cell transplantation. The histopathology of pulmonary diseases in the context of post-hematopoietic stem cell transplantation (post-HSCT) is poorly characterized, especially in the pediatric population. The authors sought to characterize the pathologic spectrum of pulmonary disease post-HSCT in a pediatric cohort. Fifty-six specimens, including 53 biopsy specimens, corresponding to 53 patients were identified. Biopsy slides were reviewed and assigned to diagnostic categories (infectious, graft-versus-host disease, vasculopathy, indeterminate, and others) by consensus among three pediatric pulmonary pathologists, taking into consideration pathologic, clinical, radiologic, and laboratory findings.

Clinical pathology selected abstracts

February 2025—Low titer group O whole blood is commonly used for severe bleeding in trauma patients. It may also benefit pediatric patients undergoing cardiopulmonary bypass who are at risk for massive bleeding and coagulopathies. Circuit anticoagulation, hypothermia, hemodilution, coagulation factor, platelet loss and dysfunction, an underdeveloped hemostasis system in patients younger than two years old, and other factors lead to a higher risk of bleeding. Compared with component therapy, whole blood contains higher concentrations of RBCs, platelets, and coagulation factors, as well as cold platelets with enhanced hemostatic function. Due to the logistical challenges of donor centers providing ABO-specific whole blood for cardiopulmonary bypass (CPB), the use of longer storage-age low titer group O whole blood (LTOWB) may be an option for younger pediatric patients with severe bleeding on CPB.

Molecular pathology selected abstracts

February 2025—Excision repair cross-complementation group two (ERCC2) is a tumor-suppressor gene involved in DNA repair. Compound heterozygous mutations in ERCC2 are linked to rare recessive disorders, such as xeroderma pigmentosum, Cockayne syndrome, and trichothiodystrophy, all of which are characterized by ultraviolet light sensitivity. Somatic ERCC2 mutations in cancers, particularly bladder cancers, have emerged as significant prognostic markers. The mutations predict platinum sensitivity and correlate with favorable outcomes in patients with bladder cancer, but they have not been identified as independent prognostic indicators due to a lack of data, resulting from limited cohort sizes. The authors conducted a study in which they investigated the impact of ERCC2 hotspot mutations on genomewide mutagenesis and their implications for cancer prognosis and therapeutic stratification.

Q&A column

February 2025
Q. Is a pathology review on all cerebrospinal fluid (CSF) specimen differential slides necessary? Should the review be based on the number of white blood cells counted or the abnormality of the differential, or both? Read answer.

Q. At what level or time is aPTT considered incorrect? Is an aPTT of less than 22.0 seconds an acceptable result? Read answer.

February 2025—When NYU Langone Health began focusing on digital pathology last year, it also began focusing on people—those it would need to keep such a program humming along. “When we were setting up this operation, it was pretty obvious to me that I wanted to have a dedicated team of people that are going to focus just on digital pathology,” says Rui Soares, anatomic pathology operations director at NYU Langone, a multisite system with approximately 80 pathologists at four hospitals. It would be “unfair,” he adds, to expect laboratory assistants to learn and perform such specialized tasks while performing other duties.

February 2025—Roche’s whole slide imaging system, Roche Digital Pathology Dx, received an additional 510(k) clearance from the Food and Drug Administration. This latest clearance modifies the one Roche received in June 2024 for Roche Digital Pathology Dx, which includes the Ventana DP 200 slide scanner.
