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.

ARTICLES

A practical approach to borderline melanocytic neoplasms

August 2022—In cases of borderline melanocytic neoplasms, which have overlapping histopathologic features of benign and melanocytic lesions, additional immunohistochemical studies sometimes help to differentiate the two. But a subset of lesions will show overlapping features.

Looking for lab staff here, there, and overseas

August 2022—Higher wages help to fill open positions, when they can be offered, but in a labor market that’s as tight as ever, they’re often just a start. That’s why many laboratories are casting wider nets, though the hiring solutions tend to be long term.

Infectious diseases of the gut

August 2022—The atypia in Epstein-Barr virus-positive mucocutaneous ulcers can mimic diffuse large B-cell lymphoma or classical Hodgkin lymphoma, a diagnostic pitfall that can result in overtreatment. And esophageal ulcers in immunocompromised patients should trigger cytomegalovirus immunohistochemistry in addition to GMS and herpes simplex virus-1 and -2 stains.

Close-up on HER2 alterations in advanced NSCLC

August 2022—HER2 is a known oncogenic driver and emerging biomarker in non-small cell lung cancer, and while the therapeutic implication is not yet fully known in NSCLC, “we need to pay attention to it,” said Fred R. Hirsch, MD, PhD, executive director of the Mount Sinai Center for Thoracic Oncology and associate director, Tisch Cancer Institute, in a CAP TODAY webinar sponsored by Daiichi-Sankyo and AstraZeneca.

Savings, schedules, new automation—labs weighing it all

August 2022—Running into the reality of staffing. Those are the words of a pathologist who said in the most recent Compass Group roundtable that its health system is making a push to obtain and test specimens “as close to home as possible.” Another Compass Group member said planning is underway for the new hospitals his system is going to build, “but we don’t know where staff will come from.” Here is what they and others told CAP TODAY publisher Bob McGonnagle on July 5.

Cytopathology in focus: Protocol for reporting cervicovaginal cytology specimens

August 2022—The protocol for the reporting of cervicovaginal cytology, the first in a series of CAP cytopathology protocols, became available for use in a synoptic format on June 22. This protocol is a collaborative effort, based on input from past and present members of the CAP Cytopathology Committee and prepared in conjunction with the CAP Pathology Electronic Reporting Committee. It was presented via webinar to the CAP House of Delegates on March 31. A two-week open comment period followed; all comments were reviewed and appropriate changes were incorporated into the protocol.

Cytopathology in focus: Advances in detection of mesothelioma in cytology pleural fluid specimens

August 2022—The ability to make a definitive diagnosis of mesothelioma on pleural fluid cytology has been questioned and debated for a long time. The 2018 American Society of Clinical Oncology clinical guidelines limit the cytological diagnosis of pleural fluid specimens only as an initial screening test for mesothelioma. Monaco, et al., discuss in their article the appropriate use of ancillary studies (immunohistochemistry and fluorescence in situ hybridization studies) to make a definitive diagnosis of mesothelioma in small tissue samples, which are often processed as cell blocks. The authors recommend a stepwise approach starting with immunohistochemistry for BAP1 and, next, MTAP in cases of atypical mesothelial proliferations where the suspicion for malignant mesothelioma is high.

Transgender care, in and beyond the lab

July 2022—Gabrielle Winston-McPherson, PhD, could be talking about almost any aspect of laboratory medicine as she recounts how the Henry Ford Health chemistry division, in which she is associate director, has identified a patient care need. She talks about the desire to improve health outcomes. Identifying problems in the preanalytical process. Appropriate test utilization. Putting together a team to develop training material. Assembling data and information prior to implementation. Informatics challenges. And, naturally, the perpetual financial concern of ensuring allocation of limited resources. How else would she—or any other laboratory professional—talk about the lab’s role in transgender health care? In fact, there are many other ways to discuss the topic. “It’s been in the news a lot these days, obviously,” says Matthew Krasowski, MD, PhD, clinical professor and vice chair, clinical pathology and laboratory services, University of Iowa Hospital and Clinics. In fact, there are many other ways to discuss the topic.

Monoclonal gammopathies: which tests and why

July 2022—Variability in testing for monoclonal immunoglobulin proteins was in part what led to the new guideline on laboratory detection and initial diagnosis of monoclonal gammopathies, published in May.

Histology lab tips for top-tier whole slide images

July 2022—Good slides in, good images out. Liron Pantanowitz, MD, MHA, explained how to get those good images in a recent webinar on preanalytics quality control in digital pathology, sponsored by Sunquest and made available by the Association for Pathology Informatics.
