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 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.

Building a lab or modernizing? Don’t forget the following
March 2019—Building a new pathology lab or revamping an existing one gives laboratory decision-makers an opportunity to rethink information technology infrastructure and address persistent problems, plan for new technology, and improve processes.
From the President’s Desk: Our study of member services and support
March 2019—We launched the CAP member services and support strategy two years ago, setting out to figure out which benefits were most valued by the greatest number of members, identify places where we could find better ways to direct or maintain them, and see where we could be falling short. To keep everyone connected and everything on track, we created a coordinating group whose members had access to a fine staff and thoughtfully curated findings from years of member surveys and market research. Our own surveys showed how the interests and needs of our members overlapped. The market provided context.

March 2019—Evaluation of ethanol interference on routine biochemical tests: Ethanol, a central nervous system depressant widely consumed in many societies, is metabolized in the liver through multiple enzymatic pathways. If the liver’s capacity is exceeded, the excess alcohol will flood into the systemic circulation.

March 2019—ALK expression in angiomatoid fibrous histiocytoma: a potential diagnostic pitfall:
The authors recently encountered a case of primary pulmonary angiomatoid fibrous histiocytoma (AFH), which was initially misdiagnosed as inflammatory myofibroblastic tumor based in part on anaplastic lymphoma kinase expression by IHC. Prompted by this experience, they evaluated anaplastic lymphoma kinase (ALK) expression in 11 AFH, 15 inflammatory myofibroblastic tumors (IMT), and 11 follicular dendritic cell sarcomas using three antibody clones: D5F3, 5A4, and ALK1.

March 2019—Using circulating cell-free fetal DNA to test for monogenic disorders: Screening for fetal chromosomal abnormalities can be performed by noninvasive methods in which fetal cell-free DNA (cfDNA) circulating in the maternal blood is isolated and analyzed. However, the standard of care for screening for monogenic diseases remains population-based carrier screening—testing the parents for their carrier status of deleterious genes.
