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.

May 2026—Two years after the Food and Drug Administration approved the first HPV self-collection devices, physicians and cervical cancer prevention advocates are debating the best use for the new screening option.
May 2026—The Papanicolaou test has been a model for cancer screening and prevention since its introduction well over half a century ago. Despite the evolution and innovations in HPV vaccination, testing methodologies, reporting systems, and treatment algorithms, cervicovaginal and lower genital tract cytology continues to be a workhorse for providers and laboratories.
May 2026—Digital pathology has evolved substantially over the past decade. What started primarily as a platform for image storage now supports educational initiatives, remote signout, consultation, and image analysis deployment.
May 2026—Education is one of the CAP’s core missions, closely linked to its commitment to advocacy and excellence in practice. In addition to its overarching laboratory improvement programs, the CAP provides educational offerings in a variety of formats, designed to satisfy the learning needs of its members and of a diverse group of laboratory professionals.
A recent article in Archives of Pathology & Laboratory Medicine emphasizes the importance of gender-inclusive care in cytopathology laboratories. The authors, members of the CAP Cytopathology Committee, identify four key areas for improvement: laboratory information systems and terminology, cervicovaginal Pap test screening, HPV testing, and anal Pap test screening. They advocate for gender-inclusive data entry, understanding changes from hormonal therapy, equitable access to HPV testing, and expanding anal Pap test screening infrastructure.
August 2025—Case summary. A 52-year-old chronic smoker with a known MLH1 mutation and Lynch syndrome presented with a pleural-based lung lesion. Fine-needle aspiration revealed a malignant neoplasm with papillary architecture, featuring enlarged overlapping nuclei, coarse chromatin, prominent nucleoli, and rare mitotic figures. Given the patient’s clinical background and cytologic findings, a broad differential diagnosis including primary and metastatic tumors from both thoracic and ab-dominal origins was considered.
August 2025—Strides in medical imaging techniques and procurement methods have led to the acquisition of small diagnostic samples obtained by minimally invasive techniques. Over the same period, the breadth of molecular information that can be derived from limited tumor material has increased exponentially. In the age of targeted cancer therapy, the clinical utility of this information is substantial and, when coupled with the decreasing costs of molecular analysis, the information transformed the treatment landscape of cancer. These advances have brought cytology back into the spotlight as a potential source of material for biomarker analysis.
August 2025—Human papillomavirus testing has become the standard of care in head and neck squamous cell carcinoma (HNSCC) because of the unique clinical features, staging, and treatment options for HPV-associated HNSCC. HPV-associated oropharyngeal squamous cell carcinoma (OPSCC) exhibits a favorable prognosis and improved response to chemoradiation compared with conventional HNSCC and non-HPV-associated forms, and reporting the HPV status is frequently part of clinical trial enrollments. Many patients with OPSCC present with enlarged level II or III cervical lymph nodes and, as a result, cervical lymph node fine-needle aspiration is often the first, and sometimes only, tissue obtained for diagnostic testing. With a growing menu of options available to test for HPV status, including polymerase chain reaction, DNA in situ hybridization, mRNA ISH, liquid-based HPV assays, and p16 immunohistochemistry, it is not always clear when and which HPV test to use, especially when the diagnosis is made on a cytology specimen.
May 2025—Granulomas are organized clusters of immune cells that form as part of the body’s chronic inflammatory response, typically triggered by persistent antigens, chronic infections, or immune dysregulation. They develop when macrophages are activated, transforming into epithelioid histiocytes and multinucleated giant cells (MGC) in response to ongoing immune stimulation. Granulomas are usually surrounded by T lymphocytes, fibroblasts, and extracellular matrix components. While granulomas are most often associated with infections or autoimmune conditions like sarcoidosis, they can arise in a variety of other processes, including malignancy.
May 2025—Claudin 18.2 (CLDN18.2), an isoform of claudin-18, is a transmembrane tight junction protein essential for maintaining barrier function and cell polarity in normal gastric and pancreatic epithelium. In malignant epithelial cells, the loss of polarity exposes the CLDN18.2 epitope, leading to its increased expression in gastric and pancreatic adenocarcinomas. CLDN18.2 has drawn attention as a therapeutic target, particularly with the development of the monoclonal IgG antibody zolbetuximab (Vyloy, Astellas Pharma). Zolbetuximab exerts its antitumor effects via both antibody-dependent and complement-mediated cytotoxicity and has demonstrated significantly improved progression-free and overall survival when combined with standard chemotherapy in two pivotal phase three clinical trials (SPOTLIGHT and GLOW). These data validated CLDN18.2 as a promising target in advanced, HER2-negative gastric and gastroesophageal junction (GEJ) adenocarcinoma.
