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.

May 2024—Massive hemorrhage is a major cause of death in children, and the mortality rate from life-threatening hemorrhage is estimated to be 20 to 51 percent. To counter this high mortality rate, clinicians have sought to standardize massive transfusion protocols and hemostatic resuscitation, ensuring that protocols support balanced blood-based resuscitation or the use of low titer group O whole blood, or both. These protocols may include using the lysine analogue antifibrinolytics tranexamic acid (TXA) and epsilon aminocaproic acid (EACA) in children with life-threatening hemorrhage (LTH). However, use of these antifibrinolytics is much more common in adult trauma patients. Study data suggest that TXA may increase survival outcomes in adults with traumatic injury, postpartum hemorrhage, nontraumatic intracranial hemorrhage, and all-cause bleeding.

May 2024—The Bethesda System for Reporting Thyroid Cytopathology described four subclasses of atypia within the atypia of undetermined significance category: nuclear (AUS-Nuc), architectural (AUS-A), oncocytic (AUS-Onc), and atypia not otherwise specified (AUS-NOS). Accumulating evidence supports the use of a binary AUS subclassification scheme based primarily on the presence of nuclear atypia only. The authors conducted a study to compare the risk stratification of binary versus four-tier AUS subclassification systems among AUS nodules with molecular or histologic follow-up, or both. The study included thyroid aspirates classified as AUS and tested using Afirma (Veracyte Inc.) between June 2013 and July 2021. Histological classification was considered the final outcome for resected nodules.

May 2024—Immunotherapy has revolutionized cancer treatment by recruiting the patient’s immune system to detect and destroy cancer cells. Immunotherapy often involves immune checkpoint blockade (ICB) agents, which target negative regulators of T-cell activation, such as cytotoxic T lymphocyte-associated protein 4 (CTLA-4), programmed cell death protein 1 (PD-1), or programmed death-ligand 1 (PD-L1). Although ICB is used to treat a variety of cancer types, patients’ response to therapy is often unpredictable, and biomarkers such as tumor mutation burden, mismatch repair deficiency, and IHC for PD-L1 have limitations for assessing ICB response. Consequently, there is great interest in discovering additional biomarkers that will improve the ability to predict clinical response to ICB. Recent studies have explored the hypothesis that there may be a correlation between a person’s gut microbiome and therapeutic response.

April 2024—Neonatal anemia is a common comorbidity of premature infants and may result from certain obstetric conditions or diseases, or, in the case of iatrogenic anemia, from multiple phlebotomies in the first days of life. Once infants enter the neonatal intensive care unit (NICU), they undergo a series of laboratory tests at baseline and then as needed for treatment or monitoring. These tests commonly include blood cultures, CBCs, coagulation profiles, metabolic screens, blood gases, blood glucose, and chemistry profiles. Phlebotomy-associated blood loss is more clinically relevant in lower birth-weight neonates since they have lower total circulating blood volumes. When blood is drawn from an indwelling umbilical catheter, even more blood is removed due to the need to flush residual intravenous fluid from the line.

April 2024—Fumarate hydratase-deficient renal cell carcinoma is a rare and distinct subtype of renal cancer caused by FH gene mutations. FH negativity and s-2-succinocysteine (2SC) positivity on IHC can be used to screen for FH-deficient renal cell carcinoma (RCC), but their sensitivity and specificity are imperfect. The expression of AKR1B10, an aldo-keto reductase that catalyzes cofactor-dependent oxidation-reduction reactions, in RCC is unclear. The authors compared AKR1B10, 2SC, and FH as diagnostic biomarkers for FH-deficient RCC. They included genetically confirmed FH-deficient RCCs (n=58), genetically confirmed TFE3 translocation RCCs (TFE3-tRCC; n=83), clear cell RCCs (n=188), chromophobe RCCs (n=128), and papillary RCCs (pRCC; n=97).

April 2024—Personalized medicine is revolutionizing cancer therapy, with targeted treatments customized to a person’s cancer-specific mutational profile leading to substantially improved health outcomes. Personalized medicine can also be applied to cancer prevention for high-risk groups based on genetic predisposition or lifestyle factors. However, there is a significant gap in cancer research resulting from a lack of equitable representation of racial and ethnic groups in cancer databases. Most research data are derived from white patients in the United States and Europe, creating racial disparities in understanding cancer development and therapies. The underrepresentation of patients of African, Asian, and Native American descent in observational, translational, and clinical cancer studies is particularly notable.

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.

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).

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.

February 2024—Patients receiving a pathology report may have many outstanding questions that can cause anxiety and confusion. The 21st Century Cures Act has increased patients’ access to pathology reports via delivery to patient portals. However, reports sent without further explanation can exacerbate the anxiety and confusion. Many health care institutions are creating new communication methods to help patients interpret these reports and develop a better understanding of their health status. One such approach is the pathology explanation clinic (PEC), which is an interactive visit between patients and pathologists to discuss the pathology report and review the patient’s slides.
