This session is designed to improve understanding and application of recent updates to synoptic pathology reporting protocols such as the latest Reporting Template for Reporting Results of Biomarker Testing of Specimens from Patients with Carcinoma of the Breast. These changes reflect evolving clinical guidelines that directly influence diagnostic accuracy and treatment selection in breast cancer care.

Webinar presenters Thaer Khoury, MD, FCAP, Chair, Pathology and Laboratory Medicine, Roswell Park Comprehensive Cancer Center, and Colin Murphy,  CEO of mTuitive.

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

Anatomic pathology selected abstracts

December 2023—Cytomegalovirus hepatitis in allograft livers is a significant infectious complication for which the histology historically has been described as overlapping that of acute cellular rejection, a diagnosis that compels a different treatment regimen. The authors conducted a study to update the clinicopathologic features of cytomegalovirus (CMV) hepatitis and explore its clinical and histologic relationship with acute cellular rejection (ACR). They performed a retrospective analysis of 26 patients, across four institutions, who were diagnosed with CMV hepatitis, assessing clinical, histologic, and IHC features. Patients were predominantly CMV donor positive/recipient negative (D+/R-; n=9 of 15) and received a diagnosis of CMV hepatitis at a mean age of 52 years (standard deviation [SD], 17 years) and at a mean interval of 184 days (SD, 165 days) from transplantation. Mean CMV viral load at diagnosis was 241,000 IU/mL (SD, 516 000 IU/mL), and liver biochemical enzymes were elevated (mean alanine aminotransferase, 212 U/L [SD, 180 U/L]; mean aspartate aminotransferase, 188 U/L [SD, 151 U/L]; and mean alkaline phosphatase, 222 U/L [SD, 153 U/L]).

Clinical pathology selected abstracts

December 2023—Efforts to develop biomarkers that help predict risk factors for preeclampsia/eclampsia and to better understand the trends and implications related to new-onset hypertensive disorders in pregnancy have grown. New-onset hypertension arising during pregnancy (gestational hypertension and preeclampsia/eclampsia) is associated with coronary heart disease, heart failure, stroke, and other cardiovascular-related mortality. Hypertensive disorders of pregnancy have grown into major public health problems that contribute to maternal morbidity, mortality, and future risk of cardiovascular disease. The authors conducted a study to describe contemporary trends in new-onset hypertensive disorders of pregnancy in the United States. They conducted a serial cross-sectional analysis of 51,685,525 live births to women aged 15 to 44 years, from 2007 to 2019, using the Centers for Disease Control and Prevention’s natality database.

Molecular pathology selected abstracts

December 2023—Immune checkpoint blockade therapy has dramatically altered treatment options for a variety of cancers. A high tumor mutation burden (TMB) is considered one of the strongest predictors of immune checkpoint blockade response. DNA mismatch repair deficiency (MMRd) is associated with a high TMB, and many tumors associated with MMRd have shown excellent response to immunotherapy. However, most MMRd tumors do not show durable response to treatment with immune checkpoint blockade (ICB). Intratumor heterogeneity may further mediate response to ICB therapy.

Q&A column

December 2023
Q. When using a sodium citrate blue-top tube due to platelet clumping, should the sample be kept warm, and does it have to be run within a certain time frame? Read answer.

Q. Does the CAP require instrument-to-instrument comparability studies at least twice a year for waived point-of-care testing instruments, such as glucose meters, or nonwaived instruments, such as critical care analyzers? Are we required to perform a linearity study twice a year on all waived and nonwaived POC testing instruments? Read answer.

Verichem reference materials for serum and urine testing

November 2023—Verichem Laboratories announced the availability of its Urine Uric Acid Standard kit, Matrix Plus Cholesterol Reference kit, and a standalone, ultra-high Matrix Plus Cholesterol Reference level F for the calibration verification testing of cholesterol and urine and serum uric acid assays. The Urine Uric Acid Standard kit is a five-level kit with uric acid concentrations ranging from 1 to 101 mg/dL. The materials feature universal testing compatibility and are composed of a biosynthetic matrix with urine-like activity. Storage temperature is −15° to −25°C and Verichem says the product can tolerate up to 10 freeze-thaw cycles with no effect on accuracy or performance. Shelf life is 19 months.
