All Issues

For machine learning model use, turn to checklists

October 2024—Machine learning applications in molecular oncology testing are largely in the research or early clinical implementation phase, though some ML methods have been part of bioinformatics tasks for years, such as variant effect prediction.

Cyber safety and Epic installs: processes and problems

October 2024—Instrument assessments for cyber safety are in need of a fast track—or another solution to the delays they’re creating, say some Compass Group laboratory leaders. They met online on Sept. 3 with CAP TODAY publisher Bob McGonnagle, with whom they also talked about mergers and acquisitions and Epic Beaker transitions.

Large B-cell lymphoma with IRF4 rearrangement of retroperitoneal lymph node in an elderly male with concomitant high-grade B-cell lymphoma without IRF4r masquerading as a gastric ulcer

October 2024—CAP TODAY and the Association for Molecular Pathology have teamed up to bring molecular case reports to CAP TODAY readers. AMP members write the reports using clinical cases from their own practices that show molecular testing’s important role in diagnosis, prognosis, and treatment. The following report comes from Henry Ford Health. If you would like to submit a case report, please send an email to the AMP at amp@amp.org. For more information about the AMP and all previously published case reports, visit www.amp.org.

eGFR equations in the EHR—how lab met the request

October 2024—In patients at risk for chronic kidney disease, clinical practice guidelines released this year recommend the combined creatinine and cystatin C-based estimated glomerular filtration rate over the creatinine-based eGFR when cystatin C is available. “Cystatin C isn’t perfect itself, but a combination of the two seems to hit the sweet spot,” Angela Ferguson, PhD, D(ABCC), said in a session at the ADLM meeting in July. Dr. Ferguson is associate professor at the University of Missouri-Kansas City School of Medicine and co-director of clinical chemistry, director of immunology, and director of point-of-care testing in the Department of Pathology and Laboratory Medicine, Children’s Mercy Kansas City. The guidelines were released by the Kidney Disease: Improving Global Outcomes chronic kidney disease work group.

Can labs bridge the hematology data disconnect?

October 2024—Do clinicians understand how the technology in hematology has evolved and how laboratory data can help guide their decisions? It’s a question roundtable participants took on when they met online Aug. 29 with CAP TODAY publisher Bob McGonnagle. “There’s a disconnect with our clinical colleagues,” said Olga Pozdnyakova, MD, PhD, of the Hospital of the University of Pennsylvania. She and others spoke about solutions, instruments, AI, and reference ranges—in addition to the staffing shortage. “It is first and foremost in our minds,” Maria (Ria) Vergara-Lluri, MD, of Keck School of Medicine of USC, said of the ongoing shortage.

From the President’s Desk

October 2024—When this column comes out, many of us will be on our way to our annual meeting, held this year in Las Vegas. As I planned my presidential address for CAP24, I decided to focus on the future—the future of pathology and our future as pathologists. I’ll use this month’s column to cover the same theme. (And if some of you happen to read this column before I give my address, you will in a sense be seeing the future yourselves.)

Clinical pathology selected abstracts

October 2024—Exposure to lead is associated with irreversible adverse effects on fetal and neonatal development. Because no reliable threshold exists for determining the impact of lead exposure on children, the CDC began using the term blood lead reference values to identify children with higher blood lead levels (BLLs). Limiting exposure to lead is critical to ensuring that vulnerable populations, such as fetuses, neonates, and children, are not at risk for adverse neurodevelopmental outcomes. Lead and inorganic lead compounds are classified as carcinogens, while such metals as mercury and cadmium are considered neurotoxicants. Studies have shown a significant correlation between post-transfusion BLLs in infants and lead levels in RBC units.

Anatomic pathology selected abstracts

October 2024—Screening for colorectal cancers can involve assessing mismatch repair deficiency or microsatellite instability to identify people with Lynch syndrome, the most common hereditary syndrome causing colorectal cancer. Advanced adenomas are considered immediate precursor lesions of colorectal cancer. The authors conducted a study in which they investigated the relevance of microsatellite instability screening of advanced adenomas for Lynch syndrome in population screening. They selected advanced adenomas (n=1,572) from the Dutch colorectal cancer population screening program. All were reviewed and met one or more of the following criteria: tubulovillous (n=848, 54 percent) or villous (n=118, 7.5 percent) adenoma, diameter of 1 cm or more (n=1,286, 82 percent), or high-grade dysplasia (n=176, 11 percent).

Molecular pathology selected abstracts

October 2024—Huntington disease is a neurodegenerative disease caused by abnormal CAG trinucleotide repeats in exon one of the HTT gene, in which the number of CAG repeats affects disease presentation. Alleles with 40 or more CAG (cytosine, adenine, guanine) repeats are fully penetrant and age at disease onset is inversely correlated with number of repeats, while 36 to 39 CAG repeats are associated with reduced penetrance and fewer than 36 are not considered to cause Huntington disease. It is thought that inherited CAG repeats may undergo somatic expansion until a harmful threshold is reached before the degenerative process begins.
