March 2025

Anatomic pathology selected abstracts

March 2025—Invasive lobular carcinoma is characterized by loss of E-cadherin expression and CDH1 gene inactivation. The reliability and reproducibility of diagnosis for this tumor type is suboptimal and could be improved by better understanding the histomolecular and clinical heterogeneity of such tumors. The authors analyzed the relationship between the presence, type, or position of CDH1 mutations, E-cadherin expression, and clinicopathological features, including outcome, in a retrospective series of 251 primary invasive lobular carcinomas (ILC) with a median follow-up of 9.5 years. The mutational status of CDH1 (the gene encoding E-cadherin) was determined by RNA sequencing of frozen tumor samples. E-cadherin immunohistochemistry was performed with antibodies directed against the intracellular (clone 4A2C7) and extracellular (clone NCH38) domains.

Molecular pathology selected abstracts

March 2025—Genomic imprinting is an epigenetic process that results in expression of only one copy of a gene—either from a person’s mother or father—while the other parent’s copy of the same gene is silenced. A cluster of genes affected by imprinting on the proximal part of the long arm of chromosome 15 (15q11-q13) are associated with syndromic conditions. Deficient expression of the maternally inherited copy of UBE3A in this region results in Angelman syndrome, which is characterized by severe developmental delay, gait ataxia, and an apparent happy demeanor with profuse smiling, frequent laughing, and excitability. In contrast, deficient expression of paternally inherited genes in this region causes Prader-Willi syndrome. Clinical features of this condition can vary but often include developmental delay, short stature, hyperphagia, and obesity.

March 2025—Delays while a courier is sent to the blood bank. Errors in judgment. Omission of steps in tracking who received a unit of blood. Wastage of blood product because clinicians were cautious and overordered or ordered too soon. Staffing issues. All of these potential blood bank-related problems can be mitigated with smart blood-storage devices, also called smart refrigerators or blood vending machines.

Put It on the Board

March 2025—The Roche Tina-quant Lipoprotein (a) Gen.2 Molarity assay received 510(k) clearance from the Food and Drug Administration. It is the first 510(k)-cleared test of its kind available in the U.S. to measure lipoprotein(a) in nanomoles per liter. It will be broadly available on Cobas c analyzers. Lp(a) can vary in size and has no single, defined molecular weight. For this reason, Roche says, there is a consensus in the scientific community that Lp(a) levels should be measured in terms of the number of particles per liter of blood (nmol/L), rather than mass units (mg/dL), and that any conversion between mass and molar units is generally imprecise and unreliable. By using molar units, laboratory professionals and clinicians know the Lp(a) measurements reflect the number of particles rather than a difference in particle size.
