December 2020—It can be difficult to distinguish metastatic melanoma from melanocytic nevi in lymph nodes. Because diffuse IHC PRAME (preferentially expressed antigen in melanoma) expression is detected in the majority of primary and metastatic melanomas, but rarely in nevi, the authors conducted a study in which they hypothesized that PRAME could be a useful adjunct marker for the diagnosis of melanocytes in lymph nodes. They examined 45 nodal melanocytic deposits comprising 30 nodal nevi and 15 melanoma metastases. The latter were not straightforward from a diagnostic perspective because they coexisted with nodal nevi or were present in perinodal fibrous tissue. All nodal nevi were negative for PRAME and all melanoma metastases were diffusely positive for PRAME IHC.

December 2020—Next-generation sequencing-based mutation testing of various cancer types is clinically indicated and widely used to diagnose disease, inform potential therapeutic targets, prognosticate disease course, and monitor responses to targeted and nontargeted therapies. The genetic variants discovered by tumor-based next-generation sequencing (NGS) can be somatically acquired by the neoplastic cells or a fixed inherited component of the patient’s germline genome. Distinguishing the germline versus somatic status of tumor NGS-defined variants is of significant clinical importance not only for patient care but possibly for patients’ families. Because many cancers have a substantial inherited component, the discovery of a pathogenic germline mutation by tumor-based NGS may have substantial familial implications. For example, being aware of a cancer risk allele, such as BRCA1, can lead to the use of highly effective interventions to prevent or treat the related cancer in family members. Consensus guidelines recommend germline genetic testing only for those cancer patients who have a clinical presentation or family history suggestive of hereditary disease.

Q. Can a heel stick for a basic metabolic panel with magnesium and phosphorus be performed on a two-month-old baby? Read answer.
Q. Due to nationwide supply shortages affecting COVID-19 and other testing in the laboratory, we are concerned about using up critical supplies when assessing competency. Do you have suggestions or strategies we can use? Read answer.
Q. When a patient is admitted to our hospital, we collect MRSA nares PCR, MRSA axilla by culture, MRSA groin by culture, and vancomycin-resistant Enterococcus by PCR for infection control purposes. Many surrounding facilities have told us they have removed the axilla and groin cultures, but no references were cited to support removing these procedures. Our facility would like to follow the practices of other hospitals, but our providers would like a reference to cite.

Are there best practices or benchmarks from an infection control and microbiology point of view that would allow us to remove the axilla and groin MRSA screen cultures? Read answer.

December 2020—Antimicrobial Susceptibility Testing: Monitoring and Trend Analysis is a new CAP program that is beginning to roll out to laboratories this month. The CDC guidance for antibiotic stewardship consists of seven core elements to address resistance-associated risks, one of which points to the importance of laboratory collaboration, communication, and AST reporting practices to the success of stewardship programs. According to this core element, the laboratory must provide information to guide discussions on the potential implementation of test interpretive criteria, such as changes in antibiotic breakpoints, that might affect antibiotic use.

Clinical pathology selected abstracts

November 2020—Smoking is a leading cause of death in the United States and is associated with many postoperative complications, including increased transfusion needs. Toxins in tobacco that create free radicals that damage the arterial walls and make them more susceptible to rupture and bleeding may be the link between smoking and surgical bleeding. Smoking also impairs tissue healing after surgery, most likely due to reduced oxygenation and altered function of inflammatory cells during the healing process. This may impact bleeding risk in the immediate postoperative period. The authors conducted a study in which they queried the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) Participant Use Data File 2007–2016, which contained data from up to 680 U.S. hospitals, to test the hypothesis that smoking is associated with a higher risk of bleeding in various surgical procedures.

Molecular pathology selected abstracts

November 2020—Sporadic vascular malformations are congenital malformations of arteries, veins, capillaries, or lymphatic vessels, or a combination of these, and are associated with significant morbidity. The majority of them are caused by postzygotic somatic pathogenic variants in oncogenes in the PI3K-MTOR and RAS-MAPK pathways, including within PIK3CA, TEK, MAP2K1, BRAF, and KRAS. Investigators have assessed whether therapeutic agents targeting these pathways should be used to augment or replace traditional surgical management. But because these somatic variants are restricted to cells within the tissue of vascular malformations (VM), it is necessary to conduct genetic testing on the surgically resected tissue to qualify patients for trials of targeted therapies. Approximately 10 percent of cell-free DNA (cfDNA) originates from endothelial cells.

November 2020—Neuroendocrine neoplasms range from well to poorly differentiated and indolent to highly aggressive. The site of origin in metastatic neuroendocrine neoplasms has therapeutic and prognostic implications. SATB2 is a transcriptional regulator involved in osteoblastic and neuronal differentiation and a sensitive and specific marker of colorectal epithelium. The authors conducted a study to evaluate the expression of SATB2 in neuroendocrine neoplasms from various primary sites and its utility as a marker for determining the site of origin of these neoplasms. SATB2 IHC was performed on 266 such neoplasms, including lung small cell carcinomas (n = 39) and carcinoids (n = 30), bladder (n = 21) and prostate (n = 31) small cell carcinomas, and gastrointestinal/pancreatic neuroendocrine neoplasms of various primary sites (n =145) consisting of well-differentiated neuroendocrine tumors (WDNET, n =124) and poorly differentiated neuroendocrine carcinomas (PDNEC, n = 21).

Pathology informatics selected abstracts

November 2020—Telepathology is a leading application for digital pathology. The ability to easily share a digital image in practice offers pathology laboratories clinical, operational, and financial benefits. This is best demonstrated by the longstanding success of telepathology in allowing pathologists to remotely perform intraoperative consultations—that is, to read frozen sections. Neuropathologists were one of the first specialists to leverage digital pathology for this clinical use. The authors, all of whom were from the University of Pittsburgh Medical Center, performed teleneuropathology at their institution, which implemented the practice 17 years ago.

Q&A column

Q. What can laboratories expect to see after a medication such as Narcan is given for an opioid overdose? Read answer.
Q. There are conflicting views among my colleagues regarding the meaning of initial competency assessment. Some think that using a training checklist for new staff counts as the initial competency assessment because we are signing off that staff are competent to perform patient testing and report results. Others believe an initial competency assessment is done shortly after training is completed, followed by the mid-cycle/six-month competency assessment and annual competency assessment. Please clarify. Read answer.
Q. How do you calculate RDW-SD and RDW-CV values in dimorphic anemia cases on the Sysmex XN-3000? Most of the dimorphic anemia cases report a masked parameter. Read answer.
