April 2024—Transitioning to digital pathology can seem complex and costly. And for some, but not all, laboratories, cost in particular can be a barrier to adoption. So how do you determine which camp your lab falls into? You calculate, according to Orly Ardon, PhD, director of digital pathology operations at Memorial Sloan Kettering Cancer Center.

Q&A column

April 2024
Q. Ordering clinicians are requesting that our laboratory flag abnormally high absolute neutrophil counts (ANC) on peritoneal fluids. We cannot find sources for reference ranges, but there is literature that states that a polymorphonuclear cell count greater than 250/μL is a reliable discriminatory test for bacterial peritonitis. We would like to use this as our reference and flag results with an ANC greater than 250 cells/μL as abnormally high. Is this acceptable? Read answer.

Q. How do you code fallopian tubes submitted for sterilization with a finding of a paratubal cyst? Read answer.

April 2024—The article “Test adds twists to lung disease diagnosis” (November 2023, page 1) virtually ignores the major problem of clinicians in the hospital thinking that it is perfectly okay to take specimens from patients in the hospital and send them directly to whatever laboratory they choose without input from the hospital’s laboratory administration or medical director. The laboratory medical director is legally responsible for approving the menu of laboratory tests to be performed in-house and all of the reference laboratories to be used.

Put It on the Board

April 2024—Member organizations of the Enduring Consensus Cervical Cancer Screening and Management Guidelines effort released in March their recommendations for the use of p16/Ki-67 dual stain for managing individuals who test positive for HPV.

From the President’s Desk

March 2024—During the 12 years I spent as director of a pathology residency program, one thing I worried about was how to better prepare our residents for their first roles as attending pathologists or laboratory directors. For many pathologists, the transition from always having someone looking over their shoulder to being on their own is very challenging.

Clinical pathology selected abstracts

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.

Anatomic pathology selected abstracts

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).

Molecular pathology selected abstracts

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.

Q&A column

March 2024
Q. Is it a requirement that routine bacteriology cultures (for example, urine, sputum) be plated in a biological safety cabinet in your typical hospital biosafety level 2 laboratory? Is it safe to read these cultures on an open bench? Read answer.

Q. What source should a laboratory use for reference intervals for analytes? Read answer.

March 2024—While Dr. Seuss’ assertion that “the more that you read, the more things you will know” is generally accurate, it doesn’t address the fact that how information is presented affects comprehension, a truism that is not lost on Edward Klatt, MD, who knows whereof he speaks when it comes to sharing information on patient portals.
