March 2023

March 2023—Updated classifications for hematologic neoplasms are here. Let the complications continue. As with other specialties, hematopathology has been absorbing advances gleaned from molecular and genetic data. In some cases, this can tilt diagnosis away from primarily immunophenotypic approaches. It might lead to splits in what was formerly a single entity. On occasion, it might suggest further testing options that could be of value to patients now, or possibly at a date down the road. Or it might just leave pathologists and their clinical colleagues peering at a lack of data, knowing they have to make decisions nonetheless. Two groups—the World Health Organization and the International Consensus Classification—have put forth classifications to help physicians sort through the complexities. The WHO published a beta version of the fifth edition of its Classification of Haematolymphoid Tumours in July 2022.

March 2023—A retrospective study of patients who received blood transfusions at 15 community hospitals found that just over half of the patient encounters reviewed could have been managed without the transfusion of at least one component type, and 45 percent could have been managed without any transfusion.

March 2023—With endometrial carcinomas and other gynecologic tumors, molecular testing matters, and not only at the diagnostic stage. “We’re rapidly evolving,” said Leslie M. Randall, MD, MAS, division director of gynecologic oncology, Virginia Commonwealth University Health, speaking at CAP22.

March 2023—When it comes to molecular syndromic panels for pneumonia, there’s both upside and downside, says Neil W. Anderson, MD, D(ABMM), associate professor, Department of Pathology and Laboratory Medicine, Washington University School of Medicine in St. Louis.

March 2023—All in on staff retention and solving staff shortages, some made worse temporarily by weather. That’s where laboratories were when Compass Group members told CAP TODAY publisher Bob McGonnagle in their Feb. 7 call where hospitals and labs were aiming their efforts. From safety huddles and stay interviews to arranging for overnight stays and incentives, the work to remain sufficiently staffed continues. The Compass Group is an organization of not-for-profit IDN system laboratory leaders who collaborate to identify and share best practices and strategies.

March 2023—The need was always there for some. For others, it’s a matter of convenience. “Home phlebotomy as a concierge service” is how Michael Eller describes what went live in 2019 in New York at Northwell Health, where he is assistant vice president of business development for its laboratories. “It was just a matter of using the capacity we already had in the field and hiring appropriately as needed,” he says.

March 2023—Assessing cardiac allograft rejection from endomyocardial biopsy​ and assigning a differential diagnosis to cancers of unknown origin have been shown to get a boost from AI-driven computational pathology models. So too has identifying subregions of high diagnostic value on whole slide images.

March 2023—Urinalysis was at the heart of a Feb. 7 discussion between CAP TODAY publisher Bob McGonnagle; Ron Jackups Jr., MD, PhD, of Washington University School of Medicine; and Jason Anderson of Sysmex America. “There’s a lot of room to explore what the optimal parameters are to use with the best specificity and sensitivity for a reflex to the sediment analysis or the culture,” Anderson said. Here’s what he and Dr. Jackups said about reflex testing, automation, and middleware.

March 2023—If you’ve read my prior columns, you know I am a strong advocate for pathologists stepping into leadership roles both within and outside the clinical laboratory. Our training gives us unique advantages as we serve in executive positions in health care, where our holistic view of medicine allows us to engage substantively on a broad range of issues. But what does that look like in the real world? I took on my first role as a hospital’s chief medical officer nearly two years ago and in some cases I’ve been surprised by how my day-to-day responsibilities differ from what I expected. Some of those surprises have been pleasant and some have not.  

March 2023—Coagulation screening prior to surgery for patients without a history of a bleeding disorder is controversial. Studies have recommended routine screening of prothrombin time/International Normalized Ratio (PT/INR) and activated partial thromboplastin time (aPTT) to reduce the risk of perioperative and postoperative hemorrhage. Other studies have questioned the value of coagulation screening tests, such as INR, aPTT, and platelet count, because it is rare to detect an abnormal value in patients undergoing elective surgeries. Many professional society guidelines, such as those of the American Society of Anesthesiologists and British Committee for Standards in Hematology, advise against routine perioperative coagulation screening prior to surgery for patients who do not have a clinical history of abnormal bleeding, medical history of comorbidity, or bleeding disorders. The authors conducted a study in which they examined the association between abnormal coagulation profile and risk of transfusion following common elective surgery in patients who did not have bleeding disorders. They used the National Surgical Quality Improvement Program (NSQIP) database for their retrospective cohort study, which focused on adult patients across multiple disciplines who underwent common surgical procedures between 2004 and 2018.  

March 2023—Prognostic stratification of patients with surgically resected invasive pulmonary adenocarcinoma must be improved. The authors conducted a study to evaluate the prognostic value of complex glandular patterns (CGPs) in patients with resected stage I through IV lung adenocarcinoma. The presence of CGPs as a minor to predominant component was tested for association with overall survival (n=676) and relapse-free survival (n=463) after surgery. CGPs were observed in 284 (42 percent) tumors. Cribriform and fused gland were the predominant patterns in 35 and 37 cases, respectively. The presence of a cribriform pattern was associated with worse relapse-free but not overall survival.  

March 2023—The Association for Molecular Pathology, American Society of Clinical Oncology, and College of American Pathologists published a formalized somatic variant classification system in 2017. The tiered system stratifies variants based on clinical importance, taking into account how variants affect cancer diagnosis, prognosis, or treatment strategies. Somatic variants with strong clinical significance, including those that are associated with FDA-approved therapies or included in professional guidelines, are tier one; variants with potential clinical significance are tier two; variants of unknown significance are tier three; and benign variants are tier four. The authors, members of the AMP Variant Interpretation Across Testing Laboratories Working Group, assessed how laboratories are using the AMP/ASCO/CAP guidelines and whether there is good concordance among laboratories in applying the guidelines to variant interpretation. A somatic variant interpretation challenge was sent to participating laboratories.  

March 2023—Whole slide imaging is increasingly being adopted by pathology laboratories worldwide. In 2013, the College of American Pathologists published guidelines on validating whole slide imaging (WSI) for diagnostic purposes. The CAP updated the recommendations in 2021. The guidelines include three strong recommendations and nine good-practice statements. The purpose of the validation guidelines is to ensure that a WSI system performs as intended in a particular clinical environment before it is used in patient care. In other words, the process is intended to make sure pathologists can render accurate diagnoses with WSI that are at least comparable to those provided via traditional light microscopy and that there are no interfering artifacts or technological risks to patient safety.
