Abstracts

Pathology informatics selected abstracts

September 2020—Whole slide imaging has been available for clinical, research, and educational use for decades, with several digital pathology systems cleared by the FDA for primary diagnosis. However, widespread adoption of this technology for routine practice has been slow. Likely reasons for the slow uptick in employing whole slide imaging (WSI) for sign-out include the cost of these systems, their lack of interoperability with laboratory information systems, pathologist resistance to using this digital modality, and regulatory restrictions on remote sign-out imposed by the Clinical Laboratory Improvement Amendments (CLIA). However, the COVID-19 pandemic led the Trump administration, on March 26, to temporarily waive these CLIA regulations, giving pathologists the flexibility to sign out cases digitally from their homes.

August 2020—Bacterial contamination of platelets continues to be an important cause of transfusion-associated morbidity and mortality. From 2001 to 2016, there were 51 deaths reported to the FDA due to transfusion of apheresis products contaminated with bacteria, including 30 deaths since testing for bacterial contamination was mandated in 2004. This mandate was implemented through primary culture of single-donor apheresis platelets in 2004 and then prestorage pooled platelets (PSPPs) in 2007. The authors conducted a study to compare the platelet bacterial contamination and septic transfusion rates before and after introducing testing of pooled and apheresis platelets by primary culture over an extended time period. They cultured platelet aliquots at issue and evaluated transfusion reactions.

August 2020—The authors conducted a study in which they reviewed 354 cases of malignant diffuse mesothelioma in women from a database of 2,858 histologically confirmed cases. Pleural predominance was noted with 78 percent of pleural malignant mesotheliomas (MM) and 22 percent of peritoneal MM. The pleural tumors consisted of 72 percent epithelioid, 19 percent biphasic, and nine percent sarcomatoid variant. The peritoneal tumors consisted of 82 percent epithelioid, 13 percent biphasic, and five percent sarcomatoid. The immunohistochemical profile was typical of what is well accepted and previously described for MM.

August 2020—Patients and families suspected of having Mendelian diseases, syndromes thought to be caused by a single mutated gene, often undergo comprehensive next-generation sequencing to determine the underlying pathogenic variant. Whole exome sequencing, in which the coding regions of all genes are analyzed, is usually the preferred testing method. However, this identifies the diagnostic pathogenic variant in only 25 to 52 percent of cases. Whole genome sequencing appears to confer only marginal benefit over whole exome sequencing, presumably because the pathogenic variants likely are not missed by whole exome sequencing but may be misinterpreted as nondiagnostic. Among the variants that are difficult to interpret are those that affect RNA by directly influencing transcription, or altering normal splicing, or by mediating their effects through chromatin.

July 2020—The College of American Pathologists launched the Pathology and Laboratory Quality Center for Evidence-Based Guidelines in 2009 to develop and promote laboratory practice guidelines (LPGs) using the National Academy of Medicine’s (NAM) standards for developing trustworthy guidelines. The center has published 17 evidence-based LPGs, including updated versions, using NAM’s criteria. In 2013, the CAP was awarded a five-year cooperative agreement grant from the Centers for Disease Control and Prevention to increase the effectiveness of its LPGs. The intent of the agreement was to assess awareness and adoption of two CAP LPGs: IHC assay validation (IHC VAL) and initial workup of acute leukemia (AL).

July 2020—Smooth muscle tumors represent the second most common mural mesenchymal neaoplasm in the gastrointestinal tract, yet established criteria for prognostically assessing these tumors are lacking. The authors conducted a study on a large cohort of surgically resected intramural gastrointestinal smooth muscle tumors from 31 institutions to identify potential prognostic features. At each location, expert gastrointestinal or soft tissue pathologists, or both, assessed pathologic features. IHC confirmation was required.

July 2020—Drug-induced hypersensitivity syndrome/drug reaction with eosinophilia and systemic symptoms (DiHS/DRESS) is a rare but well-known full-body inflammatory skin condition that leads to life-threatening complications if untreated. The authors conducted a case study that involved a 44-year-old male who developed DiHS/DRESS after taking the combined antibiotic trimethoprim-sulfamethoxazole. Following standard treatment for this condition, the patient was started on high-dose prednisone, which provided no benefit. Subsequent tapering of prednisone advanced the disease to a toxic epidermal necrolysis-like condition. The patient was then given etanercept and high-dose intravenous immunoglobulin, without benefit. Next, the patient received cyclosporine, which resulted in some improvement but led to uncontrollable renal hypertension.

June 2020—More than 1.7 million new diagnoses of cancer occur in the United States each year, and they are almost exclusively made by pathologists who evaluate patient specimens and issue a written diagnostic report. These patients often are not given the opportunity to talk with the pathologist who made the diagnosis or view their tissue through a microscope. There is little published data on patient-pathologist consultation programs in which patients can review their reports and slides with the pathologist. In addition, the number of patients who may be interested in this service is not known. The authors conducted a study to quantify patients’ interest in patient-pathologist consultation programs and qualitatively analyze their motivations for interest or disinterest.

June 2020—The authors conducted a study in which they independently evaluated the utility and prognostic value of tumor budding according to International Tumour Budding Consensus Conference (ITBCC) criteria in a large well-characterized European gastric cancer cohort. They assessed tumor budding according to the ITBCC criteria for 456 consecutive, surgically treated gastric cancers using the scoring system Bd0 (no buds), Bd1 (one to four buds), Bd2 (five to nine buds), and Bd3 (10 or more buds). Cases with tumor budding were divided into low-budding (Bd1/Bd2) and high-budding (Bd3) groups. The tumor budding score was analyzed in relation to clinicopathological parameters, overall survival, and tumor-specific survival. The authors found that 115 (25.2 percent) cases had no tumor budding, 104 (22.8 percent) had low tumor budding, and 237 (52 percent) had high tumor budding.

June 2020—The COVID-19 pandemic has focused the world’s attention on using sensitive high-throughput molecular diagnostic testing for the SARS-CoV-2 virus as a public health tool for “flattening the curve” of the infection. Although initial shortages of specialized polymerase chain reaction (PCR) testing reagents that plagued the early weeks of the pandemic have slowly improved (as of CAP TODAY press time), an obstacle to universal testing continues to be the first-step bottleneck of collecting respiratory tract samples for virus-specific reverse transcriptase-PCR (RT-PCR) testing. The traditional gold standard sample for COVID-19 testing has been a nasopharyngeal (NP) swab. However, nationwide shortages of NP swabs, personal protective equipment (PPE), and viral transport media have intermittently delayed the testing process. In an attempt to alleviate these critical sample-collection issues and promote more widespread testing, the medical community and other entities have been investigating alternative sample-collection procedures.
