Toward a Platform for Structured Data Acquisition in Oncology: A Pilot Study on Prostate Cancer Screening.

INTRODUCTION: Physicians spend an ever-rising amount of time to collect relevant information from highly variable medical reports and integrate them into the patient's health condition. OBJECTIVES: We compared synoptic reporting based on data elements to narrative reporting in order to evaluate its capabilities to collect and integrate clinical information. METHODS: We developed a novel system to align medical reporting to data integration requirements and tested it in prostate cancer screening. We compared expenditure of time, data quality, and user satisfaction for data acquisition, integration, and evaluation. RESULTS: In a total of 26 sessions, 2 urologists, 2 radiologists, and 2 pathologists conducted the diagnostic work-up for prostate cancer screening with both narrative reporting and the novel system. The novel system led to a significantly reduced time for collection and integration of patient information (91%, p < 0.001), reporting in radiology (44%, p < 0.001) and pathology (33%, p = 0.154). The system usage showed a high positive effect on evaluated data quality parameters completeness, format, understandability, as well as user satisfaction. CONCLUSION: This study provides evidence that synoptic reporting based on data elements is effectively reducing time for collection and integration of patient information. Further research is needed to assess the system's impact for different patient journeys.

Recommendations for Clinical CYP2D6 Genotyping Allele Selection: A Joint Consensus Recommendation of the Association for Molecular Pathology, College of American Pathologists, Dutch Pharmacogenetics Working Group of the Royal Dutch Pharmacists Association, and the European Society for Pharmacogenomics and Personalized Therapy.

The goals of the Association for Molecular Pathology Clinical Practice Committee's Pharmacogenomics (PGx) Working Group are to define the key attributes of pharmacogenetic alleles recommended for clinical testing, and to determine a minimal set of variants that should be included in clinical PGx genotyping assays. This document series provides recommendations on a minimal panel of variant alleles (Tier 1) and an extended panel of variant alleles (Tier 2) that will aid clinical laboratories in designing assays for PGx testing. When developing these recommendations, the Association for Molecular Pathology PGx Working Group considered the functional impact of the variant alleles, allele frequencies in multiethnic populations, the availability of reference materials, as well as other technical considerations with regard to PGx testing. The ultimate goal of this Working Group is to promote standardization of PGx gene/allele testing across clinical laboratories. This document is focused on clinical CYP2D6 PGx testing that may be applied to all cytochrome P450 2D6-metabolized medications. These recommendations are not meant to be interpreted as prescriptive but to provide a reference guide for clinical laboratories that may be either implementing PGx testing or reviewing and updating their existing platform.

The right to mourn: Post-traumatic stress and the forensic pathologist.

Post-traumatic stress disorder (PTSD) is a condition characterised by recurrent intrusive distressing memories of a traumatic event(s) with recurrent dreams and flashbacks. Given the nature of standard forensic pathology practice which involves on-going assessments of violent crimes and their sequelae with autopsy dissections of victims and in detail study of injuries, it is surprising that more has not been written on this in the literature. Perhaps PTSD should be studied further in a forensic context with a recognition that years of intimate exposure to violence may lead to accumulated, ongoing and unresolved grief in practitioners.

Molecular targets in GI malignancies - A pathologist's perspective.

Newer molecular diagnostics and improved understanding of cancer pathogenesis have identified multiple pathways that can be potentially targeted with the use of novel therapeutics in development. These developments have ushered cancer therapeutics in newer era of personalized medicine. Same is reflected on current management strategies for advanced gastrointestinal malignancies. Molecular profiling for BRAF and RAS is standard for colorectal cancer while Her2 and PDL1 status is needed for planning therapy of advanced gastroesophageal cancers. Tissue agnostic markers like MSI, TMB and NTRK are making headways in therapeutic armamentarium. While newer targeted therapies against FGFR, EGFR, PI3K-AKT, DDR pathways are showing promising results in initial studies. Here we review traditional as well as upcoming molecular markers in field of GI malignancies, methods of testing and evidence for rational use in clinical practice.

Global approaches to cardiogenetic evaluation after sudden cardiac death in the young: A survey among health care professionals.

BACKGROUND: Thorough investigation of sudden cardiac death (SCD) in those aged 1-40 years commonly reveals a heritable cause, yet access to postmortem genetic testing is variable. OBJECTIVE: The purpose of this study was to explore practices of postmortem genetic testing and attitudes of health care professionals worldwide. METHODS: A survey was administered among health care professionals recruited through professional associations, social media, and networks of researchers. Topics included practices around postmortem genetic testing, level of confidence in health care professionals' ability, and attitudes toward postmortem genetic testing practices. RESULTS: There were 112 respondents, with 93% from North America, Europe, and Australia/New Zealand, and 7% from South America, Asia and Africa. Only 30% reported autopsy as mandatory, and overall practices were largely case by case and not standardized. North American respondents (87%) more often perceived practices as ineffective compared to those from Europe (58%) and Australia/New Zealand (48%; P = .002). Where a heritable cause is suspected, 69% considered postmortem genetic testing and 61% offered genetic counseling to surviving family members. Financial resources varied widely. Half of participants believed practices in their countries perpetuated health inequalities. CONCLUSION: Postmortem genetic testing is not consistently available in the investigation of young SCD despite being a recommendation in international guidelines. Access to postmortem genetic testing, which is critical in ascertaining a cause of death in many cases, must be guided by well-resourced, multidisciplinary teams.

Remote cytological diagnosis of salivary gland lesions by means of precaptured videos.

OBJECTIVE: The objective of this study was to investigate the feasibility of implementing videos captured by static telecytological applications for remote cytological diagnosis of fine needle aspiration (FNA) specimens from salivary gland lesions. METHODS: The current study was performed on 102 specimens from patients referred to the Alpha Prolipsis Cytopathology Department for preoperative evaluation of salivary gland lesions. In all cases, surgical excision followed the initial cytological diagnosis. (benign lesions, 11; benign neoplasms, 68; malignant neoplasms, 23). Videos were transferred via file transfer protocol to password-protected accounts for remote review by three independent cytopathologists. In addition to diagnosis, reviewers commented on overall digital video quality. Contributor's and reviewer's diagnoses were collected, recorded and statistically evaluated. RESULTS: Statistical evaluation of cytological diagnoses detected no significant difference in diagnostic accuracy between the diagnoses proffered on the basis of precaptured videos and conventional slides. The overall interobserver agreement was ranging from substantial to almost perfect with κ values of 0.71-0.89. CONCLUSIONS: Videos production by static telecytology applications can be used as an alternative method for telecytological diagnosis of salivary glands FNAs. Videos of salivary glands FNAs can be used for accurate diagnosis, educational and second opinion purposes,. They can also be used for archiving, teleconsultation and educational purposes, improving the performance of the already existing static telecytology stations and small cytology departments' quality indices.

How Does It Feel to Be a Pathologist in Turkey? Results of a Survey on Job Satisfaction and Perception of Pathology.

OBJECTIVE: Job satisfaction affects productivity and professional performance in many aspects; however, there is limited data regarding pathologists' job satisfaction. Hence, in this study, we aimed to evaluate surgical pathologists' job satisfaction in Turkey. MATERIALS AND METHODS: We conducted a 59-item web-based survey questioning respondents' institutional background, history of training, continuing education status/research activities, physical conditions, professional well-being, and job satisfaction level. Likert-type and open/ close ended questions were asked and scored. The participants were also asked to complete the Minnesota Satisfaction Questionnaire-Short Form. RESULTS: Of the 321 respondents, 75% were female, the median age was 41 years (range 28-71 years), experience as a pathologist ranged between 0.12 and 44 years (mean 11.4±9.16 years). Academic pathologists, senior pathologists with ≥20 years of experience, and pathologists working at large institutions and living in developed cities expressed better physical conditions, higher satisfaction with working conditions and, therefore, higher overall job satisfaction (p < 0.05). 98% agreed that pathologists have a critical impact on patient management; however, the majority ( > 80%) thought that patients barely know what pathologists do and other physicians rarely understand the difficulty and limitations in pathology practice. 82% were happy to have chosen pathology but 45% reported to experience the feeling of being "burnt out". CONCLUSIONS: Our findings suggest that younger pathologists are less satisfied with their jobs and a surgical pathologist's job satisfaction increases with the physical and technical quality of the pathology laboratory/institution, and years of experience. Pathologists seem to be aware of their important role in patient management although they think that pathology remains "invisible" to many physicians and patients.

Impact of clinical photographs on the accuracy and confidence in the histopathological diagnosis of mycosis fungoides.

BACKGROUND: The histopathological diagnosis of MF is challenging, and there is significant overlap with benign inflammatory processes. Clinical features may be relevant in the assessment of skin biopsies. METHODS: We provided photomicrographs to board-certified dermatopathologists and one hematopathologist with and without accompanying clinical photographs and assessed accuracy and confidence in diagnosing MF. RESULTS: We found that access to clinical photographs improved diagnostic accuracy in both MF and non-MF (distractors); the degree of improvement was significantly higher in the non-MF/distractor category. Across all categories, diagnostic confidence level was higher when clinical images were available. CONCLUSION: These findings suggest that clinical images are useful in making an accurate diagnosis of MF, and may be particularly helpful in ruling it out when an inflammatory disorder is clinically suspected.

Terminology for melanocytic skin lesions and the MPATH-Dx classification schema: A survey of dermatopathologists.

BACKGROUND: Diagnostic terms used in histopathology reports of cutaneous melanocytic lesions are not standardized. We describe dermatopathologists' views regarding diverse diagnostic terminology and the utility of the Melanocytic Pathology Assessment Tool and Hierarchy for Diagnosis (MPATH-Dx) for categorizing melanocytic lesions. METHODS: July 2018-2019 survey of board-certified and/or fellowship-trained dermatopathologists with experience interpreting melanocytic lesions. RESULTS: Among 160 participants, 99% reported witnessing different terminology being used for the same melanocytic lesion. Most viewed diverse terminology as confusing to primary care physicians (98%), frustrating to pathologists (83%), requiring more of their time as a consultant (64%), and providing necessary clinical information (52%). Most perceived that adoption of the MPATH-Dx would: improve communication with other pathologists and treating physicians (87%), generally be a change for the better (80%), improve patient care (79%), be acceptable to clinical colleagues (68%), save time in pathology report documentation (53%), and protect from malpractice (51%). CONCLUSIONS: Most dermatopathologists view diverse terminology as contributing to miscommunication with clinicians and patients, adversely impacting patient care. They view the MPATH-Dx as a promising tool to standardize terminology and improve communication. The MPATH-Dx may be a useful supplement to conventional pathology reports. Further revision and refinement are necessary for widespread clinical use.

Social Media for Hematopathologists: Medical Practice Reinvented-#Hemepath.

PURPOSE OF REVIEW: Social media engagement by medical professionals with varied background subspecialties has steadily gained popularity in recent years. As a heavily visual discipline, pathology has been able to leverage social media platforms for trainee education, curbside and official consultations, interdisciplinary communication, and interactions among medical professionals and patient education. The pathology community has been at the forefront of using social media as an educational forum, and the hematopathology community has emerged as one of the strongest and most influential presences on these online platforms. In this review, we perform an in-depth analysis of various Twitter metrics to demonstrate key trends in the usage of social media as it pertains to hematopathology using the hashtag #Hemepath and we describe specific details on how hematopathologists have managed to take advantage of Twitter in furthering our mission of advancing medical education and disseminating knowledge using these innovative virtual educational experiences. RECENT FINDINGS: The hematopathology community has a great degree of enthusiasm among residents, fellows, and faculty in sharing educational material using case-based examples, participating in group-based online activities, introducing new publications by article authors or readership, and disseminating educational "pearls" from medical conferences, using hashtags and digital images that otherwise would not be readily available to many around the globe. This practice is helping reshape the structure of our field and is providing opportunities to optimize the educational experience by enhancing the instant exposure to cutting-edge information and expert opinions, among other valuable features. The hematopathology community has leveraged social media platforms for disseminating educational material and strengthening interdisciplinary interactions and is a "poster child" for a medical subspecialty that has thrived and flourished by more broadly adopting virtual educational platforms. We hope that this review will provide details on how social media platforms can be used by others in the medical field to achieve similar goals.

The utility of fine-needle aspiration: how FNA has affected our musculoskeletal oncology practice.

Fine-needle aspiration (FNA) has been a widely accepted practice in the diagnosis of head and neck, thyroid, lung, pancreas, and many other visceral sites. This has not been the case with the diagnosis of primary bone and soft tissue lesions. FNA has been an important part of our orthopaedic oncology practice for 18 years. Our ability to efficiently and effectively care for patients dramatically improved when FNA became an option for obtaining a tissue diagnosis. We discuss the advantages and disadvantages of a pathologist-driven FNA service in orthopaedic oncology.

Results from the 2019 American Society of Cytopathology survey on rapid onsite evaluation (ROSE)-part 2: subjective views among the cytopathology community.

INTRODUCTION: This study aims to improve understanding of the cytopathology community's perspective regarding the value of rapid onsite evaluation (ROSE) in clinical practice. MATERIALS AND METHODS: The American Society of Cytopathology membership was surveyed in 2019 to obtain subjective data on the cytopathology community's perceptions regarding ROSE. Comments were categorized by major themes and attitudes and analyzed by respondent's role in laboratory, practice size, and practice setting (Fisher's exact and χ2 tests). RESULTS: A total of 541 responses were received from 255 cytopathologists/pathologists, 261 cytotechnologists, 19 trainees, and 6 others (as previously reported). Reasons for which cytopathology personnel provide this service aligned with their perceptions of why clinicians request ROSE. A minority of respondents, disproportionally from high volume centers, felt ROSE is unnecessary. Overall attitude regarding ROSE was generally positive. There were no significant differences in attitude regarding ROSE according to role in laboratory or practice size, but respondents from academic centers provided a significantly higher percentage of positive comments than those in private or community practice. Although survey respondents generally felt that ROSE is valuable to patient care, they also highlighted several challenges, including staffing, time commitment, and inadequate reimbursement. Implementation of telecytology was felt to potentially alleviate some of these challenges. CONCLUSIONS: Survey results show that the cytology community views ROSE favorably, practices vary considerably, and there is a perceived need for improved reimbursement. Data from this study may be used to identify areas that warrant additional research to clarify the clinical value of ROSE.

Small core needle biopsies in cytology practice: a survey of members of the American Society of Cytopathology.

INTRODUCTION: The introduction of a new generation of core needle biopsies (CNBs) for endoscopic procedures has prompted reconsideration of the role of cytopathologists in the handling of small biopsies. The American Society of Cytopathology (ASC) has therefore conducted a survey with the intention of elucidating current practices regarding the handling of small CNBs. MATERIALS AND METHODS: The membership of the ASC was invited by email to participate in an online survey over a 2-month period. The survey consisted of 20 multiple choice questions with 2-8 possible responses per question. RESULTS: Of 2651 members contacted by e-mail, 282 (10.6%) responded to the survey questions, including 196 pathologists (69.5%) and 86 cytotechnologists (30.5%). Of these, 265 respondents were from the US/Canada (94.0%), with 156 from academic institutions (58.9%) and 109 from non-academic practices (41.1%); 17 were from other countries (6.0%). In 18.8% of all practices, cytopathologists sign out >90% of small CNBs from endoscopic and radiologically guided procedures; in 36.5% of practices >90% are signed out by surgical pathologists; the remainder have such cases divided more evenly between cytopathologists and surgical pathologists. Responses show that 78.0% of all respondents are interested in signing out more small biopsies in the future, and 80.5% desire increased small biopsy-related resources from the ASC. CONCLUSIONS: The survey responses indicate that practices currently vary widely across institutions. Most indicated an interest in greater incorporation of small biopsies into the practice of cytopathology.

Oil red O staining for lipid-laden macrophage index of bronchoalveolar lavage: interobserver agreement and challenges to interpretation.

INTRODUCTION: Oil Red O (ORO) staining on cytologic specimens with calculation of the lipid-laden macrophage index (LLMI) is used as a part of the workup in a number of clinical settings, particularly when aspiration is of concern. As a part of ongoing internal quality improvement measures, the objective of the present study was to evaluate the interobserver agreement of the LLMI calculation and to identify factors that affect the variability of the calculation. MATERIALS AND METHODS: There were 9 study participants, which included 3 trainees, 3 cytotechnologists, and 3 cytopathologists. Each participant reviewed 100 ORO-stained bronchoalveolar lavage slides and assigned an LLMI score to each case. The scores were categorized into 3 groups according to the associated aspiration risk: low, LLMI <40; intermediate, LLMI 40 to 90; and high, LLMI >90. The participants were also requested to note any challenges to the calculation for each case. RESULTS: The interobserver agreement among all participants was fair (κ = 0.23). Stratified by participant group, the interobserver agreement among the trainees was fair (κ = 0.24), among cytotechnologists was fair (κ = 0.32), and among cytopathologists was moderate (κ = 0.60). In 70 cases, at least one participant scored the case at least one category higher than the other participants; in 47 cases there was a two category difference. A primary diagnostic challenge reported by participants was macrophage pigmentation (hemosiderin, anthracosis). CONCLUSIONS: We found only fair interobserver agreement among all 9 participants in the study. Hemosiderin and anthracotic pigmentation was a major factor impeding LLMI calculation resulting in overestimation of the LLMI.

Small but powerful: the promising role of small specimens for biomarker testing.

Emphasis on the use of small specimens for biomarker testing to provide prognostic and predictive information for guiding clinical management for patients with advanced-stage cancer has been increasing. These biomarker tests include molecular analysis, cytogenetic tests, and immunohistochemical assays. Owing to the limited nature of the cellular material procured in these small specimens, which are collected using minimally invasive techniques (ie, fine needle aspiration and core needle biopsy), pathologists have been required to triage these samples judiciously and provide the clinically relevant genomic information required for patient care. Awareness of the advantages and limitations of these specimen preparations and the specific preanalytic requirements for the testing methods will help pathologists to develop optimal strategies to maximize the chances of effectively using these samples for comprehensive diagnostic and relevant biomarker testing.

An international outreach from the American Society of Cytopathology: Worldvision Cytopathology Contest.

In an effort to be more inclusive and embrace the international cytology community, the American Society of Cytopathology formed the International Liaison and Membership (ILM). The Worldvision Cytopathology Contest was designed by the co-chairs of this committee (Drs. Güliz A. Barkan and Esther Diana Rossi) as an opportunity of scientific exchange in the international cytology community. The idea took its inspiration from the well-known song contest, the "Eurovision Song Contest" a competition among international singers, which started as a "light entertainment" in the 1950's to bring together a war-torn Europe. The goals of this session were to bring the worldwide cytology community together, to increase the international participation to the ASC, to attract a younger generation of pathology professionals to cytopathology, to provide education on interesting cases for the participants, and to provide training for international contestants on how to give good public presentations. The contest was successfully done at the 2019 annual meeting, and the winner was Dr. Elena Vigliar from Italy. The Worldvision Cytopathology Contest will be performed again in future meetings.

Core needle biopsy with endobronchial ultrasonography: single center experience with 100 cases.

INTRODUCTION: Adequate sampling by endobronchial ultrasound (EBUS)-transbronchial needle aspiration to meet the demands of precision medicine or histologic evaluation is challenging. There is increasing demand for core biopsy specimens with advances in therapy. Franseen enodoscopic ultrasound needles have shown promising results in gastroenterology application for obtaining core biopsies and same design has recently been extended for pulmonary use. We evaluated Franseen needles with EBUS to assess its utility, safety and ability to provide core biopsy specimens. MATERIALS AND METHODS: Retrospective analysis of our database at the University of Utah of patients undergoing EBUS with a Franseen needle was performed to ascertain the performance characteristics of this needle in the first 100 patients after its implementation. Medical records were also reviewed to identify any immediate procedure-related complications. RESULTS: One hundred seventy locations were sampled in 100 patients. A total of 152 lymph nodes and 18 masses were sampled. Core biopsies, as per pathology report, were seen in 87% of patients. A clinically concordant pathological diagnosis was established in 97% of patients. Diagnostic yield for granulomatous lymphadenopathy was 95.6% (22 of 23). No patient-related adverse events were noted. CONCLUSION: The Franseen needle evaluated in this study can safely procure core tissue samples during EBUS bronchoscopy that are adequate for histopathological diagnosis in benign and malignant lesions. Its ability to provide adequate tissue in patients with granulomatous inflammation is encouraging.
