Tinnirello AA. Rapid on-site evaluation of fine-needle aspiration specimens using cytotechnologist-performed telecytology: Insights and advantages. Cytopathology 2024. [PMID: 39158137 DOI: 10.1111/cyt.13428] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2024] [Revised: 07/10/2024] [Accepted: 07/22/2024] [Indexed: 08/20/2024]
Abstract
With multiple health care centres expanding and implementing remotely controlled technologies, the role of cytopathology laboratories will become crucial in optimizing collection and assessment of small biopsy specimens for diagnosis and personalized treatment. Cytopathology services provide rapid assessments of samples obtained from fine-needle aspirations and occasionally core needle biopsies (analysed by touch imprints). Over the past few decades, the cost barrier for hospitals, especially small ones, to support a cytopathologist or cytotechnologist for rapid on-site evaluation (ROSE) has been reduced by the introduction of computerized microscopes that allow cytopathologists to perform ROSE without being present at the satellite laboratory (i.e. remotely). Utilization of the cytotechnologist's experience in ROSE alongside these technologies made it possible to perform ROSE with telecytology (ROSE-TC), which positively impacts diagnosis and treatment and also lowers the cost of care. The satellite laboratories that successfully implemented ROSE-TC operate with experienced cytotechnologists who, working independently between the cytopathology laboratory and the biopsy suite, prepare the smears and stain the slides on site for the distant cytopathologists, who can evaluate the slides remotely (usually from their office) simply using the facility intranet. This article aims to encourage big and small centres to use senior-level cytotechnologists for both ROSE and ROSE-TC. This article also defines different types of ROSE, explains our institution's approach to ROSE procedures, and outlines some experience-driven considerations for successful ROSE-TC and its future evolution.

Oteri V, Piane S, Cocci E. The use of telecytology for the evaluation of thyroid nodules fine-needle aspiration biopsy specimens: a systematic review. J Endocrinol Invest 2024:10.1007/s40618-024-02378-3. [PMID: 38704449 DOI: 10.1007/s40618-024-02378-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/01/2023] [Accepted: 04/18/2024] [Indexed: 05/06/2024]
Abstract
PURPOSE Fine needle aspiration biopsy (FNAB) is currently the gold standard for diagnosis and treatment of thyroid nodules, but the growing need for anatomic pathology services in small communities is becoming a challenge. Telecytology (TC) is defined as the electronic transmission of cytological digital images, and allows for the collection of samples, primary diagnosis, and other applications without the physical presence of a pathologist. Our aim is to systematically report, summarize, and critically analyze the most up to date applications of TC to thyroid nodules FNAB evaluation. METHODS We performed a systematic literature review by searching PubMed, Embase, and Cochrane Library databases. Only studies published in peer-reviewed scientific journals were included. Data were extracted using the PICO framework and critically analyzed. PRISMA guidelines were applied, and the risk of bias in the included studies was assessed using the ROBINS-I tools. The methodological quality was assessed following GRADE criteria. RESULTS We included 13 observational studies, resulting in a total of 3856 evaluated FNAB specimens. The majority of studies (63.6%) showed an excellent concordance rate of diagnosis via TC and conventional cytology. TC can be used to perform preliminary assessment of samples with a concordance rate ranging from 74 and 100%, showing a significant reduction of the non-diagnostic rate. Image quality was referred to as perfect or nearly perfect in most cases, regardless of telecytology technique. CONCLUSION Telecytology could be a valuable implementation for thyroid FNAB evaluation both for primary diagnosis and preliminary assessment of samples.

J Am Soc Cytopathol 2022; 11:218-225. [PMID: 35469774 DOI: 10.1016/j.jasc.2022.03.001] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2022] [Revised: 02/23/2022] [Accepted: 03/07/2022] [Indexed: 06/14/2023]
Abstract
INTRODUCTION Telecytology offers a suitable solution to the cost and time efficiency questions on rapid onsite evaluation (ROSE). An increasing number of institutions are adopting new telecytology systems to meet the increasing ROSE requests, although there is no agreement on the details of how a telecytology validation study needs to be conducted. We propose a standardized approach for telecytology validation studies that could be done in a variety of practices. MATERIALS AND METHODS Consecutive cases from 6 months prior were chosen to reflect a case mix comparable to real life. A fellow assessed the slides at the ROSE site while 6 cytopathology faculty convened in a conference room with a television screen, and noted the adequacy, diagnostic category, and specific diagnoses. All participants were blinded to the original adequacy assessment and final diagnoses. For each case, evaluation time and the slides counts were noted. RESULTS Fine-needle aspiration specimens from 52 patients were included in the study. Of these, 13 cases were used in the first "test" session. The adequacy concordance rates ranged between 92.3% and 100%, with an overall concordance rate of 94.8%. The diagnostic category concordance rates ranged between 90.3% and 95.5%, with an overall concordance rate of 91.9%. The specific diagnosis concordance rates ranged between 84.6% and 92.9%, with an overall concordance rate of 88.1%. CONCLUSIONS Validation of telecytology requires a standardized approach just like any other new technology. In this study, we propose an efficient and accurate method for cytopathology departments of various case volumes to conduct telecytology validation studies.

Sarode VR. The current practice of telecytology for rapid on-site evaluation (ROSE): Practical considerations and limitations. Semin Diagn Pathol 2022; 39:463-467. [PMID: 35718579 DOI: 10.1053/j.semdp.2022.06.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/25/2022] [Revised: 03/08/2022] [Accepted: 06/09/2022] [Indexed: 11/11/2022]
Abstract
Advances in digital imaging technology and development of high-speed internet has brought a change in ROSE practice from the traditional in-person to remote evaluation. The rapid expansion of image-guided procedures to obtain tissues for diagnosis and ancillary testing has put a huge demand on cytopathologists' time to perform on-site adequacy assessment. The technology of transmitting digital slide images in real-time via the internet from procedure site that can be viewed remotely and provide preliminary diagnosis, has had a huge impact on the practice of ROSE. Telecytology (TC) has increased the efficiency of cytopathologists, by cutting down on travel time to procedure sites and eliminate the long wait time between procedures/needle passes. It also provides the cytopathologist with the flexibility of covering ROSE procedures occurring at several locations simultaneously. The options and design of TC systems are driven by clinical needs, availability of resources and case volume. A buy-in from stakeholders early in the process, infrastructure planning and information technology (IT) support are critical for the successful implementation of TC. Training of staff, validation study and compliance training should be performed according to established guidelines. There are different TC platforms commercially available in the market today, these include static image sharing, real-time video streaming, robotic microscopy and whole slide imaging (WSI). Additionally, low-cost TC system can be built and designed using equipment that are available off-the-shelf. The intent of this review is to highlight the current practices of TC, the pros and cons of each system are discussed.

Abstract
The field of anatomic pathology has been evolving in the last few decades and the advancements have been largely fostered by innovative technology. Immunohistochemistry enabled a paradigm shift in discovery and diagnostic evaluation, followed by booming genomic advancements which allowed for submicroscopic pathologic characterization, and now the field of digital pathology coupled with machine learning and big data acquisition is paving the way to revolutionize the pathology medical domain. Whole slide imaging (WSI) is a disruptive technology where glass slides are digitized to produce on-screen whole slide images. Specifically, in the past decade, there have been significant advances in digital pathology systems that have allowed this technology to promote integration into clinical practice. Whole slide images (WSI), or digital slides, can be viewed and navigated comparable to glass slides on a microscope, as digital files. Whole slide imaging has increased in adoption among pathologists, pathology departments, and scientists for clinical, educational, and research initiatives. Integration of digital pathology systems requires a coordinated effort with numerous stakeholders, not only within the pathology department, but across the entire enterprise. Each pathology department has distinct needs, use cases and blueprints, however the framework components and variables for successful clinical integration can be generalized across any organization seeking to undergo a digital transformation at any scale. This article will review those components and considerations for integrating digital pathology systems into clinical practice.

Selective deployment of dynamic telecytology for rapid evaluation of cytology smears: assessment of workflow processes and role of cytopathology fellows as on-site operators. J Am Soc Cytopathol 2021; 10:577-584.

Abstract
INTRODUCTION The deployment of telecytology (TC) requires a substantial investment of financial and human resources. To offset the high demand for rapid on-site evaluation, we performed a limited deployment of dynamic TC and have detailed the workflow processes and the role of trainees. MATERIALS AND METHODS TC systems were installed in radiology suites with a high volume of cases. Validation was performed using retrospective and prospective cases. Cytotechnologists and cytopathology fellows were the operators of the instrument. TC malignant and benign diagnoses were correlated with the final sign-out diagnoses. RESULTS Of the 120 cases, 50 (41.6%) were fine needle aspirations and 70 (58.3%) were touch imprint smears of core biopsy specimens. The cytotechnologists were the operators for 34 cases (28.3%) and cytology fellows for 86 cases (71.6%). Adequacy concordance with the final diagnosis was 100% and 98.5% in the retrospective and prospective cases, respectively. In the prospective cases, concordance of TC with the final diagnosis of malignancy was 42 of 45 (93.3%), with 2 of 45 (4.4%) discordant and a downgrade rate of 2.7%. For the benign diagnoses, the concordance was 90%. For the malignant diagnoses, the sensitivity of TC was 97.67% (95% confidence interval [CI], 87.71 to 99.94%; specificity, 81.82%; 95% CI, 48.22% to 97.72%). The positive predictive value was 95.45% (95% CI, 85.69% to 98.66%), the negative predictive value was 90.00% (95% CI, 55.98% to 98.45%), and the accuracy was 94.44% (95% CI, 84.61% to 98.84%). CONCLUSIONS TC can be deployed in a limited fashion as an option for cytopathologists to offset the high demand for rapid on-site evaluations. Trainee participation in TC service is important for building confidence and honing their cytology skills.

Abstract
Pathology has benefited from advanced innovation with novel technology to implement a digital solution. Whole slide imaging is a disruptive technology where glass slides are scanned to produce digital images. There have been significant advances in whole slide scanning hardware and software that have allowed for ready access of whole slide images. The digital images, or whole slide images, can be viewed comparable to glass slides in a microscope, as digital files. Whole slide imaging has increased in adoption among pathologists, pathology departments, and scientists for clinical, educational, and research initiatives. Worldwide usage of whole slide imaging has grown significantly. Pathology regulatory organizations (ie, College of American Pathologists) have put forth guidelines for clinical validation, and the US Food and Drug Administration have also approved whole slide imaging for primary diagnosis. This article will review the digital pathology ecosystem and discuss clinical and nonclinical applications of its use.

Abstract
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.

Abstract
Whole slide imaging (WSI) allows generation of large whole slide images and their navigation with zoom in and out like a true virtual microscope. It has become widely used in surgical pathology for many purposes, such as education and training, research activity, teleconsultation, and primary diagnosis. However, in cytopathology, the use of WSI has been lagging behind histology, mainly due to the cytological specimen's characteristics, as groups of cells of different thickness are distributed throughout the slide. To allow the same focusing capability of light microscope, slides have to be scanned at multiple focal planes, at the cost of longer scan times and larger file size. These are the main technical pitfalls of WSI for cytopathology, partly overcome by solutions like liquid-based preparations. Validation studies for the use in primary diagnosis are less numerous and more heterogeneous than in surgical pathology. WSI has been proved effective for training students and successfully used in proficiency testing, allowing the creation of digital cytology atlases. Longer scan times are also a barrier for use in rapid on-site evaluation, but WSI retains its advantages of easy sharing of images for consultation, multiple simultaneous viewing in different locations, the possibility of unlimited annotations and easy integration with medical records. Moreover, digital slides set the laboratory free from reliance on a physical glass slide, with no more concern of fading of stain or slide breakage. Costs are still a problem for small institutions, but WSI can also represent the beginning of a more efficient way of working.

Abstract
BACKGROUND AND AIMS Rapid onsite evaluation of touch imprint cytology (ROSE-TIC) is a simple and rapid method used for the diagnosis of benign and malignant lesions. We evaluated the diagnostic accuracy of ROSE-TIC for advanced intestinal luminal and indeterminate pancreatobiliary lesions during endoscopy. METHODS This is a retrospective descriptive study of patients who underwent endoscopy or ERCP between January 1, 2014 and December 31, 2016. It included patients who were referred for the treatment of intestinal luminal lesions or evaluation of indeterminate pancreatobiliary lesions. The slides were prepared by gently touching the specimen onto a glass slide and were examined under the microscope. The main outcome measure was to determine the diagnostic accuracy of ROSE-TIC by comparing the onsite cytology findings with the corresponding off-site histologic diagnosis. RESULTS All 222 patients (106 pancreatobiliary and 116 GI lesions) had a prior benign diagnosis of intestinal luminal lesions or indeterminate diagnosis of pancreatobiliary lesions. The overall sensitivity, specificity, positive predictive value, negative predictive value, and diagnostic accuracy of ROSE-TIC were 97%, 85%, 83%, 97.2%, and 90%, respectively. The accuracy varied with the site of the biopsy sample. The accuracy was lowest for upper GI tract, where it was 85.2% but was 95% for lower GI tract lesions. CONCLUSIONS By establishing a rapid onsite diagnosis, ROSE-TIC expedites decision-making on patient management. Prospective studies are needed to confirm these preliminary findings.

Abstract
Telemedicine uses telecommunications technology as a tool to deliver health care to populations with limited access to care. Telemedicine has been tested in multiple clinical settings, demonstrating at least equivalency to in-person care and high levels of patient and health professional satisfaction. Teleoncology has been demonstrated to improve access to care and decrease health care costs. Teleconsultations may take place in a synchronous, asynchronous, or blended format. Examples of successful teleoncology applications include cancer telegenetics, bundling of cancer-related teleapplications, remote chemotherapy supervision, symptom management, survivorship care, palliative care, and approaches to increase access to cancer clinical trials. Telepathology is critical to cancer care and may be accomplished synchronously and asynchronously for both cytology and tissue diagnoses. Mobile applications support symptom management, lifestyle modification, and medication adherence as a tool for home-based care. Telemedicine can support the oncologist with access to interactive tele-education. Teleoncology practice should maintain in-person professional standards, including documentation integrated into the patient's electronic health record. Telemedicine training is essential to facilitate rapport, maximize engagement, and conduct an accurate virtual exam. With the appropriate attachments, the only limitation to the virtual exam is palpation. The national telehealth resource centers can provide interested clinicians with the latest information on telemedicine reimbursement, parity, and practice. To experience the gains of teleoncology, appropriate training, education, as well as paying close attention to gaps, such as those inherent in the digital divide, are essential.

Abstract
International telecytology can improve patient care by increasing access to regional and international expertise in cytopathology. The majority of international telecytology studies published to date have been based on static telepathology platforms. Overall concordance rates for these studies ranged from 71% to 93%. This is comparable to the concordance rates published for other studies comparing diagnoses made by digital still images to reference glass slides, which vary from 80% to 95%. Static telepathology systems are relatively cheap and easy to use, and have the potential to increase access to international experts in developing countries with limited resources. In contrast, resource-rich academic and private medical centers can use whole slide digital imaging (WSI) for telecytology consultation, though few studies have been published addressing this topic. International telepathology consultation services with digital whole slide image capabilities have been established at several academic medical centers including the University of Pittsburgh Medical Center (UPMC) and the University of California at Los Angeles (UCLA), through the UCLA Center for Telepathology and Digital Pathology. In a small series of 20 telecytology cases submitted to UCLA from 2014 to 2017 (10 gynecologic and 10 fine needle aspiration cases), a meaningful diagnosis was rendered for 100% of cases, with 100% concordance between the submitting institution, versus consultation diagnosis provided by UCLA. These limited results are promising, and in the future both WSI and static telecytology consultation may have a place serving clinical needs in different practice settings.
