Curriculum Content and Evaluation of Resident Competency in Anatomic Pathology

A Proposal

Association of Directors of Anatomic and Surgical Pathology*

* This document was prepared by an ADASP Working Group composed of James L. Connolly, MD, Christopher D.M. Fletcher, MD, FRCPath, W. Jack Frable, MD, Margaret M. Grimes, MD, Jon H. Ritter, MD (ad hoc member), and Mark R. Wick, MD (chair).

New program requirements promulgated by the Accreditation Council for Graduate Medical Education (ACGME) in the United States necessitate the development of a defined educational program (curriculum) for trainees in all medical specialties, focused on 6 main areas of competency: patient care, medical knowledge, practice-based learning and improvement, interpersonal and communication skills, professionalism, and systems-based practice (see http://www.acgme.org/outcome). In parallel with any such curriculum, training programs are required to develop a detailed set of performance measures to evaluate each resident's competence in these 6 areas. These new requirements are being implemented and, going forward, residency training programs are being inspected and assessed for accreditation according to these guidelines by the various residency review committees (RRCs) in each specialty area.

In anatomic pathology, as in most specialties, the largest and most detailed elements of such a curriculum are devoted to patient care and medical knowledge. Because these elements are taught very largely by anatomic and surgical pathologists, the Association of Directors of Anatomic and Surgical Pathology (ADASP) formed a working group in 2002, the role of which was to develop an "idealized" but flexible curriculum (with associated measures of competence) in anatomic pathology. This document represents the result of these efforts.

The curriculum (and simple guidelines for competency assessment) that follow have been shared with the RRC for Pathology. The RRC has had the opportunity to review this curriculum, and that supervisory body encourages its dissemination, believing that it will serve as a valuable and comprehensive template for many anatomic pathology training programs. In particular, the RRC for Pathology believes that this curriculum should be especially valuable to residency directors as they respond to the recent general competency initiatives of the ACGME (Steven P. Nestler, PhD, and C. Bruce Alexander, MD, personal communication, August 2003). ADASP developed this document with the hope that individual programs will be able to use and modify it to serve local needs, recognizing that there is great heterogeneity in the size, scope, and organization of existing pathology residency programs in the United States. With regard to the aforementioned broader areas of competency, which are more focused on cognitive, personal, behavioral, and intraorganizational skills, the Program Directors in Pathology (PRODS) separately developed guidelines by which these can be assessed, and these guidelines have been posted on the PRODS Web site (http://www.apcprods.org/Library.html). Moreover, updated program requirements regarding the latter aspects of competency also will soon be available in the pathology area of the ACGME Web site (http://www.acgme.org/outcome/comp/compHome.asp).

Competencies in Pathology

The ACGME currently requires that training programs in pathology enable residents to develop competencies in the broad areas described in the following sections.

General Comments on Competencies

Residents must develop competencies in the 6 following areas to the level expected of a new practitioner. Toward this end, each program must define the specific knowledge, skills, and attitudes that are required and provide educational experiences as needed in order for their residents to develop the desired competencies. The program must create and reinforce the concept of lifelong learning.

Patient Care

Residents must demonstrate a satisfactory level of diagnostic competence and the ability to provide appropriate and effective consultation in the context of pathology services.

Medical Knowledge

Residents must demonstrate knowledge about established and evolving biomedical, clinical, and cognate (eg, epidemiologic and social-behavioral) sciences and the application of this knowledge to pathology.

Practice-Based Learning and Improvement

Residents must be able to demonstrate the ability to investigate and evaluate their diagnostic and consultative practices, appraise and assimilate scientific evidence, and improve their patient care practices.

Interpersonal and Communication Skills

Residents must be able to demonstrate interpersonal and communication skills that result in effective information exchange and teaming with other health care providers, patients, and patients' families.

Professionalism

Residents must demonstrate a commitment to carrying out professional responsibilities, adherence to ethical principles, and sensitivity to a diverse patient population.

Systems-Based Practice

Residents must demonstrate an awareness of and responsiveness to the larger context and system of health care and the ability to call on system resources to provide pathology services that are of optimal value.

Although principal responsibility for ensuring this process lies with pathology residency program directors and their department chairs, the ADASP seeks to set standards in anatomic pathology that are applicable principally to the area of patient care (and, to a lesser extent, medical knowledge).

Observations on Competencies in Pathology

The curriculum and associated competencies proposed by the ADASP relate principally to "core" (nonelective) training in anatomic pathology. The ADASP does not seek, at the current time, to define competencies for advanced training in specific subspecialty areas with dedicated fellowships and board examinations (eg, hematopathology, dermatopathology).

Because individual residency programs show marked variation in the sequence and duration of individual rotations, the ADASP believes that it is not practicable to define competencies that are specific for year 1 or year 2 of training. Instead, certain competencies are simply described as "more advanced." The ADASP also believes that it is neither realistic nor desirable to specify certain diagnoses or defined numbers of cases of a given type as elements of competency. All ACGME-accredited training programs are already required to provide a caseload that is both high enough and varied enough to ensure broad training. Undue emphasis on specific diagnoses or number of cases underestimates the continuous and experiential nature of learning anatomic pathology.

In defining competencies in anatomic pathology, the ADASP seeks to delineate specific and critical areas in the training process, without attempting to provide excessive detail or complexity. Attempts to microdefine competencies could hinder programmatic individuality, would likely be impractical, and would render assessment of competency more difficult. In this regard, it is also unfeasible to define specific standards in any quantitative way, and, therefore, the ADASP endorses the style of competency assessment favored by ACGME (using descriptors such as novice-level, competent, and expert-level).

The ADASP recommends that each of the competencies be assessed as follows: novice, advanced beginner, competent, proficient, expert.

Oral Squamous Cell Carcinoma: Histologic Risk Assessment, but Not Margin Status, Is Strongly Predictive of Local Disease-free and Overall Survival

Brandwein-Gensler M, Teixeira MS, Lewis CM et al


To analyze the impact of resection margin status and histologic prognosticators on local recurrence (LR) and overall survival (OS) for patients with oral squamous cell carcinoma (OSCC). This study was both retrospective and prospective in design. Cohort 1 refers to the entire group of 292 patients with OSCC. The slides from the earliest resection specimens from Cohort 1 were examined in an exploratory manner for multiple parameters. Cohort 2 refers to a subset of 203 patients, who did not receive any neoadjuvant therapy and had outcome data. Cohort 3 represents a subset of Cohort 2 (n = 168) wherein the histologic resection margin status could be reconfirmed. Cohort 4 refers a subset of 85 patients with tongue/floor of mouth tumors. Margin status was designated as follows: group 1, clearance of >/=5 mm with intraoperative analysis, no need for supplemental margins (n = 46); group 2, initial margins were measured as <5 mm during intraoperative frozen section; supplemental resection margins were negative on final pathology (n = 73); group 3, the final pathology revealed resection margins <5 mm (n = 30); group 4, the final pathology revealed frankly positive resection margins (n = 19). The endpoints of LR and OS were queried with respect to T stage, tumor site, margin status, and numerous histologic variables, by Cox regression and Kaplan-Meier survival analyses. Tumor stage (T) was significantly associated with LR (P = 0.028). Kaplan-Meier analysis for stage and for intraoral site was significantly associated with LR for T4 tumors. The increased likelihood of LR was higher for T4 OSCC of the buccal mucosa (75%), sinopalate (50%), and gingiva (100%) compared with mobile tongue (27%), and oropharynx (13%) (P = 0.013). Margin status was not associated with LR or OS (Cohort 3). This was so when all tumors were grouped together and when separate analyses were performed by tumor stage and oral subsite. No significance was demonstrated when margin status was examined for patients with similar treatment (surgery alone or surgery with adjuvant RT). However, the administration of adjuvant RT did significantly increase local disease-free survival (P = 0.0027 and P = 0.001 for T1 and T2 SCC, respectively). On exploratory analyses of histologic parameters, worst pattern of invasion was significantly associated with LR (P = 0.015) and OS (P < 0.001). Perineural invasion involving large nerves (>1 mm) was associated with LR (P = 0.005) and OS (P = 0.039). Limited lymphocytic response was also significantly associated with LR (P = 0.005) and OS (P = 0.001). When used as covariates in a multivariate Cox regression model, worst pattern of invasion, perineural invasion, and lymphocytic response were significant and independent predictors of both LR and OS, even when adjusting for margin status. Thus, these factors were used to generate our risk assessment. Authors risk assessment classified patients into low-, intermediate-, or high-risk groups, with respect to LR (P = 0.0004) and OS (P < 0.0001). This classification retained significance when examining patients with uniform treatment. In separate analyses for each risk group, authors found that administration of adjuvant radiation therapy is associated with increased local disease-free survival for high-risk patients only (P = 0.0296) but not low-risk or intermediate-risk patients. Resection margin status alone is not an independent predictor of LR and cannot be the sole variable in the decision-making process regarding adjuvant radiation therapy. Authors suggest that the recommendation for adjuvant radiation therapy be based on, not only traditional factors (inadequate margin, perineural invasion, bone invasion) but also histologic risk assessment. If clinicians want to avoid the debilitation of adjuvant radiation therapy, then a 5-mm margin standard may not be effective in the presence of high-risk score.

Early Vulvar Squamous Neoplasia: Advances in Classification, Diagnosis, and Differential Diagnosis

Medeiros, Fabiola; Nascimento, Alessandra F; Crum, Christopher P

The recognition and classification of preinvasive vulvar neoplasia are complicated by the facts that (a) their respective carcinomas have a diverse (human papillomavirus [HPV]- and non-HPV-related) pathogenesis; (b) not all vulvar squamous carcinomas are associated with precursors with strictly defined morphologic features; (c) many carcinomas have epithelial changes that are abnormal but lack sufficient nuclear atypia to warrant classification as an intraepithelial neoplasm; and (d) even lesions associated with a common etiologic agent (HPV) present a diverse morphologic spectrum. In this review, five categories of early vulvar neoplasia are defined, based on the available literature, into (a) low-grade lesions with minimal cancer risk, (b) high-grade lesions associated with HPV, (c) high-grade lesions associated with other etiologies, (d) squamous atypias defined by abnormalities in differentiation rather than abnormalities in nuclear morphology, and (d) early carcinomas that do not exhibit conspicuous stromal invasion. The first three groups are arranged into low- and high-grade intraepithelial lesions, the fourth into intraepithelial atypias that bear careful follow-up and attention to the co-existing squamous mucosa, and the fifth into a category that, depending on the degree of cell differentiation, may warrant local excision or lymph node dissection. Recognition of these five categories is germane to proper management of women with squamous lesions of the vulva.

Virtual Microscopy

Applications in Diagnostic Pathology

EDITORIAL

M Lundin, J Lundin and J Isola

In the December 2004 issue of the Journal of Clinical Pathology, authors describe an atlas of breast histopathology, implemented with web based virtual microscopy. The article highlights the advantages of virtual microscopy compared with traditional methods for producing educational material in histopathology. The described slide scanning and viewing technology will also enable novel applications, such as large scale quality assurance programmes, virtual slide seminars, and virtual slides as supplements to scientific publications. In this editorial, authors describe current and future applications of virtual microscopy, and we discuss how the technology could be refined to allow even further applications in diagnostic pathology.

"Virtual slides archived on a network server can be individually controlled and viewed by a large number of simultaneous users"

The terms "virtual microscopy" and "telepathology" are often confused. Dynamic telepathology refers to remote robotic operation of a motorised microscope and real time transmission of the video image. In contrast, virtual microscopy is a form of static telepathology, where digital imaging technology is used to digitise, store, and view slides. A digital representation of an entire slide at the resolution of a high magnification objective is designated a "virtual slide". The application spectrum of dynamic telepathology is limited by its "live" nature and single user control, whereas virtual slides archived on a network server can be individually controlled and viewed by a large number of simultaneous users. This is the key to a wide range of potential applications of virtual microscopy, from production of educational material to integration into the hospital patient record system.


APPLICATIONS
Education
Educational material in pathology teaching has traditionally been based on printed micrographs and projection slides, and buyers of modern textbooks now often receive a supplemental CD with digital images. Whether digital or not, an ordinary micrograph is limited to a preselected area and magnification. In contrast, virtual microscopy enables viewing of any part of a specimen at any magnification. With annotations, selected important areas in a virtual slide can be pinpointed, corresponding to micrographs in printed textbooks. In addition, for pathologists in training, virtual slide atlases provide a feasible way to view collections of very rare diagnostic entities. "Quiz modes" and other interactive functions, such as grading tutorials, are new and interesting educational tools.

Research
By providing virtual slides as supplements to research articles in scientific journals, results can be documented and thus verified by other researchers in a way not currently possible with ordinary printed micrographs. In molecular pathology research, studies using tissue microarrays could provide the entire study material viewable as supplemental web based virtual slides. Readers of case studies and studies describing new or rare histopathological entities will benefit from the possibility of viewing the virtual slides of the lesions described. Thus, virtual microscopy responds to increasing demands on openness and transparency in scientific reporting. Standard platforms for publishing virtual slides online, ensuring future access, would be valuable for authors, journals, and the readers.

Live presentations

Didactic live presentations on diagnostic pathology are currently largely dependent on the use of conventional digital images embedded in PowerPoint presentations. With virtual microscopy, the presenter, with the use of a mouse, can navigate to any area within a slide on the projector screen and seamlessly change magnification. Interesting areas that have been annotated beforehand can instantly be displayed. The visual experience of the audience thus resembles that of viewing a glass slide using a multiheaded microscope or a microscope connected to a projector, but the number of participants can be much larger. When it comes to clinical meetings or slide seminars, it is also possible for the audience to view the virtual slides before the presentation. It is easy to foresee that this will be an integral part of future pathology congresses, where the paid registration fee not only includes the congress abstracts, but also opens access to the congress website, containing virtual slides of the cases to be presented in the lectures.

Multiple copies of microscope slides

Applications requiring multiple copies of microscope slides are ideally suited to virtual microscopy. Interlaboratory comparisons of histopathological diagnoses have been conducted by preparing replicate sets of microscope glass slides and distributing them to the participating pathologists. When the specimen sample is small, such as a needle biopsy, this is not possible, and for cytological specimens there is often only a single diagnostic slide. Virtual microscopy allows each participant to view exactly the same tissue section, thus facilitating quality control programmes, even at a nationwide or international scale. Virtual microscopy could also be used for pathology board certification examinations, which are difficult to arrange if identical specimen sets are considered necessary.


ISSUES INVOLVED

A common feature of the applications discussed thus far is that virtual microscopy introduces a new level of functionality, not previously possible to accomplish. However, for further applications in diagnostic pathology, important issues to consider include image quality, slide navigation and viewing speed, depth of focus, storage costs, and scanning time.

The atlas presented in this issue of JCP shows that slides can be digitised with an image quality that would satisfy most pathologists. However, the image quality seen by the end user is ultimately determined by the resolution and size of the computer screen. The quality of monitors has improved rapidly, and one of the main improvements in the next generation of computer operating systems will be a shift from low resolution systems towards high resolution screen standards. With a large monitor, more image information can then be conveyed through a screen than is seen in one high power field through the oculars. Because each monitor and graphics adapter displays the image slightly differently, the possibility of directly adjusting visual properties such as brightness and contrast of the virtual slides is important, especially because every pathologist has his own personal way of fine-tuning the settings in the microscope.

"The depth of field in a virtual slide can be extended by capturing and layering multiple focal planes, and these can also be digitally merged"

Navigation by stage movement becomes almost a reflex action in pathologists, but getting accustomed to navigating a virtual slide with the mouse in combination with a overview window offers great advantages. Within a standard intranet of a pathology department, the viewing system described in this issue corresponds well to conventional microscopy in terms of viewing speed. There is no noticeable time delay when zooming in and out (switching objectives), and the specimen is automatically in focus. However, in a microscope, it is possible to adjust the focus continually by moving the zone of sharpness up and down the optical axis. This is important, because with a high quality objective, the depth of field is smaller than the thickness of most histological specimens. The depth of field in a virtual slide can be extended by capturing and layering multiple focal planes, and these can also be digitally merged. This technology will be important especially for viewing cytological specimens, which represent entire cells, unlike 25 m thick tissue sections.

The resolution and image quality of the atlas slides described in this issue of JCP were adjusted according to feedback from pathologists. This generated file sizes that only a few years ago would have resulted in massive storage costs. As a result of increasing capacity and falling prices of fast storage systems this is no longer a crucial issue, even if a department scanned every diagnostic slide produced in the laboratory. However, scanning with a x40 microscope objective was found necessary, leading to relatively long scanning times. Slide scanning with a x10 or x20 objective would be much faster, but the resulting image quality is clearly compromised. A promising technique to speed up scanning is parallel imaging using array microscope technology.

Most of the discussed problems have thus already been solved, and it seems clear that all technical obstacles will eventually be solved. As discussed, storage costs are already manageable, and obtaining the scanning equipment is a one-time cost. But although economically feasible, high quality digitisation of slides with current scanning systems is time consuming, so that its application in everyday diagnostic pathology cannot yet be recommended. Furthermore, the need for routine scanning of all diagnostic slides is still unclear. However, there is no doubt that a scanned copy of a slide would be valuable, because previous and current biopsies from the same patient could quickly be viewed, and slides would be readily available for meetings and consultations. It is likely that scanning of slides in pathology departments will begin with only the "interesting" slides being scanned as part of clinical meetings, consultations, and slide seminars. Regardless of whether all or only a part of all slides are scanned, it will be important that virtual slides are properly archived, together with complementary data, such as meeting protocols or seminar handouts, because these will constitute a valuable source of educational and reference material. There will gradually be a need to integrate the virtual slides into the hospital patient record system, thus creating a system corresponding to the highly successful picture archiving and communication systems in radiology departments.


THE FINAL OBSTACLE

The perception of an image also involves a non-conscious part in the sequence leading to diagnosis. Whether a pathologist used to conventional glass slides can get the same perception from a computer screen remains to be seen when all technical aspects are solved. Perhaps future pathologists, who will get a considerable part of their training from virtual slides, will develop a different kind of "feeling" for screen viewing. Perhaps there might be differences within the slides, some being better visualised on a computer screen, some using a microscope.

"The feedback that we have received from pathologists shows that virtual microscopy should currently be regarded as a useful complement to conventional microscopy"

Already today virtual microscopy has a high potential for various tasks in pathology education, in clinical meeting activity, and in quality control. The feedback that authorse have received from pathologists shows that virtual microscopy should currently be regarded as a useful complement to conventional microscopy. The digital revolution in pathology will not be as swift and radical as in radiology. Instead, it will take place in a stepwise fashion, the pace and applications involved dictated by the needs of the pathologists, and paralleled by advances in microscope slide scanning and computer monitor technology.
