The UICC Telepathology Consultation Center. International Union Against Cancer. A global approach to improving consultation for pathologists in cancer diagnosis.

BACKGROUND: The morphologic diagnosis of tumor specimens with precise tumor typing, staging, and grading remains the basis of almost all cancer treatments. Thus, in each tumor case, a histologic diagnosis of the highest quality should be the physician's priority. In approximately 10-20% of tumor cases, diagnostic uncertainty remains to some degree, requiring a second opinion in determining the biologic behavior, the histogenesis, the grade of dedifferentiation, or any other parameter. Facilitating the communication between pathologists and the exchange of cases, telepathology gains more and more importance. To benefit from this technical development, the International Union Against Cancer (UICC) has decided to establish a Telepathology Consultation Center (UICC-TPCC) for interested pathologists around the world. METHODS: The communication and exchange of histologic images works via the Internet. To ensure constant documentation, a case-based data base and image archive is used. Special TPCC software handles all requests to the TPCC and controls the interaction among requesting pathologists, TPCC, and UICC experts (transferring, reading, answering, logging, storing, etc.). All necessary data for controlling the telepathology service are stored in a customized SQL data base. The necessary equipment for the requesting pathologist is a personal computer; a digital or television camera/frame grabber, which is attached to a microscope; and access to the Internet. The requesting party contacts the TPCC's World Wide Web server and uploads the images and the clinical data of their case. To ensure uninterrupted functioning, the hardware will be part of a high-level communication center, which is connected via ATM (asynchronous transfer mode, 155 megabits per second) to the Internet. RESULTS: The UICC has decided to establish the TPCC at the Institute of Pathology at the Charité, Humboldt-University, Berlin, Germany. The TPCC will not make the diagnoses itself but will involve an affiliated specialized expert pathologist. He or she will be on the panel of UICC experts who will constitute the "diagnostic backbone" of the TPCC. The center will function as follows: If a pathologist anywhere on the globe is confronted with the diagnosis of a difficult tumor case, he takes digitized histologic images (5-40 in number) and sends them along with sufficient clinical data to the server of the UICC-TPCC, asking for a second opinion. The center checks the case and transfers it to one of the UICC experts. This expert makes his or her diagnostic suggestion, which is then transferred back to the requesting pathologist via the UICC-TPCC. CONCLUSIONS: The UICC-TPCC will be able to provide rapid and inexpensive diagnostic aid to pathologists all over the world, offering the possibility of a second opinion in accordance with the UICC-TNM and World Health Organization (WHO) standards. During the first and second year, the UICC-TPCC will be financed by sponsors. Telepathology makes the distribution of new developments of diagnostic standards, e.g., of the TNM system, WHO terminology, new tumor classifications, and updated information on actual technologies, globally accessible in a direct and rapid way. It also enables a high quality of education and teaching.

Inter-observer variation between general and specialist gastrointestinal pathologists when grading dysplasia in ulcerative colitis.

Histological dysplasia is the cornerstone of colorectal cancer surveillance in ulcerative colitis (UC). Recently, pathologists have received unfavourable media attention concerning other cancer screening programmes. The aim of this study was to determine whether colonic biopsy specimens should be examined by gastrointestinal pathologists as opposed to generalists, by examining inter-observer variation between the two groups. Fifty-one coded slides showing varying degrees of dysplasia were mailed to seven gastrointestinal and six general histopathologists. Pathologists allocated each biopsy into one of four categories without the benefit of a clinical history or an opportunity to use the 'indefinite' category that is included in the Riddell classification. The responses were analysed using kappa statistics. The overall kappa statistic for gastrointestinal pathologists was 0.30 [95% confidence interval (CI)=0.26-0.34] and for general pathologists 0.28 (95% CI=0.23-0.32). Agreement was best for high-grade dysplasia (kappa of 0.54 and 0.61 for GI and general pathologists, respectively). There was total concordance of the 13 pathologists in only four of the 51 slides (7.8%) (95% CI=0.4-15.2%). It is concluded from these results that gastrointestinal pathologists are no better than generalists when grading dysplasia in UC and that agreement is poor in both groups. There is therefore no evidence that there would be any benefit in having specialist histopathology centres concentrating specifically on the interpretation of all surveillance colonoscopy biopsies from around the UK. It must be made clear to the public that surveillance and screening programmes carry a significant rate of histological error and that perfection cannot be expected or achieved with present methods.

Comparison of specimen adequacy in fine-needle aspiration biopsies performed by surgeons and pathologists.

BACKGROUND: Fine-needle aspiration biopsy (FNAB) may yield different results depending on its operator. We compared the proportions of unsatisfactory aspirates obtained by pathologists vs. surgeons. METHODS: In a retrospective review, all FNAB reports and slides performed between March 2002 and February 2003 were grouped by organ/site and according to whether they were done by a pathologist or a surgeon. The proportions of unsatisfactory aspirates for pathologists and surgeons were compared. RESULTS: Of 692 FNABs, 390 were performed by pathologists at the FNAC clinic and the remainder by surgeons. Overall, 15.5% of aspirates obtained were unsatisfactory (n=107). Of aspirates obtained by surgeons, 29.5% were unsatisfactory, compared to 4.6 % of those obtained by pathologists (P<0.001). Pathologists had significantly lower proportions of unsatisfactory aspirates in all sites. A 33% reduction in the number of lymph node excisional biopsies has been reported subsequent to establishment of the FNAC clinic. CONCLUSIONS: The advantages of a pathologist performing FNAB are that a rapid evaluation can be rendered regarding specimen adequacy and the need for repeating the procedure. In addition, pathologists can direct the distribution of aspirated material for other tests such as culture study, flow cytometry and electron microscopy, as indicated by preliminary evaluation of the smears. These factors significantly lower the proportions of unsatisfactory specimens and improve the diagnostic accuracy of FNAB technique.

Clinical pathologist in Korea--training program and its roles in laboratories.

A rapid development of practice of laboratory medicine in Korea owes its success to the clinical pathologists (CP), who have played a role of a pathfinder for laboratories. The Korean CP postgraduate education (residency) program is unique in that it is exclusively for laboratory medicine. The training program for clinical pathologists includes diagnostic hematology, diagnostic immunology, clinical microbiology, clinical chemistry, blood bank, diagnostic genetics, informatics and laboratory management. The program has produced a strong group of about 600 laboratory physicians, officially clinical pathologists since 1963. Most of Korean clinical pathologists work as laboratory directors, directors of university hospital laboratories or teaching faculty members in medical schools. The roles of clinical pathologists are laboratory management, interpretation of laboratory test results, clinical consulting services to clinicians and patients, ordering secondary tests after reviews of requested test results and utilization management. The clinical pathologists have developed clinical laboratories to be a main contributor for improved medical practice. During the last 40 years under the turbulent healthcare system, clinical pathologists have significantly contributed to safeguard the laboratory interests. The education program and the role of clinical pathologists are described.

Interinstitutional comparison of frozen section turnaround time. A College of American Pathologists Q-Probes study of 32868 frozen sections in 700 hospitals.

OBJECTIVES: To study the intraoperative turnaround time for performing a frozen section (FS) and to examine pathology practice variables that influence it. DESIGN: Over a 4-month period in 1995, participants in the College of American Pathologists Q-Probes laboratory quality improvement program prospectively collected data on up to 30 FS procedures performed on elective inpatient surgical cases and completed questionnaires profiling their FS practice characteristics. SETTING: Surgical pathology laboratories serving private and public hospitals. PARTICIPANTS: Seven hundred institutions located in North America (667), Australia (12), New Zealand (1), the United Kingdom (3), Hong Kong (1), Mexico (1), and Norway (1). MAIN OUTCOME MEASURES: The 90% FS block completion time defined as the time interval, in minutes, within which the fastest 90% of all FS blocks were completed, measured from the time pathologists received FS specimens to the time they communicated FS results to the surgeon. RESULTS: Participants submitted data on 32868 FS blocks. Ninety percent of FS procedures were completed within 20 minutes. Frozen section turnaround times exceeding 20 minutes, termed outlier turnaround times, were more likely to occur when more than one pathologist participated in the FS diagnosis, pathology residents and medical students participated in the FS procedure, the pathologist had to retrieve and review previous case material during the FS procedure, the pathologist simultaneously received additional specimens from other FS cases, the pathologist was unable to reach a final FS diagnosis, and when technical problems occurred during the FS procedure. Seventy percent of all participating hospitals completed 90% of their frozen sections within 20 minutes. The institutional 90% completion times were shorter for hospitals containing 300 or fewer occupied beds than for those containing more than 300 occupied beds. CONCLUSIONS: The data suggest that 90% of FS block turnaround times can be performed within 20 minutes, measured from the time that pathologists receive FS specimens to the time that pathologists return FS diagnoses to surgeons.

Speech-language pathologists' training and confidence in serving Spanish-English bilingual children.

UNLABELLED: The purpose of the investigation was to determine the level of training and confidence of speech-language pathologists in serving Spanish-English bilingual children. Surveys were completed by 213 speech-language pathologists working in the public schools. Comparisons were made among responses from non-diverse rural, non-diverse urban, and diverse urban areas. Results revealed that approximately one-third of the sample did not receive training in multicultural/multilingual issues as undergraduates or graduate students. Approximately, one-fifth of the sample could not recall whether or not they had received training in this area. Eighteen to 25% of the respondents in the three groups received information through lectures in one or more courses. A larger percentage of speech-language pathologists from non-diverse urban areas received training on specific topics related to multicultural/multilingual topics and participated in a larger number of continuing education activities than speech-language pathologists from diverse urban and non-diverse rural areas. No differences were found among the three groups with regard to their confidence in serving bilingual children. Although speech-language pathologists had some confidence when assessing bilingual children whose primary language was English, and when working with bilingual parents and interpreters, respondents lacked confidence when assessing bilingual children whose primary language was Spanish and when working with parents who do not speak English. Implications for the profession are discussed. LEARNING OUTCOMES: (1) As a result of this activity, the participant will be able to discuss the training speech-language pathologists have received in the area of multilingual/multicultural children. (2) As a result of this activity, the participant will be able to discuss speech-language pathologists' level of confidence when serving bilingual, Hispanic children. (3) As a result of this activity, the participant will be able to articulate the implications of this study for current training programs and the profession.

Accuracy of pathologic interpretation of colorectal polyps by general pathologists in community practice.

BACKGROUND: The histologic features of colorectal polyps often guide colonoscopic surveillance and the need for surgical intervention. Our objective was to evaluate the pathologic interpretation of colorectal polyps by general pathologists in community practice. METHODS: Twenty histologic slides of colorectal polyps were reviewed by 20 randomly selected general pathologists in community practice. There were 5 malignant polyps, 9 adenomas, and 6 miscellaneous polyps. RESULTS: Cancer was correctly identified in 91% of readings and adenoma in 94%. The grade of differentiation of cancer was provided in 55% of readings, and comment regarding whether the resection margin was free of cancer was made by 50% of pathologists. Tubular adenoma was called tubulovillous or villous in 35% of readings, but tubulovillous or villous adenoma was seldom (2%) called tubular. High-grade dysplasia was correctly identified in 47% of 60 readings, was called invasive cancer in 22%, and was missed in 31%. Among miscellaneous polyps, hyperplastic polyp was correctly recognized in 75% of cases, and inflammatory polyp and juvenile polyp each were recognized by 16 of 20 pathologists (80%). Peutz-Jeghers hamartoma was identified by 4 of 20 pathologists (20%), and the polypoid phase of solitary rectal ulcer syndrome was recognized by 2 pathologists (10%). CONCLUSION: Areas of strength with regard to interpretation of colon polyps by general pathologists in community practice included identification of cancer, adenoma, and certain non-neoplastic polyps (e.g., inflammatory and juvenile polyps). Areas of weakness included lack of comment on cancer differentiation and proximity to the resection line, erroneous identification of high-grade dysplasia, and identification of rare lesions. The results of this study suggest areas on which to focus continuing education and continuous quality improvement efforts with regard to polyp interpretation.

Accuracy of gleason grading by practicing pathologists and the impact of education on improving agreement.

The aims of this study were to evaluate the accuracy of Gleason grading for prostatic adenocarcinoma among practicing pathologists in Japan and to determine the influence of education on this accuracy. Using a case-oriented approach, 16 hematoxylin and eosin-;stained glass slides with consensus scores established by 4 urologic pathologists were reviewed by 91 pathologists, divided into 2 groups. In group A, average agreements with consensus scores before and after an educational lecture were 55.7% (n = 17) and 68.4% (n = 25), and average kappa values were 0.43 and 0.67, respectively. Twelve pathologists reviewed slides twice in a different order, with average agreements of 59.5% and 77.6%, and average kappa values of 0.48 and 0.69 before and after the lecture, yielding a statistically significant improvement. In group B, the average agreement before providing an atlas with a tutorial was 61.3% (n = 61), and the kappa value was 0.44. In the second round, the average agreement was 74.5% (n = 39), and the kappa value was 0.68. Among 39 pathologists who reviewed slides twice, the average agreement in the first round was 58.8%, and the kappa value was 0.42. Improvement of both the average agreement and the kappa value were statistically significant. The average improvement in kappa values among participants who reviewed slides twice was 0.22 in group A and 0.27 in group B, a difference that is not statistically significant. Combining both groups, the incidence of concordant scores for 16 cases rose from 58.9% to 75.4%, an average increase of 16.5%. The undergrading of score 5-7 lesions was significantly reduced, from 36.3% to 14.2%. With respect to demographic factors, pathologists signing out more than 5000 cases per year showed a better agreement than those with more than 1000 cases per year (48.9% versus 78.8%; P = 0.031). These results indicate that the general agreement of Gleason scores among practicing pathologists in Japan was comparable with those in the Western countries as reported in the literature. Although this requires further improvement, both the lecture and the printed material had a similar influence on the degree of improvement.

Differences in diagnostic criteria for gastric carcinoma between Japanese and western pathologists.

BACKGROUND: There have been many studies on gastric carcinoma in populations with contrasting cancer risks. We aimed to find out whether the criteria for the histological diagnosis of early gastric carcinoma were comparable in Western countries and Japan. METHODS: Eight pathologists from Japan, North America, and Europe individually reviewed 35 microscope slides: 17 gastric biopsy samples and 18 endoscopic mucosal resections taken from 17 Japanese patients with lesions ranging from early gastric cancer to adenoma, dysplasia, and reactive atypia. The pathologists were given a list of pathological criteria and a form on which they were asked to indicate the criteria on which they based each diagnosis. FINDINGS: For seven slides most Western pathologists diagnosed low-grade adenoma/dysplasia, whereas the Japanese diagnosed definite carcinoma in four slides, suspected carcinoma in one, and adenoma in only two. Of 12 slides with high-grade adenoma/dysplasia according to most Western pathologists the Japanese gave the diagnosis of definite carcinoma in 11 and suspected in one. Of six slides showing high-grade adenoma/dysplasia with suspected carcinoma according to most Western pathologists the Japanese diagnosed definite carcinoma in all. There were no major differences in the diagnoses of three slides showing reactive epithelium and seven slides with clearly invasive carcinoma. When the opinion of the majority of the pathologists was taken as the final diagnosis there was agreement between Western and japanese in 11 of the 35 slides (kappa coefficient 0.15 [95% CI 0.01-0.29]). Presence of invasion was the most important diagnostic criterion for most Western pathologists whereas for the Japanese nuclear features and glandular structures were more important. INTERPRETATION: In Japan, gastric carcinoma is diagnosed on nuclear and structural criteria even when invasion is absent according to the Western viewpoint. This diagnostic practice results in almost no discrepancy between the diagnosis of a superficial biopsy sample and that of the final resection specimen. This may also contribute to the relatively high incidence and good prognosis of gastric carcinoma in Japan when compared with Western countries.

Interobserver variability between general and expert pathologists during the histopathological assessment of large-core needle and open biopsies of non-palpable breast lesions.

The purpose of this study was to assess whether general pathologists are able to make as accurate and reproducible a diagnosis on large-core needle biopsies as on open breast biopsy specimens. A total of 688 patients underwent a stereotactic large-core (14G) needle biopsy and subsequent surgical excision of 718 non-palpable breast lesions. Forty-two pathologists from 10 departments of pathology (generalists) made a diagnosis on both the needle and open biopsy specimens. Afterwards, three pathologists and two radiologists with extensive experience in breast pathology (experts) diagnosed all of the biopsy specimens. The general pathologists made a similar histological diagnosis as the experts in 632 (88%) of the needle biopsies and 649 (90%) of the open biopsy specimens. Accordingly, the interobserver agreement for the diagnosis of large-core needle biopsies between the general and experts pathologists was excellent (kappa 0.83) and not significantly different from the interobserver agreement for the diagnosis of open breast biopsies (kappa 0.86). However, many inconsistencies were observed in the category of borderline lesions: only 24% of the large-core needle biopsies and 43% of the open biopsies with an expert diagnosis of 'borderline' were diagnosed similarly by the general pathologists. Additionally, the risk of benign/malignant inconsistencies between general pathologists and experts was approximately 1 in 55 for both needle and open biopsies.

Interobserver variation in diagnosing coeliac disease. A joint study by Danish and Swedish pathologists.

There is an almost 40-fold difference in incidence rates of symptomatic coeliac disease between Denmark and Sweden. In an attempt to explain this difference, the present study focused on the interobserver agreement when pathologists were assessing small intestinal biopsy specimens from children suspected of suffering from coeliac disease. The study was performed on 90 biopsy specimens from 73 children. Most of the biopsies came from children who turned out not to suffer from coeliac disease after a clinical evaluation including small intestinal biopsy. Using the kappa methodology, the interobserver agreement between two Danish pathologists and one Swedish pathologist, all of whom were experienced, was "moderate" to "substantial" or 0.57-0.75. Kappa indices when the pathologists evaluated selected histological elements were in the interval from 0.24 to 0.67. A comparison of a previous routine diagnostic assessment of the 90 biopsies (14 pathologists) with the results of the experienced pathologists in the present study gave kappa indices of from 0.53 to 0.57. The study could prove no major differences in the histopathological assessment of small intestinal biopsy specimens made by Danish and Swedish pathologists. The difference in clinical presentation of coeliac disease in Denmark and Sweden does not relate to differences in the histopathological assessment of small intestinal biopsies.

The impact of pathologist experience on liver transplant biopsy interpretation.

We studied the impact of pathologist experience on liver transplant biopsy interpretation for cases designated 'nonspecific' by pathologists at a nontransplant center. Among 102 consecutive liver transplant biopsies from 92 patients performed at the Foothills Medical Center, 30 liver biopsies from 23 patients were designated 'nonspecific' by the local pathologist. These biopsy slides were independently reviewed by an expert in liver transplant pathology at a major US transplant center. The expert pathologist was given only the information on the original requisition. In seven biopsies from five patients, there was full agreement between the external expert and the local pathologist. In 10 biopsies from six patients, the expert concurred with the initial assessment but emphasized critical negatives such as 'no evidence of rejection or recurrent hepatitis'. A discrepant diagnosis was found in 13 biopsies from 12 patients. In five biopsies from four patients, the revised diagnoses were inaccurate due to insufficient or misleading clinical information on the requisition. In eight biopsies from eight patients, the revised diagnoses were proven to be correct by clinicopathologic correlation. Our study shows that pathology expertise helped to clarify the diagnosis in about 27% of cases, which justifies the cost of obtaining a second opinion in difficult biopsies. Misinterpretation by the expert pathologist in up to 17% of biopsies highlights the importance of direct communication between hepatologist and pathologist in order to achieve a correct diagnosis. Familiarity with those cases with relatively uncommon histology, a diligent search for subtle morphologic changes, and use of standard terminology could improve the quality of liver transplant biopsy interpretation in a nontransplant center.

Histologic grading of breast cancer: linkage of patient outcome with level of pathologist agreement.

In the histologic grading of invasive breast cancer with the Nottingham modification of the Scarff-Bloom-Richardson grading scheme (NSBR), it has been found that when pathologists disagree, they tend not to disagree by much. However, if tumor grade is to be used as an important parameter in making treatment decisions, then even this generally small degree of pathologist variability in assessing grade needs to be correlated with patient outcome. Findings from the Nottingham/Tenovus Primary Breast Cancer Study were used for patient outcome data. Kaplan-Meier survival curves were constructed for NSBR scores grouped according to the level at which pathologists tend to agree in assessing grade, from a reproducibility perspective. For example, if a given tumor were assessed by several pathologists as having either an NSBR score of 5 or 6, then what is the correct score--the intermediate-grade Score 6 assessments or the low-grade Score 5 assessments? By "regrouping" the Nottingham outcome data such that data from patients with Score 5 tumors are grouped with patients having Score 6 tumors (a 5-6 group), then the level in which the pathologists agreed with each other (that the tumor was either score 5 or 6) is better matched with patient outcome. In response to the above example, it was not surprising to find that patients with Score 5-6 tumors had a probability of survival between the established low and intermediate NSBR final combined grades. However, it is the discussion of this approach that highlights that optimal use of grading requires awareness of the level of pathologist agreement and understanding the value of pathologists' reaching consensus in assessments. Also, knowledge of possible clinical decision thresholds can help in providing relevant interpretations of grading results.

The expanding role of pathologists in the diagnosis and management of breast cancer: Worldwide Excellence in Breast Pathology Program.

Pathology is the study of human illness and it involves the morphologic and biologic recognition of abnormalities that are associated with a disease. Breast pathology represents an excellent example of this discipline. By providing diagnostic information and by characterizing the biologic behavior of a breast lesion, a pathologist plays a critical role in a patient's life. Any mistake in this exercise is associated with serious consequences. In addition, there are many unresolved issues in breast pathology, which contribute to our limited understanding of the biology of breast cancer, variability in diagnostic criteria, and significant diversity in breast cancer management and therapy. Furthermore, breast pathology has remained an underrecognized discipline, and its importance in diagnosis and disease management is not fully realized. In order to better serve our patients, particularly medically underserved women and those living in countries with limited resources, we must place emphasis on effectively using the talent and expertise of pathologists around the globe. For example, to provide a cost-effective way to diagnose breast cancer, particularly at advanced stages, pathologists can sample lesions by fine-needle aspiration biopsy (FNAB), stain the resulting smears, and provide an immediate bedside diagnosis. This is a valid contribution; however, this exercise requires the availability of a pathologist with experience in breast cytopathology. Alternatively the pathologist may seek consultations from more experienced pathologists. Developing strategies to better recognize the importance of high-quality breast pathology services and to train qualified and innovative breast pathologists is an ambitious task. The proposed Worldwide Excellence in Breast Pathology Program may provide such an opportunity.

Interobserver reproducibility of Gleason grading of prostatic carcinoma: urologic pathologists.

Gleason grading is now the most widely used grading system for prostatic carcinoma in the United States. However, there are only a few studies of the interobserver reproducibility of this system, and no extensive study of interobserver reproducibility among a large number of experienced urologic pathologists exists. Forty-six needle biopsies containing prostatic carcinoma were assigned Gleason scores by 10 urologic pathologists. The overall weighted kappa coefficient kappa(w) for Gleason score for each of the urologic pathologists compared with each of the remaining urologic pathologists ranged from 0.56 to 0.70, all but one being at least 0.60 (substantial agreement). The overall kappa coefficient kappa for each pathologist compared with the others for Gleason score groups 2-4, 5-6, 7, and 8-10 ranged from 0.47 to 0.64 (moderate-substantial agreement), only one less than 0.50. At least 70% of the urologic pathologists agreed on the Gleason grade group (2-4, 5-6, 7, 8-10) in 38 ("consensus" cases) of the 46 cases. The 8 "nonconsensus" cases included low-grade tumors, tumors with small cribriform proliferations, and tumors whose histology was on the border between Gleason patterns. Interobserver reproducibility of Gleason grading among urologic pathologists is in an acceptable range.

Cooperation between surgical oncologists and pathologists: a key element of multidisciplinary care for patients with cancer.

For patients with cancer it is essential to reach a definite diagnosis, obtain accurate staging and provide appropriate initial treatment if a successful outcome is to be achieved. These fundamental first steps in multidisciplinary care require close cooperation between surgical oncologists and pathologists. The most important aspect of this cooperation is clear and free exchange of information between them. The surgeon should provide the pathologist not only with an adequate tissue sample for examination, but also with clinical details that will assist in establishing a diagnosis. The location and orientation of specimens, and areas of particular concern, should always be indicated. Operative digital photographs may assist this process. The pathologist, in return, should provide the surgeon with a report containing sufficient information to allow an evidence-based management plan to be made for the patient, and to permit an accurate indication of prognosis to be determined. Use of a disease-specific synoptic report format will ensure that potentially important information is not overlooked. When there is diagnostic uncertainty, the pathologist should make this clear, but provide a preferred diagnosis. Further opinions may be helpful. If doubt exists, medico-legal considerations should not encourage a pathologist to issue a report with a diagnosis of malignancy. The pathologist should refrain from making management recommendations, because there may be valid reasons for the surgeon not providing this management. By cooperating fully and communicating freely with each other, surgical oncologists and pathologists can ensure high standards of initial and subsequent care for cancer patients.

Cytologic grading of fine needle aspirates of breast carcinoma by private practice pathologists.

OBJECTIVE: To determine the reproducibility of two clinically proven grading systems for breast carcinoma assessed by private practice pathologists. STUDY DESIGN: Twenty fine needle aspiration (FNA) slides of histologically proven breast carcinoma were submitted to 15 private practice pathologists practicing in 11 separate groups who interpret cytology as part of their daily practice. The pathologists received the same set of slides. They graded the FNAs using the modified Black (MB) (grades 1-3) and simplified Black (SB) (low grade, high grade) grading systems. Specified criteria and guidelines as well as case samples were provided. RESULTS: There was complete agreement among the 15 pathologists on only one case using the MB grading system as compared to five using the SB grading system. In MB, > or = 10 pathologists were in agreement on 14 cases as compared to 19 cases using SB. There were three cases in MB where the grades ranged from 1 to 3. Also noted in MB was the high number of cases graded 2 (intermediate grade). The predominant comment made by the pathologists was the easier, more objective and practical application of the SB. CONCLUSION: High reproducibility in the cytologic grading of FNA of breast carcinoma can be more readily attained among private practice pathologists using the two-tier SB grading system.

Pathologists' roles in clinical utilization management. A financing model for managed care.

In ancillary or laboratory utilization management, the roles of pathologists have not been explored fully in managed care systems. Two possible reasons may account for this: pathologists' potential contributions have not been defined clearly, and effective measurement of and reasonable compensation for the pathologist's contribution remains vague. The responsibilities of pathologists in clinical practice may include clinical pathology and laboratory services (which have long been well-defined and are compensated according to a resource-based relative value system-based coding system), laboratory administration, clinical utilization management, and clinical research. Although laboratory administration services have been compensated with mechanisms such as percentage of total service revenue or fixed salary, the involvement of pathologists seems less today than in the past, owing to increased clinical workload and time constraints in an expanding managed care environment, especially in community hospital settings. The lack of financial incentives or appropriate compensation mechanisms for the services likely accounts for the current situation. Furthermore, the importance of pathologist-driven utilization management in laboratory services lacks recognition among hospital administrators, managed care executives, and pathologists themselves, despite its potential benefits for reducing cost and enhancing quality of care. We propose a financial compensation model for such services and summarize its advantages.
