Factors associated with loss to follow up after abnormal cervical cancer screening in pregnancy.

OBJECTIVE: To assess risk factors associated with loss to follow up in patients referred for colposcopy after abnormal cervical cytology during pregnancy in a Southern safety net hospital population. METHODS: An urban colposcopy center was queried for patients referred for follow up of abnormal cervical cytology during pregnancy and the postpartum period. Patients were identified through a standardized referral code in the electronic medical record. Multivariable logistic regression was used to compare patient characteristics between those who followed up for colposcopy and those lost to follow up. Independent risk factors assessed included age, parity, race, insurance, HIV status, history of mental illness, BMI, gestational age and trimester at screening, cytology at colposcopy referral, interval days until colposcopy, and biopsy histology. RESULTS: 1063 patients were identified, with 40.8% of patients who completed referred colposcopy. Patient characteristics predictive for colposcopy follow up included: maternal age at referral cervical cytology >30 years (1.67; 1.27-2.20; < 0.003), gestational age < 18 weeks at abnormal cervical cytology (1.57; 1.23-2.01; <0.0002), maternal race non-African American (2.20; 1.32-3.65; <0.0024) and with high grade cervical cytology (2.42; 1.81-3.24; <0.0001). CONCLUSION: In this population, inadequate follow up for abnormal cervical cytology during pregnancy is prominent, especially among those with younger maternal age, African American (AA) race, cervical cytology completed at later gestational ages of pregnancy, and low-grade initial cytology. Higher no-show rate among AA patients supports well-documented health disparities and need for further investigation and protocols to identify those at risk for loss to follow up.

College of American Pathologists Cancer Protocols: From Optimizing Cancer Patient Care to Facilitating Interoperable Reporting and Downstream Data Use.

The College of American Pathologists Cancer Protocols have offered guidance to pathologists for standard cancer pathology reporting for more than 35 years. The adoption of computer readable versions of these protocols by electronic health record and laboratory information system (LIS) vendors has provided a mechanism for pathologists to report within their LIS workflow, in addition to enabling standardized structured data capture and reporting to downstream consumers of these data such as the cancer surveillance community. This paper reviews the history of the Cancer Protocols and electronic Cancer Checklists, outlines the current use of these critically important cancer case reporting tools, and examines future directions, including plans to help improve the integration of the Cancer Protocols into clinical, public health, research, and other workflows.

Preanalytics and Precision Pathology: Pathology Practices to Ensure Molecular Integrity of Cancer Patient Biospecimens for Precision Medicine.

Biospecimens acquired during routine medical practice are the primary sources of molecular information about patients and their diseases that underlies precision medicine and translational research. In cancer care, molecular analysis of biospecimens is especially common because it often determines treatment choices and may be used to monitor therapy in real time. However, patient specimens are collected, handled, and processed according to routine clinical procedures during which they are subjected to factors that may alter their molecular quality and composition. Such artefactual alteration may skew data from molecular analyses, render analysis data uninterpretable, or even preclude analysis altogether if the integrity of a specimen is severely compromised. As a result, patient care and safety may be affected, and medical research dependent on patient samples may be compromised. Despite these issues, there is currently no requirement to control or record preanalytical variables in clinical practice with the single exception of breast cancer tissue handled according to the guideline jointly developed by the American Society of Clinical Oncology and College of American Pathologists (CAP) and enforced through the CAP Laboratory Accreditation Program. Recognizing the importance of molecular data derived from patient specimens, the CAP Personalized Healthcare Committee established the Preanalytics for Precision Medicine Project Team to develop a basic set of evidence-based recommendations for key preanalytics for tissue and blood specimens. If used for biospecimens from patients, these preanalytical recommendations would ensure the fitness of those specimens for molecular analysis and help to assure the quality and reliability of the analysis data.

Freeing the data from cytology databases in order to improve the quality of cytology.

INTRODUCTION: To review how changes in data storage and analysis can impact quality and quality assessment in cytology. METHODS: Review of the literature. RESULTS: All quality assessment is dependent on the data available for review and the methods available for evaluation. Current laboratory information systems (LISs) incorporate both a relational or hierarchical database and built in methods to analyze current quality assessment standards. In contrast, most information systems outside of medicine are separating data storage from analysis, allowing increasingly more sophisticated forms of evaluation. CONCLUSION: There is an opportunity for improvement in cytology by improving the way data can be extracted and analyzed from the cytology LIS.

Recent Developments in Surgical Pathology of the Uterine Corpus.

There have been several updates recently on the classification of uterine tumors. Endometrial carcinomas have traditionally been divided into 2 types, but some are difficult to classify and do not fit readily into either of the currently recognized categories. The Cancer Genome Atlas Research Network has recently defined 4 new categories of endometrial cancer on the basis of mutational spectra, copy number alteration, and microsatellite instability, which might provide independent prognostic information beyond established risk factors. The Society of Gynecologic Oncology, moreover, now recommends systematic screening of every patient with endometrial cancer for Lynch syndrome. The new definition of high-grade endometrial stromal sarcoma disregards the number of mitotic figures as a primary diagnostic criterion and instead specifies moderate atypia still resembling stromal origin but lacking the pleomorphism of undifferentiated uterine sarcoma; these tumors also harbor a JAZF1-SUZ12 gene rearrangement. Mitotic count, atypia, and coagulative necrosis are the main histologic criteria that define leiomyosarcoma. Determining the type of necrosis can be very challenging in patients receiving various treatment modalities for symptomatic fibroids before myomectomy, since key histologic features of ischemic-type necrosis are often absent. Ancillary stains including p16, p53, MIB-1, trichrome, and reticulin may be helpful in tumors harboring necrosis that is difficult to classify. Minimally invasive gynecologic surgeries have introduced histologic artifacts that complicate the diagnosis. It is essential to recognize these as procedure-related artifacts to avoid upstaging tumors and triggering unnecessary adjuvant treatment.

Ordo ab Chao: framework for an integrated disease report.

CONTEXT: The volume of information that must be assimilated to appropriately manage patients with complex or chronic disease can make this task difficult because of the number of data points, their variable temporal availability, and the fact that they may reside in different systems or even institutions. OBJECTIVE .- To outline a framework for building an integrated disease report (IDR) that takes advantage of the capabilities of electronic reporting to create a single, succinct, interpretative report comprising all disease pertinent data. DESIGN: Disease pertinent data of an IDR include pathology results, laboratory and radiology data, pathologic correlations, risk profiles, and therapeutic implications. We used cancer herein as a representative process for proposing what is, to our knowledge, the first example of standardized guidelines for such a report. The IDR was defined as a modular, dynamic, electronic summary of the most current state of a patient in regard to a particular illness such as lung cancer or diabetes, which includes all information relevant for patient management. RESULTS: We propose the following 11 core data concepts that an IDR should include: patient identification; patient demographics; disease, diagnosis, and prognosis; tumor board dispositions and decisions; graphic timeline; preresection workup and therapy; resection workup; interpretative comment summarizing pertinent findings; biobanking data; postresection workup; and disease and patient status at follow-up. CONCLUSIONS: A well-executed IDR should improve patient care and efficiency for health care team members. It would demonstrate the added value of pathology interpretation and likely contribute to a reduction in errors and improved patient safety by decreasing the risk that important data will be overlooked.

Cancer biomarkers: the role of structured data reporting.

CONTEXT: The College of American Pathologists has been producing cancer protocols since 1986 to aid pathologists in the diagnosis and reporting of cancer cases. Many pathologists use the included cancer case summaries as templates for dictation/data entry into the final pathology report. These summaries are now available in a computer-readable format with structured data elements for interoperability, packaged as "electronic cancer checklists." Most major vendors of anatomic pathology reporting software support this model. OBJECTIVES: To outline the development and advantages of structured electronic cancer reporting using the electronic cancer checklist model, and to describe its extension to cancer biomarkers and other aspects of cancer reporting. DATA SOURCES: Peer-reviewed literature and internal records of the College of American Pathologists. CONCLUSIONS: Accurate and usable cancer biomarker data reporting will increasingly depend on initial capture of this information as structured data. This process will support the standardization of data elements and biomarker terminology, enabling the meaningful use of these datasets by pathologists, clinicians, tumor registries, and patients.

Prior high-risk human papillomavirus testing and Papanicolaou test results of 70 invasive cervical carcinomas diagnosed in 2012: results of a retrospective multicenter study.

CONTEXT: Persistent high-risk human papillomavirus (hrHPV) infection is essential for the development of cervical cancer and its precursor lesions. High-risk HPV testing has a higher sensitivity than cytology does for detecting cervical epithelial lesions. However, a large study from a single institution showed 31% of patients with invasive cervical cancer had negative baseline hrHPV testing within 5 years preceding the diagnosis. OBJECTIVE: To investigate the limitation of hrHPV testing in detecting invasive cervical cancer. DESIGN: Cases from 2012 with a histologic diagnosis of invasive cervical carcinoma were retrieved from multiple institutions. From those records, prior hrHPV testing and Papanicolaou test results in the 5 years before the cancer diagnosis were recorded. RESULTS: Seventy patients with cervical carcinoma were included in the study. Negative HPV test result rates were 9% (5 of 53), 23% (6 of 26), and 25% (2 of 8) during the periods of less than 1 year, 1 to 3 years, and 3 to 5 years before the histologic diagnoses, respectively. Negative Papanicolaou testing results in the same time intervals were 3.4% (2 of 59), 33% (10 of 30), and 40% (6 of 15). Although the HPV(-) rate seemed to be different among different HPV test methods, no statistical significance was detected because of small sample size. Negative hrHPV rates in patients with adenocarcinoma were similar to those in patients with squamous cell carcinoma. CONCLUSIONS: These data expose limitations for the potential use of primary HPV testing. In addition, current screening guidelines recommending cotesting at 5-year intervals should be evaluated further with additional historic data collection because there are women with negative results for both Papanicolaou tests and hrHPV testing within the period of 3 to 5 years before an invasive carcinoma diagnosis.

Changing the cytology laboratory information system to improve cytology performance.

A central tenet in the Patient Protection and Affordable Care Act is the increased use of information technology to improve patient care. However, areas for improvement in cytology are not well defined. Improvements in information technology could improve quality assessment in gynecologic cytology, but the cytology community must identify and ask for changes in information technology that can improve the care of patients.

Issues in reporting cytology: From headers and critical values to categorical data and natural language parsers.

The standards for reporting cytology, including critical values in cytology, are rapidly evolving. The issues and standards for the use of headers, reporting critical values, and the switch to categorical data elements are reviewed. The way in which cytology is reported is evolving, and the amount of information that is routinely generated from that report is increasing.

Prospective and retrospective review of gynecologic cytopathology: findings from the College of American Pathologists Gynecologic Cytopathology Quality Consensus Conference working group 2.

CONTEXT: Two quality metrics for gynecologic cytology are the subject of this review: "prospective rescreening" and "retrospective rescreening." OBJECTIVE: To offer consensus best practice approaches based on the College of American Pathologists' laboratory-based survey funded by the Centers for Disease Control and Prevention. DESIGN: The College of American Pathologists submitted a paper-based survey to 1245 laboratories. After review of initial results, follow-up Web-based survey results, and a literature review, consensus best practice statements were presented at a national consensus conference. These statements were discussed and voted upon by conference participants. Results.-A total of 541 laboratories responded to survey questions about prospective and retrospective rescreening. Most laboratories (>85%) prospectively rescreen more than 10% of Pap tests interpreted as negative for intraepithelial lesion or malignancy. Most (72%) report inclusion of less than 20% high-risk cases. Most laboratories use multiple measures to define "high risk." Most laboratories (96.2%) retrospectively rescreen Pap tests from the preceding 5 years only. In most laboratories (71.4%) only Pap test results with high-grade squamous intraepithelial lesion or worse prompt retrospective review. CONCLUSIONS: The number of Pap tests from high-risk patients should be maximized in prospective and retrospective rescreening. Unsatisfactory Pap tests should also be included. All readily identifiable high-risk human papillomavirus-positive cases with an interpretation of negative for intraepithelial lesion or malignancy should be prospectively rescreened. Cervical biopsy results with high-grade cervical intraepithelial neoplasia or worse (CIN 2+) should trigger retrospective rescreening. Regular feedback should be provided to cytotechnologists and cytopathologists. Upgraded diagnoses from negative for intraepithelial lesion or malignancy to atypical squamous cells, cannot exclude high-grade squamous intraepithelial lesion, should be monitored.

Immunohistochemical detection of estrogen receptor, progesterone receptor and human epidermal growth factor receptor 2 in formalin-fixed breast carcinoma cell block preparations: correlation of results to corresponding tissue block (needle core and excision) samples.

Evaluation of ER, PR and Her 2 are routinely performed on breast carcinomas. For accurate detection of these markers, compliance with the ASCO/CAP guidelines is recommended. Our previous study showed that alcohol fixation did not affect ER results when alcohol-fixed cell block (CB) sections were compared to formalin-fixed tissue sections, while PR and Her2 showed less concordance. The aim of this study was to evaluate and to compare ER, PR and Her2 IHC results on formalin-fixed CB sections to those observed on subsequent surgical (needle core or resection) specimens (SS). Fifty cases of formalin fixed CB samples obtained from primary (18%) and metastatic (82%) breast carcinomas were studied, all of which had subsequent SS available. ER, PR, and Her2 IHC studies were done on all samples and results were compared. ER results on formalin-fixed CB samples showed excellent correlation with SS (correlation coefficient cc = 0.82). While there was minimal improvement in PR results (cc = 0.433), Her2 detection did not improve by formalin fixation (cc = 0.439). Formalin fixation for CB preparations does not significantly improve the already good detection of ER positive breast tumors. The concordance rate in PR and IHC results between formalin-fixed CB and SS samples showed improvement as compared with the alcohol-fixed CB results. However, there was no improvement in detection of Her2 overexpression by using formalin fixation on cytology specimens.

Immunohistochemical detection of estrogen receptor, progesterone receptor, and human epidermal growth factor receptor 2 expression in breast carcinomas: comparison on cell block, needle-core, and tissue block preparations.

BACKGROUND: Fine-needle aspiration (FNA) is a rapid and accurate procedure for the detection of breast carcinomas. The evaluation of estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2) expression by immunohistochemistry (IHC) is performed routinely on formalin-fixed, paraffin-embedded needle-core (NC) or excision tissue block (TB) preparations, according to the American Society of Clinical Oncology/College of American Pathologist guidelines. In this retrospective study, the authors compared expression levels of ER, PR, and HER2 in ethanol-fixed BC FNA cell block (CB) samples with expression levels in formalin-fixed NC and TB samples. METHODS: Forty-one breast carcinoma CB samples with concurrent or subsequent NC and TB samples were identified. Patients who had received neoadjuvant or adjuvant chemotherapy were excluded. CB samples initially were fixed in 50% ethanol (4-12 hours), and this was followed by formalin fixation (minimum, 6 hours). NC samples were placed promptly in formalin for a minimum of 6 hours. Within 4 to 8 hours, TB samples were fixed in formalin for 6 to 48 hours. Fluorescence in situ hybridization (FISH) results were also compared. RESULTS: IHC for ER on alcohol-fixed CB samples had good correlation with NC and TB samples. PR results on TB samples had excellent agreement with NC samples. A higher discordance rate wais observed when PR results were compared between CB samples and NC samples. HER2 detection on ethanol-fixed CB samples resulted in a higher rate of positive and equivocal staining than NC or TB samples. HER2 IHC on TB samples demonstrated better correlation with FISH results than CB or NC samples. CONCLUSIONS: Alcohol fixation did not affect ER results in breast carcinoma, but it may alter tumor cell PR antigenicity. The authors concluded that CB samples could be used to triage patients for tamoxifen therapy, but they are not reliable for the assessment of HER2 status; therefore, CB results should be correlated with results from NC or TB samples.
