Abstract
Background Cervical cancer is common worldwide. Despite the existence of primary and secondary prevention strategies, the survival rate is decreasing in France due to an increasing proportion of advanced-stage cancer. Our objective was to determine the factors associated with a diagnosis of cervical cancer at advanced stages in an urban population in France. Methods A retrospective study was conducted on all consecutive records of patients diagnosed with cervical cancer between January 2006 and December 2018 in a single center in Paris. The data collected were demographic characteristics, medical and gynecological history, circumstances of diagnosis, diagnostic and therapeutic management. The patients were divided into two groups according to the FIGO 2018 stage at diagnosis: group A stages IA1 to IB2 and group B advanced stages IB3 to IVB. Results Among 96 patients who were diagnosed with cervical cancer, 25 (26%) were in group A and 71 (74%) in group B. Women in group B had less frequently received regular gynecological care than in group A (36% vs 84.2%, p < 0.001) and fewer had Pap test screening in the previous 3 years (30.4% vs 95.0%, p < 0.001). Parity greater than 3 was more frequent in group B (69.6% vs 42.9%, p = 0.031). The diagnosis was made during a routine examination or cervical smear in only 9.23% and 16.18% respectively in group B, versus 60% of cases in 45.82% of cases in group A (p < 0.001 and p = 0.003). Vaginal bleeding was observed in 85.29% in group B versus 36% in group A (p < 0.001). Histological type was squamous cell carcinoma 87.32% of group B and 56% of group A (p < 0.001). Conclusion Diagnosis of cervical cancers at advanced stages occurred mostly in women who did not benefit from the recommended screening. Universal access to screening is necessary for the prevention and early treatment of cervical cancer.

False-negative Papanicolaou tests in women with biopsy-proven invasive endocervical adenocarcinoma/adenocarcinoma in situ: a retrospective analysis with assessment of interobserver agreement. J Am Soc Cytopathol 2022; 11:3-12. [PMID: 34583894 DOI: 10.1016/j.jasc.2021.08.001] [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: 06/09/2021] [Revised: 07/23/2021] [Accepted: 08/03/2021] [Indexed: 06/13/2023]
Abstract
INTRODUCTION The objectives of our study were to identify factors contributing to false-negative Papanicolaou (Pap) tests in patients with endocervical adenocarcinoma (EA) or adenocarcinoma in situ (AIS), and to analyze the impact of educational instruction on interobserver agreement in these cases. MATERIALS AND METHODS False-negative Pap tests from patients with EA/AIS were reviewed by a consensus group and by 12 individual reviewers in 2 rounds, with an educational session on glandular neoplasia in Pap tests conducted between the 2 rounds. RESULTS Of 79 Pap tests from patients with EA/AIS, 57 (72.2%) were diagnosed as abnormal and 22 (27.8%) as negative. Of the 22 false-negative cases, 10 remained negative on consensus review, with false-negative diagnoses attributed to sampling variance. The other 12 cases were upgraded to epithelial abnormalities (including 8 to glandular lesions). The false-negative diagnoses were attributed to screening variance in 2 cases and interpretive variance in 10 cases. On individual review, abnormal cells were misinterpreted as reactive glandular cells or endometrial cells in 7 of 8 and 5 of 8 cases upgraded to glandular abnormalities, respectively. With education, the proportion of individual reviewers demonstrating at least moderate agreement with the consensus diagnosis (Cohen's kappa >0.4) increased from 33% (4 of 12) to 75% (9 of 12). CONCLUSIONS Sampling and interpretive variance each accounted for nearly one-half of the false-negative Pap tests, with underclassification as reactive glandular or endometrial cells the main source of the interpretive variances. Educational instruction significantly decreased the interpretive variance and interobserver variability in the diagnosis of glandular abnormalities.

Abstract
INTRODUCTION Recognition of adenocarcinoma in situ (AIS) in cervical cytology is challenging. MATERIALS AND METHODS We calculated the sensitivity and accuracy of Papanicolaou (Pap) tests obtained within 1 year of a histologic diagnosis of AIS from 2007 to 2016. We also correlated it with the coexistence of squamous lesions, calculated the interobserver agreement, and compared these measures with those of endocervical adenocarcinoma (ECCA). We correlated AIS detection with high-risk human papillomavirus (hrHPV) status. RESULTS Of 72 patients with histologic AIS and 48 patients with ECCA, 92% and 87.5%, respectively, had abnormal Pap test results. A glandular abnormality was detected in 44.4% of the AIS and 77.1% of the ECCA cases. Complete cytohistologic concordance was reached in 8.3% of AIS and 22.9% of ECCA cases. In addition, 27.8% of AIS and 6.3% of ECCA cases were diagnosed on Pap as a high-risk squamous abnormality. Concurrent squamous lesions were present in 79.2% of patients with AIS and 29.2% of patients with ECCA. The Paps from the AIS and ECCA cases were diagnosed as pure squamous abnormalities in 47.2% and 10.4% of cases, respectively. In the AIS cases, interobserver agreement was substantial for detection of any high-risk cytologic abnormality (kappa = 0.67) and fair for detection of any glandular abnormality (kappa = 0.34). Among the 26 patients with AIS tested for hrHPV, 92% had positive results and 8% had negative results. CONCLUSIONS The cytologic sensitivity for the detection of AIS remains low. It is directly related to the coexistence of squamous lesions. Cytology and hrHPV as stand-alone screening tests fail in the early detection of a small proportion of glandular lesions, although combined testing will improve their detection rates.

False-Negative Interpretation of Adenocarcinoma In Situ in the College of American Pathologists Gynecologic PAP Education Program. Arch Pathol Lab Med 2017; 141:666-670.

Abstract
CONTEXT - Adenocarcinoma in situ (AIS) is difficult to correctly interpret on Papanicolaou (Pap) cytology slides and false-negative interpretations of AIS can cause significant problems in daily practice. OBJECTIVE - To investigate the false-negative interpretation rate of AIS and the factors related to false-negative interpretation through responses in an educational environment. DESIGN - We retrospectively evaluated 11 337 responses in the PAP Education Program (PAP-Edu) from 173 AIS slides from 2011 to 2015. The false-negative interpretation rate, most common false-negative interpretations, and related other factors were evaluated. RESULTS - The overall false-negative rate was 6.9% (784 of 11 337). Respondents correctly interpreted AIS 50.0% (5667 of 11 337) of the time; high-grade intraepithelial lesion (HSIL) and malignancies (adenocarcinoma, squamous cell carcinoma, and other carcinomas) accounted for 42.7% (4842 of 11 337) and low-grade intraepithelial lesion accounted for 0.4% (44 of 11 337) of responses. Overall, 92.7% (10 509 of 11 337) of responses were HSIL and above. Among 784 false-negative responses, negative for intraepithelial lesion or malignancy was the most common (61.5% [482 of 784]), followed by reparative changes (24.1% [189 of 784]) and atrophic vaginitis (7.7% [60 of 784]). Overall, pathologists' responses showed a significantly higher false-negative rate than cytotechnologists' responses (8.3%, 403 of 4835 versus 5.7%, 275 of 4816; P < .001). The false-negative response rates were not statistically different among preparation types. CONCLUSIONS - The low correct interpretation rate and higher false-negative rate for AIS demonstrate the difficulty in interpreting AIS on Pap cytology, which may cause clinical consequences. The higher false-negative rate with pathologists than with cytotechnologists suggests cytotechnologists' higher screening sensitivity for AIS or cautious interpretation to avoid false-positive results by pathologists.

Cytojournal 2016; 13:28. [PMID: 28105064 PMCID: PMC5200999 DOI: 10.4103/1742-6413.196237] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2016] [Accepted: 06/18/2016] [Indexed: 11/25/2022] Open
Abstract
Background: The goal of this study was to calculate the sensitivity and false negative (FN) rate of ThinPrep Pap Test (TPPT) and carefully analyze missed cases for educational purposes. Materials and Methods: Patients with histologically proven adenocarcinoma in-situ (AIS) or invasive endocervical adenocarcinoma (EAC) over a 17-year-period (1998-2015) were identified. The TPPT immediately preceding the histological diagnosis of AIS/ECA was designated as index Pap (IP). Paps up to 122 months before histologic diagnosis of AIS/ECA were considered for this study. All available negative and unsatisfactory TPPT were re-reviewed. Results: There were 78 patients with histologically-proven AIS (56) or ECA (22) with 184 TPPTs, and 95 of these TPPTs were abnormal. Of the abnormal cases, 55.7% TPPTs were diagnosed as endocervical cell abnormality (atypical endocervical cells/AIS/ECA). Notably, 44.2% of abnormal TPPTs were diagnosed as squamous cell abnormality (atypical squamous cells of undetermined significance/low-grade squamous intraepithelial lesion/high grade squamous intraepithelial lesion). Including the diagnoses of squamous cell abnormality, the sensitivity of index TPPT for histologically-confirmed AIS/ECA was 88%. Eighty-eight of 184 TPPT, including 10 IP, were negative = 87, or unsatisfactory = 1. Forty-two of these slides were available for re-review. Upon review, 21 TPPT (50%) were confirmed negative and 21 TPPT (50%) were reclassified as abnormal = 20, or unsatisfactory = 1. Of the FN cases, the main difficulty in correct diagnosis was the presence of few diagnostic cell clusters which had less feathering, and consisted of smaller, rounder cells in small and tighter clusters, with nuclear overlap. In particular, nuclear overlap in three-dimensional groups precluded the accurate diagnosis. Rare FN cases showed squamous cell abnormality on re-review, and rare cases showed obscuring blood or inflammation. Conclusion: A significant proportion of AIS/EAC is discovered after Pap showing squamous cell abnormality. FN cases were most commonly related to nuclear overlap in tight three-dimensional clusters.

Prognosis of Cervical Cancer in the Era of Concurrent Chemoradiation from National Database in Korea: A Comparison between Squamous Cell Carcinoma and Adenocarcinoma. PLoS One 2015; 10:e0144887.

Abstract
In 1999, the National Cancer Institute issued a clinical advisory strongly touting the advantage of cisplatin-based chemoradiation (CCRT) for cervical cancer patients requiring radiation for their treatment. This study aimed to compare survival outcomes of cervical squamous cell carcinoma and adenocarcinoma before and after the advent of CCRT. Data were obtained from the Korea National Cancer Incidence Database for patients who were diagnosed with cervical cancers between 1993 and 2012. We compared survival according to histologic subtypes in cervical cancer patients diagnosed before (1993–1997), during (1998–2002), and after (2003–2012) the introduction of CCRT. A total of 80,766 patients were identified, including 64,531 (79.9%) women with squamous cell carcinomas and 7,265 (9.0%) with adenocarcinoma. With the introduction of CCRT, survival trends gradually increased in patients of both histologic subtypes with regional tumors. However, survival was significantly higher in squamous cell carcinoma than in adenocarcinoma patients regardless of treatment modalities (surgery alone, P < 0.001; surgery followed by CCRT, P < 0.001; or primary CCRT, P = 0.003). Multivariate analysis showed that adenocarcinoma was an independent negative prognostic factor for survival regardless of the time period (before CCRT, hazard ratio (HR) = 1.49; 95% confidence interval (CI), 1.37–1.62; after introduction of CCRT, HR = 1.40; 95% CI, 1.30–1.50). Although the survival of adenocarcinoma has improved after the introduction of CCRT, adenocarcinoma is still associated with worse overall survival compared to squamous cell carcinoma in the era of CCRT.

Cytological variations and typical diagnostic features of endocervical adenocarcinoma in situ: A retrospective study of 74 cases. Cytojournal 2015; 12:8.

Abstract
Background: The sensitivity of Papanicolaou smears for detecting endocervical adenocarcinoma in situ (AIS) is very low. A comprehensive cytological analysis of endocervical AIS is necessary to increase diagnostic accuracy. Methods: The subjects were 74 patients with pathologically-diagnosed AIS. A total of 140 Papanicolaou smears were reviewed to calculate the sensitivity of the Papanicolaou smears for detecting AIS and the incidence of sampling/screening/diagnostic errors. The cytological review was performed by 6 cytotechnologists, and the final cytological diagnosis was obtained at the consensus meeting. We classified the cases into three differentiation types; typical type (well-differentiated AIS), polymorphic type (poorly differentiated AIS), and mixed typical and polymorphic type. Three cytological subtypes (endocervical, endometrioid and intestinal subtypes) of AIS were also analyzed. Results: The sensitivity of the original Papanicolaou smears for the detection of AIS was 44.6%, while that for the detection of AIS and adenocarcinoma was 63.5%. The diagnostic accuracy of AIS increased to 78.5% in the final diagnosis. The common characteristic features were microbiopsies/hyperchromatic crowded groups (HCG) (82.0%) and mitotic figures (72.2%). The appearance of single cells (2.8%) was rare, and all the cervical cytology smears showed no evidence of necrotic tumor diathesis. The most common AIS was the typical type (41 cases, 67.2%) among all cytologically-diagnosed AIS or adenocarcinoma cases (61 cases). Although mixed typical and polymorphic AIS existed in 17 cases (27.9%), pure polymorphic AIS was very rare (3 cases, 4.9%). The endocervical subtype was the most predominant subtype (67.2%), followed by a few mixed subtypes. The important diagnostic keys for AIS cytology are as follows: (1) The appearance of microbiopsies/HCG (single-cell pattern is rare), (2) mitotic figures in the microbiopsies/HCG, (3) a lack of necrotic tumor diathesis in cases with polymorphic AIS, and (4) recognition of typical cytological subtypes. Conclusions: The relatively low diagnostic accuracy AIS was caused by the underestimation of microbiopsies/HCG and the overestimation of polymorphic components. The typical cytological features of AIS are the presence of microbiopsies/HCG with mitotic figures in the absence of necrotic tumor diathesis in specimens containing endocervical samples. The recognition of infrequent AIS subtypes (endometrioid and intestinal subtypes) is also important.

Abstract
Stratified mucin-producing intraepithelial lesion (SMILE) of the cervix is a human papilloma virus (HPV) associated high grade intraepithelial columnar cell neoplasm that is thought to arise from the reserve cells of the transformation zone. It is composed of immature stratified cells that display intracytoplasmic mucin and is commonly associated with high grade squamous intraepithelial lesion (HSIL), adenocarcinoma in situ (AIS), and invasive carcinoma. Here, we describe the cytologic features of SMILE and discuss its pitfalls in cervical cytology. A 51-year-old woman was diagnosed with SMILE on a cervical biopsy. Histologically, the dysplastic epithelium showed enlarged nuclei with increased nuclear density and presence of mucin-producing columnar cells throughout its thickness. The slides from the last two Pap tests (ThinPrep) performed on the patient were reviewed and compared with the histology. Cytologically, groups of atypical endocervical glandular cells were seen on both Pap tests. These groups showed mild nuclear crowding, slightly enlarged nuclei, nuclear hyperchromasia, and indistinct nucleoli. The borders of these cell groups were relatively smooth. Original cytologic diagnosis was atypical squamous cells of undetermined significance (ASC-US) in both instances. HPV (Hybrid Capture 2) testing was positive on both occasions. Similar to the histology, cytologic features of SMILE are subtle. The features are not typical for AIS or for HSIL and could easily be misinterpreted as reactive. This report emphasizes that careful review of crowded groups of glandular cells in HPV positive women is absolutely critical. Based on our knowledge, this is the first description of the cytologic features of these lesions.

Abstract
OBJECTIVE Our study aims to describe changes in carcinoma in situ (CIS) and invasive cervical carcinoma (ICC) in Korean women diagnosed between 1993 and 2009. METHODS All cases of CIS and invasive cervical carcinoma diagnosed from 1993 to 2009 in the Korean National Cancer Incidence database were analyzed. Age-standardized rates (ASRs) and annual percent changes (APCs) in incidence rates were compared according to age and histological type. Additionally, we used Korea National Health and Nutrition Examination Survey (KNHANES) to know the association between screening rate for cervical cancer and incidence rate of cervical cancer. RESULTS Between 1993 and 2009, 72,240 cases of ICC were reported in Korea. Total incidence rate of ICC was 14.7 per 100,000 females. ASRs of ICC declined 3.8% per year, from 19.3 per 100,000 in 1993 to 10.5 per 100,000 in 2009. Although the overall incidence rate of adenocarcinoma remained stable, invasive squamous cell carcinoma showed a decreasing trend (APC -4.2%). For women aged 60-79 years, ASRs for squamous cell carcinoma increased from 1993 to 2001, and decreased from 2001 to 2009 (APC: -4.6%). Total 62,300 cases of CIS were diagnosed from 1993 to 2009. Total incidence rate of CIS was 12.2 per 100,000 females. ASRs of CIS increased 5.7% per year, from 7.5 per 100,000 in 1993 to 19.0 per 100,000 in 2009. Adenocarcinoma in situ increased 13.2% per year. There was a strong positive correlation between screening rate for cervical cancer and incidence rate for CIS (p-value = 0.03) whereas screening rate showed a strong negative correlation with incidence rate for squamous ICC (p-value = 0.04). CONCLUSIONS The increasing trend in CIS, coupled with a decreasing trend in ICC, suggests the important role of cervix cancer screening. The incidence of adenocarcinoma showed a plateau, but the incidence of adenocarcinoma in situ showed an increasing trend.

Abstract
OBJECTIVE The purpose of the study was to perform a national review of negative, low-grade and inadequate smears reported during the latest screening period before cervical cancer diagnosis in 2006, after the first 3 years of the screening programme. METHODS Among 162 new cervical cancer cases there were 47 (29%) without previous cytology, 47 (29%) with one high-grade smear prior to diagnosis and 68 (42.0%) with at least one previous negative, low-grade, atypical or inadequate smear 1-40 months before diagnosis. Of the latter 68 cases, 37 patients with 59 smears (together with 118 control slides) were included in the review as 31 had smears reported at laboratories no longer operating. Findings were related to the last cytology report before diagnosis as well as to histological type and stage of the cancer. RESULTS In our study group, 19 (51%) of 37 patients had squamous cell carcinoma, 15 (41%) adenocarcinoma and 3 (8%) adenosquamous carcinoma, compared with 121 (75%), 26 (16%), 12 (7%), respectively, and 3 (2%) other types, for all carcinomas. Twenty-one of 37 women also had high-grade cytology prior to diagnosis of cancer. Women with previous cytology (with or without recent high-grade smears) were more likely to have stage I cancers than those without cytology (P < 0.0001). The expert group upgraded 17/33 smears in the patients with squamous carcinomas, which was more than in those with adeno- and adenosquamous carcinomas (5/24, P < 0.05). CONCLUSION As expected, a higher proportion of smears preceding adenocarcinomas were true negative. Under-diagnosed smears were not related to cancer stage or last cytology report before diagnosis.

Abstract
CONTEXT Liquid-based preparations (LBPs) and human papillomavirus testing have led to changes in cervical cytology practices. The College of American Pathologists attempts to track practice patterns using a supplemental questionnaire, which allows laboratories to report diagnostic practices. OBJECTIVE To analyze the 2006 reporting practices and to compare the results with the 2003 survey data. DESIGN Questionnaire was mailed to 1621 laboratories. Participants included laboratories enrolled in the 2006 College of American Pathologists Gynecologic Proficiency Testing Program or the educational Interlaboratory Comparison Program in Gynecologic Cytology. RESULTS Of the 679 responding laboratories (response rate, 42%), most (97.8%; n = 664) had implemented the Bethesda 2001 terminology. The median rate for all preparations with low-grade squamous intraepithelial lesions was 2.5% (2.9% for LBPs) compared with a 2003 median rate of 2.1%; the increase was confined to LBPs. Rates for high-grade squamous intraepithelial lesions (median, 0.5%) and atypical squamous cells have changed little. High-grade squamous intraepithelial lesions and unsatisfactory rates varied at statistically significant levels between types of LBPs. Most atypical squamous cell cases were subclassified as undetermined significance (median, 4.3%). The median ratio of atypical squamous cells to squamous intraepithelial lesions and carcinomas for all specimen types combined was 1.5, similar to the 2003 median ratio of 1.4. The median rates for findings of squamous cell abnormalities for 2006 were significantly higher for LBPs than for conventional smears. CONCLUSIONS Most responding laboratories have implemented the Bethesda 2001 terminology. There is an increase in LBP low-grade squamous intraepithelial lesion rates when compared with 2003 data. Liquid-based preparations have higher median squamous intraepithelial lesion and atypical squamous cell rates.

Abstract
BACKGROUND Although cervical cancer incidence has declined in the past decade, considerable racial and ethnic differences remain. The objective of this study was to examine differences in incidence by histology and cancer stage in Florida stratified further by race, ethnicity, and 5-year time intervals. METHODS Women who were diagnosed with invasive cervical cancer in Florida between January 1985 and December 2004 were included in the analysis. Age-adjusted incidence rates by race and ethnicity were estimated for different histologic types and stages of cancer. The annual percentage of change in incidence also was calculated for each histologic type. Rate ratios were estimated by race and ethnicity using whites and non-Hispanics as the reference group. RESULTS Overall, the incidence in Florida of cervical squamous cell carcinoma and transitional cell carcinoma declined significantly from 9.1 per 100,000 women in 1985 to 5.6 per 100,000 women in 2004 (P < .05), whereas the incidence of cervical adenocarcinoma remained stable (P > .05). The incidence of invasive cervical cancer was 9.6 per 100,000 women among whites and 13.13 per 100,000 women among African Americans from 2000 to 2004. African-American women were nearly 2 times more likely to be diagnosed at regional and distant cancer stages than white women for all periods examined. Furthermore, among African-American women aged >40 years, the age-specific incidence of invasive cervical cancer increased considerably, whereas the rates among other racial groups decreased. CONCLUSIONS The increasing rate of invasive cervical cancer among African-American women aged >40 years in Florida, coupled with their diagnosis at a later stage of cancer, is of great concern. Most screening organizations recommend stopping screening at age 65 years. The observations from these analyses highlighted the need to focus prevention and screening efforts on African-American women living in Florida, and particularly on women of postreproductive age.

Abstract
OBJECTIVE To better understand national patterns of invasive cervical cancer (ICC) incidence by race and ethnicity in order to develop appropriate ICC prevention policies. METHODS Age-adjusted and age-specific ICC incidence rates were calculated by combined race/ethnicity, making distinct the Hispanic/all races category from three other Non-Hispanic (White, Black and other) racial categories. RESULTS There was a significant downward trend in ICC incidence during both time periods for every combination of race/ethnicity (p-value <0.05) except Hispanic/all races during 1995-1999. Non-Hispanic/Black and Hispanic/all races women had significantly higher incidence rates of ICC compared to Non-Hispanic/White women. ICC incidence peaked much earlier for Non-Hispanic/White women (35-44 years of age) compared to any other racial/ethnic group. Non-Hispanic (White, Black and other) women had lower rates of adenocarcinoma and squamous cell carcinoma compared to Hispanic/all races women. Non-Hispanic/Black and Hispanic/all races women were more likely to be diagnosed at late stage or unstaged at diagnosis than Non-Hispanic/White women. CONCLUSION Although ICC incidence decreased significantly over the last 10 years, Black or Hispanic US populations continue to have the highest ICC incidence compared to Non-Hispanic/Whites, highlighting the need for improved health literacy and social support to ensure their equal access to ICC screening and HPV prevention including HPV vaccination.

Abstract
Objectives:To determine predictors of cervical cancer survival by socioeconomic status (SES), urbanization, race/ethnicity, comorbid conditions, and treatment among elderly Medicare-eligible women whose conditions were diagnosed with cervical cancer in a multiethnic population.Methods:A total of 538 women with cervical cancer aged 65 years or older were identified from 1999 to 2001 from the Texas Cancer Registry and were linked with the state Medicare data and Texas Vital Records to determine survival times. All women had similar access to care through Medicare fee-for-services insurance. A composite measure of SES was created using census tract-level data as was urbanization. Treatment and comorbid conditions were available from the Medicare data. Cox proportional hazards modeling was used for all-cause and cervical cancer-specific survival analysis.Results:Increased age (P < 0.0001) and advanced tumor stage (P < 0.0001) were associated with poorer all-cause and cervical cancer-specific survival. Having a comorbid condition was associated with all-cause survival (P < 0.01) but not cervical cancer-specific mortality. After adjusting for confounders, women receiving some form of treatment were almost half as likely to die with cervical cancer (adjusted hazard ratio = 0.68; 95% confidence interval, 0.52-0.89). After adjustment for all confounders, Hispanic women consistently had lower all-cause and cervical cancer-specific mortality rates relative to non-Hispanic white and non-Hispanic black women.Conclusions:Among women with similar health care coverage, Hispanic women had consistently lower all-cause and cervical cancer-specific mortality rates than other older women whose conditions were diagnosed with this disease in Texas. The presence of comorbid conditions and treatment were important predictors of survival, yet these factors do not explain the survival advantage for Hispanic women.

Abstract
BACKGROUND Rapid rescreening (RR) of negative Papanicolaou smears (PS) is used in many countries as a quality-assurance measure. Seeding of abnormal slides has been suggested as a way to increase the sensitivity of this procedure. Since 2004, the authors have carried out RR with seeding before issuing reports. In this article, they describe their experience. METHODS Abnormal seeds were sourced from the previous day's high-grade cases, both squamous and glandular. Slides were evaluated for the 'degree of difficulty' (which was defined as the number of fields required to find (fields-to-find [FTF]) the abnormality), relabeled, and redotted to make them indistinguishable from the routine RR work. The number of seeds found/missed, the identity of the screener, the type of seeded abnormality, the degree of difficulty of the seed, and the mapping technique used all were recorded. The cytologists also were surveyed about their views on seeding. RESULTS Overall, 14.8% of 3082 high-grade seeds were missed during RR. There was no relation between seeds missed and the mapping technique used. However, the difficulty of the seed was relevant to the number missed and ranged from 8.3% when the FTF was <5 to 36% when the FTF was >10 (P = .000). The difference between intraepithelial seeds and invasive seeds was significant for squamous seeds (P = .031) but not for glandular seeds. Glandular seeds also were more likely to be missed than squamous seeds (23.1% vs 14.3%; P = .002). Most cytologists believed that seeding was a good idea and that seeds increased their level of vigilance. CONCLUSIONS The authors' experience demonstrated that routine seeding is practicable for both conventional and liquid-based slides. With the advent of the human papillomavirus vaccine, abnormalities will become rarer, and seeding will be necessary to maintain the alertness of cytologists.

Abstract
OBJECTIVE To provide updated management guidelines according to cervical cytology specimen adequacy and techniques to optimize adequacy based on literature review and expert opinion. MATERIALS AND METHODS Selected members of the American Society for Colposcopy and Cervical Pathology committee and invited experts conducted a literature review and discussed appropriate management and areas for future research emphasis. RESULTS The guidelines recommend a repeat Pap test in a short interval of 2 to 4 months for most women when the cytology result is unsatisfactory. The preferred follow-up for women with a negative cytology result lacking an endocervical/transformation zone component or showing other quality indicators is a repeat Pap test in 12 months. Indications for an early repeat Pap test in 6 months are provided, and the influence of human papillomavirus testing results on management is discussed. Techniques for optimizing specimen adequacy are provided in detail. CONCLUSION The specimen adequacy management guidelines will help promote uniform and optimal follow-up of patients receiving cervical cytology screening. The topics for future research emphasis will be helpful in promoting studies in needed areas.

Abstract
BACKGROUND Since the introduction of the Pap smear screening, the incidence of squamous cell carcinoma (SCC) has decreased significantly, but the incidence of adenocarcinoma (AC) relative to SCC has increased. AIM To compare the Pap smear history of patients with AC and SCC of the cervix. METHODS Patients for the study were identified from the database of Queensland Centre for Gynaecological Cancer. Patients with AC and SCC were matched for age at diagnosis and International Federation of Gynecology and Obstetrics stage. The final population included 188 matched pairs, being 376 patients in total. Data were collected upon the histological type of cancer, result of the most recent Pap smear, date and result of the Pap smear prior to the most recent Pap smear and symptoms. Chi-squared tests and Fisher's exact test were used to compare the two patient groups for several variables. RESULTS Patients with AC had significantly more false-negative results on their most recent Pap smear (P<0.0001) than patients with SCC. The incidence of symptoms such as bleeding and/or vaginal discharge was comparable in patients with AC and SCC. The time between the most recent Pap smear and the diagnosis of cervical cancer was significantly shorter for patients with AC (P=0.01). CONCLUSIONS Patients with AC had Pap smears more regularly than those with SCC, and their most recent Pap smear was significantly more likely to be normal. Thus, Pap smear prior to a diagnosis of AC is more likely than SCC false-negative and therefore not indicative of cervical cancer.

Abstract
Cervical cancer is not only the most frequently reported cancer among women, but also the most common female genital tract neoplasm in Taiwan. Early detection is effective, because the development, maintenance and progression of precursor lesions (cervical intraepithelial neoplasia [CIN]) evolve slowly into invasive cancer, typically over a period of more than 10 years. It is now recognized that human papillomavirus (HPV) infection is a necessary cause for over 99% of cervical cancer cases. Advances in the understanding of the causative role of HPV in the etiology of high-grade cervical lesions (CIN 2/3) and cervical cancer have led to the development, evaluation and recommendation of HPV-based technologies for cervical cancer prevention and control. The prevention of HPV infection before the onset of CIN is now possible with recently available prophylactic HPV vaccines, e.g. the quadrivalent Gardasil (Merck & Co., NJ, USA) and bivalent Cervarix (GlaxoSmithKline, London, UK). This review article provides an up-to-date summary of recent studies and available information concerning HPV and vaccination in cervical cancer.

Abstract
BACKGROUND The purpose of the current study was to examine the screening histories of women diagnosed with invasive cervical cancer (ICC) in 2000 who had previous Papanicolaou (Pap) smears deemed to be unsatisfactory or with low-grade findings that did not lead to biopsy. METHODS A total of 252 Pap smears from 47 women taken between 1992 and 2000 were included in the study; 247 smears were reexamined at the laboratory of origin before the study and all 252 were then reexamined independently by 2 experienced cytotechnicians and 2 cytopathologists. RESULTS Of the 47 cases of ICC, 35 were squamous cell carcinoma, 10 were adenocarcinoma, and 2 were other types. On reexamination at the laboratory of origin, 24 cases were upgraded and in the study group 27 cases were upgraded to diagnoses requiring biopsy. On reexamination at the laboratory of origin, it was found that the first high-grade squamous intraepithelial lesion (HSIL) could have been diagnosed on average 4.2 years earlier than it was originally (95% confidence interval [95% CI], 3.3-5.1 years). On reexamination by the study group the first diagnosis of HSIL was made in smears dating from 5.4 years before the diagnosis of ICC (95% CI, 4.5-6.2 years). CONCLUSIONS The study confirms that unsatisfactory and low-grade Pap smears imply a risk of developing high-grade lesions at a later date and shows that in a screening program a subgroup of smears may be diagnosed as unsatisfactory or low grade despite the presence of high-grade findings that are detectable on reexamination.

Abstract
CONTEXT Both gynecologic cytology and surgical pathology use similar methods to measure diagnostic error, but differences exist between how these methods have been applied in the 2 fields. OBJECTIVE To compare the application of methods of error detection in gynecologic cytology and surgical pathology. DATA SOURCES Review of the literature. CONCLUSIONS There are several different approaches to measuring error, all of which have limitations. Measuring error using reproducibility as the gold standard is a common method to determine error. While error rates in gynecologic cytology are well characterized and methods for objectively assessing error in the legal setting have been developed, meaningful methods to measure error rates in clinical practice are not commonly used and little is known about the error rates in this setting. In contrast, in surgical pathology the error rates are not as well characterized and methods for assessing error in the legal setting are not as well defined, but methods to measure error in actual clinical practice have been characterized and preliminary data from these methods are now available concerning the error rates in this setting.

Abstract
Hybrid capture is an easy and highly sensitive technique for screening population due to its capacity to detect malignant and premalignant lesions of the cervix. To evaluate its sensitivity, we investigated the frequency of high-risk human papillomavirus (HPV) infection and its correlation with glandular malignant lesions, analyzing a total of 113 cases of adenocarcinomas and related lesions. High-risk HPV was investigated using a hybrid capture II (HC2) assay. Samples were collected in two different ways: either brushed directly from surgical specimens before fixation or collected from the patients. We also investigated the frequency of HPV in squamous malignant lesions, 65 squamous cell carcinomas (SCC) and 66 in situ squamous cell carcinomas (ISSCC), to compare the occurrence of HPV for these lesions. The 113 glandular lesions comprised 62 invasive adenocarcinomas (IAC), 8 in situ adenocarcinomas (ISAC), 26 IAC plus SCC, and 17 adenosquamous cells carcinomas (ASCC). The HPV-positive reactions were as follows: 51 (82.2%) in IAC, 8 (100%) in ISAC, 25 (96.1%) in IAC plus SCC, and 14 (82.3%) in ASCC. HC2-positive results in the squamous malignant lesions were as follows: 58 of 63 (89.0%) for SCC and 94 of 103 (91.2%) for ISSCC. High-risk HPV infection was quite similar for glandular and pure squamous invasive malignant lesions, 82.2% and 89.0%, respectively, indicating that high-risk HPV is also highly prevalent in glandular lesions. Although hybrid capture proved to be an excellent adjunctive technique, we do not believe its results merit replacing the Pap smear as a screening tool.

Abstract
OBJECTIVES Tumor stage, age, and cell type are well-characterized predictors for cervical cancer survival; socioeconomic factors may also play an important role. The purpose of this study is to estimate cervical cancer survival by socioeconomic indicators and race/ethnicity among elderly women diagnosed with cervical cancer. METHODS We studied 1251 women with cervical cancer aged 65 or older, identified between 1992 and 1999 from the Surveillance, Epidemiology, and End Results [SEER]-Medicare linked data. All women had similar access to care through Medicare fee-for-services insurance. A composite measure of socioeconomic status was created using census tract level data for poverty, education, and income. Cox proportional hazard modeling was used for all-cause and cervical cancer-specific survival analysis. RESULTS Increased age (P < 0.0001) and advanced tumor stage (<0.0001) were associated with poorer all-cause and cervical cancer-specific survival. After adjustment for age, stage, and treatment, increased co-morbidity scores and having non-squamous cervical cancer were associated with poorer all-cause survival (P < 0.001). After adjusting for confounders, women receiving hysterectomy vs. no surgery or any treatment had significantly better all-cause and cervical cancer-specific survival. Socioeconomic factors were not associated with either all-cause (P for trend = 0.79) or cervical cancer-specific (P for trend = 0.81) survival. No racial/ethnic differences in all-cause or cervical cancer-specific survival were observed after adjusting for socioeconomic factors. CONCLUSION Among women with similar access to care, neither minority race/ethnicity nor poorer socioeconomic status were associated with poorer survival in this large sample of older women diagnosed with invasive cervical cancer. Presence of co-morbid conditions and treatment were important predictors of cervical cancer survival.

Abstract
BACKGROUND Multiple-slide, blinded review has been endorsed by several cytology and pathology organizations as the most appropriate method for the review of cervicovaginal specimens in the context of litigation. This process involves review of litigation slides in a blinded manner by multiple independent cytotechnologists and the comparison of those results with those of validation cases that are comprised of known abnormalities with biopsy follow-up. To the authors' knowledge, the results of this method have not been previously published. METHODS The results of the blinded review program at the Center for Cytopathology and Molecular Research at the Medical University of South Carolina for the years 1998-2004 were reviewed. RESULTS A total of 135 litigation slides and 122 validation slides were reviewed. The interpretations of these cases were found to be significantly different (P < 0.001). Litigation cases were significantly more likely to be interpreted as either negative for intraepithelial lesion (NIL) or atypical squamous cells/atypical glandular cells (ASC/AGC) (P < 0.001). The results appeared to be independent of the individual cytotechnologists involved. Approximately 10% of litigation cases were called at least ASC/AGC by all observers and 4% were interpreted as NIL by all observers. For litigation cases, ASC/AGC was found to be just as reproducible as high-grade squamous intraepithelial lesion. The results demonstrated that only 10% of litigation cases are regularly and reliably identified as abnormal, whereas a single review as performed by an expert cytologist can be expected to classify 56% of cases as abnormal. CONCLUSIONS This program suggests that a majority of litigation cases are not regularly and reliably identified as abnormal, and a single review will routinely overestimate the percentage of cases that are identified regularly and reliably.

Abstract
CONTEXT Characteristic cytologic features have been identified that distinguish cases that are consistently identified from those that are sometimes missed in the College of American Pathologists Gynecologic Cytology Program for a variety of different lesions and preparations. OBJECTIVES To compare the cytologic features of cases of adenocarcinoma, not otherwise specified (NOS), in conventional smears that perform poorly and well. DESIGN The cytologic features of 21 conventional smear cases of adenocarcinoma, NOS, that performed poorly in the College of American Pathologists Interlaboratory Comparison Program were compared with 17 cases that performed extremely well. RESULTS Cases that performed well were significantly more likely to have greater than 1000 abnormal cells (P = .006), greater than 100 large abnormal cells (P = .006), large nuclei (P < .001), marked nuclear atypia (P = .02), and hyperchromasia (P = .02). Repair-like features were rare in both groups and were not significant (P = .71). CONCLUSION Conventional smears with a diagnosis of adenocarcinoma that were consistently identified were significantly more likely to have more abnormal cells, larger abnormal cells, larger nuclei, marked atypia, and hyperchromasia than cases that performed poorly.

Abstract
The purpose of this review is to identify features that separate atypical glandular cells (AGC) associated with glandular neoplasia from its mimickers, both benign and neoplastic. We reviewed cases of AGC diagnosed on liquid-based Pap tests (LBP) for which corresponding histological follow-up was available. A review of the literature for similar studies in LBP tests was also conducted. We find that certain benign mimics can be reliably separated from AGC, but recommend caution in attempting to increase specificity at the risk of losing sensitivity. Although accounting for only a small percentage of diagnoses AGC require a thorough clinical evaluation, including colposcopy. Most cases are ultimately found to be benign. When evaluating smears suspicious for AGC, it is important to examine the subtle features which make truly atypical cells discernible from their numerous benign mimickers.

Abstract
In many developed countries, the incidence of cervical cancer has decreased. These reductions have been specific to squamous cell carcinoma (SCC) and have not included adenocarcinoma (AC). Incidence of AC has increased steadily over the last 20 years. The intent of this article is to examine trends in cervical adenocarcinoma incidence in Ontario over a 20-year period in relation to screening practices. All cases of cervical cancer between 1981 and 2002 were extracted from the Ontario Cancer Registry (a population-based, provincial-wide database). Age-standardized incidence rates were calculated overall, by broad age groups and by morphological type (SCC and AC). Time trends were assessed using JoinPoint methodology. In Ontario, opportunistic cervical cancer screening has been accompanied by significantly decreased rates of SCC since at least 1981. Conversely, the incidence of AC rose by 3.1% per year (95% CI: 1.6%, 4.6%) between 1981 and 1995, and subsequently declined by 4.0% per year (95% CI: -7.4%, -0.5%). From the mid- to late-1990s, instructions were distributed to clinicians, reinforcing the importance of dual specimen collection (i.e., using both spatula and endocervical brush). At the same time, laboratories routinely provided physicians with kits that included both spatula and brush. The subsequent decline in AC incidence may be due, in part, to improved specimen collection. As well, the decline may be partly due to increased awareness of AC precursors among cytopathologists and clinicians, and/or improvements in laboratory training and quality assurance.

Abstract
CONTEXT The 2001 Bethesda System for the reporting of cervical cytology specimens and the use of new liquid-based and human papillomavirus testing technologies have led to changes in cervical cytology reporting practices. OBJECTIVES To analyze current laboratory reporting practices using Bethesda 2001 terminology and to compare results with previous survey data from 1996. DESIGN Questionnaire survey mailed to 1751 laboratories in mid-2003. PARTICIPANTS Laboratories enrolled in the College of American Pathologists Interlaboratory Comparison Program in Cervicovaginal Cytology. RESULTS Of the 759 responding laboratories, most (85.5%) had implemented Bethesda 2001 terminology, and the majority had adopted major changes, such as elimination of the benign cellular changes category and the satisfactory but limited category. The median reporting rate for low-grade squamous intraepithelial lesion was 2.1%, compared to a 1996 median rate of 1.6%, but the increase was confined to liquid-based preparations. Reporting rates for high-grade squamous intraepithelial lesion (median, 0.5%) and atypical squamous cells (ASC) had changed little. Most ASC cases were subclassified as "undetermined significance" (median, 3.9%) with ASC, cannot exclude high-grade SIL accounting for a minority (median, 0.2%). The median ratio of ASC to squamous intraepithelial lesions and carcinomas (SIL+) was 1.4 and was lower than the 1996 median ratio of 2.0. Median reporting rates for squamous abnormalities for 2002 were noted to be significantly higher for liquid-based preparations than for conventional smears, while median ASC/SIL+ ratios were lower. Most laboratories offer human papillomavirus testing, but almost half (47%) of laboratories do not know the percentage of positive testing results in patients with ASC. CONCLUSIONS Most laboratories have implemented Bethesda 2001 terminology. New criteria and liquid-based methods have led to an increase in low-grade squamous intraepithelial lesion reporting rates and a decrease in ASC/ SIL+ ratios when compared with 1996 data. Liquid-based preparations have higher median squamous intraepithelial lesion rates and lower ASC/SIL+ ratios than conventional smears.

Abstract
OBJECTIVE To study P-cadherin aberrant expression as a possible marker for cervical adenocarcinomas in cytological samples. METHODS We studied P-cadherin immunoexpression in liquid-based cervical cytology samples of biopsy-proven cervical lesions. RESULTS We found a statistically significant correlation between P-cadherin expression and a cytological diagnosis of malignancy, either glandular or squamous (P < 0.0001). Twenty-two of 33 malignant cases showed P-cadherin membrane staining. None of the 30 benign cases tested showed membrane staining, but three of them displayed an aberrant nuclear P-cadherin expression. CONCLUSIONS We concluded that P-cadherin can be used to discriminate between malignant and benign cervical cytological specimens, but not to discriminate glandular from squamous lesions.

Abstract
OBJECTIVES To determine histologic positive predictive values (PPVs) for three categories of cytologic reports of endocervical glandular abnormalities. MATERIALS AND METHODS We obtained histologic follow-up for 100% of 67 cytologic predictions of adenocarcinoma in situ (AIS) and 82% of 39 predictions of possible AIS (?AIS) made over a 4-year period (1999-2002) and for 25% of 105 atypical endocervical cells (AEC) predictions over a 12-month period (2000). For each category of cytologic report, we determined the histologic yields of high-grade lesions overall and of high-grade glandular lesions. RESULTS PPVs for predictions of AIS and ?AIS for high-grade lesions overall were 91% and 75% (p = .032), respectively, and those for high-grade glandular lesions were 88% and 72% (p = .046), respectively. For a cytologic report of AEC, of those with histologic follow-up, 9% had a high-grade lesion and 7% had a high-grade glandular lesion. CONCLUSION Cytology can accurately predict AIS.

Abstract
OBJECTIVE In Slovenia the opportunistic cervical cancer (CC) screening programme has been performed within the regular gynaecological practice since 1960. The incidence rate 28.8/10(5) decreased to 16.1/10(5) in 1982, and increased to 23/10(5) in 1996. To explain the increased CC incidence the patients' screening histories, occurrence of symptoms, and details of preventive measures were studied on the basis of medical records and questionnaire. Errors of cytological screening were analysed by reviewing previous smears. MATERIAL The answers obtained from 324 women, treated for CC in the period 1995-2000, were analysed in relation to age, stage and histology. The mean women's age was 46.76 +/- 13.07 (S.D.) years (range 23-85 years). After therapy, 271 patients were followed-up by the end of January 2004, (mean follow-up time 80.3 +/- 20 S.D. months, range 29.7-110.3 months). Statistical analysis was performed using Chi-square test. RESULTS In 208 (80%) cases, CC was detected in stage 1, in 43 (17%) in stages 2A to 3B. Squamous-cell carcinoma (192, 74.1%) was followed by adenocarcinoma (61, 23.5%) and (5, 1.9%) other malignancies. The screening interval ranged from 6 months to 4 years. Statistically significant differences existed between clinical and screening variables. CC was diagnosed in higher stages in women who were ignorant of the Pap test. Re-screened smears (n = 126) showed 27.8% of false negative results. CONCLUSIONS The reasons for high incidence of CC are poor performance of cytological screening, failures in gynecological examinations and diagnostic procedures, and the patients' negligence of attending regular screening.
