Abstract
Aims To differentiate between two types of atypical squamous cells of undetermined significance (ASCUS): probably neoplastic (PN) or probably reactive (PR), and, in accordance with the recommendations on screening protocols of the Emilia-Romagna Region (PSRER), Italy, to define the best management to follow and the prognosis. Furthermore, the associations between ASCUS and infectious agents and human papillomavirus (HPV) were evaluated. Methods Fifty-eight ASCUS smears were reviewed and sorted; if a diagnosis of ASCUS was confirmed, the smear was classified as PR or PN, and the PSRER group was identified. Then, colposcopy was performed with checks for infectious agents (culture evaluation with cytological or clinical criteria) and HPV (hybrid capture). Results The ASCUS frequency was 3.96%. Of the 58 cases, 33 (56.9%) were diagnosed as ASCUS on review, of which 15 cases were PN and 18 were PR, while 23 (39.7%) smears were normal and 2 (3.4%) showed cervical intraepithelial neoplasia (CIN). There was a higher frequency of bacterial vaginosis (BV) and HPV in ASCUS PR patients compared with normal cytology, and a higher frequency of CIN in ASCUS PN patients compared with normal controls (P <0.05). By grouping ASCUS 1 and 3, we observed a higher frequency of CIN and of high-grade colposcopy findings compared with ASCUS 2 and 4 (P <0.05). From the 23 cases not found to be ASCUS, 18 (87.5%) had normal cytology and colposcopy results on the first follow-up. Conclusions Classification of ASCUS as either PN or PR helps in clinical conduct and prognosis, because a higher frequency of CIN is found in ASCUS PN. ASCUS subdivisions, based on PSRER and colposcopy, may facilitate the clinical conduct because ASCUS 1 and 3 with high-grade colposcopic findings proved to be related to the presence of CIN. We propose that initial ASCUS cytology be reviewed, and if it is confirmed, colposcopy should be performed. For those cases found to be normal on review of the cytology results, it is suggested that a cytological check-up be carried out every 6 months.

Abstract
BACKGROUND Atypical squamous cells of undetermined significance (ASCUS) is a term that refers to inflammatory, reactive and reparative processes which are atypical and of higher level and insufficient to be classified as cervical intraepithelial lesions (CIN). AIMS Examine of frequency of HPV infection in ASCUS lesions and regression, stagnation and progression during six-month period. SUBJECTS AND METHODS Prospective study was conducted over a period of 3 years. In private gynecological ambulance "Dr Mahira Jahic". Analysis of PAP smears and HPV typization have been done in 50 patients and PAP test has been repeated after six months. X² test was used for statistical analysis. RESULTS Analysis of 1784 PAP smears showed normal results in 86,6% (N-1530), and abnormal in 13% (N-254). ASCUS in 7,4% (N-133) and ASC-H in 0,5% (N-9), LSIL in 4,4% (N-80), HSIL in 1,3% (N-24), CIN II in 1,2% (N-20), CIN III in 0,2% (N-4). Progression occurred in 18% (9), persistence in 74% (37) and regression in 8%. Patients with ASC-H lesion 0,5% (N-9), PH results showed 22% (N-2) Carcinoma in situ, 33% (N-3) CIN II, 22% (N-2) CIN I and 22% (N-2) chronic cervicitis. Patients with CIN I in 88% (N-7) were positive on HPV of high risk. Patients with persistent ASCUS result were positive in 51% (N-19). The number of CIN I lesions found in women with ASCUS is bigger and statistically significant (p<0,05) in relation to number of CIN I findings found in regular examinations. CONCLUSION Monitoring women with ASCUS lesion, especially HPV positive to high risk group is the best way of selection of women who should be treated and monitored in order to prevent cervical cancer.

Abstract
This study investigates the distribution of human papillomavirus (HPV) in women with abnormal cervical cytology in Kuwait. Two hundred and ninety-eight (298) abnormal ThinPreps were taken from women seeking routine gynecological care and screened for HPV DNA by real-time PCR. HPV genotyping was determined by PCR-based sequencing. HPV DNA was detected in 152 women (51%), and 29 different HPV genotypes were detected, comprising 16 high-risk (HR) (16, 18, 31, 33, 35, 39, 45, 51, 53, 56, 58, 59, 66, 68, 73, 97), nine low-risk (LR) (6, 11, 54, 61, 74, 81, 90, 102, 106), and four intermediate-risk (IR) (62, 67, 84, 87). HPV16 had the highest prevalence (24.3%), followed by HPV11 (13.8%), HPV66 (11.2%), HPV33 (9.9%), HPV53 (9.2%), HPV81 (9.2%), HPV56 (7.9%) and HPV18 (6.6%). HPV prevalence was 86, 67, and 89% in women with invasive cervical carcinoma (ICC), high-grade squamous intraepithelial lesion (HSIL) and low-grade squamous intraepithelial lesion (LSIL), respectively. As for age distribution, 69% of all HPVs were found in women aged 20-29 years, and the HPV incidence rate deceased with increasing age. The proportion of single infections decreased as the severity of the cytological diagnosis increased, while the proportion of multiple infections increased. This study is the first of its type in Kuwait and one of few in the Middle East. The findings are consistent with the hypothesis that HPV infection is the primary cause of cervical neoplasia. They support HPV vaccine research to prevent cervical cancer and efforts to develop HPV DNA diagnostic tests.

Abstract
BACKGROUND High-risk (HR) human papillomavirus (HPV) prevalence rates, as determined by the Cervista(®) HPV HR test, in women aged ≥30 years in a routine screening population have not been studied. OBJECTIVES The primary objective of this study was to estimate HR HPV prevalence in women negative for intraepithelial lesion or malignancy (NILM) cytology using the CERVISTA HPV HR test. The study also compared HR HPV prevalence rates in women aged ≥30 years and NILM cytology using the CERVISTA HPV HR and Hybrid Capture(®) 2 (hc2) tests. STUDY DESIGN A multi-center study was conducted to analyze HR HPV prevalence rates using the CERVISTA HPV HR test from residual ThinPrep(®) specimens. HR HPV positive rates were determined for hc2; percent agreement between the CERVISTA HPV HR and the hc2 tests were reported. RESULTS HR HPV prevalence rates among women with NILM cytology were not statistically different between the CERVISTA HPV HR and hc2 tests (6.92% [98/1417] versus 5.93% [84/1417], respectively; P>0.05). The overall percent agreement between the tests was 95.3% (1351/1417; 95% confidence interval [CI]: 94.1-96.3; κ=0.61, 95% CI: 0.53-0.70). There were no statistically significant differences between tests across age groups or investigational sites. For both tests, there was a statistically significant decrease in HR HPV positive results as age increases (CERVISTA HPV HR, P=0.0009; hc2, P<0.0001). DISCUSSION There is no statistically significant difference between HR HPV prevalence rates obtained with the CERVISTA HPV HR and hc2 tests in women aged ≥30 years with NILM cytology.

Abstract
Aim: Human papillomavirus (HPV) detection is very important for the evaluation of prevention strategies in cervical cancer and other HPV-related diseases. This study aimed to assess the prevalence of high-risk HPV infection in a cohort of Qatari residents, and correlate this with cytology and potential risk factors. Method: The study utilized cervical cytology and HPV DNA testing methods, high-risk screen real-time PCR, to detect high-risk HPV genotype infections in a sample of Qatar’s female population. A series of 95 women attending the Gynecology/Oncology Clinic at Hamad Medical Corporation between August 2007 and May 2008 were enrolled in the study. Cervical smears isolated from patients were subjected to real-time PCR to confirm the presence of HPV DNA. The smears were characterized as atypical squamous cells of undetermined significance (ASCUS); low-grade squamous intraepithelial lesions (LGSIL) and high-grade squamous intraepithelial lesions (HGSIL). As a secondary outcome, risk factors for HPV infection were also assessed. However, the samples were not case-controlled for these. Results: A total of 28 women had normal smears and 65 had abnormal smears. Among the 65 women in the study population with abnormal smears, 33 had ASCUS (18 of them were HPV DNA positive), 21 had LGSIL (18 were HPV DNA positive), eight had HGSIL (four were HPV DNA positive) and the remaining three had squamous cell carcinoma (two were HPV DNA positive). Conclusion: The overall prevalence of high-risk HPV in our study population (n = 95) was 64%. The relatively high prevalence of HPV 52, 56 and 16 among the study group has important implications in vaccine prophylaxis in Qatar.

Abstract
Communication of equivocal findings and their significance has been a significant challenge related to Pap testing throughout its history. Terminology to report these findings has changed considerably to accommodate the changes in understanding of cervical neoplasia, and to accommodate new management strategies, tests, and technologies. This article reviews the evolution of terminology for equivocal Pap test findings from the original Papanicolaou classification to the current the Bethesda System 2001 atypical squamous cells terminology, the implication and use of these terms, and the changing landscape of cervical neoplasia screening, which prompted these terminology changes. Emerging issues related to improving risk stratification through the introduction of additional terms and the impact of human papillomavirus testing may alter terminology of equivocal findings in the future.

Abstract
In the American Society for Colposcopy and Cervical Pathology 2006 Consensus Guidelines, several changes in the management of mildly abnormal cervical cytology and histology were made. The most notable changes involve the management of adolescents, pregnant women, and postmenopausal women. For adolescents, management of atypical squamous cells of undetermined significance and low-grade squamous intraepithelial lesions is conservative, eliminating the need for immediate colposcopy. For pregnant women, options have been made to allow for deferral of colposcopy until pregnancy completion, whereas for postmenopausal women, the new guidelines call for the option to rely on human papillomavirus DNA testing or repeat cytology to manage mild cytologic abnormalities. The guidelines for cervical intraepithelial neoplasia 1 now focus on conservative management. The goal of this article is to review the 2006 Guidelines, elaborating on the changes and providing the rationale for management decisions.

Abstract
OBJECTIVE The objective of this study was to determine the risk of a clinically significant lesion associated with the diagnosis of atypical squamous cells-cannot exclude high-grade squamous intraepithelial lesion (ASC-H) on cervical cytology (Pap smear). METHODS This was a retrospective, observational, descriptive study. A computerized database containing cytologic and histologic information for the health region was used to identify women with a diagnosis of ASC-H on a Pap smear performed between January 1 and December 31, 2002. All pertinent pathology data (cytopathology, histopathology, and surgical specimens) were examined. Patients were excluded if they had a diagnosis of cervical cancer, adenocarcinoma in situ (AIS), or high-grade squamous intraepithelial lesion (HSIL) prior to the index Pap smear. RESULTS During the study period, 727 of 241 841 Pap smears (0.3%) were reported as ASC-H in 655 patients. Ninety-one patients had a previous diagnosis of cervical cancer, AIS, or HSIL and were excluded from analysis, and 12 patients on review did not have ASC-H. There were no follow-up data for 35 of the remaining 552 patients, leaving 517 patients in the study group. In this group, the rates of histologically proven cervical lesions were 2.9% (15/517) for cervical cancer, 1.7% (9/517) for AIS, and 65.6% (339/517) for HSIL. Women undergoing a procedure that included histological examination were more likely to have a significant lesion discovered. CONCLUSION The diagnosis of ASC-H on Pap smear is associated with an appreciable risk of clinically significant disease. Patients with an ASC-H Pap smear result should undergo timely colposcopic and histologic assessment to rule out HSIL, AIS, and cervical cancer.

Abstract
Data are beginning to accrue on high-risk HPV DNA testing in patients with ASC-US on cervical cytology. We report on our experience at the University of Wisconsin Hospital and Clinics. From February 2002 through December 31, 2005 (3 yr, 11 mo), the cytopathology laboratory processed 49,599 Pap Tests, of which 1,792 (3.6%) were diagnosed as ASC-US. Six hundred and seventy two (37.5%) of these cases were processed for high-risk HPV genotypes using the Digene Hybrid Capture II method. Of these cases, 266 (39.6%) were positive for high-risk HPV genotypes, 11 (1.6%) were equivocal, and 395 (58.8%) were negative. Biopsy follow-up was available for 127 (47.7%) of the 266 cases, of which 66 (52%) were negative, 46 (36.2%) showed CIN I, 9 (7.1%) were CIN II, and 6 (4.7%) were CIN III. Of the remaining 139 (52.3%) cases, 86 (62%) had follow-up Pap Tests, of which 57 (66.3%) were negative, 15 (17.4%) were ASC-US, 12 (15%) were low-grade squamous intraepithelial lesions, and 2 (2.3%) were high-grade squamous intraepithelial lesions; 53 (38.1%) were lost to follow-up. In combination, 90 (42.25%) of the 213 cases with follow-up showed atypia or above after a diagnosis of ASC-US; of which 58 (64%) were low-grade lesions and 17 (19%) were high-grade lesions. Our laboratory's reported high-risk HPV positivity is comparable to recent reports in the literature on its use in daily clinical practice. In addition, cervical abnormalities were found in a significant proportion of the cases.

Abstract
BACKGROUND The degree of applicability of the Bethesda System 2001 (TBS 2001) for cervicovaginal cytology to a public health setting is unknown, and extrapolations from available data are unwarranted. METHODS A "before/after" study design was used to evaluate the impact of TBS 2001 on an organized, population-based screening program in northern Italy. Between 2003-2004, 6 cytology laboratories converted from TBS 1991 to TBS 2001. A set of screening indicators based on TBS 2001 (85,012 patients) were compared with those based on TBS 1991 (199,833 patients) by means of their laboratory- and patient age-standardized ratio with a 95% confidence interval (CI). RESULTS The prevalence of cervical intraepithelial neoplasm (CIN)2-3/carcinoma was stable between the 2 populations. TBS 2001 had no effect on the unsatisfactory rate (1.99% vs. 2.03% for TBS 1991) nor on follow-up compliance rate (93.2% vs. 92.3%). The reporting rate of atypical squamous cells (ASC) decreased from 17.1 to 14.7 per 1000 (ratio, 0.86; 95% CI, 0.81-0.91), the total positivity rate from 31.1 to 29.0 per 1000 (ratio, 0.93; 95% CI, 0.90-0.97), and the ASC:SIL (squamous intraepithelial lesion) ratio from 1.38 to 1.16. Compared with the ASCUS (ASC of undetermined significance) reports of TBS 1991, the predictive value for CIN2-3/carcinoma decreased from 5.2 to 3.5% (ratio, 0.68; 95% CI, 0.48-0.93) among ASCUS reports, but increased from 5.1 to 17.2% (ratio, 3.41; 95% CI, 1.64-6.28) among ASC-cannot exclude high grade lesion (ASC-H) reports. ASC-H had a 5.01-fold (95% CI, 2.23-10.2) greater predictive value than ASCUS. CONCLUSIONS TBS 2001 is applicable to cervical screening in a public health setting.

Abstract
OBJECTIVE The American Society for Colposcopy and Cervical Pathology (ASCCP) guidelines for management of ASC-H is colposcopic examination followed by biopsy. HPV testing (HPVT) is recommended after a negative biopsy result. More definitive interpretation of ASC-H could prevent discomfort and minimize the cost. The purpose of this study was to evaluate association of various cytomorphological patterns of ASC-H with various clinical scenarios. METHODS We reviewed SurePath (TriPath Imaging, Inc. Burlington, NC, USA) cervical smears interpreted as ASC-H in 161 women (mean age, 37 {15 to 78} years), over 24 months (2002 to 2003). HPVT (Digene, Hybrid Capture II HPV test, Digene Corporation, Gaithersburg, MD, USA) was performed in 20% of cases (33/161) and biopsy results were available in 54 cases (19 with and 35 without HPVT). RESULTS HPVT was positive in 64% (21/33) cases, and negative in 36% (12/33) cases. In the follow-up biopsies of 71% (15/21) of cases with positive HPVT, 27% showed HPV changes or CIN1, 27% showed CIN2-3, and 46% were negative for epithelial abnormality. Follow-up biopsies from cases with negative HPVT (33%, 4/12 cases), 8% showed CIN1 and 25% were negative for any epithelial abnormality. Six cytomorphological patterns of ASC-H correlated with different clinical categories in relation to HPVT and biopsy results. 35% (19 out of 54 ASC-H cases in which biopsy results were available) could be interpreted definitively as HSIL by cytopathology, 11% (6/54) cases as LSIL with cyanophilic atypical parakeratotic pattern, and 31% (17/54) cases as reactive, with HPV status. The interpretation had to be continued as ASC-H in 22% (12/54) cases. CONCLUSION ASC-H demonstrated a spectrum of cytomorphological patterns. Some of these patterns in liquid-based cervical smears may be more specifically interpreted as LSIL, HSIL, or benign if HPV status is known.

Abstract
A report of ASCUS is always confusing or painful to the clinician, as histological correlate of this diagnosis is wide, ranging from a totally normal cervix mucosa to infiltrating carcinoma; most of the time it is the result of benign inflammatory or reactive changes. This is the reason why this category has evolved since its introduction in the Bethesda system for reporting cervical cytology in 1988, to achieve a closer link to the lesional diagnosis. The most recent modification took place in 2001, to subcategorize the ASC into ASC-US and ASC-H. The present review provides guidelines to manage these diagnoses.

Abstract
The role of human papillomavirus (HPV) in cases diagnosed as atypical squamous cells, cannot exclude high squamous grade intraepithelial lesion (ASC-H) in cervical specimens is not well established. The objective of this study is to evaluate the role of HPV status in cases of ASC-H in a major cancer center. One hundred thirty-two patients with a diagnosis of ASC-H were identified over a 4-yr period in our institution. Forty-four of 132 cases were evaluated for high-risk HPV and had biopsy follow-up. The positive predictive value (PPV) of ASC-H for high-grade squamous intraepithelial lesions overall was 32% while PPV of ASC-H with associated HR HPV was 42%. This increase was statistically significant with P = 0.003 and suggest that HPV testing might be useful to increase the PPV of ASC-H.

Abstract
This study is aimed to investigate the role of reflex high-risk human papilloma virus (HPV) DNA testing as an alternative triage method to colposcopy for women with atypical squamous cells cannot exclude high-grade squamous intraepithelial lesion (ASC-H) on Papanicolaou (Pap) tests. Reflex HPV DNA testing using Hybrid Capture II method was carried out on 88 women with ASC-H diagnosed by Thin Prep Pap test. Correlation with follow-up biopsies was available on 42 of these patients. The reflex HPV DNA test showed an overall positive rate of 67% and negative rate of 33% in 88 patients with ASC-H. Using age 30 as the cut off point, the positive rate had increased to 83.3% (35/42) in patients 30 yr or younger, while the positive rate for patients older than 30 yr had decreased to 52.2% (24/46). Follow-up colposcopic biopsy results were available in 35 of 59 HPV-positive women, which revealed 15 (43%) high-grade squamous intraepithelial lesions (HSIL), 12 low-grade squamous intraepithelial lesions (LSIL), and 8 negative for dysplasia. In 7 HPV-negative patients, the follow-up biopsies showed no evidence of HSIL or LSIL. Correlation between clinical risk factors and the HPV results demonstrated no significant differences in HPV positivity between the high-risk and low-risk patients. The high sensitivity (100%) and negative predictive rate (100%) in detecting HSIL in our study provide strong evidence that, instead of automatic referral to colposcopy, reflex HPV DNA testing may be used as an alternative triage method for women diagnosed with ASC-H on Thin Prep Pap test, especially for women older than 30 yr of age.

[PMID: 16290002 DOI: 10.1016/j.ygyno.2005.09.050] [Citation(s) in RCA: 15] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2005] [Revised: 09/12/2005] [Accepted: 09/22/2005] [Indexed: 11/23/2022]
Abstract
OBJECTIVE To determine the prevalence of HR-HPV DNA in ASC-US Pap smears following implementation of the Bethesda 2001 classification system. METHODS A computer database of Pap smears obtained within Department of the Army medical facilities was queried for the study period August 2002 to June 2004. All ASC-US Pap smears that underwent reflex testing for HR-HPV DNA were included. Additional clinical and demographic data were obtained from facilities within the US northeast region to evaluate the differences in ASC-US and SIL rates between the current and former Bethesda classification systems. RESULTS 550,000 Pap smears were collected during the study period. The HR-HPV prevalence was 40.8% (95% confidence interval [CI] = 40.3 to 41.3) among 40,870 patients with ASC-US Pap smears. Within the northeast region, the HR-HPV prevalence in ASC-US Pap smears decreased from 61.2% (95% CI = 57.4 to 64.8%) in patients 18-22 years old to 24.9% (95% CI = 23.1 to 26.8%) in patients age 29 and older. When comparing the two classification systems, significant increases in both ASC-H and SIL and decreases in ASC-US were appreciated after the institution of Bethesda system 2001. CONCLUSION In our large, diverse cohort, the implementation of the Bethesda II system has resulted in a decrease in ASC-US Pap smear results. Additionally, the prevalence of HR-HPV in the ASC-US population was 40.8%, significantly lower than the rate noted in the ALTS trial under the Bethesda I classification system.

Abstract
We compared the overall ASC rate and the outcomes for women with different categories of ASC before and after TBS 2001 to evaluate the impact of TBS 2001. Our laboratory reported ASC in four subcategories before TBS 2001; ASC, favor reactive (ASC-R), favor low-grade squamous intraepithelial lesion (SIL) (ASC-L), undetermined significance (ASC-US), and ASC-H. Since the implementation of TBS 2001, we have been reporting ASC as ASC-US and ASC-H. After TBS 2001, our ASC rate decreased from 6.2% to 4% (P < 0.0001). Before TBS 2001, ASC-R carried the same risk as ASC-US for underlying condyloma/CIN 1. Moreover, ASC-R was rarely associated with CIN 2 or 3. Before TBS 2001, ASC-H captured more low-grade (condyloma/CIN 1) and less high-grade (CIN 2, 3, and SCC) lesions compared to after TBS 2001. More women with ASC-H after TBS 2001 underwent colposcopy (80% vs. 71%, P < 0.05). Twenty-two percent of women with ASC-H required 2-4 colposcopies to identify the high-grade lesion. Our results confirm that consistent application of TBS 2001 terminology for ASC reduces the ASC rate, and better identifies women at high risk for CIN 2, 3, and SCC. In addition, ASC-H requires very close clinical follow-up as a significant percentage of women require more than one colposcopy to identify the high-grade lesion.
