Abstract Background: High-risk human papillomavirus (HR-HPV) infection is widely known as the major cause of cervical intraepithelial neoplasia (CIN) and cervical cancer and it’s characteristics vary greatly in different population. Women with abnormal cervical cytology could increase the risk of cervical cancer, however, HR-HPV infection characteristics in women with abnormal cervical cytology remains unclear. Methods: This study was based on baseline survey of the CIN Cohort established in Shanxi Province, China. A total number of 2300 women with cervical abnormalities were enrolled in this study. All participants gave informed consent and agreed to HPV and thinprepcytologic test (TCT). Each individual completed a questionnaire about characteristics related to HPV infection. Results: The overall prevalence of HR-HPV in 2300 women was 32.0%, and the proportion of single and multiple HR-HPV infections were 70.2% and 29.8% in HR-HPV infection women, respectively. The top five HR-HPV genotypes were ranked as HPV16, HPV58, HPV52, HPV53 and HPV51. The prevalence of HR-HPV in atypical squamous cells of undetermined significance (ASC-US), low-grade squamous intraepithelial lesion (LSIL) and high-grade squamous intraepithelial lesion and above(HSIL+) were 30.8%, 36.5% and 54.9%, respectively, showing an increasing trend with the severity of cervical cytology ( χ 2 trend =13.952; p <0.001). The women aged 35~45 years, with lower education level, less frequency of bathing, multiple gravidity, multiple parity, history of gynecological diseases and premenopausal women were prone to HR-HPV infection. Conclusions: We defined the characteristics related to HR-HPV infection in abnormal cervical cytology women, and provided an insight for the development and deeply research of HPV vaccine.

Bethesda System

Context.— Cervical cancer screening laboratory practices may evolve with new terminology and technologies. Objective.— To investigate changes in cervical cytopathology practice resulting from the 2014 Bethesda System updates and screening technologies. Design.— Questionnaires accompanied 2016 and 2017 mailings of the College of American Pathologists PAP Education program. Results.— In 2016, most laboratories surveyed had adopted or were planning to adopt 2014 Bethesda System updates, and the majority (53%; 365 of 689) used an age cutoff of 45 for reporting benign-appearing endometrial cells. However, 51.3% (354 of 690) of laboratories used the term low-grade squamous intraepithelial lesion, cannot exclude high-grade squamous intraepithelial lesion, for cases with indeterminate features, and 44.9% (298 of 664) of laboratories used a 5000-cell cutoff for minimum squamous cellularity for posthysterectomy and posttherapy specimens. Reporting rates for cervical cytology metrics changed very little from 2013 to 2016, and the median ratio of atypical squamous cells to squamous intraepithelial lesion cases was 1.9 for ThinPrep and 1.8 for SurePath preparations. Most laboratories (59.4%; 389 of 655) did not offer stand-alone primary human papillomavirus (HPV) testing in 2017, and primary HPV testing accounted for a low proportion of HPV testing volumes. The Roche Cobas method was the most common platform for HPV primary screening. Conclusions.— These questionnaire surveys provide data about the current status of cervical cytology screening, including changes related to the 2014 Bethesda System updates and the adoption of HPV primary screening techniques.

Objective: This study evaluated the performance of a flow cytometry system (LC-1000) in screening cervical precancerous lesions at routine health checkups. Study design: In total, 928 health examinees were enrolled at 16 health promotion centers in 13 Korean cities between 2016 and 2017. All participants underwent liquid-based cervical cytology and flow cytometry testing to determine the cell proliferation index (CPIx). Results: The positivity rate of the LC-1000 system increased with the severity of the cervical cytology findings (p for trend < 0.001). When low-grade squamous intraepithelial lesion (LSIL) or higher (including LSIL, high-grade squamous intraepithelial lesion [HSIL], and atypical squamous cells without excluding HSIL [ASC-H]) was defined as gold-standard positivity, the sensitivity, specificity, PPV, and NPV of LC-1000 were 75.3% (95% confidence interval [CI], 66.8–83.7), 58.5% (95% CI, 55.2–61.9), 18.1% (95% CI, 14.5–21.8), and 95.1% [95% CI, 93.2–97.0], respectively. The median CPIx increased significantly from normal cytology to HSIL (p < 0.001). The median CPIx was higher in high-risk human papillomavirus (HR-HPV)-positive cases than in HR-HPV-negative cases (0.23 vs. 0.17, p < 0.001), while it did not differ between HR-HPV-positive and HR-HPV-negative cases with normal cytology findings (0.16 vs. 0.16, p = 0.700). Conclusion: The LC-1000 system is potentially useful for screening cervical precancer and cancer, especially when excluding normal or ASC of undetermined significance cases in routinely screened populations.

Introduction: Cervical cancer is a common health problem in Nepal. There is paucity of data regarding the spectrum of findings in cervical Pap in western Nepal. This study was aimed to study the cytological patterns in cervical Pap smears in patients in a tertiary hospital of Nepal. Methods: This is a prospective, cross sectional, hospital based study. Clinical features of patients who had presented with Pap smear was noted in a structured proforma. Pap smears were studied by a senior pathologist and reported based on revised Bethesda system (2014). Results: Most of the cases belonged to 31-40 years 399 (42.8%). Unsatisfactory/ inadequate sample was present in 133(14.05%) with obscuration due to inflammatory exudate being most common cause. Negative for intraepithelial lesion or malignancy rate was noted in 798 (85.54%) with 477(51.2%) being normal findings. Epithelial cell abnormalities were noted in 116 (14.5 %) smears. Low-grade squamous intraepithelial lesion constituted 321(34.5%), High grade squamous intraepithelial lesion 273(29.3 %) and Atypical squamous cells of undetermined significance 153(16.4%) of epithelial cell abnormalities. Squamous cell carcinoma was present in 9(1%) of all reviewed smears. There was no statistical significance between the age and abnormalities of Pap smear (p=0.9). Conclusions: Pap smear is pivotal in cervical cancer screening in developing countries. It also identifies various inflammatory, infective, benign and malignant pathologies at the earliest thereby decreasing the morbidity and mortality.

A Prospective Study

Background: Cervical cancer is a leading cause of mortality and morbidity among women worldwide and most common gynaecological cancer in developing countries. Papanicolaou smear is a simple and cost effective screening test for cervical cancer. The aim of this study is to evaluate and interpret the cervical pap smear cytology in a tertiary hospital. The interpretation and reporting of the pap smear is based on 2001Bethesda system.Materials and methods: This is a prospective study conducted in a tertiary hospital, Nepal Medical College over a period of two and a half years (January 2013 to June 2015). All cervical pap smears received in the department of Pathology in the study period were included.Results: A total of 4160 cervical pap smears were reported in the study period. Majority of the cases were Negative for Intraepithelial lesion or malignancy (87.9%). Bacterial vaginosis, atrophy and reactive cellular changes associated with inflammation were seen in 5.3%, 2.4% and 1.5% cases respectively.   Epithelial cell abnormalities (0.5%) include Atypical squamous cells of undetermined significance, Low grade squamous intraepithelial lesion and High grade intraepithelial lesion. 88% of Low grade squamous intraepithelial lesion was seen in reproductive age group (20-45 years).Conclusion: Cervical cancer is the most common gynaecological cancer in the developing countries. Pap smear is the simple and cost effective screening tool to detect pre invasive cervical epithelial lesions.

CONTEXT AND OBJECTIVE: Cervical cancer is a serious public health problem in Brazil. For patients with unsatisfactory colposcopic examinations without visible lesions, but with cervical cytological tests suggesting high-grade squamous intraepithelial lesion (HSIL), the national recommendation is to repeat cervical cytological tests after three months. Our aim was to assess the prevalence of HSIL and cancer among patients with initial cervical cytological tests suggestive of HSIL but with unsatisfactory colposcopic examinations without visible lesions, in order to contribute towards the discussion regarding a more effective clinical approach that might diminish the likelihood of patient abandonment of follow-up before appropriate diagnosis and treatment. DESIGN AND SETTING: Cross-sectional study in Colposcopy Clinic of IFF/Fiocruz. METHOD: Patients admitted between December 1989 and April 2007 with cytological diagnoses of HSIL but with unsatisfactory colposcopic examinations without visible lesions underwent cervical cone biopsy. RESULTS: Sixty-five such patients were included, comprising 33.8% with HSIL and 4.6% with cancer, confirmed histologically. The other patients presented low-grade squamous intraepithelial lesion (26.1%), glandular dysplasia (1.5%) and absence of disease (33.8%). CONCLUSION: The observed prevalence of cancer and HSIL does not seem to be enough to justify immediate referral for cone biopsies to investigate the cervical canal in these cases. The findings suggest that the recommendation of repeated cytological tests following an initial one with HSIL, among patients with unsatisfactory colposcopic examinations without visible lesions, is appropriate in our setting. Efforts are needed to ensure adherence to follow-up protocols in order to reduce the chances of losses.

Reporting Rates

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.

Background: p16 INK4a (p16) is a well-recognized surrogate molecular marker for human papilloma virus (HPV) related squamous dysplasia. Our hypothesis is that the invasive interventions and related morbidities could be avoided by objective stratification of positive cytologic interpretations by p16 immunostaining of cell block sections of cytology specimens. Materials and Methods: Nuclear immunoreactivity for p16 was evaluated in cell block sections in 133 adequate cases [20 negative for intraepithelial lesion or malignancy, 28 high-grade squamous intraepithelial lesion (HSIL), 50 low-grade squamous intraepithelial lesion (LSIL), 21 atypical squamous cells, cannot exclude HSIL (ASC-H), and 14 atypical squamous cells of undetermined significance (ASCUS)] and analyzed with cervical biopsy results. Results: (a) HSIL cytology (28): 21 (75%) were p16 positive (11 biopsies available — 92% were positive for cervical intraepithelial neoplasia (CIN) 1 and above) and 7 (25%) were p16 negative (3 biopsies available — all showed only HPV with small atypical parakeratotic cells). (b) LSIL cytology (50): 13 (26%) cases were p16 positive (12 biopsies available — all were CIN1 or above) and 37 (74%) were p16 negative (12 biopsies available — all negative for dysplasia. However, 9 (75%) of these biopsies showed HPV). (c) ASC-H cytology (21): 14 (67%) were p16 positive (6 biopsies available — 5 showed CIN 3/Carcinoma in situ/Ca and 1 showed CIN 1 with possibility of under-sampling. Cytomorphologic re-review favored HSIL) and 7 (33%) were p16 negative (5 biopsies available — 3 negative for dysplasia. Remaining 2 cases — 1 positive for CIN 3 and 1 showed CIN 1 with scant ASC-H cells on cytomorphologic re-review with possibility under-sampling in cytology specimen). (d) ASCUS cytology (14): All (100%) were p16 negative on cell block sections of cervical cytology specimen. HPV testing performed in last 6 months in 7 cases was positive in 3 (43%) cases. Conclusion: p16 immunostaining on cell block sections of cervical cytology specimens showed distinct correlation patterns with biopsy results. Reflex p16 immunostaining of cell blocks based on the algorithmic approach to be evaluated by a multiinstitutional comprehensive prospective study is proposed.
