Abstract
Objectives Atypical squamous cells of undetermined significance (ASC-US) represent a diagnostic challenge during cervical cytology. This study aimed to review and identify high-risk human papillomavirus (HR-HPV) genotypes among previously diagnosed ASC-US cases in Kuwait. Methods This retrospective study analysed 180 cases diagnosed as ASC-US between June 2017 and May 2018 at the Mubarak Al-Kabeer Hospital, Kuwait. Cervical specimens were assayed to determine the presence of HR-HPV DNA; subsequently, positive cases underwent genotyping and were categorised into three groups (HPV 16, HPV 18/45 and other HR-HPV types). Results In total, ASC-US was confirmed in only 105 cases (58.3%), with the remaining cases reclassified as negative for intraepithelial lesions or malignancy (NILM; 32.2%) and epithelial cell abnormalities (ECA; 9.4%). Of these, HR-HPV DNA was present in 20 ASC-US (19%), one NILM (1.7%) and six ECA (35.3%) cases. There were 62 Kuwaiti and 43 non-Kuwaiti women with confirmed ASC-US; of these, three (4.8%), six (9.7%) and four (6.5%) Kuwaitis and one (2.3%), one (2.3%) and five (11.6%) non-Kuwaitis had HPV 16, both HPV 16 and 18/45 and other HR-HPV genotypes, respectively. Of those with HR-HPV DNA, the NILM case had the HPV 18/45 genotype, while the six ECA cases had the HPV 16 (n = 1), both HPV 16 and 18/45 (n = 1) and other HR-HPV (n = 4) genotypes. Conclusion Overall, HR-HPV DNA was present in 19% of ASC-US cases compared to 1.7% of NILM cases initially misdiagnosed as ASC-US. Re-review of cervical cytology diagnoses may reduce unnecessary costs associated with HR-HPV genotyping.

[PMID: 33061708 PMCID: PMC7522426 DOI: 10.2147/rmhp.s270265] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2020] [Accepted: 08/13/2020] [Indexed: 01/01/2023] Open
Abstract
Purpose Little is known about the performance of extended high-risk human papillomavirus (HR-HPV) genotyping triage of cytology showing atypical squamous cells of undetermined significance (ASC-US). This study aims to evaluate the effectiveness of triage with different HR-HPV genotype models among women with ASC-US. Materials and Methods In this study, all women who underwent cervical cytology and HR-HPV genotyping were enrolled from 2014 to 2017 in China, and those with cytology showing ASC-US were referred for colposcopy and/or biopsy. The endpoint was histological detection of cervical intraepithelial neoplasia grade 2 or worse (CIN2+). The outcome indicators were the sensitivity, specificity, positive predictive values (PPVs), negative predictive values (NPVs) and colposcopy referral rates. Results In all, 56,788 women were enrolled in this study, and 2658 (4.97%) women were reported to have ASC-US; 10.1% (242/2393) of women with ASC-US were identified as having CIN2+. The HR-HPV infection rate was 95.0% among all women with ASC-US who were identified as CIN2+, and the top five genotypes with prevalence and risk of CIN2+ were HPV16 (OR=26.38), HPV58 (OR=7.04), HPV18 (OR=4.44), HPV33 (OR=3.38), HPV31 (OR=2.97) and HPV52 (OR=2.96). The HPV16/18/31/33/52/58 model achieved higher sensitivity [91.3 (87.8-94.9)], specificity [70.0 (68.1-72.0)], PPV [25.5 (22.4-28.2)] and NPV [98.6 (97.3-98.7)] for the triage of ASC-US patients than the other HR-HPV-type combination models, but the colposcopy referral rate (36.2%) was significantly lower than that of the recommended HR-HPV nongenotyping model (47.6%). Conclusion This study confirms that the specific HR-HPV genotype HPV16/18/31/33/52/58 is an alternative strategy for ASC-US triage and can effectively reduce the high burden of colposcopy referrals in China.

Abstract
Purpose To evaluate the performance of different high-risk human papillomavirus (HR-HPV) genotype models in triaging women with cytological diagnosis of atypical squamous cells of undetermined significance (ASCUS). Patients and Methods A total of 36,679 Chinese women who underwent cytology and HR-HPV genotyping assessments during cervical cancer screening were enrolled in this study. Women with cytology-proven ASCUS were referred for further screening by colposcopy and biopsy. The study endpoint was histological detection of cervical intraepithelial neoplasia grade 2 or worse (CIN2+) at any of the follow-up visits. The sensitivity, specificity, positive predictive values (PPVs), negative predictive values (NPVs), positive likelihood ratio (PLR) and negative likelihood ratio (NLR) of different HR-HPV genotype combination models were estimated. Results In all, 1675 (4.9%) women were identified as having ASCUS, 1454 women underwent colposcopy and biopsy, and 6.0% (87/1454) women were identified as having CIN2+ lesions. Among those with ASCUS who were identified as having CIN2+, the HR-HPV infection rate was 97.7%, and the prevalence rates of HPV-16, −18, −31, −33, −35, −39, −45, −51, −52, −56, −58, −59, −66 and −68 were 48.3%, 8.0%, 6.9%, 4.6%, 1.1%, 2.3%, 3.4%, 3.4%, 26.4%, 1.1%, 17.2%, 2.3%, 0.0% and 0.0%, respectively. Compared to other HR-HPV-type combination models, the HPV16/18/31/33/52/58 model achieved a higher sensitivity [93.1 (87.8–98.4)], specificity [73.0 (70.7–75.4)], PPV [18.0 (14.5–21.5)], NPV [99.4 (98.9–99.9)], PLR [3.7 (3.1–3.8)] and NLR [0.06 (0.03–0.18)] for the triage of ASCUS patients, but the colposcopy referral rate (30.9%) was significantly lower than that of the recommended HR-HPV model (44.0%). Conclusion This study confirms that the specific HR-HPV genotype HPV16/18/31/33/52/58 is an alternative strategy for ASCUS triage and can effectively reduce the high burden of colposcopy referrals in China.

Abstract
Background Although it is well acknowledged that persistent infection with high-risk human papillomavirus types in genital sites plays a crucial role in the development of squamous cell cervical carcinoma, there is no unanimous consensus on the association between non-HPV sexually transmitted infections and abnormal cervical cytology. Methods In the present study, we evaluated cervical cytology status, sexually transmitted infections and bacterial vaginosis status, and collected social-demographic information among recruited participants to explore the association of STIs and bacterial vaginosis with abnormal cervical cytology. Results 9,090 women’s specimens were successfully tested, with a total of 8,733 (96.1%) women had normal cytology and 357 (3.9%) women exhibited abnormal cytology. The prevalence of HPV, Chlamydia trachomatis, Neisseria gonorrhoeae, and bacterial vaginosis was significantly higher in the ≥ASC-US group than the NILM group (P<0.05). Women with Neisseria gonorrhoeae infection (AOR = 5.30, 95% CIs = 1.30–21.51, P = 0.020) or bacterial vaginosis (AOR = 1.94, 95% CIs = 1.08–3.47, P = 0.026) exhibited an increased risk of abnormal cervical cytology after adjusted for carcinogenic HPV-positive status. Conclusions Our results demonstrated that Neisseria gonorrhoeae infection in genital sites and/or bacterial vaginosis may independently increase the risk for cervical cytology abnormalities after adjusted for carcinogenic HPV-positive status. Besides, these results improved our understanding of the etiology of abnormal cervical cytology and may be useful for the management of women with ASC-US cytology.

Abstract
Objective: The purpose of this study was to evaluate the effect of different combination models of high-risk human papilloma viruses (HPV) genotyping in triaging Chinese women with atypical squamous cells of undetermined significance (ASCUS). Methods: We established a screening cohort of 3,997 Chinese women who underwent cervical cytology and HPV genotyping test. Women with ASCUS cytology underwent punch biopsy under colposcopy/endocervical curettage. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of different combination models of HR-HPV genotyping calculated that cervical intraepithelial neoplasia 2 or higher (CIN2+) on histology were endpoints. Results: Of the full sample, 393 women had ASCUS. Among ASCUS women with a CIN2 lesion, the prevalence for HPV were 40.0% (type 16), 10.0% (type 18), 0.0% (type 33), 30.0% (type 52), 40.0% (type 58), and 30.0% (other nine types). For ASCUS women with a CIN3 lesion, the prevalence for HPV were 68.4% (type 16), 15.8% (type 18), 10.5% (type 33), 31.6% (type 52), 15.8% (type 58), and 36.8% (other nine types). Combination model including HPV16/18/33/52/58 for predicting CIN2+ lesion in women with ASCUS had relatively higher sensitivity [93.1% (78.0, 98.1)], specificity [75.8% (71.2, 79.9)], PPV [23.5% (16.7, 32.0)], and NPV [99.3% (97.4, 99.8)] than other combination models. Moreover, the referral rate of HPV16/18/33/52/58 (29.3%) was lower than HR-HPV (36.1%). Conclusions: The study demonstrates that specific HR-HPV types HPV16/18/33/52/58 may be an effective strategy in ASCUS triage. This improves the subsequent selection of ASCUS patients.

Abstract
BACKGROUND Atypical squamous cells of undetermined significance (ASCUS) and low-grade squamous intra-epithelial lesions (LSIL) are minor lesions of the cervical epithelium, detectable by cytological examination of cells collected from the surface of the cervix of a woman.Usually, women with ASCUS and LSIL do not have cervical (pre-) cancer, however a substantial proportion of them do have underlying high-grade cervical intra-epithelial neoplasia (CIN, grade 2 or 3) and so are at increased risk for developing cervical cancer. Therefore, accurate triage of women with ASCUS or LSIL is required to identify those who need further management.This review evaluates two ways to triage women with ASCUS or LSIL: repeating the cytological test, and DNA testing for high-risk types of the human papillomavirus (hrHPV) - the main causal factor of cervical cancer. OBJECTIVES Main objective To compare the accuracy of hrHPV testing with the Hybrid Capture 2 (HC2) assay against that of repeat cytology for detection of underlying cervical intraepithelial neoplasia of grade 2 or worse (CIN2+) or grade 3 or worse (CIN3+) in women with ASCUS or LSIL. For the HC2 assay, a positive result was defined as proposed by the manufacturer. For repeat cytology, different cut-offs were used to define positivity: Atypical squamous cells of undetermined significance or worse (ASCUS+), low-grade squamous intra-epithelial lesions or worse (LSIL+) or high-grade squamous intra-epithelial lesions or worse (HSIL+).Secondary objective To assess the accuracy of the HC2 assay to detect CIN2+ or CIN3+ in women with ASCUS or LSIL in a larger group of reports of studies that applied hrHPV testing and the reference standard (coloscopy and biopsy), irrespective whether or not repeat cytology was done. SEARCH METHODS We made a comprehensive literature search that included the Cochrane Register of Diagnostic Test Accuracy Studies; the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library), MEDLINE (through PubMed), and EMBASE (last search 6 January 2011). Selected journals likely to contain relevant papers were handsearched from 1992 to 2010 (December). We also searched CERVIX, the bibliographic database of the Unit of Cancer Epidemiology at the Scientific Institute of Public Health (Brussels, Belgium) which contains more than 20,000 references on cervical cancer.More recent searches, up to December 2012, targeted reports on the accuracy of triage of ASCUS or LSIL with other HPV DNA assays, or HPV RNA assays and other molecular markers. These searches will be used for new Cochrane reviews as well as for updates of the current review. SELECTION CRITERIA Studies eligible for inclusion in the review had to include: women presenting with a cervical cytology result of ASCUS or LSIL, who had undergone both HC2 testing and repeat cytology, or HC2 testing alone, and were subsequently subjected to reference standard verification with colposcopy and colposcopy-directed biopsies for histologic verification. DATA COLLECTION AND ANALYSIS The review authors independently extracted data from the selected studies, and obtained additional data from report authors.Two groups of meta-analyses were performed: group I concerned triage of women with ASCUS, group II concerned women with LSIL. The bivariate model (METADAS-macro in SAS) was used to assess the absolute accuracy of the triage tests in both groups as well as the differences in accuracy between the triage tests. MAIN RESULTS The pooled sensitivity of HC2 was significantly higher than that of repeat cytology at cut-off ASCUS+ to detect CIN2+ in both triage of ASCUS and LSIL (relative sensitivity of 1.27 (95% CI 1.16 to 1.39; P value < 0.0001) and 1.23 (95% CI 1.06 to 1.4; P value 0.007), respectively. In ASCUS triage, the pooled specificity of the triage methods did not differ significantly from each other (relative specificity: 0.99 (95% CI 0.97 to 1.03; P value 0.98)). However, the specificity of HC2 was substantially, and significantly, lower than that of repeat cytology in the triage of LSIL (relative specificity: 0.66 (95% CI 0.58 to 0.75) P value < 0.0001). AUTHORS' CONCLUSIONS HPV-triage with HC2 can be recommended to triage women with ASCUS because it has higher accuracy (significantly higher sensitivity, and similar specificity) than repeat cytology. When triaging women with LSIL, an HC2 test yields a significantly higher sensitivity, but a significantly lower specificity, compared to a repeat cytology. Therefore, practice recommendations for management of women with LSIL should be balanced, taking local circumstances into account.

Abstract
Limited follow-up data are available on patients with cervical cytology results of atypical squamous cells, cannot exclude a high-grade intraepithelial lesion (ASC-H), who test negative for high-risk human papillomavirus (hrHPV). Between June 2005 and December 2010, 885 patients were identified with ThinPrep results of Hybrid Capture 2 (HC2) hrHPV-negative cervical ASC-H liquid-based cytology and follow-up histopathology or cytology results extending to September 2011. Of the 885 patients with available follow-up results, 549 (62.0%) had at least 1 histopathologic result during the entire follow-up period, whereas 336 (38.0%) had only cytologic follow-up documented. In an average follow-up period of 29 months, 14 (1.6%) of 885 patients with HPV-negative ASC-H results showed evidence of high-grade cervical intraepithelial neoplasia (CIN2/3). No cases of invasive cervical cancer were diagnosed. Four of 14 patients with HPV-negative ASC-H results with follow-up diagnoses of CIN2/3 had a history of earlier CIN2/3 diagnoses before HPV-negative ASC-H results. Follow-up of patients with HPV-negative ASC-H results using methods specified in this study yielded low rates of detectible CIN2/3 and no diagnoses of cervical cancer. Triage of study patients with HPV-negative ASC-H results to routine HPV and cytology cotesting at 1 year was a safe follow-up option.

Abstract
Introduction. To analyze patients with atypical squamous cells of undetermined significance (ASCUS) through a cytology review and the presence of microbiological agents, with consideration of colposcopy and semiannual tracking. Methods. 103 women with ASCUS were reviewed and reclassified: normal/inflammatory, ASCUS, low-grade squamous intraepithelial lesion (LSIL), or high-grade squamous intraepithelial lesion (HSIL). If ASCUS confirmed, it was subclassified in reactive or neoplastic ASCUS, ASC-US, or ASC-H; and Regione Emilia Romagna Screening Protocol. Patients underwent a colposcopic examination, and test for Candida sp., bacterial vaginosis, Trichomonas vaginalis, and human papillomavirus (HPV) were performed. Results. Upon review, ASCUS was diagnosis in 70/103 (67.9%), being 38 (54.2%) reactive ASCUS and 32 (45.71%) neoplastic ASCUS; 62 (88.5%) ASC-US and 8 (11.41%) ASC-H. ASCUS (Regione Protocol), respectively 1-5: 15 (21.4%), 19 (27.1%), 3 (27.1%), 16 (22.8%), and 1 (1.4%). A higher number of cases of cervical intraepithelial neoplasia (CIN) II/III in the biopsies of patients with ASC-H compared to ASC-US (P = .0021). High-risk HPV test and presence of CIN II/III are more frequent in ASC-H than ASC-US (P = .031). Conclusions. ASC-H is associated with clinically significant disease. High-risk HPV-positive status in the triage for colposcopy of patients with ASC-US is associated with increased of CIN.

Abstract
CONTEXT AND OBJECTIVE The latest update of the Bethesda System divided the category of atypical squamous cells of undetermined significance (ASCUS) into ASC-US (undetermined significance) and ASC-H (high-grade intraepithelial lesion cannot be ruled out). The aims here were to measure the prevalence of pre-invasive lesions (cervical intraepithelial neoplasia, CIN II/III) and cervical cancer among patients referred to Instituto Fernandes Figueira (IFF) with ASC-H cytology, and compare them with ASC-US cases. DESIGN AND SETTING Cross-sectional study with retrospective data collection, at the IFF Cervical Pathology outpatient clinic. METHODS ASCUS cases referred to IFF from November 1997 to September 2007 were reviewed according to the 2001 Bethesda System to reach cytological consensus. The resulting ASC-H and ASC-US cases, along with new cases, were analyzed relative to the outcome of interest. The histological diagnosis (or cytocolposcopic follow-up in cases without such diagnosis) was taken as the gold standard. RESULTS The prevalence of CIN II/III in cases with ASC-H cytology was 19.29% (95% confidence interval, CI, 9.05-29.55%) and the risk of these lesions was greater among patients with ASC-H than with ASC-US cytology (prevalence ratio, PR, 10.42; 95% CI, 2.39-45.47; P = 0.0000764). Pre-invasive lesions were more frequently found in patients under 50 years of age with ASC-H cytology (PR, 2.67; 95% CI, 0.38-18.83); P = 0.2786998). There were no uterine cervical cancer cases. CONCLUSION The prevalence of CIN II/III in patients with ASC-H cytology was significantly higher than with ASC-US, and division into ASC diagnostic subcategories had good capacity for discriminating the presence of pre-invasive lesions.

Abstract
BACKGROUND Current guidelines recommend colposcopy rather than high-risk human papillomavirus (HPV) testing for the evaluation of abnormal cervical cytology interpreted as "atypical squamous cells, cannot exclude high-grade squamous intraepithelial lesion" (ASC-H) based on data from the Atypical Squamous Cells of Undetermined Significance/Low-Grade Squamous Intraepithelial Lesion (ASCUS/LSIL) Triage Study (ALTS), which indicated that ASC-H had a significantly greater frequency of high-risk HPV positivity and underlying high-grade squamous intraepithelial lesions (HSIL) compared with ASCUS. The cytologic interpretations in the ALTS were expert consensus diagnoses rather than routine, single-pathologist readings. METHODS The authors conducted a comparative analysis of Hybrid Capture 2 high-risk HPV positivity and frequency of histologically diagnosed HSIL for ASC-H and ASCUS to evaluate the performance of ASC-H as a cytologic interpretation subcategory and the potential utility of HPV testing for colposcopy triage of ASC-H in routine practice. RESULTS Sixty-four of 96 patients with ASC-H (66.7%) were HPV-positive compared with 484 of 1079 patients with ASCUS (44.9%). Among the patients who had histologic follow-up, HSIL was identified in 18 of 45 patients (40.0%) with HPV-positive ASC-H compared with 27 of 266 patients (10.2%) with HPV-positive ASCUS (P < 0.0001) and 1 of 22 patients (4.5%) with HPV-negative ASC-H (P = 0.003); the latter result was similar to the finding of HSIL in 5 of 85 patients (5.9%) with HPV-negative ASCUS. The frequency of HPV-positive ASC-H in the current study (67%) was lower than that obtained in the ALTS for ASC-H (86%) but higher than that for ASCUS in both this study (45%) and in the ALTS (51% for all ASC; 63% for ASCUS, equivocal for LSIL). Underlying HSIL was detected in a similar percentage of patients with HPV-positive ASC-H in this study and in the ALTS (41%). CONCLUSIONS The greater frequency of HPV positivity and the significantly increased risk of underlying HSIL for ASC-H compared with ASCUS indicated that ASC-H category utilization and performance are appropriate in this routine clinical practice setting. The lower frequency of HPV positivity for ASC-H compared with the ALTS data and the similar low risk of HSIL in HPV-negative ASC-H and HPV-negative ASCUS indicate that HPV testing for triage of ASC-H in routine practice has the potential to reduce the number of women who are referred for colposcopy without an increased risk of failure to detect HSIL among HPV-negative women, similar to its triage role for ASCUS.
