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 forCandidasp., 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 Objective.—To determine whether human papillomavirus (HPV) testing is useful in the evaluation of patients diagnosed with atypical squamous cells of undetermined significance (ASCUS)/low-grade squamous intraepithelial lesion (LSIL) and whether the HPV test is appropriate as an alternative screening method. Design.—The results of Papanicolaou (Pap) tests and subsequent hybrid capture tube (HCT) II tests for high-risk–type HPV were analyzed for 457 patients. Among these tests, 208 histologic diagnoses were made and correlated with the results of Pap and HPV tests. The sensitivity and specificity of the Pap test, HPV test, and the combined method of Pap and HPV tests to detect cervical intraepithelial neoplasia (CIN) 2/3 and all CIN were also measured. Results.—Sixty (63.8%) of 94 women with LSIL and 31 (26.3%) of 118 women with ASCUS tested positive for high-risk HPV. The sensitivity values for Pap tests in detecting all cases of CIN and CIN 2/3 were 91.4% and 92.9%, respectively. The sensitivity values of HCT II tests using the high-risk probe for detecting all cases of CIN and CIN 2/3 were 62.6% and 88.1%, respectively. Biopsies confirmed that 10 (22.7%) of 44 LSIL patients with high-risk HPV had CIN 2/3, but only 1 (4.5%) of 22 LSIL patients without high-risk HPV had CIN 2/3. Conclusion.—Testing for high-risk HPV with the HCT II test is useful in the detection of CIN 2/3 in LSIL groups and in the selection of patients for colposcopy in ASCUS groups, but it is not suitable for cervical cancer screening tests.

The aim of this study was to establish whether a combination of high-risk human papillomavirus (hrHPV) testing and cervical cytology could reduce colposcopy referral among women with atypical squamous cells of undetermined significance (ASCUS) or low-grade squamous intraepithelial lesion cytology. We randomized 598 women in the Helsinki area, Finland into three study groups. Different strategies of hrHPV testing, cytology and colposcopy with biopsy were used; subsequent hrHPV test results and cytological findings were compared with histology. The rates of hrHPV positivity and CIN2+ were compared. In total, 62.5% of all samples were hrHPV-positive. Altogether 45 (12.7%) CIN2 or worse (CIN2+) lesions were found in study groups A and B. Among hrHPV-positive women the rate of CIN2+ was 19.0% ( n = 43), in contrast with 1.6% ( n = 2) among hrHPV-negative women (relative risk = 12.2, 95% confidence interval [CI] 3.6–81.1, P < 0.001). Among all hrHPV-negative women whose cytological findings were normal or ASCUS, dysplastic lesions were uncommon ( n = 4/119, 3.4%), and all were CIN1. If these women had not been referred to colposcopy, the number of colposcopies would have been reduced by 33.6%. We conclude that hrHPV testing combined with repeat cervical cytology had a high negative predictive value in patients with recurrent low-grade cervical cytology. This could reduce the referral rate to colposcopy without jeopardizing patient safety.

Abstract Context.—Oncogenic, high-risk human papillomavirus (HR-HPV) testing is used to evaluate women who are older than 20 years with atypical squamous cells of undetermined significance (ASC-US) and in conjunction with a screening Papanicolaou test in women older than 30 years. Objectives.—To evaluate the 2006 laboratory practice data from laboratories incorporating human papillomavirus (HPV) testing with the Papanicolaou test. Design.—To use the College of American Pathologists (CAP) Supplemental Questionnaire Survey for 2006 to determine laboratory practices of participants in the CAP Interlaboratory Comparison Program in Cervicovaginal Cytology. Results.—A total of 679 laboratories responded to the questionnaire. Most (73%) refer HPV testing to reference laboratories. Nine percent perform HPV testing in cytology. Forty-five percent offer low-risk HPV (LR-HPV) testing. The most common reflex is ASC-US, although HR-HPV is also offered with low-grade squamous intraepithelial lesion (LSIL), high-grade squamous intraepithelial lesion (HSIL), or any other Papanicolaou test result. Digene Hybrid Capture II is the most common method. Human papilloma virus median test volumes are 55 monthly. Frequency distributions of HPV test volumes are significantly different from those found in 2003. Laboratories performing in-house testing reported significantly higher monthly HPV volumes (P &lt; .001). Median rates for HR-HPV positivity are 36.6% for ASC-US, 50.0% for atypical squamous cells, cannot exclude HSIL (ASC-H), and 4% for women 30 years of age and older in conjunction with a screening Papanicolaou test. Conclusions.—Reference HPV testing remains the most common pattern. The most common reflex indication is for ASC-US, but HPV testing is modified locally to include a variety of scenarios. LR-HPV testing is commonly offered despite its lack of clinical significance. These data form a baseline for ongoing monitoring of HPV testing practice trends.

Aim:To evaluate the role of p16INK4a immunoexpression and human papillomavirus (HPV) DNA test for the detection of dyskaryotic cells in high-risk women.Materials and Methods:This work was a retrospective diagnostic study conducted in the University Hospital of Thessaloniki from January to December 2008. The subjects were women with current or previous HPV infection and current or previous cervical intraepithelial lesion (with or without treatment) or clinical warts. All liquid-based cytological samples were tested for P16INKa and HPV DNA test. The accuracy parameters used for the outcome included sensitivity, specificity, and positive predictive value.Results:A total of 226 women were included; the mean age was 29 years. Expression of p16INK4a was detected in the cytological samples of 13% of the negative cases, 44% of the cases of atypical squamous cells of undetermined significance, 46% of the cases of low-grade squamous intraepithelial lesion, and 78% of the cases of high-grade squamous intraepithelial lesion. A total of 91 women tested positive for high-risk HPV infection, and 54 of those had p16INK4a-positive staining reaction cells. The concordance between the 2 tests, HPV DNA and p16, was 59% regarding infection-positive cases. Diffuse strong parabasal p16INK4a immunostaining (nuclear score >2) was observed in 17 cases of the abnormal cytological findings (atypical squamous cells of undetermined significance, 2 cases; low-grade squamous intraepithelial lesion, 8 cases; high-grade squamous intraepithelial lesion, 7 cases). Colposcopy-directed biopsies were used as the criterion standard for the detection of cervical intraepithelial neoplasia in 91 women. The sensitivity of p16INK4a was 95% and the specificity was 92%, whereas the sensitivity of high-risk HPV was 100% and the specificity was 78%. The positive predictive value of p16INK4a was 71%, whereas that of HPV DNA was 44%.Conclusion:The findings suggest that p16INK4a immunostaining can improve the accuracy of cytological examination and HPV DNA test and may be particularly useful in the triage of low-grade lesions.

To examine the diagnostic utility for squamous intraepithelial lesion (SIL) by cytological in situ hybridization (c-ISH) for the human papillomavirus using liquid-based cytology specimens, we investigated c-ISH signal patterns in the cases of low-grade SIL (LSIL), atypical squamous cells of undetermined significance (ASC-US), and high-grade SIL (HSIL). Episomal (E) and/or integrated (I) signals were observed. Two signal patterns (E≧I or I>E) were obtained by counting the number of E+ or I+ cells. E≧I was specific to LSIL and ASC-US (10/12); I>E, to HSIL (9/11) (P<0.01, χ2 test), suggesting significant utility of c-ISH in diagnosing SIL. In the cell fraction, E≧I in large cells was dominant in LSIL. Two cases of I>E in large cells of LSIL showed HPV persistence and/or progression during follow-up. Thus, c-ISH is useful in routine testing for diagnosing cervical dysplastic lesions, especially for detecting LSIL suspected for progression.

Introdução: A Gardnerella vaginalis facilita a infecção pelo papilomavírus humano (HPV). Objetivo: Verificar a associação entre anormalidades citológicas e presença de Gardnerella vaginalis nos esfregaços cervicovaginais encaminhados ao Laboratório Clínico da Pontifícia Universidade Católica de Goiás (LAC/PUC Goiás) estratificadas por faixa etária. Método: Estudo transversal realizado no LAC/ PUC Goiás entre janeiro de 2013 a dezembro de 2015. Para análises estatísticas, a variável idade foi categorizada em ≤39 anos e >40 anos, utilizando o programa IBM SPSS Statistics (Version 2.0, 2011®) para o teste de qui-quadrado (X²), com intervalo de confiança de 95% e valor p<0,05. Resultados: Foram analisados 4.558 exames citopatológicos, a maioria com presença de Lactobacillus spp. (46,97%). A prevalência dos agentes patogênicos foi a Gardnerella vaginalis (79,6%), seguida de Candida spp. (16,8%), Trichomonas vaginalis (2,2%), Herpes simplex (0,4 %) e Chlamydia trachomatis (0,1%). As anormalidades citológicas foram observadas em 9,1%, sendo atypical squamous cells of undetermined significance (ASC-US) 2,57%, low grade squamous intraepithelial lesion (LSIL) 1,78%, atypical squamous cells of undetermined significance cannot exclude high grade squamous intraepithelial lesion (ASC-H) 3,52%, high grade squamous intraepithelial lesion (HSIL) 1,08%, atypical endocervical cells, favor neoplastic (AGC-NEO) 0,22% e carcinoma 0,02%. Houve uma associação significante entre anormalidades citológicas graves e mulheres ≥40 anos, OR 3,01 (IC 95% 2,0-4,58) (p<0,0001). Mulheres ≤40 anos mostraram significância à presença de Gardnerella vaginalis (p<0,0004). Conclusão: Uma elevada prevalência de Gardnerella vaginalis foi encontrada associada com as anormalidades citológicas, principalmente em mulheres sexualmente ativas.
