A força das associações entre as variáveis foi aferida pelo risco relativo (RR) e intervalos de confiança (IC 95%). Resultados: As principais alterações presentes nos exames foram: alterações por células escamosas atípicas de significado indeterminado e lesão intraepitelial de baixo grau. Após análises estatísticas, notou-se que algumas alterações possuem risco maior de se desenvolverem no público fora da faixa etária preconizada, ou seja, entre mulheres com idade <25 anos ou >64 anos. Conclusão: O estudo realizado contribui para identificação do perfil atual vivenciado na área da saúde da mulher e possibilita a criação de condutas e ações que visem intervir frente aos resultados obtidos, impactando positivamente na realidade de Minas Gerais

Introduction: Early diagnosis and referral to a specialized service are essential to improve the cure and survival rates of women affected by cervical cancer. Thus, carrying out this study will make it possible to collect information that will be essential for the development of preventive measures, which aim to contribute to the development of health education actions and early diagnosis to reduce the morbidity and mortality of this disease. Objective: Identify the profile of the results of cervical cytopathological examinations of women residing in the State of Minas Gerais from the data of examinations corresponding to the year 2019, using the variables made available by the Cancer Information System.Methods: This is a retrospective, exploratory, quantitative study carried out by means of a secondary database. The data were submitted to analysis using the SPSS software, version 20.0. Descriptive statistics (absolute frequency, percentage, mean and standard deviation) were performed. To verify the association between qualitative variables, the chi-square test (x²) and Fisher's exact test were used. The strength of the associations between the variables was measured by the relative risk (RR) and confidence intervals (95% CI). Results: The main alterations present in the cytopathological exams performed were: changes due to atypical squamous cells of undetermined significance and low- grade intraepithelial lesion. After statistical analysis, it was noted that some changes have a higher risk of developing in the public outside the recommended age range, that is, among women aged <25 years or> 64 years. Conclusion: The study carried out contributes to the identification of the current profile experienced in the area of women's health and enables the creation of conducts and actions that aim to intervene in view of the results obtained, positively impacting the reality of Minas Gerais.

Alterações em exames citopatológicos realizados em Unidade Básica de Saúde: um estudo analítico transversal / Alterations in cytopathological tests performed in a Basic Health Unit: a cross-cutting analytical study

Objetivo: Com o presente estudo, buscou-se verificar a quantidade de exames de colpocitologia oncótica coletados em Unidade Básica de Saúde (UBS) escolhida, determinar quantas e quais são as alterações encontradas nesses exames e quais foram as condutas e acompanhamentos realizados em pacientes com exames alterados. Métodos: Foram analisados 446 exames de colpocitologia oncótica realizados em uma UBS do centro-oeste do Paraná. As pacientes com exame alterado foram selecionadas e foi feita uma análise desses prontuários a fim de verificar a conduta e o acompanhamento dessas pacientes. Resultados: Foram encontrados 32 exames com alterações, sendo três de uma mesma paciente. Dessas 30 pacientes, a grande maioria correspondia a células escamosas atípicas de significado indeterminado (ASC-US), possivelmente não neoplásicas, e 28 pacientes retornaram para receber uma conduta inicial, sendo principalmente o encaminhamento para a coleta de novo preventivo em seis meses ao serviço de oncologia clínica. Conclusão: O presente estudo concluiu que a hipótese principal foi verdadeira, a qual foi descrita como prevalência significativa de lesões intraepiteliais de alto grau, embora não seja a mais frequente, e descontinuidade por parte das pacientes que obtiveram esse resultado. Além disso, notou-se grande encaminhamento à atenção terciária, o que não é indicado pelo Ministério da Saúde.(AU)

Objective: With the present study, we sought to verify the amount of cytopathological tests collected in the chosen basic health unit, to determine how many and what are the alterations found in these tests and what were the conducts and follow-ups performed in patients with altered exams. Methods: We analyzed 446 preventive tests performed in a basic health unit in the Midwest of Paraná, and patients with altered examination were selected and an analysis of these medical records was made in order to verify the conduct and follow-up of the patients. Results: Thirty-two tests with alterations were performed, 3 of which were the same patient. Of these 30 patients, the vast majority corresponded to atypical cells of squamous meaning ­ possibly non-neoplastic (ASC-US), and 28 patients returned to receive an initial approach, mainly being referred to the collection of preventive new in 6 months and to the clinical oncology service. Conclusion: The present study concluded that the main hypothesis was true, which was described as a significant prevalence of high-grade intraepithelial lesions (HSIL), although not the most frequent, and discontinuity on the part of the patients who obtained this result. In addition, there was a large referral to tertiary care, which is not indicated by the Ministry of Health.(AU)

Avaliar a estrogenização tópica vaginal no seguimento de citologia oncótica de significado indeterminado, tipo ASC-H, na pós-menopausa. Estudo, tipo caso-controle, que avaliou mulheres menopausadas com diagnóstico de ASC-H, divididas em dois grupos, com e sem uso de estrogênio tópico vaginal (GE e GNE). Foi calculada razão de chance a partir de tabelas de contingência construídas com variação robusta. Foram analisados 128 prontuários, sendo 27% de pacientes do GNE e 72% do GE. Houve aumento de diagnósticos ASC-H no GNE. No GE, aproximadamente 68 vezes menos colposcopias inadequadas e diminuição do número de colposcopias e Cirurgia de Alta Frequência (CAF), com evidência na redução em 21 e 12,5 vezes, respectivamente. Diminuição do número de colposcopias com melhor adequação ao exame, número de biópsias inalterado e diminuição do número de cirurgias de alta frequência, no grupo com uso de estrogênio tópico vaginal durante o seguimento.

Current paper evaluates topic vaginal estrogenization following oncotic cytology of undetermined significance, type ASC-H, in postmenopausal women. A case-control study evaluated menopausal women diagnosed with ASC-H, divided into two groups, with and without the use of topic vaginal estrogen (GE and GNE). Odds ratios were calculated from contingency tables built with robust variation. 128 medical records were analyzed, 27% of which were from the GNE and 72% from the GE. There was an increase in ASC-H diagnoses in GNE. In GE, approximately 68 times less inappropriate colposcopies and a decrease in the number of colposcopies and High Frequency Surgery (HFS), with a reduction of 21 and 12.5 times, respectively. Decrease in the number of colposcopies with better adaptation to the exam, unchanged number of biopsies and decrease in the number of high-frequency surgeries, in the group using topic vaginal estrogen during the follow-up.

Clinical significance of human papillomavirus 16/18 E6 protein detection in shunting and prognosis of patients with atypical squamous cells of undetermined significance and low-grade squamous intraepithelial lesions / 肿瘤研究与临床

Objective To evaluate the value of human papillomavirus (HPV) 16/18 E6 protein detection in shunting and prognosis in patients with atypical squamous cells of undetermined significance (ASCUS) and low-grade squamous intraepithelial lesions (LSIL). Methods A total of 98 patients with ASCUS or LSIL from the Affiliated Cancer Hospital of Shanxi Medical University between May 2014 and May 2015 were selected as the subjects. All of them received the thin-cytologic test (TCT), HPV DNA, HPV16/18 E6 protein tests and colposcopy examination. After 3-year follow-up of patients with cervical intraepithelial neoplasia (CIN) grade Ⅰor bellow lesions diagnosed by biopsy and 30 negative controls, the above tests were performed again. The efficacies of all the tests were analyzed. The value of CIN grade Ⅱ or above was predicted. Results The sensitivity, specificity, positive predictive value and negative predictive value in predicting CIN grade Ⅱor above lesions of HPV16/18 E6 protein , HPV DNA and HPV16/18 DNA was 30.8％, 95.3％, 50.0％, 90.0％, respectively; 84.6％, 37.6％, 17.2％, 94.1％, respectively and 61.5％, 67.1％, 22.2％, 91.9％, respectively in shunting study. The relative risk (RR) of CIN grade Ⅱor above lesions in patients with positive HPV16/18 E6 protein, persistent positive HPV16/18 DNA and positive HPV16/18 DNA was 13.429, 10.231 and 8.343, respectively in the follow-up study. Odds ratio (OR) of HPV16/18 E6 positive protein presenting persistent positive HPV16/18 DNA was 34.833 (95％ CI 5.020-241.711). Conclusions In patients with ASCUS and LSIL, the specificity and positive predictive value of HPV16/18 E6 protein in predicting CIN grade Ⅱ or above lesions are higher than those of HPV DNA and HPV16/18 DNA. Moreover, these patients with HPV16/18 E6 protein positive have a higher risk of developing CIN grade Ⅱ or above lesions and persistent positive HPV16/18 DNA.

Hallazgos en colposcopia. Experiencia en una unidad de referencia / Findings in colposcopy. Experience in a reference unit

Resumen OBJETIVO: Describir los desenlaces colposcópicos de pacientes con alteraciones citológicas atendidas en una institución colombiana. MATERIALES Y MÉTODOS: Estudio observacional, trasversal y retrospectivo al que se incluyeron pacientes a quienes se tomó una colposcopia, indicada por reporte anormal en la citología (2012-2106). La muestra se seleccionó a partir de un muestreo aleatorio, estratificado por grupos etarios. Se establecieron las frecuencias de las alteraciones colposcópicas y de los reportes histológicos. RESULTADOS: Se incluyeron 372 pacientes. La principal indicación de la colposcopia fue el reporte de atipia de células escamosas de significado indeterminado (70.6%), seguido por lesiones intraepiteliales de bajo grado (16.9%) y pólipos endocervicales (2.9%). La colposcopia fue negativa en 32% de los casos, positiva en 31% y con inflamación en 21%. El resto de los casos correspondió a atrofia o pólipos. De las colposcopias positivas, el principal reporte fue de cambios menores o grado 1; sobre todo en las pacientes de 15 a 24 años. De las pacientes con biopsia se reportó un caso de adenocarcinoma (3.1%) y otro de carcinoma in situ (3.1%) en el mismo grupo etario. CONCLUSIÓN: La colposcopia identificó lesiones de alto y bajo grado clínicamente no significativas. La colposcopia es una herramienta decisiva para el diagnóstico de lesiones premalignas del cuello uterino.

Abstract OBJECTIVE: This study describes the colposcopic results of patients with cytological alterations in a Colombian institution. MATERIALS AND METHODOS: Observational Cross-sectional study based on retrospective data. Patients who underwent colposcopy due to abnormal cytologies during 2012-2106 were included. A stratified random sampling was carried out by age groups. The frequencies of colposcopic alterations and histological results were established. RESULTS: 372 patients were selected. The main indication for colposcopy was the ASCUS report (70.6%), followed by LSIL (16.9%) and endocervical polyps (2.9%). Colposcopy was negative in 32% of the cases, positive in 31% and inflammation in 21%. The rest of cases corresponded to varied findings such as atrophy or polyps. Of the positive colposcopies the main report was minor changes or grade 1; especially in patients between 15-24 years. Of the patients with a biopsy, one case of adenocarcinoma (3.1%) and another of carcinoma in situ (3.1%) were reported in the same age group. CONCLUSIONS: The realization of colposcopy identified the high-grade lesions in this population, but also detected clinically insignificant low-grade lesions. Colposcopy is a key tool for the diagnosis of premalignant lesions of the cervix.

Management of atypical squamous cell cases: A prospective study of women seen at a private health service in northeastern Brazil / Conduta em casos de células escamosas atípicas: um estudo prospectivo de mulheres atendidas pelo serviço de saúde privado no nordeste do Brasil

Abstract Objective To assess the management chosen by gynecologists after atypical squamous cells (ASCs) cytology results, and to evaluate the outcomes of these cases in Brazilian women. Methods A prospective observational study evaluated the initial management offered by the gynecologist in the case of 2,458 ASCs cytology results collected between January of 2010 and July of 2016. The outcomes of the cytology, high-risk human papilloma virus (HR-HPV) test and histology were compared in two subgroups: atypical squamous cells of undetermined significance (ASC-US) and atypical squamous cells-cannot exclude high-grade squamous intraepithelial lesion (ASC-H). Results In many cases of ASC-US (36.97%) and ASC-H (40.50%), no clinical actions were taken. Cytology was the most frequent follow-up chosen, including for cases of ASC-H, which goes against the conduct recommended in the national guideline. In women over 30 years of age, the period of time elapsed between an ASC-US result and a new cytology was in 13.03 months, in disagreement with the national guideline recommendations (p< 0.0001). Negative for intraepithelial lesions or malignancy (NILM) cytologic (p = 0.0026) and histologic (p = 0.0017) results in the follow-up were associated with prior ASC-US, while negative results for ASC-H were cytologically (p< 0.0001) and histologically associated with high-grade squamous intraepithelial lesion (HSIL) (p< 0.0001). Two invasive cervical carcinomas (ICCs) were found in the follow-up for ASC-H, and there was a statistically significant association (p = 0.0341). A positive HR-HPV test was associated with ASC-H (p = 0.0075). Conclusion The data suggest that even for a population of Brazilian women assisted at private clinics, the national guidelines recommendations for ASCs results are not followed.

Resumo Objetivo Avaliar a conduta adotada por ginecologistas após resultados citológicos apresentando células escamosas atípicas (ASCs) e os desfechos destes casos em mulheres brasileiras. Métodos Um estudo observacional prospectivo avaliou o manejo clínico inicial do ginecologista nos casos de 2.458 resultados citológicos apresentando ASCs coletados entre janeiro de 2010 e julho de 2016. Os respectivos desfechos citológicos, histológicos e de detecção do papilomavírus humano (HPV) foram comparados entre os subgrupos células escamosas atípicas de significado indeterminado (ASC-US) e células escamosas atípicas não podendo excluir lesão intraepitelial de alto grau (ASC-H). Resultados Nenhuma conduta foi adotada em 36,97% de citologias do tipo ASC-US e 40,5% do tipo ASC-H. A conduta mais escolhida foi a repetição da citologia, inclusive para acompanhamento de ASC-H, o que contraria as diretrizes nacionais. O tempo de realização de uma nova citologia para resultado do tipo ASC-US em mulheres com mais de 30 anos de idade foi de 13,03 meses, também em desacordo com as diretrizes (p< 0,0001). Resultados negativos para lesão intraepitelial ou neoplasia maligna (NILM), tanto citológicos (p = 0,0026) como histológicos (p = 0,0017), foram associados a ASC-US, enquanto que resultados negativos para lesões intraepiteliais escamosas de alto grau (HSILs), citológicos (p< 0,0001) e histológicos, foram associados a ASC-H (p< 0,0001). Dois carcinomas cervicais invasivos foram encontrados durante o acompanhamento para ASC-H e uma associação estatisticamente significante foi estabelecida (p = 0,0341). Um teste de HR-HPV positivo foi associado a ASC-H (p = 0,0075). Conclusão Os dados sugerem que mesmo para uma população de mulheres brasileiras atendidas em clínicas privadas, as recomendações das diretrizes clínicas nacionais para resultados citológicos apresentando ASCs não são seguidas.

Risks of cervical intraepithelial neoplasia grade 3 or invasive cancers in ASCUS women with different management: a population-based cohort study / 부인종양

OBJECTIVE: To investigate the progression risk of atypical squamous cells of undetermined significance (ASCUS) with different clinical managements. METHODS: Women with their first diagnosis of ASCUS cytology were retrieved from the national cervical cancer screening database and linked to the national health insurance research database to identify the management of these women. The incidences of developing cervical intraepithelial neoplasia grade 3 and invasive cervical cancer (CIN3+) were calculated, and the hazard ratios (HRs) were estimated using a Cox proportional hazards model. This study was approved by the Research Ethics Committee of the National Taiwan University Hospital and is registered at ClinicalTrials.gov (Identifier: NCT02063152). RESULTS: There were total 69,741 women included. Various management strategies including colposcopy, cervical biopsies and/or endocervical curettage, and cryotherapy, failed to reduce the risk of subsequent CIN3+ compared with repeat cervical smears. Loop electrosurgical excision procedure/conization significantly decreased risk of subsequent CIN3+ lesions (HR=0.22; 95% confidence interval [CI]=0.07–0.68; p=0.010). Women in their 40s–50s had an approximately 30% risk reduction compared to other age groups. Women with a previous screening history >5 years from the present ASCUS diagnosis were at increased risk for CIN3+ (HR=1.24; 95% CI=1.03–1.49; p=0.020). CONCLUSION: In women of first-time ASCUS cytology, a program of repeat cytology can be an acceptable clinical option in low-resource settings. Caution should be taken especially in women with remote cervical screening history more than 5 years.

Comparison of the PANArray HPV Genotyping Chip Test with the Cobas 4800 HPV and Hybrid Capture 2 Tests for Detection of HPV in ASCUS Women

PURPOSE: This study aimed to evaluate the performance of the PANArray human papilloma virus (HPV) test, a PCR-based DNA microarray assay, in detecting HPV from patient samples and its concordance with the cobas 4800 HPV and Hybrid Capture 2 (HC2) tests. MATERIALS AND METHODS: The PANArray HPV, cobas 4800 HPV, and HC2 tests were performed on 504 cervical swab samples from patients with atypical cells of undetermined significance at five hospitals. The samples that were interpreted as ‘HPV-other’ type positive in the PANArray HPV test were confirmed by direct sequencing. RESULTS: The concordance rates were 80.8% between the cobas 4800 HPV and PANArray HPV tests [κ=0.59, 95% confidence interval (CI) 0.52–0.66] and 80.2% (κ=0.6, 95% CI 0.55–0.68) between the HC2 and PANArray HPV tests. Among the 62 patients negative on PANArray HPV (defined as the absence of high risk HPV), but positive on both cobas 4800 HPV and HC2 tests, 42 (67.7%) tested positive for ‘HPV-other’ types on the PANArray HPV test, and 31 (50.0%) had gray zone results [relative light unit/control (RLU/CO), 1.4–9.25] in the HC2 test. Of the patients deemed positive by the PANArray HPV test, 43 tested positive for high-risk (HR) HPV in cobas 4800 HPV and HC 2 tests. Among them, 58.2% showed HR HPV, including HPV 16, by direct sequencing, of which 25% had gray results. CONCLUSION: Results classified as ‘HPV-other’ type by the PANArray HPV test, or gray zone results by HC2 (RLU/CO ratio level 1–10) should be carefully interpreted using comprehensive clinical information.

Roles of HPV detection in 28 923 patients with atypical squamous cells of undetermined significance: analysis of 104 studies from China / 中华病理学杂志

Objective@#To investigate the human papillomavirus (HPV) positive rate and its usefulness in predicting CIN2+ in women with atypical squamous cells of undetermined significance (ASC-US) cervical cytology.@*Methods@#A pooled analysis was conducted using published data of hospital classification, HPV positive rate and histopathologic diagnosis in ASC-US population during 2005 to 2017 from 104 studies which enrolled 28 923 ASC-US samples.@*Results@#The overall HPV positive rate was 52.09% (range from 12.06% to 88.68%). The HPV positive rate in 79 tertiary hospitals of 21 244 cases was 52.46%, slightly higher than the 50.87% in 22 second-class hospitals of 6 925 cases. There was no significant difference between specialized hospitals and general hospitals. In addition, the positive rate of HC2 conducted in 66 hospitals with 19 791 cases was 53.13%, which was slightly higher than 51.10% of reverse hybridization from 24 hospitals with 6 338 cases. In 73 studies of 18 163 cases with histological diagnosis, the sensitivity of HPV for detecting CIN2+ was 90.16% (95%CI: 88.91% to 91.28%), specificity was 53.08% (95%CI: 53.02% to 54.57%), positive predictive value was 23.24% and negative predictive value was 97.24%.@*Conclusion@#HPV detection is clinically validated for ASC-US triage, but there is a wide variation of HPV positive rate in population of cervical cytological diagnosis as ASC-US in China, suggesting different diagnostic level between regions and hospitals and further improvement is needed.

The clinical performance of high risk HPV DNA test among triage women with cytology showing atypical squamous cells of undetermined significance / 中华预防医学杂志

Objective@#To evaluate the performance of high risk human papillomavirus (HR-HPV) DNA test for triage ASC-US in Chinese population.@*Methods@#The study population was from Jiyuan city in Henan Province where a cervical cancer screening cohort (4 026 women) was set up from April to July in 2017. Women with ASC-US and complete recall information of colposcope were selected as the study objects. Self-designed questionnaire was used to survey the general information and medical history of cervical cancer, thencervical cytological speciments were collected for cytodiagnosis and HPV DNA test, followed by colposcopy, lesion biopsy and histology diagnose. The diagnosis of histology was used as the gold standard. The sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) as well as corresponding 95% confidential interval (CI) were calculated.@*Results@#The average age of the included 393 women with ASC-US were (50.81±9.22) years old. The positivity of high risk human papillomavirus (HR-HPV), HPV16 and HPV18 were 35.6%, 10.69% and 2.80%, respectively. The sensitivity, specificity, PPV and NPV for HR-HPV to detect CIN2+ were 84.38% (68.25%-93.14%), 68.70% (63.74%-73.26%), 19.29% (13.61%-26.61%) and 98.02% (95.46%-99.15%). When compared with HR-HPV, HPV16/18 had a lower sensitivity (59.38% (42.26%-74.48%)) and a higher specificity(91.14% (87.75%-93.65%)), the PPV and NPV were 59.38% (25.32%-50.98%) and 91.14% (93.61%-97.77%).@*Conclusion@#It was more effective for HR-HPV to triage ASC-US than HPV16/18. In order to improve the effect of HPV16/18, it should include more HR-HPV types which were more prevalent in Chinese population.

Objective To investigate the application value of p16/cell proliferation associated nuclear antigen (Ki-67) double-staining and human papillomavirus mRNA in the cytological screening.Methods Two hundred and fifty-one cases who suffered from atypical squamous cell of undetermined significance (ASCUS),low-grade squamous intraepithelial lesion (LSIL),atypical squamous cell-cannot exclude high-grade squamous intraepithelial lesion (ASC-H) in ThinPrep cytologic test (TCT) were collected in Peking University First Hospital between October 2015 and March 2016.And p16/Ki-67 double-staining and hybrid capture Ⅱ (HC-Ⅱ) detection were performed on the cervical cells.The result was compared with the pathological result of colposcope guided biopsy.All statistical analysis was completed by Stata 12.0 statistical software analysis.The results of diagnostic tests were described by using the sensitivity,specificity,positive predictive value,negative predictive value,and the area under the receiver operating characteristic (ROC) curve.Results (1) One hundred and eight cases of liquid based cytology diagnosis of ASCUS patients,the positive rate of p16/Ki-67 was 13.9％ (15/108),102 cases of liquid based cytology diagnosis of LSIL patients,the positive rate of p16/Ki-67 was 21.6％ (22/102),41 cases of liquid based cytology diagnosis of ASC-H patients,the positive rate of p16/Ki-67 was 39.0％ (16/41),compared amongthree groups,the difference was statistically significant (x2=78.516,P＜0.05);cervical exfoliated cells p16/Ki-67 expression rate was 13.0％ (28/215) in cervical low-grade lesions [cervical intraepithelial neoplasia (CIN)Ⅰ],which was 69.4％ (25/36) in high level lesions (CIN Ⅱ-Ⅲ),the difference was statistically significant (x2=7.932,P＜0.05).(2) The specificity of p16/Ki-67 detection and diagnosis were higher than those of HC-Ⅱ in ASCUS,LSIL,and ASC-H (89.8％ vs 71.4％,83.3％ vs 15.6％,88.9％ vs 40.7％;all P＜0.05),meanwhile,the positive predictive value of p16/Ki-67 detection and diagnosis exceed those of HC-Ⅱ in ASCUS,LSIL,and ASC-H (33.3％ vs 26.3％,31.8％ vs 12.6％,81.3％ vs 38.5％;all P＜0.05).Moreover,the ROC curve of p16/Ki-67 were bigger than those of HC-Ⅱ in ASCUS,LSIL,and ASC-H (0.799 vs 0.696,0.708 vs 0.531,0.909 vs 0.561;all P＜0.05).Conclusion For patients with cytological diagnosis of ASCUS,LSIL,and ASC-H,p16/Ki-67 double staining method could be used as an effective method to assist in the diagnosis of high-grade cervical lesions,and the screening efficiency is superior to that of high-rist HPV.

Atypical squamous cells of undetermined significance and low-grade squamous intraepithelial lesion triage in Korean women: Revisiting the 2012 American Society of Colposcopy and Cervical Pathology screening guidelines

OBJECTIVE: To determine whether triage for atypical squamous cells of undetermined significance (ASC-US) and low-grade squamous intraepithelial lesion (LSIL) from the updated American Society for Colposcopy and Cervical Pathology cervical cancer screening guidelines is applicable in Korean women. METHODS: We investigated women with ASC-US or LSIL including referred from local hospitals visited for cervical cancer screening at Korea University Guro Hospital from February 2004 to December 2014. Detailed information on the results of Papanicolaou (Pap) smears, human papillomavirus (HPV) DNA tests, and cervical biopsies were collected through chart review. Cervical biopsy results were compared in eligible women according to individual Pap smear findings and HPV DNA status. RESULTS: Of 216,723 possible cases, 3,196 were included. There were 212 (6.6%) women with ASC-US and 500 (15.6%) with LSIL. The risk of ≥cervical intraepithelial neoplasia (CIN) 2 was significantly higher in women who were ASC-US/HPV+ than ASC-US/HPV- and LSIL/HPV+ than LSIL/HPV- (93.3% vs. 6.7% and 96.7% vs. 3.3%, P<0.001 and P<0.001, respectively). The risk of ≥CIN 3 was also significantly higher in women who were ASC-US/HPV+ than ASC-US/HPV- and LSIL/HPV+ than LSIL/HPV- (97.0% vs. 3.0% and 93.0% vs. 7.0%, P<0.001 and P<0.001, respectively). Age-stratified analysis revealed that more CIN 2 or CIN 3 was diagnosed in women aged 30 to 70 with ASC-US or LSIL when HPV DNA was present. CONCLUSION: Observation with Pap and HPV DNA tests rather than immediate colposcopy is a reasonable strategy for ASC-US or LSIL when the HPV DNA test is negative, especially in women aged 30 to 70. Reflection of these results should be considered in future Korean screening guidelines.

Impact of age on the false negative rate of human papillomavirus DNA test in patients with atypical squamous cells of undetermined significance

OBJECTIVE: Human papillomavirus (HPV) test was incorporated into the triage of lesser abnormal cervical cytologies: atypical squamous cells of undetermined significance (ASCUS) or low-grade squamous intraepithelial lesion (LSIL). This study aimed to evaluate the impact of age on the efficacy of HPV testing in patients with lesser abnormal cervical cytologies. METHODS: A total of 439 patients with ASCUS or LSIL were included. The association between age groups and the diagnostic performances of HPV test for high-grade cervical intraepithelial neoplasia (CIN2+) was evaluated. RESULTS: Median age was 44 years (range, 17 to 75 years). ASCUS was more frequently observed in older patients while LSIL was more common in younger patients (P=0.002). CIN2+ was found in 11.3% (32/284) of the ASCUS patients and 12.9% (20/155) of patients with LSIL. Older patients with ASCUS showed lower HPV infection rates (P=0.025), but not LSIL (P=0.114). However, the prevalence of CIN2+ was similar between the age groups with ASCUS or LSIL. In patients with ASCUS, the false negative rate of HPV test for CIN2+ was 6.2%. The false negative rate of the HPV test became higher with increasing of the age after the age of 50 (P=0.034). CONCLUSION: Our findings suggest that false negative rate of the HPV test for CIN2+ in ASCUS patients older than 50 years might become higher with increasing of the age. Negative HPV results in patients of the age >50 years with ASCUS should be carefully interpreted.

Exploring in management of women with atypical squamous cells of undetermined significance / 实用医学杂志

Objective Exploring in processing method to triage of women with a cytologic smear showing atypical squamous cells of undetermined significance. Methods All 130 cases were diagnosed with ASCUS received high-risk HPV (hr-HPV)test, colposcopic inspections, reformeded Reid's colposcopic index score and cervical biopsies for pathological examination. Resluts The pathology of 130 ASCUS patients included 31cases of normal and inflammation (23.90%), 29 cases of CINⅠ(22.30%), 14 cases of CINⅡ(10.80%), 55 cases of CINⅢ or cervical carcinoma in situ (42.30%), and 1 case of invasive cervical carcinoma (0.80%). The reformed Reid's colposcopic index score of 130 ASCUS patients included 32 cases of 0 score (24.60%), 36 cases of 1~2 scores (27.70%), 47 cases of 3~4 scores(36.10%), 15 cases of 5~6 scores(11.60%). 2. The colposcopy used to detect the CIN of ASCUS, its sensitivity was 98.99%(98/99), specificity was 51.61%(16/31). The hr-HPV used to detect the CIN of ASCUS, its sensitivity was 96.97%(96/99), specificity was 32.26%(10/31). Conclusion Both the reformeded Reid′s colposcopic index score and hr-HPV testing as the clinical triage methods of ASCUS. The former has good sensitivity and specificity ,which is superior to hr-HPV testing.

The importance of immediate verification of a cervical cytological abnormality with histology.

Background: A serious proportion of the patients with invasive cervical cancer can be women who have had abnormal smear findings known for at least 6 months. Aims: The aims of the study were to evaluate the cervical cytohistopathologic correlation in the population studied, and to discuss the acceptability of immediate histological verification for minor Papanicolaou smear abnormalities. Materials and Methods: A total of 443 patients who were admitted with abnormal smear results and had undergone immediate colposcopy, cervical biopsy and endocervical curretage in the gynecologic oncology clinic between the years of 2003-2009 were enrolled into the present retrospective study. One-way analysis of variance and independent t-tests were used to study the results. Results: The distribution of abnormal smear results were documented as 46.27%, 29.57%, 13.76%, 7.67%, 1.58%, 0.67%, and 0.45% for atypical squamous cells of undetermined significance (ASC-US), low-grade squamous intraepithelial lesion (LSIL), high-grade squamous intraepithelial lesion (HSIL), atypical squamous cells cannot exclude high-grade squamous intraepithelial lesion (ASC-H), squamous cell carcinoma (SCC), atypical glandular cell (AGC), and adenocarcinoma, respectively. The percentages of cervical intraepithelial neoplasia grade 2-3 (CIN 2-3) and greater lesions were 70.49%, 35.29%, 15.26%, and 9.75% for HSIL, ASC-H, LSIL, and ASC-US, respectively. Moreover, 38.36% of all the CIN 2-3 or cancer (n = 104) cases originated from those with low grade referral diagnosis (ASC-US and LSIL). Conclusions: The majority of cases in the study were predominantly ASC-US and LSIL and approximately 40% of all the high grade lesions came from those with low grade referral diagnosis. This shows poor cytohistopathological correlation and calls the triage of minor cytological abnormalities into question.
