Transumbilical Single-port Total Laparoscopic Hysterectomy by Conventional Instruments Without Uterine-lifting / 中国微创外科杂志

Objective To investigate the application value of transumbilical single-port total laparoscopic hysterectomy by conventional instrument without uterine-lifting in the treatment of cervical lesions.Methods We selected 60 cases of total laparoscopic hysterectomy due to cervical high-grade squamous intraepithelial lesion(HSIL)or cervical cancer stage ⅠA1 from December 2021 to June 2023.According to the patients'preference,30 cases of single-port laparoscopy through the umbilicus and 30 cases of multi-port laparoscopy were performed,both using conventional instruments without uterine-lifting.The surgical indicators of the two groups were compared.Results No conversion to open surgery occurred in both groups,and no intraoperative injuries to the urinary system,bowel,or major blood vessels occurred.As compared with the multi-port group,the single-port group had significantly reduced amount of bleeding during surgery[(54.6±20.5)ml vs.(67.5±27.0)ml,P = 0.041],earlier anal exhaust time[(27.6±8.0)h vs.(32.2±9.0)h,P =0.040],and shorter total hospitalization time[(4.4±1.5)d vs.(5.1±1.2)d,P = 0.044].There were no significant differences in uterine weight,surgical time,and postoperative complications between the two group(P>0.05).The healing of the abdominal wall puncture wounds in both groups of patients were satisfied.There were no short-term complications related to the puncture device(such as puncture wound infection and bleeding)or long-term complications(such as umbilical hernia and incisional hernia).Conclusion Transumbilical single-port total laparoscopic hysterectomy without uterine-lifting presents advantages of less intraoperative bleeding,faster postoperative recovery,and almost no scarring,with complications similar to traditional laparoscopic surgery.

Differential expression of FAM83A and β-catenin in cervical lesions / 安徽医科大学学报

Objective @# To investigate the expression difference and potential clinical significance of 83 sequence similar member A (FAM83A) and β-catenin in cervical lesions．@*Methods @#ALCAN and GEPIA2. 0 online data- bases were used to analyze the difference of FAM83A expression in normal cervix and cervical squamous cell carci- noma ( CSCC) and the relationship between FAM83A expression and the prognosis of CSCC patients，LinkedOmics database was used to analyze FAM83A mRNA co-expression genes，and R language was used for KEGG enrichment analysis．Immunohistochemistry was used to detect FAM83A and β-catenin expression in 60 cases of normal cervix， 80 cases of low-grade squamous intraepithelial lesion ( LSIL) ，90 cases of high-grade squamous intraepithelial le- sion (HSIL) and 70 cases of cervical squamous cell carcinoma ( CSCC) ．The relationship between FAM83A ，β - catenin expression and clinicopathological features and the correlation between FAM83A and β-catenin expression were analyzed. @*Results @# UALCAN database analysis showed that FAM83A was highly expressed in CSCC tissues， and GEPIA 2. 0 database analysis suggested that those with high FAM83A expression had a poor prognosis．Linke- dOmics database performing KEGG enrichment analysis suggested that expression of FAM83A was positively correla- ted with aberrant activation of Wnt / β-catenin signaling pathway． The expression rate of FAM83A in CSCC was higher than that in LSIL and normal cervical tissues (P＜0. 001) ，but there was no significant difference compared with HSIL (P = 0. 401) ; the expression of FAM83A was not correlated with age (P = 0. 231) ，but was significant- ly different from the correlation with differentiation (P = 0. 001) and clinical stage (P = 0. 038) ．The abnormal ex- pression rate of β-catenin in CSCC was higher than that in LSIL and normal cervical tissues (P＜0. 001) ，but there was no significant difference compared with HSIL (P = 0. 734) ; the expression of β-catenin was not related to age (P = 0. 088) ，related to differentiation (P = 0. 001) and clinical stage (P＜0. 001) ，and FAM83A was positively correlated with β-catenin expression (P ＜0. 05 ) ．@*Conclusion @#FAM83A and β-catenin are highly expressed in both HSIL and CSCC tissues，and there is a positive correlation between the expression of FAM83A and β-catenin. The high expression of FAM83A has some correlation with the prognosis of CSCC patients and can be used as a po- tential marker to determine the prognosis of CSCC.

P16/Ki-67 double dye the value of diagnosis of cervical intraepithelial lesions and cervical biopsy consistency analysis / 国际检验医学杂志

Objective To evaluate the role of P16/Ki-67 double dye in the diagnosis of cervical intraepithe-lial lesion(CIN)value,and to analyze its consistency with cervical biopsy.Methods A total of 92 patients with suspected CIN in Shanghai Songjiang District Central Hospital from November 2021 to April 2023 were selected as the research objects.All patients underwent high-risk human papillomavirus(HR-HPV)and P16/Ki-67 double dye.Taking cervical biopsy as the gold standard,the diagnostic value of the two detection meth-ods for CIN was analyzed,as well as the consistency of the two detection methods in the diagnosis of CIN clas-sification and cervical biopsy.Results The results of cervical biopsy showed that 74 cases(80.43%)of 92 suspected CIN patients were positive,including 26 cases of CIN Ⅰ,32 cases of CIN Ⅱ and 16 cases of CIN Ⅲ,and 18 cases(19.57%)were negative.Taking cervical biopsy results as the gold standard,P16/Ki-67 double dye was more accurate than HR-HPV test in the diagnosis of CIN(P<0.05).The receiver operating charac-teristic(ROC)curve showed that the area under the curve of HR-HPV and P16/Ki-67 double dye for CIN di-agnosis was 0.760 and 0.890,respectively,all of them had certain diagnostic value.The consistency between HR-HPV evaluation of CIN classification and cervical biopsy was consistent(Kappa=0.707,P<0.05).The consistency between P16/Ki-67 double dye and cervical biopsy was excellent(Kappa=0.832,P<0.05).Con-clusion P16/Ki-67 double dye with a high diagnostic value in CIN,consistency in determining CIN grade and cervical biopsy is wonderful,which can provide reference for clinical diagnosis.

Analysis of influencing factors for underdiagnosis of high-grade squamous intraepithelial lesion of the uterine cervix and cervical cancer by colposcopy / 肿瘤研究与临床

Objective:To investigate the influencing factors for underdiagnosis of high-grade squamous intraepithelial lesion (HSIL) of the uterine cervix and cervical cancer by colposcopy.Methods:The clinical data of 957 patients who underwent colposcopy and were diagnosed as HSIL or cervical cancer by histopathology at the Second Hospital of Shanxi Medical University from January 2017 to June 2022 were retrospectively analyzed, and logistic regression was used to analyze the influencing factors for underdiagnosis of HSIL and cervical cancer by colposcopy.Results:The results of univariate analysis showed that the underdiagnosis of HSIL and cervical cancer by colposcopy was related to whether or not menopause was present, whether or not there was coitus bleeding, whether or not there was irregular bleeding, liquid-based thin-layer cytology test (TCT) results, the morphology of the uterine cervix, the results of acetowhitening test, the results of iodine test, whether or not there was cuffed crypt (gland) openings, whether or not there was mosaicism, whether or not there was punctate vessels, whether or not the transformed zone was completely visible, the type of transformed zone, and whether or not the lesions involved the glands (all P < 0.05), but the underdiagnosis didn't related to whether or not there was human papillomavirus (HPV) infection, whether or not there was high-risk HPV multiple infections and the results of endocervical curettage (all P > 0.05). The results of multivariate logistic regression analysis showed that irregular bleeding ( OR = 4.279, 95% CI 2.170-8.441, P < 0.001), atypical squamous cells of uncertain significance (ASC-US) by TCT ( OR = 0.415, 95% CI 0.226-0.761, P = 0.004), atypical squamous cells, cannot exclud high-grade squamous intraepithelial lesion (ASC-H)/HSIL by TCT ( OR = 0.389, 95% CI 0.206-0.735, P = 0.004), thick acetowhite epithelium by acetowhitening test ( OR = 0.015, 95% CI 0.004-0.055, P < 0.001), and punctate vessels ( OR = 0.327, 95% CI 0.173-0.616, P = 0.001) were independent influencing factors for underdiagnosis of HSIL and cervical cancer by colposcopy. Conclusions:A history of irregular bleeding is a risk factor for underdiagnosis of HSIL of the uterine cervix and cervical cancer by colposcopy, while TCT results of ASC-US, ASC-H/HSIL and colposcopic visualization of thick acetowhite epithelium and punctate vessels could reduce the risk of underdiagnosis

Abstract OBJECTIVE: To determine the concordance in cytologic, colposcopic and histopathologic findings in premalignant lesions of the uterine cervix. MATERIALS AND METHODS: Cross-sectional, retrospective and comparative study, carried out in the dysplasia clinic of the Hospital General Regional 1 of the state of Querétaro, Mexico, from January 1 to December 2020, based on information from the records of women with cytology, colposcopy and histopathology (biopsy) report with low- and high-grade intraepithelial lesion. The statistical analysis plan included confidence intervals for averages and percentages. The weighted Kappa Index was used to determine the level of concordance. RESULTS: Two hundred and ninety records were analyzed. The mean age of the patients was 36 years, the weighted kappa index was k = 0.41 (95%CI: 0.33-0.53) for cytology and colposcopy with a moderate value (fair). For cytology and biopsy, it was k= 0.33 (95%CI: 0.22-0.49) with a poor value (medium). For colposcopy and biopsy, it was k = 0.61 (95%CI: 0.49-0.72) with a value of good (substantial) agreement. CONCLUSION: Between cytology and colposcopy the concordance coefficient was moderate, for cytology and biopsy it was poor, while for colposcopy and biopsy it was a substantial.

Asociación entre el inicio de la vida sexual y las lesiones intraepiteliales / Association between age at onset of active sexual life and intraepithelial lesion

Introducción: El cáncer cervicouterino inicia con una lesión precancerosa llamada displasia, pudiendo ser de bajo grado o alto grado; uno de los factores más importantes en este sentido es la edad de inicio de la vida sexual activa (IVSA). Objetivo: Conocer si existe asociación entre la edad de inicio de la vida sexual activa y la lesión intraepitelial escamosa de alto grado (LIEAG). Material y métodos: Estudio descriptivo, retrospectivo, observacional, en 52 expedientes de mujeres de 15 a 60 años, con Papanicolaou en el HGZ MF No. 1, previa autorización del CLIS 301 y el CEI 3018, con folio R-2022-301-021. Se recolectaron los datos de expedientes que cumplieron los criterios de inclusión; se realizó un análisis estadístico con frecuencias, porcentajes para variables cualitativas nominales, con medidas de tendencia central y dispersión en variables cuantitativas, con determinación de chi2 y prueba de Kruskal-Wallis, respetándose los principios de Belmont en consideración a la Justicia y Beneficencia, los principios éticos de la Declaración de Helsinki 1964 y la Ley General de Salud en México. Resultado: Al evaluar 52 expedientes de pacientes, la edad fue de 37.81 ± 9.949 años; se encontró asociación entre el IVSA y la LIEAG, sin significación estadística, de acuerdo con la prueba de chi2, con un valor de p = 0.538 (IC 95%: 0.403-0.674), y una asociación significativa por la prueba de Kruskal-Wallis entre la LIEAG y la edad de la paciente, con un valor de p = 0.019 (IC 95%: 0.000-0.057). Conclusión: El IVSA no se correlaciona con el tipo de LIEAG.

Introduction: Cervical cancer begins with a precancerous lesion called dysplasia, which can be low grade or high grade. One of the most important factors is the age at which an active sexual life begins. Objective: To know if there is an association between the age of beginning of active sexual life (BASL) and high-grade squamous intraepithelial lesions (HGSIEL). Material and methods: Descriptive, retrospective, observational study, in 52 files of women aged 15 to 60 years with Pap smear at HGZ MF No. 1, prior authorization from CLIS 301 and CEI 3018 with folio R-2022-301-021. Data were collected from files that met the inclusion criteria, a statistical analysis was carried out with frequencies, percentages for nominal qualitative variables, with measures of central tendency and dispersion in quantitative variables, with determination of chi2 and Kruskal-Wallis, respecting the principles of Belmont in consideration of Justice and Beneficence, the ethical principles of the Declaration of Helsinki 1964, the General Health Law in México. Result: When evaluating 52 patient records, the age was 37.81 ± 9.949 years, the association of BASL and HGSIEL was found without statistical significance according to the chi2 with a p = 0.538 (95% CI, 0.403-0.674) and a significant association by Kruskal-Wallis between HGSIEL and patient age, with p = 0.019 (95% CI, 0.000-0.057). Conclusion: The beginning of an active sexual life has no association with the type of high-grade squamous intraepithelial lesions.

Cytology-based Screening for Anal Intraepithelial Neoplasia in Immunocompetent Brazilian Women with a History of High-Grade Cervical Intraepithelial Neoplasia or Cancer / Triagem citológica de neoplasia intraepitelial anal em mulheres brasileiras imunocompetentes com histórico de neoplasia intraepitelial cervical de alto grau ou câncer

Abstract Objective To determine the prevalence and possible variables associated with anal intraepithelial neoplasia and anal cancer in immunocompetent women with high-grade cervical intraepithelial neoplasia. Methods A cross-sectional study involving immunocompetent women with a histological diagnosis of high-grade cervical intraepithelial neoplasia and cervical cancer, conducted between January 2016 and September 2020. All women underwent anal cytology and answered a questionnaire on characterization and potential risk factors. Women with altered cytology were submitted to anoscopy and biopsy. Results A total of 69 women were included in the study. Of these, 7 (10.1%) had abnormal anal cytology results: (high-grade lesion, atypical squamous cells of undetermined significance, and atypical squamous cells, cannot exclude high-grade lesions: 28,5% each; low grade lesion: 14,3%). Of the anoscopies, 3 (42.8%) showed alterations. Of the 2 (28,5% of all abnormal cytology results) biopsies performed, only 1 showed low-grade anal intraepithelial neoplasia. The average number of pregnancies, vaginal deliveries, and abortions was associated with abnormal anal cytology. However, the highest mean regarding the cesarean sections was associated with normal cytology. Conclusion The prevalence of anal intraepithelial neoplasia was compatible with data from recent studies, especially those conducted in Brazil. Opportunistic screening for anal intraepithelial neoplasia in this high-risk population should be considered. Anal cytology is suitable for this purpose, due to its low cost and feasibility in public health services.

Resumo Objetivo Determinar a prevalência e as possíveis variáveis associadas à neoplasia intraepitelial anal e ao câncer anal em mulheres imunocompetentes com neoplasia intraepitelial cervical de alto grau. Métodos Estudo transversal em mulheres imunocompetentes com diagnóstico histológico de neoplasia intraepitelial cervical de alto grau e câncer cervical, feito entre janeiro de 2016 e setembro de 2020. Todas as mulheres foram submetidas a citologia anal e responderam a um questionário de caracterização e potenciais fatores de risco. Mulheres com citologia alterada foram submetidas a anuscopia e biópsia. Resultados No total, 69 mulheres foram incluídas no estudo. Destas, 7 (10,1%) tiveram resultados anormais de citologia anal (lesão de alto grau, células escamosas atípicas de significado indeterminado, e células escamosas atípicas, não se pode excluir lesões de alto grau: 28,5% cada; lesão de baixo grau: 14,3%). Das anuscopias, 3 (42,8%) demonstraram alterações. Das 2 biópsias realizadas, apenas 1 apresentou neoplasia intraepitelial anal de baixo grau. O número médio de gestações, partos vaginais e abortos estava associado à citologia anal anormal. No entanto, a maior média de partos cesáreos estava associada à citologia normal. Conclusão A prevalência de neoplasia intraepitelial anal foi compatível com dados de estudos recentes, principalmente daqueles feitos no Brasil. O rastreamento oportunista para neoplasia intraepitelial anal nesta população de alto risco deve ser considerado. A citologia anal é adequada para esse fim, devido ao seu baixo custo e viabilidade nos serviços públicos de saúde.

Virus de papiloma humano y lesión intraepitelial cervical enadolescentes embarazadas / Human papilloma virus and cervical intraepithelial lesion inpregnant adolescents

Objetivo: Comparar la presencia del Virus de Papiloma Humano (VPH) y de lesión Intraepitelial Cervical (LIE) en adolescentes embarazadas y no grávidas atendidas en la Maternidad Dr. Armando Castillo Plaza de Maracaibo, Venezuela. Método: Investigación comparativa con diseño no experimental transeccional y de campo; donde se incluyeron 46 adolescentes embarazadas (casos) y 46adolescentes no embarazadas (controles), escogidas mediante muestreo probabilístico aleatorio, a quienes se les realizó identificación de factores asociados a la patología, evaluación por citología cervicovaginal y Genotipificación del VPH por reacción en cadena de la polimerasa (PCR). Resultados: se encontró que 32,6% de las embarazadas presentaron LIE de bajo grado (VPH o NIC 1) respecto a 21,7% en las no grávidas, común riesgo dos veces mayor (OR [IC95%]= 2,44 [1,05-5,65]). El diagnóstico molecular resultó positivo en la mitad del total de la muestra, siendo mayor en las embarazadas (52,1 vs. 47,9p<0,05);predominado las infecciones pro genotipos de alto riesgo 47,8vs 30,5; p <0,05). El VPH 16 resulto el más prevalente entre las embarazadas (21,7%) y la co-infección por genotipos debajo riesgo (6-11) en las no grávidas (17,4%) Conclusiones: las embarazadas adolescentes presentan una mayor prevalencia de LIE e infección genital por VPH, asociado a un riesgo significativo del doble de probabilidad de presentar una LIE respecto a las adolescentes no grávidas(AU)

Aim: To compare the presence of Human PapillomaVirus (HPV) and Squamous Intraepithelial Lesion (SIL)in pregnant and non-pregnant adolescents treated at the "Maternidad Dr. Armando Castillo Plaza" in Maracaibo, Venezuela. Patients and Methods: A comparative research with non-experimental transectional and field design was performed; where 46 pregnant adolescents (cases) and 46 non-pregnant adolescents (controls) was included, chosen by random probability sampling, who under went identification off actors associated with the pathology, evaluation by pap-smearand HPV genotyping by chain reaction of polymerase (PCR). Results: It was found that 32.6% of pregnant women had lowgrade SIL ( HPV or CIN 1) compared to 21.7% in non-pregnant women, with a risk twice higher (OR [95% CI] = 2.44 [1.05-5.65]). thee molecular diagnosis was positive in half of the total sample, being higher in pregnant women (52.1 vs. 47.9p <0.05);infections with high-risk genotypes predominated 47.8 vs 30.5;p <0.05). HPV 16 was the most prevalent among pregnant women (21.7%) and co-infection by low-risk genotypes (6-11) in non-pregnant women (17.4%). Conclusions: adolescent pregnant women have a higher prevalence of LIE and genital HPV infection, associated with a significant risk of twice the probability of presenting an LIE compared to non-pregnant adolescents(AU)

Comparative analysis of anal colposcopy with histology in the follow-up of patients under treatment for anal condyloma

Objectives: To compare morphological abnormalities on anal colposcopy against histology to determine anal high-grade squamous intraepithelial lesions (HSILs). Methods: This is a retrospective data assessment of HIV-negative and HIV-positive patients undergoing outpatient follow-up. The sample comprised 54 patients presenting acetowhite lesions on anal colposcopy. Acetowhite lesions were classified according to their morphology into punctation, verrucous, mosaic, ulcerated, or hypervascularized, and biopsies of these specimens were classified as anal HSIL, low-grade squamous intraepithelial lesion (LSIL), or normal. The data were analyzed using SPSS forWindows version 13.0 (SPSS Inc., Chicago, IL, USA). The results were analyzed using the nonparametric Mann-Whitney test, the Fisher exact test and the chi-squared parametric test. A 95% confidence interval (CI) was used and a level of significance <5% was adopted for all statistical tests. Results Fifty-four patients (50 males, 80% HIV+) with biopsied acetowhite lesions were assessed. There were 31 punctation lesions, 1 classified as HSIL (3.2%; 95%CI: 0- 40.0), 17 verrucous lesions, 3 HSIL (17.7%; 95%CI: 0-10.7), and 1 ulcerated, classified as HSIL (100%), and 4 mosaic and 1 atypical vessel lesion, all classified as LSIL. The results showed no association of presence of anal HSIL with positivity for HIV infection or with counts above or below 500/µl in HIV+patients. Statistical analysis was performed using the Mann-Whitney nonparametric test, the Fisher exact test, and the chi-squared parametric test. Conclusion: The comparison of morphological findings on anal colposcopy against histology revealed no morphological pattern suggesting anal HSIL. (AU)

Podem ser tratadas com abordagens conservadoras e procedimentos excisionais. A vacinação anti-HPV e o tratamento excisional oportuno constituem, respectivamente, prevenção primária e secundária contra o câncer do colo uterino.(AU)

Cervical intraephitelial neoplasms correspond to changes identified by cervical citological screening and histological study, post-incisional biopsy guided by colposcopy or excisional diagnostic procedure. They can be treated with conservative approaches and excision procedures. Anti-HPV vaccination and timely excional treatment are primary and secondary prevention against cervical cancer, respectively.(AU)

Value of Endocervical Curettage in Detection of High-grade Cervical Squamous Intraepithelial Lesion / 肿瘤防治研究

Objective To explore the value of endocervical curettage (ECC) in the detection of high-grade cervical squamous intraepithelial lesion (HSIL). Methods We retrospectively analyzed the clinical features and colposcopical characteristics of 678 female patients with complete clinical data. Results Among 678 cases, 391 cases were confirmed by cervical biopsy only and 7 cases by ECC only (57.67% vs. 1.03%, P < 0.001). ECC checked out 287 HSIL patients (42.33%, including cervical biopsy positive and negative cases) and cervical biopsy checked out 671 HSIL cases (98.97%, including ECC positive and negative cases). There were 68 positive ECC cases in the conversion area of Type 1+Type 2 and 247 positive ECC cases in the conversion area of Type 3(33.33% vs. 52.11%, P < 0.001). The positive rates of ECC in patients≥45 years old and < 45 years old were 145 and 170, respectively (55.13% vs. 40.96%, P < 0.001). Conclusion The cervical biopsy plays a dominant role in the detection of HSIL, and ECC can only be used as a supplement to it. Female patients older than 45 years or with Type 3 transformation zone examined by colposcopy should be concerned with cervical lesions.

Lesão intraepitelial de alto grau na gravidez: condutas e achados durante a gravidez e pós-parto / High-grade intraepithelial injury in pregnancy: conduct and findings during pregnancy and post-childhood

Objetivo: Relatar o acompanhamento de gestação planejada, parto e puerpério de paciente em seguimento prévio a gestação de lesão intraepitelial de alto grau (câncer in situ) após realização de conização e reconização, com persistência da lesão. Métodos: Foi realizada análise de prontuário da paciente e comparação da evolução com a bibliografia. Resultados: A paciente foi acompanhada com colpoci- tologia oncológica, desde o diagnóstico de gravidez até o puerpério, apresentando resultados negativos para neoplasia. Conclusão: A decisão da paciente de gestar foi respeitada e ela teve assistência e cuidados durante todo o pré-natal, com seguimento e controle da sua lesão. Tal decisão poderia comprometer seu futuro se a lesão evoluísse. Porém, com a regressão total, pode-se pensar que a paciente poderia ter perdido a oportunidade de gestar, com um desfecho favorável, além de ser submetida a um procedimento cirúrgico definitivo importante, com conse- quências psicológicas.(AU)

Objective: To report on the follow-up of planned pregnancy, childbirth and the puer- perium of a patient who was following the pregnancy prior to pregnancy of a high- -grade intraepithelial lesion (cancer in situ) after conization and reconditioning, with persistence of the lesion. Methods: Analysis of the patient's medical record and com- parison of progress with the bibliography was performed. Results: The patient was followed up with oncological colpocytology, from the diagnosis of pregnancy until the puerperium, showing negative results for neoplasia. Conclusion: The patient's decision to gestate was respected, and she had assistance and care throughout the prenatal period, with follow-up and control of her injury. Such a decision could jeo- pardize your future if the injury evolves. However, with total regression, it can be thought that the patient could have missed the opportunity to gestate, with a favo- rable outcome, in addition to undergoing an important definitive surgical procedure and its psychological consequences.(AU)

Citologia oncótica cervicovaginal na população lésbica e transgêneros / Cervicovaginal oncotic cytology in the lesbian and transgender population

O câncer de colo uterino causa a morte de milhares de mulheres no mundo. Entre essas mulheres, há grupos como o de lésbicas e transgêneros que têm dificuldade no rastreio devido à discriminação e ao desconhecimento. As lésbicas e transgêneros masculinos que não fizeram histerectomia total devem se manter no rastreio da mesma forma que as mulheres cisgêneros. Transgêneros femininos devem ser seguidas, porém ainda não há protocolos definidos.(AU)

Cervical cancer causes the death of thousands of women worldwide. Among these women, there are groups, like lesbians and transgenders that present difficulty in screening due to discrimination and lack of knowledge. The lesbians and transgenders men who didn´t have total hysterectomy, must keeping in screening the same way as cisgenders. Transgender woman must be followed, but there aren't definitive guidelines.(AU)

Evaluation of Swede score and Reid score to improve the predictive value of colposcopy and its correlation with histology

Background: Cervical carcinoma is the second most common malignancy amongst women in India. It is regarded as a public health problem and a priority in cancer control programmes by the WHO. Colposcopy has proven to be very useful in identifying and guiding the biopsy of dysplastic lesion. To minimize inter-observer variation, colposcopic scoring system has been introduced.Methods: A prospective cross- sectional study including 250 women in whom the prevalence of different grades CIN was done. Co-relation of Pap (cytology) with colposcopy scoring system viz. Reid’s and Swede scores, has been made in this study. The two screening methods were compared and their statistical association with histological findings were analyzed.Results: Per speculum examination performed in 250 sexually active women with suspicious looking cervix, belonging to 25-60 years of age, with most common presenting complaints of pain abdomen (38.8%) followed by leucorrhoea, irregular cycles and Post coital bleed. Unhealthy cervix (49.2%) and persistent discharge (28%) were the most common indications for colposcopy. An assessment of both SWEDE score and Reid score as a function of histological findings was done, while Swede score of >5 showed slightly more sensitivity (100%) for diagnosing CIN1+ lesions, Reids score of >5 was more specific (100%) with a higher positive predictive value (100%) for diagnosing  CIN 1, 2, 3 and invasive cervical carcinoma. There was a marked positive association between Reid score and SWEDE score.Conclusions: The colposcopic scoring systems and histopathology showed significant compliance. Predictive accuracy of colposcopy increased with increasing severity of disease.

Analytical study of Pap smear reports over a period of 1 year in a tertiary care centre

Background: Cervical cancer is the fourth most common cancer in women. In India and other developing countries cervical cancer is the leading cause of morbidity and mortality. Cancer cervix continues to be most common genital carcinoma in India accounting for 80% of all female genital malignancies. Pre-invase lesions can spontaneously regress to normal or remain stable for long period or progress to a higher degree of dysplasia. Cancer of cervix is preventable if diagnosed at the pre-invasive stage with regular intervals of cytological screening by Papanicolaou (Pap) smears. The aim of the study is to analyse the pap reports in terms of normal findings, infections, premalignant lesions and invasive cancers.Methods: All women attending the outpatient department gynaecology at TMMC and RC Moradabad, Uttar Pradesh over a period of 1 year from august 2017-18 presented of obstetrics and with white discharge per vagina were screened for cervical cancer using pap smear. All the smears were reported as per the 2014 Bethesda system.Results: Out of 1392 Pap smear reports ASCUS was reported in 27 cases (2%), LSIL in 27 cases (2%), HSIL in 15 cases (1%), malignant cells in 15 cases (1%) and normal including the infection is reported in 1308 cases (94%).Conclusions: Early cervical epithelial changes can be identified by a Pap smear test, which is the primary screening test for detection of precancerous cervical intraepithelial neoplasia and the early stage of invasive cervical cancer.

Experience of cervical Pap smear screening in tertiary care hospital

Background: Cervical cancer is the leading cause of death in women in developing countries like India. It is preventable by regular screening by Pap smear and can be detected at pre-invasive stage. Thus, reducing the morbidity and mortality related with cervical cancers. Objective: This study aims at detecting the prevalence and current trends of various epithelial cell abnormalities (ECAs) in females attending a tertiary care hospital. Materials and Methods: This is a retrospective study conducted in a tertiary care hospital between July 2015 and May 2019. A total of 15,270 cases comprising 11,494 conventional and 3776 liquid-based cytology Pap smears were included in the study. Clinical data and history of the patients were retrieved. All cases were reported according to Bethesda system 2014. Results: Among 15,270 cases, 793 Pap smears were unsatisfactory, 14,153 Pap smears were negative for intraepithelial lesion/malignancy, and 325 cases had ECA. Conclusion: Large hospital-based studies are required for proper implementation of health services and for the selection of a feasible as well as sensitive screening test for early detection of cervical dysplasias which can be helpful in decreasing the burden of cervical cancer in our community.

Value of transformation zone type in the evaluation of random biopsy among patients without visible lesions under colposcopy / 上海交通大学学报（医学版）

Objective: To explore the value of cervical transformation zone (TZ) type in assessing whether a random biopsy should be used to diagnose high-grade squamous intraepithelial lesion (HSIL) among patients without visible lesions under colposcopy. Methods: A total of 517 patients who underwent colposcopy (without visible lesions) due to high risk subtype infection of human papillomavirus (HPV) or thinprep cytologic test (TCT) abnormality were enrolled. TZ types were identified, random biopsies were performed, and the value of TZ type, Ⅱand III in the diagnosis of HSIL was evaluated. Results: There were 517 cases without visible lesions under colposcopy. Three hundred and ninety-six of them were TZ type III, and the detection rate of HSIL was 3.8% (15/396) by random biopsy, while one hundred and twenty one of them were TZ type and Ⅱ, and the detection rate of HSIL was 8.3% (10/121). Compared with the TZ type III, the detection rate of HSIL in the TZ type and Ⅱ was significantly increased (P=0.000). Logistic regression showed that TCT abnormality, TZ type and Ⅱ were the risk factors for HSIL detection in patients without visible lesions under colposcopy. Conclusion: Random multipoint biopsy can significantly increase detection rate of cervical HSIL when no visible lesion is visualized under colposcopy, particularly in women with abnormal TCT results or TZ type and Ⅱ.

Association between asymptomatic sexually transmitted infections and high-risk human papillomavirus in cervical lesions / 西安交通大学学报(医学版)

Objective To determine the association of asymptomatic sexually transmitted infections (STIs) with high-risk human papillomavirus (hrHPV) in cervical squamous intraepithelial lesions and neoplasms. Methods From July 2017 to July 2018, 320 hrHPV-positive and 160 hrHPV-negative women in The First Affiliated Hospital of Xi'an Jiaotong University were divided into normal+low-grade squamous intraepithelial lesion (LSIL) and high-grade squamous intraepithelial lesion (HSIL)+ invasive cervical cancer (ICC) subgroups, respectively, based on their pathological cervical lesion grades. Cervical brush specimens including Ureaplasma urealyticum (UU) and its serotypes, Mycoplasma hominis (MH), Mycoplasma genitalium (MG), Chlamydia trachomatis (CT), and hrHPV were amplified and hybridized using PCR kits (Hybribio Biochemistry Co., Ltd.). The differences between groups were examined by the chi-squared test, continuity correction and Logistic regression. Results The overall infection (at least one of the non-hrHPV pathogens was positive) rates of the two groups were 62.5% and 59.4%, which were not significantly different. The prevalence of UU was the highest. The prevalence of UU serotype 14 (Uup14) and MH was associated with hrHPV (P=0.003, P=0.005, respectively), but not with certain hrHPV genotypes or with single or multiple genotypes. Compared with cases of normal+LSIL, cases of HSIL+ICC had significantly different Uup14 infection rates (OR: 12.579, 95% CI: 3.638-43.497, P<0.001) in the positive group. In hrHPV-negative cases, there were obvious differences in Uuu and Uup1 infections based on different cervical lesion types (OR: 11.646, 95% CI: 1.493-90.850, P=0.019; OR: 7.474, 95% CI: 1.140-49.015, P=0.036). Conclusion Asymptomatic STIs in female lower reproductive tract are widespread. Uup14 may increase the risk of HSIL+ICC when hrHPV is positive. Uuu and Uup1 cause an increased risk of HSIL+ICC without hrHPV.

Characteristics and significance of hr-HPV distribution of HSIL and cervical cancer in Hainan / 公共卫生与预防医学

Objective To explore the characteristics and significance of human papillomavirus (HPV) and high-risk HPV infection in cervical high-grade squamous intraepithelial lesions (HSIL) and cervical cancer (CC) in Hainan, and to provide a reference for the prevention of HPV infection and cervical cancer screening. Methods From May 2017 to December 2019, 379 gynecological inpatients in our hospital were selected (as case group), including 220 cases in the HSIL group and 159 cases in the CC group. A total of 182 healthy females undergoing physical examination in the same period of time were selected as a control group. Using PCR technology and DNA reverse dot hybridization technology, the patients were tested for HPV-DNA subtypes which were divided into 13 high-risk types and 10 low-risk types according to HPV genotypes. The relationship between HSIL and CC of patients and high-risk HPV infection was analyzed. Results (1) The HPV infection rate of HSIL and CC patients in the case group (85.75%) was significantly higher than that in the control group (26.92%) (P50-year-old group were significantly higher than those in other age groups. (4) In both the case group and the control group, single subtype infection was higher than multiple infection (P<0.001). Conclusion HSIL and CC patients in this area are mainly infected with single subtype and high-risk HPV. The infection exhibited certain differences in different ages.

Clinicopathological features of stratified mucin-producing neoplastic lesions of the cervix / 中华病理学杂志

Objective@#To investigatethe clinicopathological features of stratified mucin-producing intraepithelial lesion (SMILE) and invasive stratified mucin-producing carcinoma (ISMC) of the cervix with review of the literature.@*Methods@#Sixteen patients with SMILE/ISMC components of the cervix were collected from files in the Department of Pathology at Xijing Hospital from January 2007 to March 2019. Clinicopathological data included age at diagnosis, clinical presentation, histological type, depth of invasion measurement, the status of lymphovascular space invasion (LVSI) and lymph node metastasis, FIGO staging and follow-up. Histochemistry AB and PAS-D staining and immunostaining for cytokeratin (CK) 7, p16, p63, p40, PAX8, MUC6, p53 were performed simultaneously. In addition, twelve cases with invasive endocervical adenocarcinoma were evaluated using three-tiered pattern-based system (also called Pattern Classification).@*Results@#The average age at diagnosis for patients was 49.7 years (range, 33 to 65 years), and vaginal bleeding occurred in the majority of cases (13/16). The characteristic morphology of SMILE and ISMC was present as non-invasive and invasive stratified epithelium that the full-thickness cells contained different amount of cytoplasmic mucin, respectively. Five cases of SMILE coexisted with adenocarcinoma in situ (1 case), high-grade squamous intraepithelial lesion (1 case), and invasive adenocarcinoma (3 cases). Thirteen cases with ISMC components included pure ISMC (3 cases), mixed with usual-type endocervical adenocarcinoma (8 cases) or squamous cell carcinoma (2 cases). All pure ISMC had lymph vascular space invasion and depth of invasion exceeded 10 mm. All eleven cases of invasive adenocarcinoma with ISMC components belonged to Pattern C tumors, which typically showed diffusely destructive stromal invasion, solid or poorly differentiated components. The results of histochemical staining confirmed that SMILE/ISMC cells were rich in acidic and neutral mucin. The immunohistochemical staining for CK7 and p16 was diffusely strong positive in SMILE (4/4) and ISMC (8/8) components. The positive expressions of p63 and p40 was located in peripheral cells of stratified epithelial nests or merely in a few cells of SMILE (1/3) and ISMC (2/8) components. In ISMC tissues, there were partial expression of MUC6 (5/7), focal expression of PAX8 (2/8), and wild-type expression pattern (4/10) or completely negative expression (6/10) of p53 protein. All thirteen patients with follow-up data were alive (mean 50.5 months, range 4 to 140).@*Conclusions@#As new tumor entities, SMILE is a rare and unique endocervical intraepithelial lesion, while ISMC belongs to an invasive leison. Given that the tumors with ISMC components may have aggressive behavior, it is important for clinicians and pathologists to fully understand the clinicopathological features of SMILE and ISMC.
