RESUMO

PURPOSE: Örebro County introduced an updated screening program 2016 with primary HPV test for women over 30 years and prolonged screening, increasing the cut-off age from 56-60 to 64-70. The aim of this study was to investigate the prevalence of HPV genotypes and their correlation to histological changes in women, 10 years after exclusion from the screening program, due to an eventual implementation of a catch-up program including all women aged 60-70. METHODS: All women in Örebro County, born 1,946 (n = 1,968), were invited to a liquid-based cell sample with primary HPV screening. Samples were analyzed for hrHPV mRNA and positive samples were genotyped. hrHPV positive women were offered to do a conization. RESULTS: Out of 809 participants, 31 (3.8%) were hrHPV positive, of these 22 did a conization. Histologically, 5/22 (23%) had LSIL and 5/22 (23%) had HSIL. Normal histology was found in 12/22 (55%). The most prevalent genotypes were HPV 16, 33, 52, 56, and 68. Of the women with HSIL, one case of cervical cancer was confirmed in a recone biopsy after 4 months. CONCLUSION: The study showed considerable prevalence of hrHPV and histologically confirmed LSIL/HSIL. These data led to catch-up screening for women between 60 and 70 years when overlapping two screening strategies.

RESUMO

OBJECTIVE: Surgical technique for loop electrosurgical excision procedure (LEEP) and cold knife cone (CKC) emphasizes a uniform specimen, but sequelae of specimen fragmentation are not established. We evaluated outcomes between fragmented and unfragmented excisional biopsy specimens. MATERIALS AND METHODS: Loop electrosurgical excision procedure and CKCs from January 2010 to October 2013 were reviewed. Intraepithelial lesion grade, fragmentation, margin, and Endocervical curettage status were analyzed. Adenocarcinoma in situ and cancer were excluded. Repeat procedures during the study period were included in follow-up. Loop electrosurgical excision procedures with top hat with no separate fragments were analyzed independently versus those with fragmented LEEP and/or top hat. Indeterminate margin was defined as inconclusive or unevaluable margin, or intraepithelial lesion in unidentifiable margin or fragment. Outcomes involved residual or recurrent disease and repeat procedures for intraepithelial lesion. χ was used for statistical analysis. RESULTS: Fragmented specimens were more likely to have any positive margin (p = .01), multiple positive margins (p < .001), and indeterminate margin (p < .001) than unfragmented specimens. There was no significant difference in rates of positive, insufficient, or high-grade Endocervical curettage (p = .74, 0.54, 0.92). Patients with fragmented specimens were more likely to have high-grade lesion recurrence in the following 3 years (p = .04) versus patients with index unfragmented specimens, though not compared with those with unfragmented LEEP + top-hat cases. Overall rates of repeat LEEP/CKC or hysterectomy for dysplasia were not different (p = .56). CONCLUSIONS: Fragmentation of LEEP and CKC specimens is associated with higher rates of positive margins, recurrent high-grade intraepithelial lesions, and indeterminate margins. These may cause diagnostic uncertainty, require closer follow-up, and increase cost with more visits and studies.

RESUMO

AIMS: The purpose of the present study was to elucidate the presence of human herpesvirus 6A (HHV-6A), HHV-6B and HHV-7 in samples of the uterine cervix through detection of viral DNA. We analysed normal tissues, samples with low-grade squamous intraepithelial lesions (LSILs) and high-grade squamous intraepithelial lesions (HSILs). We correlated the presence of HHV-6 and HHV-7 with the finding of human papillomavirus (HPV) in mucosal samples. METHODS: Cervical samples were examined and grouped as follows: group 1 (n=29), normal cytology; group 2 (n=61), samples with LSIL; group 3 (n=35), samples with HSIL. Molecular biology examinations were performed in all samples to detect HHV-6, HHV-7 and HPV DNA and to typify HHV-6 species. RESULTS: Group 1: normal cytology and HPV (-): HHV-6: 6.8% (2/29), HHV-7: 79.3% (23/29); group 2: LSIL and HPV (-): HHV-6: 93.1% (27/29), HHV-7: 96.5% (28/29); LSIL and HPV (+): HHV-6: 0% (0/32), HHV-7: 90.6% (29/32); group 3: HSIL and HPV (-): HHV-6: 20% (2/10), HHV-7: 70% (7/10); HSIL HPV (+): HHV-6: 12% (3/25), HHV-7: 68% (17/25). HHV-6A DNA was not detected in any samples. CONCLUSIONS: (1) Both HHV-6 and HHV-7 infect the mucosal cells of the cervix with higher prevalence of HHV-7. (2) The higher prevalence of HHV-6 in LSIL HPV (-) samples compared with those with normal cytology indicates that it constitutes a possible risk factor for atypia production. (3) The presence of HHV-7 in all samples questions its role in the production of atypia. (4) The finding of HHV-6 and HHV-7 suggests that the cervical mucosa is a possible transmission pathway for these viruses.

RESUMO

Objetivo: Estudio prospectivo a lo largo de 4 meses de las ITS (infecciones de trasmisión sexual) en mujeres diagnosticadas de ASCUS (atipias de las células escamosas de significado incierto) y LSIL (lesión escamosa intraepitelial de bajo grado) en la citología cervicovaginal en medio líquido. Diseño: Estudio de edad, paridad, abortos, nuligestas, fumadoras, métodos contraceptivos, antecedentes personales, citología, análisis de VPH-AR (virus del papiloma humano de alto riesgo) e ITS mediante RCP (reacción en cadena de la polimerasa, PCR en inglés) para Chlamydia trachomatis, Neisseria gonorrhoeae, Mycoplasma genitalium, Mycoplasma hominis, Ureaplasma urealyticum, Ureaplasma parvum y Trichomonas vaginalis. Resultados: La serie consta de 65 casos: 36 ASCUS y 29 LSIL. No hubo diferencias significativas en ningún parámetro entre ambos grupos. Las medias de edad fueron de 36,02 y 35,77 años, respectivamente. La paridad media fue 0,61 y 0,55 partos, respectivamente. Eran nuligestas el 44,44 y 48,27%, respectivamente. No hacían contracepción el 55,35 y 65,51%, respectivamente. Eran fumadoras el 25% en ASCUS y el 27,58% en LSIL. Hubo VPH negativo en el 41,66% en ASCUS y en el 31,03% en LSIL. El VPH-AR (+) se dio en el 68,33% en ASCUS y en el 68,96% en LSIL. Los VPH-AR más frecuentes fueron: otros de AR en el 50% en ASCUS y en el 62,06% en LSIL. VPH(+) e ITS (+) ocurrió en el 44,44% en ASCUS y en el 58,62% en LSIL, sin diferencias. El análisis para ITS fue negativo en el 30,55% en ASCUS y en el 20,68% en LSIL. Hubo más gérmenes detectados en el grupo LSIL, con diferencia significativa (p<0,05) para Gardnerella vaginalis, 17,24% en LSIL frente a 2,77% en ASCUS. Los gérmenes más frecuentes fueron: U. urealyticum en el 13,88% en ASCUS y en el 24,13% en LSIL; y U. parvum en el 36,11% en ASCUS y en el 44,82% en LSIL. Conclusion: El análisis de ITS es primordial, junto con la citología y el VPH, para detectar infecciones, a tratar, para poder regresar a la normalidad citológica

RESUMO

BACKGROUND: Women living with HIV (WLWH) have high rates of persistent high-risk human papillomavirus (hrHPV) infections and cervical cancer. We aimed to assess the distribution of hrHPV genotypes, risk factors of type-specific hrHPV persistence, and high-grade squamous intraepithelial lesions or worse (≥HSIL) in WLWH in Denmark. METHODS: From the prospective Study on HIV, cervical Abnormalities and infections in women in Denmark (SHADE) we identified WLWH with a positive hrHPV test during the study period; 2011-2014. HIV demographics were retrieved from the Danish HIV Cohort Study and pathology results from the The Danish Pathology Data Bank. Logistic regression was used to identify risk factors associated with persistent hrHPV infection (positivity of the same hrHPV type in two samples one-two years after the first hrHPV positive date) and ≥ HSIL. RESULTS: Of 71 WLWH, 31 (43.7%) had persistent hrHPV infection. Predominant hrHPV genotypes were HPV58, 52, 51, and 35 and most frequently observed persistent genotypes were HPV52, 33 and 31. CD4 < 350 cells/µL predicted genotype-specific hrHPV persistence (adjusted OR 4.36 (95%CI: 1.18-16.04)) and ≥ HSIL was predicted by prior AIDS (adjusted OR 8.55 (95% CI 1.21-60.28)). CONCLUSIONS: This prospective cohort study of well-treated WLWH in Denmark found a high rate of persistent hrHPV infections with predominantly non-16/18 hrHPV genotypes. CD4 count < 350 cells/µL predicted hrHPV persistence, while prior AIDS predicted ≥HSIL.

RESUMO

OBJECTIVE: To determine the prevalence of anal HPV genotypes and associated factors in women with pre-malignant lesion or cancer in the cervix and anal canal. METHODS: A prospective, cross-sectional study analyzed DNA samples taken from women with cervical pre-malignant lesions or cancer to identify anal HPV by polymerase chain reaction (PCR). The prevalence of high-risk HPV (HR-HPV) in women with intraepithelial neoplasia and anal cancer was calculated; sociodemographic and clinical risk factors were identified using multivariate analysis. RESULTS: A total of 152 patients were included (mean age 37.8 ± 10.01 years), of whom 101 (66.4%) had anal HR-HPV. Fourteen different anal HPV types were identified. HPV 16 and 18 were found in 30 (52.6%) anal high-grade squamous intraepithelial lesions (HSIL), and HPV 31 and 33 in 21 (36.8%) lesions. In the logistic regression analysis, the factors that remained associated with HR-HPV types were: an anal histopathology report of HSIL or invasive carcinoma (odds ratio [OR] 8.96, 95% confidence interval [CI] 3.40-23.57; P<0.0001) and alcohol consumption (OR 2.20, 95% CI 1.01-4.80; P=0.04). CONCLUSION: Prevalence of HR-HPV is high in the anal canal of women with cervical and anal pre-malignant lesions simultaneously or cancer of the cervix and/or anal canal. HPV 16, 31, 33, and 18 were the four major genotypes identified.

RESUMO

Objective: To analyze the performance of colposcopy and investigate the diagnosis and treatment characteristics of high-grade squamous intraepithelial lesion (HSIL) diagnosed by cervical tissue sampling in post-menopausal women. Methods: A retrospective study was performed on 1 449 patients with HSIL diagnosed by cervical tissue sampling under colposcopy and treated by loop electrosurgical excision procedure (LEEP) or extrafascial hysterectomy as the primary therapy at the First Affiliated Hospital of Nanjing Medical University, from November 2015 to October 2017. In order to investigate the diagnosis and treatment of HSIL in post-menopausal women, a case-control study was conducted to compare the difference in performance of colposcopy and treatment modality between 213 post-menopausal patients (14.7%, 213/1 449) and 1 236 pre-menopausal patients (85.3%, 1 236/1 449). Results: (1)The proportion of cases pathologically upgraded to cervical cancer was significantly greater in post-menopausal patients (9.4%, 20/213) compared with pre-menopausal patients (3.8%, 47/1 236; P<0.05). (2) The proportion of ≥HSIL diagnosed by colposcopy showed no significant difference between post-menopausal patients (76.1%, 162/213) and pre-menopausal patients (78.2%, 967/1 236; P=0.479). The proportion of type Ⅲ transformation zone (TZ) was significantly greater in post-menopausal patients (91.1%, 194/213) compared with pre-menopausal patients (59.1%, 731/1 236; P<0.05). The rate of missed diagnosis of cervical cancer was significantly higher in type Ⅲ TZ (6.4%, 59/925) compared with type Ⅰ and(or) Ⅱ TZ (1.5%, 8/524; P<0.05). The proportion of HSIL detected by endocervical curettage alone was greater in post-menopausal patients (9.9%, 21/213) compared with pre-menopausal patients (2.6%, 32/1 236; P<0.05). (3)Initial treatment with LEEP: the positive rate of endocervical margin was significantly greater in post-menopausal patients (20.5%, 36/176) compared with pre-menopausal patients (10.5%, 130/1 236;P<0.05); in patients who were diagnosed as HSIL after LEEP, the positive rate of endocervical margin and the residual rate were both greater in post-menopausal patients compared with pre-menopausal patients [15.4% (25/162) versus 8.8% (105/1 189), P=0.008; 52.0% (13/25) versus 26.7% (28/105), P=0.014]. (4)Thirty-seven post-menopausal patients were treated by extrafascial hysterectomy as the primary therapy, 5 cases (13.5%, 5/37) were diagnosed as cervical cancer (stage Ⅰa1) after the surgery. Conclusions: (1) The lesions of HSIL in post-menopausal patients still have definite features under colposcopy as same as pre-menopausal patients. Endocervical curettage could help detect more HSIL in post-menopausal patients. Compared with pre-menopausal patients, post-menopausal HSIL patients have an increased risk of cervical cancer and are more likely missed by cervical tissue sampling. (2) LEEP has the dual effects of diagnosis and treatment, and is still the recommended treatment for post-menopausal HSIL patients. However, the increase in positive rate of endocervical margin and residual rate requires further active intervention. (3) Considering those post-menopausal HSIL patients who cannot accept conization as the initial treatment, the selection of hysterectomy type requires more thorough study.

RESUMO

PURPOSE: FOXP3 is a marker of the T regulatory (Treg) cell subset and drives its function and homeostasis. Its expression maintains the host immunosuppressive state that favors persistence of human papillomavirus (HPV) infection and squamous intraepithelial lesion (SIL) appearance. The present study evaluated the effects of the rs3761548 and rs2232365 intronic single-nucleotide variants (SNVs) and their haplotypes on HPV infection and SIL diagnosis in HPV-infected and -uninfected women. METHODS: HPV DNA-based detection in cervical specimens was performed by PCR. FOXP3 variants were genotyped by PCR-restriction fragment length polymorphism and haplotype recombination sites were inferred for 208 HPV-infected and 218 HPV-uninfected women diagnosed or not with low- or high-grade intraepithelial lesions of cervix. Case-control analyses were carried out by logistic regression adjusted for several socio-demographic, sexual lifestyle, and clinical data. RESULTS: The homozygous genotype of the rs3761548 variants (A/A) (related to decreased FOXP3 expression) may exert a protective role against HPV infection in women (ORAj: 0.60; 95% CI 0.36-0.99; p = 0.049) and was an independent predictor of protection against HSIL development (ORAdj: 0.28; 95% CI 0.11-0.68; p = 0.006). In addition, the homozygous genotype (G/G) of the rs2232365 variants (related to increased FOXP3 expression) was independently associated with the HPV infection (ORAdj: 2.10; 95% CI 1.06-4.15; p = 0.033). Haplotype analysis revealed no significant associations in our study. CONCLUSIONS: Our results reveal the significant and independent associations between FOXP3 genetic variants and susceptibility to HPV infection and SIL diagnosis and their role as biomarkers of HPV infection and cervical lesion management.

RESUMO

BACKGROUND: DNA methylation has been suggested as one of the epigenetic changes promoting carcinogenesis. The aim of this study was to prospectively evaluate the methylation status of CADM 1, MAL and hsa-miR-124 genes in high-grade squamous intraepithelial lesion (HSIL) liquid-based cytology (LBC) samples with a histological correlation. METHODS: Seventy histologically confirmed cases of HSIL paired with prior screening LBC diagnosis of HSIL within a 3-month interval were selected. Histologically, the lesions were reviewed and assessed including: (a) number of blocks harbouring dysplastic squamous epithelium; (b) number of blocks containing glandular extension of dysplastic epithelium; and (c) the depth of glandular extension (which was assessed semi-quantitatively as graded 1-3). Human papillomavirus (HPV) subtyping was performed from residual LBC materials using the LINEAR ARRAY HPV Genotyping Test and in-house polymerase chain reaction targeting the HPV E1 gene. The detection of methylation silencing of tumour suppressor genes CADM1, MAL and hsa-miR-124 was performed by multiplex methylation-specific real-time polymerase chain reaction. RESULTS: A positive methylation status was detected in 41 cases (58.6%). The number of blocks with HSIL varied from one to 13. Glandular extension was seen in 44 cases with the number of blocks involved ranging from one to 10. The depth of HSIL glandular extension varied. CONCLUSION: The DNA methylation test allows HSIL lesions to be divided into two distinct groups of methylated HSIL in significantly older patients and unmethylated HSIL in younger patients. This study was not able to prove that methylation status in cervical HSIL correlates with the size of the lesion (measured by the number of blocks involved) or with HSIL propensity for endocervical glandular extension, nor with HPV type or multi-infection.

RESUMO

OBJECTIVE: To retrospectively analyse the incidence of high-grade squamous intraepithelial lesions (HSILs) and squamous cell carcinoma (SCC) in women of different ages with high-risk (HR) human papillomavirus (HPV) but with normal cytology test results stratified by age and HPV genotype. METHODS: In total, 1858 women with HR-HPV infection but with a normal smear who received a colposcopy and biopsy between 2015 and 2016 at our institution were included. The pathological results were retrospectively analysed after stratifying by age and HPV genotype. RESULTS: Among the 1858 cases, the HSIL% in women aged 21-29 years (10.54%) was significantly different from that in women aged 40-49 years (19.85%; P < 0.05), whereas there was no significant difference in the HSIL% among women aged 21-29 years and those in the other age groups (P > 0.05). In total, 295 cases had single HPV16 infection. The HSIL% in patients with HPV16/18 infection was >15%, and the 40-49-year age group had the highest percentage at 48.48%. For other HR-HPV infections, the HSIL and SCC incidence rate was 10.41%, and there was no significant difference among the age groups; thus, women with other types of viral infections, regardless of age, should be referred to colposcopy. CONCLUSIONS: Although HPV16 is the HPV with the highest risk, other HR-HPV infections can also cause a high percentage of HSILs and SCC in women with normal cytology. Therefore, it is necessary to refer HR-HPV-infected women aged ≥21 years for colposcopy in a timely manner to exclude potential cervical intraepithelial neoplasia and cervical cancer.

RESUMO

Introduction: India fights massive cervical cancer burden. This article highlights an innovative feasible approach enabling tertiary hospitals to contribute to cancer prevention without compromising their primary mandate to provide treatment. Methodology: Since 1979, National Institute of Cancer Prevention and Research (NICPR) support a tertiary hospital in cervical cancer screening through a satellite clinic. Record review of 5328 attendees of this clinic between January-December 2016 was done. Pap-smear testing and reporting were performed by trained NICPR personnel. Patients' demographics, reproductive history, Pap-test date, cytology results were recorded and results were communicated to respective units for further management. Results: Among 5328 women screened, 2% (96/5328) had abnormal cytology, which included malignancy(33%; 32/96), Atypical Squamous Cells-Undetermined Significance(ASC-US) (20%; 19/96), Atypical Glandular Cells(AGC) (23%; 22/96) with complaints of pain in lower abdomen 65.6%(59/90), white discharge per vaginum 46.7%(42/90) and backache 23.3%(21/90). In which, Muslims- 67% (65/96), illiterates- 58% (56/96). Age>35(p<0.001), parity>3(p<0.05), illiteracy (p<0.05), Muslim women (p<0.05) had positive association with abnormal cytology. Conclusion: Awareness about cervical cancer screening is the immediate need in resource-limited countries. Government hospitals in such countries should house dedicated preventive oncology unit for cancer screening.

RESUMO

Cervical cancer is a major worldwide health problem. Therefore, regular cervical screening in order to make an early diagnosis can help to prevent cervical cancer, through identifying and treating preinvasive cervical lesions. The aim of this review is to evaluate the correlation between the cytological screening result and the final gold standard histological outcome in the diagnosis of cervical lesions. More specifically, the correlation between high-grade intraepithelial lesion (HSIL) on cytology and histological cervical intraepithelial neoplasia grade 2 or higher (CIN2+) was intended, by calculating the positive predictive value (PPV). PPV is an important value from a clinical point of view. An electronic search was carried out in the electronic databases MEDLINE (through PubMed) and the Cochrane Library (last searched beginning of December 2017), supplemented with the related article feature in PubMed and snowballing. Article selection (predefined inclusion and exclusion criteria) and data extraction were evaluated by two independent reviewers (N.K. and A.V.L.). After identifying 1,146 articles, 27 articles were finally included in this systematic review, representing 28,783 cytological HSIL diagnoses in total. The PPV of HSIL was 77.5% (range: 45.4-95.2%) for the histological diagnosis of CIN2+ and 55.4% (range: 36.4-67.6%) for the diagnosis of CIN3+. In this systematic review, 77.5% of the HSIL-positive women eventually had a CIN2+ diagnosis. The diagnostic value of a cytological HSIL result (conventional or liquid-based cytology) in the diagnosis of CIN2+ lesions is good, but a combination of tests could raise this value.

RESUMO

OBJECTIVES: The aim of the study was to evaluate the performance of a folate receptor-mediated tumor detection (FRD) assay for detection of cervical high-grade lesions. MATERIALS AND METHOD: A total of 1504 patients with abnormal cytology and/or positive human papillomavirus (HPV) testing during primary screening from November 2014 to August 2015 were enrolled. The patients were recruited from the Peking University People's Hospital and 12 other hospitals. Folate receptor-mediated tumor detection was applied in all the patients before colposcopy to compare the detection rate, sensitivity, specificity, positive predictive value, negative predictive value, and coincidence rate with HPV and cytology tests according to the pathologic diagnosis. RESULTS: In the total of 1504 patients, 503 patients were negative for intraepithelial lesion or malignancy, 440 patients were cervical intraepithelial neoplasia (CIN) 1, 254 patients were CIN 2, 257 patients were CIN 3, 46 patients were squamous cell carcinoma, and 4 patients were adenocarcinoma in situ. The sensitivity of FRD was 77.72%, which was less than cytology (80.39%) and HPV testing (95.54%). The specificity of FRD was 60.02%, which was greater than cytology (30.12%) and HPV testing (14.95%). The coincidence rate of FRD to the pathologic diagnosis (66.62%) was also significantly greater than atypical squamous cells of undetermined significance cytology and above (48.87%) and HPV testing (45.01%, p < .0001). The detection rate of FRD for all grades of lesions increased with the severity of lesions. CONCLUSIONS: Folate receptor-mediated tumor detection has a slightly lower sensitivity and a higher specificity than cytology and HPV testing for detection of CIN 2+. Simplicity of FRD requires less professional skill. Folate receptor-mediated tumor detection could be a candidate test for cervical cancer screening especially in low- and middle-income countries. However, FRD still needs more clinical trial data to demonstrate its ability in general screening population.

RESUMO

BACKGROUND: To the authors' knowledge, published studies reporting on the performance of the FocalPoint GS (FPGS) imaging system have yielded conflicting results to date. However, the results of the MAVARIC study indicated that the FPGS "No Further Review" (NFR) aspect of the technology demonstrated potential and warranted further investigation. The current validation study was performed prior to implementing the NFR slide reporting technology within the routine cervical screening program in Wales, United Kingdom. METHODS: A total of 45,317 SurePath liquid-based cytology cervical screening samples were submitted for FPGS scanning by 4 Welsh laboratories between 2006 and 2011. The current study (Computer Assisted Evaluation, Screening and Reporting [CAESAR]), reports on a comparison between slides categorized as NFR (8130 slides) and slides manually screened as negative (93,473 slides). Both interventions had a subsequent negative quality control screen. RESULTS: The histological outcome rates of cervical intraepithelial neoplasia 2 (CIN-2) (high-grade squamous intraepithelial lesion or worse [HSIL+]) at 2 years and subsequently 3 years after an FPGS NFR result versus a manually screened negative result were compared. Significantly fewer cases were detected in the NFR cohort compared with the manually screened cohort (P = .043 at 2 years and P = .027 at 3 years). When these cases were subcategorized as cancers and precancers, the interval cancer prevalence between NFR and manually screened samples at 2 years and 3 years was similar; however, the interval precancer prevalence for FPGS NFR was significantly lower (P = .023 at 2 years and P = .026 at 3 years) at approximately one-half that of manual screening. CONCLUSIONS: The negative predictive potential of the FPGS NFR technology is higher than that of manual screening, and the technology has quality/throughput benefits to support and enhance a laboratory cervical screening service.

RESUMO

OBJECTIVES: The paper assess the relevance of HR HPV E6/E7 mRNA test in women with abnormal Pap results. MATERIAL AND METHODS: Between 2013-2014, 125 women were subjects to the enhanced diagnostics due to abnormal Pap results. According to The Bethesda system, if ASC-US, AGC, LSIL, ASC-H, HSIL or cancer cells were present, the result was abnormal. The patients underwent the enhanced diagnostics which included the following procedures: Pap smear collection for molecular assessment of HR HPV E6/E7 mRNA test, the colposcopic examination and biopsy of clinically suspicious areas. RESULTS: High-grade squamous intraepithelial lesions constituted the most frequent cervical pathology in women with abnormal Pap test results, as well as with the positive results of HR HPV E6/E7 mRNA test. Test sensitivity in patients with the histopathological diagnosis of high-grade squamous intraepithelial lesion was estimated at 86.1%. CONCLUSIONS: HR HPV E6/E7 mRNA test identifying neoplastic lesions and cervical cancer is characterised by a high relevance which is reflected by means of sensitivity and specificity. In fact, test sensitivity and specificity increased with the age in the group of patients up to 50 years old.

RESUMO

EXECUTIVE SUMMARY: The risk of cervical cancer (CC) among women immunosuppressed for a variety of reasons is well documented in the literature. Although there is improved organ function, quality of life and life expectancy gained through use of immunosuppressant therapy, there may be increased long-term risk of cervical neoplasia and cancer and the need for more intense screening, surveillance, and management. Although guidance for CC screening among HIV-infected women (see Table 1) has been supported by evidence from retrospective and prospective studies, recommendations for CC screening among non-HIV immunosuppressed women remains limited because quality evidence is lacking. Moreover, CC screening guidelines for HIV-infected women have changed because better treatments evolved and resulted in longer life expectancy.The objective of this report was to summarize current knowledge of CC, squamous intraepithelial lesions, and human papillomavirus (HPV) infection in non-HIV immunocompromised women to determine best practices for CC surveillance in this population and provide recommendations for screening. We evaluated those with solid organ transplant, hematopoietic stem cell transplant, and a number of autoimmune diseases.A panel of health care professionals involved in CC research and care was assembled to review and discuss existing literature on the subject and come to conclusions about screening based on available evidence and expert opinion. Literature searches were performed using key words such as CC, cervical dysplasia/squamous intraepithelial lesion, HPV, and type of immunosuppression resulting in an initial group of 346 articles. Additional publications were identified from review of citations in these articles. All generated abstracts were reviewed to identify relevant articles. Articles published within 10 years were considered priority for review. Reviews of the literature were summarized with relevant statistical comparisons. Recommendations for screening generated from each group were largely based on expert opinion. Adherence to screening, health benefits and risks, and available clinical expertise were all considered in formulating the recommendations to the degree that information was available. RESULTS: Solid Organ Transplant: Evidence specific for renal, heart/lung, liver, and pancreas transplants show a consistent increase in risk of cervical neoplasia and invasive CC, demonstrating the importance of long-term surveillance and treatment. Reports demonstrate continued risk long after transplantation, emphasizing the need for screening throughout a woman's lifetime.Hematopoietic Stem Cell Transplant: Although there is some evidence for an increase in CC in large cohort studies of these patients, conflicting results may reflect that many patients did not survive long enough to evaluate the incidence of slow-growing or delayed-onset cancers. Furthermore, history of cervical screening or previous hysterectomy was not included in registry study analysis, possibly leading to underestimation of CC incidence rates.Genital or chronic graft versus host disease is associated with an increase in high-grade cervical neoplasia and posttransplant HPV positivity.Inflammatory Bowel Disease: There is no strong evidence to support that inflammatory bowel disease alone increases cervical neoplasia or cancer risk. In contrast, immunosuppressant therapy does seem to increase the risk, although results of observational studies are conflicting regarding which type of immunosuppressant medication increases risk. Moreover, misclassification of cases may underestimate CC risk in this population. Recently published preventive care guidelines for women with inflammatory bowel disease taking immunosuppressive therapy recommend a need for continued long-term CC screening.Systemic Lupus Erythematosus and Rheumatoid Arthritis: The risk of cervical high-grade neoplasia and cancer was higher among women with systemic lupus erythematosus than those with rheumatoid arthritis (RA), although studies were limited by size, inclusion of women with low-grade neoplasia in main outcomes, and variability of disease severity or exposure to immunosuppressants. In studies designed to look specifically at immunosuppressant use, however, there did seem to be an increase in risk, identified mostly in women with RA. Although the strength of the evidence is limited, the increase in risk is consistent across studies.Type 1 DM: There is a paucity of evidence-based reports associating type 1 DM with an increased risk of cervical neoplasia and cancer. RECOMMENDATIONS: The panel proposed that CC screening guidelines for non-HIV immunocompromised women follow either the (1) guidelines for the general population or (2) current center for disease control guidelines for HIV-infected women. The following are the summaries for each group reviewed, and more details are noted in accompanying table:Solid Organ Transplant: The transplant population reflects a greater risk of CC than the general population and guidelines for HIV-infected women are a reasonable approach for screening and surveillance.Hematopoietic Stem Cell Transplant: These women have a greater risk of CC than the general population and guidelines for HIV-infected women are a reasonable approach for screening. A new diagnosis of genital or chronic graft versus host disease in a woman post-stem cell transplant results in a greater risk of CC than in the general population and should result in more intensive screening and surveillance.Inflammatory Bowel Disease: Women with inflammatory bowel disease being treated with immunosuppressive drugs are at greater risk of cervical neoplasia and cancer than the general population and guidelines for HIV-infected women are a reasonable approach for screening and surveillance. Those women with inflammatory bowel disease not on immunosuppressive therapy are not at an increased risk and should follow screening guidelines for the general population.Systemic Lupus Erythematosus and Rheumatoid Arthritis: All women with systemic lupus erythematosus, whether on immunosuppressant therapy or not and those women with RA on immunosuppressant therapy have a greater risk of cervical neoplasia and cancer than the general population and should follow CC screening guidelines for HIV-infected women. Women with RA not on immunosuppressant therapy should follow CC screening guidelines for the general population.Type 1 Diabetes Mellitus: Because of a lack of evidence of increased risk of cervical neoplasia and cancer among women with type 1 DM, these women should follow the screening guidelines for the general population.

RESUMO

Cervical cancer is a leading cause of death among women in low- and middle-income countries, and women living with HIV are at high risk for cervical cancer. The objective of this study was to estimate the prevalence and correlates of cervical cancer and pre-cancer lesions and to examine cervical cancer knowledge among women living with HIV receiving antiretroviral therapy in rural Andhra Pradesh, India. We conducted cytology-based screening and administered a standardized questionnaire among 598 HIV-infected women. We found 5 (0.8%), 39 (6.5%), 29 (4.9%), and 4 (0.7%) had atypical squamous cells of undetermined significance (ASCUS), low-grade squamous intraepithelial lesion (LSIL), high-grade squamous intraepithelial lesion (HSIL), and squamous cervical carcinoma (SCC), respectively. In multivariable logistic regression analysis, ASCUS/LSIL was independently associated with age >16 years old at first sexual encounter and smokeless tobacco use. We found no factors associated with HSIL/SCC. In total, 101 women (16.9%) had heard of cervical cancer and 28 (27.7%) of them correctly identified HIV infection as a risk factor. In light of the high prevalence of pre-cancer lesions and low level of cervical cancer knowledge in our study population, focused interventions are needed to improve cervical cancer literacy and prevention among rural women living with HIV.

RESUMO

Background: Adenocarcinoma in situ (AIS) of the uterine cervix is a preinvasive lesion of the invasive adenocarcinoma. We analyzed the cervical screening results leading to detecting the AIS lesions including the coexistence of AIS lesions with high-grade squamous intra-epithelial lesions (HSIL) and invasive carcinoma. Methods: Women who were diagnosed and received treatment for AIS at Chiang Mai University Hospital between January 1, 2007 and August 31, 2016 were retrospectively reviewed. The inclusion criteria were the women who had pathological diagnosis of AIS obtained from cervical punch biopsy or excisional cone biopsy with either loop electrosurgical excision procedure (LEEP) or cold-knife conization (CKC). The patient characteristics, diagnostic work-up and treatment details were reviewed, including the cervical screening results prior to the diagnosis of cervical AIS, pathologic results of excisional cone biopsy and hysterectomy specimens. Results: During the study period, 75 women with AIS pathology undergoing excisional cone biopsy with either LEEP (n=62) or CKC (n=13) were identified. The abnormal cytologic screening leading to detection of AIS was the squamous cell abnormality accounting for 57.3%. Abnormal glandular cytology accounted for 37.3%. The most common abnormal cervical screening results was HSIL cytology (n = 25) followed by AIS cytology (n = 13). Normal cytology was noted in 4 women in whom 3 were positive for HPV 18 and 1 had AIS on the endocervical polyp. AIS coexisted with HSIL and invasive carcinoma were detected in cone biopsy specimens in 21 (28%) and 29 (38.7%) patients, respectively. Conclusion: The majority of cervical screening results leading to detection of cervical AIS was the squamous cell abnormality accounting for 57.3% in which, HSIL cytology was the most common. Abnormal glandular cytology accounted for only 37.3%. Diagnostic cone excision is recommended if AIS lesion is noted in cervical biopsy specimen since nearly 40% have coexisting invasive lesions.

RESUMO

OBJECTIVE: The aim of the study was to evaluate the association between colposcopic features, age, menopausal status, and overtreatment in women subjected to "see-and-treat" approach, to identify subgroups of patients in which this approach could be more appropriate. MATERIALS AND METHODS: Retrospective multicentric cohort study conducted on women older than 25 years, with a high-grade squamous cytological report and a visible squamocolumnar junction, in which colposcopy and the excisional procedure were performed at the same time without a previous cervical biopsy (see and treat). Overtreatment was defined as histopathological finding of cervical intraepithelial lesion grade 1 or normal tissue. RESULTS: Among the 254 included patients, the overall overtreatment rate was 12.6%, whereas in women with a grade 2 colposcopy, it was 3.2% and, in women with grade 1 colposcopy, it was 22.0%. Among the considered factors (age, menopause, and grade 1 colposcopy), only a positive association with overtreatment and grade 1 colposcopy emerged (odds ratio = 8.70, 95% CI = 2.95-25.62, p < .001). CONCLUSIONS: See and treat may be appropriate in women older than 25 years with a visible squamocolumnar junction and a high-grade squamous cervical cytology. Patients need to be informed about the higher risk of overtreatment in case of a grade 1 colposcopic impression, which however may still be considered acceptable. Patient's age and menopausal status should not influence the decision to propose a see-and-treat approach.

RESUMO

BACKGROUND: Low-grade squamous intraepithelial lesion/cervical intraepithelial neoplasia grade 1 (LSIL/CIN1) preceded by colposcopy guided biopsy is recommended conservative follow-up, although some of these lesions are actually high-grade lesions, which are missed on an initial colposcopy. Therefore, in this work, we evaluate the potential role of miRNA detection in cervical exfoliated cells in a clinic-based population for predicting missed high-grade lesions in women diagnosed with LSIL/CIN1 after colposcopy-guided biopsy. METHODS: A total number of 177 women with a diagnosis of LSIL/CIN1 obtained by colposcopy-guided biopsy were grouped into two categories according to the histology of the conization specimens: consistent LSIL/CIN1 group (surgical pathology consistent with colposcopic diagnosis) and missed high-grade lesion group (surgical pathology found high-grade lesion). The expression of eight miRNAs, such as miRNA195, miRNA424, miRNA375, miRNA218, miRNA34a, miRNA29a, miRNA16-2, and miRNA20a was detected by real time-quantitative polymerase chain reaction (RT-qPCR) in cervical exfoliated cells of the 177 patients. Pearson Chi-Square was used to compare the performance efficiency of patients' characteristics. Nonparametric Man-Whitney U test was used to assess differences in miRNA expression. The receiver operating characteristic (ROC) curve was used to assess the performance of miRNA evaluation in detecting missed high-grade lesions. RESULTS: Among the 177 women with biopsy-confirmed CIN1, 15.3% (27/177) had CIN2+ in the conization specimen (missed high-grade lesion group) and 84.7% (150/177) had CIN1-(consistent LSIL/CIN1 group). The relative expression of miRNA-195 and miRNA-29a in the missed high-grade lesion group was significantly lower than that in the consistent LSIL/CIN1 group. The relative expression of miRNA16-2 and miRNA20a in the missed high-grade lesion group was significantly higher than that in the consistent LSIL/CIN1 group. No significant difference was observed between these two groups regarding the other four miRNAs. Of these significant miRNAs, miRNA29a detection achieved the highest Youden index (0.733), sensitivity (92.6%), positive predictive value (46.2%), negative predictive value (98.3%) and higher specificity (80.7%) when identifying missed high-grade lesions. CONCLUSIONS: Detection of miRNA might provide a new triage for identifying a group at higher risk of missed high-grade lesions in women with colposcopy diagnosis of LSIL/CIN1.
