Portugal is the Western European country with the highest incidence rate of cervical cancer, being the Human Papillomavirus (HPV) infection its main cause. Cervical cytology is the most widely used screening method for the prevention and detection of cervical cancer, either by conventional means or by liquid basis. Conventional cytological preparations have more limitations than liquid-based preparations, however, when dealing with glandular lesions, both conventional and liquid-based cytology have some drawbacks. We report the case of a 31-year-old woman whose results from the screening cytology tests diverge from histological diagnosis. With this study we intend to highlight the limitations of conventional cytology in relation to the liquid-based cytology in the diagnostic of glandular lesions.

Abstract Background: High-risk human papillomavirus (HR-HPV) infection is widely known as the major cause of cervical intraepithelial neoplasia (CIN) and cervical cancer and it’s characteristics vary greatly in different population. Women with abnormal cervical cytology could increase the risk of cervical cancer, however, HR-HPV infection characteristics in women with abnormal cervical cytology remains unclear. Methods: This study was based on baseline survey of the CIN Cohort established in Shanxi Province, China. A total number of 2300 women with cervical abnormalities were enrolled in this study. All participants gave informed consent and agreed to HPV and thinprepcytologic test (TCT). Each individual completed a questionnaire about characteristics related to HPV infection. Results: The overall prevalence of HR-HPV in 2300 women was 32.0%, and the proportion of single and multiple HR-HPV infections were 70.2% and 29.8% in HR-HPV infection women, respectively. The top five HR-HPV genotypes were ranked as HPV16, HPV58, HPV52, HPV53 and HPV51. The prevalence of HR-HPV in atypical squamous cells of undetermined significance (ASC-US), low-grade squamous intraepithelial lesion (LSIL) and high-grade squamous intraepithelial lesion and above(HSIL+) were 30.8%, 36.5% and 54.9%, respectively, showing an increasing trend with the severity of cervical cytology ( χ 2 trend =13.952; p <0.001). The women aged 35~45 years, with lower education level, less frequency of bathing, multiple gravidity, multiple parity, history of gynecological diseases and premenopausal women were prone to HR-HPV infection. Conclusions: We defined the characteristics related to HR-HPV infection in abnormal cervical cytology women, and provided an insight for the development and deeply research of HPV vaccine.

The Difference

ABSTRACT Aim To evaluate and compare the efficacy of liquid-based cytology (LBC) with conventional cytology (CS) as a screening tool for cervical cancer in postmenopausal women. Materials and methods This was an observational crosssectional study conducted over one year. Subjects were recruited from patients attending the outpatient department of the Department of Obstetrics and Gynecology, King George's Medical University, Lucknow, Uttar Pradesh, India. Pap smear and LBC were taken in all subjects. In cases with suspected lesions, the discrepancy between Pap smear and LBC and colposcopy was found. Results Pap smear reported 14.3% inadequate smears in women with postmenopausal changes and 5% inadequate smears in women without postmenopausal changes. In contrast, LBC reported no inadequate smear. This difference was statistically significant (p = 0.011). Cervical neoplasia was ruled out in 53.6% cases by Pap smear and 75.8% cases by LBC. The difference was statistically significant (p = 0.002). Conclusion Liquid-based cytology offers better results in detecting cervical pathology when compared with Pap smear. Liquid-based cytology could be better as a screening method, especially in postmenopausal women in which the screening is challenging due to menopause-induced anatomical and hormonal changes. Clinical significance Cervical cancer is the most common genital cancer among Indian women. Postmenopausal women are at higher risk for developing cervical cancer. Low estrogenic state poses a challenge for detection of cervical cancer by CS in postmenopausal women. We investigated LBC as a better cervical cancer screening tool in this age group.

ObjectivesThe objective of this study was to evaluate the frequency of human papillomavirus (HPV) in the oral cavity of women with and without abnormal cervical cytology and to determine whether there is an association of oral HPV infection with infection of the cervix or with cervical cancer precursor lesions.MethodsThe present study was conducted among 406 women, aged 18–82 years, who attended the Prevention Department of Barretos Cancer Hospital (HCB), Brazil due to a previous altered cervical cytology result. Oral rinse, cervical cytology and biopsy were collected at the same day. The participants also answered a questionnaire about socioeconomic characteristics and risk factors for cervical cancer. Molecular screening for HPV16, HPV18 and 12 other high-risk HPV types was performed on cervical and oral rinse specimens using Cobas 4800 (Roche Molecular Systems, USA).ResultsHPV was detected in the oral rinse of 3.9% of participants. Infection of the oral cavity with a non-HPV16 or 18 type was most frequent (81.2%), followed by HPV16 (18.7%). Infection with HPV in the cervix and oral cavity was present in 11 (2.7%) of participants. There were no differences observed in the smoking status (p value 0.62), mean age of first sexual intercourse (p value 0.25), mean age of the first oral sex (p value 0.90) or mean lifetime number of sexual partners (p value 0.08) between the participants with oral HPV infection or not.ConclusionThe presence of HPV infection in the oral cavity was low in the group of women with abnormal cervical cancer screening findings and a high rate of cervical HPV infection.

There are more supports for the view that human papillomavirus (HPV) infection might be an etiological factor in the development of cervical cancer when the association of persistent condylomata is considered. Biopsies from 318 cases with squamous cell carcinoma of uterine cervix, 48 with cervical and vulvar condylomata, 14 with cervical intraepithelial neoplasia (CIN), 34 with chronic cervicitis and 24 normal cervical epithelium were collected from 5 geographic regions of China with different cervical cancer mortalities. All specimens were prepared for Dot blot, Southern blot and in situ DNA-DNA hybridizations by using HPV-11, 16, 18 DNA labelled with 32P and 3H as probes to detect viral homologous sequences in samples. Among them, 32 cases with cervical cancer, 27 with condyloma and 10 normal cervical epitheliums were randomly chosen for comparative EM observation. The results showed that: 1), 192 out of 318 (60.4%) cases of cervical cancer were positive for HPV-16 DNA probe (Table I)

High-risk human papillomavirus strains are widely known to be the causative agents responsible for cervical cancer development. Aggregated damage caused by papillomaviruses solely is estimated in at least 5% of all malignancies of the human body and 16% in cancers that affect the female genital area. Enhanced understanding of the complex issue on how the high extent of carcinogenicity is eventually formed due to the infection by the Papoviridae family would contribute to enhancing current prevention strategies not only towards cervical cancer, but also other HPV associated cancers. This review article is aimed at presenting the key points in two directions: the current cervical cancer prevention and related aspects of HPV behavior. Virtually all applied technologies related to HPV diagnostics and screening programs, such as HPV tests, colposcopy-based tests (VIA/VILI), conventional and liquid-based cytology, currently available are presented. Issues of availability, advantages, and drawbacks of the screening programs, as well as vaccination strategies, are also reviewed in the article based on the analyzed sources. The current point of view regarding HPV is discussed with emphasis on the most problematic aspect of the HPV family concerning the observed increasing number of highly carcinogenic types. Present trends in HPV infection diagnostics throughout the human fluids and tissues are also reported, including the latest novelties in this field, such as HPV assay/self-sample device combinations. Besides, a brief outline of the related prevention issues in Kazakhstan, the leading country of Central Asia, is presented. Kazakhstan, as one of the post-soviet middle-income countries, may serve as an example of the current situation in those terrains, concerning the implementation of globally accepted cervical cancer prevention strategies. Along with positive achievements, such as the development of a nationwide screening program, a range of drawbacks is also analyzed and discussed.

ObjectiveHuman papillomavirus (HPV) infection causes multiple cancers in both women and men. In China, both HPV vaccination and cervical cancer screening coverages are low. We aim to investigate the temporal and geographical trends of HPV DNA prevalence in heterosexual men, women, men who have sex with men (MSM) and people living with HIV (PLHIV) in China.MethodsWe conducted a systematic review, collecting publications in PubMed, Web of Science, China National Knowledge Infrastructure (CNKI) and Wanfang Data from January 2000 to May 2017. A total of 247 studies were selected for this meta-analysis to estimate pooled HPV prevalence, incidence of cervical cancer and risk of infection for subgroups. Meta-regression was applied to identify contributing factors to prevalence heterogeneities.ResultsThe national HPV prevalence was 15.6% (95% CI (14.4% to 16.9%)) in women with normal cervical cytology, and Central China had the highest prevalence (20.5% (15.2% to 25.8%)). HPV prevalence in heterosexual men (14.5% (11.3% to 17.7%)) was comparable with that of women (OR=1.09 (0.98 to 1.17)), but HPV prevalence in MSM (59.9% (52.2% to 67.6%)) was significantly higher than that in heterosexual men (OR=8.81 (8.01 to 9.69)). HIV-positive women (45.0% (38.4% to 51.6%)) and HIV-positive MSM (87.5% (82.3% to 90.9%)) had 4.67 (3.61 to 6.03) and 6.46 (5.20 to 8.02) times higher risk of HPV infection than their HIV negative counterparts.ConclusionHPV infection is prevalent in China, particularly in Central China, in comparison with the global level and neighbouring countries. Targeted HPV vaccination for women, MSM and PLHIV and scale-up of cervical screening for women are priorities in curbing the HPV epidemic in China.

Abstract Background: Human papillomavirus (HPV) infection is the main cause of precancerous lesions and cervical cancer in women. To determine the epidemiological characteristics as well as the relationship between the HPV genotype and cytology test results among women, we retrospectively collected and analyzed the data from Zhoupu District hospital in Shanghai, China.Methods: We made a retrospective analysis of human papillomavirus prevalence rate of 23,724 women between 2014 and 2019 in the District Zhoupu of Shanghai City in China. Their cervical exfoliations were collected. HPV genotype testing was performed using a commercial kit designed to detect 21 HPV subtypes including 15 high-risk HPV subtypes(16, 18, 31, 33, 35, 39, 45, 51, 52, 53, 56, 58, 59, 66 ,68) and 6 low-risk HPV subtypes(6, 11, 42, 43, 44 and 81). And the thinPrep cytological test (TCT) was also performed at the same time.Results: Among all 23,724 cases, 3,816 (16.08%) women were infected with HPV. HPV52 (3.19%), HPV58 (2.47%) and HPV16 (2.34%) had higher prevalence. 3,480(91.20%) single-type infections were more common than 336(8.8%) multiple-type infections. Single-type infection was more frequently seen in women aged 50–60 years (16.63%) and <30 years (15.37%), and multiple-type infection was more common in those aged >= 60 (2.67%). Significant differences in secular trends from 2014 to 2019 were observed for subtypes HPV52, 58 and 16.HPV positive rates of women changed significantly along with the time period from 2014 to 2019.Among 4,502 TCT positive women, 15 (4.04%), 125 (2.64%) ,159 (1.54%), 4,202(17.71%) and 1(0.004%) had atypical squamous cells (ASC), high-grade squamous intraepithelial lesions (HSIL), low-grade squamous intraepithelial lesions (LSIL), atypical glandular cells (AGC) and cervical adenocarcinoma respectively. The HPV infection rates were 66.08%, 63.99%, 115.20%, 119.50%, and 31.72% for NILM, AGCs, HSILs LSILs and ASCs, respectively.Conclusions: HPV and TCT screening were a key step in the secondary prevention of cervical cancer. Further tracking the results of HPV and TCT was an important clinical strategy for the treatment of cervical precancerous lesions. The widespread use of preventive HPV vaccines can significantly reduce the incidence of pre-neoplastic and neoplastic cervical lesions.
