Abstract Background: High-risk HPV(hr-HPV) infection is important for the development of invasive cervical cancer. As a developing country with the largest population in the world, China has a great burden of cervical cancer. The cervical cancer screening strategies consisted of cytology and virology, which has been studied by HPV-typing test and HPV-DNA quantitative test since decades ago. The cervical cancer incidence rate has been declined due to the early treatment of precancerous lesions, but postoperative HPV infection is still an issue for cervical cancer patients. This study aims to investigate the association between HPV infection status and recurrence of early-stage cervical cancer through a novel PCR-based HPV test, which could do both HPV typing-test and DNA quantitative-test. Methods: Patients diagnosed with cervical cancer staged IB1- IIA2, who were treated by radical hysterectomy and lymphadenectomy at Cancer Hospital Chinese Academy of Medical Sciences(CAMS) between January 2014 and December 2016 were accrued. The clinicopathological factors, pre- and post-operative HPV infection status, and the prognosis were investigated. Cox regression was used to identify factors associated with LRFS, MFS and OS. Results: A total of 312 patients were enrolled in this study, who were treated by radical resection and accepted pre- and post-operative HPV tests, with a median follow-up time of 60 months(range 14~79 months). The 5-year LRFS rate, MFS rate, and OS rate were 97.8%, 98.4%, and 98.7%. The pre-operative HPV infection rate was 85.3%(266/312), 74 patients had a high level of HPV-DNA(>5x106 copy number/104 cells). Twenty-nine patients had a postoperative persistent high level of HPV-DNA(9.3%). Postoperative persistent high level of HPV-DNA within 12 months(p=0.013), postoperative persistence of HPV-16/18 within 24 months(p=0.004), and deep stromal invasion(>2/3)(p=0.007) were associated with a poor LRFS.Conclusion: Pre-operative HPV-16/18 infection and high level of HPV-DNA were not associated with local recurrence of cervical cancer. Most initial HPV-positive patients had HPV cleared within 24 months postoperatively. Postoperative HPV-16/18 persistence within 24 months, postoperative persistence of high HPV-DNA level within 24 months, and deep stromal invasion(>2/3) were independent risk factors for local recurrence of cervical cancer.

Background: Cervical cancer is one of the most common types of cancer affecting women worldwide. Persistent HPV infection plays a major role in cervical cancer. The risk of cervical cancer has increased in parallel with the incidence of certain genotypes of human papilloma virus (HPV). Methods: The study was aimed to detect the distribution of HPV genotypes among cervical cancer patients from a specialized hospital in Dhaka, Bangladesh. HPV DNA testing was done by polymerase chain reaction (PCR) using SPF-10 broad-spectrum primers followed by genotyping by reverse hybridization using the INNO-LIPA genotyping system at the Department of Virology, Bangabandhu Sheikh Mujib Medical University, Dhaka. Results: HPV 16 was more prevalent (72.0%) in cervical cancer patients from Bangladesh followed by type 18 (6.0%) and 45 (2.0%). Genotype 16 and 18 alone and as co-infection were detected in 88.0% cases. Multiple HPV infection was found in 20% patients. Along with high risk (HR) HPV 16, 18 and 45 HR HPV 56, 39, 31 and 58 were also prevalent in multiple infections. Conclusion: Thus the study concluded that HR HPV 16 and HPV 18 were more prevalent genotypes among cervical cancer patients in a specialised hospital in Bangladesh. Along with HR HPV 16 and HPV 18, HR HPV 45, 56, 39, 31 and 58 were also prevalent Bangladesh Med Res Counc Bull 2019; 45: 86-92

Abstract Background and aim This cross-sectional study investigated the prevalence and risk factors of high-risk human papilloma virus (HPV) infection, especially types 16 and 18, and cervical neoplasia in female Inflammatory bowel disease (IBD) patients. Methods From July 2014 to January 2017, sexually active, female, Chinese IBD patients (21–60 years) and age-matched controls underwent cervical ThinPrep cytology testing (TCT) and high-risk HPV-DNA detection, and completed questionnaires about awareness of cervical cancer and HPV. Cervical dysplasia was categorized as cervical intraepithelial neoplasia (CIN) 1, 2 and 3. Results Of 124 IBD patients (30 ulcerative colitis and 94 Crohn’s disease), 17 (13.7%) had high-risk HPV among whom 9 (7.3%) had HPV 16/18 infection and 4 (3.2%) had cervical CIN (3 CIN 3, 1 CIN 1) by pathology. Among 372 controls, 33 (8.9%) had high-risk HPV and only 1 (0.3%) had HPV 16 infection. Cervical TCT detected atypical squamous cells of unknown significance in one control; no control had CIN. The HPV 16/18 infection rate and CIN prevalence were significantly higher in IBD patients than controls (both P < 0.001). The HPV-infection rate was higher in patients administered methotrexate [P = 0.005, odds ratio (95% confidence interval) 4.76 (1.471–15.402)] or more than two immunosuppressants [P = 0.013, odds ratio (95% confidence interval) 3.64 (1.255–10.562)]. Thiopurine, steroid, infliximab and disease behavior/location were not associated with HPV infection. Only 29.3% of patients had undergone cervical-cancer screening. Awareness of HPV infection and HPV-related cervical cancer was poor (28.2%). Conclusions Female IBD patients are at increased risk of high-risk HPV infection and cervical neoplasia, which may be associated with immunosuppressants. Education and routine follow-up with HPV-DNA testing and TCT are recommended, especially in female Chinese IBD patients.

ABSTRACT: Introduction: Human papillomavirus (HPV) is considered a necessary causative agent for developing oropharyngeal, anal and cervical cancer. Among women in Ecuadorian population, cervical cancer ranks as the second most common gynecological cancer. Not many studies about HPV burden have been published in Ecuador, and genotypes distribution has not been established yet. The little data available suggest the presence of other genotypes different than 16 and 18. Objectives: In the present study, we attempt to estimate the prevalence of HPV 16, HPV 18 and other 35 genotypes among Ecuadorian women undergoing cervical cancer screening. The overall prevalence of HPV infection was also estimated. Methods: Routine cervical samples were analyzed using Linear Array(r) HPV Genotyping test (Roche). Results: A total of 1,581 cervical samples obtained from Ecuadorian women undergoing cervical cancer screening were included in this study. HPV DNA was detected in 689 cervical samples (43.58%). Of these samples, 604 (38.20%) were positive for a single HPV genotype, while another 85 (5.37%) samples were positive for multiple HPV types. Genotype 16 (5.50%) resulted in the most frequently detected type in both single and multiple infections. HPV 33 (4.55%) and HPV 11 (3.80%) occupied the second and the third place in frequency among all detected genotypes. Conclusions: Viral genotypes different from HPV 16 and HPV 18 are frequently detected among Ecuadorian women. The overall prevalence of HPV resulted higher than the one reported in other South American countries with a greater burden in the second and third decades of life.

This article is a preliminary investigational study that is aimed at giving hints about the interesting biomarkers involved in the transition process from low-grade cervix lesion to invasive cervical cancer. Our study focuses on the risk factors and tumour molecular changes in one patient. First in 1986, she was diagnosed a preinvasive cervix lesion. Then, 16 years later, she was diagnosed an invasive cervical cancer. The 2002 diagnosis was a squamous cell carcinoma of the cervix, stage IIIB (FIGO), whereas in 1986, she had been diagnosed a high-grade squamous intraepithelial cervical lesion. Retrospectively, the analysis of samples of preneoplastic lesions and invasive cervical cancer confirmed the histopathological diagnoses and detected the presence of HPV type and HPV-16 variants, as well as the overexpression of proteins such as hTERT, IGF1Rα, IGF1Rβ, CAIX, and GLUT1. Finally, the Arg72Pro polymorphism was detected in TP53. The role of high-risk HPV and HPV-16 variants and of hTERT, IGF1Rα, IGF1Rβ, CAIX, and GLUT1 variations seemed confirmed in the development and progression of cervical cancer. As a result, analyzing the molecular changes in one and same tumour that progresses from a low-grade cervix lesion to invasive cervical cancer could provide valuable information in order to improve detection, diagnosis, and treatment in the future.

Objective Human papillomavirus (HPV) has been identified as the principal etiologic agent for cervical cancer and its precursors. Different HPV types have been associated with different oncogenic potential. The purpose of this study was to evaluate the relationship between specific HPV type infection and expression pattern of the ras family oncogenes in different grades of HPV-associated human cervical neoplasia. Methods HPV typing was performed using polymerase chain reaction (PCR) in 31 HPV-positive human cervical specimens from patients with squamous intraepithelial lesions (SIL) or squamous cervical carcinoma (SCC). The mRNA expression levels of H-, K- and N-ras oncogenes were examined using the reverse transcriptase polymerase chain reaction (RT-PCR) technique. Statistical analyses were performed using SPSS software. Results Among patients with SCC, H-, K- and N-ras expression levels were higher in HPV 16/18-associated cases compared to HPV 16/18-unassociated samples (p=0.003, p=0.004 and p=0.0001, respectively). The expression levels for H-, K-and N-ras were significantly higher in SCC patients with multiple HPV infection compared with SCC patients with single HPV infection (p=0.009, p=0.01 and p=0.021, respectively). Among patients with SIL, no statistically significant relationship was found between ras expression and HPV status. Conclusion Our findings indicate the possible role of ras signaling interaction with “high-risk” HPV 16/18 and multiple HPV infection in cervical cancer development.

AbstractCervical cancer morbidity and mortality in Lithuania is one of the biggest in the European Union. The main risk factor of cervical cancer is human papillomavirus (HPV). The deletion of the HPV E2 gene influences HPV DNA integration into the cell genome, as well as a rapid progression of cervical lesions. The purpose of this study is to determine HPV, its types, and HPV 16 integration in different grades of cervical intraepithelial neoplasias (CIN). 253 women with cytological lesions were involved in the study. After a histology, 31 women were diagnosed with CIN I, 35 with CIN II, and 51 with CIN III. The biggest prevalence of HPV infection was detected in women younger than 25 years old (69.7%) and in women with CIN II (90.9%). HPV 16 was detected in 67.8% of all cases, with the highest prevalence in CIN III (84.4%). A partial integration form was detected in 65.0% of HPV 16 infected women, a complete virus integration in 26.5%, and an episomal form in 8.4% of cases. Our study concludes that in all the cases confirmed using a histology, the partial virus integration form of CIN was identified the most. It was less frequently detected in CIN I cases (60.0%), but more frequently in CIN II and CIN III cases (72.8 and 69.3%, respectively).

Human papilloma virus is an oncogenic DNA virus, which is identified in 99.7% case of invasive cancer. It is the most prevalent virus involved in sexually transmitted diseases worldwide and an important public health challenge for the prevention of cervical carcinoma. Cervical cancer is the second cause of malignant neoplasia and death in women. The present study was thus designed to detect the risk factors for HPV infection in normal and unhealthy cervix of women attending tertiary care hospital (BSMMU). HPV DNA was detected among the study population using the Hybrid Capture 2 assay, which determined HPV high risk types. A total of 68 women between 25-70 years of age were included in this cross sectional study. Among them 13 (19.1%) cases were tested positive for HPV DNA. The risk factors for HPV infection identified from this result are early sexual activity, lower level of education, early marriage, multi-parity, total duration of sexual activity in years and long term use of oral contraceptive pill and poor socioeconomic condition. Increased awareness and understanding regarding HPV infection would improve the risk of infection and control in sexually active women. HPV diagnosis at early stages of infection is of fundamental importance. The use of HPV test in routine cervical mass screening may not be possible in developing countries like Bangladesh due to its high cost. Nevertheless, it has been shown to be a useful tool when combined with cytology to diagnose high-risk infection in apparently normal tissues, and may help to reduce the risk of cervical cancers. The results obtained from this study ultimately contribute to cervical cancer prevention among Bangladeshi women. DOI: http://dx.doi.org/10.3329/bmjk.v46i1-2.18231 Bang Med J (Khulna) 2013; 46 : 3-6

AbstractIntroduction. The most common risk factor for intraepithelial lesions and cervical carcinoma is infection with human papillomavirus (HPV), especially with high-risk HPV genotypes. Only persistent, high-risk HPV infections represent a major risk factor for intraepithelial lesions and cervical cancer. The aims of the study were: detection and typisation of HPV genotypes, which are the most common causes of intraepithelial lesions and cervical cancer, determination of the correlation between HPV infection and histopathological diagnosis, and the correlation between the grade of lesion of the cervix and oncogenic potential of the virus as well as determination of the most affected age group of patients.Methods. This cross-sectional study included 100 sexually active patients with an abnormal Pap test at the age from 20 to 69 years (39±10.77), and was conducted at the University Clinic of Gynecology and Obstetrics in Skopje and University Clinic of Radiotherapy and Oncology in Skopje in the period from January 2014 to August 2014. In all patients colposcopic cervical biopsy was made with endocervical curettage for histopathological analysis and cervical biopsy for detection and HPV typisation. HPV detection and typisation were done using polymerase chain reaction (PCR) and reverse hybridization.Results. HPV DNA was detected in 81.0% (81/100) of the examined women. The relationship between the prevalence of high-risk and low-risk HPV DNA genotypes was 72.0%:9.0%. The frequency of high-risk HPV DNA genotypes ranged from: 54.5% (12/22) in productive HPV infection-mild dysplasia, 86.4% (19/22) with moderate dysplasia, 91.2% (21/23) in severe dysplasia to 100% of squamous cell carcinoma in situ (6/6) and invasive squamous cell carcinoma (5/5). Mixed HPV infection was detected in 19.0% (19/100) of all patients, in 23.5% (19/81) of HPV DNA positive patients. The most common HPV DNA genotypes, in descending order, were HPV 16 (43.2%), HPV 31 (28.4%), HPV 18 (14.8%), etc. The highest frequency of HPV infection was found in patients under 30 years of age.Conclusion. There was an association between HPV infection and squamous intraepithelial lesions and squamous invasive carcinoma of the cervix. There was a correlation between the grade of cervical lesion and the oncogenic potential of the virus. The results of this study may be useful for building a national strategy in the fight against cervical cancer.

The purpose of the study was to assess detection rates of human papillomavirus in cervical cancer cases of Nizhny Novgorod. Materials and methods. We used the real-time polymerase chain reaction (PCR) to test samples of mucosa lining of the cervical canal and/or transformation zone taken from 630 women with cervical dysplasia of different degrees and 107 incident cases of cervical cancer that did not undergo treatment. The detection and differentiation of 14 genotypes of high-risk human papillomaviruses (HPV) was carried out using the AmpliSens® HPV HCR-genotype-FRT PRC kit. Results. The overall infection rate of women with oncogenic human papillomaviruses was 41.8%. Among the genotypes, HPV 16 (39.2%), 18 (15.5%), 33 (16.6%), and 56 (11.9%) predominated. A high prevalence of oncogenic HPV was detected in the women with cervical intraepithelial neoplasia (58.1%) and cervical cancer (90%). The spectrum of genotypes in women with neoplasia of various degrees differed. In women with CIN II and CIN III, vaccine-preventable HPV genotypes (HPV 16 and 18) playing the leading role in the development of cervical cancer were the most frequent. The same genotypes dominated in the women with invasive cervical cancer. One oncogenic HPV genotype was usually found in the infected women (69%). The high-risk HPV infection was often combined with Ureaplasma ssp (49.3%), Mycoplasma hominis (20.1%), Cytomegalovirus (21.1%), and Herpes simplex I/II (18.2%) infections. Combinations of high-risk HPV with Chlamydia trachomatis and Herpes 6 were found in 8.3% and 5% of the cases, respectively. Conclusions. Our findings proved a wide prevalence of high carcinogenic risk HPV 16 and 18 genotypes, thus indicating the expediency of using Cervarix and Gardasil vaccines registered in the Russian Federation and containing antigens to these types of virus for specific prevention of the HPV infection.

Objective: Our objective was to verify the sensitivity and specificity of dual immunocytochemistry staining for p16 and Ki-67 in liquid-based samples (the “dual” assay) for cervical lesion screening, compared to biopsy findings and human papillomavirus (HPV) DNA molecular detection. Study Design: Sensitivity, specificity, and positive (PPV) and negative (NPV) predictive values for the “dual immunocytochemistry assay” were calculated and compared to histopathological results and to high-risk HPV DNA detection in adult women or teenagers submitted to cervical cancer screening. Results: A total of 151 women were included. The majority (96.2%) of those with negative dual assay results had lower biopsy grades (p < 0.001). Women with cytology results suggestive of cervical cancer had positive dual immunocytochemistry assay results more frequently (p < 0.001), and these positive results were also significantly associated with biopsy findings (p < 0.001) and with high-risk genotype HPV infection (p = 0.007). Specificity and PPV for the dual assay were 0.972 (0.855–0.999) and 0.800 (0.284–0.995), respectively, and 1.000 (0.590–1.000) and 1.000 (0.631–1.000) for HPV detection. Conclusions: The dual immunocytochemistry assay had high specificity and PPV. It reveals a persistent HPV infection, avoiding the need for new tissue collections for biopsies or hybrid capture.
