Dai W, Wang T, Chen L, Qiu Z, Chen P, Chen D. Immediate risk of cervical intraepithelial neoplasia and diagnostic value of colposcopy among cytology-negative women with oncogenic HPV: a retrospective study. BMC Womens Health 2024; 24:419. [PMID: 39049047 PMCID: PMC11267838 DOI: 10.1186/s12905-024-03258-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2024] [Accepted: 07/10/2024] [Indexed: 07/27/2024] Open
Abstract
BACKGROUND Cervical cancer screening results that are negative for cytology but positive for high-risk human papillomavirus (HR-HPV) are not uncommon. One-year follow-up is suggested for patients with no history of HPV positivity under the most recent American Society of Colposcopy and Cervical Pathology (ASCCP) guidelines (2019). The aim of this study was to evaluate the immediate risk of cervical intraepithelial neoplasia (CIN) among cytology-negative patients positive for HR-HPV. The diagnostic accuracy of colposcopy in these patients was investigated. METHODS A retrospective study was conducted in patients who were cytology negative but HR-HPV positive and referred for colposcopy from January 2022 to August 2023. Patients were compared in terms of the immediate rate of CIN lesions among the HPV16-positive group, the HPV18-positive group and the non-16/18 HR-HPV-positive group. The distribution of CIN2 + lesions according to age was evaluated. The factors associated with the accuracy of colposcopy were evaluated using univariate and multivariate logistic regression. RESULTS Among the 372 patients, 195 had chronic cervicitis, 131 had CIN1, 37 had CIN2/3, and nine had carcinoma. The immediate rates of CIN2 + lesions and CIN3 + lesions in patients who were not HR-HPV16/18-positive were comparable to those in patients who were HPV16/18-positive (P = 0.699). In addition, among patients diagnosed with CIN2 + lesions, 8 (17.39%) patients were women aged < 30 years. When pathological results were used as a reference, the consistency rate of colposcopy was 61.0% (227/372). Multivariate analyses revealed that age and the type of cervical transformation zone were independent factors affecting the accuracy of colposcopy (P < 0.001). CONCLUSIONS In countries with limited resources, immediate colposcopy referral should be recommended for patients who are cytology negative but HR-HPV-positive (including non-16/18 HR-HPV-positive), and cervical cancer screening via cotesting should be suggested for women aged < 30 years. Colposcopy has moderate diagnostic value and can be affected by age and the type of cervical transformation zone.

Abstract
Introduction Cervical cancer (CC) is the fourth most prevalent female cancer globally. Understanding its epidemiology is crucial for devising practical strategies suited to geographic and social contexts to attain the global eradication of CC. Hence, this study examined the latest evidence of risk factors contributing to CC development. Methods An independent literature search was conducted on PubMed using MESH terms. The primary sources were meta-analyses published from 2010 to 2023, which detail updated evidence on risk factors associated with CC. Additionally, the quality of the evidence was evaluated using the GRADE system and recommendations were made accordingly. Results The main risk factors related to the cause of CC include co-infections with other sexually transmitted infections, genetic markers, cervicovaginal microbiota, nutritional factors, comorbidities that affect the immune response, smoking, and the use of hormonal contraceptives with a quality evidence based on the GRADE scale moderate. Conclusions Since the necessary cause for CC is persistent cervicovaginal HPV, all the risk factors implicated in the causality of CC act as non-independent cofactors that increase the risk of CC. Thus, changes in public policies aimed at addressing these risk factors are highly recommended and can substantially decrease the risk of CC.

Abstract
BACKGROUND Women living with HIV are at risk for cervical dysplasia and cancer worldwide. In 2015, the World Health Organization (WHO) recommended that testing for high-risk HPV (hrHPV) infection be incorporated into cervical cancer screening programs using molecular nucleic acid tests (NATs) but this has not previously been done in Uganda. The country's coverage for Human Papilloma Virus (HPV) screening remains low at less than 10% for women aged 25-49 years. This study determined the genital prevalence of hrHPV infection and the associated factors among women living with HIV in Uganda. METHODS A descriptive cross-sectional study was conducted in 15 selected health facilities among participants who were on Antiretroviral therapy (ART). Participants who consented to participate were instructed on how to collect their own high vaginal swabs using a cervical brush for HPV molecular testing (HPV DNA or HPV RNA) and their demographics data was collected using a standard questionnaire. Laboratory diagnosis for HPV molecular testing was done using Gene xpert machines and Hologic Aptima Machine. Modified Poisson regression analysis was conducted to determine the associated factors. RESULTS This study involved 5856 HIV positive participants on ART. A total of 2006 out of 5856 (34.3%) participants had high risk HPV infections. HPV infections by genotypes were: HPV16 317(15.8%), HPV 18/45 308 (15.4%) and other high-risk HPV 1381 (68.8%). The independent factors associated with all hrHPV were parity, education level, having more than one partner, and engaging in early sex. Smoking was associated with HPV 16, HPV 18/45 and other hrHPV. Age was associated with all hrHPV, marital status with HPV 16, and occupation with HPV 16. CONCLUSIONS The prevalence of genital high-risk HPV infections among HIV positive women attending ART clinics in public facilities in Uganda was high. Other hrHPV genotype was the commonest compared to 18/45 and HPV 16. The integration of cervical cancer screening in ART programmes remains paramount to support the early detection of cervical cancer and Non-invasive self-collected urine and vaginal sampling for cervical cancer screening present an opportunity.

Abstract
Cervical lesions, induced by high-risk oncogenic human papillomavirus (HR-HPV), in the context of HIV remains a global health challenge. We determined the effect of HR-HPV on the development of cervical lesions in women with and without HIV infection. A cross-sectional analytical study was conducted among 257 women living in Cameroon. HIV serology, HR-HPV genotyping and cervico-vaginal smear (CVS) were performed for all participants; among those declared HIV positive, plasma HIV viral load and CD4 count were measured. Statistical analyses were performed using Graph Pad version 6.0; P#x003C;0.05 was considered statistically significant. The mean age of the participants in our study was 37±6.5 years. According to HIV serology, 184 (71.59%) were HIV-positive vs. 73 (28.40%) HIV-negative. Among the HIV-positive women, the median CD4 count was 438 [IQR: 317-597] cells/mm3 and the median viremia was #x003C;40 [IQR: #x003C;40-2318] copies/ml. After successful genotyping, the prevalence of HR-HPV was 36.32% (73/201), with a significantly higher proportion in HIV-infected individuals (41.98% (55/131) vs. 25.71% (18/70); P=0.02; OR=2.1). The overall rate of cervical lesions was 23.34% (60/257), with a non-significantly higher proportion in HIV-infected participants (25.00% (46/184) vs. 19.17% (14/73); P=0.31). Relevantly, the presence of HR-HPV was significantly associated with cervical lesions (P#x003C;0.0001; OR=5.07), with a higher odds of cervical lesion in HIV-positive individuals (P#x003C;0.0001 and OR=5.67) compared to HIV-negative individuals (P=0.03 and OR=3.83). Although oncogenic HPV appears to be an independent factor in the development of cervical lesions, this study reveals higher odds of cervical lesions among HIV/HPV co-infection than in HPV infection alone.

Abstract
OBJECTIVE The aim of this study was to explore the prevalence of low and high-risk HPV genotypes in PAP smear samples of women in northern region of the UAE using HPV direct flow CHIP method. METHODS A cross-sectional retrospective study was conducted between September 2021 to April 2022. A total of 104 liquid-based cervical cytology samples were obtained from women aged 20-59 years attending the Gynaecology out-patient department of Thumbay University Hospital and other hospitals of Northern Emirates of UAE, processed for the routine cytological examination to identify and differentiate morphological changes of the PAP smear samples. HPV genotyping was performed using HPV direct flow CHIP method. RESULTS In total, 112 HPV genotypes were detected in 63 women (60.57%) included 18 abnormal cytological and 45 normal epithelial samples. 63 LR and 49 HR HPV genotypes were identified in all the 63 positive samples. Highest rate of infection with multiple LR and HR HPV genotypes were detected in women aged 40-49 years (25.9%) and 20-29 years (23.5%). Infection by HPV6 (13.46%), HPV11 (9.61%), HPV16 (9.61%), HPV62/81 (7.69%) and HPV45 (7.69%) were the most common genotypes. A moderate increase than expected incidence of HPV45 and 62/81 (7.69%) were detected. Co-infection with multiple low and high-risk genotypes is present in 20.2% cases; in that, HPV6 (15.9%) was the most common followed by HPV62/81 (12.7%) and HPV16 (11.11%). The prevalence of HPV18 was found to be 1.6%. CONCLUSION The genotypes 6, 45, 16, 11, 67, 62/81 were the most common HPV infections in the women between the age group of 21 and 59-years-old. A moderate increase of HPV45, 62/81 and much less prevalence of HPV18 were detected in the study population. 43.27% of the normal epithelia were positive to different low and high-risk HPV genotypes. This finding highlights the importance of molecular genotyping of HPV to emphasize the cervical screening triage.

Biological, demographic, and health factors associated with HPV infection in Ecuadorian women. Front Public Health 2023; 11:1158270. [PMID: 37397749 PMCID: PMC10311495 DOI: 10.3389/fpubh.2023.1158270] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2023] [Accepted: 05/11/2023] [Indexed: 07/04/2023] Open
Abstract
Objectives The study aims to identify the correlation between human papillomavirus (HPV) infection and sociodemographic and sexual reproductive health factors in Ecuadorian women from March to August 2019. Methods 120 women were randomly selected from two gynecological clinics to complete a questionnaire and provide a biospecimen. PCR-Hybridization was used to genotype 37 HPV serotypes in samples obtained by endo-cervical brushing for liquid-based cytology. Sociodemographic and sexual health data were collected through a validated questionnaire during a medical consultation. Mathematical modeling of HPV infection was done using bivariate logistic regression. Results 65.0% of the women sampled had an HPV infection; 74.3% of these women had co-infections with other HPV genotypes. Out of the women who were HPV positive, 75.6% were diagnosed with high-risk genotypes from HPV strains 18, 35, 52, and 66. Parity, immunosuppression, and use of oral contraception/intrauterine devices (IUDs) were identified as associated variables. The explanatory model had a sensitivity of 89.5% and a specificity of 73.8%. Conclusion The predominant strains of HPV among Ecuadorian women are diverse. The risk of HPV infection is a complex phenomenon where biological and psychosocial variables are integrated into a model. In populations with limited access to health services, low socioeconomic status, and negative sociocultural beliefs about sexually transmitted infections (STIs), surveys can be used as a pre-screening step for HPV infections. The diagnostic value of the model should be tested in multicenter studies that include women from all over the country.

Correlation analysis of vaginal microecology and different types of human papillomavirus infection: a study conducted at a hospital in northwest China. Front Med (Lausanne) 2023; 10:1138507. [PMID: 37324149 PMCID: PMC10267365 DOI: 10.3389/fmed.2023.1138507] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2023] [Accepted: 05/08/2023] [Indexed: 06/17/2023] Open
Abstract
Background Vaginal microecology has a definite influence on human papillomavirus (HPV) infection and clearance, but the specific correlation is still controversial. This research aimed to investigate the differences in the vaginal microenvironment of different types of HPV infection and also provide data supporting clinical diagnosis and treatment. Methods According to strict inclusion and exclusion criteria, the case data of 2,358 female patients who underwent vaginal microecology and HPV-DNA tests at the same time in the Department of Obstetrics and Gynecology of the First Affiliated Hospital of Xi'an Jiaotong University from May 2021 to March 2022 were retrospectively analyzed. The population was divided into two groups: an HPV-positive group and an HPV-negative group. HPV-positive patients were further classified into HPV16/18-positive group and HPV other subtypes positive group. The vaginal microecology of HPV-infected patients was analyzed using the chi-square test, Fisher's exact test, and logistic regression. Results Among the 2,358 female patients, the HPV infection rate was 20.27% (478/2,358), of which the HPV16/18 infection rate was 25.73% (123/478), and the HPV other subtypes infection rate was 74.27% (355/478). The difference in HPV infection rates between the age groups was statistically significant (P < 0.01). The prevalence of mixed vaginitis was 14.37% (339/2,358), with bacterial vaginosis (BV) paired with aerobic vaginitis (AV) accounting for the majority (66.37%). The difference in HPV infection rates among mixed vaginitis was not statistically significant (P > 0.05). The prevalence of single vaginitis was 24.22% (571/2,358), with the most frequent being vulvovaginal Candidiasis (VVC; 47.29%, 270/571), and there was a significant difference in HPV infection rates among single vaginitis (P < 0.001). Patients with BV had a higher risk of being positive for HPV16/18 (OR: 1.815, 95% CI: 1.050-3.139) and other subtypes (OR: 1.830, 95% CI: 1.254-2.669). Patients with Trichomoniasis were at higher odds of other HPV subtype infections (OR: 1.857, 95% CI: 1.004-3.437). On the contrary, patients with VVC had lower odds of becoming infected with other HPV subtypes (OR: 0.562, 95% CI: 0.380-0.831). Conclusion There were disparities in HPV infection among different age groups; therefore, we should pay attention to the prevention and treatment of susceptible individuals. BV and Trichomoniasis are linked to HPV infection; hence, restoring the balance of vaginal microecology could assist in the prevention of HPV infection. As a protective factor for other HPV subtype infections, VVC may provide new insights into the development of immunotherapeutic therapies.

The vaginal microbiota of women living with HIV on suppressive antiretroviral therapy and its relation to high-risk human papillomavirus infection. BMC Microbiol 2023; 23:21. [PMID: 36658503 PMCID: PMC9850673 DOI: 10.1186/s12866-023-02769-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2022] [Accepted: 01/11/2023] [Indexed: 01/20/2023] Open
Abstract
BACKGROUND Few studies have investigated the vaginal microbiota (VM) in women living with HIV (WLWH) in the context of high-risk human papillomavirus (HR-HPV) infection, even though WLWH are at an increased risk of HPV-related malignancies, including cervical cancer. To explore the impact of HIV and HPV infection on the VM in WLWH, we determined the prevalence of HR-HPV infection and cervical cytologic abnormalities in a cohort of 44 WLWH and 39 seronegative-women (SNW), characterized the vaginal microbiota by 16S sequencing, assessed genital inflammation and systemic immune activation by multiplex bead assay and flow cytometry, respectively. Finally, we explored relationships between bacterial richness and diversity, the top 20 bacterial genera, genital inflammation and systemic immune activation. RESULTS We found that HR-HPV prevalence was similar between WLWH and SNW. High-grade squamous intraepithelial lesions (HSIL) were only detected in WLWH negative for HR-HPV infection. In regression analyses, no risk factors were identified. Women co-infected with HIV and HR-HPV had the highest level of systemic immune activation, and these levels were significantly different compared with SNW without HR-HPV infection. Lactobacillus iners was the dominant Lactobacillus species in WLWH and SNW alike. CONCLUSION We found no evidence of differences in vaginal microbial richness and diversity, microbial community structure, and genital inflammation by HIV, HPV, or HIV and HPV status.

[PMID: 37751562 PMCID: PMC10524074 DOI: 10.1177/10732748231202925] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2023] [Revised: 07/23/2023] [Accepted: 08/25/2023] [Indexed: 09/28/2023] Open
Abstract
BACKGROUND A persistent infection by high-risk human papillomavirus (HR-HPV) is a prerequisite for the development of cervical neoplasms; however, most studies have focused on risk factors associated with HPV-16 and HPV-18 only. OBJECTIVES We assessed the association of risk factors with the prevalence of HPV-16, HPV-18, and non-16/18 HR-HPV infection and with the occurrence of cervical lesions in the baseline of a cohort study of HPV persistence in a Mexican population. METHODS Cross-sectional study within the baseline of a 5-year dynamic cohort study of HR-HPV persistence in women with an abnormal cytology study result from 2015 to 2021. HPV DNA was detected using the Anyplex II HPV 28 kit. Data on lifestyle, sociodemographic, and reproductive factors were assessed using bivariate and multivariate analyses to determine the association of risk factors with HR-HPV infection status and histopathologic diagnosis. RESULTS A total of 373 women were included in the study. The overall prevalence of HR-HPV infection was 69.97%. The most prevalent HR-HPV genotypes, including single and multiple infections, were HPV-53 (13.4%), HPV-16 (11.8%), HPV-58 (10.9%), HPV-31 (10.9%), and HPV-66 (10.7%). We found 90 multiple HR-HPV infection patterns, all of them with α-6 and -9 species. Significant associations of multiple HPV-16 and non-16/18 HR-HPV infections were found with marital status, number of lifetime sexual partners, and smoking history. The most prevalent genotype in CIN1 and CIN2 patients was HPV-16. No association was found between biological plausibility risk factors and cervical lesions. CONCLUSIONS The risk factors for non-16/18 HR-HPV multiple infections are no different than those linked to HPV-16 multiple infections.

Abstract
Cervical cancer is the most common gynecological malignancy and screening for risk factors with early detection has been shown to reduce the mortality. In this study, we aimed to analyze the characteristics and risk factors of human papillomavirus (HPV) infection and precancerous lesions in women and provide clinical evidence for developing strategies to prevent cervical precancerous lesions and cancer in women. Furthermore, we evaluated the influencing factors for high-risk HPV infection. From April 2018 to December 2021, 10,628 women were recruited for cervical cancer screening at Liaoning Cancer Hospital, Shenyang Sujiatun District Women’s and Infants Hospital, Benxi Manchu Autonomous County People’s Hospital, and Shandong Affiliated Hospital of Qingdao University. The study participants were tested to determine if they were HPV-positive (HPV +) or underwent thinprep cytology test (TCT) for atypical squamous cells of undetermined significance (ASCUS) and above. Furthermore, colposcopies and biopsies were performed for the histopathological examination. Finally, 9991 cases were included in the statistical analysis, and the factors influencing HPV infection and those related to cervical cancer and precancerous lesions were analyzed. HPV + infection, high-grade squamous intraepithelial lesion-positive (CINII +) in cervical high-grade intraepithelial neoplasia, and early cervical cancer diagnosis rates were 12.45, 1.09, and 95.41%, respectively. The potential risk factors for HPV were education ≤ high school [odds ratio (OR) = 1.279 (1.129–1.449), P < 0.001], age at initial sexual activity ≤ 19 years [OR = 1.517 (1.080–2.129), P = 0.016], sexual partners > 1 [OR = 1.310 (1.044–1.644), P = 0.020], ASCUS and above [OR = 11.891 (10.105–13.993), P < 0.001], non-condom contraception [OR = 1.255 (1.059–1.487), P = 0.009], and HSIL and above [OR = 1.541 (1.430–1.662), P < 0.001]. Compared with women aged 56–65 and 35–45 years [OR = 0.810 (0.690–0.950), P = 0.010] the HPV infection rate was significantly lower in those aged 46–55 years [OR = 0.79 (0.683–0.915), P = 0.002]. Furthermore, ≤ high school age [OR = 1.577 (1.042–2.387), P = 0.031], not breastfeeding [OR = 1.763 (1.109–2.804), P = 0.017], ASCUS and above [OR = 42.396 (28.042–64.098), P < 0.001] were potential risk factors for cervical cancer and precancerous lesions. In women with HPV infection, ≤ high school education level, initial sexual activity at ≤ 19 years of age, number of sexual partners > 1, ASCUS and above, non-condom contraception, HSIL and above were risk factors for HPV infection. Compared with women aged 56–65 years, those aged 35–45 and 46–55 years had significantly lower HPV infection rates, and high school age and below, non-breastfeeding, and ASCUS and above were all potential risk factors for cervical cancer and precancerous lesions.

Abstract
OBJECTIVE To determine the efficacy and safety of 5-aminolevulinic acid-mediated photodynamic therapy (ALA-PDT) in cervical intraepithelial neoplasia (CIN) infected by HPV. METHODS The clinical data of 115 patients with HPV-Infected CIN admitted to our hospital were selected for this retrospective analysis. They were divided into a control group (n=53) and an experimental group (n=62) according to different treatment methods. Patients in the control group were treated by laser therapy, while those in the experimental group were treated by ALA-PDT. The two cohorts of patients were compared with respect to clinical efficacy, LSIL cure rate, adverse reactions, and complications. Patients were followed up for 3 months and 6 months, and their clinical outcomes were compared based on HPV persistence and residual/recurrent low-grade squamous intraepithelial lesion (LSIL). In the experimental group, the negative conversion rate of HPV and the degree of squamous epithelial lesions in patients with different HPV infection types and various visible degrees of transformation zones (TZs) were compared 6 months after surgery. RESULTS After 6 months of follow-up, the HPV clearance rate and LSIL reversal rate in the control group were 62.3% and 64.2%, respectively, while those in the experimental group were 79.0% and 80.6%, respectively, with significant differences between the two groups (P<0.05). There was no significant difference between the two groups in terms of the LSIL cure rate of lesions located in cervicovaginal region and cervicovaginal region + cervical canal (P>0.05). Neither were there any significant differences in HPV negative conversion rate and LSIL residual/recurrence rate in patients with HPV 16/18 and non-HPV 16/18 between the control group and the experimental group (P>0.05). However, the HPV negative conversion rate in partially visible TZs was lower than that in completely visible TZs, and the LSIL residual/recurrence rate in the completely visible TZs in the control group was higher than that in the experimental group (P<0.05). The incidence of adverse reactions was not significantly different between the two groups (P>0.05), but the incidence of complications in the control group was higher than that in the experimental group (P<0.05). Neither the experimental group nor the control group had any cases of pathologic escalation to high-grade squamous intraepithelial lesion (HSIL). CONCLUSION ALA-PDT can effectively treat HPV-infected CIN and promote HPV clearance.

BMC Infect Dis 2022; 22:340. [PMID: 35382756 PMCID: PMC8985253 DOI: 10.1186/s12879-022-07215-7] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2021] [Accepted: 02/28/2022] [Indexed: 11/10/2022] Open
Abstract
Purpose Knowledge of the prevalence of HPV infection among adolescent and early adult girls is essential to determining the best age for the introduction of HPV vaccine, monitoring vaccine efficacy, and giving insight into determinants of persistent high-risk HPV infection, a necessary cause of cervical cancer. Yet, there have been limited studies of HPV infection among adolescent and early adult girls in low-and-middle-income countries. Methods In this cross-sectional study, we randomly selected 205 girls, aged 9–20 years, from 10 schools in central Nigeria. We obtained informed consent and assent, collected data, and trained participants to self-collect vaginal samples using swab stick. We genotyped HPV using SPF10-DEIA/LiPA25 and analyzed data using Stata 14®. Results The mean (SD) age of the girls was 14.9 (2.3) years. We found HPV in 13.2% of vaginal swabs. The earliest age at which anyHPV and hrHPV infections were detected was 10 and 12 years respectively. The prevalence of any HPV peaked at 16 and 17 years, hrHPV at 16 years, lrHPV at 17 and 18 years and multiple hrHPV 18 years of age. The prevalence of hrHPV infection was 1.5% among the 9–12 years age group, 2.9% among 13–16 years and 3.4% among 17–20 years old. The commonest hrHPV types detected were 52 (3.9%), 18 (1.5%) and 51 (2.4%). The most common lrHPV types was 6 (2.9%). Conclusion The prevalence of HPV infection in these urbanized young girls in Nigeria is high and commences after 9 years of age. HPV vaccination in this population should start at 9 years of age or younger to prevent the establishment of persistent HPV infection. Supplementary Information The online version contains supplementary material available at 10.1186/s12879-022-07215-7. The prevalence of HPV was 13.2% among adolescent girls in Jos, North-Central Nigeria. The earliest age at vaginal HPV infection was 11 years of age. The most predominant hrHPV type in vaginal swab was HPV 52. These findings point to the need for introduction of HPV vaccine starting at 9 years of age among girls in Nigeria to give maximum protection.

Abstract
PURPOSE High-risk human papillomavirus (HR-HPV)-positive but cytology-negative cervical cancer screening results are not uncommon. This study aimed to investigate colposcopy's accuracy and diagnostic value in patients with cytology-negative HR-HPV-positive screening results. METHODS This retrospective study included patients with HR-HPV-positive cytology-negative screening results who underwent electronic colposcopy with acetic acid and multi-point cervical biopsy, HPV typing (24 HPV subtypes), and quantitative HPV detection. RESULTS Among 229 patients, 130 had chronic cervicitis, and 99 had cervical lesions (CIN1, n = 37; CIN2/3, n = 55; invasive carcinoma, n = 7). Using colposcopy as a reference, the cervical cytology false-negative rate was 43.2% (99/229). Colposcopy was more accurate in patients with HR-HPV16/18 or high viral loads. Multivariable analyses showed HPV viral load and childbearing history were the independent factors affecting the accuracy of colposcopy (P < 0.05). CONCLUSION Colposcopy in HR-HPV-positive cytology-negative patients has a moderate diagnostic accuracy. The type of cervical transformation zone and HPV viral load are independent factors affecting the accuracy of colposcopy-based diagnosis.

Abstract
In most high‐resource countries with organized screening programs, the incidence and mortality of cervical cancer is decreasing. Recent statistics have also revealed a reduction in invasive cervical cancer incidence as a result of national vaccination programs. Paradoxically, cervical cancer incidence has increased in Japan, particularly amongst women of reproductive age. This study aimed to examine the trends in cervical cancer incidence and mortality for young and middle adult women in Japan, by analyzing trends in 10‐year interval age‐groups. Cervical cancer incidence for young and middle adult women (ages 20‐59 years) was obtained from high‐quality population‐based cancer registries in three prefectures from 1985 to 2015. National cancer mortality data were obtained from published vital statistics from 1985 to 2019. Trends in crude and age‐standardized rates (ASR) were analyzed using Joinpoint regression. The cervical cancer incidence trend in 20‐59‐year‐old women combined significantly increased over the observation period. Both crude and ASR increased from 1985 to 2015 with an annual percent change (APC) of +1.6% (95% confidence interval, 1.1, 2.1) and +1.7% (1.2, 2.3), respectively. Similar increases were seen in ages 20‐29, 30‐39, and 40‐49 years with higher APCs especially in 20s and 30s. Both crude and ASR mortality significantly increased after the early 1990s in ages 20‐59 years combined. Based on the recognition that current cervical cancer control strategies in Japan have not been effective in reducing the cervical cancer burden in young and middle adults, promotion of screening and vaccination should be urgently strengthened.

Cancer Prev Res (Phila) 2021; 15:45-54. [PMID: 34556493 DOI: 10.1158/1940-6207.capr-21-0104] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/08/2021] [Revised: 06/02/2021] [Accepted: 09/08/2021] [Indexed: 11/16/2022]
Abstract
The study aimed to compare the performance of human papillomavirus (HPV)-based strategies to cytology for detecting cervical intraepithelial neoplasia grade 3 or worse (CIN3+) in routine program in China. The study included 50,434 women ages 30-64 years from January 2015 to December 2019, to assess four strategies: cytology with HPV triage (strategy 1), primary HPV testing with reflex cytology (strategy 2), primary HPV testing with HPV-16/18 genotyping and reflex cytology for non-16-18 high-risk HPV genotypes (strategy 3), and co-testing (strategy 4). The main outcomes were sensitivity for CIN3+ and colposcopy referral rate. Overall, the rates of HPV positivity and cytologic abnormality were 7.0% [95% confidential interval (CI), 6.8-7.2] and 3.5% (95% CI, 3.3-3.6], respectively. The sensitivity for CIN3+ were 88.5% for strategy 4, 83.2% for strategy 3, 64.6% for strategy 1, and 60.1% for strategy 2. The relative sensitivity of strategy 4 and strategy 3 compared with strategy 1 for detecting CIN3+ were 1.38 (95% CI, 1.24-1.54) and 1.29 (95% CI, 1.14-1.46), respectively. The colposcopy referral rates of strategies 4 and 3 were significantly higher than that of strategy 1 (2.4% and 2.2% vs. 1.4%, P < 0.001). In conclusion, co-testing and primary HPV testing with HPV-16/18 genotyping and reflex cytology improved the sensitivity for CIN3+ compared with cytology but increased the colposcopy referral rate. Long-term negative predicted value for HPV-negative women should be studied to determine the screening interval. Our study provides further evidence to the introduction of HPV-based strategies in China. PREVENTION RELEVANCE: Both co-testing and primary HPV testing with HPV-16/18 genotyping and reflex cytology triage provided higher sensitivity for detecting CIN3+; however, the number of colposcopy referrals also increased compared with cytology in a routine program. It has great public health implications for the introduction of HPV-based screening strategies in China.

Liu W, Wu Z, Wang L, Wang Q, Sun X, Niu S. Knockdown of TRIM11 suppresses cell progression and apoptosis of cervical cancer cells via PI3K/AKT pathway. Am J Transl Res 2021; 13:10328-10340. [PMID: 34650700 PMCID: PMC8507035] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2021] [Accepted: 06/28/2021] [Indexed: 06/13/2023]
Abstract
OBJECTIVE To detect the expression pattern of TRIM11 in CC and to investigate the effect of TRIM11 knockdown on CC progression. METHODS First, the expression pattern and function of TRIM11 in CC were inferred by GEPIA database. The expression of TRIM11 in CC tissues and cells was verified by RT-qPCR and Western blot assays. TRIM11 shRNA was transfected into CC cells. The effect of TRIM11 knockdown on CC cell proliferation and cell apoptosis was assessed by CCK-8 assay, clone formation test and flow cytometry (FCM). Furthermore, the effect of TRIM11 knockdown on cell migration and invasion was measured by Transwell assay. The apoptosis-related proteins (Bax, Bcl-2 and Cleaved caspase 3) and PI3K/AKT pathway-related proteins (PI3K, p-PI3K, AKT and p-Akt) were examined by Western blot assay. RESULTS TRIM11 was found to be dramatically upregulated in CC tissues and cells. Besides this, TRIM11 was closely related to FIGO stage, infiltration depth and metastasis. Moreover, high expression of TRIM11 was found to be associated with poor prognosis of CC patients. Functional experiments showed that knockdown of TRIM11 obviously suppressed CC cell proliferation, migration and invasion, while accelerated cell apoptosis. In addition, the PI3K inhibitor (LY294002) was used to assess the connection between PI3K/AKT pathway and TRIM11 in CC cells. We found that TRIM11 overexpression suppressed the phosphorylation of PI3K and AKT in CC cells. CONCLUSION Hence, TRIM11 regulates CC cell progression by modulating PI3K/AKT pathway. The results suggested that TRIM11 might be a possible target for the diagnosis and prognosis of CC patients.

Abstract
Owing to the presence of known tumor-specific viral antigens, human papillomavirus (HPV)-associated cancers are well suited for treatment with immunotherapy designed to unleash, amplify or replace the T cell arm of the adaptive immune system. Immune checkpoint blockade designed to unleash existing T cell immunity is currently Food and Drug Administration approved for certain HPV-associated cancers. More specific immunotherapies such as therapeutic vaccines and T cell receptor-engineered cellular therapy are currently in clinical development. Such therapies may offer more specific immune activation against viral tumor antigens and decrease the risk of immune-related adverse events. Current and planned clinical study of these treatments will determine their utility in the treatment of patients with newly diagnosed advanced stage or relapsed HPV-associated cancer.

Abstract
Few studies provide detailed findings about the health disparities of women being told by a physician whether they have ever had a human papillomavirus (HPV) infection. This study sought to characterize the prevalence and characteristics associated with women age 18 to 59 years in the United States who report being told they were infected with HPV. This study used data from the National Health and Nutritional Examination Survey. Descriptive statistics were computed on study variables and multiple logistic regression analyses were conducted to explore the association of the study variables with the outcome variable. Sampling weights were applied to produce national estimates of prevalence. The sample consisted of 1,669 females, representative of 75,107,170 females in the United States population. Around 11.5% reported being told that they had an HPV infection, of which 60.9% were White, and 82.9% were born in the United States. White women are 2.0 times more likely to be told they have HPV than Asian women and 2.8 times more likely than Black women. United States-born women were 2.1 times more likely told they had an HPV infection than those foreign born. This study found that among U.S. women, less than 12% reported ever having been told they have had an HPV infection. Epidemiologic findings suggest gaps between ever being told of a previous infection and being diagnosed with a clinically relevant HPV infection. Despite epidemiologic data indicating higher HPV prevalence among those less educated and women of color, these groups were less likely to report ever being told they have an HPV infection than White women, and those with a college degree suggesting communication gaps among these subgroups about HPV infection that might exist. Strategies to address potential gaps in communication among these subgroups can potentially reduce the economic burden and health disparities related to HPV infection.

Abstract
HPVs representing the most common sexually transmitted disease are a group of carcinogenic viruses with different oncogenic potential. The immune system and the vaginal microbiome represent the modifiable and important risk factors in HPV-induced carcinogenesis. HPV infection significantly increases vaginal microbiome diversity, leading to gradual increases in the abundance of anaerobic bacteria and consequently the severity of cervical dysplasia. Delineation of the exact composition of the vaginal microbiome and immune environment before HPV acquisition, during persistent/progressive infections and after clearance, provides insights into the complex mechanisms of cervical carcinogenesis. It gives hints regarding the prediction of malignant potential. Relative high HPV prevalence in the general population is a challenge for modern and personalized diagnostics and therapeutic guidelines. Identifying the dominant microbial biomarkers of high-grade and low-grade dysplasia could help us to triage the patients with marked chances of lesion regression or progression. Any unnecessary surgical treatment of cervical dysplasia could negatively affect obstetrical outcomes and sexual life. Therefore, understanding the effect and role of microbiome-based therapies is a breaking point in the conservative management of HPV-associated precanceroses. The detailed evaluation of HPV capabilities to evade immune mechanisms from various biofluids (vaginal swabs, cervicovaginal lavage/secretions, or blood) could promote the identification of new immunological targets for novel individualized diagnostics and therapy. Qualitative and quantitative assessment of local immune and microbial environment and associated risk factors constitutes the critical background for preventive, predictive, and personalized medicine that is essential for improving state-of-the-art medical care in patients with cervical precanceroses and cervical cancer. The review article focuses on the influence and potential diagnostic and therapeutic applications of the local innate immune system and the microbial markers in HPV-related cancers in the context of 3P medicine.

Abstract
BACKGROUND Persistent infection with a subset of human papillomavirus (HPV) genotypes can cause abnormal cytology and invasive cervical cancer. This study examines the circulating HPV genotype strains in a local population of the province of Alberta (a largely unvaccinated population) to establish baseline frequency of vaccine and non-vaccine genotypes causing abnormal cervical cytology. METHOD Remnant liquid-based cytology specimens from the Alberta Cervical Cancer Screening Program (March 2014-January 2016) were examined. Only specimens from women who had a cytology grading of atypical squamous cells of undetermined significance or higher were included. HPV genotype was determined for all samples, and results were stratified by demographics and cytology results. RESULTS Forty-four unique HPV genotypes were identified from 4,794 samples. Of the 4,241 samples with a genotype identified, the most common genotypes were HPV 16, 18, 31, and 51, with 1,599 (37.7%), 441 (12.2%), 329 (7.8%), and 354 (8.4%), respectively. HPV9 vaccine genotypes made up 73.2% of these genotyped samples. Compared with specimens in which HPV9 vaccine genotypes were not detected, those with a genotype covered by the HPV9 vaccine were from younger women (33 [interquartile range {IQR] 28 to 42] y versus 40 [IQR 32 to 51] y; p < 0.00001). CONCLUSIONS The baseline distribution of HPV genotypes in this largely unvaccinated population indicates that the HPV9 vaccine provides good protection from high-risk HPV infections. Determining the frequency of genotypes causing abnormal cytology in this population post-vaccine implementation will be important to assess efficacy of vaccination and monitor for any potential genotype replacement.

Abstract
We aimed to study the infection status and distribution of human papillomavirus (HPV) in Yangzhou City to provide precise guidance for the prevention and treatment of cervical cancer in this area. Reproductive tract secretions were collected from patients admitted at Subei People's Hospital over the past 3 years. Fifteen high-risk HPV (HR-HPV) genotypes were analyzed by fluorescent polymerase chain reaction. The positive rate of HR-HPV in 34 420 subjects was 23.56%. There was no significant difference in the rate of overall infection between males and females (χ 2 = 0.04; p = 0.952 > 0.05). The five genotypes with high infection rates in the population were HPV52, HPV58, HPV16, HPV51, and HPV39. Single infection was found to be dominant, primarily with the HPV52 genotype. The infection rate was higher in patients less than 20 years old and more than 60 years old. Most patients with cervical intraepithelial neoplasms 2/3 and cervical cancer were infected by HPV16, followed by those infected by HPV52 and HPV58. There was a significant difference in the infection rate of HPV16 among patients with different cervical lesions (χ 2 = 31.660; p < 0.01), and the infection rate of HPV16 was higher in patients with cervical cancer than in healthy individuals. Single infection was dominant among the study patients with HPV infection in Yangzhou city. There was no significant difference in infection rate and genotype distribution between males and females. The infection rate in young and old women was higher, and the rate increased with age (>20 years).

Prevalence and genotype distribution of HPV infection among 214,715 women from Southern China, 2012-2018: baseline measures prior to mass HPV vaccination. BMC Infect Dis 2021; 21:328. [PMID: 33827456 PMCID: PMC8028771 DOI: 10.1186/s12879-021-06019-5] [Citation(s) in RCA: 19] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2020] [Accepted: 03/28/2021] [Indexed: 12/12/2022] Open
Abstract
Background The epidemiology on the human papillomavirus (HPV) among females in Southern China is not well-established. Baseline data on the prevalence of HPV infection in China prior to mass prophylactic HPV vaccination would be useful. Thus, this study aims to determine the type-specific HPV prevalence and distribution among females from Southern China prior to mass HPV vaccination. Methods A retrospective cross-sectional study employing 214,715 women attending ChenZhou NO.1 People’s Hospital for cervical screening during 2012–2018 was conducted prior to widespread HPV vaccination. HPV genotype was detected using nucleic acid molecular diversion hybridization tests. The overall prevalence, age-specific prevalence, type distribution, and annual trend were analyzed. Results The overall HPV prevalence was 18.71% (95% confidence interval [CI], 18.55–18.88%) among Southern China females. During 2012–2018, the prevalence of HPV infection showed a downward tendency, from 21.63% (95% CI, 21.07–22.20%) in 2012 to 18.75% (95% CI, 18.35–19.16%) in 2018. Age-specific HPV distribution displayed a peak at young women aged less than 21 years (33.11, 95% CI, 31.13–35.15%), 20.07% (95% CI, 19.70–20.44%) among women aged 21–30 years, 17.29% (95% CI, 17.01–17.57%) among women aged 31–40 years, 17.23% (95% CI, 16.95–17.51%) among women aged 41–50 years, 21.65% (95% CI, 21.11–22.20%) among women aged 51–60 years, and 25.95% (95% CI, 24.86–27.07%) among women aged over 60 years. Of the 21 subtypes identified, the top three prevalent high-risk HPV (HR-HPV) genotypes were HPV52 (5.12%; 95% CI, 21.11–22.20%), − 16 (2.96%; 95% CI, 2.89–3.03%), and − 58 (2.51%; 95% CI, 2.44–2.58%); the predominant low-risk HPV (LR-HPV) genotypes were HPV81 (1.86%; 95%CI, 1.80–1.92%) and − 6 (0.69%; 95% CI, 0.66–0.73%) respectively. Incidence of HR-HPV only, LR-HPV only and mixed LR- and HR-HPV were 15.17, 2.07 and 1.47% respectively. Besides, single HPV infection accounted for 77.30% of all positive cases in this study. Conclusions This study highlights 1) a high prevalence of HPV infection among females with a decreasing tendency towards 2012–2018, especially for young women under the age of 21 prior to mass HPV vaccination; 2) HPV52, − 16 and − 58 were the predominant HPV genotypes, suggesting potential use of HPV vaccine covering these HPV genotypes in Southern China.

Abstract
BACKGROUND The causative agent of cervical cancer referred to as Human papillomavirus (HPV) remains a real public health problem. Many countries in West Africa, such as Togo have no data on the high-risk HPV (HR-HPV) infection and genotypes distribution. In order to fill the knowledge gap in the field in Togo, the main objective of this study was to determine the prevalence of pre-cancerous lesions of the cervix and HR-HPV genotypes among Togolese women. METHODS Samples were collected from 240 women by introducing a swab in the cervix. Then, the screening of precancerous cervical lesions using the visual inspection with acetic acid and lugol (VIA / VIL) was conducted. The HR-HPV genotypes were characterised by real-time multiplex PCR. RESULTS Out of 240 women recruited, 128 (53.3%) were infected by HR-HPV. The most common genotypes were HPV 56 (22.7%), followed by HPV 51 (20.3%), HPV 31 (19.5%), HPV 52 (18.8%) and HPV 35 (17.2%). The least common genotypes were HPV 33 (2.3%) and HPV 16 (2.3%). Among the women, 1.3% (3/240) were positive to VIA/VIL. CONCLUSION This study allowed HR-HPV genotypes to be characterised for the first time in Lomé, Togo. This will help in mapping the HR-HPV genotypes in West Africa.

[PMID: 33548162 DOI: 10.1002/dc.24708] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/02/2020] [Revised: 01/20/2021] [Accepted: 01/24/2021] [Indexed: 12/24/2022]
Abstract
BACKGROUND Cervical cancer progresses slowly, increasing the chance of early detection of pre-neoplastic lesions via Pap exam test and subsequently preventing deaths. However, the exam presents both false-negatives and false-positives results. Therefore, automatic methods (AMs) of reading the Pap test have been used to improve the quality control of the exam. We performed a literature review to evaluate the feasibility of implementing AMs in laboratories. METHODS This work reviewed scientific publications regarding automated cytology from the last 15 years. The terms used were "Papanicolaou test" and "Automated cytology screening" in Portuguese, English, and Spanish, in the three scientific databases (SCIELO, PUBMED, MEDLINE). RESULTS Of the resulting 787 articles, 34 were selected for a complete review, including three AMs: ThinPrep Imaging System, FocalPoint GS Imaging System and CytoProcessor. In total, 1 317 148 cytopathological slides were evaluated automatically, with 1 308 028 (99.3%) liquid-based cytology slides and 9120 (0.7%) conventional cytology smears. The AM diagnostic performances were statistically equal to or better than those of the manual method. AM use increased the detection of cellular abnormalities and reduced false-negatives. The average sample rejection rate was ≤3.5%. CONCLUSION AMs are relevant in quality control during the analytical phase of cervical cancer screening. This technology eliminates slide-handling steps and reduces the sample space, allowing professionals to focus on diagnostic interpretation while maintaining high-level care, which can reduce false-negatives. Further studies with conventional cytology are needed. The use of AM is still not so widespread in cytopathology laboratories.

Photodiagnosis Photodyn Ther 2021; 33:102174. [PMID: 33401021 DOI: 10.1016/j.pdpdt.2020.102174] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2020] [Revised: 12/22/2020] [Accepted: 12/23/2020] [Indexed: 12/16/2022]
Abstract
Cervical carcinoma is the most common gynecological cancer among young and adult women. There has been increasing interest in natural sources for cervical carcinoma treatment, especially for active compounds from plant extracts as antineoplastic agents. Berberine is an example of one these promising natural products. It is a natural isoquinoline alkaloid and comes from plants, such as Berbis, Coptis, and Hydrastis. It is widely used in Chinese medicine and has demonstrated activity against various cancer cell lines. This work aims to analyze the efficiency of berberine-containing nanoemulsions as photosensitizing agents in photodynamic therapy and their interaction with cervical carcinoma cells and immortalized human keratinocyte cell line. Among all groups tested, berberine nanoemulsions combined with photodynamic therapy induced the most statistically significant phototoxicity in the evaluated cell lines. Fluorescence microscopy demonstrated that the compound was present for up to 48 h when berberine nanoemulsions were used. The reactive oxygen species assay showed an increase in reactive oxygen species in the two studied cell lines after treatment of berberine-containing nanoemulsion combined with photodynamic therapy. The autophagy trial showed significant increases in cell death when berberine-containing nanoemulsion treatment was combined with photodynamic therapy when compared to trichostatin A treatment as a positive control. However, caspase-3 activity did not significantly increase in cervical carcinoma cells and immortalized human keratinocyte cell line. The results suggest that nanoemulsions with berberine have potential for use as photosensitizing agents in photodynamic therapy to treat cervical carcinoma.

Abstract
Human papillomavirus (HPV) infection has a key role in the development of cervical cancer. The present study aimed to determine the HPV type distribution among females of Uyghur ethnicity in Xinjiang province, northwest China. A total of 12,165 individuals aged 30-79 years from 12 villages in Zepu County, Kashgar Prefecture, Xinjiang province were recruited for screening. Cervical and vaginal swabs from each subject were collected by gynecologists and tested for HPV DNA using Luminex xMAP technology. The results indicated that the overall HPV prevalence was 9.34% (1,136/12,165) in the present cohort; 7.41% (901/12,165) of the individuals were positive for high-risk type HPV (HR-HPV) and 1.64% (200/12,165) were positive for multiple types. Among the individuals who tested positive for HR-HPV types, the three most prevalent types were HPV16 (2.83%), HPV31 (0.99%) and HPV68 (0.88%). Subgroup analysis by age indicated that the highest frequency of HPV infections occurred in subjects aged >60 years. The most common genotype combinations in subjects with multiple types were HPV16 + HPV54, HPV16 + HPV31 and HPV16 + HPV68. The present study provided data on the prevalence and type distribution of HPV infections among Uyghur females in Xinjiang province, northwestern China, which will assist in the assessment of the potential cost-effectiveness of HPV screening and vaccination in this population. The data will also facilitate the determination of HPV68 and 54 strains that should be included in the multi-type vaccine and the establishment of a vaccination program that caters for the different age groups of the Uyghur population.

Abstract
Abstract
Objective The aim of the present work was to evaluate the folate-receptor 1 (FOLR1) expression in cervical squamous cell carcinoma and its clinical significance.
Methods
FOLR1 mRNA expression level was detected in the cancer genome atlas (TCGA) database for multiple carcinomas. The FOLR1 mRNA relative expression between tumor tissue and normal cervix tissue of the cervical squamous cell cancer patients was compared by the online data analysis tool of GEPIA. The overall survival (OS) and progression free survival (PFS) between the FOLR1 high and low expression groups were compared by the log-rank test. Thirty one cervical squamous cancer patients and 20 healthy controls were included in and tested for serum FOLR1 protein level detection. Eighty one cervical squamous cell cancer patients who received surgery were included for FOLR1 protein expression detected by immunohistochemistry assay (IHC). The correlation between FOLR1 protein expression and patients’ clinical features was analyzed.
Results
FOLR1 mRNA was up-regulated in tumor tissue compared to corresponding normal cervical tissue of cervical squamous cell carcinoma. Top 20 genes interacted with FOLR1 was identified through the network with the edges of 146. UBXN10 (r=0.668, P<0.01) and GBP6 (r-=0.606, P<0.01) were the top 2 genes that most correlated with FOLR1. The serum level of FR-α (FOLR1 coding protein) were 275.50±83.79 and 161.70±66.62 (ng/L) for the cervical cancer and healthy control subjects respectively with significant statistical difference (P<0.05). Using the serum FR-α as serological marker for cervical cancer detection, the diagnostic sensitivity, specificity and AUC were 80.0% (58.40% to 91.93%), 80.65% (63.72% to 90.81%) and 0.85(95%CI:0.74-0.96), respectively. Immunohistochemical assay indicated that of the 81 cancer tissue samples, 45 (55.6%) was FOLR1 protein positive. FOLR1 protein positive expression rate in FIGO stage Ⅲ/Ⅳ was significant higher than in the stage Ⅰ/Ⅱ with statistical difference (P<0.05). The progression free survival (PFS) was significant different between FOLR1 high and low expression group (HR=2.48, 95%CI:1.1-5.58, P=0.023). However, the overall survival (OS) was not statistical different between the two groups (HR=1.34, 95%CI:0.84-2.15, P=0.22).
Conclusion: FOLR1 was up-regulated in both serum and cancer tissue of cervical squamous cell carcinoma which may act as diagnostic and prognostic maker for cervical squamous cell cancer.
