Clinical Outcomes and Treatment Efficacy in Cervical Cancer Patients in the UAE: A Retrospective Cohort Study. Cureus 2024; 16:e64422. [PMID: 39131041 PMCID: PMC11317079 DOI: 10.7759/cureus.64422] [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: 06/28/2024] [Accepted: 07/12/2024] [Indexed: 08/13/2024] Open
Abstract
Background and objectives Cervical cancer remains a significant global health issue, particularly in low- and middle-income countries. While high-income countries have seen reduced incidence and mortality rates due to effective screening and HPV vaccination programs, these rates are still high in areas with limited healthcare infrastructure. In the United Arab Emirates (UAE), recent efforts are improving public health initiatives and awareness. This retrospective cohort study evaluates clinical outcomes and treatment efficacy in cervical cancer patients at a tertiary cancer center in Al Ain, Abu Dhabi. It analyzes treatment regimens, their effectiveness, and factors affecting survival, disease progression, and treatment completion. Methods and material The study included 275 cervical cancer patients treated between January 2008 and December 2021. Data were extracted from medical records, including demographic information, clinical characteristics, and treatment details. Statistical analyses, including Kaplan-Meier survival curves and Cramér's V correlation matrix, were used to evaluate survival outcomes and the relationships between various categorical variables. Results The mean age of patients was 48.88 years, with the majority being non-nationals, 221 (80.37%). Histopathologically, there were 234 (85.18%) cases of squamous cell carcinoma (SCC) and 33 (11.85%) cases of adenocarcinomas. The International Federation of Gynecology and Obstetrics (FIGO) staging indicated that 137 (49.80%) patients were in stage II and 60 (21.81%) were in stage III. Pelvic lymph node involvement was observed in 139 (50.54%) patients. The treatment modalities included surgery in 39 (14.18%) patients, 3D conformal radiotherapy (3D-CRT) in 247 (89.81%) patients, intensity-modulated radiation therapy (IMRT) in 11 (4.00%) patients, brachytherapy in 213 (77.45%) patients, and chemotherapy in 248 (90.18%) patients. The survival analysis showed no significant differences in survival among different treatment groups, as indicated by the Log-rank test (p = 0.4060). Conclusion The study highlights the demographic and clinical characteristics of cervical cancer patients in the UAE, emphasizing the prevalence of advanced-stage diagnoses and high-grade tumors. Despite significant efforts to improve screening and treatment, cervical cancer remains a concern in the UAE. The findings underscore the need for enhanced early detection and comprehensive treatment strategies. Addressing the study's limitations, such as the retrospective design and the absence of human papillomavirus (HPV) data, could further refine cervical cancer management and improve patient outcomes in future research.

Risk of Cervical Abnormalities for Women With Multiple Sclerosis Treated With Moderate-Efficacy and High-Efficacy Disease-Modifying Therapies. Neurology 2024; 102:e208059.

Abstract
BACKGROUND AND OBJECTIVES The impact of immunomodulatory therapies on the risk of cervical pre-cancer and invasive cancer development is important for the health and safety of women with multiple sclerosis (wwMS). We investigate the risk of cervical abnormalities in wwMS treated with disease-modifying therapies (DMTs). METHODS This is a multicenter cohort study with data collected from 1998 to 2019 in Victoria, Australia. Data linkage was performed using matching records from the MSBase Registry, the National Human Papillomavirus (HPV) Vaccination Program Register, and the Victorian Cervical Cytology Register. The primary outcome was the detection of any type of cervical abnormality as determined by cytology or histology. Survival methods were used to assess the time to cervical abnormality detection on cervical screening tests (CSTs). Crude and adjusted Cox proportional hazards models were used to determine time to and magnitude of association of DMTs with the risk of cervical abnormality. In a sensitivity analysis, we constructed standardized survival curves averaged over the same set of covariates to determine the commensurate population-average (marginal) causal effects. RESULTS We included 248 wwMS. The incidence of abnormal CSTs was lower (p < 0.001) for women not exposed to moderate-high-efficacy therapy (10.2 per 1,000 patient-years [95% confidence interval (CI) 5.5-14.9]), compared with those exposed (36.6 per 1,000 patient-years [95% CI 21.7-51.6]). Exposure to higher efficacy treatment was associated with a 3.79-fold increased hazard (95% CI 2.02-7.08, p < 0.001) of developing a cervical abnormality relative to those not exposed. When adjusted for vaccination status, smoking, hormonal contraceptive use, and socioeconomic status, the risk remained elevated at 3.79 (95% CI 1.99-7.21, p < 0.001). Marginal hazard ratios declined over time, ranging from 3.90 (95% CI 2.09-7.27) at 20 years of age to 2.06 (95% CI 1.14-3.73) at 70 years of age. DISCUSSION A greater than three-and-a-half-fold increased risk of cervical abnormalities was found after exposure to moderate-high-efficacy DMTs. This risk persisted despite adjusting for HPV vaccination status, hormonal contraception use, smoking, and socioeconomic status. If confirmed in future studies, we would advocate for wwMS exposed to moderate-high-efficacy DMTs to be treated in line with immune-deficient paradigm in cervical screening and HPV vaccination programs. CLASSIFICATION OF EVIDENCE This study provides Class III evidence that highly active MS therapy compared with less active therapy increases the risk of developing cervical abnormalities among women with MS.

Abstract
PURPOSE The association between second-hand smoke (SHS) exposure and cervical cancer (CC) risk is still unclear. The aim of this study is to provide an accurate and updated estimate of this association. METHODS Through an original methodology to identify original publications, we conducted a systematic review and meta-analysis of all epidemiological studies published up to October 2022 evaluating the association between SHS exposure and CC risk among female non-smokers. Meta-analytic estimates were obtained using random-effects models and dose-response relationships were derived using log-linear functions. RESULTS Out of 25 eligible studies, 21 were included in the meta-analysis, providing a pooled relative risk (RR) of cervical intraepithelial neoplasia (CIN) of grade 2 or higher of 1.52 (95% confidence interval, CI 1.30-1.78, 21 studies) for overall SHS exposure versus non-exposure. When restricting the analysis to invasive CC, the pooled RR was 1.42 (95% CI 1.17-1.71, 13 studies), whereas the pooled RR for CIN was 1.50 (95% CI 1.22-1.84, 6 studies). Analyzing RR by setting or source of SHS exposure resulted in significant associations with CC risk for SHS exposure at home (RR for CIN2+ 1.49, 95% CI 1.21-1.84, 14 studies), in non-specified settings (RR for CIN2+ 1.64, 95% CI 1.20-2.23, 8 studies) and from partner (RR for CIN2+ 1.55, 95% CI 1.25-1.94, 10 studies). The risk of CIN2+ significantly increased linearly with the intensity and pack-years of SHS exposure. CONCLUSION This comprehensive review and meta-analysis confirmed the association of SHS exposure with CC, further suggesting the need to raise concern about SHS exposure in the population.

Abstract
Cervical cancer is the second most common cancer among women under 50 years of age in Pakistan. The current study was designed to assess the level of awareness through educational outreach presentations about cervical cancer, Papanicolaou (Pap) smear test, and human papillomavirus (HPV) vaccination in Karachi, Pakistan. Women from different urban hospitals were enrolled. Participants participated in a 45-minute presentation on cervical cancer awareness led by student pharmacists from Nazeer Hussain University, Karachi. A pre-and post-test was administered to assess the impact of the intervention. Descriptive statistics were used to summarize the findings, and a t-test was used for matched comparison, and a p-value <0.05 for statistical significance. A total of 150 women participated in the study. The study found that Pakistani women living in urban settings were less knowledgeable about the causes of cervical cancer and prevention. After the presentation, we observed a 45% increase in knowledge, and 31% of participants said they would obtain a Pap smear test in the next six months. Supervised pharmacy student-led presentations on cervical cancer educational awareness that significantly impacted women participants. Pharmacists can play a key role in reducing cervical cancer deaths through increased awareness, education, prevention, and immunization.

Abstract
Cervical cancer is a significant cause of female mortality worldwide, and early detection through regular screening is crucial for reducing mortality rates. However, in developing countries, the uptake of Pap smear tests (PST) is low, mostly due to cultural and social factors and a lack of knowledge. This cross-sectional study assessed knowledge, attitude, and practice of cervical cancer screening among practitioners working at primary healthcare centers in Saudi Arabia. Furthermore, the study aimed to identify the potential barriers that prevent female physicians from performing cervical cancer screening tests. A self-administrated, well-structured questionnaire was used to survey 95 female physicians, including residents, specialists, and consultants in several primary health care centers (PHCCs) in Jeddah managed by the Ministry of Health during September 2019. The results showed that 80% of participants knew about cervical cancer, and 97.8% were aware that PST is a screening tool. However, only 47% advised female patients to get tested for cervical cancer. The factors identified as barriers to test uptake included asymptomatic females (34%), lack of time on the part of the practitioner (24%), and a lack of evidence for risk factors (23%). Additionally, only 42.2% of the participating physicians had undergone a Pap smear test themselves. The study highlights the need for further research to assess HPV status in the population and explore the correlation between circumcision and cervical cancer, as well as polygamy and cervical cancer. The findings suggest that while a good level of knowledge about cervical cancer exists, there is a need to improve compliance with cervical cancer screening guidelines among female physicians in Saudi Arabia.

Abstract
Purpose Cervical cancer (CC) is the leading cause of cancer-related death among women living in third-world countries. CC is preventable, with the possibility of complete treatment if detected early. The objective of the study was to assess the level of knowledge, attitude, and practice on CC screening (CCS) among female university students (FUS) in Ishaka, western Uganda. Methods The study was a descriptive cross-sectional study among FUS (n = 407) in western Uganda conducted after the first nationwide lockdown in Uganda. Information was collected using a questionnaire and descriptively presented as frequency and percentages. Results The majority of our respondents were medical students 283 (69.5%), below 25 years 339 (83.3%), with Anglican Christian religious background 150 (36.9%). Respondents above the age of 25 years (p = 0.0052) and those in the medical profession (p < 0.001) had more knowledge. More medical students had a better attitude (p = 0.0043) and favorable practices (0.0134) compared to their non-medical counterparts. There is a weak correlation between attitude (r = 0.206, p < 0.001) and practice (r = 0.181, p = 0.0003) with knowledge on CCS. Conclusion Observation from the present study suggests the need for more efforts in the fight against cervical cancer and encouragement of positive attitude and practice towards cervical cancer screening and uptake of vaccination.

Abstract
INTRODUCTION As it may not be feasible to provide cervical cancer screening services to all HIV-infected women in most resource-limited settings, there is a need to identify those who are most at risk. We determined the prevalence, patterns, and associated factors of cervical cytological abnormalities among HIV-infected women in Lagos, Nigeria. METHODS This descriptive cross-sectional study was conducted among HIV-infected women at the adult HIV treatment and colposcopy clinics of a university teaching hospital in Lagos, Nigeria, between October 2018 and December 2019. A cervical sample was collected from each woman to detect cervical cytological abnormalities. RESULTS Of the 593 enrolled women, cervical cytological abnormalities were present in 40 (6.7%). Most (37.5%) of the women with cytological abnormalities had atypical squamous cells of undetermined significance. Age at coitarche (<20 vs. ≥20 years: adjusted odds ratio, 2.42; 95% confidence interval, 1.21-4.83, p = 0.01) was the only factor that was independently associated with cervical epithelial abnormalities. CONCLUSION The prevalence of cervical cytological abnormalities in our study is lower than most previous reports in Africa. Sexual debut at an early age was significantly associated with cytological abnormalities. It is necessary to confirm the findings of this study through a well-designed and adequately powered longitudinal study.

Influences of cervical cancer screening among a sample of physically active women ages 21-49 living in the United States. Prev Med Rep 2022; 30:101978. [PMID: 36157713 PMCID: PMC9494240 DOI: 10.1016/j.pmedr.2022.101978] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2022] [Revised: 08/31/2022] [Accepted: 09/02/2022] [Indexed: 11/17/2022] Open
Abstract
To achieve the lowest risk level for various cancers, individuals would engage in several healthy lifestyle behaviors and age-eligible cancer screenings as recommended. Nonetheless, research has largely omitted exploration of concurrent primary and secondary prevention behaviors. This study was designed to explore influences of cervical cancer screening among physically active women who reported participation in recreational sports. U.S. based women between the ages of 21–49, who had never been diagnosed with cancer, were eligible to complete a web-based survey. Logistic regression analyses were conducted using SAS 9.4. On average, women were 31 years of age (N = 394) and self-identified as Black (51.3 %). Although low overall (30.7 %), higher odds of cervical cancer screening were associated with age (OR = 1.06, 95 % CI = 1.03–1.10), employment (OR = 2.43, 95 % CI = 1.14–5.18), knowledge of cancer-related risk behaviors (OR = 4.04, 95 % CI = 1.33–12.28), routine doctor’s visit (OR = 4.25, 95 % CI = 1.56–11.54), and team-based vs individual-based sport participation (OR = 1.95, 95 % CI = 1.13–3.34). Our study provides insight into the health profile of physically active women, ages 21–49, as it relates to risks for cervical cancer. Screening uptake among this diverse sample was much lower than the general population and national goals set by Healthy People 2030. Interventions should be tailored to increase knowledge of cancer-related risk behaviors, access to healthcare, and recommended cervical cancer screenings among even assumed-to-be healthy populations.

Abstract
Background Cervical cancer (CC) is the first cause of cancer-related deaths among Cape Verdean women. The absence of a national screening programme and a lack of dedicated cancer treatment facilities contribute to its high mortality rate. In an effort to improve the prognosis of these women, a health cooperation agreement was established between Portugal and Cape Verde (CV), allowing their evacuation to Portuguese hospitals. Our aim was to characterise CC among CV women, and to assess the response given to these patients in Instituto Português de Oncologia de Lisboa Francisco Gentil (IPOLFG), so that their treatment and follow-up protocols can be optimised and overall prognosis improved. Methods Retrospective evaluation of women diagnosed with CC in CV that underwent therapy in IPOLFG between 2013 and 2020. Risk factors, demographic and tumour characteristics, treatment and outcomes were reviewed. Results Fifty-eight patients were included. Squamous cell carcinoma was the most frequent (91.5%) histological type. HPV DNA was present in 25 out of 26 samples.The agreement rate between the pathology analysis performed in CV and in Portugal was high (87.9%); however, the agreement regarding the FIGO stage was low (15.5%). This may be explained by both the time interval between diagnosis and treatment (around 6 months) and by the absence of resources to accurately stage the disease in CV. In IPOLFG, 77.6% of patients received combined chemo-radiotherapy. Post-treatment follow-up varied widely, due to disease-related and bureaucratic issues. Eighteen patients developed cancer-related complications and/or cancer-related death. The survival rate and median overall survival (OS) in our cohort were of 89.7% and 73.2 months, respectively. Conclusions Although most women had advanced-stage disease, the OS in our cohort was better than what has been reported for other African countries, probably because state-of-the-art treatment, frequently not accessible in those countries, was offered to all patients.

Abstract
Human papillomavirus type 16 (HPV16) and/or high-risk (Hr-) HPV are the main causes of cervical cancer. Another element that may contribute to the development of cervical cancer is the microbiota. To date, no study has investigated the entire cervical microbiome, which consists of bacteria, fungi, and viruses. In this study, cervical samples with different histopathology (CIN1, CIN2, and CIN3), with or without HPV16 and Hr-HPVs infection, were enrolled. From bacterial community analysis, 115 bacterial species were found and separated into 2 distinct categories based on Lactobacillus abundance: Lactobacilli-dominated (LD) and non-Lactobacilli-dominated (NLD) groups. The LD group had significantly less bacterial diversity than the NLD group. In addition, the variety of bacteria was contingent on the prevalence of HPV infection. Among distinct histological groups, an abundance of L. iners (>60% of total Lactobacillus spp.) was discovered in both groups. A few fungi, e.g., C. albicans, were identified in the fungal community. The viral community analysis revealed that the presence of HPV considerably reduced the diversity of human viruses. Taken together, when we analyzed all our results collectively, we discovered that HPV infection was a significant determinant in the diversity of bacteria and human viruses in the cervix.

Abstract
Cervical cancer is the fourth most common type of cancer in women. Worldwide, it is a public health problem with around 604,127 women diagnosed per year and 341,831 deaths. Cervical cancer and persistent high-risk human papillomavirus (HPV) infection are highly associated. However, other factors are also involved, such as viral load, HPV variants, sexual behavior, and genetic factors. The host immune response against HPV has been widely studied and it has shown associations with development of cervical cancer. The human leukocyte antigen (HLA) genes are related to the persistence of HPV infection and progression to cervical cancer because of their role in controlling T-cell mediated immune response to clear the infection. In Ecuador, there is scarce information about HLA and HPV infection with high-risk genotypes in the population. This study aimed to identify host-specific HLA alleles in women with cervical intraepithelial neoplasia (CIN) II and III, and cancer infected with HPV-16, 58, and 52. In this study, we included 51 samples previously identified as positive for HPV-16, 58, and 52 from 12 Ecuadorian provinces. As a result, we found that HLA-A*02, HLA-B*35, HLA-C*04, HLA-DRB1*04, and HLA-DQB1*03 alleles were the most frequent, these alleles have been associated with cervical cancer in previous studies; nevertheless, we did not find a statistically significant association between HLA alleles, HPV genotype, and histopathological lesion. This is a baseline study to uncover possible relationships between HLA and HPV to elucidate why this virus can develop a persistent infection in some women leading to the development of cervical cancer.

Abstract
Although other co-viral infections could also be considered influencing factors, cervical human papillomavirus (HPV) infection is the main cause of cervical cancer. Metagenomics have been employed in the NGS era to study the microbial community in each habitat. Thus, in this investigation, virome capture sequencing was used to examine the virome composition in the HPV-infected cervix. Based on the amount of HPV present in each sample, the results revealed that the cervical virome of HPV-infected individuals could be split into two categories: HPV-dominated (HD; ≥60%) and non-HPV-dominated (NHD; <60%). Cervical samples contained traces of several human viral species, including the molluscum contagiosum virus (MCV), human herpesvirus 4 (HHV4), torque teno virus (TTV), and influenza A virus. When compared to the HD group, the NHD group had a higher abundance of several viruses. Human viral diversity appears to be influenced by HPV dominance. This is the first proof that the diversity of human viruses in the cervix is impacted by HPV abundance. However, more research is required to determine whether human viral variety and the emergence of cancer are related.

Abstract
Precancerous lesions of human cervix uteri have a tendency for regression or progression. In cervical intraepithelial neoplasia grade 2 (CINII) case there is an uncertainty if a lesion will progress or regress. The carbonic anhydrase IX (CAIX) enzyme is overexpressed in cervical cancer which is more sensitive to radiotherapy. CAIX is associated with poor prognosis in solid hypoxic tumors. The aim of this study was to determine factors related to elevated soluble CAIX (s-CAIX) in high-grade intraepithelial lesion (HSIL) cases. Methods. Patients diagnosed with HSIL (N = 77) were included into the research group whereas without HSIL (N = 72)—the control group. Concentration of the soluble CAIX (s-CAIX) in plasma was determined by the DIANA ligand-antibody-based method. C. trachomatis was detected from cervical samples by PCR. Primary outcomes were risk factors elevating s-CAIX level in HSIL group. Non-parametric statistical analysis methods were used to calculate correlations. Results. The s-CAIX level in patients with HSIL was elevated among older participants (rs = 0.27, p = 0.04) and with C. trachomatis infection (p = 0.028). Among heavy smokers with HSIL, the concentration of s-CAIX was higher in older women (rs = 0.52, p = 0.005), but was not related to the age of heavy smokers’ controls (τ = 0.18 p = 0.40). Conclusion. The concentration of s-CAIX was higher among older, heavy smoking and diagnosed with C. trachomatis patients. All these factors increased the risk for HSIL progression.

Abstract
PURPOSE Data on heterogeneity in cancer screening and diagnosis rates among lesbians/gays and bisexuals (LGBs) is lacking. Recent studies showed that LGBs have decreased healthcare utilization compared to heterosexual counterparts. Few studies have examined how sexual orientation impacts cancer screening and prevalence. We, therefore, investigated the association between sexual orientation and prevalent sex-specific cancer including prostate (PCa), breast (BC), and cervical (CC) cancer. METHODS This was a cross-sectional survey-based US study, including men and women aged 18 + from the Health Information National Trends Survey (HINTS) database between 2017 and 2019. The primary endpoint was individual-reported prostate, breast, and cervical cancer screening and prevalence rates among heterosexual and LGB men and women. Multivariable logistic regression analyses assessed association of various covariates with undergoing screening and diagnosis of these cancers. RESULTS Overall, 4,441 and 6,333 heterosexual men and women, respectively, were compared to 225 and 213 LGB men and women, respectively. LGBs were younger and less likely to be screened for PCa, BC, and CC than heterosexuals. A higher proportion of heterosexual women than lesbian and bisexual women were screened for CC with pap smears (95.36% vs. 90.48% and 86.11%, p ≤ 0.001) and BC with mammograms (80.74% vs. 63.81% and 45.37%, p ≤ 0.001). Similarly, a higher proportion of heterosexual men than gay and bisexual men were screened for PCa with PSA blood tests (41.27% vs. 30.53% and 27.58%, p ≤ 0.001). CONCLUSION There were more heterosexuals than LGBs screened for CC, BC, and PCa. However, no association between sexual orientation and cancer diagnosis was found. Healthcare professionals should be encouraged to improve cancer screening among LGBs.

Abstract
BACKGROUND Tobacco use is the leading preventable cause of cancer and cancer deaths. Tobacco use is not only related to lung cancer, but has an impact on a wide range of different cancer entities in almost every organ system. OBJECTIVES The aim of this review article is to shed light on the different organ systems involved in tobacco-associated carcinogenesis. MATERIALS AND METHODS For this purpose, first a brief introduction into the topic is given, followed by a detailed description of the different tumor entities associated with tobacco use. RESULTS Tobacco consumption has been clearly implicated in the causation of many types of cancer, affecting multiple organ systems. Based on current evidence, tobacco use can cause cancer of the mouth and throat, larynx, esophagus, stomach, kidney, pancreas, liver, bladder, cervix, colon and rectum, and acute myeloid leukemia. CONCLUSION Tobacco use is not only main cause in the development of lung cancer, but has a major impact in the development of cancer in other organ systems. Therefore, special attention must be given to possible concomitant malignancies when evaluating images of smokers.

Abstract
BACKGROUND The aim of the study was to evaluate if artificial neural networks can predict high-grade histopathology results after conisation from risk factors and their combinations in patients undergoing conisation because of pathological changes on uterine cervix. PATIENTS AND METHODS We analysed 1475 patients who had conisation surgery at the University Clinic for Gynaecology and Obstetrics of University Clinical Centre Maribor from 1993-2005. The database in different datasets was arranged to deal with unbalance data and enhance classification performance. Weka open-source software was used for analysis with artificial neural networks. Last Papanicolaou smear (PAP) and risk factors for development of cervical dysplasia and carcinoma were used as input and high-grade dysplasia Yes/No as output result. 10-fold cross validation was used for defining training and holdout set for analysis. RESULTS Bas eline classification and multiple runs of artificial neural network on various risk factors settings were performed. We achieved 84.19% correct classifications, area under the curve 0.87, kappa 0.64, F-measure 0.884 and Matthews correlation coefficient (MCC) 0.640 in model, where baseline prediction was 69.79%. CONCLUSIONS With artificial neural networks we were able to identify more patients who developed high-grade squamous intraepithelial lesion on final histopathology result of conisation as with baseline prediction. But, characteristics of 1475 patients who had conisation in years 1993-2005 at the University Clinical Centre Maribor did not allow reliable prediction with artificial neural networks for every-day clinical practice.

Abstract
INTRODUCTION Cervical cancer (CC) is the leading cause of cancer-related death among women in sub-Saharan Africa. It occurs most frequently in women living with HIV (WLHIV) and is classified as an AIDS-defining illness. Recent World Health Organisation (WHO) recommendations provide guidance for CC prevention policies, with specifications for WLHIV. We systematically reviewed policies for CC prevention and control in sub-Saharan countries with the highest HIV prevalence. METHODS We included countries with an HIV prevalence ≥ 10% in 2018 and policies published between January 1st 2010 and March 31st 2022. We searched Medline via PubMed, the international cancer control partnership website and national governmental websites of included countries for relevant policy documents. The online document search was supplemented with expert consultation for each included country. We synthesised aspects defined in policies for HPV vaccination, sex education, condom use, tobacco control, male circumcision,cervical screening, diagnosis and treatment of cervical pre-cancerous lesions and cancer, monitoring mechanisms and cost of services to women while highlighting specificities for WLHIV. RESULTS We reviewed 33 policy documents from nine countries. All included countries had policies on CC prevention and control either as a standalone policy (77.8%), or as part of a cancer or non-communicable diseases policy (22.2%) or both (66.7%). Aspects of HPV vaccination were reported in 7 (77.8%) of the 9 countries. All countries (100%) planned to develop or review Information, Education and Communication (IEC) materials for CC prevention including condom use and tobacco control. Age at screening commencement and screening intervals for WLHIV varied across countries. The most common recommended screening and treatment methods were visual inspection with acetic acid (VIA) (88.9%), Pap smear (77.8%); cryotherapy (100%) and loop electrosurgical procedure (LEEP) (88.9%) respectively. Global indicators disaggregated by HIV status for monitoring CC programs were rarely reported. CC prevention and care policies included service costs at various stages in three countries (33.3%). CONCLUSION Considerable progress has been made in policy development for CC prevention and control in sub Saharan Africa. However, in countries with a high HIV burden, there is need to tailor these policies to respond to the specific needs of WLHIV. Countries may consider updating policies using the recent WHO guidelines for CC prevention, while adapting them to context realities.

Front Med (Lausanne) 2022; 9:929062. [PMID: 35795639 PMCID: PMC9251542 DOI: 10.3389/fmed.2022.929062] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2022] [Accepted: 05/30/2022] [Indexed: 11/13/2022] Open
Abstract
Cervical cancer is estimated to cause 341,831 deaths each year, with 9 of 10 deaths occurring in developing countries. Over the past decade, there has been a significant increase in cervical cancer incidence among women in the Philippines. Persistent infection with high-risk human papillomavirus (HPV) is the well-established necessary cause of cervical cancer. Based on limited studies conducted in the Philippines, the prevalence of infection with any HPV genotype was 93.8% for cervical squamous cell carcinoma and 90.9% for cervical adenocarcinomas. HPV types 16 and 18 were the most common HPV genotypes among Filipino patients with cervical cancer. On the other hand, the incidence of HPV infection among Filipino women with normal cervices was 9.2%. The World Health Organization has launched a global agenda of eliminating HPV infection by 2030. One of its key milestones is to vaccinate 90% of girls with the HPV vaccine by 15 years. However, the HPV vaccination rate among Filipino women remains to be unsatisfactory. HPV vaccination has only been included in the Philippine Department of Health's community-based National Immunization Program in 2015. Despite these efforts, the Philippines currently ranks last on HPV program coverage among low-middle income countries, with coverage of only 23% of the target female population for the first dose and 5% for the final dose. The principal reason for the non-acceptance of HPV vaccines was the perceived high cost of vaccination. The low utilization of available cervical cancer screening tests such as Pap smear and visual inspection with acetic acid hampered the Philippines' control and prevention of HPV infection and cervical cancer. Among those diagnosed with cervical cancer in the Philippines, only an estimated 50% to 60% receive some form of treatment. To this end, we summarize the burden of HPV infection and cervical cancer on Filipinos and the risk factors associated with the disease. We present the current screening, diagnostics, treatment, and prevention of HPV-related diseases in the Philippines. Lastly, we also propose solutions on how each building block in health systems can be improved to eliminate HPV infection and reduce the burden of cervical cancer in the Philippines.

Sociodemographic correlates of cervix, breast and oral cancer screening among Indian women. PLoS One 2022; 17:e0265881. [PMID: 35544475 PMCID: PMC9094566 DOI: 10.1371/journal.pone.0265881] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2021] [Accepted: 03/09/2022] [Indexed: 11/19/2022] Open
Abstract
Introduction Cervix, breast and oral cancers account for about one-third of all cancers in India which as a group is a major contributor to all non-communicable disease-related morbidity and mortality among women. Existing evidence suggests that early diagnosis plays a pivotal role in the prevention and intervention of these cancers, and many community-based early screening and awareness programs have been in place in developed countries. Currently, there is not enough research evidence regarding the sociodemographic correlates of cervix, breast and oral cancer screening among Indian women. In the present study, we aimed to assess the self-reported percentage and sociodemographic factors associated with the use of these three types of cancer screening services among Indian women aged 15–49 years. Methods Data were collected from National Family Health Survey conducted during 2015–16. Sample population was 699,686 women aged 15–49 years. Associations between self-reported cervical, breast and oral cancer screening status and the associated sociodemographic factors were analyzed using multivariable logistic regression methods. Results The percentage of screening for cervical (21%), breast (8.95%), and oral cancers (13.45%) varied significantly across the population sub-groups. Higher age, urban residence, higher education, having employment, health insurance, use of electronic media, higher household wealth quintile, having healthcare autonomy, showed a positive effect on taking screening services. Further analyses revealed that the strength of the associations varied considerably between urban and rural residents, denoting the need for region-specific intervention strategies. Sex of household head, age, watching TV, using radio, and having health insurance were the most significant contributors to the outcome effects. Conclusions The present study provides important insights regarding the current scenario of seeking cancer screening services among women in India. These findings could inform policy analysis and make an avenue for further in-depth analysis for future studies. Our findings conclude that cancer prevention policies should focus on leveraging the positive effects of better socioeconomic status, employment, health insurance ownership, exposure to electronic media, and better healthcare autonomy to improve the cancer screening service uptake among Indian women.

Abstract
Different metabolic and hormonal disorders like type 2 diabetes mellitus (T2DM), obesity, and polycystic ovary syndrome (PCOS) have tangible socio-economic impact. Prevalence of these metabolic and hormonal disorders is steadily increasing among women. There are clinical evidences that these physiological conditions are related to the manifestation of different gynecological cancers and their poor prognosis. The relationship between metabolic and hormonal disorders with gynecological cancers is quite complex. The need for gene level association study is extremely important to find markers and predicting risk factors. In the current work, we have selected metabolic disorders like T2DM and obesity, hormonal disorder PCOS, and 4 different gynecological cancers like endometrial, uterine, cervical, and triple negative breast cancer (TNBC). The gene list was downloaded from DisGeNET database (v 6.0). The protein interaction network was constructed using HIPPIE (v 2.2) and shared proteins were identified. Molecular comorbidity index and Jaccard coefficient (degree of similarity) between the diseases were determined. Pathway enrichment analysis was done using ReactomePA and significant modules (clusters in a network) of the constructed network was analyzed by MCODE plugin of Cytoscape. The comorbid conditions like PCOS-obesity found to increase the risk factor of ovarian and triple negative breast cancers whereas PCOS alone has highest contribution to the endometrial cancer. Different gynecological cancers were found to be differentially related to the metabolic/hormonal disorders and comorbid condition.

Abstract
Based on epidemiology studies, Chlamydia trachomatis has been proposed as a co-factor for human papillomavirus (HPV) in the development of cervical cancer. These two intracellular pathogens have been independently reported to induce the production of extra centrosomes, or centrosome amplification, which is a hallmark of cancer cells. We developed a cell culture model to systematically measure the individual and combined effects of Chlamydia and HPV on the centrosome in the same host cell. We found that C. trachomatis caused centrosome amplification in a greater proportion of cells than HPV and that the effects of the two pathogens on the centrosome were additive. Furthermore, centrosome amplification induced by Chlamydia, but not by HPV, strongly correlated with multinucleation and required progression through mitosis. Our results suggest that C. trachomatis and HPV induce centrosome amplification through different mechanisms, with the chlamydial effect being largely due to a failure in cytokinesis that also results in multinucleation. Our findings provide support for C. trachomatis as a co-factor for HPV in carcinogenesis and offer mechanistic insights into how two infectious agents may cooperate to promote cancer. TAKE AWAYS: • Chlamydia and HPV induce centrosome amplification in an additive manner. • Chlamydia-induced centrosome amplification is linked to host cell multinucleation. • Chlamydia-induced centrosome amplification requires cell cycle progression. • Chlamydia and HPV cause centrosome amplification through different mechanisms. • This study supports Chlamydia as a co-factor for HPV in carcinogenesis.

Abstract
OBJECTIVE We systematically investigated the prevalence of HPV, high-risk HPV and its genotypes in women living with human immunodeficiency virus (WLHIV) in Brazil. METHODS A systematic search was performed up to 15 December 2020. We included studies that used molecular methods for HPV detection in cervical samples and reported the prevalence of HPV in Brazilian WLHIV. The pooled prevalence of HPV, high-risk HPV (HR HPV) and HPV types and their 95% confidence interval (CI) were estimated. Subgroup analyses and meta-regression were conducted. RESULTS Thity-seven studies accounting for 8,436 WLHIV were included. The pooled HPV prevalence was 62% (95%CI 55-68%; I2 = 96.98%; P < 0.001). Prevalence of high-risk HPV was 40% (95%CI, 54-68%; I2 = 94.23%; P < 0.001). We found a wide variety of high-risk HPV genotypes. The high-risk HPV types most reported were HPV 16 (16%) and HPV 58 (6%). We found an increasing ratio of positivity from normal cervix to cancer. There were different factors associated with high-risk HPV, with low CD4+ count the most frequent. CONCLUSION The increase in the ratio of high-risk HPV positivity from normal cervix to carcinogenic lesions highlights the need to implement well-established testing for high-risk HPV in this population.

The interplay between the vaginal microbiome and innate immunity in the focus of predictive, preventive, and personalized medical approach to combat HPV-induced cervical cancer. EPMA J 2021; 12:199-220. [PMID: 34194585 PMCID: PMC8192654 DOI: 10.1007/s13167-021-00244-3] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2021] [Accepted: 05/04/2021] [Indexed: 12/20/2022]
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
Our study aimed to develop and validate a reliable instrument that can measure the quality of life (QOL) of patients with cervical cancer living in a developing country, such as the Central Balkan country, Serbia. Our study was cross-sectional for assessing the reliability and validity of a questionnaire. Balkan questionnaire for QOL of patients with cervical cancer showed satisfactory reliability and temporal stability. When the investigators rated the questionnaire, Cronbach's alpha was 0.971 at the beginning, and one month later it was 0.967. When the questionnaire was rated by patients themselves, Cronbach's alpha was 0.972. The questionnaire should be considered as an addition to the existing armamentarium for measuring the quality of life in patients with cervical cancer.

Abstract
Introduction: Cancer of the cervix has a progressive character and is one of the most significant public health problems in many countries. Our research aimed to translate EORTC QLQ CX 24 (European Organization for Research and Treatment of Cancer; Quality of life questionnaire-cervical cancer 24) from English to Serbian, to create essential cultural adaptations and to analyze psychometric properties of the translation in a model of female inpatients with cancer of the cervix. Method: The QLQ CX 24 was translated and adapted according to internationally established guidelines, and then tested on a sample of 100 Serbian females with cancer of the cervix. The testing was repeated three times on the same patients. We calculated the internal consistency (Cronbach’s alpha), criterion validity, convergent validity, and discriminative validity of the QLQ CX 24. We used factor analysis to discover the original construct. Results: The Serbian translation of QLQ CX 24 showed good internal consistency, showed satisfactory reliability, and temporal stability. In the first, when was rated by the investigators Cronbach’s alpha was 0.607, and one month later when the questionnaire also was rated by investigators Cronbach’s alpha was 0.696. When the scale was rated by females themselves Cronbach’s alpha was 0.802. Divergent as well as convergent validity tests had good results. The factorial analysis exposed six domains.Conclusion: The Serbian translation of QLQ CX 24 is a trustworthy and appropriate specific instrument for measuring the quality of life in females with cervical cancer.

Abstract
Background: Electronic cigarettes (e-cigarettes) generally have a more favorable toxicant profile than conventional cigarettes; however, limited information exists for women of reproductive age (WRA). Our aim was to compare biomarkers of toxicant exposure, inflammation, and oxidative stress among WRA who self-report exclusive e-cigarette use, exclusive cigarette smoking, or never tobacco use (controls). Methods: Multivariable linear regression models were used to compare the geometric means of urinary biomarkers of toxicant exposure and their metabolites, serum markers of inflammation [highly sensitive C-reactive protein, soluble intercellular adhesion molecule (sICAM), interleukin 6, fibrinogen], and a measurement of oxidative stress [prostaglandin F2a-8-isoprostane (F2PG2a)] among WRA from the Population Assessment of Tobacco and Health survey. Results: E-cigarette users had higher levels of lead, tobacco-specific nitrosamines, nicotine metabolites, and some volatile organic compounds (VOCs) than controls. Except for cadmium and lead, e-cigarette users had lower levels of the analyzed urinary toxicant biomarkers compared with cigarette smokers. Cigarette smokers had higher levels of all the biomarkers of toxicant exposure than controls. There were no significant differences in the levels of markers of inflammation and oxidative stress between e-cigarette users and controls. E-cigarette users and controls had lower levels of sICAM and F2PG2a than cigarette smokers. Conclusion: WRA who use e-cigarettes had lower levels of some of the evaluated urinary biomarkers of toxicant exposure and serum biomarkers of inflammation and oxidative stress than those who smoke cigarettes, but higher lead, nicotine metabolites, and some VOCs than controls, which can increase health risks.

Abstract
Cervical cancer (CC) is usually initiated by infection with high‐risk types of human papillomavirus (HPV). The HPV E6 and E7 proteins target p53 and RB, respectively, but other cellular targets likely exist. We generated uterus‐specific MOB1A/B double KO (uMob1DKO) mice, which immediately developed cervical squamous cell carcinoma in situ. Mutant cervical epithelial cells showed YAP1‐dependent hyperproliferation, altered self‐renewal, impaired contact inhibition, and chromosomal instability. p53 activation was increased in uMob1DKO cells, and additional p53 loss in uMob1DKO mice accelerated tumor invasion. In human CC, strong YAP1 activation was observed from the precancerous stage. Human cells overexpressing HPV16 E6/E7 showed inactivation of not only p53 and RB but also PTPN14, boosting YAP1 activation. Estrogen, cigarette smoke condensate, and PI3K hyperactivation all increased YAP1 activity in human cervical epithelial cells, and PTPN14 depletion along with PI3K activation or estrogen treatment further enhanced YAP1. Thus, immediate CC onset may initiate when YAP1 activity exceeds an oncogenic threshold, making Hippo‐YAP1 signaling a major CC driver.

Abstract
BACKGROUND Self-sampling for HPV testing, as an alternative to the conventional speculum based sampling, is highly acceptable to women of screening ages. The aim of this study was to describe older women's (60 to 75 years) experiences of self-sampling. METHODS In Sweden a descriptive study with quantitative and qualitative methods was designed to collect data from a survey of women who participated in self-sampling for HPV testing. Individual interviews were done with women who tested positive in the first self-sampling, and were either negative in their second HPV test or were positive in their second HPV test, but without precancerous lesions or cancer. RESULTS Of 893 eligible women, 868 (97.2%) answered the survey. Among the surveyed women, 49.2% reported it was very easy to perform self-sampling, 46.8% answered it was easy and 2.0% answered it was not easy. A majority (58.9%) answered that they prefer self-sampling, 16.5% that they prefer sample collection by a healthcare provider, 23.7% did not have any preference and 0.9% did not answer the question. In the interviews, 13 of 16 invited women participated. Most of them reported that they prefer self-sampling because it was easy to perform, less embarrassing and less time consuming than a visit to a clinic. The majority of women reported that they were not worried when informed about having an HPV positive test. Overall, participating women with better knowledge about the significance of an HPV infection were more worried about having a positive HPV test. CONCLUSION Cervical cancer remains a highly preventable disease through screening and early treatment. Our results indicated that vaginal self-sampling for HPV testing was a well-accepted method for cervical cancer prevention in this group of older women.

Abstract
Background Since the end of the previous century, there has not been a comprehensive review of European studies on socioeconomic inequality in cancer incidence. In view of recent advances in data source linkage and analytical methods, we aimed to update the knowledge base on associations between location-specific cancer incidence and individual or area-level measures of socio-economic status (SES) among European adults. Materials and methods We systematically searched three databases (PubMed, Scopus and Web of Science) for articles on cancer incidence and SES. Qualitative synthesis was performed on the 91 included English language studies, published between 2000 and 2019 in Europe, which focused on adults, relied on cancer registry data and reported on relative risk (RR) estimates. Results Adults with low SES have increased risk of head and neck, oesophagogastric, liver and gallbladder, pancreatic, lung, kidney, bladder, penile and cervical cancers (highest RRs for lung, head and neck, stomach and cervix). Conversely, high SES is linked with increased risk of thyroid, breast, prostate and skin cancers. Central nervous system and haematological cancers are not associated with SES. The positive gap in testicular cancer has narrowed, while colorectal cancer shows a varying pattern in different countries. Negative associations are generally stronger for men compared to women. Conclusions In Europe, cancers in almost all common locations are associated with SES and the inequalities can be explained to a varying degree by known life-style related factors, most notably smoking. Independent effects of many individual and area SES measures which capture different aspects of SES can also be observed.

Abstract
PURPOSE This study examined targeted genomic variants of transforming growth factor beta (TGFB) signaling in Appalachian women. Appalachian women with cervical cancer were compared to healthy Appalachian counterparts to determine whether these polymorphic alleles were over-represented within this high-risk cancer population, and whether lifestyle or environmental factors modified the aggregate genetic risk in these Appalachian women. METHODS Appalachian women's survey data and blood samples from the Community Awareness, Resources, and Education (CARE) CARE I and CARE II studies (n = 163 invasive cervical cancer cases, 842 controls) were used to assess gene-environment interactions and cancer risk. Polymorphic allele frequencies and socio-behavioral demographic measurements were compared using t tests and χ2 tests. Multivariable logistic regression was used to evaluate interaction effects between genomic variance and demographic, behavioral, and environmental characteristics. RESULTS Several alleles demonstrated significant interaction with smoking (TP53 rs1042522, TGFB1 rs1800469), alcohol consumption (NQO1 rs1800566), and sexual intercourse before the age of 18 (TGFBR1 rs11466445, TGFBR1 rs7034462, TGFBR1 rs11568785). Interestingly, we noted a significant interaction between "Appalachian self-identity" variables and NQO1 rs1800566. Multivariable logistic regression of cancer status in an over-dominant TGFB1 rs1800469/TGFBR1 rs11568785 model demonstrated a 3.03-fold reduction in cervical cancer odds. Similar decreased odds (2.78-fold) were observed in an over-dominant TGFB1 rs1800469/TGFBR1 rs7034462 model in subjects who had no sexual intercourse before age 18. CONCLUSIONS This study reports novel associations between common low-penetrance alleles in the TGFB signaling cascade and modified risk of cervical cancer in Appalachian women. Furthermore, our unexpected findings associating Appalachian identity and NQO1 rs1800566 suggests that the complex environmental exposures that contribute to Appalachian self-identity in Appalachian cervical cancer patients represent an emerging avenue of scientific exploration.

Abstract
IntroductionSince the implementation of human papillomavirus (HPV)-based screening for cervical cancer, the majority of cervical intra-epithelial neoplasia grade 2 (CIN2) lesions are high-risk (hr)HPV positive. Evidence on prognostic factors in hrHPV-positive CIN2 is lacking, hampering the individual counseling of women undergoing observation as routine management. The aim of this study is to identify prognostic factors for the spontaneous regression of hrHPV-positive CIN2.MethodsA retrospective cohort study was conducted at the Maastricht University Medical Center, the Netherlands. Women with hrHPV-positive CIN2 who underwent observation between January 1, 2000 and April 30, 2013 were included. Regression was defined as Pap 1/2 cytology (normal or atypical squamous cells of undetermined significance (ASCUS) cytology) or ≤CIN1 histology at the 24 month follow-up and no diagnosis of ≥CIN2 before the 24 month follow-up visit. Potential prognostic factors (HPV-16/18, p16 staining, KI67 staining, age, smoking status, last Pap smear result, multiple CIN2 lesions, oral contraception use, and parity) were assessed using logistic regression analysis.ResultsA total of 56 women were included in the study, of which 34 (61%) showed spontaneous regression of their lesion. Of all studied potential prognostic factors, only not smoking and nulliparity were significantly associated with disease regression (OR 3.84, 95% CI 1.04 to 14.21, and OR 5.00, 95% CI 1.32 to 19.00, respectively, in the univariate analysis). Both effects remained significant after correction for age and HPV-16/18 in a multivariable regression analysis. In women who smoked, disease regression occurred in 10 of 22 women (46%), compared with 16 of 21 women (76%) who did not smoke. In parous women, regression occurred in 12 of 27 women (44%), compared with 16 of 20 nulliparous women (80%).DiscussionSmoking status and parity may influence the likelihood of disease regression in hrHPV-positive CIN2. These factors could be considered in individual patient counseling regarding the choice between immediate treatment or conservative management.

Abstract
Introduction The aim of this qualitative study was to describe the motivation and experiences of women with cervical dysplasia and associated diagnoses who used electronic cigarettes (ECs) to reduce the number of cigarettes they smoked. Methods Qualitative interviews were conducted with 26 women aged 18‐65 years with cervical dysplasia and associated diagnoses who smoked at least three cigarettes daily for the past year or more and who enrolled in an intervention designed to substitute regular cigarettes with ECs. At the 12‐week follow‐up, patients were contacted by telephone. Semi‐structured interviews were recorded, then transcribed, coded and analysed for themes. Results When confronted with a new diagnosis associated with smoking, women in this study were eager to try ECs to help them reduce their intake of cigarettes. Women reported that physical cues similar to smoking, delivery of nicotine sufficient to assist with smoking reduction and the security of having the device available to use in instances where temptations to smoke may occur were all positive experiences in trying the device. Other women in the study reported negative experiences, such as a lack of sufficient nicotine to eliminate cravings, heaviness of the device and the need to keep it charged. Depression, nicotine addiction and habit were factors that made it difficult to decrease cigarette consumption. Conclusions Findings suggest that ECs may help with smoking substitution in patients who must reduce smoking due to medical conditions or diagnoses.

Abstract
High-risk human papillomavirus (HR-HPV) infection is not a sufficient condition for cervical cancer development because most infections are benign and naturally cleared. Epidemiological studies revealed that tobacco smoking is a cofactor with HR-HPV for cervical cancer initiation and progression, even though the mechanism by which tobacco smoke cooperates with HR-HPV in this malignancy is poorly understood. As HR-HPV E6/E7 oncoproteins overexpressed in cervical carcinomas colocalize with cigarette smoke components (CSC), in this study we addressed the signaling pathways involved in a potential interaction between both carcinogenic agents. Cervical cancer-derived cell lines, CaSki (HPV16; 500 copies per cell) and SiHa (HPV16; 2 copies per cell), were acutely exposed to CSC at various non-toxic concentrations and we found that E6 and E7 levels were significantly increased in a dose-dependent manner. Using a reporter construct containing the luciferase gene under the control of the full HPV16 long control region (LCR), we also found that p97 promoter activity is dependent on CSC. Non-synonymous mutations in the LCR-resident TPA (12-O-tetradecanoylphorbol 13-acetate)-response elements (TRE) had significantly decreased p97 promoter activation. Phosphoproteomic arrays and specific inhibitors revealed that CSC-mediated E6/E7 overexpression is at least in part reliant on EGFR phosphorylation. In addition, we showed that the PI3K/Akt pathway is crucial for CSC-induced E6/E7 overexpression. Finally, we demonstrated that HPV16 E6/E7 overexpression is mediated by JUN. overexpression, c-Jun phosphorylation and recruitment of this transcription factor to TRE sites in the HPV16 LCR. We conclude that acute exposure to tobacco smoke activates the transcription of HPV16 E6 and E7 oncogenes through p97 promoter activation, which involves the EGFR/PI3K/Akt/C-Jun signaling pathway activation in cervical cancer cells.

Abstract
High risk human papillomavirus (HPV) infections are the causative agent in virtually every cervical cancer as well as a host of other anogenital and oropharyngeal malignancies. These viruses must activate DNA repair pathways to facilitate their replication, while avoiding the cell cycle arrest and apoptosis that can accompany DNA damage. HPV oncoproteins facilitate each of these goals, but also reduce genome stability. Our data dissect the cytotoxic and cytoprotective characteristics of HPV oncogenes in cervical cancer cells. These data show that while the transformation of keratinocytes by HPV oncogene leaves these cells more sensitive to UV, the oncogenes also protect against UV-induced apoptosis. Cisplatin and UV resistant cervical cancer cell lines were generated and probed for their sensitivity to genotoxic agents. Cervical cancer cells can acquire resistance to one DNA crosslinking agent (UV or cisplatin) without gaining broad tolerance of crosslinked DNA. Further, cisplatin resistance may or may not result in sensitivity to PARP1 inhibition.

Abstract
BACKGROUND The risk of a second primary cancer has increased along with the increasing life expectancies of colorectal cancer survivors. OBJECTIVE We aimed to evaluate the incidence rate and risk factors of breast and gynecological (ovarian, uterine cervix/corpus) cancers among female colorectal cancer survivors. DESIGN This is a retrospective population-based cohort study. SETTINGS This study used data from the National Health Insurance Corporation of Korea. PATIENTS Each patient with colorectal cancer diagnosed from 2007 to 2012 was followed until 2015 and compared with age-matched women without colorectal cancer at a 1:5 ratio. MAIN OUTCOME MEASURES The primary outcome was de novo breast/gynecological cancer. Patients with available medical checkup data were included in an additional analysis. RESULTS We analyzed 56,682 patients with colorectal cancer and 288,119 age-matched noncolorectal cancer controls. The risk of breast/gynecological cancer was higher among patients with colorectal cancer than among controls (HR, 2.91; p < 0.001). The association with colorectal cancer was the highest for ovarian cancer (HR, 6.72), followed by uterine corpus cancer (HR, 3.99), cervical cancer (HR, 2.82), and breast cancer (HR, 1.85). This association remained consistent in the subgroup analysis of medical checkup data (14,190 patients with colorectal cancer, 71,933 controls). Among patients with colorectal cancer, those aged <55 years had a higher risk of breast/gynecological cancers than those aged >55 years (HR, 3.51 vs 2.59), and those with dyslipidemia had a higher risk of breast cancer than those without dyslipidemia (HR, 2.66 vs 2.06). LIMITATIONS This was a retrospective, population-based study. A prospectively designed study is needed to validate our conclusions. CONCLUSIONS Compared with the general population, patients with colorectal cancer carry a higher risk of developing secondary breast, ovarian, and uterine cancers.

Disparities in human papillomavirus-related cancer incidence and survival among human immunodeficiency virus-infected Hispanics living in the United States. Cancer 2018; 124:4520-4528. [PMID: 30345506 DOI: 10.1002/cncr.31702] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2018] [Revised: 07/02/2018] [Accepted: 07/04/2018] [Indexed: 01/06/2023]
Abstract
BACKGROUND Human papillomavirus (HPV) causes 10% of cancers among human immunodeficiency virus (HIV)-infected people in the United States. Because Hispanics are disproportionally affected by the HIV epidemic and by infection-related cancers, this study compared incidence rates for HPV-related cancers and survival between Hispanics and non-Hispanic whites (NHWs) and non-Hispanic blacks (NHBs) in the HIV-infected US population. METHODS Based on data from the HIV/AIDS Cancer Match Study, standardized incidence ratios (SIRs) were used to estimate cancer risk in HIV-infected Hispanics and the general US Hispanic population. Among HIV-infected people, cancer rates were compared with incidence rate ratios (IRRs), and survival was compared with hazard ratios between Hispanics and NHWs and NHBs. RESULTS Five hundred two HPV-related cancers occurred in 864,067 person-years of follow-up among HIV-infected Hispanics. Except for oropharyngeal cancer, the risk of HPV-related cancers was higher among HIV-infected Hispanics than in the general population (SIR range, 3.59 [cervical cancer] to 18.7 [anal cancer in men]). Among HIV-infected females, Hispanics had higher cervical cancer rates than NHWs (IRR, 1.70; 95% confidence interval [CI], 1.19-2.43) but lower vulvar cancer rates than NHWs (IRR, 0.40; 95% CI, 0.24-0.67) and NHBs (IRR, 0.62; 95% CI, 0.41-0.95). Among HIV-infected males, Hispanics had higher penile cancer rates than NHWs (IRR, 2.60; 95% CI, 1.36-4.96) but lower anal cancer rates than NHWs (IRR, 0.54; 95% CI, 0.46-0.63) and NHBs (IRR, 0.65; 95% CI, 0.56-0.77). Among HIV-infected Hispanics, 5-year survival was greater than 50% across HPV-related cancer types, with no major differences by racial/ethnic group. CONCLUSIONS HIV-infected Hispanics have an elevated risk for HPV-related cancers. Similarly to the general population, HIV-infected Hispanics have higher rates of cervical and penile cancer than NHWs and NHBs. HPV vaccination should be promoted among HIV-infected individuals to reduce the burden of HPV-related cancers.

Abstract
Objective: Association of multiple polymorphic variants with cervical cancer has been elucidated by several
candidate gene based as well as genome-wide association studies. However, contradictory outcomes of those studies
have failed to estimate the true effect of the polymorphic variants on cervical cancer. Methods: Literature mining of
the PubMed database was done to gather all the publications related to genetic association with cervical cancer in India.
Out of 98 PubMed hits only 29 genetic association studies were selected for meta-analysis based on specific inclusion
criteria. A fixed-effect meta-analysis was performed to evaluate the overall association of the genetic polymorphisms
with cervical cancer. Cochran’s Q test was performed to assess between study heterogeneity. Publication bias was
also estimated by funnel plots and Egger’s regression test. Further, sub-group analysis was conducted by fixed-effect
meta-regression to assess the impact of polymorphisms on cervical cancer in the presence of Human Papilloma Virus
(HPV). Result: Following a fixed-effect model, meta-analysis was conducted that revealed 2 polymorphic variants
viz. ‘deletion polymorphism (Del2) (OR=1.79, 95% CI= 1.08-2.95, P=0.023) in GSTM1’ and ‘rs1048943 (OR = 2.34,
95% CI=1.37-3.99, P=0.0018) in CYP1A1’ to be associated with cervical cancer. However, multiple testing correction
showed only rs1048943 of CYP1A1 to be significantly associated (P-value=0.029) with cervical cancer with significant
publication bias (P-value=0.0113) as estimated by Egger’s regression test. The polymorphic variants ‘rs1801131’,
‘rs1801133’, ‘rs2430561’, ‘rs1799782’, ‘rs25486’ and ‘rs25487’ showed significant (p<0.05) evidence of heterogeneity
between studies by Cochran’s Q test and also by heterogeneity index (I2) calculation. Conclusion: Therefore, our study
revealed significant association of rs1048943 in CYP1A1, but a nominal association of deletion polymorphism (Del2)
in GSTM1 with cervical cancer, which provides a comprehensive insight on the true effect of the polymorphisms,
reported in various case-control studies, on the risk of the development of cervical cancer in Indian women.

Abstract
CONTEXT AND OBJECTIVE Incarcerated women are more vulnerable to developing cervical cancer than women in general; therefore, screening and intervention programs must be included in their healthcare provision. We therefore aimed to investigate the state of cervical cancer screening for imprisoned women in Mato Grosso do Sul, and to analyze the interventions geared toward the control of cervical cancer. MATERIALS AND METHODS This was a cross-sectional study with analysis of primary and secondary data. Interviews were held with 510 women in seven prisons in the Brazilian state of Mato Grosso do Sul. The data for 352 medical records were analyzed statistically with the significance level set at 5%. Associations were assessed by the chi-squared test, adjusted by the Bonferroni correction. RESULTS Most female prisoners had limited education, used tobacco, and had key risk factors for the development of cervical cancer. Half of the women interviewed (n = 255) stated that they had received a Papanicolaou (Pap) test in prison, but 134 (52.5%) of these did not know the result. Of those who had not received a Pap test, 149 (58.4%) stated that this was because of a lack of opportunity. There was no information regarding the provision of Pap tests or subsequent treatment in the medical records of 211 (59.9%) women. No protocols were in place for the provision of Pap tests in prison. There were statistical differences between prisons in terms of test frequency, the information provided to women, and how information was recorded in medical records. CONCLUSION The screening of cervical cancer in prisons is neither systematic nor regular, and the results are not communicated to women in a significant number of cases. It is necessary to organize health services within the prison environment, ensuring that tests are done and that there is investigation for human papillomavirus. This could increase the diagnosis of cervical cancer at less advanced stages of the disease.

Abstract
Human papillomavirus (HPV) was found to be the causative agent for cervical cancer in the 1980s with almost 100% of cervical cancer cases testing positive for HPV. Since then, many studies have been conducted to elucidate the molecular basis of HPV, the mechanisms of carcinogenesis of the virus, and the risk factors for HPV infection. Traditionally, the Papanicolaou test was the primary screening method for cervical cancer. Because of the discovery and evolving understanding of the role of HPV in cervical dysplasia, HPV testing has been recommended as a new method for cervical cancer screening by major professional organizations including the American Cancer Society, American Society for Colposcopy and Cervical Pathology, and the American Society for Clinical Pathology. In order to detect HPV infections, many sensitive and specific HPV assays have been developed and used clinically. Different HPV assays with various principles have shown their unique advantages and limitations. In response to a clear causative relationship between high-risk HPV and cervical cancer, HPV vaccines have been developed which utilize virus-like particles to create an antibody response for the prevention of HPV infection. The vaccines have been shown in long-term follow-up studies to be effective for up to 8 years; however, how this may impact screening for vaccinated women remains uncertain. In this chapter, we will review the molecular basis of HPV, its pathogenesis, and the epidemiology of HPV infection and associated cervical cancer, discuss the methods of currently available HPV testing assays as well as recent guidelines for HPV screening, and introduce HPV vaccines as well as their impact on cervical cancer screening and treatments.

Abstract
BACKGROUND The incidence of human papillomavirus (HPV)‐associated (HPV‐positive) head and neck squamous cell carcinoma (HNSCC) of the oropharynx has dramatically increased over the last decade and continues to rise. Newly diagnosed HPV‐positive HNSCCs in the United States currently outnumber any other HPV‐associated cancers, including cervical cancer. Despite introduction of the HPV vaccine, the epidemic of HPV‐positive HNSCC is expected to continue for approximately 60 years. Compared with patients who have tobacco‐associated HNSCC, those who have HPV‐positive HNSCC have better overall survival and response to treatment. Current treatment, including chemotherapy and radiation therapy, is associated with lifelong morbidity, and there are limited treatments and no curative options for patients who develop recurrent metastatic disease. Therapeutic de‐escalation (decreased radiation dose) is being tested through clinical trials; however, those studies select patients based solely on tumor and patient smoking characteristics. Mechanisms of HPV‐driven carcinogenesis in HNSCC are not well understood, which limits new therapeutic strategies and hinders the appropriate selection of patients for de‐escalation therapy. METHODS The authors analyzed HNSCC data from The Cancer Genome Atlas to identify molecular characteristics that correlate with outcomes and integration status of the HPV genome. RESULTS The current investigations identified a subset of HPV‐positive HNSCCs with mutations in the genes TRAF3 (tumor necrosis factor receptor‐associated factor 3) and CYLD (cylindromatosis lysine 63 deubiquitinase). Defects in TRAF3 and CYLD correlated with the activation of transcriptional factor nuclear factor κB, episomal HPV status of tumors, and improved patient survival. CONCLUSIONS Defects in TRAF3/CYLD were accompanied with the activation of nuclear factor κB signaling and maintenance of episomal HPV in tumors, suggesting that these mutations may support an alternative mechanism of HPV tumorigenesis in head and neck tumors.

Human papillomavirus‐associated head and neck cancer tends to respond better to treatment compared with tobacco‐associated tumors; however, patients suffer severe and long‐lasting side effects. Somatic mutations in the genes TRAF3 and CYLD identified in The Cancer Genome Atlas data set are correlated with the activation of nuclear factor‐κB, define a distinct etiologic subset of head and neck cancers, and will be useful as biomarkers for predicting improved prognosis and selecting patients with human papillomavirus‐positive head and neck cancer who may be successfully treated with de‐escalating therapy.

Abstract
Abstract
Aim: The present study aim to analyze the relationship between GST M/T genotypes of glutathione S-transferases and cervical intraepithelial neoplasia.
Materials and Methods: A prospective case-control study has been designed including 69 cases with different degrees of cervical dysplasia and 107 controls. All patients had been examined colposcopically. For every patient both cervical and blood specimen have been obtained. The peripheral blood was used for GST M/T genotyping. The statistical analysis was performed using OR and chi-square at a level of significance inferior to 0.05.
Results: No statistically significant differences had been found between cases and controls for GST T-/M- geno-type (T-/M-, χ2=0.03, p= 0.8610) and T+/M+ χ2=0.65, p = 0.4197. Patients with in situ carcinoma had significant GST genotype association for T-/M+ genotype (OR=4.66, CI 95% [0.6528,24.9725], χ2=4.6, p=0.0314) and for T+/M- genotype (OR=0.12, CI 95% [0.0027,0.9465], χ2=0.05, p=0.0219).
Conclusion: The combination of GST genotypes can be included in a predictive score for patients with cervical carcinoma.

Abstract
Many women know about the risks of lung cancer and cardiovascular disease that stem from tobacco use, but many don't realize there are several other potential health consequences of smoking. Nurses should utilize every opportunity to educate women about the various health risks of smoking. Promotion of smoking cessation now may help women prevent numeroushealth problems later.

[PMID: 26864126 PMCID: PMC4964724 DOI: 10.1080/21645515.2016.1141158] [Citation(s) in RCA: 53] [Impact Index Per Article: 6.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2015] [Revised: 12/21/2015] [Accepted: 01/07/2016] [Indexed: 10/24/2022] Open
Abstract
There has been some concern among parents and in the media that vaccinating children against human papillomavirus could be seen as giving children permission to engage in risky sexual behaviors (also known as sexual disinhibition). Several studies have found this concern to be unfounded but there have been no attempts to synthesize the relevant studies in order to assess if there is evidence of sexual disinhibition. The aim of this study was to synthesize recent literature examining sexual behaviors and biological outcomes (e.g., sexually transmitted infections) post-HPV vaccination. We reviewed literature from January 1, 2008-June 30, 2015 using PubMed, CINAHL, and Embase with the following search terms: [(sex behavior OR sex behavior OR sexual) AND (human papillomavirus OR HPV) AND (vaccines OR vaccine OR vaccination)] followed by a cited reference search. We included studies that examined biological outcomes and reported behaviors post-vaccination in both males and females. Studies were reviewed by title and abstract and relevant studies were examined as full-text articles. We identified 2,503 articles and 20 were eventually included in the review. None of the studies of sexual behaviors and/or biological outcomes found evidence of riskier behaviors or higher rates of STIs after HPV vaccination. Instead, the studies found that vaccinated compared to unvaccinated individuals were less likely to report vaginal intercourse without a condom (OR = 0.5; 95%CI = 0.4-0.6) and non-use of contraception (OR = 0.27; 95%CI = 0.15-0.48) and unvaccinated participants had higher rates of Chlamydia (OR = 2.3; 95%CI = 1.06-5.00). These results should be reassuring to parents and health care providers.

Sociodemographic characteristics and sexual behavior as risk factors for human papillomavirus infection in Saudi Arabia. Int J Infect Dis 2016; 46:94-9. [PMID: 27062984 DOI: 10.1016/j.ijid.2016.04.004] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/24/2015] [Revised: 03/31/2016] [Accepted: 04/03/2016] [Indexed: 12/01/2022] Open
Abstract
OBJECTIVES To determine the prevalence and the sociodemographic characteristics and sexual behavior risk factors for human papillomavirus (HPV) infection in a hospital-based cohort of women in Saudi Arabia. METHODS Cervical specimens and questionnaire data were collected from women attending clinics in Riyadh, Saudi Arabia. Cervical specimens were examined for abnormal cytology using a standard Pap test and for the presence of HPV-DNA using PCR and reverse line blot hybridization tests. RESULTS Approximately 73% of the 400 women tested were Saudi nationals. Nearly 50% were under 40 years old (range 22-80 years, mean±standard deviation 41.20±10.43 years). Approximately 17% of the women were HPV-positive. The most commonly detected HPV types were HPV-18 (34%) and HPV-16 (19%), with multiple infections detected in 10% of positive specimens. Multivariate analyses revealed that smoking and multiple partners were significant risk factors for HPV infection (p<0.01). CONCLUSIONS Because of societal challenges and an unsubstantiated assumption of low HPV prevalence, few studies have examined sociodemographic characteristics or sexual behaviors associated with HPV in Saudi women. However, a high prevalence of HPV infection was found, with smoking and multiple partners as significant risk factors, in this hospital-based cohort of predominantly Saudi women.
