Cancer Causes Control 2024; 35:549-559. [PMID: 37924461 DOI: 10.1007/s10552-023-01813-9] [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: 04/12/2023] [Accepted: 10/06/2023] [Indexed: 11/06/2023]
Abstract
BACKGROUND Cervical cancer is the second-leading cause of death among all cancers in Ethiopia. Ethiopia plans to eliminate cervical cancer as a public health problem by 2030, following the World Health Organization's call for action. A scoping review was conducted on the status of the cervical cancer continuum towards elimination in Ethiopia. METHODS We searched articles in PubMed, Scopus, and Google Scholar. All studies conducted on cervical cancer in Ethiopia, from first date of publication to March 15, 2023, type of article, or language of publication, were included. However, conference abstracts, commentaries, and letters to the editors were excluded. We used EndNote X9 software to merge articles from different databases and automatically remove duplicates. Screening of titles, abstracts, and full texts was performed independently by two co-authors. The cancer care continuum was employed as a framework to guide data synthesis and present the findings. RESULTS Of the 569 retrieved articles, 159 were included in the review. They found that most of the articles focused on knowledge, attitude, and practice. However, there were few studies on health-seeking behavior, perception and acceptability of cervical cancer services, as well as the availability and readiness of a screening program. The review identified inadequate knowledge, attitude, and perception about cervical cancer, and highlighted that screening for cervical cancer is not widely utilized in Ethiopia. Knowledge, attitude, education status, and income were repeatedly reported as precursors influencing cervical cancer screening. Most studies concluded that there is a high prevalence of precancerous lesions and cervical cancer, as well as high mortality rates or short survival times. The review also identified significant heterogeneity in findings across time and geographic settings within each component of the cancer care continuum. CONCLUSIONS Overall, there is inadequate knowledge, perception, health-seeking behavior, screening, and treatment services, indicating that the country is falling behind its targets in eliminating cervical cancer, despite the availability of effective interventions and tools. We argue that implementation research is necessary to identify implementation issues, challenges, and strategies to scale up both primary and secondary prevention services. By doing so, Ethiopia can address cervical cancer as a public health problem and work towards its elimination.

Prevalence of human papillomavirus infection and associated factors among women attending cervical cancer screening in setting of Addis Ababa, Ethiopia. Sci Rep 2024; 14:4053. [PMID: 38374354 PMCID: PMC10876560 DOI: 10.1038/s41598-024-54754-x] [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: 09/30/2023] [Accepted: 02/15/2024] [Indexed: 02/21/2024] Open
Abstract
Human papillomaviruses (HPVs) are circular, nonenveloped small double-stranded DNA viruses that infect stratified epithelium and can cause a number of life-threatening diseases. HPV is the central risk factor for developing cervical cancer and is estimated that approximately 98% of this disease is associated with oncogenic types of HPV. HPV infection leads to an estimated 266,000 cervical cancer deaths annually. Therefore, the objective of this study was to determine the prevalence of HPV infection and risk factors associated with cervical lesion among women attending the cervical cancer screening clinic at the Ethiopian Family Guidance Association, Addis Ababa. A cross-sectional study was conducted to determine the prevalence of HPV infection. Data were collected using a questionnaire and samples leftover from cervical screening were taken. The leftover swab was air dried and DNA was extracted and amplified by using a PCR. A total of 247 women were included in the study. The prevalence of HPV was 9.72% among the population studied. Of all participants, 27.13% were positive for cervical intraepithelial neoplasia-1 (CIN1). CIN1 positivity was found in half of HPV positive women. Among HPV positive women, half of them had started sexual intercourse at ages 12-17 years and 41.66% were women who gave birth at ages 12-17 years. The high prevalence of HPV and the CIN1 positive group were ages 36-57 and women with multiple sexual partners. The other groups with the highest CIN1 positive were 22.39% grade (9-12) and 20.9% primary (1-8) and uneducated women. Among HPV positive women, 83.33% had an abortion history and 80% miscarried in the first trimester. Among the CIN1 positives, 53.73% had more than two sexual partners. Among HPV positive women, half of them were users of contraception methods. In conclusion, the highest prevalence of HPV is among women who began sexual intercourse earlier and who gave birth at 12-17 years of age, have an abortion history, with MSP and oral contraceptive methods users. In addition to HPV, early pregnancy and sexual intercourse at 12-17 years of age, abortion, MSP, and oral hormonal contraceptives are factors in cervical cancer. Finally, most women do not have enough knowledge and awareness about cervical cancer and the risk factor.

Abstract
Background Cervical cancer is the most prevalent gynecologic cancer in women and the second leading cause of cancer death worldwide. Africa's southern, eastern, and western regions have the highest rates of cervical cancer. Cervical cancer is treatable and curable when detected early, but it is nonetheless fatal in low- and middle-income (LMIC) nations where screening and early detection are not widely accessible. Objective The objective of this study is to assess the magnitude of precancerous cervical lesions and their associated factor among women screened for cervical cancer at a referral center in southern Ethiopia, in 2021. Methods A retrospective institution-based cross-sectional study was conducted from February 21 to April 14, 2022, among randomly selected 372 records of women screened for cervical cancer at Hawassa University Specialized Hospital. Data were extracted from clients' charts using a data extraction checklist. Statistical Package for Social Sciences version 26 and logistic regression analysis were applied to determine the association between dependent and independent variables, and significance was declared at p-value <0.05. Results The magnitude of abnormal cervical dysplasia in this study was 18.3% of which 14% were precancerous cervical lesions and 4.3% were cervical cancer. Early coitarche: Adjusted odds ratio (AOR) = 5.6 [95% (confidence interval) CI = 1.87-16.78], having more than one sexual partner: AOR = 2.6 [95% CI = 1.2-5.68], being HIV positive: AOR = 3.56 [95% CI = 1.53-8.29], and having sexually transmitted infections: AOR = 4.64 [95% CI = 2.08-10.35] were independent predictors of precancerous cervical lesions. Conclusion The magnitude of precancerous cervical lesions in the study setting is 18% and the magnitude of cervical cancer is 14%, which is higher than the pooled prevalence of precancerous cervical lesions in Ethiopia. Having multiple sexual partners, being HIV positive, having sexual intercourse before 21 years, and new STI diagnosis was independently associated with abnormal precancerous cervical lesions.

Abstract
OBJECTIVE Persistent high-risk human papillomavirus (hrHPV) infection is associated with most cervical cancers. This study aims to investigate the prevalence of and independent risk factors for hrHPV infection among women residing in rural areas of Shanxi Province, China. METHODS Data from the records of the cervical cancer screening programs for rural women in Shanxi Province were retrospectively collected. Women receiving primary HPV screening between January 2014 and December 2019 were included. The detection rate of hrHPV was calculated, and the independent risk factors for hrHPV infection were analyzed by multivariate logistic regression. RESULTS Among the women included, the overall infection rate of hrHPV was 14.01% (15,605/111,353), with the top five subtypes being HPV16 (24.79%), HPV52 (14.04%), HPV58 (10.26%), HPV18 (7.25%), and HPV53 (5.00%). The independent risk factors for hrHPV infection were specific geographical regions, testing years, older age, lower education level, inadequate previous screening, bacterial vaginosis, trichomonas vaginitis, and cervical polyps. CONCLUSION Rural women over 40 years of age, especially those who had never received screening, have a significantly increased risk for hrHPV infection and should be the target population with priority in cervical cancer screening.

Abstract
Cervical cancer screening is a challenge mainly in developing countries. In developed countries, both incidence and mortality rates have been decreasing due to well organized screening programs. One of the potential biomarkers being exploited are the minichromosome maintenance proteins (MCMs), which show both specificity and sensitivity. MCM2-7 are involved in DNA replication initiation and elongation, and the MCM subunits are highly expressed in malignant tissues. Unlike other MCMs, MCM10, which is not part of the core helicase complex, is a critical determinant of origin activation and its levels are limiting in cancer cells. In this study, we performed bioinformatic analysis on the expression profile of all DNA replication associated MCM proteins in cervical cancer. MCM10 showed a relatively higher expression profile compared to the other MCMs. The mRNA expression levels of the MCMs were significantly increased in tumour tissues compared to normal, and MCM10 showed a fold change of 3.4. In order to understand if MCM10 is associated with the aggressiveness of cervical cancer, we looked into the mRNA expression pattern of MCM10 in three cervical cancer cell lines and one normal cervical cell line. MCM10 expression was significantly higher in the case of the more aggressive cancer cell line HeLa compared to controls. MCM10, therefore, can serve as a prominent biomarker for cancer progression and thus aid in early detection to control the spread of cancer cells. Our results show that MCM10 expression levels in cervical cancer cell lines are associated with cancer aggressiveness, demonstrating its clinical significance.

Abstract
Cervical carcinoma (CC) is the fourth most common malignancy among women. Screening with Papanicolau smear is linked to a reduction in CC incidence rates when screening programs have been developed. However, this technique has several limitations, including moderate sensitivity rates for detection of cervical preneoplastic HPV-related lesions. In this real-world study, we proposed to evaluate the sensitivity and specificity rates of cobas® test, which amplifies target DNA fragments by polymerase chain reaction and hybridization of nucleic acids for the detection of 14 HR-HPV types in a single analysis) used as primary screening test for CC and preneoplastic lesions in women aged 25-65 years in a large University Hospital in Buenos Aires. A total of 1044 patients were included in the sample (median age: 46 years); sensitivity and specificity rates for the HR-HPV test used as primary screening test were 98.66% (95% confidence interval [95CI]: 97.67-99.3%) and 87.15% (95CI: 84.93-89.15%), respectively. The positive predictive value was 88.47% (95CI: 86.54%-90.42%) and the negative predictive value was 98.48% (95CI: 97.75%-99.23%). The cobas® HR-HPV testing was highly sensitive and specific for the detection of CC and preneoplastic lesions in real practice.

Abstract
OBJECTIVE To determine the prevalence of HPV and investigate factors associated with the infection in women in the city of Francisco Beltrão, southwest Paraná, attending the public health system. METHODS This cross-sectional study included 324 women, aged between 18 and 65 years, who were attending public health services for routine gynecological consultation. Interviews were conducted to obtain information about socioeconomic, sexual, gynecological, and life habits. After performing the Papanicolaou test, endocervical brush was employed to detect HPV by polymerase chain reaction with the primers MY09-MY11. RESULTS The prevalence of HPV was 6.8%, out of which 58.3% presented with cytopathologic alterations. And the presence of current cervical alterations can increase the chances of having HPV by almost 33 times (ORadj: 32.688; p < 0.001), recent vaginal infection increased the chances of HPV infection by 2.7 times (ORadj: 2.773; p = 0.04). The non-white ethnicity increased HPV infection chances threefold (ORadj: 3.058; p = 0.039). CONCLUSION The main finding was low prevalence of HPV infection. Factors that may be linked to HPV infection were cervical alterations, recent vaginal infection, and women's ethnicity.

Gebrie A. Disease progression role as well as the diagnostic and prognostic value of microRNA-21 in patients with cervical cancer: A systematic review and meta-analysis. PLoS One 2022; 17:e0268480. [PMID: 35895593 PMCID: PMC9328569 DOI: 10.1371/journal.pone.0268480] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2022] [Accepted: 05/01/2022] [Indexed: 02/07/2023] Open
Abstract
Introduction Cervical cancer is the fourth commonest and the fourth leading cause of cancer death in females globally. The upregulated expression of microRNA-21 in cervical cancer has been investigated in numerous studies, yet given the inconsistency on some of the findings, a systematic review and meta-analysis is needed. Therefore, the aim of this systematic review and meta-analysis is to investigate the role in disease progression as well as the diagnostic and prognostic value of microRNA-21 in patients with cervical cancer. Methods Literature search was carried out through visiting several electronic databases including PubMed/MEDLINE/ PubMed Central, Web of Science, Embase, WorldCat, DOAJ, ScienceDirect, and Google Scholar. After extraction, data analysis was carried out using Rev-Man 5.3, STATA 15.0 and Meta-disk 1.4. I2 and meta-bias statistics assessed heterogeneity and publication bias of the included studies, respectively. The area under summary receiver operating characteristic curve and other diagnostic indexes were used to estimate diagnostic accuracy. Result A total of 53 studies were included for this systematic review and meta-analysis. This study summarized that microRNA-21 targets the expression of numerous genes that regulate their subsequent downstream signaling pathways which promote cervical carcinogenesis. The targets addressed in this study included TNF-α, CCL20, PTEN RasA1, TIMP3, PDCD-4, TPM-1, FASL, BTG-2, GAS-5, and VHL. In addition, the meta-analysis of reports from 6 eligible studies has demonstrated that the overall area under the curve (AUC) of summary receiver operating characteristic (SROC) of microRNA-21 as a diagnostic accuracy index for cervical cancer was 0.80 (95% CI: 0.75, 0.86). In addition, evidence from studies revealed that upregulated microRNA-21 led to worsening progression and poor prognosis in cervical cancer patients. Conclusion microRNA-21 is an oncogenic microRNA molecule playing a key role in the development and progression of cervical malignancy. It has good diagnostic accuracy in the diagnosis of cervical cancer. In addition, the upregulation of microRNA-21 could predict a worse outcome in terms of prognosis in cervical cancer patients.

HPV types 16/18 L1 E6 and E7 proteins seropositivity and cervical cancer risk in HIV-positive and HIV-negative black South African women. Infect Agent Cancer 2022; 17:14. [PMID: 35351184 PMCID: PMC8966297 DOI: 10.1186/s13027-022-00418-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2021] [Accepted: 02/11/2022] [Indexed: 11/24/2022] Open
Abstract
BACKGROUND In populations with high rates of human immunodeficiency virus (HIV)-coinfection, the nature of the relationship between human papillomavirus (HPV)-16 and -18 (L1, E6 and E7) antibodies and cervical cancer is still uncertain. We measured the association between seropositivity to HPV (L1, E6 and E7) proteins and cervical cancer among black South African women with and without HIV co-infection. METHODS We used questionnaire data and serum collected from consecutively recruited patients with a newly diagnosed cancer from the Johannesburg Cancer Study from 1346 cervical cancer cases and 2532 controls (diagnosed with other non-infection related cancers). Seropositivity to HPV proteins was measured using a multiplex serological assay based on recombinant glutathione S-transferase (GST) fusion proteins. We measured associations between their presence and cervical cancer using unconditional logistic regression models and evaluated the sensitivity and specificity of these HPV biomarkers. RESULTS Among controls, HIV-negative women from rural areas compared to urban had significantly higher HPV seroprevalence, HPV16 E7 (8.6% vs 3.7%) and HPV18 E7 (7.9% vs 2.0%). HPV16 E6 and E7 antibodies were positively associated with cervical cancer in HIV-positive (Adjusted Odds Ratio (AOR) = 33; 95% CI 10-107) and HIV-negative women (AOR = 97; 95% CI 46-203). In HIV-positive women, HPV E6/E7 antibodies had low sensitivity (43.0%) and high specificity (90.6%) for cervical cancer detection. In HIV-negative women, HPV E6/E7 antibodies sensitivity was 70.6% and specificity was 89.7%. CONCLUSIONS Our data show that HPV (L1, especially E6 and E7) antibody positivity is associated with cervical cancer in both HIV-positive and HIV-negative women. Nonetheless, being HIV-positive plays an important role in the development of cervical cancer.

[PMID: 34920716 PMCID: PMC8684193 DOI: 10.1186/s12904-021-00883-3] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/28/2021] [Accepted: 11/15/2021] [Indexed: 11/28/2022] Open
Abstract
Background The increasing burden of chronic non-communicable diseases in developing countries is driving attention to palliative care services. Identification of disease-specific symptoms of concern and their prevalence will guide designing, monitoring, and evaluating palliative care programmes. This study assessed the burden of symptoms and problems among patients with advanced cervical cancer. Methods This research followed a cross-sectional study design to quantitatively review the symptom burden among patients diagnosed with advanced cervical cancer attending treatment at Tikur Anbessa Specialised Hospital, Addis Ababa, Ethiopia from January to July 2019. Symptoms were assessed using a patient-reported, seven-day recall Integrated Palliative Care Outcome Scale (IPOS) version III. Frequency, median and mean scores with a standard deviation were used in the descriptive analysis whereas t-test and one-way analysis of variance were used for comparisons. Results There were 385 patients with advanced cervical cancer, stage IIB-IVB, successfully interviewed. The median age was 50 years, the majority were illiterate (63.1%) and in marital union (62.3%). Over 50% of the patients experienced pain, weakness, poor appetite, constipation, limited mobility, and dry mouth. The burdens of emotional symptoms such as patient anxiety, family anxiety, and patient depression were also prevalent at 79.7%, 82.3%, and 47.0%, respectively. Patients who are illiterate, at a higher stage of the disease, not currently in marriage, and who received palliative radiotherapy bear a higher symptom burden. Conclusion Patients with advanced cervical cancer bear a high symptom burden. Early initiation of palliative care is recommended to alleviate the concerning symptoms, and to improve patients’ quality of life.
