Cervical cancer risk factors among HIV-infected Nigerian women

Prediction of precancerous cervical cancer lesions among women living with HIV on antiretroviral therapy in Uganda: a comparison of supervised machine learning algorithms

BACKGROUND

Cervical cancer (CC) is among the most prevalent cancer types among women with the highest prevalence in low- and middle-income countries (LMICs). It is a curable disease if detected early. Machine learning (ML) techniques can aid in early detection and prediction thus reducing screening and treatment costs. This study focused on women living with HIV (WLHIV) in Uganda. Its aim was to identify the best predictors of CC and the supervised ML model that best predicts CC among WLHIV.

METHODS

Secondary data that included 3025 women from three health facilities in central Uganda was used. A multivariate binary logistic regression and recursive feature elimination with random forest (RFERF) were used to identify the best predictors. Five models; logistic regression (LR), random forest (RF), K-Nearest neighbor (KNN), support vector machine (SVM), and multi-layer perceptron (MLP) were applied to identify the out-performer. The confusion matrix and the area under the receiver operating characteristic curve (AUC/ROC) were used to evaluate the models.

RESULTS

The results revealed that duration on antiretroviral therapy (ART), WHO clinical stage, TPT status, Viral load status, and family planning were commonly selected by the two techniques and thus highly significant in CC prediction. The RF from the RFERF-selected features outperformed other models with the highest scores of 90% accuracy and 0.901 AUC.

CONCLUSION

Early identification of CC and knowledge of the risk factors could help control the disease. The RF outperformed other models applied regardless of the selection technique used. Future research can be expanded to include ART-naïve women in predicting CC.

Precancerous cervical lesion and associated factors among HIV-infected women in Ethiopia: systematic review and meta- analysis

BACKGROUND

Despite several preventative and control measures Ethiopia continues to see an increase in cervical cancer. Comprehensive evidence is very important to suggest ministry of health. Therefore, the aim of this study is to estimate the pooled violence of Precancerous Cervical Lesion and to identify associated factors among women living with HIV AIDS in Ethiopia.

METHODS

From February 15, 2024 to March 17, 2024, systematic and methodical search of the literature was conducted using electronic databases such as PubMed, HINARI, Global Health, Scopus, EMBASE, Web of Science, African Journal online (AJOL), and Google Scholar. Quality appraisal was assessed based on Joanna Briggs Institute (JBI) critical appraisal checklist for analytical cross-sectional study using 9 criteria. The Cochrane Q and I2 test statistics were used to verify the heterogeneity of the studies. Using a fixed effect model, the pooled estimate prevalence of precancerous cervical lesion among women living with HIV was calculated.

RESULTS

After reviewing 9,470 studies, 9 studies involving 2,910 women with HIV were included. The pooled estimate of precancerous cervical cancer among women living with HIV in Ethiopia was 15.34% (95% CI: 8.97, 21.72). Having history of sexual infection (POR = 3.12; 95% CI: 1.38, 7.05), having multiple sexual partner (POR = 3.14; 95% CI: 2.29, 4.30), and parity greater than two (POR = 4.97; 95% CI: 3.17, 7.78) were identified factors associated with precancerous cervical lesion.

CONCLUSION

This study found that about one-six of HIV-positive women developed precancerous cervical lesion. According to this study, there was a substantial correlation between precancerous cervical lesion among HIV-positive women and having history of sexually transmitted infection, having multiple sexual partners, and being multipara. In order to reduce precancerous cervical lesion, FMOH, policy makers, and interested parties should pay particular attention to this issue.

Factors Associated With Precancerous Cervical Lesions in Human Immunodeficiency Virus-Infected Women: A Cross-Sectional Survey in Togo

Background

The burden of human immunodeficiency virus (HIV) in cervical cancer remains a major public health challenge in developing countries, like Togo. Precancerous lesions include all cellular abnormalities that have malignant potential that can develop into cancer. The objective of this study was to determine the prevalence and factors associated with precancerous cervical lesions in HIV-infected women in our context.

Methods

A cross-sectional descriptive study was carried out from November 31, 2022, to January 31, 2023, in an HIV care center in Lomé (Non-Governmental Organization Espoir Vie Togo [NGO EVT] Grand-Lomé-Togo).

Results

A total of 271 women were included with a mean age of 47.0 years and a standard deviation of 10.0 years, among whom 20.7% do not have any scholar education. Only 6.7% of them had previously performed cervical smear examinations. The prevalence of precancerous cervical lesions observed in people living with human immunodeficiency virus (PLHIV) was 11.4% with a 95% confidence interval (CI) of 5.0 to 15.4. Cytological abnormalities were marked by low-grade squamous intraepithelial lesion (LSIL) (5.1%), followed by the presence of atypical squamous cells of undetermined significance (ASCUS) (3.5%). A statistically significant association was found between parity and the presence of precancerous lesions (P = .014).

Conclusions

In this study, more than 1 out of 10 women living with HIV had precancerous cervical lesions, and parity was the factor associated. The implementation of a systematic screening program for precancerous cervical lesions and human papillomavirus (HPV) infection integrated into HIV care is necessary for early treatment.

Precancerous cervical lesions and associated factors among women on antiretroviral therapy at Dukem Health Center, Central Ethiopia: A cross-sectional study

Background and Aims

Cervical cancer is a global public health problem and the second most common cancer which leads to morbidity and mortality among women in developing countries like Ethiopia. In Ethiopia, annually 6294 new cervical cancer cases and 4884 deaths are estimated in 2018 alone. This study aimed to assess the prevalence and associated factors of precancerous cervical lesions among women on antiretroviral therapy (ART) at Dukem Health Center, Central Ethiopia.

Methods

An institution-based cross-sectional study was carried out among randomly selected 257 women receiving ART at Dukem Health Center. Data were collected using a pretested structured questionnaire, medical record review, and visual inspection with acetic acid. Collected data were entered into Epi-info 7.4 and exported to SPSS version 26 for analysis. The prevalence of precancerous cervical lesions and the characteristics of study participants were identified. Utilizing both binary and multivariable logistic regression models, the existence and degree of association with precancerous cervical lesions were determined with a p value < 0.05 and a 95% confidence interval.

Results

The prevalence of precancerous cervical lesions was 16% (95% CI: 11.7-20.6). Significant association was found between precancerous cervical lesions and a history of STIs (AOR = 4.30, 95% CI: 1.48-12.49), oral contraceptive use (AOR = 6.56, 95% CI: 2.10-20.50), having multiple lifetime sexual partners (AOR = 2.53: 95% CI: 1.05-6.10), and a recent CD4 count of less than 200 cells/mm3 (AOR: 11.33, 95% CI: 2.88-24.58).

Conclusion

In the study area, the prevalence of precancerous cervical lesions was relatively high. Therefore, concerned bodies are recommended to increase awareness of the prevention of sexually transmitted diseases and limit sexual partners.

Vaginal microbiome community state types and high-risk human papillomaviruses in cervical precancer and cancer in North-central Nigeria

BACKGROUND

High risk human papillomaviruses (HR-HPV) have a causal role in cervical oncogenesis, and HIV-mediated immune suppression allows HR-HPV to persist. We studied whether vaginal microbiome community state types (CSTs) are associated with high-grade precancer and/or invasive cervical cancer (HSIL/ICC).

METHODS

This was a cross-sectional study of adult women with cervical cancer screening (CCS) at the Jos University Teaching Hospital (JUTH) in Jos, Nigeria, between January 2020 and February 2022. Cervical swabs underwent HPV genotyping (Anyplex™ II HPV28). Cervico-vaginal lavage (CVL) sample was collected for 16 S rRNA gene amplicon sequencing. We used multivariable logistic regression modelling to assess associations between CSTs and other factors associated with HSIL/ICC.

RESULTS

We enrolled 155 eligible participants, 151 with microbiome data for this analysis. Women were median age 52 (IQR:43-58), 47.7% HIV positive, and 58.1% with HSIL/ICC. Of the 138 with HPV data, 40.6% were negative for HPV, 10.1% had low-risk HPV, 26.8% had single HR-HPV, and 22.5% had multiple HR-HPV types. The overall prevalence of any HR-HPV type (single and multiple) was 49.3%, with a higher proportion in women with HSIL/ICC (NILM 31.6%, LSIL 46.5%, HSIL 40.8%, and 81.5% ICC; p = 0.007). Women with HIV were more likely to have HSIL/ICC (70.3% vs. 29.7% among women without HIV). In crude and multivariable analysis CST was not associated with cervical pathology (CST-III aOR = 1.13, CST-IV aOR = 1.31). However, in the presence of HR-HPV CST-III (aOR = 6.7) and CST-IV (aOR = 3.6) showed positive association with HSIL/ICC.

CONCLUSION

Vaginal microbiome CSTs were not significantly associated with HSIL/ICC. Our findings suggest however, that CST could be helpful in identifying women with HSIL/ICC and particularly those with HR-HPV. Characterization of CSTs using point-of-care molecular testing in women with HR-HPV should be studied as an approach to improve early detection and cervical cancer prevention. Future longitudinal research will improve our understanding of the temporal effect of non-optimal CST, HR-HPV, and other factors in cervical cancer development, prevention, and control.

Cervical Epithelial Abnormalities and Associated Factors among HIV-Infected Women in Lagos, Nigeria: A Cytology-Based Study

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.

Cervical Cytology and Herpes Simplex Virus Type-2 Serology Among Human Immune Deficiency Virus Infected Women on Highly Active Antiretroviral Therapy in Enugu, Nigeria

BACKGROUND

The prevalence of Human Immunodeficiency Virus (HIV) and Herpes Simplex Virus type-2 (HSV-2) infections are high and the programme for Cervical Cancer Screening is weak in Nigeria.

OBJECTIVES

Prevalence of Herpes Simplex Virus Type-2 co-infection and cervical cytology among HSV-2 co-infected Human Immunodeficiency Virus Sero-positive (HIV+) women on Highly Active Antiretroviral Therapy (HAART) attending Human Immunodeficiency Virus clinic at University of Nigeria Teaching Hospital (UNTH) Ituku/Ozalla Enugu, Nigeria.

METHODS

A cross-sectional, hospital-based study. Active participants included 105 HIV seropositive women on HAART and104 HIV seronegative (HIV-) women who passed inclusion criteria and signed written informed consent. Each participant was coded with a specific number. A structured questionnaire was used to obtain the socio-demographic and medical history. Serum was obtained for HSV-2 serology test for all participants and HIV screening for HIV-negative participants. Cervical smears were collected for Papanicolaou stains and Immunocytochemistry using anti-P16INKa antibody.

RESULTS

Prevalence of HSV-2+ was 50.5% among HIV+ women on HAART and 16.3% among HIV- women, Odds Ratios [95% CI]; p-value was 5.21 [2.74-9.94]; p < 0.0001. HIV+ women on HAART co-infected with HSV-2 significantly had more Cervical Lesions, 11.4% compared to HIVwomen uninfected with HSV-2, 4.8%, OR [95% CI]; p-value 4.8 (1.58-14.54); p = 0.006.

CONCLUSION

The prevalence of HSV-2 was significantly high among HIV+ women on HAART. HSV-2+ co-infection could be an enhancer of Cervical Lesions among HIV+ women on HAART. Hence, anti-herpetic agent introduction and screening for HSV-2 among HIV+ patients are recommended.

Precancerous Cervical Lesion Among Adult Women With Human Immune Deficiency Virus on Anti Retroviral Therapy At Saint Peter Specialized Hospital, Ethiopia: A Hospital-Based Cross-Sectional Study

Background

Cervical cancer is the fourth most frequent cancer in women representing 6.6% of all female cancers occurring in low and middle-income countries, where resources for cancer prevention programs are often scarce. So this study aimed to assess the prevalence of precancerous cervical lesion and associated factors among adult women with human immune deficiency virus (HIV) on Anti Retroviral Therapy (ART) at Saint Peter Specialized Hospital, Addis Ababa, Ethiopia.

Methods

An institution-based cross-sectional study was conducted from November 06 to July 20, 2020 among 267 adult women with HIV on Anti Retroviral Therapy At Saint Peter Specialized Hospital, Ethiopia. Data were collected using face-to-face interview, patient chart review, and the examination of the squamo-columnar junction by the visual inspection with the acetic acid method. The collected data were entered into Epi-data version 3.1 and exported to Statistical Package for the Social Sciences (SPSS) version 24.0 for analysis. Bivariate and multivariable binary logistic regression analysis were used to identify factors associated with the precancerous cervical lesion. Statistical significance was considered at a P-valve less than 0.05.

Result

A total of 267 women who were on ART were included in the study and the prevalence of precancerous cervical lesion was 7.5% with 95% CI =4.10%-10.50%. Modern family planning (AOR = 4.14, 95% CI = 1.23-13.87), history of sexual transmission infection (STI) (AOR=5.39, 95% CI= 1.56-18.70) and viral load (AOR=20.85, 95% CI = 6.19-70.25) had significant association with precancerous cervical lesion

Conclusion

In this study, the prevalence of precancerous cervical lesion is relatively low compared to studies in low and middle-income countries. Modern family planning, history of sexual transmitted infection, and viral load had a significant association with a precancerous cervical lesion. Hence, encouraging modern family planning, and routine screening of women for pre-cancerous cervical lesions for those with high viral load have enormous contributions to decreasing cervical cancer disease among Women with Human Immune Deficiency Virus through Anti Retroviral Therapy.

Mapping Evidence on the Burden of Breast, Cervical, and Prostate Cancers in Sub-Saharan Africa: A Scoping Review

Background

Cancer remains a major public health problem, especially in Sub-Saharan Africa (SSA) where the provision of health care is poor. This scoping review mapped evidence in the literature regarding the burden of cervical, breast and prostate cancers in SSA.

Methods

We conducted this scoping review using the Arksey and O'Malley framework, with five steps: identifying the research question; searching for relevant studies; selecting studies; charting the data; and collating, summarizing, and reporting the data. We performed all the steps independently and resolved disagreements through discussion. We used Endnote software to manage references and the Rayyan software to screen studies.

Results

We found 138 studies that met our inclusion criteria from 2,751 studies identified through the electronic databases. The majority were retrospective studies of mostly registries and patient files (n = 77, 55.8%), followed by cross-sectional studies (n = 51, 36.9%). We included studies published from 1990 to 2021, with a sharp increase from 2010 to 2021. The quality of studies was overall satisfactory. Most studies were done in South Africa (n = 20) and Nigeria (n = 17). The majority were on cervical cancer (n = 93, 67.4%), followed by breast cancer (67, 48.6%) and the least were on prostate cancer (48, 34.8%). Concerning the burden of cancer, most reported prevalence and incidence. We also found a few studies investigating mortality, disability-adjusted life years (DALYs), and years of life lost (YLL).

Conclusions

We found many retrospective record review cross-sectional studies, mainly in South Africa and Nigeria, reporting the prevalence and incidence of cervical, breast and prostate cancer in SSA. There were a few systematic and scoping reviews. There is a scarcity of cervical, breast and prostate cancer burden studies in several SSA countries. The findings in this study can inform policy on improving the public health systems and therefore reduce cancer incidence and mortality in SSA.

The Pattern of Cervical Cancer according to HIV Status in Yaoundé, Cameroon

Objective

To analyze the epidemiological aspects of invasive cervical cancer according to HIV status.

Methods

This was an historical cohort study from January 2010 to April 2017 in three hospitals at the Yaoundé city Capital, Cameroon, after the National Ethics Committee' approval. We included invasive cervical cancers with documented HIV status. Odds ratios and 95% confidence interval were calculated to assess the association between the different variables and HIV status. Survival was analyzed using the Kaplan–Meier. The level of significance was set up at <5%.

Results

Among the overall 213 cervical cancer patients, 56 were HIV+ (24.67%). Factors associated with positive HIV status were age below 40 (OR: 2.03 (1.38–2.67)), celibacy (OR: 2.88 (1.58–4.17)), nonmenopausal status (OR: 2.56 (1.36–3.75)), low parity, primiparity (OR: 2.59 (1.43–3.74)), and for parity with 2–4 children (OR: 2.24 (1.35–3.12)). Concerning the HIV+ patients, tumor was diagnosed late (stages III-IV) (OR: 2.70 (1.43–5.08)), undifferentiated (grade III) (OR: 7.69 (5.80–9.57)), with low median survival (9.83 months vs. 20.10 months).

Conclusion

HIV is frequent among cervical cancer patients. In the HIV+ patients, the diagnosis was made at the advanced stage, cells were poorly differentiated, and the prognosis was worse.

High-risk HPV genotypes in Zimbabwean women with cervical cancer: Comparative analyses between HIV-negative and HIV-positive women

BACKGROUND

High-risk human papillomavirus HPV (HR-HPV) modifies cervical cancer risk in people living with HIV, yet African populations are under-represented. We aimed to compare the frequency, multiplicity and consanguinity of HR-HPVs in HIV-negative and HIV-positive Zimbabwean women.

METHODS

This was a cross-sectional study consisting of women with histologically confirmed cervical cancer attending Parirenyatwa Group of Hospitals in Harare, Zimbabwe. Information on HIV status was also collected for comparative analysis. Genomic DNA was extracted from 258 formalin fixed paraffin embedded tumour tissue samples, and analysed for 14 HR-HPV genotypes. Data was analysed using Graphpad Prism and STATA.

RESULTS

Forty-five percent of the cohort was HIV-positive, with a median age of 51 (IQR = 42-62) years. HR-HPV positivity was detected in 96% of biospecimens analysed. HPV16 (48%), was the most prevalent genotype, followed by HPV35 (26%), HPV18 (25%), HPV58 (11%) and HPV33 (10%), irrespective of HIV status. One third of the cohort harboured a single HPV infection, and HPV16 (41%), HPV18 (21%) and HPV35 (21%) were the most prevalent. HIV status did not influence the prevalence and rate of multiple HPV infections (p>0.05). We reported significant (p<0.05) consanguinity of HPV16/18 (OR = 0.3; 95% CI = 0.1-0.9), HPV16/33 (OR = 0.3; 95% CI = 0.1-1.0), HPV16/35 (OR = 3.3; 95% CI = 2.0-6.0), HPV35/51 (OR = 6.0; 95%CI = 1.8-15.0); HPV39/51 (OR = 6.4; 95% CI = 1.8-15), HPV31/52 (OR = 6.2; 95% CI = 1.8-15), HPV39/56 (OR = 11 95% CI = 8-12), HPV59/68 (OR = 8.2; 95% CI = 5.3-12.4), HPV66/68 (OR = 7; 95% CI = 2.4-13.5), independent of age and HIV status.

CONCLUSION

We found that HIV does not influence the frequency, multiplicity and consanguinity of HR-HPV in cervical cancer. For the first time, we report high prevalence of HPV35 among women with confirmed cervical cancer in Zimbabwe, providing additional evidence of HPV diversity in sub-Saharan Africa. The data obtained here probes the need for larger prospective studies to further elucidate HPV diversity and possibility of selective pressure on genotypes.

Risk factors for precancerous cervical lesion among women screened for cervical cancer in south Ethiopia: Unmatched case-control study

Background

Nearly 90% of deaths from cervical cancer occur in a low resource setting. In Ethiopia, the magnitude of precancerous cervical lesions ranges from 7% to 28%. Precancerous cervical lesions may progress to cervical cancer. Early screening and treatment of precancerous cervical lesions is a cost-effective way to avert the growth of cervical cancer. However, there has been limited research on risk factors for precancerous cervical lesions in Ethiopia. Therefore, this study aimed to identify risk factors for precancerous cervical lesions among women screened for cervical cancer in south Ethiopia.

Method

A facility-based unmatched case-control study was carried out in five health facilities in south Ethiopia between 8 May to 28 September 2018. Interviewer administered questionnaires were used to collect data from 98 cases and 197 controls. Multivariate logistic regression was employed to identify determinants of precancerous cervical lesions.

Results

Women aged 30–39 years (AOR = 2.51, 95% CI: 1.03–6.08), monthly income ≤66 (AOR = 3.51, 95% CI: 1.77–6.97), initiation of first sexual intercourse at age less than or equal to 20 (AOR = 2.39, 95% CI: 1.14–5.47), having more than one lifetime sexual partner (AOR = 4.70, 95% CI: 2.02–10.95), having a partner/ husband with more than one lifetime sexual partner (AOR = 2.98, 95% CI: 1.35–6.65) had higher odds of precancerous cervical lesions.

Conclusion and recommendation

Strategies to prevent precancerous cervical lesions should focus on modification of lifestyle and sexual behaviour. The findings of this study highlight several implications for policymakers: targeting older women for cervical cancer screening, addressing inequalities and education relating to risky sexual behaviour may reduce precancerous cervical lesions. Furthermore, future longitudinal studies are needed to assess the awareness of women about cervical cancer screening.

Urban Poor Community Settings' Knowledge and Screening Practices for Cervical Cancer in Ibadan, Nigeria

PURPOSE

This study investigated knowledge and screening practices for cervical cancer among two urban poor community settings in Ibadan, Nigeria.

METHODS

A cross-sectional design was used. ODK tool was used to collect quantitative data among a sample size of 500 respondents. Data were analyzed using IBM SPSS version 21 for descriptive and inferential statistics. Scores for knowledge were on a scale of 0-39 points (0-18 low, 19-23 fair, and 24-39 high knowledge).

RESULTS

A majority of respondents (77.2%) had low knowledge of cervical cancer and were not aware (93.6%) of the Papanicolaou test (Pap smear test) or cervical cancer screening (91.2%). Very few women (10%) were aware of the human papillomavirus vaccine for the prevention of cervical cancer, 4% had been screened with the Papanicolaou test, and one woman (0.3%) with visual inspection with acetic acid. Four (1.1%) women had taken human papillomavirus vaccine before.

CONCLUSION

The findings of this study have underscored a necessity for increased awareness creation through health promotion interventions and strategies to alleviate low knowledge, prevention, and screening practices for cervical cancer in poor community settings in Nigeria.

Fatal Infections Among Cancer Patients: A Population-Based Study in the United States

Introduction

Cancer patients are prone to infections, but the mortality of fatal infections remains unclear. Understanding the patterns of fatal infections in patients with cancer is imperative. In this study, we report the characteristics, incidence, and predictive risk factors of fatal infections among a population-based cancer cohort.

Methods

A total of 8,471,051 patients diagnosed with cancer between 1975 and 2016 were retrospectively identified from the Surveillance, Epidemiology, and End Results (SEER) program. The primary outcome was dying from fatal infections. Mortality rates and standardized mortality ratios (SMRs) adjusted for age, sex, race, and calendar year were calculated to characterize the relative risks of dying from fatal infections and to compare with the general population. Furthermore, cumulative mortality rates and the Cox regression models were applied to identify predictive risk factors of fatal infections.

Results

In cancer patients, the mortality rate of fatal infections was 260.1/100,000 person-years, nearly three times that of the general population [SMR, 2.92; 95% (confidence interval) CI 2.91–2.94]. Notably, a decreasing trend in mortality rate of fatal infections was observed in recent decades. SMRs of fatal infections were highest in Kaposi sarcoma (SMR, 162.2; 95% CI 159.4–165.1), liver cancer (SMR, 30.9; 95% CI 30.0–31.8), acute lymphocytic leukemia (SMR, 19.1; 95% CI 17.0–21.4), and acute myeloid leukemia (SMR, 13.3; 95% CI 12.4–14.3). Patients aged between 20 and 39 years old exhibited a higher cumulative mortality rate in the first few years after cancer diagnosis, whereas the cumulative mortality rate of those > 80 years old was rapidly increasing and became the highest approximately 3 years post-cancer diagnosis. Predictive risk factors of dying from fatal infections in cancer patients were the age of 20–39 or > 80 years, male sex, black race, diagnosed with cancer before 2000, unmarried status, advanced cancer stage, and not receiving surgery and radiotherapy, but receiving chemotherapy.

Conclusion

Cancer patients were at high risks of dying from infectious diseases. Certain groups of cancer patients, including those aged between 20 and 39 or > 80 years, as well as those receiving chemotherapy, should be sensitized to the risk of fatal infections.

Knowledge, attitude, and practice of cervical cancer screening among women living with HIV in the Kilimanjaro region, northern Tanzania

Background

Cervical cancer is the fourth most common cancer globally among women in incidence and mortality. Women living with HIV (WLHIV) are disproportionately at a higher risk of developing the disease.

Aim

To determine the knowledge, attitude, and practice of cervical cancer screening among WLHIV in the Kilimanjaro region, northern Tanzania, following the integration of these services in routine HIV care in the country.

Methods and results

A cross‐sectional study was conducted in the Kilimanjaro region among 297 WLHIV attending care and treatment centers (CTC) in Hai district and Mawenzi regional hospitals in northern Tanzania between 21 August and 3 September 2020. A questionnaire was used for data collection using face‐to‐face interviews. Data were analyzed using SPSS version 20.0. Frequencies and percentages summarized categorical variables and numerical variables summarized using median and interquartile range (IQR). About half (50.2%) of 297 WLHIV in this study had ever screened for cervical cancer, and 64% screened within the past 12 months preceding the survey. Although 90% ever heard of cervical cancer screening, only 20.5% knew when WLHIV should start screening. Over half (52.5%) had adequate knowledge of prevention, 38.4% on risk factors, and 27.9% of cervical cancer signs and symptoms. Two‐thirds (66.7%) had positive attitudes toward cervical cancer screening. A major source of cervical cancer screening information was the health care providers (80.1%) and the mass media (66%), particularly radio.

Conclusions

The WLHIV in this study had inadequate knowledge but favorable attitudes toward cervical cancer screening, while half had screened for cervical cancer. Efforts should be directed to capacity building of health care providers at CTC and scaling up the mass media campaigns as relevant interventions to promote the uptake of cervical cancer screening programs among WLHIV in Tanzania.

Trends in Premature Deaths among Women Living with HIV/AIDS and Cervical Cancer

OBJECTIVES

There is a lack of updated information on premature death and years of potential life lost (YPLL) among human immunodeficiency (HIV)-positive women with cervical cancer. We hypothesize that increased access to preventive resources such as antiretroviral therapy, preexposure prophylaxis, and human papillomavirus vaccines has reduced premature mortality and YPLL in these women in the previous decades.

METHODS

We used data from the National Inpatient Sample database from 2003 to the third quarter of 2015, and restricted the analysis to HIV-positive women with or without cervical cancer. Joinpoint regression models were run to identify trends in the rates of HIV and cervical cancer. Overall and age-stratified YPLL were calculated for HIV-positive women with cervical cancer. Adjusted survey logistic regression models were built to determine the predictive factors of in-hospital mortality among women living with HIV.

RESULTS

Among hospitalized women, low-income, non-Hispanic Blacks, and patients aged 40 to 59 years experienced greater frequencies of HIV/cervical cancer comorbidity. The prevalence of HIV hospitalizations increased by an average annual percentage of 0.9% (95% confidence interval 0.3-1.6). YPLL decreased in HIV-positive women living with and without cervical cancer by 4.9% and 4.3%, respectively. The trajectory for YPLL was not uniform across age groups. YPLL decreased substantially in women aged 20 to 29 years with HIV/cervical cancer comorbidity. Cervical cancer remained a significant predictor of mortality among HIV-positive women when adjusted for age, race, and insurance coverage.

CONCLUSIONS

Within a large, national sample from 2003 to 2015, we found an overall declining trend in YPLL in women living with HIV/cervical cancer comorbidity. In-hospital mortality among HIV-positive women was associated with cervical cancer, age, race, and insurance coverage. We recommend further investigation into the quality of HIV and cervical cancer treatment and prevention services for the sociodemographic groups described.

Uptake of cervical cancer screening service and associated factors among age-eligible women in Ethiopia: systematic review and meta-analysis

BACKGROUND

Cervical cancer is the leading cause of cancer deaths among women in developing countries. Since cervical cancer is a preventable disease, screening is an important control and prevention strategy, recommended by the World Health Organization (WHO) for all women aged 30 years and older, and even earlier for some high-risk women. Therefore the aim of this study was to assess the uptake of cervical cancer screening among age-eligible women in Ethiopia.

METHOD

Review identification was performed through the search of online databases PubMed, Google Scholar, HINARI, EMBASE, Science Direct, Cochrane library, African Journals, and other gray and online repository accessed studies were searched using different search engines. For critical appraisal of studies, Newcastle-Ottawa Quality Assessment Scale (NOS) was used. The analysis was conducted by using STATA 11 software. To test the heterogeneity of studies, the Cochran Q test and I2 test statistics were used. To detect publication bias of the studies, the funnel plot and Egger's test were used. The pooled prevalence of cervical cancer screening and the odds ratio (OR) with a 95% confidence interval were presented using forest plots.

RESULT

Twenty-four studies with a total of 14,582 age-eligible women were included in this meta-analysis. The pooled national level of cervical cancer screening among age-eligible women in Ethiopia was 13.46% (95%CI:11.06,15.86). Knowledge on cervical cancer and screening (OR = 4.01,95%CI:2.76,5.92), history of multiple sexual partners (OR = 5.01, 95%CI:2.61,9.61), women's age (OR = 4.58, 95%CI:2.81,7.46), history of sexually transmitted disease (OR = 4.83,95%CI:3.02,7.73), Perceived susceptibility to cervical cancer (OR = 3.59, 95%CI:1.99,6.48), getting advice from health care providers (OR = 4.58, 95%CI:3.26, 6.43), women's educational level (OR = 6.68,95%CI:4.61,9.68), women's attitude towards cervical cancer and screening (OR = 3.42, 95%CI:2.88,4.06) were the determinant factors of cervical cancer screening uptake among age-eligible women in Ethiopia.

CONCLUSION

The pooled prevalence of cervical cancer screening was remarkably low among age-eligible women in Ethiopia. Thus, to increase the uptake of cervical cancer screening among age-eligible women regularly, it is better to create awareness programs for early detection and treatment of cervical cancer, and educational interventions that teach the step-by-step practice of cervical screening to increase women's attitude for screening. Additionally, it is better to inform every woman is susceptible to cervical cancer, especially after starting sexual intercourse, and screening remains fundamental in the fight against cervical cancer before becoming invasive. Moreover, counseling and improving the confidence of women by health care providers to undergo screening is recommended.

Abnormal cervical cytology amongst women infected with human immunodeficiency virus in Limpopo province, South Africa

Background

Cervical cancer remains the major public problem worldwide and the most common gynaecological malignancy in the developing world, particularly in sub-Saharan Africa.

Aim

To determine the prevalence of abnormal cervical cytology amongst women with and without human immunodeficiency virus (HIV) and examine the association between HIV and histological grading.

Setting

The study was conducted in Limpopo province, which is the northernmost province of South Africa. The province has five district municipalities with one tertiary, five regional and thirty four district hospitals.

Methods

We retrospectively reviewed cervical cancer cases in Limpopo province (LP) of South Africa, using data collected routinely by the National Health Laboratory Services (NHLS). The data on smears submitted for cytology between 2013 and 2015 were extracted from the Central Data Warehouse (CDW) database.

Results

A total of 84 466 women were screened for cervical cytology smears. Their mean age was 39.8 ± 13.6 years, with range from 15 to 113 years; 77.2% were in the age group 30 years and older and 19.6% had an abnormal cervical cytology result. Overall, 46.4% of the women screened for cervical cancer were HIV infected. A significantly higher proportion of HIV-positive women had abnormal cytology than HIV-negative women (31.8% vs. 9.2%).

Conclusion

The prevalence of abnormal cytology amongst HIV-positive women is relatively high, and the risk appears to be significantly greater in all age groups. This finding highlights the need to ascertain HIV status of all women presenting with cervical cancer.

Prevalence and predictors of precancerous cervical lesions among HIV-positive women in Jos, north-central Nigeria

OBJECTIVE

To determine the prevalence and predictors of precancerous cervical lesions among HIV-positive women in Jos, Nigeria.

METHODS

A cross-sectional study was conducted from October 2017 to January 2018 among 326 HIV-positive women. Cervical smears were collected for examination at the AIDS Preventive Initiative of Nigeria clinics of Jos University Teaching Hospital (JUTH) and Bingham University Teaching Hospital (BhUTH), Jos, Nigeria. Demographic characteristics of participants were documented using a structured questionnaire. Data were entered and analyzed using SPSS version 21.

RESULTS

Of the 326 participants, precancerous cervical lesions were present in 40 (12.2%) women: 4 (1.2%) had atypical squamous cells of undetermined significance, 19 (5.8%) had low-grade squamous intraepithelial lesions, 1 (0.3%) had atypical squamous cells cannot exclude high-grade squamous intraepithelial lesions, 13 (4.0%) had high-grade squamous intraepithelial lesions, and 3 (0.9%) had high-grade squamous intraepithelial lesions, suspected for invasion. The multivariate logistics regression model showed that parity (odds ratio 3.4, 95% confidence interval 1.3-9.5, P=0.043) was a significant predictor of precancerous cervical lesions.

CONCLUSION

The prevalence of precancerous cervical lesions among HIV-infected women is relatively low compared to earlier reported prevalence in an HIV population in Jos. Increasing parity was a significant predictor.

Sociodemographic factors, health seeking behaviors, reproductive history, and knowledge of cervical screening among women in Swaziland

BACKGROUND

Cervical cancer is the leading cause of cancer among women in Swaziland; however, a low rate of cervical screening in this population has led to high rates of morbidity and mortality from cervical cancer.

OBJECTIVE

To identify factors associated with lack of cervical screening among women in Swaziland.

METHODS

A cross-sectional study was conducted among 300 women aged 18-69 years attending clinics in three regions of Swaziland from May to August of 2014. An investigator-administered questionnaire was used to collect data on socioeconomic factors, health-seeking behaviors, reproductive history, and cervical screening history and knowledge from the women.

RESULTS

Adjusted multivariable logistic regression analysis revealed that women < 30 years of age were less likely to receive a cervical exam compared to women ≥30 years of age (Odds Ratio 0.06, 95% Confidence Interval 0.01-0.67). Women who had a tertiary education were almost 6 times more likely to receive a cervical screening (OR 5.83, 95% CI 1.11-30.50). Women who said that they did not know when to receive cervical screening were 73% less likely to have a cervical exam (OR 0.27, 95% CI 0.01-0.74).

CONCLUSIONS

Younger age, lower educational level, and lack of knowledge about when to receive a cervical screening affected whether women obtained a cervical screening. This indicates the need for educating women, particularly younger women, about the importance of cervical examinations. Addressing these barriers to screening should lead to a decrease in cervical lesions and cancer, especially in this high HIV-positive population.

A systematic review of self-sampling for HPV testing in Africa

BACKGROUND

Human papillomavirus (HPV) testing may be feasible for primary cervical cancer screening in low-resource countries.

OBJECTIVE

To compare self-sampling by women with clinician-performed sampling for HPV testing in Africa.

SEARCH STRATEGY

MEDLINE, Google scholar, EMBASE, and several journals were searched from 2000 until 2015 using relevant terms.

SELECTION CRITERIA

Selected studies compared self-sampled and clinician-sampled HPV tests.

DATA COLLECTION AND ANALYSIS

Data extraction forms included description of the type of HPV screening, description of any additional intervention components, study design, sample size, follow-up periods, analytic approach, reported numerical outcomes, results, and limitations.

RESULTS

Twenty-five studies were identified. Women of a wide age range were successful at self-sampling in many African countries. More than 95% of self-samples yielded HPV DNA results. The concordance in test results between self-collected samples and clinician-collected samples was reasonably high in most studies. In all studies, the quality of cytology from self-sampling matched that of clinician-sampling. Women were generally positive about self-collection, but noted some concerns.

CONCLUSION

Self-sampling for HPV DNA testing seems to represent a feasible alternative to the Pap test. Further research is needed to provide a solid evidence base to inform using of self-sampling for HPV DNA testing for primary cervical cancer screening.

Prevalence and Risk Factors of Cervical Dysplasia among Human Immunodeficiency Virus Sero-Positive Females on Highly Active Antiretroviral Therapy in Enugu, Southeastern, Nigeria

OBJECTIVE

Evaluation of prevalence and risk factors of cervical dysplasia among Human Immunodeficiency Virus sero-positive (HIV+ve) females on Highly Active Antiretroviral Therapy (HAART) attending HIV clinic at University of Nigeria Teaching Hospital (UNTH) Enugu, Southeastern, Nigeria.

METHODS

Structured questionnaire was used to obtain socio-demographic and risk factors data. Cervical specimens were collected from 105 HIV +ve females on HAART and 104 HIV seronegative (HIV-ve) females. Pap smears were collected using cytobrush and Ayre's spatula in a secluded place. Smears were made on slides and placed in 95% ethyl alcohol for conventional Pap staining and the cytobrush washed into the preservative containers for later Immunocytochemistry staining. Blood samples were used for HIV screening. Immunocytochemistry activity using anti-P16INK4A was carried out on the Pap smears that were positive for cervical dysplasia.

RESULTS

Pap staining showed prevalence of cervical dysplasia among HIV+ve on HAART 19.05%, (ASCUS 14.29%, LSIL 3.81%, HSIL 0.95%) whereas HIV-ve was 6.73%, p = 0.008. Only the HSIL 0.95% was positive for P16INK4A. Odds ratios at 95% Confident Interval of the risk factors of cervical dysplasia were thus; HIV+ve, 3.26 (1.31-8.09), education less than secondary school 3.23 (1.25-8.37), polygamy 3.23 (1.25-8.37), smoking 1.36 (0.15-12.10), married 2.08 (0.43-2.31), grand multi gravidity 1.72 (0.72-4.11), grand multi parity 1.54 (0.66-3.61), positive history of sexually transmitted diseases 2.49 (1.06-5.80). Uptake of cervical cancer screening was low in both study groups, 7 (6.7%) among HIV+ve on HAART and 14 (13.5%) among HIV-ve females, P = 0.102.

CONCLUSION

HAART had cytoprotective effect against cervical dysplasia in HIV+ve females, by reducing progression of ASCUS to LSIL, HSIL and cervical cancer. Progression from normal to ASCUS increased which could be due to latency or/and prolonged persistent high risk HPV and HIV infections, of the most sexually active age group before diagnosed of HIV.

Precancerous cervical lesion and associated factors among HIV-infected women on ART in Amhara Regional State, Ethiopia: A hospital-based cross-sectional study

OBJECTIVE

Cervical cancer, which is caused by human papillomavirus, is one of the common cancers in women worldwide. The proportion of precancerous cervical lesion among HIV-infected women has not been investigated yet in this study area. The aim of this study was to determine the proportion of precancerous cervical lesion and associated factors among HIV-infected women on ART in Woldia and Dessie Hospitals, Amhara Regional State, Ethiopia.

METHODS

A hospital-based cross-sectional study was conducted on 284 HIV patients. Data were collected using a structured questionnaire and visual inspection. Pap smear test was employed for confirmation of cancer. Descriptive statistics were used to summarize findings. A logistic regression model was considered to identify predictors of precancerous cervical lesions. Those variables with P < 0.05 at a 95% confidence interval were considered as statistically significant.

RESULTS

The overall proportion of precancerous lesion among HIV-infected women in this study was 9.9%. Among HIV-infected women age greater than 30 years old, single in marital status, commercial sex worker, had any other sexually transmitted infection, more than one sexual partner, more than two children and with vaginal wall abnormality were factors associated with the occurrence of precancerous cervical lesion.

CONCLUSION

The proportion of precancerous cervical lesion among HIV-infected women was low compared to some previous studies conducted among HIV-infected women in Ethiopia. Therefore, regular screening of HIV-infected women for precancerous cervical lesion is very important by giving especial consideration to identified associated factors.

Precancerous lesions of cervix among women infected with HIV in Referral Hospitals of Amhara Region, Northwest Ethiopia: a cross sectional study

BACKGROUND

The risk of death from complications related to cancer of the cervix is a main health problem over the course of a woman's life in low income countries. It commonly affects women infected with HIV. Therefore, screening women infected with HIV should start in low income countries, including Ethiopia.

METHODS

We conducted an institution based cross-sectional study from September 1st, 2015 to December 30th, 2015. During the study, 435 women were included in the study. The data were collected through face to face interviews and patient chart review using pre-tested and structured questionnaires. Data was also collected through visual inspection with acetic acid applied for screening and treatment. Data was entered into Epi-info version 7, cleaned and analyzed using SPSS version 20. Logistic regression analysis fitted and odds ratio with 95% confidence interval were computed.

RESULTS

The overall prevalence of pre-cancerous lesions of the cervix was 20.2% (95%CI: 13%, 29%). Having more than one lifetime sexual partner (AOR=2.91, 95%CI:1.13, 7.52), a history of sexually transmitted disease (AOR=4.04, 95%CI: 2.19, 7.44), age at first birth less than 18 years (AOR=3.36, 95%CI: 1.79, 5.01) and baseline CD4 count less than 200 cells/mm3 (AOR=7.51, 95%CI: 3.58, 15.68) were significantly associated with pre-cancerous lesion of the cervix.

CONCLUSION

This study points out the prevalence of pre-cancerous lesions of the cervix is high. Thus, the findings recommend raising of a screening strategy for cervical intraepithelial neoplasia for all women living with HIV should be undertaken. In addition, awareness creation about the impact of multiple sexual partner, promotion of early HIV diagnosis and timely baseline CD4 cell count is important.

Precancerous Cervical Lesion Among HIV-Positive Women in Sub-Saharan Africa: A Systematic Review and Meta-Analysis

In sub-Saharan Africa, cervical cancer is an intersecting epidemic with HIV and it is the second most common cause of cancer-related deaths in women. Therefore, this study was aimed to estimate the current status of the prevalence and associated factors of precancerous cervical lesions among HIV-positive women in sub-Saharan Africa. A systematic literature search was conducted from legitimate electronic databases, including MEDLINE (Ovid), PubMed, EMBASE (Ovid), Emcare (Ovid), CINAHL (EBSCOhost), Web of Science, Scopus, and PopLine and other gray literature including Google, Google Scholar, World Cat, ResearchGate, and Mednar. Data were extracted with a structured format prepared in Microsoft Excel. Each study was evaluated using the Joanna Briggs Institute critical appraisal tool for cross-sectional and cohort studies checklists. Accordingly, medium and high-quality studies were included in the review. Data synthesis and statistical analysis was conducted using OpenMeta and comprehensive meta-analysis version 2 software. The study protocol is registered on PROSPERO with ID: CRD42018114266. The pooled prevalence of precancerous cervical lesion among HIV-positive women in sub-Saharan Africa was 25.6% (95% confidence interval [CI]: 19.4%-31.8%). Having more than 2 lifetime sexual partners (odds ratio [OR]: 4.77; 95% CI: 1.35-16.93), having had a history of sexually transmitted infections (STIs; OR: 1.92; 95% CI: 1.03-3.57), having more than 2 births (OR: 1.84; 95% CI: 1.33-2.53), and CD4 count <200 cells/mm3 (OR: 1.765; 95% CI: 1.23-2.535) were significantly associated with precancerous cervical lesions. The prevalence of precancerous cervical lesion among HIV-positive women was high. One in 4 HIV-infected women suffers from precancerous cervical lesion. Lower CD4 cell count, STIs, multiple sexual partnering, and histories of multiple births and abortions were the foremost contributing factors for this burden. Precancerous cervical lesion could be reduced significantly if preventive and promotive measures are done on the associated factors.

Awareness, Knowledge and Attitudes Towards Cervical Cancer Amongst HIV-Positive Women Receiving Care in a Tertiary Hospital in Nigeria

The incidence of cervical cancer (CC) in the sub-Saharan Africa region, where Nigeria is located, is amongst the highest in the world; it is estimated that 70,722 new cases of invasive cervical cancer occur annually in sub-Saharan Africa. Immunosuppression, especially due to human immunodeficiency virus (HIV) infection, is a predisposing factor for persistent infection with high-risk human papilloma virus (HR-HPV) and the development of squamous intraepithelial lesions. Four hundred and fifty women who attended the HIV clinic at the Nnamdi Azikiwe University Teaching Hospital, Nnewi, and who consented to participate in the study were randomly selected. They were given self-administered questionnaires which sought to determine their awareness and knowledge of cervical cancer and attitudes towards cervical cancer screening and prevention. The media 23% (n = 103) was the most common source of information amongst respondents who had heard about cervical cancer. For all the women surveyed, the average percentage knowledge was 9.95%. Having attitude scores greater than or equal to the mean attitude score of 55.16% was regarded as having a positive attitude while a score lower than that was regarded as negative attitude. About 43.5% (n = 195) respondents had a positive attitude towards cervical cancer screening and prevention. Cervical cancer awareness and knowledge amongst women attending the HIV clinic in the Nnamdi Azikiwe University Teaching Hospital, Nnewi, were very poor. Their attitude towards cervical cancer screening practices and prevention was also very poor.

Awareness of cervical cancer among women attending an HIV treatment centre: a cross-sectional study from Morocco

OBJECTIVE

To explore awareness about cervical cancer among Moroccan women attending an HIV treatment centre in Laâyoune city, Morocco.

DESIGN

A cross-sectional study was conducted from April to June 2017 using a knowledge test regarding cervical cancer, its risk factors and its prevention.

SETTING

HIV treatment centre at the Hospital of Moulay Hassan Ben Elmehdi in Laâyoune city, Morocco.

PARTICIPANTS

One hundred and twenty-three HIV-positive women aged 19 years and older were recruited to this study.

RESULTS

A total of 115 women were eligible to participate in the study. The average age was 34.9±10.2 years. Few women (20%) had heard about cervical cancer and its screening, the majority (17.4%) having received information from mass media. The vast majority (79.1%) of respondents had no knowledge of cervical cancer risk factors, and 80.8% did not know any symptoms of cervical cancer. Only 13% had undergone a Pap smear test. The main reason for not seeking Pap smear was the absence of symptoms (47%).

CONCLUSION

Our study documents poor awareness of cervical cancer. Given that the HIV-positive population is at increased risk of cervical cancer, health education programmes should be promoted to increase awareness of cervical cancer as well as access and participation in cervical cancer screening.

Noncommunicable diseases among HIV-infected persons in low-income and middle-income countries: a systematic review and meta-analysis

OBJECTIVE

To appropriately identify and treat noncommunicable diseases (NCDs) among persons living with HIV (PLHIV) in low-and-middle-income countries (LMICs), it is imperative to understand the burden of NCDs among PLHIV in LMICs and the current management of the diseases.

DESIGN

Systematic review and meta-analysis.

METHODS

We examined peer-reviewed literature published between 1 January 2010 and 31 December 2016 to assess currently available evidence regarding HIV and four selected NCDs (cardiovascular disease, cervical cancer, depression, and diabetes) in LMICs with a focus on sub-Saharan Africa. The databases, PubMed/MEDLINE, Cochrane Review, and Scopus, were searched to identify relevant literature. For conditions with adequate data available, pooled estimates for prevalence were generated using random fixed effects models.

RESULTS

Six thousand one hundred and forty-three abstracts were reviewed, 377 had potentially relevant prevalence data and 141 were included in the summary; 57 were selected for quantitative analysis. Pooled estimates for NCD prevalence were hypertension 21.2% (95% CI 16.3-27.1), hypercholesterolemia 22.2% (95% CI 14.7-32.1), elevated low-density lipoprotein 23.2% (95% CI 15.2-33.6), hypertriglyceridemia 27.2% (95% CI 20.7-34.8), low high-density lipoprotein 52.3% (95% CI 35.6-62.8), obesity 7.8% (95% CI 4.3-13.9), and depression 24.4% (95% CI 12.5-42.1). Invasive cervical cancer and diabetes prevalence were 1.3-1.7 and 1.3-18%, respectively. Few NCD-HIV integrated programs with screening and management approaches that are contextually appropriate for resource-limited settings exist.

CONCLUSION

Improved data collection and surveillance of NCDs among PLHIV in LMICs are necessary to inform integrated HIV/NCD care models. Although efforts to integrate care exist, further research is needed to optimize the efficacy of these programs.

Recent advances in cancer outcomes in HIV-positive smokers

HIV-infected smokers are at relatively higher risk of cancer than HIV-infected non-smokers. HIV weakens the immune system and renders infected individuals more vulnerable to the carcinogenic effects of smoking. HIV-infected smokers suffer more aggressive forms of cancers than do non-smokers because of the cumulative effects of the virus and cigarette smoke carcinogens. The major types of cancer observed in HIV-infected smokers are lung, head and neck, esophageal, anal, and cervical cancers. In this review, we will discuss the recent advances in cancer outcomes, primarily in terms of cancer incidence, prevalence, and progression in HIV patients who are smokers.

Screening for human papillomavirus, cervical cytological abnormalities and associated risk factors in HIV-positive and HIV-negative women in Rwanda

OBJECTIVES

Cervical cancer is the major cause of death from cancer in Africa. We wanted to assess the prevalence of human papillomavirus (HPV) infections and associated risk factors and to determine whether HPV testing could serve as a screening method for squamous intraepithelial lesions (SILs) in Rwanda. We also wanted to obtain a broader understanding of the underlying risk factors for the establishment of HPV infection in Rwanda.

METHODS

A total of 206 HIV-positive women, 172 HIV-negative women and 22 women with unknown HIV status were recruited at the University Teaching Hospitals of Kigali (UTHK) and of Butare (UTHB) in Rwanda. Participants underwent an interview, cervical sampling for a Thinprep Pap test and a screening test analysing 37 HPV strains.

RESULTS

Only 27% of HIV-positive women and 7% of HIV-negative women had been screened for cervical cancer before. HPV16 and HPV52 were the most common HPV strains. HIV-positive women were more commonly infected with high-risk (HR) HPV and multitype HPV than HIV-negative women. The sensitivity was 78% and the specificity 87% to detect high-grade SIL (HSIL) with HPV screening. Among HIV-negative women, being divorced was positively associated with HR-HPV infection, while hepatitis B, Trichomonas vaginalis infection and HR-HPV infection were factors positively associated with SILs. Ever having had gonorrhoea was positively associated with HR-HPV infection among HIV-positive women. HR-HPV infection and the number of live births were positively associated with SILs.

CONCLUSIONS

The currently used quadrivalent vaccine may be insufficient to give satisfactory HPV coverage in Rwanda. HPV Screening may be effective to identify women at risk of developing cervical cancer, particularly if provided to high-risk patients.

Characteristics of cervical disease among symptomatic women with histopathological sample at Hawassa University referral hospital, Southern Ethiopia

Background

Cervical cancer is one of the most common cancers of women in developing countries. It is also eminent cause of mortality and morbidity in women worldwide. Symptoms usually develop when the cancer has become invasive and invade nearby tissue. This has significant effect on treatment of cases in area where there is limited awareness. The aim of this study is to describe cervical disease among symptomatic women with a histhological sample at Hawassa University referral hospital, southern Ethiopia.

Methods

Five years retrospective histopathological characteristics of symptomatic cervical cases were studied from January, 2010 to January, 2015 at Hawassa University referral hospital pathology laboratory. Clinical diagnosis of patients, patient’s age, biopsy sample size and type, and microscopic finding of the cases were collected for this study. The data were entered by Epi-Info statistical software version 7 and later exported to SPSS version 20 for analysis. Descriptive analyses such as frequency, mean, and standard deviation were computed.

Results

A total of 513 patients with cervical lesion were examined histopathologically in the study period. The age ranges of the patients were from 17 to 85 years with mean and standard deviation of 42 ± 11 years. Of these symptomatic examined cases, 253 (49.3%) of them were cancerous lesion while non cancerous and precancerous cases account 166 (32.4%) and 51 (9.9%) respectively. Cervical squamous cell carcinoma was the predominant type cancer which accounts 211(83.4%) of all cancerous cervical cases. The proportion of cervical cancer was higher in age group older than 60. The magnitude of cervical cancer and precancerous cases were steadily increasing throughout study periods whereas non cancerous cases were fluctuating.

Conclusions

Cervical cases were associated with wide range of disorders. Cervical cancer was the predominant cervical disease in symptomatic southern Ethiopian women. The high proportion of cervical cancer was observed in post-menopausal age when compared with other cervical cases. Effective uses of low-tech and inexpensive screening tools that already exist and giving awareness about the disease in combination with vaccine could reduce this high magnitude of cervical cancer in study area.

Associations between highly active antiretroviral therapy and the presence of HPV, premalignant and malignant cervical lesions in sub-Saharan Africa, a systematic review: current evidence and directions for future research

OBJECTIVES

In sub-Saharan Africa, substantial international funding along with evidence-based clinical practice have resulted in an unparalleled scale-up of access to antiretroviral treatment at a higher CD4 count. The role and timing of highly active antiretroviral therapy (HAART) in mediating cervical disease remains unclear. The aim of this article is to systematically review all evidence pertaining to Africa and identify research gaps regarding the epidemiological association between HAART use and the presence of premalignant/malignant cervical lesions.

METHOD

Five databases were searched until January 2017 to retrieve relevant literature from sub-Saharan Africa. Publications were included if they addressed prevalence, incidence or clearance of human papillomavirus (HPV) infection in women undergoing HAART as well as cytological or histological neoplastic abnormalities.

RESULTS

22 studies were included, of which seven were prospective studies. Women receiving HAART are less likely to develop squamous intraepithelial lesions (SILs). There is evidence that duration of HAART along with the CD4 count may reduce the prevalence of high-risk HPV (HR-HPV), suggesting that without HAART, severe immunosuppression increases the risk of becoming or remaining infected with HR-HPV. Furthermore, according to existent literature, the CD4 count, rather than HAART coverage or its duration, plays a central role in the prevalence of cervical intraepithelial neoplasia (CIN) 2 and CIN 3.

CONCLUSION

Our findings suggest a positive impact of HAART duration, in conjunction and interaction with CD4 count, on reducing the prevalence of HR-HPV. The greatest treatment effect might be seen among women starting at the lowest CD4 count, which may have a more instrumental role in cervical oncogenesis than either HAART use or the treatment duration on the prevalence of CIN 2 and CIN 3. There is still insufficient evidence to show a clear association between HAART coverage and the incidence of invasive cervical cancer. Enhanced surveillance on the impact of HAART treatment is crucial.

Randomized trial evaluating self-sampling for HPV DNA based tests for cervical cancer screening in Nigeria

Background

Cervical cancer incidence and mortality rates in Sub-Saharan Africa (SSA) remain high due to several factors including low levels of uptake of cervical cancer screening. Self-collection of cervicovaginal samples for HPV DNA testing may be an effective modality that can increase uptake of cervical cancer screening in SSA and hard to reach populations in developed countries. We investigated whether self-collection of cervicovaginal samples for HPV DNA tests would be associated with increased uptake of screening compared with clinic based collection of samples. Furthermore, we compared the quality of samples collected by both approaches for use in HPV genotyping.

Methods

We conducted a community based randomized trial in a semi-urban district of Abuja, Nigeria with 400 women, aged 30 to 65 years randomized to either hospital-collection or self-collection of cervicovaginal samples. We compared cervical cancer screening uptake among the 2 groups and evaluated the concentration of human DNA in the samples by measuring RNase P gene levels using qPCR. High-risk HPV DNA detection and typing was done using the GP5+/6+ Luminex system.

Results

Most participants in the self-collection arm (93%, 185/200) submitted their samples while only 56% (113/200) of those invited to the hospital for sample collection attended and were screened during the study period (p value < 0.001). Human genomic DNA was detected in all but five (1.7%) participants, all of whom were in the self-collection arm. The prevalence of high-risk HPV in the study population was 10% with types 35, 52 and 18 being the commonest.

Conclusions

Our study shows that self-sampling significantly increased uptake of HPV DNA based test for cervical cancer screening in this population and the samples collected were adequate for HPV detection and genotyping. Cervical cancer screening programs that incorporate self-sampling and HPV DNA tests are feasible and may significantly improve uptake of cervical cancer screening in SSA.

Precancerous Cervix in Human Immunodeficiency Virus Infected Women Thirty Years Old and above in Northern Uganda

Background. Little is known about precancerous cervical lesion (PCCL), the precursor of cervical cancer among Human Immunodeficiency (HIV) infected women in a postconflict setting of Northern Uganda. Objective. To establish factors associated with PCCL among HIV infected women above thirty years of age in a postconflict setting of Northern Uganda. Method. This retrospective cohort study used electronic data from 995 HIV-positive women that attended cervical cancer screening during June 2014 and December 2015. Data on social, sexual, obstetric, and gynecological factors was analyzed at 95% confidence level. Multivariate analysis determined factors independently associated with positive PCCL. Probability value less than 5% was considered significant. Results. Prevalence of PCCL was 3.0% (95% confidence interval (CI): 2.0–4.3). A positive PCCL was significantly associated with absence of sexually transmitted diseases (STDs) during clinic visits (adjusted odds ratio, aOR = 0.24; 95% confidence interval (CI): 0.09–0.64; P = 0.004) and first pregnancy before the age of 20 years (aOR = 3.09; 95% CI: 1.21–7.89; P = 0.018). Conclusion. The prevalence of PCCL was low in the postconflict setting of Northern Uganda. HIV-positive women presenting with STDs and those with first pregnancy before the age of 20 years were at increased risk of PCCL.

Recurrence of cervical intraepithelial lesions after thermo-coagulation in HIV-positive and HIV-negative Nigerian women

BACKGROUND

The burden of cervical cancer remains huge globally, more so in sub-Saharan Africa. Effectiveness of screening, rates of recurrence following treatment and factors driving these in Africans have not been sufficiently studied. The purpose of this study therefore was to investigate factors associated with recurrence of cervical intraepithelial lesions following thermo-coagulation in HIV-positive and HIV-negative Nigerian women using Visual Inspection with Acetic Acid (VIA) or Lugol's Iodine (VILI) for diagnosis.

METHODS

A retrospective cohort study was conducted, recruiting participants from the cervical cancer "see and treat" program of IHVN. Data from 6 sites collected over a 4-year period was used. Inclusion criteria were: age ≥18 years, baseline HIV status known, VIA or VILI positive and thermo-coagulation done. Logistic regression was performed to examine the proportion of women with recurrence and to examine factors associated with recurrence.

RESULTS

Out of 177 women included in study, 67.8 % (120/177) were HIV-positive and 32.2 % (57/177) were HIV-negative. Recurrence occurred in 16.4 % (29/177) of participants; this was 18.3 % (22/120) in HIV-positive women compared to 12.3 % (7/57) in HIV-negative women but this difference was not statistically significant (p-value 0.31). Women aged ≥30 years were much less likely to develop recurrence, adjusted OR = 0.34 (95 % CI = 0.13, 0.92). Among HIV-positive women, CD4 count <200cells/mm(3) was associated with recurrence, adjusted OR = 5.47 (95 % CI = 1.24, 24.18).

CONCLUSION

Recurrence of VIA or VILI positive lesions after thermo-coagulation occurs in a significant proportion of women. HIV-positive women with low CD4 counts are at increased risk of recurrent lesions and may be related to immunosuppression.

Prevalence and risk factors of cervical squamous intraepithelial lesions among HIV-infected women in Dar es Salaam, Tanzania

To determine the prevalence and predictors of cervical squamous intraepithelial lesions (SIL) among HIV-infected women in Tanzania, a cross-sectional study was conducted among HIV-infected women at HIV care and treatment clinics. A Papanicolaou (Pap) smear was used as a screening tool for detection of cervical SIL. From December 2006 to August 2009, 1365 HIV-infected women received cervical screening. The median age was 35 (interquartile range [IQR]: 30-42) years, and the median CD4 + cell count was 164 (IQR: 80-257) cells/mm(3). The prevalence of cervical SIL was 8.7% (119/1365). In multivariate analysis, older age (≥50 versus 30-<40 years: prevalence ratio [PR], 2.36; 95% confidence interval [CI], 1.45-3.84, p for trend = 0.001), lower CD4 + cell counts (<100 versus ≥200 cells/mm(3): PR, 1.55; 95% CI, 1.01-2.36, p for trend = 0.03) and cervical inflammation (PR, 1.73; 95% CI, 1.16-2.60, p = 0.008) were associated with an increased risk of cervical SIL. Women with advanced WHO HIV disease stage (IV versus I/II: PR, 3.45; 95% CI, 1.35-8.85, p for trend = 0.01) had an increased risk for high-grade SIL. In resource-limited settings where it is not feasible to provide cervical cancer prevention services to all HIV-infected women, greater efforts should focus on scaling-up services among those who are older than 50 years, with lower CD4 cell counts and advanced HIV disease stage.

Implementation and Operational Research: Age Distribution and Determinants of Invasive Cervical Cancer in a "Screen-and-Treat" Program Integrated With HIV/AIDS Care in Zambia

BACKGROUND

Cervical cancer screening efforts linked to HIV/AIDS care programs are being expanded across sub-Saharan Africa. Evidence on the age distribution and determinants of invasive cervical cancer (ICC) cases detected in such programs is limited.

METHODS

We analyzed program operations data from the Cervical Cancer Prevention Program in Zambia, the largest public sector programs of its kind in sub-Saharan Africa. We examined age distribution patterns by HIV serostatus of histologically confirmed ICC cases and used multivariable logistic regression to evaluate independent risk factors for ICC among younger (≤35 years) and older (>35 years) women.

RESULTS

Between January 2006 and April 2010, of 48,626 women undergoing screening, 571 (1.2%) were diagnosed with ICC, including 262 (46%) HIV seropositive (median age: 35 years), 131 (23%) HIV seronegative (median age: 40 years), and 178 (31%) of unknown HIV serostatus (median age: 38 years). Among younger (≤35 years) women, being HIV seropositive was associated with a 4-fold higher risk of ICC [adjusted odds ratio = 4.1 (95% confidence interval: 2.8, 5.9)] than being HIV seronegative. The risk of ICC increased with increasing age among HIV-seronegative women and women with unknown HIV serostatus, but among HIV-seropositive women, the risk peaked around age 35 and nonsignificantly declined with increasing ages. Other factors related to ICC included being married (vs. being unmarried/widowed) in both younger and older women, and with having 2+ (vs. ≤1) lifetime sexual partners among younger women.

CONCLUSIONS

HIV infection seems to have increased the risk of cervical cancer among younger women in Zambia, pointing to the urgent need for expanding targeted screening interventions.

Profile and retrospective analysis of the use of preventive strategies in patients with cervical cancer in South-South Nigeria

Background:

Cervical cancer is the commonest malignancy of the female genital tract in developing countries, with a global burden of 530,000 new cases annually. This study aims to review the current situation of this important malignancy and to assess the previous use of preventive measures in patients with cervical cancer at the Port Harcourt Teaching Hospital (UPTH), Port Harcourt, Nigeria.

Materials and Methods:

This was a retrospective review of all cases of cervical cancer managed at the UPTH, Port Harcourt, Nigeria, between 1 January 2008 and 31 December, 2012.

Results:

The prevalence of cervical cancer was 3.53% of all gynaecological admissions. The peak age of incidence was 50-59 years, accounting for 40% of the study population. Women with high parity contributed to 93.3% of the study population. Early coitarche was observed in 78.7% and a history of multiple sexual partners in 65.3%. Vaginal bleeding was the commonest clinical feature seen in all the women studied, followed by pelvic pain in 84% of cases. Advanced-stage cervical cancer was seen in 93.4%. None of the women studied had been previously vaccinated against human papilloma virus (HPV), and only 1.3% had had any form of screening methods for early detection of cervical cancer.

Conclusion:

Cervical cancer remains an important cancer in our environment, and late presentation with advance disease is still the norm despite advances in screening and preventive modalities. The reason for this is buttressed on the finding that despite the availability of these preventive strategies, women in the South-South of Nigeria did not partake of these measures. There is an urgent need to develop programmes to re-sensitise women on the need for screening and vaccination to reduce cancer-associated morbidity and mortality in Port Harcourt, South-South Nigeria.

Exploring barriers to the delivery of cervical cancer screening and early treatment services in Malawi: some views from service providers

BACKGROUND

Cervical cancer is the most common reproductive health cancer in Malawi. In most cases, women report to health facilities when the disease is in its advanced stage. In this study, we investigate service providers' perceptions about barriers for women to access cervical cancer screening and early treatment services in Malawi.

METHODS

We conducted in-depth interviews with 13 district coordinators and 40 service providers of cervical cancer screening and early treatment services in 13 districts in Malawi. The study was conducted in 2012. The district coordinators helped the research team identify the health facilities which were providing cervical cancer screening and early treatment services.

RESULTS

Almost all informants reported that cervical cancer was a major public health problem in their districts and that prevention efforts for this disease were being implemented. They were aware of the test and treat approach using visual inspection with acetic acid (VIA). They, however, said that the delivery of cervical cancer screening and early treatment services was compromised because of factors such as gross shortage of staff, lack of equipment and supplies, the lack of supportive supervision, and the use of male service providers. Informants added that the lack of awareness about the disease among community members, long distances to health facilities, the lack of involvement of husbands, and prevailing misperceptions about the disease (eg, that it is caused by the exposure to the VIA process) affect the uptake of these services.

CONCLUSION

While progress has been made in the provision of cervical cancer screening and early treatment services in Malawi, a number of factors affect service delivery and uptake. There is a need to continue creating awareness among community members including husbands and also addressing identified barriers such as shortage of staff and supplies in order to improve uptake of services.

Challenges in the detection, prevention, and treatment of HIV-associated malignancies in low- and middle-income countries in Africa

Cancers associated with immunosuppression and infections have long been recognized as a major complication of HIV/AIDS. More recently, persons living with HIV are increasingly diagnosed with a wider spectrum of HIV-associated malignancies (HIVAM) as they live longer on combination antiretroviral therapy. This has spurred research to characterize the epidemiology and determine the optimal management of HIVAM with a focus on low-and middle-income countries (LMICs). Given background coinfections, environmental exposures, host genetic profiles, antiretroviral therapy usage, and varying capacities for early diagnosis and treatment, one can expect the biology of cancers in HIV-infected persons in LMICs to have a significant impact on chronic HIV care, as is now the case in high-income countries. Thus, new strategies must be developed to effectively prevent, diagnose, and treat HIVAM in LMICs; provide physical/clinical infrastructures; train the cancer and HIV workforce; and expand research capacity-particularly given the challenges posed by the limitations on available transportation and financial resources and the population's general rural concentration. Opportunities exist to extend resources supported by the President's Emergency Plan for AIDS Relief and the Global Fund to Fight AIDS, Tuberculosis, and Malaria to improve the health-care infrastructure and train the personnel required to prevent and manage cancers in persons living with HIV. These HIV chronic care infrastructures could also serve cancer patients regardless of their HIV status, facilitating long-term care and treatment for persons who do not live near cancer centers, so that they receive the same degree of care as those receiving chronic HIV care today.

The prevalence of precancerous cervical cancer lesion among HIV-infected women in southern Ethiopia: a cross-sectional study

Introduction

The magnitude of precancerous cervical cancer lesions as well as invasive cervical cancer is higher in HIV-infected women than non HIV-infected women. Thus, screening targeting HIV-infected women is being undertaken in developing countries, including Ethiopia. However, data on the prevalence and determinants of precancerous cervical cancer lesion among HIV-infected women in southern Ethiopia is lacking. Thus, this study aimed to assess the prevalence of and factors associated with precancerous cervical cancer lesion among HIV- infected women in southern Ethiopia.

Methods

A hospital-based cross-sectional study was conducted from October 2012 to February 2013 among HIV-infected women in Southern Ethiopia. Four hundred forty eight HIV-infected women who had been screened and treated for precancerous cervical cancer lesion were included in the study. Data were collected by using structured and pretested questionnaire. Visual inspection with acetic acid was applied for screening and treatment. SPSS version 16.0 was used for data entry and analysis. Logistic regression analysis was fitted and odds ratios with 95% Confidence intervals and p-values were computed to identify factors associated with precancerous cervical cancer lesion.

Results

Out of 448 study participants, 99 (22.1%) were found to be positive for precancerous cervical cancer. Being currently on highly active antiretroviral treatment (AOR=0.52, 95%CI: 0.35, 0.92), history of sexually transmitted disease (AOR=2.30, 95%CI: 1.23, 4.29) and having only one lifetime sexual partner (AOR=0.33, 95%CI: 0.20, 0.56) were factors associated with precancerous cervical cancer lesion.

Conclusions

The prevalence of precancerous cervical cancer lesion among HIV-infected women in southern Ethiopia was found to be high. Intervention to access all HIV-infected women like scaling up the limited services and awareness creation should be undertaken. Measures aimed at preventing the acquisition and transmission of sexually transmitted diseases and reducing the number of sexual partners are required. Besides, early initiation of highly active antiretroviral treatment is important.
