High-risk human papillomavirus distribution according to human immunodeficiency virus status among women with cervical cancer in Abidjan, Côte d'Ivoire, 2018 to 2020. Int J Cancer 2024; 154:962-968. [PMID: 37942579 PMCID: PMC10841473 DOI: 10.1002/ijc.34774] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2023] [Revised: 09/20/2023] [Accepted: 09/21/2023] [Indexed: 11/10/2023]
Abstract
As human papillomavirus (HPV) immunisation and HPV-based cervical cancer (CC) screening programmes expand across sub-Saharan Africa, we investigated the potential impact of human immunodeficiency virus (HIV) status on high-risk (HR)-HPV distribution among women with CC in Côte d'Ivoire. From July 2018 to June 2020, paraffin-embedded CC specimens diagnosed in Abidjan, Côte d'Ivoire were systematically collected and tested for HR-HPV DNA. Type-specific HR-HPV prevalence was compared according to HIV status. Of the 170 CC specimens analysed (median age 52 years, interquartile range: [43.0-60.0]), 43 (25.3%) were from women living with HIV (WLHIV) with a median CD4 count of 526 [373-833] cells/mm3 and 86% were on antiretroviral therapy (ART). The overall HR-HPV prevalence was 89.4% [95% CI: 84.7-94.1]. All were single HR-HPV infections with no differences according to HIV status (P = .8). Among HR-HPV-positive CC specimens, the most prevalent HR-HPV types were HPV16 (57.2%), HPV18 (19.7%), HPV45 (8.6%) and HPV35 (4.6%), with no significant differences according to HIV status. Altogether, infection with HPV16/18 accounted for 71.1% [95% CI: 55.9-86.2] of CC cases in WLHIV vs 78.9% [95% CI: 71.3-86.5] in women without HIV (P = .3). The study confirms the major role of HPV16/18 in CC in Côte d'Ivoire and should support a regional scale-up of HPV16/18 vaccination programmes regardless of HIV status. However, vaccines targeting additional HR-HPV types, including HPV45 and HPV35, could further decrease future CC incidence in Côte d'Ivoire, both for WLHIV and women without HIV.

Circulating natural killer cells and their association with breast cancer and its clinico-pathological characteristics. Ecancermedicalscience 2023; 17:1567. [PMID: 37533944 PMCID: PMC10393315 DOI: 10.3332/ecancer.2023.1567] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/13/2023] [Indexed: 08/04/2023] Open
Abstract
Purpose Natural killer (NK) cells play a critical role in cancer immunosurveillance and hold promise as both therapies and prognostic markers in advanced disease. We explore factors that may influence NK cell concentration in the peripheral blood of women with breast cancer in Côte d'Ivoire compared to healthy controls and implications for future research in our context. Methods In this cross-sectional case-control study, blood samples were taken from 30 women diagnosed with breast cancer within 6 months of diagnosis and fifteen healthy women at University Teaching Hospital [Centre Hospitalier Universitaire (CHU)] Treichville in Abidjan, Côte d'Ivoire, from March to September 2018. The blood draw could take place at any time following diagnosis and through treatment. Demographic and clinical data were collected. NK cells were isolated, stained, analysed and counted using the flow cytometer at the Department of Immunology at CHU of Cocody. All p-values were two-sided. Results Mean age among 30 women with breast cancer was 49 years old compared to 45 years old for 15 controls (p = 0.41). Among 30 women with breast cancer, 4 (13.3%) had Stage 2 disease, 14 (46.7 %) at Stage 3, and 12 (40%) at Stage 4. Fourteen (46.7%) had breast cancer that was hormone receptor-positive (HR+) HER2-negative, 10 (33.3%) had triple-negative cancer, three (10.0%) had HR+HER2+ disease, and three (10.0%) HR-HER2+ cancer. NK cell concentration was not associated with cancer diagnosis, age, cancer stage, subtype, or type of treatment patients received (p > 0.05). Conclusion Although we did not find an association between NK cell concentration, cancer characteristics or treatment, our results be limited by the small sample size and timing of blood draw. Our next steps include a larger study to explore circulating NK cells prior to any treatment and NK cell infiltration within breast cancer tumour and correlating this with response to treatment and prognosis.

Abstract
BACKGROUND/PURPOSE Stage at diagnosis is an important metric in treatment and prognosis of cancer, and also in planning and evaluation of cancer control. For the latter purposes, the data source is the population-based cancer registry (PBCR), but, although stage is usually among the variables collected by cancer registries, it is often missing, especially in low-income settings. Essential TNM has been introduced to facilitate abstraction of stage data by cancer registry personnel, but the accuracy with which they can do so is unknown. METHODS 51 cancer registrars from 20 countries of sub-Saharan Africa (13 anglophone, 7 francophone) were tasked with abstracting stage at diagnosis, using Essential TNM, from scanned extracts of case. The panel comprised 28 records of each of 8 common cancer types, and the participants chose how many to attempt (between 48 and 128). Stage group (I-IV), derived from the eTNM elements that they assigned to each cancer, was compared with a gold standard, as decided by two expert clinicians. RESULTS The registrars assigned the correct stage (I-IV) in between 60 and 80% of cases, with the lowest values for ovary, and the highest for oesophagus. The weighted kappa statistic suggested a moderate level of agreement between participant and expert (0.41-0.60) for 5 cancers, and substantial agreement (0.61-0.80) for three, with the best for cervix, large bowel, oesophagus and ovary, and the worst (weighted kappa 0.46) for non-Hodgkin lymphoma (NHL). For all except NHL, early stage (I/II) and late stage (III/IV) was correctly identified in 80% or more of the cases. CONCLUSIONS A single training in staging using Essential TNM resulted in an accuracy that was not much inferior to what has been observed in clinical situations in high income settings. Nevertheless, some lessons were learned on how to improve both the guidelines for staging, and the training course.

Presentation, patterns of care, and outcomes of patients with prostate cancer in sub-Saharan Africa: A population-based registry study. Cancer 2021; 127:4221-4232. [PMID: 34328216 DOI: 10.1002/cncr.33818] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2020] [Revised: 04/17/2021] [Accepted: 05/18/2021] [Indexed: 12/30/2022]
Abstract
BACKGROUND Although prostate cancer (PCa) is the most commonly diagnosed cancer in men of sub-Saharan Africa (SSA), little is known about its management and survival. The objective of the current study was to describe the presentation, patterns of diagnosis, treatment, and survival of patients with PCa in 10 countries of SSA. METHODS In this observational registry study with data collection from 2010 to 2018, the authors drew a random sample of 738 patients with PCa who were registered in 11 population-based cancer registries. They described proportions of patients receiving recommended care and presented survival estimates. Multivariable Cox regression was used to calculate hazard ratios comparing the survival of patients with and without cancer-directed therapies (CDTs). RESULTS The study included 693 patients, and tumor characteristics and treatment information were available for 365 patients, 37.3% of whom had metastatic disease. Only 11.2% had a complete diagnostic workup for risk stratification. Among the nonmetastatic patients, 17.5% received curative-intent therapy, and 27.5% received no CDT. Among the metastatic patients, 59.6% received androgen deprivation therapy. The 3- and 5-year age-standardized relative survival for 491 patients with survival time information was 58.8% (95% confidence interval [CI], 48.5%-67.7%) and 56.9% (95% CI, 39.8%-70.9%), respectively. In a multivariable analysis, survival was considerably poorer among patients without CDT versus those with therapy. CONCLUSIONS This study shows that a large proportion of patients with PCa in SSA are not staged or are insufficiently staged and undertreated, and this results in unfavorable survival. These findings reemphasize the need for improving diagnostic workup and access to care in SSA in order to mitigate the heavy burden of the disease in the region.

Barriers and facilitators in cervical cancer screening uptake in Abidjan, Côte d'Ivoire in 2018: a cross-sectional study. BMC Cancer 2021; 21:952. [PMID: 34433459 PMCID: PMC8390229 DOI: 10.1186/s12885-021-08650-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2021] [Accepted: 07/29/2021] [Indexed: 12/24/2022] Open
Abstract
Backgrounds Cervical cancer (CC) incidence remains unacceptably high in Côte d’Ivoire. In an effort to prevent this malignant condition, a national CC screening program has been scaled up in the country. This study aimed at assessing CC screening uptake and its associated factors in Abidjan in 2018. Methods A cross-sectional survey was conducted from July to September 2018 in the main healthcare facilities of three randomly selected out of the eight health districts of Abidjan. During the study period, a standardized questionnaire was administrated by research assistants to all women aged 25 to 55 years old, attending the three participating facilities. Demographics, knowledge on CC, personal history of CC screening and reasons for not attending CC screening were collected. A logistic regression model was computed to document factors associated with reported CC screening uptake. Results A total of 1158 women with a median age of 32 years (IQR [27–36]), including 364 (31.4%) with no formal education were included. Of those participants, 786 (67.9%) had ever heard about CC. CC screening uptake at least once was reported by 7.5% [95% CI: 6.0–9.0] participants. In multivariable analysis, being ≥45 years (aOR: 6.2 [2.3–17.2]), having a university level (aOR: 2.8 [1.2–6.6]) (versus non formal education) and access to mass campaign information (aOR: 18.2 [8.5–39.1]) were associated with a reported CC screening uptake. The main reported barriers to CC screening were unawareness towards CC screening (75.5%), negligence (20.5%), fear of CC detection (3.9%) and fear of additional costs (3.3%). Conclusion CC screening uptake remains low despite current initiatives to support awareness and prevention in Abidjan. Awareness campaigns need to be massively increased with the adjunction of tailored messages based on the level of women’s education to enhance the CC screening coverage and reach the WHO goal of CC elimination by 2030.

Changes in HIV-Related Cervical Cancer Over a Decade in Côte d'Ivoire. JCO Glob Oncol 2021; 7:782-789. [PMID: 34043415 PMCID: PMC8457855 DOI: 10.1200/go.21.00006] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2021] [Revised: 02/22/2021] [Accepted: 04/22/2021] [Indexed: 12/24/2022] Open
Abstract
PURPOSE Major improvements have occurred in access to invasive cervical cancer (ICC) screening in HIV-infected women over the past decade in sub-Saharan Africa. However, there is limited information on changes in the burden of HIV-related ICC at a population level. Our objective was to compare HIV-related ICC over a decade and document factors associated with HIV infection in women with ICC in Côte d'Ivoire. METHODS A repeated cross-sectional study was conducted in referral hospitals of Abidjan, Côte d'Ivoire, through the 2009-2011 and 2018-2020 periods. Women diagnosed with ICC were systematically tested for HIV. Demographics, ICC risk factors, cancer stage (International Federation of Gynecology and Obstetrics), and HIV characteristics were collected through questionnaires. Characteristics of HIV-related ICC were compared between the periods, and factors associated with HIV in women diagnosed with ICC in 2018-2020 were documented through a multivariable logistic model. RESULTS During the 2009-2011 and 2018-2020 periods, 147 and 297 women with ICC were diagnosed with estimated HIV prevalence of 24.5% and 21.9% (P = .53), respectively. In HIV-infected women, access to antiretroviral treatment increased from 2.8% to 73.8% (P < 10-4) and median CD4 cell count from 285 (IQR, 250-441) to 492 (IQR, 377-833) cells/mm3 (P = .03). In women diagnosed with ICC during the 2018-2020 period, HIV infection was associated with a less advanced clinical stage (International Federation of Gynecology and Obstetrics I or II stage) (adjusted OR, 2.2 [95% CI, 1.1 to 4.4]) and with ICC diagnosis through a systematic screening (adjusted OR, 10.5 [95% CI, 2.5 to 45.5]). CONCLUSION Despite a persistently high proportion of HIV-related ICC over time in Côte d'Ivoire, HIV was associated with less advanced clinical stage at ICC diagnosis. Recent improvements in ICC screening services across HIV clinics might explain this association and support their implementation across non-HIV health facilities.

Assessment of the scale-up of cervical cancer screening in Abidjan stratified by HIV status. Int J Gynaecol Obstet 2019; 147:246-251. [PMID: 31482577 DOI: 10.1002/ijgo.12959] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2018] [Revised: 05/30/2019] [Accepted: 08/14/2019] [Indexed: 11/08/2022]
Abstract
OBJECTIVE To report the successes and challenges of scaling up a population-based cervical cancer (CC) screening program from HIV clinics to various healthcare facilities in Abidjan, Côte d'Ivoire. METHOD A retrospective analysis of characteristics, outcomes, and follow-up of women attending an initial CC screening visit in Abidjan between January 2010 and December 2014. Data were collected via forms that were systematically completed during CC screening visits. Data from the 2014 population census were used to estimate screening coverage. RESULTS Among 16 169 women attending an initial CC screening, 1616 (10.0%) had a positive VIA test. Among 848 women eligible for immediate cryotherapy, 618 (72.9%) underwent the "see-and-treat" approach. The 1-year follow-up rate after cryotherapy was 23.1% (143/618), and was higher among women with HIV (111/362, 30.7%) than among other women (32/256, 12.5%) (P=0.001). The estimated coverage of CC screening in Abidjan was 1.2% (95% confidence interval, 0.6-3.1). CONCLUSION Despite successful expansion of CC screening from HIV clinics to other facilities, the estimated screening coverage of the targeted population remained low. Follow-up of positively screened and treated women is a major challenge, especially outside HIV clinics, and would benefit from an innovative information system proving unique identification and tracking systems.

Abstract
OBJECTIVES Despite the increasing number of interventions aiming to integrate cervical cancer screening into HIV clinics in sub-Saharan Africa, Women living with HIV (WLHIV) still have a high risk of developing cervical cancer. The aim of this study was to estimate the coverage of cervical cancer screening and associated factors among WLHIV in Abidjan, Côte d'Ivoire. DESIGN Cross-sectional survey conducted from May to August 2017. SETTINGS Outpatient setting in the four highest volume urban HIV clinics of government's or non-governmental organisation's sector in Côte d'Ivoire. PARTICIPANTS All WLHIV, aged 25-55 years, followed since at least 1 year, selected through a systematic sampling procedure. INTERVENTION A standardised questionnaire administered to each participant by trained healthcare workers. OUTCOME Cervical cancer screening uptake. RESULTS A total of 1991 WLHIV were included in the study, aged in median 42 years (IQR 37-47), and a median CD4 count (last known) of 563 (378-773) cells/mm3. Among the participants, 1913 (96.1%) had ever heard about cervical cancer, 1444 (72.5%) had been offered cervical cancer screening, mainly in the HIV clinic for 1284 (88.9%), and 1188 reported a personal history of cervical cancer screening for an overall coverage of 59.7% (95% CI 57.6 to 62.0). In multivariable analysis, university level (adjusted OR (aOR) 2.1; 95% CI 1.4 to 3.1, p<0.001), being informed on cervical cancer at the HIV clinic (aOR 1.5; 95% CI 1.1 to 2.0, p=0.017), receiving information self-perceived as 'clear and understood' on cervical cancer (aOR 1.7; 95% CI 1.4 to 2.2, p<0.001), identifying HIV as a risk factor for cervical cancer (aOR 1.4; 95% CI 1.1 to 1.8, p=0.002) and being proposed cervical cancer screening in the HIV clinic (aOR 10.1; 95% CI 7.6 to 13.5, p<0.001), were associated with cervical cancer screening uptake. CONCLUSION Initiatives to support cervical cancer screening in HIV care programmes resulted in effective access to more than half of the WLHIV in Abidjan. Efforts are still needed to provide universal access to cervical cancer screening, especially among socioeconomically disadvantaged WLHIV.

Abstract
INTRODUCTION Hepatocellular carcinoma is a major concern for Public health in West Africa. In Côte d'Ivoire, the bulk of our knowledge stems from studies conducted decades ago. Our aim was, thus, to assess whether the epidemiological features of this tumor changed recently. METHODS Records from 863 patients diagnosed between 2007 and 2014 were analyzed. RESULTS We observed major drifts concerning hepatocellular carcinoma with regards to the 1970-1980 period. Age at presentation is substantially delayed (49.4±14.1 years) whereas sex ratio decreased substantially (M:F=2.6). Patients seropositive for hepatitis B surface antigen and anti-hepatitis C virus represented 65% and 25% of cases whereas alcohol intake was reported in 36%. AFP level was above 400ng/mL in 36% of cases and tumors were already multinodular and/or metastatic at diagnosis in 77% and 26% of patients. Geographical and anthropological variations were observed with excesses of female cases affecting regions (Lagunes) or linguisitic groups (Kru). North-Mande speakers were more often identified as nonBnonC than others. DISCUSSION Ivorian epidemiology of hepatocellular carcinoma was reshaped during the last decades. These changes, most likely due to the spread of hepatitis C virus, resulted in an older and feminized population of patients. We fear that the current and future prevalence of anti-HCV cases might thwart the expected benefits of anti-hepatitis B immunization. Appropriate measures should be taken to prevent further transmission of hepatitis C in the country.

Abstract
PURPOSE Breast cancer is now the leading female cancer in sub-Saharan Africa, but there is relatively little information on breast cancer characteristics from this region. We studied, on a population basis, the size and stage of female breast cancer at diagnosis in Côte d'Ivoire and Republic of Congo. METHODS Data on tumor size and stage of breast cancer at diagnosis were collected by population-based cancer registries in Abidjan (the capital of Côte d'Ivoire; 141 cases) and Brazzaville (the capital of Republic of Congo; 139 cases) from a random group of female breast cancer cases that were diagnosed in 2008-2009 using the same protocol. RESULTS The majority of breast cancers in both countries were advanced cancers. In Côte d'Ivoire, 68% of tumors were ≥5 cm in diameter and 74% of cancers were stage III or IV at diagnosis; the corresponding proportions in Republic of Congo were 63% and 81%. CONCLUSION These results underscore the importance of increased awareness about early detection of breast cancer, as well as expansion of the capacity to provide appropriate diagnosis, treatment, and palliative care in sub-Saharan Africa.

Abstract
Hepatocellular carcinoma (HCC) is a major public health concern in Sub-Saharan Africa. Early research in Ivory Coast showed that chronic hepatitis B and aflatoxin B1 exposure were the two most important etiological agents of HCC in the country but, surprisingly, no survey analyzing HCC etiologies has been conducted since decades. In a preliminary report, we characterized for hepatitis B and C markers 30 consecutive cases of HCC recruited from Abidjan hospitals between June 2011 and December 2012. Nutritional and lifestyle features of patients were analyzed as well. The mean age of the patients was 53 ± 15 years with a sex ratio (M:F = 2.7). HBsAg was the most frequent viral marker in the series (63 %). All HBV isolates belonged to genotype E. With regards to regional standard, anti-HCV reached a very high level (47 %) in the present series. Hepatitis C was more frequent among patients living outside Abidjan (83 vs 23 %, P = 0.009). Patients living in Abidjan were significantly younger than individual living elsewhere in the country (48 ± 14 vs 60 ± 16 years old, P = 0.038) reflecting a possible role for local environmental pollution in tumor progression. Finally, we observed that patients born in Mandé/Gur-speaking regions (North) were younger (48 ± 14 vs 59 ± 15, P = 0.05) and consumed maize more frequently (80 vs 26 %, P = 0.009) than other patients. Interestingly, maize consumption was associated with a trend for aminotransferases elevation (mean = 1.7-1.8 fold, P = 0.06) suggesting a direct hepatic toxicity of this staple food in Ivory Coast. In conclusion, our work indicates that HCC epidemiology underwent recently major drifts in Ivory Coast.

Cervical cancer prevention in reproductive health services: knowledge, attitudes and practices of midwives in Côte d'Ivoire, West Africa. BMC Health Serv Res 2014; 14:165. [PMID: 24721621 PMCID: PMC4012470 DOI: 10.1186/1472-6963-14-165] [Citation(s) in RCA: 21] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2013] [Accepted: 04/04/2014] [Indexed: 02/07/2023] Open
Abstract
Background Cervical cancer is the most common cancer among women and the leading cause of cancer deaths in women in Côte d’Ivoire. Low resource countries can now prevent this cancer by using HPV vaccine and effective and affordable screening tests. However the implementation of these prevention strategies needs well-trained human resources. Part of the solution could come from midwives by integrating cervical cancer prevention into reproductive health services. The aim of this survey was to assess knowledge, attitudes and practices of midwives towards cervical cancer prevention in Abidjan, Côte d’Ivoire, and to find out factors associated with appropriate knowledge. Methods A cross-sectional survey was conducted among midwives in the urban district of Abidjan, using a self-administered questionnaire. Knowledge was assessed by two scores. Factors associated with appropriate knowledge were determined using a logistic regression analysis. Attitudes and practices were described and compare using the Chi2 test. Results A total of 592 midwives were enrolled, including 24.5% of final-year students. 55.7% of midwives had appropriate knowledge on cervical cancer, and 42.4% of them had appropriate knowledge on cervical cancer prevention strategies. Conferences, courses taken at school of midwifery and special training sessions on cervical cancer (OR = 4.9, 95% CI [1.9 to 12.6], p <0.01) were associated with good knowledge on the management of this disease. Among these midwives, 18.4% had already benefited from a screening test for themselves, 37.7% had already advised screening to patients and 8.4% were able to perform a visual inspection. 50.3% of midwives knew HPV vaccine as a preventive method; among them 70.8% usually recommended it to young girls. Conclusion Despite sufficient knowledge about cervical cancer prevention, attitudes and practices of midwives should be improved by organizing capacity building activities. This would ensure the success of integration of cervical cancer prevention into reproductive health services in countries like Côte d’Ivoire.

Abstract
OBJECTIVE To identify in Ivorian environment, reasons involved in late diagnosis of breast cancer. PATIENTS AND METHODS Retrospective study over 4 years (January 2008 to December 2011) including 350 patients with breast adenocarcinoma. A questionnaire was created and filled according to the medical files of the patients. Linear regression analysis applied to the data showed concordance between the factors and the delay before diagnosis. RESULTS Thus 78.9% of the patients sought for care above 10 months with inflammatory cancers (54%) and necrotic ulcerations (18%). Factors found during interview were the lack of financial means (36%), cultural habits with first intent traditional treatment (41.1%), misdiagnosis (7.1%) and lack of therapeutic care. Yet, when comparing each of these factors to the delay, no significant link was found. Chemotherapy was the first therapeutic method. CONCLUSION In our context, the conjunction of ignorance, poverty and socio-cultural habits were the key factors in late diagnosis of breast cancers in Côte d'Ivoire.

Abstract
Background Cancer is a growing co-morbidity among HIV-infected patients worldwide. With the scale-up of antiretroviral therapy (ART) in developing countries, cancer will contribute more and more to the HIV/AIDS disease burden. Our objective was to estimate the association between HIV infection and selected types of cancers among patients hospitalized for diagnosis or treatment of cancer in West Africa. Methods A case-referent study was conducted in referral hospitals in Côte d’Ivoire and Benin. Each participating clinical ward enrolled all adult patients seeking care for a confirmed diagnosis of cancer and clinicians systematically proposed an HIV test. HIV prevalence was compared between AIDS-defining cancers and a subset of selected non-AIDS defining cancers to a referent group of non-AIDS defining cancers not reported in the literature to be positively or inversely associated with HIV. An unconditional logistic model was used to estimate odds ratios (OR) and their 95% confidence intervals (CI) of the risk of being HIV-infected for selected cancers sites compared to a referent group of other cancers. Results The HIV overall prevalence was 12.3% (CI 10.3–14.4) among the 1,017 cancer cases included. A total of 442 patients constituted the referent group with an HIV prevalence of 4.7% (CI 2.8–6.7). In multivariate analysis, Kaposi sarcoma (OR 62.2 [CI 22.1–175.5]), non-Hodgkin lymphoma (4.0 [CI 2.0–8.0]), cervical cancer (OR 7.9 [CI 3.8–16.7]), anogenital cancer (OR 11.6 [CI 2.9–46.3]) and liver cancer (OR 2.7 [CI 1.1–7.7]) were all associated with HIV infection. Conclusions In a time of expanding access to ART, AIDS-defining cancers remain highly associated with HIV infection. This is to our knowledge, the first study reporting a significant association between HIV infection and liver cancer in sub-Saharan Africa.

Abstract
BACKGROUND/AIM Artenimol-R is cytotoxic in transformed cervical cells and safety in humans is yet to be established. The present study investigates the clinical benefits, safety and the tumor marker effect of orally administered Artenimol-R in patients with advanced cervix carcinoma. PATIENTS AND METHODS Ten patients were treated with Artenimol-R for 28 days. Clinical symptoms, vaginal discharge and pain were followed-up. Adverse events were recorded. Biopsy samples were analyzed by immunohistochemistry for the expression of relevant tumor markers. RESULTS Artenimol-R treatment induced clinical remission with a median time for the disappearance of the symptoms being 7 days. No adverse events of grade 3 or 4 occurred. The expression of p53, Epidermal growth factor receptor (EGFR), and antigen Ki-67 as a cellular marker of proliferation, as well as the number of blood vessels stained by the CD31 antibody decreased, whereas the expression of transferrin receptor protein 1 (CD71) increased. CONCLUSION The current pilot study provides evidence on the improvement of the clinical symptoms and the good tolerability of Artenimol-R in patients with advanced carcinoma of the cervix uteri. A survival trial with Artenimol-R in advanced patients is warranted.

Abstract
AIM OF THE STUDY The aim of this retrospective study was to specify the therapeutic strategy in the management of locally advanced rectal cancers in our practice in front of lack of radiotherapy. PATIENTS AND METHODS This study had concerned 52 patients suffering from locally advanced rectal cancers, with mean age of 44 years old (range: 22-68). Evaluation for down staging was based on clinical, CT scan and intraoperative features. Patients were classified as T4NXM0. Thirty one patients (57,7%) had left iliac colostomy associated with a neoadjuvant chemotherapy, 12 had a left iliac palliative colostomy and 9 had chemotherapy only. RESULTS Thirty two patients (80%) suffered from digestive toxicity due to chemotherapy, 11 patients had hematologic toxicity and 4 other had skin and mucous toxicity. Between the thirty one patients who had colostomy and chemotherapy, 4 (12,9%) responded well and underwent to curative rectal resection, in the remaining patients, the colostomy stayed palliative. The median survey time was 9,5 months. CONCLUSION Our poor results confirmed the need of early detection and radiotherapy in the management of our patients.

Abstract
BACKGROUND There are few data concerning cancer incidence rates in contemporary West Africa. The first data from the cancer registry of Abidjan, the capital of Ivory Coast, for the period 1995-1997 are reported in the current study. METHODS The cancer registry attempts to record data on all new cases of cancer diagnosed in the city of Abidjan, including cases without histologic confirmation of diagnosis. RESULTS Two thousand eight hundred fifteen new cancer cases were registered in 3 years, corresponding to age-standardized (world population) incidence rates of 83.7 per 100,000 in men and 98. 6 per 100,000 in women. As reported elsewhere in West Africa, the principal cancers in men were liver cancer (15%) and prostate cancer (15.8%), with modest rates of non-Hodgkin lymphoma (10.5%) and gastric cancer (4.5%). In women, breast cancer was the most frequent tumor (25.7%), followed by cervical cancer (24.0%) and non-Hodgkin lymphoma (7.3%). In contrast to other registry data from West Africa, Kaposi sarcoma occurs with moderate frequency (7.7% of cases reported in men and 2.1% in women). In the pediatric age group, relatively high incidence rates were found for Burkitt lymphoma. CONCLUSIONS Although there most likely is some underascertainment of cases, so that the actual incidence rates may be underestimated, the cancer profile should be a fair reflection of the true situation. In addition to tumors that are well known to be common in sub-Saharan Africa, such as cancers of the liver and cervix, this urban population shows some features of "Westernization" of cancer patterns, in particular the relatively high rates of breast cancer and prostate cancer. The effects of the acquired immunodeficiency syndrome epidemic are reflected in the moderate rates of Kaposi sarcoma reported.
