BackgroundCancer 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.MethodsA 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.ResultsThe 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.ConclusionsIn 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.

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.

BackgroundCervical 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.MethodsA 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.ResultsA 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.ConclusionDespite 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.
