PurposeCancer of the prostate (CaP) is the leading cancer among men in sub-Saharan Africa (SSA). A substantial proportion of these men with CaP are diagnosed at late (usually incurable) stages, yet little is known about the etiology of CaP in SSA.MethodsWe established the Men of African Descent and Carcinoma of the Prostate Network, which includes seven SSA centers partnering with five US centers to study the genetics and epidemiology of CaP in SSA. We developed common data elements and instruments, regulatory infrastructure, and biosample collection, processing, and shipping protocols. We tested this infrastructure by collecting epidemiologic, medical record, and genomic data from a total of 311 patients with CaP and 218 matched controls recruited at the seven SSA centers. We extracted genomic DNA from whole blood, buffy coat, or buccal swabs from 265 participants and shipped it to the Center for Inherited Disease Research (Baltimore, MD) and the Centre for Proteomics and Genomics Research (Cape Town, South Africa), where genotypes were generated using the UK Biobank Axiom Array.ResultsWe used common instruments for data collection and entered data into the shared database. Double-entered data from pilot participants showed a 95% to 98% concordance rate, suggesting that data can be collected, entered, and stored with a high degree of accuracy. Genotypes were obtained from 95% of tested DNA samples (100% from blood-derived DNA samples) with high concordance across laboratories.ConclusionWe provide approaches that can produce high-quality epidemiologic and genomic data in multicenter studies of cancer in SSA.
Background. There is a lack of expertise in the procedure of open radical retropubic prostatectomy in West Africa therefore necessitating the training of urologists in the subregion in this procedure. Aim. This report looks at the early outcomes of a single surgeon in this procedure after an SIU fellowship. Methodology. A prospective study of the initial twenty consecutive patients with clinically localized prostate cancer that underwent open radical retropubic prostatectomy at the Korle Bu Teaching hospital, Accra. Results. The mean followup was 19.5 months (range 7 months–36 months). The mean age was 62.7 yrs. For the clinical stage, 60% were T1c and 40% T2a with a mean Gleason score of 6.5. The mean estimated blood loss was 1140.0 mLs with a transfusion rate of 70%. For the pathologic stage, pT2 cancers formed 60%, pT3 25%, and pT4 5% with a mean Gleason score of 6.8. No lymph node involvement was noted. The perioperative complications rate was 15%, a postoperative potency recovery rate of 78.6% with all the patients being continent of urine. The tPSA of 95% of the patients had remained less than 0.4 ng/mL. Conclusion. The SIU scholarship offers an avenue for training in radical prostatectomy for sub-Saharan Africa.
Objective: This study was aimed at identifying Ghanaian traditional medicines used for the management of prostate diseases and their constituents. Reviews of studies conducted on them are also presented. Methodology: This was a prospective study. Traditional Medicine samples from consecutive patients with either lower urinary symptoms (LUTS) presenting at the Urology Unit of the Korle Bu Teaching Hospital (KBTH) in Accra from January 2015 to June 2016 and had a prior treatment with traditional medicines, had the samples retrieved. Additionally, all the 58 licensed pharmaceutical shops in Okaishie, a whole sale and retail depot for medicines in the main business district of Accra, were visited and traditional medicines for the management of prostate diseases acquired. The products constituent as labeled were documented and entered once on a proforma. This study was part of a study on the management of benign prostate hyperplasia at the KBTH approved by the Medical Directorate. The findings were analyzed and presented using descriptive statistics and presented as a table. Results: Eleven products were identified with the main indigenous medicinal plant identified being the root extract of Croton membranaceus. This was the constituent in four products (Uro 500 ® , UR-Quick mixture ® , Prostacure® and prostat®60). Although studies on the basic pharmacology and animal studies have confirmed its effect on the prostate, only one clinical study was identified. Conclusion: Croton membranaceus was the indigenous traditional medicine identified for relieving LUTS due to prostate disease. There is the need for empirical evidence on its efficacy in treating Prostate cancer.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
